Simply put, new home construction is the process of building multi- and single family residential homes, large-scale residential developments, or townhouses. This process is often undertaken by developers or investors who build these homes and then will sell them for a profit. When the process starts new home construction starts with designing and planning. Engineers and architects will draw up the building plans for the project based on the specifications of the investor. If an individual has bought a lot in the subdivision then they will draw up a building plan for the homeowners home too. Before they will build one or two houses to be used for open house and to give a prospective home buyer an idea of what the homes will look like, the contractor working on the project will use this time to develop estimates. These estimates will held the investors to finalize the budget of the project. Once the designs are complete the plays will usually be submitted to the local government. This is done to obtain building permits for the project.

Once they have the building permits the contractor can start the earthwork on the site. This will including any grading that needs to be done to create an even level foundation for the new home construction. During this part of the process the earth is removed or added as needed. All underground piping is also installed. If there is going to be a crawl space or basement it will also be added at this time. Once all the earthwork has been done the next step is to start framing the houses using steel or wood studs. The builders will create walls, roof framing, and floors at this stage. They may also install windows and exterior doors. Once the building of the house has been completed it is time to put the roof on to create a structure that is watertight. To give the house a finished look they may install brick or exterior siding.

Once the framing work and exterior work is done it is time to start on the interior work. Electrical and mechanical contractors will run the plumbing pipes and wiring throughout the ceiling and walls. The heating and cooling systems are installed and tested, molding and interior doors are put in place and then the drywall is hung. Next the fixtures and hardware are added and the walls are painted. The new home construction is finished and ready for an inspection by the local authority to make sure that the home meets safety and local building codes. An occupancy permit is issued so the family can move in.

With people’s growing awareness of environmental protection and energy saving, the demand of wood pellet fuel for home heating is also increasing. Because this kind of fuel can not only meet a lot of today’s concerns for renewable energy, but also environmental and energy-saving.

So it is really cool pelletizing by yourself! How to make pellet by yourself?

First of all, you need a machine. Then, with proper materials and right guidance, you will naturally get your own pellets right at home.

The pelletizing procedures involve 5 main processes, they are as follows:

Crushing

First of all, using a wood chipping machine to chip raw wood materials into small pieces, then these small pieces should be crushed into wood powder by hammer mills if necessary.

Drying

It has their own best moisture content when pelletizing, for this reason, drying the raw materials to an ideal moisture content before putting them into machine is a good choice. Generally, 13-15% is the best pelletizing moisture content.

Pelletizing

After drying to ideal moisture content, the materials should be put into the machine for pelletizing. There are several pelletizing machines, such as with ring die, flat die, small scale, diesel motor etc. You can choose any one of them according to your need.

Cooling

After pelletizing, the temperature is about 60-80 degree and pellets’ moisture content is about 15%. In this case, the moisture content needs to be cut down by 3%-4% or 7%-8% by using a cooling machine for storage purpose.

Packing

If the pellet is not for burning purpose directly, bagging or packing procedure is necessary because it can protect wood pellets from affecting damp and make it easy to store.

This article is for the reader who is already familiar with the basics of Xbox overheating. He has already tried using his machine in cool, well ventilated locations, away from other sources of heat, limits the hours of usage, keeps the vents clear of dust and obstructions, and keeps the power brick clear of carpeting. I will discuss how a bad connection between the CPU and it’s heat sink or the GPU and it’s heat sink can cause drastic overheating problems.

In the best of circumstances, the Xbox has a cooling system that barely keeps pace with normal heat buildup. Because it has little cooling capacity to spare, it doesn’t tolerate abuse well. Most people would reasonably expect that an Xbox, however badly abused, should take at least a few minutes to overheat.

So if your Xbox gets the 2 red light error (indicating overheating) within seconds of turning it on after a cold start, you may be wondering how this could even be possible.

One reason for such rapid overheating is that either the CPU or the GPU have become detached from their heat sinks. A heat sink is a device that draws off excess heat. In order to do its job properly, the heat sink must be in good thermal contact with the CPU (or GPU as the case may be).

A CPU or GPU can heat up extremely rapidly if it gets no cooling at all. Both of these units consume a lot of power for their size. Only a few seconds would be required for this electrical power to overheat an un-cooled GPU or CPU. This overheating is so rapid that the rest of the console would not even have time to warm up when the overheated CPU or GPU causes the Xbox to shut down. So you end up with a console that still feels cool but is flashing the two red light error.

There are a number of ways that the heat sink can lose thermal contact. Either the thermal paste is extremely old, or too much thermal paste was initially applied, or there’s no paste at all. Perhaps the wrong washers (too thick) were used during the assembly process or the heat sinks were not bolted down properly or perhaps Microsoft left some foil on the heat sink.

When replacing the thermal paste, remember to clean off the old paste first. An alcohol wipe should work for this. Avoid placing too much thermal paste as only a thin film is needed to ensure that there’s no air pockets between the heat sink and the CPU (or the GPU). A good paste to use is Arctic Silver. Keep track of the spacer washers that you remove because they must be placed back during reassembly.

If you’ve never attempted this before but are determined to do this yourself, it is strongly recommended that you get a guide for this kind of repair. Also note that your warranty is voided once you open the console. Good luck.

The Problem

When a water cooled power cable is used in severe environments such as powering an EAF (Electric Arc Furnace) in a steel mill there is an enormous potential for heat, flames, ash or molten splash to severely damage the electrical cables (or series of cables) thus crippling the melting operation. This translates into unscheduled maintenance and lost production time. In some instances these costs have been estimated as high as $100,000 / hr depending on the size of the operation and production schedules.

The water-cooled furnace power cables provide a flexible source of power to permit movement of the electrode arms up and down and to allow swinging the electrode arms and roof back and forth when charging the furnace. The power cables consist of copper wire strands forming a round spiral construction which are attached to copper terminals at either end of the cable. A low temperature rubber jacket around the outside of the cable allows cooling water to flow through the cable assembly. The rubber hose is attached at either end of the cable using stainless steel clamps, vulcanized bumpers or an anti-chaffing type hose.

The danger is that molten metal splash caused by “wet charges”, or flame impingement, extreme heat, etc. will damage an unprotected power cable. This can cause a chain reaction of catastrophic events including loss in water cooling resulting in overheating or shorting of the electrical power cables and halting the melting process.

Given the large diameter of the rubber hoses surrounding the power cables and proximity to the EAF, there is a significant landing area for sparks, molten metal splash, etc. In many applications the cables are left completely unprotected and exposed to severe high temperature environments. In some cases the rubber cooling water hose is wrapped with inexpensive fiberglass tape or sleeve that offer minimal protection against possible hazards.

The Solution

With a minimal capital investment, Worbo Inc.’s severe duty protective molten splash away sleeve may be installed to wrap around new or existing water cooled power cables to resist heat, flame, ash and large intermittent exposure to molten metal splash. Worbo Inc’s development of a highly flexible, molten splash resistant, easily installed and completely non-conductive sleeving solution is a perfect fit for this application.

The Technology

Manufactured and designed with 100% Non-Conductive materials specifically for safe non-arcing use in close proximity to AC or DC EAF’s.

The hydrophobic, low surface energy, non-stick “Splash Away” properties of the thick silicone coating sheds large random but potentially hazardous amounts of 3000˚F molten metal splash to help maintain the integrity of the water cooled power cable until the next scheduled maintenance period.

Equipped with a hook and loop self gripping closure, EAF Cable Molten Splash away sleeve is easily field installed (or removed for maintenance) without cable disconnection.

High Shear and Peel Hook and loop self gripping closure is designed specifically for this application to ensure closure doesn’t separate during severe “jumping”, “bouncing” and “bumping” of cables during furnace arc and “cold starts”.

Combination of Heavy duty “Splash Away” silicone shield coating on thick high temperature fiberglass substrate helps insulate and defend against intermittent bouts of molten metal splash, flame impingement, burning airborne particles and high temperatures.

The Economic Benefits

Depending on the application the cost to procure and install a high temperature jacketing system could be as low as $30/ft. Relative to the enormous costs associated with unscheduled maintenance and lost production time this represent an insignificant capital investment that could pay for itself several times over through the prevention of a single unscheduled maintenance event.

The Conclusion

Protecting electric arc furnace power cables exposed to sever high temperature environments with a high temperature jacketing system will significantly reduce unscheduled maintenance and lost production time.

Digital advertising has many assorted uses on the shop floors of industrial plants and other places of work. Its key use is to give data to workers, like manufacturing quotas, new working practices, health and safety problems, touring dignitaries and critical reminders associated with the day-to-day organization of the company. Any number of LCD advertising boards can be situated on the factory floor, based on the size of area and number of workers.

The media is quick to refresh and update as it can be also remotely accessed via the world-wide-web or in-house intranet, or by uploading the statistics onto a memory device and inserting it into the screen access point. This can be prepared in advance and set to run at explicit times, appropriate to the shift workers on the shop floor.

Much study has shown it can have a positive effect on production as little time is lost through workers’ group meetings and is visually aesthetically pleasing. It can be run with or without sound, where suitable and much more notice is taken of the moving campaigns than that of a none moving poster, or hastily written notice. Another benefit is more than one piece of information can be displayed uninterruptedly therefore several can run concurrently.

This has shown to have a constructive stimulus on workers, as information is displayed instantaneously and is rerun for reminders. It can also be utilized for social events, the refectory menu for the week, fund-raising and moral boosting. Data can of course be streamed to the office workers, were applicable.

As Digital Signage is a fitting marketing medium for both outside and inside use, extremes of weather need to be catered for.

Putting a LCD advertising screen in a ski resort is an exceptional thought, as it can offer so much data and promotion for local organizations, however with the harsh winter temperatures of -30 degrees Fahrenheit, the equipment within the poster frame demand protection. The damp from the snow, turns to ice and can destroy a hard drive therefore a thermostatically controlled temperature device needs to be deployed.

Similarly, in the scorched desserts of Arizona, electronic signage and interactive menu boards have their place too, in outlets like dining places and even a cattle diary, where milk quotas and production is monitored. This without doubt needs a thermostatically controlled cooling unit to control the soaring temperatures, without damaging the delicate systems.

Once connected to the power supply, these cooling or heating systems can be left to run, with minimal monitoring, as the thermostat will trip on or off as required, so does not have to be controlled manually. As the temperatures change in the night, as the instance of the dessert, where it can be particularly hot during the day, falling to sub-zero temperatures at night, this would need a dual controlled thermostat. The power supply is available in each countries own unique wattage, for instance, America is 120 Volts, most of Europe runs on 230 Volts (formerly 220 V) and United Kingdom used 230 Volts (formerly 240 V). The provider of the digital posters will be responsive of this and will give an opinion prior to buying.

PEX, otherwise refereed to as Cross-linked polyethylene, is a form of tubing formed from a high density polyethylene substance to make tubes or pipes commonly used in a wide range of domestic as well as commercial applications. The technology used to create PEX tubing makes the appliances to be resilient against very high as well extremely low temperatures, making them ideal for plumbing and radiant heating.

Some of the common areas where you would need to use PEX include hydronic radiant heating and cooling systems in homes and industries, electrical cables with high voltage, in refrigeration systems and also in water piping. Due to their ability to resist chemical wear-down, PEX pipes are also idea for transporting chemicals, offshore oil, natural gas as well as slurries and sewage.

Classification of PEX Pipes

Basically, there are 3 types of PEX pipes; PEX-a, PEX-b and PEX-c. Although the types are not based on the rating of their application, having some basic knowledge about each can help you choose the best type of PEX pipe to suite your specific needs.

PEX-a

PEX-a is manufactured through a peroxide (or Engel) process by cross-linking the polyethylene molecules. The process is done on a high temperature, normally above the melting point of the peroxide crystals. The result is a material which is very strong and resilient to any sort of mechanical tear. PEX-a pipes are very strong yet flexible. They have fewer joints and require little fittings, making them most suitable for plumbing and radiant heating.

PEX-b

PEX-b is processed through a method called moisture cure, which uses Silane. Cross-linking of the substance elements is facilitated by a chemical agent under optimal temperature and moisture. The resultant PEX is a strong material, but which is a bit more stiff than PEX-a.

PEX-c

PEX-c is made through an electronic beam or radiation. The process involves passing the polyethylene through an electronic beam several times so as to achieve the needed degree of cross-linking. PEX-c is made through a much energy-conscious process, and so, the resultant material is not as resilient as PEX-a and PEX-b; it is a bit fragile. Consequently, PEX-c materials are less expensive than the other PEX tubing. These pipes are more suitable in environments where there are no extreme temperatures or high probability of mechanical hostility.

As we know, the rhythm of modern life is so intense. People are busy with their work, activities and entertainment during the day. Therefore they like washing hair in the evening when they are free.

Of course, it is OK if you have enough time for the hair drying out when you wash hair in the evening. But sometimes you are too busy to wash hair before 10 pm, and you feel so tired after washing that you always go straight to bed and sleep before the hair is totally dry. To do so, the elders will say that will cause headache later. In fact, their words are somewhat reasonable through modern scientific research.

We must know that the human body always produce heat continuously in the metabolism process to maintain the body temperature. And the heat would be transferred to surface layer of organism through blood circulation and emanated to the outside with ways of radiation, conduction, convection as well as evaporation.

For those with strong body resistance and normal regulating function, the two processes of heating and cooling are in balance, that is to say heat will increase when the body temperature declines, which make the body temperature remain at around 37 C. But for people who have weak body resistance and poor regulating function of body temperature, they are easy to get cold by whole or local exposure to cold.

After we wash hair with warm water, the capillaries of the scalp will dilate due to warm effect and the heat of the body radiating around will increase. Meanwhile, the wet hair will cause a lot of water to evaporate, which take away much heat. Generally speaking, 500 calories will be taken away when one gram of water evaporates.

As the heat loss increases and the body gets cold, the capillaries of the upper respiratory tract shrink reflectively, partial blood flow volume reduces and the resistance of the upper respiratory tract decreases, which lead to that existed virus or bacteria get a chance to step in, grow and reproduce. It will result in the respiratory tract infections, which make people have flu symptoms such as runny nose, stuffy nose, headache or fever.

So generally speaking, you should avoid washing hair before going to bed. Even if you had to do that, you should towel your hair dry. In this way you will not catch cold.

There are measures to take before performing jelqing exercises that we have already discussed. This includes ingesting foods that will increase circulation to the pelvis and penis; as well as applying a moist-hot towel to the penis. What measures should we take, if any, during the post-exercise “cooling off” phase?

First of all, let’s give a basic outline of what jelqing is, also known as “milking.” This is a natural form of penis enlargement that utilizes methods of squeezing and milking the penis to encourage more blood into the blood-filled chambers of the penis that create an erection. By forcing more blood into these chambers, we can increase the size of these chambers, and thus encourage the penis to grow larger in size.

Because the penis uses a hydraulic mechanism of blood to create and maintain an erection, we are very interested in increasing the amount of blood flow into the pelvis to feed the penis. This increased capacity of blood flows occurs by something called “vasodilation.” Vasodilation is the ability for the arteries to increase in size so that they can handle more blood volume and more blood flow. So it is important to encourage this blood flow during the jelqing process, as the entire process relies on increasing the amount of blood flow to the penis through exercising measures.

Many men think that after they have finished their jelqing exercises that they are finished. No. This is not correct. Once exercising has been completed now comes one of the most critical stages of jelqing. For, after the jelqing process, the tissues have been accentuated in size because of the extra blood flow forced into them. They are at their ripest for enlargement and need one very important thing to heal the tissues and keep the increased capacity in these cavities. And that is blood. Not any type of blood, but fresh blood. Fresh blood contains nutrients and oxygen that used blood (that is sent off in the veins) does not have. In order to properly heal up you need a constant supply of fresh blood. You also want to help increase the blood flow to the area to help keep the penile cavities enlarged as much as possible (obviously, they won’t be at the size during the jelqing process, but you still want to encourage as much blood volume as possible).

One way to accentuate the jelqing process during the “cool off” phase is by applying a hot and moist towel to the penis. Wet heat is much more penetrating than dry heat, so it important that the towel is moist. You can soak it in water and put it in the microwave (it’s best if the fibers are natural – like cotton – if you utilize this procedure), or moisten and heat up the small towel with running hot water. Make sure the towel does not become too hot, as the skin and tissues of the penis are especially fragile after jelqing and you don’t want to injure them. Apply for at least five minutes after jelqing.

You can also enter a steam room, sauna, hot shower (projected at the genital region), or hot tub after the process. These are the most efficient methods. They will help increase circulation of fresh blood to the pelvic and penile regions, which is what one needs to create an environment for proper healing and increased blood flow.

Before you start to jelq, it is advised that you visit a urologist to rule out any pre-existing conditions you might have that may be deleterious to jelqing.

Background on Plastic Injection Molding

It is the technique of producing parts of thermoplastic and thermosetting plastic by blending and binding into molds and cooling them to mold into an intended object. This injection process that we are going to talk about in this article is not a fresh concept its existence can be witnessed since 1872. Only after the discovery of the molding, the plastics industry experienced huge earnings in billions and hence this is now considered to be one of the best molding methods available.

Benefits of Plastic Injection Molding

As said above it is the most adopted technique for manufacturing a large volume of parts. To give a precise shape and size to the desired object this process focuses on using a heated barrel and a special molding cavity. A bulk of the products available in the market has proven to be the beneficiary from plastic injection molding. The different industries listed below are the ones that have been benefited the most:

1) Electronic Industries: Electronics are being manufactured through the process of plastic injection molding reason being that plastic does not ingest humidity and does not enlarge when exposed through heat.

2) Toys: All kinds of toys available in the market, whether they are feature action figures or detailed collector’s toys are produced through plastic injection molding.

3) Medical: Some of the equipment and tools that surgeons use such as cups, vials and, jars required for sample collection and throw away forceps are made of plastic injection molding.

4) Shoes: Plastic injection molding helps in developing the desired shaped soles that in turn provides support and comfort to the shoes.

5) Food and Beverages: Millions of restaurant and food outlets spread across the world are using plastic spoons, plates and, forks which are the ultimate products of plastic injection molding.

Requirements and Skills for Injection Molding Operators

Before the production of a molded product, the first sample needs to be submitted to an inspector for inspection. After the inspector notifies it as qualified, it is then processed further for mass production. After getting the product as notified and producing in bulk, each carton must have the details on the production card.

When it comes to giving a precise shape and size there is a need for using proper tools such as blades and diagonal pliers. The right use of clamp and fixture and need to operate strictly as per the clear instructions of each fixture is important. All the process is dependent on how the machine works and which machine to use that promise to provide safety. Any abnormal production or abnormal product quality needs a technician on an immediate basis to deal with it.

JasonMould founded in 2010 is a prominent plastic injection molding manufacturer in China. JasonMould specializes in mold production for electronic equipment, household appliances, medical equipment, surgical equipment as well as monitoring systems. This company that possesses different machinery and expertise offer tools from small and precise mobile phone parts to the big automotive parts. The diversion strategies adopted by JasonMould have been winning compliments from customers all over the world.
