UHMWPE Rod

UHMWPE rod is an amazing engineering plastic which can solve many problems that other engineering plastics cannot. UHMWPE Rod is not as well-known as other plastics but is still highly important and has clear advantages over other more common engineering plastics.

Because UHMWPE rod has excellent abrasion resistance it is often used for sand, gravel or aggregate process applications. These environments are incredibly harsh on any bearing material but UHMWPE is one of the few engineering plastics capable of withstanding such punishing abuse.

 

UHMWPE Rod can also be used for low friction pulleys because of its very low co-efficient provides a bearing medium that is very free running and exceptionally long lasting. It is often found in food production environments where high volumes of containers need to be guided along conveyors or production lines. Because it has very low moisture absorption, it is also found in some high demand areas of marine applications. It’s sometimes used in some cryogenic components due to its low operating temperature abilities.

 

Because of its resistance to wear and impact, UHMWPE continues to find increasing industrial applications, including the automotive and bottling sectors. Since the 1960s, it has also been the most commonly used material for total joint arthroplasty in orthopaedic and spine implants.

 

Application for UHMWPE Rod:

 

• UHMWPE rod is usually chosen for it's low co-efficient of friction and so means it will produce bearings, bushes or pulleys that are highly free running, low friction and durable
• UHMWPE rod is also remarkably abrasive resistant. Therefore the UHMWPE rod can be used in high demand environments such as grit or gravel and have a longer life span when compared to other materials
• UHMWPE rod can often be used in high demand components in the food industry because it has a very low moisture absorption. UHMWPE rod has FDA approval and means that bearings etc. will not expand due to any moisture absorption
• UHMWPE rod is used in the marine industry for pulleys because of its low friction and minimal moisture absorption

 

 

Advantages of UHMWPE Rod:

 

•     UHMWPE is odourless, tasteless, and nontoxic,
•      Has extremely low moisture absorption
•     Very low coefficient of friction
•     Self-lubricating and is highly resistant to abrasion.
•     Very resistant to water, moisture, most chemicals
•     Resistant to UV radiation, and micro-organisms.
•     UHMWPE only becomes brittle at temperatures below −150 °C.

Fish Feed Extrusion Process with Extruder Machine

The early-stage extrusion processing was mainly used in food processing industry. Since the nineteen fifties, America had started to use this technology for feed processing field, especially for processing pet food and pretreatment of feed ingredients. 

Till the nineteen eighties, it has become the fastest developing technique of feed processing industry in the world, and has started to be applied in each sphere of feeding stuff industry, widely used for dry pet foods, some applications for livestock feed and fish feed. With the unceasing development of technology and the continuous rising of people living standard, the growth of aquaculture must follow the principle of producing green food without pollution, bringing significant attention and lots of intensive study on aqua feed production technology. And there is a consensus that adopting extrusion process to make fish feed is the major means to ensure producing high quality and safe aquatic products for human health, which is also a trend for feed industry progress in the future.

Commercial fish feed extrusion process refers to cook the mixture of feed ingredients under high temperature, moisture and high pressure by means of fish feed extruder within short time, whereby the high temperature is a direct result of friction(dry extrusion) or preconditioning and steam injection (wet extrusion). As a technological treatment, extrusion can make it possible to process a variety of fish feed ingredients, such as soybean, corn, rice, peas and raw materials with high water content. According to the moisture content of raw materials treatment, fish feed extrusion process can be divided into two types — dry type extrusion and wet type extrusion.

Currently, the main extrusion equipment applied in aquatic feed production is single screw fish feed extruder which is also divided into dry type fish feed extruder and wet type fish feed extruder machine. With different parameters and feed formulation, fish farmers and feed plants can make floating, sinking and slow-sinking feed with high quality and nutrition so as to adapt for diverse ingestion requirements of various aquatic animals. Adopting alloy steel as material, FANWAY dry type fish feed extruder has been widely used in small-scale and medium-scale fish farm or feed plants to produce aqua feed and also dog/cat pet feed in virtue of its simple structure and low noise. Other than dry type, the wet type fish feed extruder machine is equipped with a boiler that can add vapor constantly into chamber when extruding feed ingredients, which makes it widely applied to produce floating fish feed pellets for fish farm, aquaculture and even poultry farms.

Polycarbonate Sheets Vs. Plastic

Polycarbonate sheets have been proven to be superior to other plastic materials used in similar applications in almost every area of comparison. Furthermore, with various categories in polycarbonate available, it is polycarbonate multiwall sheets that are the finest ones as they perform the most effectively for long years with low maintenance and provide excellent value for money. Made from extruded sheets, there are no thickness variations seen in these sheets, unlike other plastics. Let us compare polycarbonate and plastics in a few areas of functionality to see which one proves better.

Polycarbonate provides up to 89% light transmission while plastic provides 80%.
Polycarbonate provides excellent impact and weather resistance, compared to the average resistance in case of plastics.
Temperature resistance in case of polycarbonates ranges up to 120 degree Celsius, while in case of plastics is only below 100 degree Celsius.
Polycarbonate is self-extinguishing and plastic is flammable.

With all these properties, you can get a clear understanding of why polycarbonate is far better than plastic. Last but not the least, polycarbonate is far more easier to maintain than plastic.

Types of polycarbonate sheets

Solid and textured polycarbonate sheets
Solid and textured sheets can withstand weather extremities, may it be heavy rains, scorching winters or zero degree winters. They have high impact strength, durability, flexibility, and are transparent and light weight. They also possess thermal and chemical resistance. They are also easy to cut and drill. Moreover, they are very easy to store, handle and install. Besides, they are also available in embossed texture that gives the appearance of frosted glass, thus enhancing the look for indoor and outdoor applications.

Multiwall polycarbonate sheets
Multiwall sheets are those versatile sheets that provide outstanding flexibility, heat reflection and light transmission. They are manufactured from high quality polycarbonate resin that provides high impact strength, transparency and light-weightiness to the sheets.

The Brief Description of Pipes and Its Various Applications

Plastic pipes are found under the wider category of industrial pipes. These include systems that help to preserve the requirements of the environment. Usually, they are favored because of their assurance on energy ability while thousands of products are going through manufacturing procedures. The Storm Water Pipe & Fittings are lightweight considering that they are long lasting. Since they are flexible, they do not use as much energy during fabrication, shipping and fitting methods when compared to concrete or metal choices for piping systems. The plastic pipes are reliable even when corrosion and abrasion resistance are being talked about. They also provide leak safety, which makes them highly supportive in several applications that are further explained below.

 

Water System Application:

This kind of industrial pipe has been extensively accepted in municipal as well as industrial water systems. Using high density polyethylene, the water systems are assured to be free from leakages and can be moved from one place to another without much difficulty.

 

Drainage System Application:

The crumpled polyethylene pipe is considered as one of the durable, reliable and cost effective solutions for drainage systems. Even in severe hard weather conditions such as storm, this piping system is mostly preferred from the best Pipe Distributors Adelaide.

 

Fuel Gas Applications:

Fuel gas delivery was listed as one of the first utilization for plastic piping systems. This type of pipe is admirable in the industry because of its lightweight and flexibility that are available in long coils.

Heating & Plumbing Applications:

As for heating and plumbing applications, the pipes are selected not only because it has the capacity to resist corrosion but also because it prevents alkaline solutions, salts, fat and oil.

Extruder clogged at mid-print?

The first tip is, and believe, it is a must-have! its a filament dust filter. its pretty simple and you will only need a bit of filament to print, a small sponge and a bit of oil (optional but recommended)

After you print this filter, cut a small block of sponge (a new kitchen sponge is great for it), and put it inside the filter. you can also use the filter to help the filament trough the pfte tube (used on Bowden setups), a few drops of oil will help a lot with the friction for months.

The second tip is even easier, do not keep the plastic away from its bag! but why? three main reasons!

Dust will accumulate on it

Humidity and air pollution will decrease the filament quality over time, it will break easier and this is a huge problem if you use bowden setup with corners

Three: Sun light is known to crack plastic over time, thus decreasing its quality

Third tip: Research the manufacturer on the internet before buying, there are both good and terrible options, price doesn’t means anything! trust me!, once i’ve bought a 60$ filament, and guess what? it was terrible! a 10$ one from china was incredibly best.

Fourth tip: Not always clogging means bad filament, sometimes there is something wrong with the nozzle and the stepper, follow this checklist:

1 > Thermistor!

Check the nozzle temperature!, the thermistor might break or get loose over time, maybe it showing 200C but actually its 160C. check if it is okay. a laser thermometer is great for it. Warning! Loose thermistor are known to cause the printer to get on fire! This is extremely dangerous!

2 > Nozzle Cleaning

2.0 > Heat the extruder to 160C and remove the filament inside,

2.1 > Heat up the extruder up to 300C (don’t worry), and wait for 30 seconds after the temperature gets to 300.

2.2 > load filament in the extruder and try to extrude about 1 meter! (it will take some time), if there are failures you should remove the filament and try again from step 1. until it comes out linearly. Be sure that the extrusion speed is not too fast,

2.3 > If the filament is going out ok, try printing again, it should have worked. if not, you might need to open it and do a harder cleaning, with drill and some needles. try this tip a few times, remove and insert the filament and try to insert again.

3 > All-Metal extruder refrigeration

This is a common issue, the all-metal extruder is composed of three parts, Heat dissipator; Heat-break and the Heated block

The heat dissipator and the heat-break work together to keep the heat only at the block. a bad quality heat-break will let too much heat go up to the dissipator, which will get too hot and melt the filament where it was not supposed to and will make it jam. Make sure you use one with a PFTE core.

There is also the cooler! you need a good quality cooler to help the dissipator, if you don’t use one, this might be the problem.
