UHMWPE features: excellent wear resistance, good low temperature impact resistance, self-lubricating, non-toxic, water and chemical resistance, heat resistance is better than general PE, the disadvantage is heat resistance (heat distortion temperature) Low, poor formability, outer surface hardness, rigidity, creep resistance is not as good as general engineering plastics, and the expansion coefficient is too large.
UHMWPE has poor activity and high viscosity in molten state. It is a rubber-like high-viscosity elastomer. It can only be formed by pressing and sintering at an early stage. It can also be processed by extrusion, injection molding and blow molding.
UHMWPE can replace carbon steel, stainless steel, bronze and other materials for textile, paper, food machinery, transportation, medical, coal, chemical and other parts. Such as the textile industry, such as shuttles, shuttle sticks, gears, couplings, sweeping bars, buffer blocks, eccentric blocks, rod bushings, swinging consequences and other impact-resistant wear parts. In the paper industry, the cover plate, the wiper plate, the compacting parts, the joints, the sealing shaft of the transmission machinery, the deflecting guide wheel, the scraper, the filter, etc.; the hopper, silo and chute of the powder industry in the transportation industry Lining. UHMWPE can be used for a variety of mechanical components, including food machinery gears, worm gears, worms, bearings. Pumps, valves, baffles, filter plates in the chemical industry. Medically, it can also be used for heart valves, short surgical parts, artificial joints and birth control implants. Sports skating floors, rolling earth roads, snowboards, and motorized sled parts. UHMWPE can be used as a high modulus fiber to make body armor, aircraft seats, shipping, fishing ropes, etc.
Compact Solar Water Heater is a cost-effective system for residential hot water application. This system is designed according to thermosiphon principle and operating with proportion difference between cold and hot water. The water heated by Vacuum Tubes is held in the stainless steel storage tank where the insulation preserves the heat.
The compact Solar Water Heater uses the sun to heat the working fluid (mostly water) in the vacuum tubes. The Solar Collector absorbs solar radiation, and converts the sunlight to heat and transfer it to the water. The heated water naturally rises through the solar collector into the water tank where the cooler water at the bottom of the tank is forced out and descends to the bottom of the collector (thermosiphon circulation). The circulation will be interrupted when there is no solar radiation.
