Russia'S UHMWPE Fiber Comes Out
Ultra high molecular weight
polyethylene
Fiber, is located in carbon fiber, boron fiber, aramid fiber after the fourth kinds of high-strength fiber.
It has high strength, high modulus, chemical resistance, light fastness, and humidity resistance, impact resistance and resistance to cutting. It has good biocompatibility and is the least dense among all high strength and high modulus fibers.
Light and tough
。
Russia's "synthetic fiber research institute and Experimental Factory", that is, the former all Su synthetic fiber Science Research Institute, was built in 1956, and has worked with other Russian enterprises for the first time to complete the entire production process of UHMWPE fiber produced in Russia, from fiber synthesis,
Catalyzer
To produce high strength and high modulus yarn and its composite materials, Russia is the first super high molecular polyethylene research project, using gel spinning ultra stretching method, with an annual output of 25 tons.
Russia produces ultra-high molecular weight polyethylene fiber, there are a number of models, their technical indicators: - 1 - type wire tensile strength 270-280cN/tex, elastic modulus of 9000-9500 cN/tex.
The tensile strength is 2 cN/tex, and the elastic modulus is 13000-13500 cN/tex. The tensile strength is 350-370.
It is mainly used for bulletproof bulletproof armor, bulletproof helmets, bulletproof armor, aerospace parachute rope, and composite reinforcement.
1 - type silk fabric is used for reinforcement.
Compound material
Its main performance index is higher than that of Russian aramid PycaP fabric reinforced composites. The bending stress increases by 35% when bending, and the type 2 is expected to increase more.
The production of ultra high molecular weight polyethylene (UHMWPE) fiber in Russia has begun to take shape in 2011. It plans to complete commercial operation in 2015 and form an annual production scale of 120 tons.
The price of two kinds of silk is lower than that of Russian aramid PycaP, which is 1/3 to 1/4 lower than that of Russian polyacrylonitrile based carbon fiber.
