Glass fiber tensile strength is high, elongation is small (3%), the test method standards are: GB / T14338-1993 synthetic short fiber crimp test method, GB / T 15232-1994 textile glass fiber felt tensile strength determination GB / 7689.5 Determination of tensile strength and breaking elongation of

There are two kinds of glass fiber production process: two molding - crucible drawing method, a molding - pool rolling method.Crucible drawing process a wide range of glass raw materials at high temperature into a glass ball, and then the second glass ball melting, high-speed drawing made of glass f

The simple method of testing is to put the fiber in boiling water and cook for 6-7h. If it is high alkali glassy nitrocellulose, after boiling water, the warp and weftThe whole part becomes loose.According to different standards, glass fiber classification methods are many, generally from the length

D glass Also known as low dielectric glass, for the production of dielectric strength of low dielectric glass fiber.In addition to these days to share the article in the glass fiber composition classification, there is also a new E-glass fiber, it is completely free of boron, thereby reducing enviro

E-CR glassIs an improved boron-free alkali-free glass for the production of good acid and water resistance of glass fiber, the water resistance than alkali-free glass fiber to improve 7 to 8 times, acid resistance than the alkali glass fiber is also a lot of For the underground pipes, tanks and othe

Glass fiber (English name: glass fiber or fiberglass) is an excellent performance of inorganic non-metallic materials, a wide range of advantages is good insulation, heat resistance, good corrosion resistance, high mechanical strength, but the disadvantage is the Crisp, poor wear resistance. It is m
