Twist roving fabricSquare cloth is a roving plain weave fabric, is an important substrate for the paste glass fiber reinforced plastic. The strength of the grid is mainly in the weft direction of the fabric, for the requirements of the warp or weft strength of the occasion, can also be woven into a

non-twist rovingThe roving is made of parallel raw wire or parallel monofilament. Twistless roving according to the glass composition can be divided into: alkali-free glass roving and alkali glass roving. Production of glass roving used glass fiber diameter from 12 ~ 23μm. The number of roving rovin

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
