Glass fiber
Glass fiber is a kind of inorganic nonmetal material with excellent performance. English name is: Fiber glass. It is produced by high temperature melting, wire drawing, winding and weaving process with the raw materials of glass balls or waste glass. Glass fiber monofilament diameter ranges from a few microns to twenty micron, the equivalent of a hair 1\20-1\5. Each bundle of fibers are hundreds or even thousands of root root filaments, usually treated as a reinforcing material of complex materials, electrical insulating materials and thermal insulation materials, circuit board, etc. and widely used in various fields of the national economy. Properties of glass fiber: The general concept of glass is hard and brittle objects, but it is not suitable for timber structure as its thread. Strength is greatly increased and it is more flexible, so it can finally become excellent timber structure after shaped by the resin. For glass fiber, with diameter smaller, the intensity increases. As a reinforcing material, glass fiber has the following characteristics. These characteristics make the use of glass fibers more broadly than other species of fibers. Its strength is greatly increased and it is more flexible. With good rigidity, it could absorb more impact energy.
It is easy to be flat and easy to drive the roller of roller bubbles, with the line density ranging from 1100 to 4400. The fabric, made by very fine fiber,can be divided into several types. E- glass is also known as alkali free glass. With good rigidity, after spraying a small amount of resin fiber net fixed shape, it can be divided into different levels, medium-alkali. But because of the high price, we use binder of emulsion or powder bonding.
After heating and solidating, it becomes chopped strand felt. (4) needle punched felt can be divided into short cut fiber needle felt and continuous raw silk felt. Along the width of the direction, the area and quality is uniform. (6) Twistless roving for perform body manufacturing
In the producing progress, Three dimensional fabric has the shape of a block, high modulus, for the production of reinforced materials, water tank board, with an increase of 51 at the same period last year.
