Glass fiber (formerly known as: glass fiber) is an inorganic non-metallic material with excellent performance. Wear resistance is poor. Glass fibers are usually used as reinforcing materials in composite materials, electrical insulating materials and thermal insulation materials, circuit substrates and other fields of the national economy.
Features
1. It is used for low temperature -196 °C and high temperature between 300 °C and has weather resistance.
2. Non-adhesive, not easy to adhere to any substance.
3. It is resistant to chemical corrosion and corrosion of strong acid, strong alkali, aqua regia and various organic solvents.
4. Low friction coefficient, it is the best choice for oil-free self-lubrication.
5. The transmittance is 6-13%.
6, with high insulation performance, anti-ultraviolet, anti-static.
7. High strength. Has good mechanical properties.
8. Drug resistance.
Application
Glass fiber cloth is mostly used in the hand lay-up process, and the glass fiber reinforced material square cloth is mainly used in ship hulls, storage tanks, cooling towers, ships, vehicles, tanks, and building structural materials. Fiberglass cloth is mainly used in industry for: heat insulation, fire prevention and flame retardant. The material absorbs a lot of heat when it is burned by a flame and can prevent the flame from passing through and isolate the air. It is recommended to use Shenzhen Puyun PY-H600D pneumatic quantitative sampler and PY-E627 precision electronic analytical balance for glass fiber book weight determination.
Classification
1. According to the composition: mainly medium alkali, non-alkali, high alkali (to classify the composition of alkali metal oxides in glass fiber), of course, there are also classifications by other components, but there are too many varieties, not one by one. enumerate.
2. According to the manufacturing process: crucible wire drawing and pool kiln wire drawing.
3. According to the variety: there are plied yarn, direct yarn, jet yarn, etc.
In addition, it is distinguished by single fiber diameter, TEX number, twist, and type of sizing agent.
The classification of glass fiber cloth is the same as the classification of fiber yarn. In addition to the above, it also includes: weaving method, gram weight, width, etc.
