What is fiberglass cloth made of?

What are the characteristics of fiberglass cloth?
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. Fiberglass cloth has good mechanical properties.
8. Drug resistance

What are the classifications of fiberglass cloth?
1. According to ingredients: 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 roving, direct roving, spray up roving, 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.

What is the difference between the material of fiberglass cloth and glass?
  There is little difference between the main materials of Fiberglass Fabric and glass, mainly due to the different material requirements during production, so there are some differences in the formula. The silica content of flat glass is about 70-75%, and the silica content of glass fiber is generally below 60%.
Glass is an inorganic material melted at high temperature (above 800 degrees, daily glass is generally melted at 1100 degrees), and no chemical changes will occur below the softening point temperature. Above the softening point temperature, it will only soften, melt or decompose, and will not burn.

  Hebei Yuniu Fiberglass Manufacturing Co., Ltd. produces glass fiber cloth by drawing glass into very fine glass filaments, and the glass filaments at this time have good flexibility. The glass fiber is spun into yarn, and then woven into glass fiber cloth through a loom. Because the glass filament is extremely thin and the surface area per unit mass is extremely large, the temperature resistance performance is reduced. It's like melting a thin copper wire with a candle.
But glass doesn't burn. The burning we can see is actually the resin material coated on the surface of the glass fiber cloth, or the attached impurities to improve the performance of the glass fiber cloth. After pure glass fiber cloth or some high temperature resistant coatings, it can be used to make products such as refractory clothing, refractory gloves, and refractory blankets. However, if it is in direct contact with the skin, the broken fibers will irritate the skin to a certain extent and it will itch.
