Glass fiber cloth is made from glass pellets or waste glass through high-temperature melting, drawing, winding, and weaving. The diameter of a single filament ranges from a few microns to over 20 microns, equivalent to 1/20-1/5 the diameter of a human hair. Each strand of fiber is composed of hundreds or even thousands of individual filaments.
What are the characteristics of glass fiber cloth?
1. It can be used in temperatures ranging from -196°C to 300°C, and is weather-resistant.
2. It is non-adhesive and does not easily adhere to anything.
3. It is chemically resistant, including strong acids, alkalis, aqua regia, and various organic solvents.
4. It has a low coefficient of friction, making it an excellent choice for oil-free self-lubrication.
5. It has a light transmittance of 6-13%.
6. It offers high insulation, UV protection, and anti-static properties.
7. It is strong and has excellent mechanical properties. 8. Chemical Resistance
The Function of Fiberglass Cloth
Some people ask what the function of fiberglass cloth is. It's like thinking of a house constructed of cement and steel bars. Fiberglass cloth acts like steel bars, reinforcing the fiberglass reinforced plastic.
What applications are fiberglass cloth used for?
Fiberglass cloth is primarily used in hand lay-up processes. Fiberglass-reinforced woven fabric is primarily used in ship hulls, storage tanks, cooling towers, ships, vehicles, tanks, and building structures. In industry, fiberglass cloth is primarily used for thermal insulation, fire protection, and flame retardancy. When exposed to flames, this material absorbs significant heat, preventing flames from passing through and insulating the air.
Fiberglass Cloth Classification
1. By Composition: Mainly medium-alkali, alkali-free, and high-alkali (based on the alkali metal oxide content of the glass fiber). There are also other classifications based on composition, but the variety is too numerous to list here.
2. By Manufacturing Process: Crucible drawing and tank kiln drawing.
3. By Variety: Ply yarn, direct yarn, spray yarn, etc. In addition, fiberglass fabrics are categorized by single fiber diameter, TEX number, twist, and sizing type. The classification of fiberglass cloth is similar to that of fiber yarn. In addition to the above, it also includes weave, weight, and width.
What is the difference between fiberglass cloth and glass?
The main material differences between fiberglass cloth and glass are not significant. The main difference is the different material properties required during production, which leads to some differences in the formulation. Flat glass contains approximately 70-75% silica, while fiberglass generally contains less than 60%.
Glass is an inorganic material melted at high temperatures (above 800°C; household glass is generally melted at 1100°C). Below its softening point, it undergoes no chemical changes. Above this point, it simply softens, melts, or decomposes, but does not burn.
Fiberglass cloth is made by drawing glass into extremely fine filaments, which are then very flexible. The filaments are spun into yarn and then woven on a loom to create fiberglass cloth. Because glass fibers are extremely fine and have a large surface area per unit mass, their heat resistance is reduced. Just as a candle can melt a thin copper wire, it's possible to see the flames.
However, glass doesn't burn. The visible flames are actually caused by the resin coating or impurities adhering to the fiberglass cloth, which improves its performance. Pure fiberglass cloth, or cloth coated with high-temperature-resistant coatings, can be made into products such as fire-resistant clothing, gloves, and blankets. However, if it comes into direct contact with the skin, the broken fibers can cause irritation and itching.
What's the difference between fiberglass cloth and fiberglass reinforced plastic (FRP)?
Fiberglass cloth is the material used to make FRP products. FRP is essentially a composite plastic made by combining glass fibers with resins, curing agents, accelerators, and other materials through various processes, then curing.
What should I do if I accidentally get fiberglass cloth on my clothes or body?
Generally, the diameter of conventional fiberglass filaments is between 9 and 13 microns. Floating particles in fiberglass below 6 microns can enter the lungs and cause respiratory problems, so be especially careful. Fiberglass below 6 microns is generally imported. Wearing a professional mask is mandatory during production operations. Frequent contact can cause inhalation into the lungs, leading to pneumoconiosis.
If fiberglass gets on your body, those with sensitive skin may experience allergic reactions and itching, but this is generally not a serious problem. Those with sensitive skin may develop small blisters, which are an allergic reaction and can be cured with anti-allergy medication.
