Characteristics and application of glass fiber cloth

The characteristics of fiberglass cloth

Fiberglass cloth is divided into high-alkali cloth, medium-alkali cloth and non-alkali cloth according to the alkali content. The lower the alkali content, the better the flexural and tensile strength. These types of cloth can be distinguished according to their electrical conductivity. The high-alkali cloth is a conductor and can be used as a wire. The medium-alkali cloth is a semiconductor, and the non-alkali cloth is an insulator. Optical fiber for signal transmission is glass fiber transmission, which belongs to high-alkali cloth, suitable for magnesite cement building materials is medium-alkali cloth, and non-alkali cloth is suitable for circuit boards, electronic grade.

1. It has a good covering function, suitable for various surfaces, effectively covering the defects of new and old walls, and ensuring the uniformity of surface structure and color.
2. Strong tensile strength, effectively prevent the wall from cracking, and reinforce the wall. Cooperated with high-quality paint, the surface does not accumulate static electricity, does not produce dead spots of accumulation, and is easy to clean. Strict surface sizing treatment makes the wall cloth clean and smooth, moisture-proof and mildew-proof, and can prevent the growth of microorganisms or parasites. It is also a kind of reinforcing material.
3. The open spaces of the organizational structure are conducive to the natural diffusion of water vapor and promote the adjustment of the indoor climate.
4. The non-smooth fiberglass fabric surface can reduce noise.
5. Good repeatability, save trouble and labor, easy construction, green and environmental protection, safety and environmental protection, good decorative effect, rich texture.
6. It can be used as reinforcement and drainage in road, water conservancy, environmental protection and other projects.

In what fields can fiberglass cloth be applied?

1. Electronic and electrical fields
Because fiberglass woven roving has good electrical insulation and corrosion resistance, it can be used in the electrical and electronic fields. For example, fiberglass cloth can be used as electrical cover materials, including electrical switch boxes, electrical wiring boxes, instrument panel covers, etc. It can also be used as electrical components and electrical component materials, including insulators, insulation tools, motor end covers, etc. In addition, it can also be used as a power transmission material, including composite cable brackets, cable trench brackets, etc.
2. Ship field
Fiberglass cloth has strong corrosion resistance, and is very light in weight, which has a significant reinforcing effect. Therefore, fiberglass cloth is now widely used in the field of shipbuilding, such as the hull and deck of yachts, etc. After using fiberglass cloth in these places, its strength can be effectively enhanced, and it is less likely to be corroded when used in seawater.
3. Wind energy equipment field
Nature bestows us with a lot of precious energy, and wind energy is one of them. It is non-polluting and sustainable. Therefore, wind power generation is now regarded as a way to develop new energy. Because of its superior reinforcement effect, light volume and many other characteristics, it has become a good material for manufacturing FRP blades and unit covers and is widely used in wind energy equipment.

In addition to being used in the fields of electronics, ships, and wind energy equipment, fiberglass reinforced cloth is also used in many fields such as aerospace, architectural decoration, and chemical engineering. However, in order to allow it to better play its advantages and functions, it is necessary to know more about how to use fiberglass cloth and use the correct method to use it.

How to improve the hardness of fiberglass cloth?

Fiberglass mesh is a commonly used thermal insulation and reinforcement material for exterior walls of modern buildings. Breaking strength and alkali resistance are important properties of constant glass fiber mesh. The breaking strength of fiberglass cloth is closely related to the quantity or weight of glass. Domestic product standards require that the weight of glass fiber mesh cloth per square meter should be more than 160g (the mainstream in the market is 120g, and the cost is low).

I n the process of using glass fiber mesh cloth, it is necessary to improve the breaking force standard. Especially a high cement content, high cement strength grade polymer cement plaster mortar. The damage of these things to the glass fiber mesh is not only chemical corrosion, but also crystallization pressure corrosion of calcium hydroxide and calcium sulfoaluminate. At the same time, the high water absorption of mineral materials also has an adverse effect on glass fiber mesh. Experiments have shown that the strength of glass fiber mesh will lose about 30% after soaking in distilled water. Glass fiber alkali-free cloth, also known as E fiberglass cloth, refers to glass fiber with low alkali metal oxide content. The specific content of alkali metal oxides is currently no more than 0.8% in China and around 1% in foreign countries. Do you know how high the temperature the glass fiber non-alkali cloth can withstand?

Glass fiber alkali-free cloth is suitable for industries such as electromechanical, chemical, pipeline, ship, wire and cable. Glass fiber non-alkali cloth has high strength, good insulation effect, and can withstand high temperature of 550-1000.

Glass fiber alkali-free cloth is a very good substitute for metal materials, mainly used as electrical insulation materials, reinforcement materials for FRP and tire cords. For composite cable holders.

Cement-free pure polymer plastering mortar has no alkali corrosion and low water absorption, and the glass fiber mesh cloth can function normally in it for a long time, which is undoubtedly very safe for the long-term crack resistance of the protective surface.
