1. Introduction of glass fiber yarn:

Raw materials are processed by high temperature melting, drawing, winding, weaving and so on. After the formation of various products, glass fiber monofilament diameter from a few microns to more than twenty meters microns, equivalent to a hair of 1/20-1/5, each bundle of fiber precursors have hundreds or even thousands of monofilaments, usually used as reinforcing materials in composite materials, electrical insulation materials, insulation materials, circuit substrates, etc., widely. It is applied to all fields of national economy.

Two, glass fiber yarn characteristics:

The general idea of glass is that hard and fragile objects are not suitable for use as structural materials, but when they are drawn into silk, their strength increases greatly and they are flexible, so they can finally become excellent structural materials with resin shape. Glass fiber decreases with its diameter and its strength increases.

High. As a reinforcing material, fiberglass has the following characteristics, which make the use of fiberglass far wider than other kinds of fibers, and the development speed is also leading. Its characteristics are as follows:

(1) high tensile strength and small elongation (3%).

(2) high elasticity coefficient and good rigidity.

(3) the elongation within the elastic limit is large and the tensile strength is high, so the impact energy is large.

(4) inorganic fibers, which are non flammable and highly resistant to chemicals.

(5) water absorption is small.

(6) the scale stability and heat resistance are all good.

(7) good workability, and can be made into different forms of stock, bundle, felt and weaving.

(8) transparency can be transmitted through light.

(9) good combination with resins and adhesives.

(10) the price is cheap.

Three. The use of glass fiber yarns after preparation:

1. It can be made into engineering plastics, high-temperature heat-resistant fire-proof cloth, and used for safety protection of equipment, instruments and instruments under adverse working conditions such as open fire, high-temperature splashing, dust and thermal radiation in industrial high-temperature areas.

2. It can be made into fiberglass sleeve, which can be used for safety protection of wire, cable, hose and tubing under adverse conditions such as open fire, high temperature splash, dust and thermal radiation in industrial high temperature zone.

3. High-temperature sleeve can be made with silicone rubber. It can be used for safety protection of wire, cable, hose and tubing in industrial high-temperature zone under adverse conditions such as open fire, high-temperature splashing, dust, water vapor, oil pollution, heat radiation, etc.

4. Compound with silica gel to make high-temperature heat-resistant cloth, which can be used for safety protection of equipment, instruments and instruments under adverse working conditions such as open fire, high-temperature splashing, dust, water vapor, oil pollution and thermal radiation in industrial high-temperature areas.
