Fiberglass is an inorganic non-metallic material with excellent properties. English original name: glass fiber. The ingredients are silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, etc. It uses glass balls or waste glass as raw materials through high temperature melting, wire drawing, winding, weaving and other processes. Finally, various products are formed. The diameter of glass fiber monofilament ranges from a few microns to more than 20 microns, which is equivalent to 1/20-1/5 of a hair. It is composed of thousands of monofilaments and is usually used as a reinforcing material in composite materials, electrical insulating materials and thermal insulation materials, circuit substrates, etc.
The quality of glass fiber is distinguished from several product characteristics:
Glass is generally considered to be a hard and fragile object, and it is not suitable for use as a structural material. However, if it is drawn into silk, its strength will be greatly increased and it has flexibility. Therefore, it can finally become an excellent structural material after being given a shape with resin. Glass fibers increase in strength as their diameter decreases. As a reinforcing material, glass fiber has the following characteristics:
(1) High tensile strength and small elongation (3%).
(2) High elastic coefficient and good rigidity.
(3) The amount of elongation within the elastic limit is large and the tensile strength is high, so the absorption of impact energy is large.
(4) It is an inorganic fiber, which is non-flammable and has good chemical resistance.
(5) Low water absorption.
(6) The dimensional stability and heat resistance are all good.
(7) Transparent and can transmit light.
How does quality affect E-glass fiber roving?
We all know that when buying E-glass fiber roving, we need to buy E-glass fiber roving of good quality, but do you know how the quality of E-glass fiber roving affects E-glass fiber roving?
In fact, the quality of E-glass fiber roving has obvious influence on E-glass fiber roving. For example, the service life of E-glass fiber roving is closely related to the quality of E-glass fiber roving. In addition, the quality also affects the use of E-glass fiber roving industry.
When we choose to buy alkali-free glass fiber roving, we should try our best not to buy cheap products, and we must purchase alkali-free glass fiber roving according to the quality of alkali-free glass fiber roving. In line with the concept of professionalism, innovation, integrity and customer-oriented service attitude, CQDJ Comapan continues to improve and strive for development, with the goal of producing high-quality equipment, creating a glass fiber brand enterprise, and joining hands with domestic and foreign counterparts to create a better tomorrow. We look forward to sincerely cooperating with you and jointly contributing to the development of my country's glass fiber material industry.
How to distinguish the quality of alkali-free glass fiber roving?
At present, the use of E-glass fiber roving is more and more, so how to distinguish the quality of E-glass fiber roving when purchasing it? The following is an introduction by the alkali-free glass fiber roving manufacturer. I hope the following suggestions will be helpful to you.
1. It is known from the alkali-free glass fiber roving manufacturer that the alkali-free glass fiber roving with better quality has a clean surface, the warp and weft lines of the grid are even and straight, the toughness is better, and the mesh is relatively uniform. On the other hand, the alkali-free glass fiber roving with poor quality has uneven grids and poor toughness.
2. The alkali-free glass fiber roving with better quality is glossy and uniform in color, while the alkali-free glass fiber roving with poor quality is not only thorny to touch, but also dark and turbid in color.
3.The quality of E-glass fiber roving can also be judged by stretching it. E-glass fiber roving with good quality are not easily deformed, and can be recovered by stretching, while E-glass fiber roving with poor quality are difficult to recover from their deformation after being stretched, which will affect normal use.
Briefly describe the application fields of alkali-free glass fiber roving
Due to the special requirements for materials in aerospace, military and other fields, the use of E-glass fiber roving is more common, because E-glass fiber roving has the characteristics of light weight, high strength, good impact resistance and flame retardancy.
The alkali-free glass fiber roving manufacturer said that the alkali-free glass fiber roving has good dimensional properties and good reinforcement performance. Compared with steel, concrete and other materials, it has the characteristics of light weight and corrosion resistance, which makes the alkali-free glass fiber roving. roving has become an ideal material for manufacturing infrastructure such as bridges, docks, highway pavements, trestle bridges, waterfront buildings, and pipelines.
The application of E-glass fiber roving in electrical and electronic fields mainly utilizes its electrical insulation, corrosion resistance and other characteristics. The applications of E-glass fiber roving in the field of electrical and electronic are mainly electrical switch boxes, electrical wiring boxes, instrument panel covers, insulators, insulating tools, motor end covers, etc., transmission lines include composite cable brackets, cable trench brackets, etc.
