The glass fiber roving produced by Hebei Yuniu Fiberglass Manufacturing Co., Ltd. is divided according to the production process, such as glass fiber direct yarn drawing, which belongs to the winding forming process, and can also be collectively called fiberglass roving, which improves the utilization rate of sizing agent. , After reducing the moisture content of the wet yarn, the drawing tension will increase, resulting in the breakage of the end fibers and the wool yarn.
1. Characteristics of fiberglass roving
2. fiberglass roving is an inorganic non-metallic material with excellent performance, which is characterized by good insulation, strong heat resistance, good corrosion resistance, high mechanical strength, good bundling and tape-forming properties, and can be combined with a variety of resins. High capacity, fast infiltration speed, fast infiltration in resin, good moisture absorption resistance, less hairiness, and good mechanical properties.
Second, the use of fiberglass roving
Glass fiber is usually used as reinforcing material in composite materials, electrical insulating material and thermal insulation material, circuit substrate and other fields of the national economy. The fiberglass roving is mainly used as electrical insulating material, industrial filter material, anti-corrosion, moisture-proof, heat-insulating, sound-insulating, shock-absorbing material, and can also be used as reinforcing material to make reinforced plastic or reinforced rubber, reinforced gypsum and reinforced cement, etc. product.
Glass is a hard and brittle object and is not suitable as a structural material, but if it is drawn into filaments, its strength will be greatly increased and the glass fiber has the 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.
