The main use of fiberglass


The roving is made of parallel filaments or parallel monofilament clusters. Non-twist roving according to glass composition can be divided into: alkali-free glass roving and alkali-free glass roving. The diameter of glass fiber used in the production of roving is from 12. The number of roving is numbered from 150th to No. 9600 (Tex). Roving can be directly used in some composite process molding methods, such as winding, pultrusion process, because of its uniform tension, can also be woven into the roving fabric, in some applications will also be roving further short cut. The roving roving is suitable for the use of the glass fiber reinforced plastic spray molding to have the following performance: Shan good cutting, in the continuous high-speed cutting produced by less electrostatic; Shan roving is cut, the efficiency of dispersing into the original wire is higher, and that is, the splitting rate is high, usually requires more than 90%; Shan short cut of the original silk with excellent laminating, can be covered in all corners of the mold; Shan resin soaked fast, easy to be roller flat and easy to drive off the bubble; the Shan of the original silk tube has good performance, and the roving line density is uniform, Suitable for all kinds of spray gun and fiber conveying system. The jet-free roving is made from many strands of raw silk, each strand contains 200 fiberglass monofilament.
