I. Overview of chopped glass fiber products:
Chopped glass fiber: the precursor stretched with special size is chopped online by wet method. Chopped glass fiber is cut from glass fiber filament with a chopping machine, and its length is generally in mm, and its basic properties mainly depend on the properties of its raw material-glass fiber filament. Because the appearance is a certain length of fluff, compared with longer filaments, chopped filaments have the advantages of uniform dispersion, diverse feeding methods and simple process in industrial use, so they can be applied to fields where filaments are not suitable.
Second, the product parameters of chopped glass fiber:
R2O content: ≤0.80%
Coupling agent type: silane
Applicable resins: PA, PP, PBT, ABS, BMC, etc.
Fiber diameter: 9-13μ m.
Moisture content: ≤0. 1%
Third, the function of chopped glass fiber products
1. After glass fiber chopped filaments are added to various plastics, resins, automobile parts, BMC, SMC, friction materials, gypsum boards, glass fiber reinforced plastics, composite materials, electrical appliances and other products or construction projects, they can obviously play a role in strengthening, cracking resistance and wear resistance.
2. Mixing chopped glass fiber into cement and concrete can prevent the generation and propagation of cracks, improve the impermeability and freeze-thaw resistance of concrete, improve the impact toughness of concrete and improve the durability of concrete.
3. Adding glass fiber filaments into building materials such as reservoirs, roofs and floors, swimming pools, septic tanks and sewage treatment tanks can obviously improve their strength and service life.
