The raw materials used in the FRP grating are resin, fiberglass fiber filaments, and calcium powder as the filler in a ratio of 1:1:1. The high-quality FRP grating is made of high-quality resin: unsaturated phthalic resin 196, colorless and transparent. Low viscosity, low exotherm, low shrinkage, high-speed curing, high-speed compatibility, bright gloss. The produced FRP grating is flat and smooth, with good gloss, high strength and certain toughness. If you use inferior resin, it will be completely opposite. Inferior resin is turbid, high viscosity, high exotherm, high shrinkage, relatively slow curing, and poor compatibility. The produced glass fiber reinforced plastic grid has many pores, is easy to break, and has poor strength. Toughness is not good.
In the glass fiber reinforced plastic grid, the toughness of the grid can be enhanced is the fiberglass fiber wire. High-quality fiberglass fiber such as alkali-free fiberglass fiber has a certain toughness, chemical stability, good weather resistance, almost no water absorption and fire, and its high strength can also be used as tire cord. Huaxian Stone Company's FRP filaments are laid in 8-9 layers, so the strength of the product is guaranteed. The FRP fiber yarn used by some manufacturers is high-alkali yarn as an alkali-free yarn, which has low strength and poor water and alkali resistance.
The filler of the FRP grid is calcium powder or aluminum powder. The high-quality filler is fine and white in nature, has flame retardancy, and is completely fused with the resin. The produced board is beautiful in color, good in transparency, and strong in toughness. On the contrary, the inferior filler powder is rough and dull, not flame-retardant, and the produced board has no gloss, and is relatively brittle and tough.
