的优劣 Teach you how to distinguish the advantages and disadvantages of FRP grille
At present, the domestic FRP grid market is relatively hot. There is no shortage of fish-eye-mixed bead manufacturers in the hot market. In order to reduce costs, many manufacturers use some relatively inferior raw materials to recharge. However, as a consumer, I do n’t know what ’s so messy. How can I tell the quality of the steel grille?
In fact, when we judge the quality of a product, we must first judge from its raw materials, and then judge the product.
Raw materials: Many consumers are not clear about the selection of raw materials for FRP gratings. The main raw materials of FRP grid are resin and FRP fiber. The filling material is calcium powder, and is generally configured according to a ratio of about 1: 1: 1.
A good resin is generally unsaturated phthalate resin 196. The FRP grids produced by this resin are generally smooth and smooth. If you use inferior resin, the product will be more turbid and porous, the most important thing is easy to break, poor strength and toughness.
Another is the comparison of the finished product: from the appearance of a good FRP grille, there are no obvious cracks, the pores are sandy, the color is more pure, and the service life is longer. However, inferior products have obvious cracks in the appearance, many pores, and poor color, and the life is of course shorter.
