As the FRP grille market is very hot now, it is inevitable that there are many manufacturers in the market who are doing fish-eyes for profit. Many manufacturers adopt some relatively inferior original materials to make them shoddy in order to increase their capital. However, as a consumer, I don't know the tricks. I will tell you how to distinguish the quality of the steel grille tomorrow.
Original information: Many producers are not clear about the selection of original materials for FRP gratings. The main raw materials of FRP grating are resin and FRP fiber. The filler is calcium powder, and it is generally configured in a ratio of about 1:1:1.
A good resin is generally unsaturated orthophthalic resin 196, and the glass fiber reinforced plastic grille with this resin is generally flat and lubricated. If inferior resin is used, the product will be turbid and porous, and the most important thing is easy to break, poor strength and toughness.
Another is the comparison of the finished product: a good glass fiber reinforced plastic grille has no obvious cracks in appearance, the pores are very sandy, the color is relatively pure, and the application life is relatively long. However, inferior products have obvious cracks in the appearance, many pores, poor color, and of course the life span is shorter.
At present, the market of FRP gratings is relatively messy, so the above two comparatively simple judgment methods are especially recommended for you. This will definitely help you to buy FRP grating products. In fact, theory is the only criterion for testing the true meaning. Those inferior FRP gratings cannot withstand the test of theory and will definitely reveal its loopholes in the end.
