When buying a FRP grating, you can't be greedy and cheap. You should buy it according to your own actual situation. You must have strict requirements on product quality. Don't think it can be used. The following small series will tell you about several common mistakes in the purchase of FRP grating: the main components of FRP grating are resin, glass fiber, filler (aluminum powder or calcium powder), color paste, trace reagent (curing agent) , strengthening agents, etc.).
First, the heavier the FRP grating, the better? This is not the case, because the proportion of the FRP grating is well-founded, then the weight of the product will definitely have a reference standard, if the weight of the grille greatly exceeds The theoretical weight value, then the BV and resin content in the FRP grid will be reduced, so that the strength of the grid plate produced will be reduced, the corrosion resistance, aging resistance and other properties will be deteriorated, and the service life will be greatly reduced. The appearance of the grid plate does not look glossy, and there may be a large number of white spots.
1. When cutting the FRP grating, there are many small holes inside. This does not mean that the quality of the FRP grating is not good. In fact, if the inside is flat after cutting, there is no porosity, it means that it is being produced. The calcium powder added during the process of the grid is relatively large, which affects the performance of the FRP grating, and the phenomenon of falling slag is more serious. Third, the more quality of the FRP grating fiber layer, the better, this statement is wrong. Because the fiber yarn plays a role of connecting and carrying, there must be a reasonable proportion, generally 7 to 8 layers, too much will be self-defeating. The fiber layer is relatively low in price relative to the resin. In other words, the more fiber layers are pulled in, the lower the cost of the FRP grating affects the stiffness and toughness of the FRP grating. In short, when using a FRP grating, it is not as heavy as possible, nor is the fiber layer more, the better, must have a reasonable ratio to produce a durable grille.
The above is a few misunderstandings about the purchase of FRP gratings, which I hope will help you.
