FRP grating has very superior corrosion performance in many gas and liquid media such as acid resistance, alkali resistance and salt, and has incomparable superiority in the field of anti-corrosion. According to the requirements of actual use occasions, o-phthalic, isophthalic, and vinyl resins can be economically selected as the matrix material. Among them, there is a product called FRP grille cover. What should workers pay attention to when installing this product?
When installing, you can choose to combine two or four glass fiber plastic grille covers, with a tree-shaped hole in the middle, and the grille and the grille are connected by fasteners or screws, which is simple to install and easy to maintain. There is a relative gap between the edge of the FRP grille cover and the pool wall. Note that the tree hole in the middle is slightly larger, after all, the tree still needs to grow. The bottom of the FRP grille cover plate should be leveled. As the new tree hole sinks, check the filling in time to prevent the lid from sagging. After installation, please pay attention to be parallel to the sidewalk ground to prevent pedestrians from tripping while walking. The FRP grille cover is not easy to be bent irreversibly. In addition, the quality of FRP is relatively light. The quality of the grille made of this material is about 1/4 of that of the original steel grille, which greatly reduces the cost of the sewage treatment system.
Although economic development is important, the environment has gradually become less important in the subsequent development. In this case, the current development cannot be connected. Therefore, we must protect various environments. In sewage treatment, materials such as glass fiber reinforced plastic grille should be selected. More and more FRP gratings are accepted by the building materials market, and the number of customers is also increasing.
