Many chemical plants, electrolysis plants in smelters, chemical treatment plants in power plants, electroplating plants, storage battery plants, pickling plants in machinery plants, pharmaceutical plants, printing and dyeing plants, salt mines, etc. There are many ditches, most of which are corrosive liquids. Traditional ditches include angle steel, flat iron welded grating, FRP cover, cast iron grating, cement cover, etc.
These materials are not resistant to corrosion and will be damaged in a few years or months. The ditches have a broken appearance and are used. In fact, it can be seen everywhere in life. From community staircase steps to fountain manhole covers, from sewer manhole covers to lawn walkways, they are all application places for glass steel grille manhole covers. Usually glass fiber and resin are selected as basic materials and processed through a series of processes.
Since the FRP grating cover is based on the retaining grating, a layer of FRP cover is added to the outer layer. Due to the characteristics of the FRP cover plate itself, the performance of the FRP cover plate has been improved. Not only the strength, hardness, wear resistance, and slip resistance have been greatly improved, but also the FRP cover plate is more anti-corrosive, which can effectively reduce the corrosion caused by rain, dust, oil stains, and debris, and the service life is more than doubled.
FRP cover plate is a kind of load-bearing plate. The main difference between the FRP pattern cover and the FRP grating is that the former pays more attention to the sealing function, while the latter is relatively more resource-saving. When FRP pattern cover is used as well cover, trench cover and cable trench cover, its main function is to prevent polluting gas from being discharged into the air or polluting source liquid from evaporating, thereby polluting the environment.
FRP cover is a combination of FRP grating and surface pattern cover. Specifically, a 3 mm thick pattern surface is added to the surface of the glass fiber reinforced plastic grille. The pattern surface is made of pure resin, which has the characteristics of corrosion resistance, flame retardant, firmness, non-slip, light weight, convenient installation, maintenance-free, and insulation. FRP cover plates are often used in enclosed areas and sewage treatment facilities to prevent corrosion and gas leakage.
