After the FRP gas collecting hood is "capped", the sewage entering the lagoon will not only infiltrate the groundwater, but also the odor of the odor will no longer volatilize and pollute the environment. The negative impact of sewage treatment on the surrounding environment is thus minimized. The technique of covering and deodorizing the cover film has been generally used only for leachate treatment in landfills, and it is just right to use it in urban sewage treatment.
At present, FRP gas hoods are mainly divided into two categories, one is the traditional sump cover, which is mainly made of metal. Since the effluent pool contains a lot of corrosive factors, the metal lag pool cover needs to pass corresponding before use. Plating or painting treatment. The disadvantage is that it is easily corroded and the use time is not long enough. Once it is corroded, the entire operating platform needs to be removed.
The second type of sump cover is a composite glass reinforced plastic cover. It is made of glass fiber yarn and resin. Its advantages can be applied to different harsh corrosive environments. The specific materials can be selected according to the specific environment and corrosive strength. material. In addition to acid and alkali resistance, the FRP cover also has this high enough strength and load carrying capacity. In addition, its cost of construction is low and its economic efficiency is high.
FRP gas hoods have gradually dominated the market in recent years, which is inseparable from its overwhelming advantages.

Crane Sole Plate is used under crane rail. The primary function of soleplates is to provide rails with a flat and smooth resting surface. Soleplates are used to support the rails in situations where concrete is not strong enough to support crane rails. Depending on the load and the type of rail, soleplates can be made continuous or individual.
