The characteristics of the FRP grille cover; resistant to corrosion by a variety of chemical media, never rust, long service life, and maintenance-free; flame-retardant, insulating, non-magnetic, and slightly elastic, which can reduce personnel fatigue and improve work Efficiency; light weight, high strength, easy to cut and install, strong designability, flexible and diverse dimensions, and stable dimensions.
According to the current market, along with economic development and technological progress, some new products continue to come back, and old products continue to withdraw.
As a new composite material, FRP grating has slowly come back, but correspondingly, its substitutes such as pp board, ppr board, pvc board and other plastic materials are gradually reduced. We believe that their main raw materials
What are the two main raw materials that determine the quality of FRP gratings?
First, glass fiber: can be divided into three types of glass fibers: high alkali, medium alkali, and alkali-free. Generally, the choice can be determined according to the corrosiveness of the manufactured product in the use environment. It is recommended that everyone use alkali-free glass fiber to be more assured.
The second type, resin: can be divided into phenolic type, vinyl type, o-phthalic type, isophthalic type and other four commonly used unsaturated resins. There are many kinds of it, and there are many characteristics at the same time. Including its corrosiveness, color, acid and alkali resistance, flame retardancy, etc. are different. Therefore, it is recommended that when you choose FRP grating in the future, you should decide to buy according to these two major indicators.
