Abstract: FRP grating covers are available in three common natural resin types: o-benzene, meta-benzene and vinyl. The price is directly proportional to the experience of corrosion resistance, so according to the abstract: FRP grating cover has three common types of natural resin: o-benzene type, meta-benzene type and vinyl type. The price is directly proportional to the experience of corrosion resistance, so there are three common types of natural resins depending on the FRP grating cover: o-benzene type, meta-benzene type and vinyl type. The price is directly proportional to the experience of corrosion resistance, so it is necessary to select the most economical natural resin type according to the corrosion medium used in the background.
(1) O-benzene type: It has ordinary corrosion resistance, can resist atmospheric aging, seawater corrosion, etc., and the temperature is -50~60 °C for a long period of time.
(2) Meta-benzene type (for urban management work): It has good corrosion resistance, can withstand medium and normal liquid concentration, inorganic acid and alkali, various salt and other backgrounds, and the long-term operating temperature is -50~90 °C.
(3) Vinyl type (for chemical use): It has excellent corrosion resistance and can resist acid, alkali, salt, solvent, or acid-base alternating and so on. It has a long-term use temperature of -50~110 °C.
