What kind of FRP tanks durable

Outside FRP tanks and tank bottom base surface in direct contact with the use of impressed current cathodic protection coating for joint protection. This environment requires coating has good water resistance and durability, the simultaneous use of cathodic protection, it requires good cathodic disbondment performance. Considering the cost and technology maturation, at the site recommended epoxy coatings and polyurethane coatings. Corrosive environment for a typical industrial atmospheric corrosion environments. Atmospheric corrosion in industrial environments, the requirements of the coating system has the following main points: 1) good rust resistance; 2) good adhesion, impact resistance and other mechanical properties; 3) Paul Light excellent UV resistance color retention; good 4) construction performance, can be well adapted to site conditions; 5) The technology is mature and reliable, cost-effective. Currently the most widely used coating scheme are: epoxy zinc-rich primer / epoxy intermediate coat of iron / acrylic polyurethane topcoat. Crude oil is usually the most severe corrosion FRP tanks site. Corrosive water is mainly crude oil deposits, its complex composition, corrosion characteristics of the parts of the electrochemical corrosion and severe localized corrosion and pitting tendency, easy to produce corrosion perforation. This recommended weight epoxy anti-corrosion coating with sacrificial anode cathodic protection. Tank floor may be an aqueous lithium silicate zinc-rich coating can be formed on the tank bottom cathodic protection, and environmental protection, construction of simple features.
