Liphaephe tse nang le Coatings for Anti-corrossion
Selelekela sa Lihlahisoa
Maemo: Litekanyetso tsa liphaephe tse thibelang ho bola li behiloe ke mekhatlo e kang American Society for Testing and Materials (ASTM), International Organization for Standardization (ISO) le National Society of Corrosion Engineers (NACE). Litekanyetso tsena li totobatsa litlhoko tsa lisebelisoa tsa ho roala, mekhoa ea kopo, mekhoa ea liteko le litekanyetso tsa ts'ebetso.
Likarolo tse ipapisitseng le kalafo ea holim'a metsi: Liphaephe tse nang le li-anti-corrosion li ka aroloa ho latela mofuta oa ho roala o sebelisitsoeng. Likarolo tse tloaelehileng li kenyelletsa: Fused Bonded Epoxy (FBE) Coating Polyethylene (PE) kapa polypropylene (PP) coating Asphalt kapa asphalt barbotage Zinc e ruileng pente Polyurethane barbotage Leshala tar enamel barbotage.
Lisebelisoa: Liphaephe tse nang le liphahlo tse thibelang kutu li sebelisoa haholo liindastering tse fapaneng, ho kenyeletsoa:Oli le Khase: Lipeipi tse sebelisetsoang ho tsamaisa oli e tala, khase ea tlhaho le lihlahisoa tsa peterole Metsi le metsi a litšila: bakeng sa metsi a ka tlas'a lefatše le likhoerekhoere. le offshore: bakeng sa lipeipi tse ka tlas'a maoatle le meaho ea maoatle Infrastructure: Bakeng sa tšebeliso ea marokho, boema-kepe le meaho e meng e pepesehetseng maemo a thata a tikoloho Liphaephe tsena li bohlokoa bakeng sa ho boloka bots'epehi le nako e telele ea lits'ebetso tsa mantlha tsa ts'ebetso le lits'ebetso tsa indasteri, haholo tikolohong e thata kapa e senyang.
