Cov yam ntxwv ntawm cov kav dej ncaj seam steel: Cov kav dej ncaj seam steel feem ntau xa mus rau kev siv cov txheej txheem tshwj xeeb los tiv thaiv corrosion ntawm cov kav hlau zoo tib yam, kom cov kav hlau steel muaj peev xwm tiv thaiv corrosion zoo heev. Lawv feem ntau yog siv rau waterproofing, anti-xeb, anti-acid thiab alkali, anti-oxidation, thiab lwm yam yam ntxwv. Lub hauv paus hlau txheej txheem rau ncaj seam anti-corrosion steel kav muaj xws li submerged arc welded ncaj seam steel kav thiab high-frequency ncaj seam steel kav. Qhov txoj kab uas hla ntawm kev tiv thaiv corrosion submerged arc welded ncaj seam steel yeeb nkab yog siab tshaj 325, thiab txoj kab uas hla ntawm cov anti-corrosion high-frequency ncaj seam steel yeeb nkab yog qis dua 426. Kev ntsuas los tiv thaiv corrosion yog siv rau sab hauv thiab sab nrauv phab ntsa. ntawm cov yeeb nkab steel raws li kev xav tau sib txawv thiab kev thov ib puag ncig. Feem ntau siv xws li epoxy thee pitch anti-corrosion steel kav, polyurethane anti-corrosion coatings, IPN8710 dej diversion anti-corrosion coatings, anti-corrosion polymer coatings, thiab anti-corrosion steel yeeb nkab sab hauv phab ntsa cement. Mortar anti-corrosion, thiab lwm yam. Anti-corrosion steel kav yog tsuas yog siv nyob rau hauv engineering teb nrog tshwj xeeb yuav tsum tau los yog hnyav ib puag ncig. Tom qab kev kho mob los tiv thaiv corrosion, txoj kab ncaj nraim los tiv thaiv corrosion steel yeeb nkab tuaj yeem tiv taus corrosion thiab muaj cov yam ntxwv ntawm cov dej tsis zoo, tiv thaiv xeb, tiv thaiv acid thiab alkali, tiv thaiv oxidation, thiab lwm yam khoom.
