kev tiv thaiv kev txi yog txoj kev tiv thaiv corrosionnyob rau hauv uas cov hlau siv hluav taws xob ntau dua yog hluav taws xob txuas rau cov hlau tsis tshua muaj zog. … Qhov no thim rov qab cov hlau tiv thaiv rov qab mus rau nws daim ntawv qub, thiab yog li tiv thaiv nws los ntawm corroding.

Yuav siv li cas rau kev tiv thaiv kev txi?

Kev tiv thaiv kev txi yog kev tiv thaiv hlau lossis hlau tiv thaiv corrosion los ntawm kev siv cov hlau ntau dua. Cov zinc lossis magnesium alloy yog txuas rau lub cev thiab cov kav dej. Cov hlau tiv thaiv dhau los ua cov cathode thiab tsis corrode.

Kev tiv thaiv kev txi yog dab tsi?

Kev tiv thaiv hlau lossis hlau tiv thaiv corrosion los ntawm kev siv cov hlau ntau dua. Ib hom ntawv yog galvanizing, nyob rau hauv uas hlau nto yog coated nrog ib txheej ntawm zinc.

Zaj kev tiv thaiv kev txi yog dab tsi?

Zinc corrodes nyob rau hauv kev nyiam rau hlau thiab txi nws tus kheej los tiv thaiv cov hlau, yog li kub dip galvanizing yuav muab kev tiv thaiv kev txi no. Cov khoom siv corrosion los ntawm zinc yog tso rau ntawm cov hlau resealing nws los ntawm huab cua thiab yog li ntawd nres corrosion.

Ib qho piv txwv ntawm kev txi txiab txiab dab tsi?

Cov hlau fij tseg tau dav siv los tiv thaiv lwm cov hlau los ntawm kev xeb: piv txwv li hauv galvanised steel Ntau cov khoom hlau yog coated nrog txheej zinc, uas yog electronegative ntau dua hlau, thiab yog li oxidises hauv kev nyiam rau cov hlau, tiv thaiv cov hlau los ntawm xeb.
