t muaj 55% hauv qhov hnyav aluminium, 43.4% hauv qhov hnyav zinc thiab 1.6% hauv qhov nyhav silicone. Nws yog dav siv nyob rau hauv ntau yam kev lag luam xws li kev tsim kho vaj tsev ntawm sab nraud, hluav taws xob cov cuab yeej hluav taws xob tsheb, thiab lub hlwb xa hluav taws xob, vim nws cov khoom lag luam zoo thiab kev ua tau zoo.
Zoo ib yam li galvanized steel, Galvalume yog tsim los ntawm cov txheej txheem kub-dip. Hloov chaw 100% zinc, lub dip yog 55% txhuas, 43.5% zinc thiab 1.5% silicon. Galvalume Steel Chev muaj kev ua tau zoo heev, muaj cov khoom zoo heev ntawm kev tiv thaiv corrosion, tsim thiab txheej.
Galvanized ntawv lossis coil txhais tau yog cov ntawv carbon steel coated nrog zinc ntawm ob sab.
Ib txheej zinc yog ib qho ntawm cov kev ua tau zoo thiab kev siv nyiaj tiv thaiv kev tiv thaiv cov hlau tsis huv los ntawm qhov chaw muaj corroding.
Cov zinc tsis tsuas yog ua lub qhov thaiv nruab nrab ntawm cov hlau thiab ib puag ncig, nws yuav txi nws tus kheej los tiv thaiv lub qhov cub steel daim hlau.
Kev faus, lossis kev tiv thaiv galvanic tshwm sim thaum ob qho hlau tsis sib luag yog hauv kev sib cuag thiab txuas nrog dej thiab oxygen.
Zinc corrodes nyiam dua rau cov hlau hauv cov hlau.
Qhov kev tiv thaiv no tiv thaiv xeb ntawm cov hlau ntawm cov chaw uas tsis muaj zinc.
Yog li, kev sib kis los ntawm kev xeb los ntawm kev txiav rau cov kav, laum qhov, thiab lwm yam.
