Qhov tseem ceeb sib txawv ntawm aluminized zinc coil thiab galvanized coil nyob rau hauv plaub yam: txheej txheej, corrosion kuj, ua cov yam ntxwv, thiab cov xwm txheej.
Nyob rau hauv cov nqe lus ntawm txheej muaj pes tsawg leeg, galvanized coil lub txheej yog tsuas yog zinc los yog zinc alloy, nrog ib tug yooj yim muaj pes tsawg leeg; aluminized zinc coil muaj ib qho txhuas, zinc, thiab silicon alloy txheej, nrog rau kev sib xyaw ua ke ntau dua.
Regarding corrosion resistance, aluminized zinc coil, due to the aluminum content forming a dense oxide film, has 2-5 times the corrosion resistance of galvanized coil, and superior weather resistance and salt spray resistance, making it suitable for long-term outdoor use; galvanized coil tsuas yog nyob ntawm zinc raws li kev txi anode rau kev tiv thaiv, ua rau nws yooj yim rau corrosion nyob rau hauv ib puag ncig hnyav.
Nyob rau hauv cov nqe lus ntawm kev ua cov yam ntxwv, aluminized zinc coil muaj zog txheej adhesion thiab zoo weldability thiab paintability, tab sis yuav tsum tau saib xyuas kom tsis txhob txheej cracking thaum stretching thiab dabtsi yog khoov; galvanized kauj yog hloov tau yooj yim hauv kev ua thiab muaj zog tensile zoo me ntsis.
Nyob rau hauv cov nqe lus ntawm cov xwm txheej, aluminized zinc coil yog tsim rau kev tsim kho sab nraum zoov thiab ib puag ncig corrosive heev; galvanized coil yog tsim rau cov khoom siv sab hauv tsev thiab cov xwm txheej uas yuav tsum tau muaj kev tiv thaiv corrosion.
