Coil Galvalume lossis lus txias Galvalume Steel Sheet Hauv Chev yog cov ntawv carbon steel coated nrog aluminium zinc alloy los ntawm cov txheej txheem kub kub tas li.Qhov nominal txheej muaj pes tsawg leeg yog 55% txhuas thiab 45% zinc.
Ib qho me me tab sis tseem ceeb ntawm silicone yog ntxiv rau txheej txheej.
Nws tsis yog ntxiv los txhim kho corrosion, tab sis muab cov txheej txheem zoo adhesion rau steel substrate thaum cov khoom dov, ncab lossis khoov thaum tsim khoom.
Galvanized steel ntawv ua ke nrog kev tiv thaiv corrosion zoo heev ntawm txhuas nrog kev tiv thaiv ntawm galvanized steel.
Qhov tshwm sim yog cov txheej txheem ruaj khov, ib qho uas muab kev tiv thaiv lub xeev-ntawm-tus-kos duab raws cov npoo sheared thiab, yog li ntawd, ib qho uas muab kev tiv thaiv zoo rau cov nplooj ntawv steel.
Txawm hais tias muaj qee qhov kev zam, rau feem ntau cov ntawv thov nyob rau hauv ntau qhov chaw, thaum lub sij hawm ntev atmospheric corrosion kuj yuav tsum tau, galvanized steel yog cov khoom ntawm kev xaiv.
Nws yog qhov ruaj khov dua li qhov sib npaug ntawm cov txheej txheej galvanized thiab muaj kev tiv thaiv lub xeev-ntawm-tus-kos duab tsis pom nyob rau hauv aluminium-coated panels.
Qhov kev tiv thaiv qib siab no txhais tau tias tsis muaj xeb, khawb thiab lwm yam tsis zoo hauv qhov ua tiav ntawm cov npoo shaved.Tsis tas li ntawd, vim tias cov txheej txheej no muaj kev tiv thaiv corrosion heev, nws tuav lub ntsej muag ci ntsa iab thaum raug rau feem ntau cov cua.
Cov khoom no ua rau Galvalume steel ntawv cov khoom xaiv rau vov tsev.Qhov zoo heev corrosion kuj ntawm galvanized steel los xij yog ua tiav los ntawm lub xub ntiag ntawm zinc- thiab txhuas-nplua nuj microscopic domains nyob rau hauv lub txheej.
Aluminium-nplua nuj cheeb tsam uas corrode qeeb heev muab lub sij hawm ntev, thaum zinc-nplua nuj cheeb tsam uas corrode preferentially muab kev tiv thaiv galvanic.
