Title: Dab tsi yog qhov ceev ntawm galvalume steel ntawv?
Thaum tshav kub kub tsis kam: Cov khoom kub-dip galvanized feem ntau yog siv ntawm qhov kub tsis tshaj 230 degrees. Lawv yuav hloov xim ntawm 250 degrees, thaum cov nplooj ntawv galvanized tuaj yeem siv rau hauv ib puag ncig ntawm 315 degrees yam tsis muaj xim rau lub sijhawm ntev. Tom qab raug 300 degrees rau 120 teev, cov xim hloov ntawm lub tshav kub-resistant passivation kho galvanized steel phaj yog qis dua li ntawm txhuas phaj thiab aluminized phaj.
Qhov ntom ntawm aluminium alloy feem ntau yog nyob ib ncig ntawm 7g / cm3, thiab nws qhov hnyav tuaj yeem suav nrog cov qauv ntom ntom: qhov hnyav × ntim. Yuav kom suav tau, qhov hnyav ntawm galvalume phaj tuaj yeem xam los ntawm cov qauv hauv qab no: qhov hnyav ntawm txhuas txheej + qhov hnyav ntawm zinc phaj. Ntawm lawv, qhov hnyav ntawm aluminium plated txheej, qhov ntom ntawm aluminium alloy × qhov ntim ntawm aluminium plated txheej, thiab qhov hnyav ntawm zinc phaj, qhov ntom ntawm zinc phaj × qhov ntim ntawm zinc phaj. , nws yuav tsum raug sau tseg tias qhov hnyav ntawm cov ntawv galvanized kuj tseem cuam tshuam los ntawm lwm yam, xws li kub, av noo, thiab lwm yam. Yog li ntawd, thaum siv cov ntawv galvanized, cov lus qhia tsim nyog yuav tsum raug xaiv kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm lawv siv. Zuag qhia tag nrho, qhov hnyav ntawm cov ntawv galvalume yog qhov teeb meem nyuaj nrog ntau yam los xav txog. Kab lus no qhia txog yuav ua li cas xam qhov hnyav ntawm cov ntawv galvanized thiab vam tias yuav pab tau rau txhua tus. Yog tias koj tseem muaj lus nug, thov hu rau cov neeg ua haujlwm kom paub meej cov ntaub ntawv raug dua.

Qhov ceev ntawm aluminized steel phaj yog 85g / cm3. Aluminized steel phaj yog aluminium-silicon alloy coated steel phaj, uas cov ntsiab lus txhuas yog 90% thiab silicon yog 10%. Lub tshav kub tsis kam ntawm aluminized steel los xij yog qhov zoo tshaj plaws ntawm cov ntawv hlau galvanized thiabtxias dov steel ntawvs. Vim yog kev sib xyaw tshwj xeeb ntawm cov hlau phaj hauv cov khoom siv thiab cov txheej txheem txheej, ib qho hlau-aluminium alloy yog tsim, uas muab cov phaj aluminized zoo heev kub tsis kam.
Qhov ceev ntawm galvalume steel ntawv yog 86; vim tias cov txheej txheej yog nyias nyias, qhov tshwj xeeb lub ntiajteb txawj nqus tuaj yeem tsis quav ntsej hauv kev suav. Galvalume-coated steel phaj yog alloy-coated steel phaj dav siv nyob rau hauv ntau qhov chaw xws li cov khoom siv hauv tsev, khoom siv hauv tsev, tsheb, ib puag ncig, tshuab, thiab nkoj.
Qhov ceev ntawm galvalume steel ntawv yog 86g/cm^3; vim tias cov txheej txheej yog nyias nyias, qhov tshwj xeeb lub ntiajteb txawj nqus tuaj yeem tsis quav ntsej hauv kev suav. Galvalume steel phaj yog them nrog aluminium-zinc alloy ntawm lub phaj steel. Nws yog tsim los ntawm 55% txhuas, 44% zinc thiab 6% silicon solidified ntawm qhov kub ntawm 600 degree. Nws tag nrho cov qauv yog tsim los ntawm txhuas, hlau, silicon thiab zinc, ua ib tug ntom quaternary siv lead ua. Ib tug alloy-coated steel phaj.
Qhov ntom ntawm galvanized steel Zinc yog ib qho khoom siv hlau uas muaj kev tiv thaiv corrosion zoo thiab yog li siv dav hauv ntau yam. Ntawm lawv, kev sib xyaw ntawm zinc thiab hlau ua cov khoom hu ua galvanized steel.
