Galvanization yog dab tsi?

Galvanization yog txheej txheem ntawm kev siv cov zinc txheej tiv thaiv rau cov hlau lossis hlau txhawm rau tiv thaiv xeb thiab xeb ua ntej. Proponents ntawmgalvanized hlau, leej twg tuaj yeem siv nws los tsim lossis kho cov qauv steel, piv txwv li, tau txais txiaj ntsig los ntawm kev saib xyuas thiab kho cov nqi qis dua vim nws cov khoom tshwj xeeb.

Yog tsis muaj kev tiv thaiv, hlau yuav xeb vim huab cua puag thaum lub sij hawm. Lub degree ntawm xeb yuav nyob ntawm ib puag ncig uas cov khoom nyob rau hauv. xeb yog hlau oxide (feem ntau yog liab oxide) uas yog tsim los ntawm kev txo thiab oxidation cov tshuaj tiv thaiv ntawm hlau thiab oxygen, nyob rau hauv lub xub ntiag ntawm dej los yog huab cua noo.

Muaj cov txheej txheem tiv thaiv xws li pleev xim lossis txheej yas, tab sis cov txheej txheem no muaj qhov tsis zoo. Thaum puas lawm, ntu ntawm cov hlau yuav ua xeb thiab cov txheej tiv thaiv yuav poob, ua rau cov hom kev tiv thaiv no tsis kav ntev thiab tsis ntseeg siab (ib txwm xav tau kev saib xyuas txuas ntxiv).

Ib txoj hauv kev zoo dua los tiv thaiv cov ntaub ntawv hlau tiv thaiv corrosion yog los ntawm kub-dip galvanization. Nrogkub-dip galvanization, tag nrho cov saum npoo ntawm cov khoom yog dipped rau hauv, thiab tag nrho coated nrog, molten zinc.

Lub corrosion ntawm zinc yog qeeb heev, uas muab nws lub neej ntev thaum nws tiv thaiv lub hauv paus hlau. Vim lub alloying ntawm zinc rau hlau, cathodic tiv thaiv tshwm sim. Qhov no ua kom cov cheeb tsam me me ntawm cov hlau uas yuav raug cuam tshuam los ntawm kev puas tsuaj tsis cuam tshuam los ntawm xeb. Tsis zoo li cov organic coatings, me me puas yuav tsum tsis txhob kov. Kev tiv thaiv cathodic yuav kav ntev npaum li cov zinc txheej.

Saib xyuas tshwj xeeb yog tias koj qhov project xav tau kev sib cuag ntawm cov khoom siv galvanized thiab tooj liab lossis tooj dag. Qhov no yog qhov tseeb tshwj xeeb tshaj yog nyob rau hauv ib qho chaw ntub dej lossis qhov chaw ntub dej vim tias qhov corrosion sai ntawm zinc tuaj yeem tshwm sim. Cov dej ntws tawm ntawm cov tooj liab lossis tooj dag tuaj yeem muaj cov tooj liab txaus hauv nws kom ua rau corrosion sai. Yog tias qhov no siv rau koj qhov xwm txheej, tiv thaiv nws los ntawm kev ua kom cov dej ntws los ntawm cov khoom siv galvanized mus rau tooj dag lossis tooj liab.

Qhov zoo tshaj plaws rau kev siv Galvanized muaj xws li:

• Tus nqi qis dua stainless.
• Tsawg txij nkawm / Tus nqi qis tshaj lub sij hawm ntev.
• Lub neej expectancy ntev.
• Txheej lub neej thiab kev ua tau zoo yog txhim khu kev qha.
• Zoo heev tsis kam mus rau mechanical puas.
• Kev tiv thaiv rau cov cheeb tsam me me ntawm cov hlau raug los ntawm kev puas tsuaj.
• Tsis muaj lwm txheej txheej tuaj yeem muab kev tiv thaiv tib yam.
• Tsis muaj sij hawm poob rau hauv qhov chaw npaj, pleev xim thiab tshuaj xyuas.
