Corrugated vov tsev thiab siding yog nrov nrog cov tswv tsev thiab cov lag luam sib npaug, ua tsaug rau cov txiaj ntsig zoo xws li kev ua neej ntev, kev txhim kho yooj yim, thiab kev tswj qis. Feem ntau ntawm cov khoom siv corrugated yog tsim los ntawm cov hlau tsis xeb hlau. Galvanization yog txheej txheem ntawm kev thov ib txheej bacteria nyias ntawm zinc rau saum npoo ntawm hlau kom tiv thaiv nws ntawm xeb (oxidization) thiab xeb.
Zinc huab cua nyob hauv tus nqi qeeb heev, yog li cov txheej feem ntau muaj lub neej ntev. Zinc muaj ntau dua electro-negativity dua li hlau thiab chaw pib muab kev tiv thaiv cathodic (lossis fij tseg) tiv thaiv cov hlau.
Qhov no ua rau cov zinc corroding nyob rau hauv qhov kev xaiv ntawm cov hlau yog tias txheej txheej chipped lossis puas rau ua kom lub hauv paus hlau.
Dhau li ntawm kev ua cov galvanic tiv thaiv, Lwm cov dej num ntawm zinc txheej yog raws li:
Txhawm rau kom ruaj khov cov hlau nrog nws lub zog thawj zaug.
Txhawm rau muab cov nplaim xim zoo nkauj dua.
Yuav kom nce lub neej ntawm ib yam haum organic xov system thov tshaj nws.
Txhawm rau tiv thaiv cov hlau los ntawm kev tiv thaiv corrosive nyob rau hauv cov huab cua feem ntau, ua raws li kev tiv thaiv txuas ntxiv thiab kav ntev ntawm cov hlau thiab cov huab cua.
