Hauv kev tsim kho vaj tse lossis kev kho dua tshiab loj, cov vaj huam sib luag xim yuav siv tau, yog li vaj huam sib luag xim yog dab tsi? Qhov laj thawj tseem ceeb vim li cas cov vaj huam sib luag xim siv dav hauv peb lub neej yog tias cov vaj huam sib luag xim muaj kev tiv thaiv corrosion zoo, yooj yim rau kev ua thiab kho dua tshiab, thiab sib dua li lwm cov ntaub ntawv. Yog li ntawd, cov vaj huam sib luag xim yuav siv rau hauv kev tsim kho. Yog li koj paub dab tsi txog kev faib tawm ntawm cov laug cam xim? Cov hauv qab no yuav qhia koj:
1. Xim coated steel phaj rau txias-dov substrate
Cov phaj xim uas tsim los ntawm cov khoom siv txias-dov muaj qhov zoo nkauj thiab du, thiab muaj kev ua haujlwm ntawm cov phaj txias-dov; tab sis txhua qhov khawb me me ntawm qhov txheej txheem saum npoo yuav ua rau cov khoom siv txias-dov rau hauv huab cua, yog li cov hlau raug nthuav tawm sai sai. Yog li ntawd, cov khoom no tsuas yog siv tau rau kev ntsuas ib ntus thiab cov khoom siv sab hauv tsev uas tsis xav tau.
2. Cov ntawv hlau uas muaj xim kub-dip galvanized
Cov khoom tau los ntawm kev pleev xim organic rau ntawm daim hlau galvanized kub-dip yog daim hlau galvanized xim-coated kub-dip. Ntxiv rau qhov kev tiv thaiv ntawm zinc, daim hlau galvanized xim-coated kub-dip kuj muaj cov txheej organic rau ntawm qhov chaw los rwb thaiv tsev thiab tiv thaiv thiab tiv thaiv xeb, thiab nws lub neej ua haujlwm ntev dua li daim hlau galvanized kub-dip. Cov ntsiab lus zinc ntawm cov khoom siv galvanized kub-dip feem ntau yog 180g / m2 (ob sab), thiab cov ntsiab lus zinc siab tshaj plaws ntawm cov khoom siv galvanized kub-dip rau sab nraud ntawm lub tsev yog 275g / m2.
3. Daim ntawv txhuas-zinc xim kub-dip
Raws li qhov yuav tsum tau ua, cov ntawv hlau txhuas-zinc kub-dip kuj tseem siv tau ua cov xim-coated substrates (55% AI-Zn thiab 5% AI-Zn). ...
4. Daim ntawv xim electro-galvanized
Cov ntawv electro-galvanized siv ua lub substrate, thiab cov khoom tau los ntawm kev pleev xim organic thiab ci yog cov ntawv electro-galvanized xim-coated. Vim tias cov txheej zinc ntawm cov ntawv electro-galvanized nyias, cov ntsiab lus zinc feem ntau yog 20/20g / m2, yog li cov khoom no tsis haum rau kev siv ua phab ntsa, ru tsev, thiab lwm yam sab nraum zoov. Tab sis vim nws zoo nkauj thiab kev ua haujlwm zoo heev, nws tuaj yeem siv rau cov khoom siv hauv tsev, suab, rooj tog hlau, kho kom zoo nkauj sab hauv, thiab lwm yam.
