Cov khoom zinc-aluminium-magnesium muaj qhov zoo li cas?

1. Kev Tiv Thaiv Kev Khawb ntawm Txheej
Qhov xeb ntawm cov ntawv coated feem ntau tshwm sim ntawm qhov khawb. Kev khawb yog qhov tsis zam, tshwj xeeb tshaj yog thaum lub sijhawm ua tiav. Yog tias daim ntawv coated muaj cov khoom tiv taus khawb, nws tuaj yeem txo qhov yuav ua rau puas tsuaj, yog li ua rau nws lub neej ntev dua. Kev sim qhia tiasCov ntawv ZAMua tau zoo dua lwm tus; lawv ua kom pom tias lawv tiv taus khawb ntau dua 1.5 npaug ntawm cov hlau galvanized-5% thiab ntau dua peb npaug ntawm cov hlau galvanized thiab zinc-aluminium. Qhov zoo dua no yog vim lawv cov txheej txheem tawv dua.

2. Kev vuam tau
Piv rau cov ntawv kub dov thiab cov ntawv txias dov,ZAMCov phaj qhia tau tias qhov vuam tsis zoo me ntsis. Txawm li cas los xij, nrog cov txheej txheem zoo, lawv tseem tuaj yeem vuam tau zoo, tswj tau lub zog thiab kev ua haujlwm. Rau cov chaw vuam, kev kho nrog Zn-Al hom txheej txheem tuaj yeem ua tiav cov txiaj ntsig zoo ib yam li cov txheej txheem qub.

3. Kev pleev xim tau
ZAM txoj kev pleev xim zoo ib yam li cov txheej galvanized-5% txhuas thiab zinc-aluminium-silicon. Nws tuaj yeem pleev xim tau, ua rau nws zoo nkauj thiab ruaj khov dua.

4. Tsis muaj qhov hloov pauv tau
Muaj cov xwm txheej tshwj xeeb uas zinc-aluminium-magnesium tsis tuaj yeem hloov pauv los ntawm lwm cov khoom:
(1) Hauv cov ntawv thov sab nraum zoov uas xav tau cov lus qhia tuab thiab cov txheej txheem saum npoo uas ruaj khov, xws li cov ntaiv txoj kev loj, uas yav dhau los vam khom rau kev galvanization ntau. Nrog rau kev tshwm sim ntawm zinc-aluminium-magnesium, kev sib txuas lus kub-dip galvanization tau ua tau. Cov khoom zoo li cov khoom siv hnub ci txhawb nqa thiab cov khoom siv choj tau txais txiaj ntsig los ntawm qhov kev nce qib no.
(2) Hauv cov cheeb tsam zoo li Tebchaws Europe, qhov chaw uas cov ntsev ntawm txoj kev tau nthuav dav, kev siv lwm cov txheej txheem rau hauv qab lub tsheb ua rau muaj kev xeb sai. Cov phaj zinc-aluminium-magnesium yog qhov tseem ceeb, tshwj xeeb tshaj yog rau cov tsev so ntug dej hiav txwv thiab cov qauv zoo sib xws.
(3) Hauv cov chaw tshwj xeeb uas xav tau kev tiv thaiv kua qaub, xws li cov tsev qaib ua liaj ua teb thiab cov tais pub mis, cov phaj zinc-aluminium-magnesium yuav tsum tau siv vim yog qhov xwm txheej corrosive ntawm cov khib nyiab qaib.
