1. Cov xim yog nplua nuj nyob rau hauv zinc hmoov, thiab electrochemical tiv thaiv ntawm zinc hmoov ua rau cov xim zaj duab xis muaj zoo heev anti-xeb kev ua tau zoo;
2. Zoo mechanical zog thiab muaj zog adhesion;
3. Muaj kev hnav zoo heev;
4. Zoo roj tsis kam, dej tsis kam thiab hnyav tsis kam;
5. Nws muaj kev tiv thaiv tsis zoo thiab ua kom sov zoo heev.Thaum lub vuam hluav taws xob raug txiav, cov zinc pos huab tsim me me, qhov kub hnyiab tau tsawg dua, thiab kev ua haujlwm vuam tsis cuam tshuam.

Txhua qhov chaw yuav tsum tau coated yuav tsum huv si, qhuav thiab tsis muaj kab mob.Ua ntej pleev xim, txhua qhov chaw yuav tsum ua raws li ISO8504: 2000 tus qauv ntsuas thiab ua tiav.
Lwm qhov chaw Cov khoom no yog siv rau lwm cov substrates, thov sab laj nrog peb cov kws tshaj lij.
Cov xim nruab nrab lossis cov coats xws li epoxy, chlorinated roj hmab, high-chlorinated polyethylene, chlorosulfonated polyethylene, acrylic, polyurethane, thiab interpenetrating network.
Txau: Tsis yog huab cua txau lossis cua txau.Kev kub siab tsis yog roj txau.
Txhuam / yob: pom zoo rau thaj chaw me me, tab sis yuav tsum tau teev tseg
1, cov khoom no yuav tsum tau muab kaw thiab khaws cia rau hauv qhov chaw txias, qhuav, qhov cua, kom deb ntawm hluav taws, tsis muaj dej, tsis muaj pov thawj, kub kub, raug tshav ntuj.
2, Raws li cov xwm txheej saum toj no, lub sijhawm cia yog 12 lub hlis txij li hnub tsim khoom, thiab tuaj yeem siv txuas ntxiv tom qab dhau qhov kev xeem, tsis muaj kev cuam tshuam rau nws cov txiaj ntsig.
