Zinc phosphate thiab nws cov kev siv

Noobrally zinc phosphate conversion txheej yog siv los muab kev tiv thaiv corrosion ntev. Yuav luag txhua qhov kev lag luam automotive siv hom kev hloov pauv txheej. Nws yog haum rau cov khoom tuaj tawm tsam huab cua hnyav. Txheej zoo yog zoo dua li hlau phosphate txheej. Nws tsim 2 - 5 g / m² txheej ntawm cov hlau nto thaum siv raws li cov xim pleev xim. Daim ntawv thov, teeb tsa thiab tswj cov txheej txheem no nyuaj dua li lwm txoj hauv kev thiab tuaj yeem siv los ntawm kev tso dej los yog tshuaj tsuag.

Organic compounds xws li npib tsib xee thiab manganese tau ntxiv rau hauv da dej kom ua rau cov txheej txheem ua tau zoo. Kuj tseem siv tau los tsim cov phosphate me me ntawm cov hlau ua ntej zinc phosphating.
Zinc phosphate cov tshuaj tiv thaiv tshwm sim hauv amorphous zoo nrog grey - dub xim.
pH optimizers yog ntxiv kom ceev cov tshuaj tiv thaiv. Qhov kub thiab txias, lub sij hawm thov, concentration, pH, tag nrho cov kua qaub thiab cov kua qaub dawb yog qhov uas yuav tsum tau tswj xyuas.

Zinc phosphates, txheej txheej ntawm 7 - 15 g / m², yog siv rau hauv kev kos duab, raj kos duab thiab kev lag luam txias. Phosphated hlau workpieces tau npaj rau theem tom ntej los ntawm kev siv cov roj nplua nyeem thiab xab npum.
