Cov zinc tso zis los yog zinc pots siv rau qhov kub-dip galvanizing feem ntau siv cov hlau uas tsis tshua muaj cov pa uas tsis tshua muaj neeg qis. Qhov no yog kom tsis txhob muaj qhov txhuam thiab kub ntxhov uas tshwm sim thaum siv. Yog hais tias cov zinc lauj kaub cov khoom siv tsis zoo, nws yuav zoo heev kom txo tau cov kev pab cuam lub neej ntawm zinc lauj kaub. Cov phom sij phem los yog cov nplua nuj carbon tsis tsim nyog rau kev siv ua zinc pots, thiab ntau cov ntaub ntawv tshiab tau tawm los hloov cov hlau, xws li cov khoom siv zom ua ntxhua thiab cov thawv ntoo. Raws li kev txhim kho, nws tseem tuaj yeem siv lub zinc luj tiv thaiv txheej rau sab hauv phab ntsa ntawm cov zinc cov zis, xws li muaj kev lag luam ceramic txheej. Qhov no muaj cov txheej txheem ceramic yuav tsum ua raws li cov hauv qab no:
(1) Tus qauv yog nruj thiab tiav, tsis muaj qhov;
(2) Muaj zog tiv thaiv nrog lwm cov hlau;
(3) kev kub ntxhov, hnav ua haujlwm, kev xeb tuaj;
(4) Uniformly faib rau tag nrho kev tiv thaiv nto, thiab lub peev xwm ntawm lub substrate zoo yog zoo;
(5) Nws tuaj yeem kov yeej qhov teeb meem ntawm thermal expansion deformation los ntawm kev sib txawv coefficients ntawm ob hom ntaub ntawv.
