Dab tsi yog qhov txawv ntawm Pre-galvanized thiab kub-dip galvanized
Pre-galvanizedthiabkub-dip galvanized yog ob txoj hauv kev siv zinc txheej rau hlau. Qhov sib txawv tseem ceeb ntawm ob txoj kev no yog txoj hauv kev uas cov zinc siv tau thiab sib txuas nrog cov hlau.
Qhov txawv:
1. Cov txheej txheem ua haujlwm:
Pre-galvanization suav nrog daim ntawv thov txheej ntawm zinc rau cov hlau ua ntej nws tsim rau hauv nws cov khoom kawg. Cov hlau raug ntxuav kom huv si kom tshem tawm cov impurities lossis roj uas tuaj yeem cuam tshuam qhov adhesion ntawm zinc txheej. Tom qab ntawd daim ntawv yog dhau los ntawm ib da dej ntawm molten zinc, tsim ib txheej txheej ntawm zinc ntawm txhua sab. Cov txheej txheem no ua kom cov ntawv tiv thaiv xeb thiab corrosion.
Kub-dip galvanization, ntawm qhov tod tes, cuam tshuam rau kev tso dej ntawm cov khoom hlau hauv da dej ntawm zinc molten. Cov hlau yog thawj zaug ntxuav kom tshem tawm cov av los yog impurities uas yuav tiv thaiv kom raug adhesion ntawm cov hlau thiab zinc. Cov khoom steel yog ces dipped rau hauv da dej ntawm molten zinc, nrog rau qhov kub thiab txias ntawm zinc yog khaws cia nyob rau theem siab. Qhov kub siab ua kom ntseeg tau tias zinc coats cov hlau kom huv si, ua kom muaj kev tiv thaiv xeb thiab xeb.
2. Qhov zoo:
Pre galvanizing thiab kub-dip galvanizing muaj qhov zoo sib xws thiab sib txawv nrog cov khoom hauv qab no:
A. Zoo sib xws:
a. Kev tiv thaiv corrosion zoo heev, ua kom muaj kev tiv thaiv ntev tiv thaiv xeb thiab lwm yam corrosion.
b.Ua tib zoo ua tiav thiab cov txheej txheej tuab, muab qhov zoo nkauj zoo nkauj thiab adhesion zoo heev.
c.Ib puag ncig tus phooj ywg, xav tau lub zog tsawg dua, dej, thiab tshuaj lom neeg piv rau lwm cov txheej txheej.
d. Tus nqi-zoo thiab kav ntev, muab cov txiaj ntsig zoo rau cov nyiaj thiab txo cov nqi kho.
B. Qhov txawv:
Pre-galvanizing: Kev tiv thaiv corrosion zoo heev thiab ua tiav zoo ib yam, ib puag ncig tus phooj ywg vim lawv xav tau lub zog tsawg, dej, thiab tshuaj lom neeg piv rau lwm cov txheej txheem.
Kub-dip galvanizing: Muab cov txheej tuab ntawm kev tiv thaiv piv rau pre-galvanizing, zoo heev adhesion ntawm cov hlau thiab zinc, txhais tau tias cov txheej yuav tsis flake los yog tev tawm txawm nyob rau hauv ib puag ncig hnyav. Tsis tas li ntawd, kub-dip galvanizing yog ib qho txiaj ntsig zoo thiab siv tau ntev, muab kev tiv thaiv ntev txog 50 xyoo hauv qee kis.
Daim ntawv thov:
Pre-galvanizing: tsim cov laj kab, teeb pom kev zoo, thiab guardrails, tsheb thiab tsheb thauj mus los industries, hluav taws xob kev lag luam.
Kub-dip galvanizing: kev tsim kho, kev thauj mus los, kev ua liaj ua teb, thiab infrastructure.
