Zinc paj yog ib qho tseem ceeb feature ntawm cov tsos ntawmkub-dip galvanized ntawvs.
Qhov saum npoo ntawm kub-dip txheej ntawm cov hlau phaj yuav tshwm sim cov qauv siv lead ua ntawm cov txheej hlau thaum lub sij hawm solidification. Cov qauv siv lead ua no tshwj xeeb tshaj yog pom tseeb rau cov phaj galvanized, uas qhia txog qhov zoo nkauj ntawm cov pob zeb zinc. Vim tias nws zoo ib yam li cov paj ntoo, cov qauv siv lead ua no feem ntau hu ua "Zinc paj".
paj zinc
Yuav ua li cas zinc paj tsim?
Cov txheej txheem ntawm kev tsim cov paj zinc tsis nyuaj. Thaum cov hlau sawb hla dhau lub lauj kaub zinc, qhov saum npoo yog coated nrog kua zinc. Raws li zinc txheej solidifies lawm, zinc nplej nucleate thiab loj hlob, thiab zinc flakes zoo li snowflakes tshwm.
Txawm li cas los xij, yog tias muaj pes tsawg leeg ntawm cov kua zinc yog cov purity siab, nws yuav nyuaj los yog tsis yooj yim sua kom tsim cov paj zinc, vim tias cov kua zinc tsis muaj qhov tsim nyog crystallization nuclei.
Kev faib tawm ntawmgalvanized ntawv
Raws li qhov sib txawv ntawm cov ntawv hlau galvanized, lawv feem ntau muab faib ua:
Paj galvanizing thiab flowerless galvanizing
Dab tsi yog paj galvanizing?
Paj galvanizing tseem hu ua ib txwm zinc paj lossis zinc paj loj. Nws yog hais txog zinc paj nrog ib txoj kab uas hla ntau dua 3 hli uas muaj peev xwm paub qhov txawv ntawm qhov muag liab qab. Lub thoob ntiaj teb pom zoo qhov loj ntawm zinc paj loj yog 8 ~ 12 hli. Cov txheej txheem yog vim tias tom qab lub phaj hlau tau rub tawm ntawm cov kua zinc uas muaj cov hlau lead, antimony thiab lwm yam khoom, zinc nplej tau loj hlob dawb, tsim ib lub phaj hlau galvanized nrog pom tseeb zinc paj.
Dab tsi yog flowerless galvanizing?
Flowerless galvanizing yog hais txog cov paj zinc uas tsis tuaj yeem pom ntawm qhov muag liab qab, los yog hu ua "zero zinc paj". Flowerless galvanizing feem ntau ua tiav los ntawm kev tswj cov tshuaj muaj pes tsawg leeg ntawm cov tshuaj zinc. Thaum kub-dip galvanizing, tsuas yog ib qho nyiaj ntawm txhuas ntxiv rau zinc tov, tsis ntxiv cov hmoov txhuas, antimony, los yog tin, los tsim cov khoom seamless galvanized.
