Yuav ua li cas txiav txim siab tus txheej txheem galvanizing ntawm galvangized yeeb nkab?
1. Feem ntau cov ntsiab lus: saib xyuas lub qhov chaw ntawm qhov chaw (pib paub qhov txawv ntawm ib nrais muag)
Qhov sib txawv saum npoo ntawm kub - dip galvanizing thiab txias}} dip galvanizing yog qhov tseeb heev, ua qhov yooj yim tshaj plaws los siv.
2. Feem ntau txhim khu kev qha: kos kuaj (los txiav txim cov nplaum ntawm cov txheej zinc txheej)
Qhov kub - dip galvanized zinc txheej yog "molten" thiab penetrates lub substrate sab, ua rau muaj zog adhesion. Txias - dip galvanizing yog ib txheej zinc nyias nyias "electrolytically muab tso rau tom qab sib txawv tom qab khawb tom qab khawb.
Cov Cuab Yeej Ntsuas: Siv cov khoom siv tawv (xws li tus yuam sij, cov hau ntswj taub hau, lossis sab nraum qab ntawm riam hluav taws xob).
Txoj Kev Kuaj Xyuas: Siv cov quab yuam me ntsis los ua ib lossis ob qho chaw tav toj ntawm thaj chaw ntawm cov yeeb nkab (xws li sab hauv lossis xaus ntawm cov yeeb nkab phab ntsa). Saib qhov chaw khawb. Kev Txiav Txim Siab:
Kub - dip galvanized cov kav dej: tsuas yog tsim "daim tshev dawb yuav tsis yaug nrog ib tug rau tes yuav nyuaj. Yog tias qhov tsawg me me tawg tawm ntawm cov khawb, cov no feem ntau yog cov nplaim xoo feem ntau tsis muaj kev cuam tshuam tag nrho cov adhesion.
Txias - dip galvanized cov kav dej: yooj yim yuav yooj yim ua rau "zinc tev nyom yuav poob thaum kos. Thaum muaj mob hnyav, lub pib dub hlau cov khoom siv tuaj yeem pom ncaj qha, thiab tev zinc txheej yuav tshwm sim nyias thiab zaj duab xis- zoo li.
3. Muaj tseeb tshaj: Kev ntsuas Zinc Txheej Thickness (yuav tsum tau cov cuab yeej yooj yim, haum rau kev cuam tshuam tseem ceeb)
Yog tias qhov kev txiav txim siab meej meej yuav tsum muaj (xws li thaum kev lees paub ua haujlwm thiab kev xaiv cov kev xaiv tau), cov cuab yeej yooj yim tuaj yeem siv los ntsuas zinc txheej tuab. Qhov no yog qhov taw qhia tseem ceeb rau kev paub cov txheej txheem tshwj xeeb tshuab (kub}}} dip galvaning ntau dua- dip galvanizing). Kev Tuam Kev Tuam Txheej Txheem: Siv cov txheej txheem zinc zoo nkauj "(Handheld tuab daim ntaub yog pheej yig thiab haum rau kev siv nquag) txhawm rau siv ncaj qha:
Kub - dip galvanized kav: Zinc txheej tuab yog feem ntau loj dua li 60μm, nrog cov khoom lag luam engineering ncav 60-120μm.
Cold-dip galvanized pipes: The zinc coating thickness is generally<=30μm, with most being between 10-20μm, significantly thinner than hot-dip galvanized pipes.
Cov qauv sib piv yooj yim (rau kev siv tsis muaj cuab yeej):
Soj ntsuam tus "hla -}} pa xinc txheej txheem" (nyiaj} grey} Ntawm qhov txias - dip galvanized yeeb nkab hla, nrog ib qho zinc {}} grey txheej, tawm tsuas yog cov dub pob hauv paus khoom pom.
Kev sib piv ntawm kev sib piv (rau cov kav dej ntawm tib qho kev tshwj xeeb): Vim yog cov kav dej thicker, kub}}}} pa galvanized cov cheeb tsam ntawm tib lub taub thiab phab ntsa tuab. (Piv txwv li, 1 {9 {}} 'meter'} pa dej ntau dua rau cov kav dej kub dua rau cov kav dej khov.)
