Xov xwm

Galvanized steel yeeb nkab, tseem hu ua galvanized steel yeeb nkab, muab faib ua ob hom: kub-dip galvanizing thiab electrogalvanizing.Cov txheej kub-dip galvanized yog tuab, zoo ib yam, muaj zog adhesion thiab kev pab lub neej ntev.Galvanizing tus nqi qis, thiab qhov saum npoo tsis du heev.Galvanized yeeb nkab yog ib hom steel yeeb nkab dipped nrog zinc tiv thaiv txheej los tiv thaiv corrosion thiab xeb.Cov kav dej Galvanized tau teeb tsa hauv tsev ua ntej xyoo 1970 thiab 1980s.Thaum lub sijhawm tsim khoom, cov kav dej galvanized tau hloov pauv rau cov kav dej.Hauv kev muaj tiag, nws paub zoo tias cov kav dej tau raug rau ntau xyoo lawm, ua rau corrosion thiab xeb ntawm cov kav dej galvanized.Cov yeeb nkab galvanized zoo li cas?
Cov tsos ntawm galvanized yeeb nkab zoo ib yam li npib tsib xee.Txawm li cas los xij, raws li lub sijhawm dhau mus, cov yeeb nkab galvanized yuav tsaus dua thiab ci dua, nyob ntawm nws qhov chaw.Ntau lub tsev nrog cov kav dej ntawm lawv yuav nyuaj rau kev paub qhov txawv thaum xub thawj siab ib muag.
Yuav ua li cas koj paub yog hais tias nws yog galvanized yeeb nkab?
Yog tias cov kav dej tsis tuaj yeem txiav txim siab, koj tuaj yeem txiav txim sai sai seb nws puas yog galvanized.Txhua yam koj xav tau yog lub tiaj tus ntsia hlau thiab hlau nplaum.Nrhiav cov kav dej thiab txhuam sab nraud ntawm cov yeeb nkab nrog lub hau ntswj.
Cov txiaj ntsig sib piv:
tooj liab
Qhov kos zoo li lub npib tooj liab.Cov hlau nplaum yuav tsis lo rau nws.
Yas
Kos tuaj yeem yog mis nyuj dawb lossis dub.Cov hlau nplaum yuav tsis lo rau nws.
Galvanized hlau
Cov khawb yuav yog silver grey.Cov hlau nplaum muaj zog yuav ntes nws.
Puas yog cov yeeb nkab galvanized muaj cov khoom tsim kev puas tsuaj rau cov neeg nyob hauv?
Nyob rau hauv thaum ntxov hnub ntawm kev ywj pheej, galvanized kav ntsia tau rau hauv cov kav dej yog immersed nyob rau hauv molten natural zinc.Cov zinc tshwm sim ib txwm muaj tsis huv, thiab cov kav dej no tau muab tso rau hauv zinc uas muaj cov hlau lead thiab lwm yam impurities.Cov zinc txheej txuas ntxiv lub neej kev pab cuam ntawm cov yeeb nkab steel, tab sis ntxiv me me ntawm cov hlau lead thiab lwm yam khoom uas yuav ua rau cov neeg nyob.
