Cov yam ntxwv ntawm galvanized steel kav
Cov kav hlau dub thiab galvanized cov kav hlau yog ob qho tib si ua los ntawm cov kav hlau, tab sis cov kav dej galvanized muaj zinc txheej thaum cov kav dej dub tsis. Yog li ntawd, cov kav dej galvanized muaj ntau nqi thiab ntau cov khoom siv tau zoo.
Ua li cas galvanization tiv thaiv cov kav hlau?
Cov zinc ntawm galvanized steel cov kav dej ua tau zoo ua txheej txheej dhau los. Nws yuav xeb ua ntej cov hlau nyob hauv nws, ua kom muaj kev ncaj ncees ntawm cov yeeb nkab yuav nyob ruaj khov rau lub sijhawm ntev dua li cov kav dej tsis tu ncua. Ntxiv mus, txawm hais tias zinc txheej khawb los yog puas, nws tseem tuaj yeem tiv thaiv cov hlau hauv qab.
Ntev npaum li cas yuav galvanized steel kav kav ntev?
Lub thicker koj zinc txheej, ntev dua cov yeeb nkab kav. Qhov chaw ib puag ncig tseem ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab rau cov yeeb nkab lub neej. Yog hais tias cov kav dej tso rau hauv cov kab mob tshwj xeeb, feem ntau lawv yuav kav ntev li 50 txog 100 xyoo.
Kev siv cov kav hlau dub thiab cov kav dej galvanized steel
Cov kav hlau dub thiab cov kav dej galvanized steel yog ob hom kev siv los ua kev siv rau kev thauj cov kua thiab roj.
Cov kav hlau dub muaj feem yuav yaig dua li cov kav dej galvanized thiab vim li no, lawv nyiam siv thauj roj thaum galvanized kav rau dej nqa.
Cov txheej ntawm zinc npog cov kav dej galvanized muaj nws muaj peev xwm ntau dua ntawm kev tiv thaiv kev xeb, tab sis raws li lub sijhawm mus los ntawm nws tuaj yeem ua rau cov ntxhia ua kom tawg thiab thaiv cov yeeb nkab, uas tuaj yeem ua rau tawg. Thauj roj los ntawm kav dej galvanized yog li txaus ntshai. Hloov chaw, nws yog siv rau kev nqa dej kom xa khoom hauv tsev thiab lag luam hauv tsev lossis ua haujlwm ua scaffolding thav duab ua tsaug rau nws txoj kev tiv thaiv xeb.
Nyob rau hauv kev sib piv, dub hlau kav tsis muaj pa thiab ua tsis muaj chav. Yog li ntawd, nws yog dav siv rau kev thauj roj zoo li hluav taws roj zeb thiab ntuj tsim rau hauv tsev thiab chaw ua lag luam. Cov kav hlau dub kuj tseem tuaj yeem siv rau cov kais dej tua hluav taws vim tias nws tuaj yeem tiv thaiv hluav taws zoo dua li cov kav dej galvanized.
Sib piv cov nqi ntawm cov kav hlau dub thiab cov kav hlau galvanized
Feem ntau, cov kav hlau dub yog pheej yig dua li cov kav dej galvanized. Nws yog vim lub zinc txheej ntawm cov kav dej galvanized thiab kev tsim khoom. Galvanized fittings tseem raug nqi ntau dua qhov fittings siv ntawm cov hlau dub vim nws qhov kev thov xav tau kho.
Yuav ua li cas sib txawv dub cov kav hlau dub thiab galvanized steel kav?
Muaj ob txoj hauv kev tseem ceeb kom paub qhov txawv ntawm cov kav hlau dub thiab cov kav dej galvanized:
Ua ntej, koj tuaj yeem kuaj xyuas cov xim ntawm cov yeeb nkab. Cov yeeb nkab dub steel yog tsaus dua li cov yeeb nkab galvanized; nws yog dub dub thaum galvanized yeeb nkab yog nyiaj thiab grey.
Thiab ob, cov kav dej galvanized feem ntau yog siv rau kev thauj mus los whereas dub hlau yeeb rau xa roj.
Lwm hom kev lo tiv thaiv
Ua raws li siv cov yeeb nkab, lwm yam xim tsev lossis txheej xim ntxiv yog siv. Cov kab kev ntsuas coj los ua kom paub meej tias cov yeeb nkab tiav lawm ua tau raws li qhov ua haujlwm tshwj xeeb. Piv txwv li, cov khoom siv hluav taws xob xoo hluav taws xob yog siv los tswj hwm tus steel tuab. Lub ntsuas gauges ua hauj lwm los ntawm kev siv duab xoo hluav taws xob. Ib qho hluav taws xob yog qhia ncaj qha rau ntawm cov hlau uas paub qhov tuab hos lwm qhov ntawm cov hlau hleb rau ntawm txoj kab ntau lawm. Yog tias muaj qhov sib txawv nruab nrab ntawm ob txoj kab hluav taws xob, lub ntsuas cua yuav cia li txiav tawm ib qho resizing ntawm cov chais kom them nyiaj. Cov kav dej kuj tseem kuaj xyuas kev puas ntsoog thaum kawg ntawm kev. Ib txoj kev kuaj cov yeeb nkab yog siv cov tshuab tshwj xeeb uas ua tiav cov yeeb nkab nrog dej thiab tom qab ntawd nce lub siab kom pom tias nws tuav.
Paub qhov xwm ntawm ob qho dub hlau kav thiab galvanized steel kav, Chinh Dai hlau tau siv qib siab technology los muab cov khoom lag luam ntawm cov khoom lag luam zoo tshaj plaws rau peb cov neeg thoob ntiaj teb, suav nrog Thyssenkrupp thiab Mitsubishi.
