Vim li cas galvanized steel kav yog nrov heev hauv tsev cog khoom?
Raws li paub zoo, galvanized steel kav yog coated nrog zinc tiv thaiv txheej, uas muaj zog tiv thaiv xeb tiv thaiv thiab siab zog dua lwm cov hlau thiab hlau kav. Cov txheej txheem ntawm galvanizing yuav tshem tawm cov hlau oxide los ntawm cov kav hlau los ntawm kev ntxuav cov kua qaub, thiab tom qab ntawd muab tso rau hauv cov kua dej ntawm zinc chloride lossis ammonium chloride thiab zinc chloride, thiab tom qab ntawd muab tso rau hauv lub molten zinc da dej lossis zinc nplua nuj electrolyte. . Zinc reacts nrog oxygen los tsim zinc oxide txheej, uas ntxiv reacts nrog carbon dioxide los tsim zinc carbonate los tiv thaiv corrosive tshuaj los ntawm ncav cuag hlau los yog hlau hauv qab no.
Galvanized kav yog dav siv sab nraum zoov thiab sab hauv tsev vim lawv xeb kuj. Hauv kev ua liaj ua teb, cov kav hlau galvanized tau siv dav hauv tsev cog khoom, cog qoob loo, thiab kev ua haujlwm horticultural. Lub tsev cog khoom thav duab yog ua los ntawm galvanized nyias-walled steel kav, sib sau ua ke nrog arch rods, longitudinal rods, membrane grooves, membrane springs, taub hau, qhov rooj, thiab sab cua tshuab.
Tus nqi qis dua
Lub tsev xog paj thav duab galvanized yeeb nkab yog ua los ntawm cov pa roj carbon zoo tib yam nrog kub-dip zinc txheej, uas yog tus nqi qis dua stainless hlau. Nyob rau lub sijhawm ntev, nws yooj yim rau kev siv, nruab, thiab thauj, thiab tsis tas yuav muaj kev txhawb nqa cov kav dej hauv tsev, uas yog qhov tsim nyog rau kev ua haujlwm ntawm cov tshuab.
Lub neej ua haujlwm ntev
Kev pabcuam lub neej ntawm galvanized steel kav tuaj yeem ncav cuag 15 xyoo. Nws muaj zog daus tiv taus, tsis tshua muaj thermal conductivity, thiab zoo thermal rwb thaiv tsev, thiab yuav tsis deform txawm nyob rau hauv txias los yog kub ib puag ncig ntawm rho tawm 100 degree C mus rau 60 degree C. Galvanized steel kav muaj nqi txij nkawm qis, tuaj yeem soj ntsuam nrog kev kawm ob lub qhov muag, thiab yooj yim rau assemble.
Cov tsos zoo
Cov zinc txheej ntxiv hauv cov kav dej galvanized ua kom lub ntsej muag tuab thiab zoo ib yam los ntawm txhua sab. Galvanized coatings yog txawv los ntawm cov organic coatings nyob rau hauv qhov chaw me me puas tsis tas yuav hloov kho, thiab cov tsos grey tuaj yeem nyob ntev.
Piv nrog cov qauv tsim los ntawm cov ntaub ntawv xws li xyoob, ntoo, hlau vuam, thiab cov av sib xyaw ua ke yav dhau los, cov kav dej galvanized steel muaj cov khoom tseem ceeb xws li lub zog siab, zoo corrosion kuj, tsawg noj, yooj yim installation, thiab tus nqi qis. Lawv tau siv dav hauv kev lag luam ua liaj ua teb. Thov hu rau peb thaum xav tau rau tag nrho cov kav dej galvanized hauv tsev cog khoom.
Kev mus ntsib los ntawm cov neeg siv khoom Armenian
Txij li thaum nws tsim, GNEE Group tau ua raws li txoj cai tswj hwm ntawm "zoo ua ntej, tus neeg siv thawj zaug, thiab lub koob npe nrov ua ntej", ib txwm siv zog ua kom tau raws li qhov xav tau ntawm cov neeg siv khoom. Peb lub tuam txhab txaus siab koom tes nrog kev koom tes nrog cov tuam txhab los ntawm thoob plaws lub ntiaj teb kom ua tiav qhov xwm txheej yeej-yeej. Yog tias koj muaj lus nug lossis xav tau, peb ib txwm muaj los teb lawv.
