Qhov Sib txawv ntawm Galvanized Hlau Yeeb Thiab JDG Steel Yeeb Nkab

Dec 24, 2017

EMT ntawm galvanized steel yeeb nkab yog muab faib ua huab cua txias galvanized yeeb nkab thiab kub dip galvanized steel yeeb nkab. Qhov txias galvanized steel yeeb nkab tau raug txwv. Qhov txawv yog raws li nram no: JDG steel yeeb nkab.

1. Kub-dip galvanizing tube yog ua kom cov hlau molten hnov mob nrog cov hlau matrix los tsim cov hlau phom, kom lub thawv ntawv thiab txheej ob txheej ntawm cov txheej. Kub dip galvanizing yog yuav tsum tshem cov hlau oxide ua ntej, ces tshem cov hlau oxides ntawm cov kav hlau, ces nqa lawv, ces ntxuav lawv los ntawm ammonium chloride los yog zinc chloride dej tov los yog ammonium chloride thiab zinc chloride mixed dej kua tank, ces xa lawv rau hauv kub da dej da dej. Kub dip galvanizing muaj qhov zoo ntawm uniform txheej, muaj zog adhesion, ntev kev pab cuam lub neej thiab li ntawd. Txoj hauv lub cev thiab cov tshuaj tiv thaiv ntawm cov roj kub nyom galvanized hlau tub hlau matrix thiab lub tshuab da dej uas ua rau lub cev muaj zog thiab muaj zog zinc - hlau alloy txheej. Cov hlau txheej txheem ua ke nrog cov zinc ntshiab thiab hlau hlau matrix. Yog li ntawd, nws txoj kev xeb ntawm corrosion yog muaj zog.

2, cov yeeb nkab uas tsis muaj cov yeeb nkab yog galvanized, zinc plating yog tsawg heev, tsuas yog 10 - 50g / m2, nws txoj kev txhim kho corrosion ntau ntau dua li cov kub yeeb nkab. Regular galvanized yeeb txiag manufacturers, yuav kom zoo, feem ntau ntawm kev siv galvanizing (Leng Du). Tsuas yog cov lag luam me me me me thiab cov khoom siv qub siv galvanizing, ntawm chav kawm lawv cov nqi pheej yig. Qhov kev tsim kho ntawm lub tsev kawm ntawv tau tso tawm txoj haujlwm ntawm cov khoom siv thaij sab nraum qab thiab tsis pub siv cov kav dej txias rau cov kav dej thiab cov kav dej. Cov txheej txheem ntawm cov yeeb nkab uas tsis sib haum nkev ntawm cov yeeb nkab yog cov electroplating txheej, thiab cov zinc txheej thiab cov hlau hlau matrix nyias nyias nyias. Zinc txheej yog thinner thiab zinc txheej tsuas yog txuas rau hlau hlau matrix, uas yog yooj yim kom poob tawm. Vim li no, nws qhov kev xeb hluav taws xob tsis zoo. Hauv cov tsev tshiab, cov cua kub uas muaj kab uas raug qis yog raug txwv tsis pub siv dej kav.

3, JDG steel yeeb nkab yog cov khoom hloov khoom ntawm txhua hom kev hloov xov hlau, xws li PVC yeeb nkab thiab SC yeeb nkab. Nws yog ib qho kev hloov tshiab hauv kev tsim hluav taws xob nrog cov khoom tshiab thiab cov cuab yeej tshiab. Lub JDG steel yeeb nkab txais kev kho cov hlua uas muaj cov hlua khi thiab cov hlua khov hlau cov nplhaib uas yog cov nplaum txoj kab, uas ua rau muaj kev cuam tshuam ntawm cov hlau txuas hluav taws xob thiab kev tsim kho. Tib lub sij hawm, nws tseem ua rau cov teeb meem xws li tsis muaj hluav taws kub thiab tsis yooj yim ntawm PVC yeeb nkab. Vim tias tus nqi ntawm JDG steel yeeb nkab khoom ntau dua li cov yeeb nkab khoom siv, ntau qhov chaw yog siv hauv kev tsim hluav taws xob thaiv thiab hluav taws thaiv kev thaiv.
