Dab tsi yog Txoj Kev Kho Nto Rau Channel Steel?

Txoj kev kho saum npoo rau channel steel tuaj yeem muab faib ua plaub pawg. Txhua txoj kev muaj nws cov yam ntxwv tshwj xeeb ua thiab cov xwm txheej siv tau.

Qhov no yog cov txheej txheem tseem ceeb rau kev ncua kev pab cuam lub neej ntawm channel steel, thiab nws feem ntau suav nrog:

• 1. Sandblasting xeb tshem tawm: Siv high - xuab zeb txau kom tshem tawm cov oxide txheej thiab xeb ntawm qhov chaw, ua kom lub ntsej muag du.

• 2. Acid Washing Rust Tshem Tawm:Siv cov tshuaj acidic kom yaj cov oxides saum npoo thiab xeb.

• 3. Kub-dip Galvanizing:Immersing cov channel steel hauv molten zinc kua los ua xeb- tiv thaiv txheej.

Qhov no yog txoj hauv kev tseem ceeb rau kev txhim kho corrosion, thiab nws tau muab faib ua:

• 1. Kub Galvanization:Cov hlau tuav yog immersed nyob rau hauv siab - kub zinc tov thiab galvanized los ntawm ib tug thermal cov tshuaj tiv thaiv. Cov nyhuv tiv thaiv yog qhov zoo thiab nws tsim nyog rau qhov chaw hnyav.

• 2. Electro-galvanization (Cold Plating):Zinc ions tau tso rau ntawm qhov chaw los ntawm cov hluav taws xob tam sim no, tsim ib txheej zinc txheej. Kev ua haujlwm yog yooj yim thiab cov tsos zoo yog qhov zoo.

Cov txheej txheem no tsuas yog siv los txhim kho cov nyhuv zoo nkauj thiab zoo nkauj. Cov txheej txheem tsim khoom muaj plaub theem: sanding, primer, intermediate coat, thiab topcoat. Ntau hom xim cov ntaub ntawv xws li epoxy xim thiab polyurethane xim tuaj yeem xaiv kom tau raws li qhov xav tau ntawm ib puag ncig sib txawv.

• 1. Kev kho phosphating:Tsim cov phosphate tiv thaiv zaj duab xis, txhim kho corrosion kuj thiab txhim kho cov adhesion ntawm txheej.

• 2. Kev kho kev sib tsoo:Xws li kev sib tsoo tshuab thiab tshuaj lom neeg sib tsoo, txhim kho qhov tseeb thiab smoothness.

• 3. Anodizing:Feem ntau yog siv rau cov ntaub ntawv txhuas, tsim cov oxide zaj duab xis los ntawm electrolysis.

• 4. Hlau Drawing Kev Kho Mob:Ua tiav ib txoj kab zoo nkauj los ntawm kev sib tsoo, ua kom pom cov xim hlau zoo nkauj.

• Ib puag ncig nrog cov av noo siab thiab muaj zog corrosiveness (xws li cov chaw nyob hauv hiav txwv): Xaiv rau kub -dip galvanizing.

• Rau qhov chaw nyob sab hauv tsev nrog cov kev xav tau siab rau cov tsos: Koj tuaj yeem xaiv cov xim pleev xim lossis cov txheej txheem txias plating.

• Thaum nws yog ib qho tsim nyog los txhim kho qhov adhesion ntawm txheej: phosphating kev kho mob tuaj yeem ua ntej.

Thaum ua qhov kev xaiv tiag tiag, ntau yam xws li kev siv ib puag ncig, kev siv nyiaj txiag thiab kev ua haujlwm yuav tsum tau muab coj los txiav txim siab.
