Zinc Roofing Steel Hlau Sheet

 

Zinc vov tsev steel hlau ntawv yog profiled steel phaj uas siv galvanized steel ntawv yuav dov thiab txias-tsim rau hauv ntau yam yoj duab. Nws yog dav siv los ua ru tsev, phab ntsa thiab sab hauv thiab sab nrauv phab ntsa kho kom zoo nkauj ntawm cov vaj tse, warehouses, tshwj xeeb vaj tse, loj-span steel qauv tsev thiab lwm yam.

1. Kev cuam tshuam ntawm manganese.

Manganese feem ntau yog ntxiv rau hlau ua ib qho kev ua tau zoo-txhim kho cov khoom. Yog tias cov phaj qub muaj qee yam ntawm manganese thiab cov ntsiab lus txhuas hauv zinc tov yog li ntawm 0.15 feem pua, nws muaj qhov cuam tshuam me ntsis rau kev loj hlob ntawm cov hlau-aluminium compound txheej. Txawm li cas los xij, thaum cov ntsiab lus txhuas hauv cov zinc tov yog li ntawm 0.20 feem pua, raws li cov ntsiab lus manganese nce, tiam ntawm cov hlau-aluminium compound txheej poob qis. Feem ntau, cov ntsiab lus manganese nyob rau hauv thawj lub rooj tsavxwm yog tswj ntawm li 0.25 feem pua ​​​​rau 0.40 feem pua.

2. Kev cuam tshuam ntawm tooj liab.

Cov tooj liab hauv thawj phaj tuaj yeem txhim kho qhov hnav tsis kam ntawm galvanized daim hlau. Yog li ntawd, thaum tsim cov hlau nplaum-resistant galvanized rau lub hom phiaj tshwj xeeb, cov phaj qub nrog cov ntsiab lus tooj liab ntawm 0.2 feem pua ​​​​rau 0.3 feem pua ​​feem ntau yog xaiv. Txawm li cas los xij, cov hlau uas muaj tooj liab tuaj yeem tsim cov kab nrib pleb thaum lub sij hawm kub dov, uas yog pom tseeb dua tom qab pickling, thiab tseem pom tom qab txias dov. Tom qab galvanizing, muaj streaks nyob rau saum npoo ntawm lub phaj uas zoo ib yam nrog cov kev taw qhia dov, zoo ib yam li khawb los yog strips ntawm daim hlau tuab. Yog li ntawd, cov ntsiab lus tooj liab ntawm zinc vov tsev steel hlau ntawv yuav tsum tsis txhob siab tshaj 0.15 feem pua.

3. Kev cuam tshuam ntawm phosphorus.

Phosphorus yog ib qho tsis muaj teeb meem hauv cov hlau. Phosphorus muaj qhov cuam tshuam loj heev rau galvanizing. Thaum cov ntsiab lus phosphorus yog li ntawm {{{0}}}.15 feem pua, cov hlau-zinc compound txheej yuav thicker, cov zinc txheej ntshiab yuav thinner, los yog txawm yuav tsis muaj cov zinc txheej dawb huv, thiab txheej yuav tshwm dull me ntsis, uas yuav deteriorate lub adhesion kev ua tau zoo ntawm txheej. Tsis tas li ntawd, steel strips nrog cov ntsiab lus phosphorus siab yog nkig heev, tshwj xeeb tshaj yog cov nyias nyias daim hlau nrog lub thickness ntawm 0.23mm los yog tsawg dua yog yooj yim tawg thaum khiav ntawm cov kab ntau lawm. Yog li ntawd, qhov qis dua cov ntsiab lus phosphorus ntawm galvanized thawj phaj, qhov zoo dua, thiab nws feem ntau yuav tsum muaj tsawg dua 0.025 feem pua.

4. Cov tshuaj sulfur.

Sulfur kuj yog ib qho teeb meem tsis zoo hauv cov hlau. Sulfur tsis tshua muaj txiaj ntsig rau cov txheej txheem galvanizing, tab sis leej faj cuam tshuam rau cov khoom siv ntawm cov hlau sawb. Yog li ntawd, qhov qis dua cov ntsiab lus sulfur, qhov zoo dua, thiab nws feem ntau yuav tsum muaj tsawg dua 0.03 feem pua.
