Taw qhia coated steel phaj:
Coated steel daim hlau yog lub teeb yuag, zoo nkauj, muaj cov khoom zoo tiv thaiv corrosion, thiab tuaj yeem ua tiav ncaj qha. Lawv muab cov khoom siv tshiab rau kev tsim kho kev lag luam, kev lag luam shipbuilding, tsheb tsim kev lag luam, kev lag luam rooj tog, kev lag luam hluav taws xob, thiab lwm yam, thiab ua lub luag haujlwm los hloov cov hlau nrog hlau. Ntoo, siv tau zoo, txuag hluav taws xob, tiv thaiv kev ua qias tuaj thiab lwm yam zoo.
Xim-coated steel daim hlau siv galvanized steel daim hlau raws li lub hauv paus phaj, ntxiv rau kev tiv thaiv zinc, cov organic txheej ntawm zinc txheej plays lub luag hauj lwm npog thiab cais, uas tuaj yeem tiv thaiv cov hlau phaj los ntawm xeb thiab muaj kev pab cuam lub neej ntev dua li galvanized. hlau daim hlau. Raws li cov lus ceeb toom, txheej txheej Cov kev pab cuam lub neej ntawm steel phaj yog 50% ntev duagalvanized steel phaj.
Txawm li cas los xij, nyob rau hauv cov cheeb tsam sib txawv thiab cov khoom siv sib txawv, kev pab cuam lub neej ntawm cov xim-coated panels nrog tib tus nqi galvanizing, tib txheej txheej, thiab tib txheej txheej thickness yuav txawv heev. Piv txwv li, nyob rau hauv cov chaw lag luam lossis thaj chaw ntug dej hiav txwv, vim yog kev ua ntawm sulfur dioxide roj lossis ntsev hauv huab cua, tus nqi corrosion yog nrawm dua thiab kev pabcuam lub neej cuam tshuam. Nyob rau hauv lub caij los nag, yog hais tias lub txheej yog soaked los ntawm nag ntev, los yog nyob rau hauv cov cheeb tsam uas qhov kub thiab txias sib txawv ntawm nruab hnub thiab hmo ntuj yog heev loj thiab condensation yuav tshwm sim, nws yuav corrode sai thiab nws cov kev pab cuam lub neej yuav txo.
Cov vaj tsev lossis cov chaw tsim khoom ua los ntawm cov xim-coated steel daim hlau muaj lub neej ua haujlwm ntev dua thaum lawv feem ntau ntxuav los ntawm dej nag. Txwv tsis pub, lawv siv yuav raug cuam tshuam los ntawm kev ua ntawm sulfur dioxide roj, ntsev thiab hmoov av. Yog li ntawd, thaum tsim, yog txoj kab nqes ntawm lub ru tsev loj dua, nws yuav tsis tshua muaj plua plav thiab lwm yam av, thiab kev pabcuam lub neej yuav ntev dua; rau cov cheeb tsam lossis qhov chaw uas tsis nquag ntxuav los ntawm nag, lawv yuav tsum tau ntxuav tsis tu ncua nrog dej.
Xim coated steel phaj classification
Cov khoom siv xim-coated steel phaj tuaj yeem siv cov txheej txheem txias-dub, kub-dip galvanized substrates thiab electro-galvanized substrates.
Cov hom xim-coated steel phaj cais los ntawm substrate yog raws li nram no:
1. Txias dov substrate xim coated steel phaj
Cov xim xim uas ua los ntawm cov khaub thuas dov substrates muaj qhov zoo nkauj thiab zoo nkauj thiab muaj kev ua haujlwm ntawm cov ntawv txias dov; Txawm li cas los xij, ib qho me me ntawm cov txheej txheej saum npoo yuav nthuav tawm cov txheej txheem txias-dov rau saum huab cua, ua rau cov hlau raug sai. Tsim cov xeb liab. Yog li ntawd, hom khoom no tsuas yog siv rau kev ntsuas kev cais tawm ib ntus thiab cov khoom siv sab hauv tsev uas tsis tshua muaj.
2. Kub-dip galvanized xim-coated steel phaj
Cov khoom tau los ntawm txheej txheej organic ntawm kub-dip galvanized steel panels yog kub-dip galvanized xim-coated panels. Ntxiv rau qhov kev tiv thaiv ntawm zinc, cov ntawv kub-dip galvanized xim-coated ntawv kuj tseem muaj cov txheej txheem organic rau ntawm qhov chaw uas tiv thaiv thiab tiv thaiv xeb, thiab muaj lub neej ua haujlwm ntev dua li cov ntawv kub-dip galvanized. Cov ntsiab lus zinc ntawm kub-dip galvanized substrates feem ntau yog 180g / m2 (ob tog), thiab zinc cov ntsiab lus ntawm kub-dip galvanized substrates rau cov tsev sab nrauv yog txog 275g / m2.
3. Kub-dip aluminium-zinc xim-coated ntawv
Raws li kev thov, kub-dip aluminium-zinc steel los xij tuaj yeem siv los ua cov xim coated substrates (55% Al-Zn thiab 5% AI-Zn).
4. Electro-galvanized xim-coated ntawv
Cov khoom tau txais los ntawm kev siv ib daim ntawv electro-galvanized raws li lub substrate, txheej nws nrog organic xim thiab ci nws yog ib tug electro-galvanized xim-coated vaj huam sib luag. Txij li cov zinc txheej ntawm cov ntawv electro-galvanized yog nyias thiab cov ntsiab lus zinc feem ntau yog 20/20g / m2, cov khoom no tsis haum rau kev siv. Ua phab ntsa, ru tsev, thiab lwm yam sab nraum zoov.
Txawm li cas los xij, vim nws cov tsos zoo nkauj thiab kev ua haujlwm zoo heev, nws tuaj yeem siv rau hauv cov khoom siv hauv tsev, suab, steel rooj tog, kho kom zoo nkauj sab hauv, thiab lwm yam.
5. Xim
Txheej yog cov khoom siv organic hauv cov kua lossis hmoov hmoov. Thaum ua ntawv thov rau lub substrate, nws dries thiab solidifies tsim ib tug nyias zaj duab xis uas sib npaug zos npog thiab adheres zoo.
Nws cov khoom tseem ceeb yog kev tiv thaiv (xws li dej tsis kam, dej tsis kam, huab cua tsis kam, tshuaj tiv thaiv, thiab lwm yam) thiab cov hniav zoo nkauj (nrog ntau yam xim thiab gloss).
