Test Method Thiab Industry Standard For Colour Coated Aluminium Coil

1, xyuas cov tsos ntawm cov xim coated aluminium yob. Qhov zoo ntawm cov xim coated aluminium coil yuav tsum tsis txhob pom tseeb embossing, to coating, deg txheej puas tshwm sim. Cov kab wavy, khawb thiab ua pob yog tsis tso cai. Cov no yooj yim pom. Qhov tseem ceeb tshaj plaws yog ua tib zoo saib xyuas cov xim ntawm aluminium coil. Yog tias koj tsis xyuam xim, nws tsis yooj yim pom, tab sis nyob rau hauv tus txheej txheem ntawm kev siv yuav cuam tshuam qhov kawg hniav nyhuv. Tam sim no, txhuas phaj ntawm lub tsev kab hlau rhuav phab ntsa kuj yuav raug kho los ntawm electrostatic hmoov txau. Cov ntaub ntawv tseem ceeb ntawm cov hmoov txau yog cov ntaub ntawv polyurethane, polyexpansive epoxy resin, epoxy resin kua nplaum thiab lwm yam ntaub ntawv raw ntxiv rau cov xim zoo, uas tuaj yeem tau txais ntau ntau yam sib txawv. Tib cov xim pleev xim hmoov, cov nyhuv zoo nkauj kuj zoo heev.
2, xyuas cov xim xim ntawm cov xim coated aluminium yob, cov no yooj yim pom thiab txheeb xyuas. Xim coated aluminium rolls tau siv dav hauv peb lub neej txhua hnub, thiab muaj ntau txoj hauv kev kom paub qhov txawv thaum peb xaiv. Xim coated aluminium coil txheej yog muab faib ua polyester coated aluminium coil (PE) thiab fluorocarbon sprayed aluminium coil (PVDF). , txawm nyob hauv tsev los yog lwm qhov chaw, vim yog cov xim nplua nuj, cov xim tsim humanized yuav tsum siv cov xim no coated aluminium yob. Coloured aluminium rolls yog nrov heev hauv kev tsim kho kev lag luam thiab yog thawj cov ntaub ntawv kho kom zoo nkauj suav nrog ntau tus tsim sab hauv. Hauv kev tsim kho vaj tse niaj hnub no, qhov xav tau ntawm cov ntaub ntawv zoo li no yog siab heev, thiab cov nyhuv zoo nkauj kuj zoo heev.
3, xyuas qhov kev ua tau zoo ntawm cov xim coated aluminium coil phaj, yuav tsum tau nqa tawm ntawm chav tsev kub. Ua ntej kev teeb tsa, xyuas lub sijhawm kom ntseeg tau tias cov khoom siv lub ru tsev tiaj tus tsis hnav, xyuas kom muaj kev siv ib txwm, thiab ua kom lub neej kev pab cuam ntawm kev siv nyob rau hauv ib txwm muaj. Lub thauj tog rau nkoj ntsia liaj qhov rooj ntawm taag xim coated aluminium yob yuav tsum tau muab ntim nrog cov khoom muaj zog noo noo-pov thawj los tiv thaiv cov av los ntawm kev nkag thiab xeb. Xim coated aluminium coil ntau lawm thiab ua haujlwm kub yuav tsum siab tshaj 7 degree. Kev tshem tawm ntawm kev tsim thiab ua cov nruas yuav tsum tau hloov kho raws li cov tuab ntawm cov xim coated aluminium coil, thiab tshem tawm cov av ntawm lub nruas thiab phaj; Tsis tas li ntawd, cov xim coated aluminium coil yuav tsum xyuas seb cov xim ntawm ob sab puas poob. Yog tias cov xim poob tawm, qhov laj thawj yuav tsum raug txheeb xyuas thiab cov kev tiv thaiv yuav tsum tau ua ua ntej kev ua haujlwm txuas ntxiv mus.
4, xyuas seb cov xim coated aluminium coil puas raug ntxuav hauv lub sijhawm. Xim coated aluminium yob yog hais txog cov menyuam txheej tshuab rau saum npoo ntawm aluminium yob coated nrog ntau yam xim ntawm cov xim. Kev tsim ntau yam xim ntawm aluminium coil, xim ntau haiv neeg, xim zoo nkauj, kev pab cuam lub neej ntev dua li cov xim hlau pobzeb, lub teeb zoo, lub zog siab, kev kho xeb thiab corrosion kuj. Muaj nuj nqi, nyob rau hauv architectural kho kom zoo nkauj, yuav ua tau ib tug zoo lwm yam xim steel pobzeb.
5, xim coated txhuas coil tshuaj xyuas txheej txheem yog yooj yim heev, tab sis cov txheej txheem ntxuav feem ntau tsis quav ntsej los ntawm cov tuam ntxhab. Cov xim coated aluminium coil yog xim daj tsaus thiab tsis zoo. Yog li vim li cas thiaj li yuav tsum muaj xim coated aluminium coil raug ntxuav hauv cov txheej txheem tsim khoom? Nyob rau hauv tag nrho cov txheej txheem ntawm txias dov, vim hais tias ntawm kev sib txhuam thiab dov ntawm kub dov sawb thiab saum npoo ntawm aluminium phaj, qhov saum npoo yuav ua rau nplua aluminium oxide hmoov shedding thiab adsorption, dov roj thiab ntxiv cov khoom ntab yuav nyob twj ywm rau saum npoo. ntawm aluminium phaj, thiab muaj kev cuam tshuam tsis zoo rau kev tsim khoom thiab kev ua tiav ntawm cov khoom tiav xws li txau thiab tsim cov xim coated aluminium phaj. Txawm li cas los xij, thaum khoov thiab ncaj, lub amorphous sawb yuav ua rau cov menyuam khoov thiab deform ntau heev. Yog li ntawd, yog hais tias lub nto ntawm cov xim coated aluminium phaj tsis tau ntxuav, cov hmoov txhuas oxide yuav poob tawm thaum nws deformed, thiab ua raws li cov menyuam nto nrog cov roj stains, ua rau muaj kev puas tsuaj rau cov menyuam nto, uas ua rau muaj kev puas tsuaj rau cov menyuam. aluminium phaj. Yog li ntawd, cov khoom siv tu cov kws tshaj lij yuav tsum tau siv. Huv huv.
