Txhua yam kev xeem rauPrepainted Galvanized Steel Sheet
Kev sim substrate
Lub substrate thickness, hardness, thiab deg mob yuav tsum tau soj ntsuam ua ntej ntau lawm.
Xim zaj duab xis thickness kuaj
Cov xim zaj duab xis yog ib qho tseem ceeb qhia txog qhov zoo ntawmPrepainted Galvanized Steel Sheet. Yog li ntawd, peb yuav tsum tau sim seb cov xim zaj duab xis thickness ntawm txhua yob raws li tus qauv.
Cupping xeem
Lub khob khob ntsuas ntsuas qhov tsis kam ntawm cov xim ntawm cov xim, cov kua roj vanish thiab cov khoom muaj feem xyuam rau kev tawg lossis sib cais los ntawm cov hlau substrates tom qab maj mam deformation raws li cov qauv txheej txheem.
MEK wipe test
Nws yog tsuas yog siv los txiav txim siab qhov zoo ntawm txheej curing thiab kev ntsuam xyuas ntawm tsis kam mus rau organic solvents nyob rau hauv lubPrepainted Galvanized SteelCov txheej txheem ntau lawm.
T bending xeem
Lub hom phiaj ntawm kev ntsuas kev khoov ntawm cov txheej yog txhawm rau txheeb xyuas qhov yooj ntawm cov txheej txheem zaj duab xis. Nws yog ib qho ntawm cov khoom tseem ceeb los ntsuas lub cev lub cev ntawm PPGI steel ntawv los ntawm kev ntsuas qhov kev tiv thaiv kev tawg lossis tev lub peev xwm ntawm cov txheej thaum cov qauv khoov.
Kev sim hardness
Qhov kev sim hardness yog ib qho tseem ceeb rau kev ntsuas cov khoom siv, thiab nws kuj yog ib qho ntawm cov kev ntsuas ceev tshaj plaws thiab kev lag luam. Tsis tas li ntawd, nws tuaj yeem dhau los ua ib txoj hauv kev rau kev ntsuas cov cuab yeej cuab tam vim tias kev sim hardness tuaj yeem cuam tshuam qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg, cov qauv, thiab kev siv tshuab ntawm cov ntaub ntawv.
Glossy Test
Kev kuaj glossy siv lub ntsuas gloss los ntsuas seb cov khoom puas tuaj yeem ncav cuag qhov gloss raws li cov neeg siv khoom xav tau. Raws li qhov gloss ntawm qhov chaw ntawm Prepainted Galvalume Steel Sheet, nws tuaj yeem muab faib ua high-gloss, zoo tib yam, thiab matte. Ib qho cuab yeej gloss feem ntau ntsuas qhov gloss ntawmPrepainted Galvalume Steel Sheet.
Cov ntsiab lus tseem ceeb feem ntau xa mus rau glossiness ntau dua lossis sib npaug rau 75.
Ordinary gloss feem ntau txhais tau hais tias gloss yog ntau dua 40 thiab tsawg dua 75.
Lub glossiness ntawm matte xim-coated board yog tsawg dua los yog sib npaug rau 40.
