Yooj yim
Thaum lub sij hawm reprocessing ntawmPPGI Chev Sheet, thaum lub npoo yog khoov thiab xuas nrig ntaus, txheej zaj duab xis tsis yog tsuas yog nyem thiab khoov tab sis kuj ncab. Yog li ntawd, txhawm rau tiv thaiv cov yeeb yaj kiab los ntawm kev tawg lossis tawg nyob rau hauv ib qho tshwj xeeb ntawm kev ua thiab deformation, cov txheej txheem kho yuav tsum muaj qhov zoo elasticity thiab toughness.
Zaj duab xis Adhesion
Txij li thaumPPGI Chev Sheetyuav tsum tau ua tiav thaum lub sij hawm siv, lub nto txheej zaj duab xis kuj raug extrusion, shearing, stretching, thiab lwm yam quab yuam los tsim deformation, yog li lub txheej zaj duab xis yuav tsum tau muaj zog adhesion rau steel phaj, tshwj xeeb tshaj yog thaum lub hauv paus thiab txheej zaj duab xis yog deformed mus rau txawv degrees nyob rau tib lub sij hawm, lawv tseem yuav tsum muaj ib tug tseem ceeb adhesion los xyuas kom meej tias yuav tsis muaj blistering thiab ntog tawm thaum lub sij hawm ua. Yuav tsum muaj cov txheej txheem sib txuam thiab kev siv cov txheej txheem nruj kom tau txais adhesion zoo. Degreasing, phosphating, passivation, txheej ntau yam thiab sib txuam, qhov kub thiab txias, thiab lub sij hawm tag nrho cuam tshuam rau adhesion.
Corrosion thiab aging kuj
Thaum lub sij hawm siv, lub substrate tsis nyob rau hauv ncaj qha kev sib cuag nrog ib puag ncig vim kev tiv thaiv ntawm lub txheej zaj duab xis. Txawm li cas los xij, txij li dej, oxygen, haus luam yeeb, thiab lwm yam corrosive gases nyob rau hauv ib puag ncig, xws li sulfur dioxide, tseem tuaj yeem nkag mus rau saum npoo los ua ib zaj duab xis thiab maj mam ua rau corrosion ntawm lub substrate, tsub zuj zuj ntawm cov khoom siv corrosion yuav ua rau cov khoom tawg. txheej zaj duab xis ua npuas ncauj los yog txawm poob. Ntawm qhov tod tes, zaj duab xis txheej yuav muaj hnub nyoog nyob rau hauv qhov kev txiav txim ntawm tshav ntuj, tshav kub, los nag, thiab huab cua kub thiab poob nws cov nyhuv tiv thaiv ntawm lub substrate. Txawm hais tias qhov no tsis tuaj yeem zam tau, cov txheej txheem muaj kev tiv thaiv corrosion zoo thiab muaj peev xwm tiv thaiv kev laus, uas yog qhov tseem ceeb ntawm cov txheej txheem.
Kev ua qias tuaj
Cov rooj tog zaum, cov khoom siv hluav taws xob, thiab lwm yam khoom ua los ntawmPPGI Chev SheetTej zaum yuav muaj feem xyuam rau cov khoom xws li kua ntses, kua roj, jam, number case, ballpoint cwj mem roj, naj hoom, khau polish, thiab lwm yam, yog li tawm ntawm cov xim sib txawv ntawm qhov chaw. Anti-paste thiab graffiti teeb meem yuav tsum tau txiav txim siab thaum siv los ua cov khoom siv hauv tsev. Txhawm rau ua kom lub ntsej muag ntawm cov xim-coated phaj, xws li cov tais diav lossis cov tsev, huv si, nws yuav tsum tau ua kom cov khoom no tsis txhob paug rau saum npoo ntawm cov xim-coated rigid phaj. Ua ib kauj ruam rov qab, txawm tias tom qab kis tau los ntawm cov tshuaj no, nws yog ib qho yooj yim los ntxuav yam tsis muaj kab. Tau txais qhov zoo stain kuj feem ntau yog nyob ntawm kev xaiv thiab kev kho kom zoo ntawm txheej txheej.
