Dab tsi txheej tuaj yeem ua tiav lub tsho tiv no xim besmear board yog siv tom qab lub sijhawm, vim tias muaj kev cuam tshuam los ntawm txhua yam ntawm ib puag ncig, nws cov cuab yeej besmear zaj duab xis thiab lub neej kev pab cuam tuaj yeem txo, yuav tsum tau lees paub repaint rau nws.Qhov tseem ceeb tshaj plaws uas yuav tsum tau ua rau cov txheej txheej repainted yog kom muaj qee qib ntawm adhesion nrog cov txheej txheem qub, thiab ua kom zoo dua qub.Sab nraum zoov xim coated board raws li kev siv ntawm ib puag ncig tuaj yeem muab faib ua peb pawg, thawj qeb, kev siv nyob rau hauv ib puag ncig ntuj, cov kev xav tau ntawm qee yam kev tiv thaiv corrosion.Xws li: qhov chaw tsim kho, siv cov xim coated board cais;Chav Kawm 2, siv nyob rau hauv tej yam ntuj tso ib puag ncig, muaj ib tug tej yam corrosion tiv thaiv thiab tsos nyhuv.xws li: nyob rau hauv lub sab nraum zoov kev tsim kho ntawm mobile board tsev;Cov qeb thib peb, siv nyob rau hauv qee qhov chaw hnyav, yuav tsum muaj qee tus lej ntawm kev tiv thaiv lub neej.
Adhesive quab yuam ntawm cov xim sib txawv coated daim hlau los txiav txim siab txheej txheej rau cov xim coated daim hlau.Polyester amino system txheej txheej txheej muaj ntau ntawm hydroxyl thiab amino pawg, thiab lub tsev xim txheej phaj yog feem ntau semi-optical txheej, txheej muaj ntau cov fillers los yog matting hmoov, micro nto nthuav tawm qee yam roughness, yooj yim thiab kho. txheej ntawm pab pawg hydrogen bonding thiab doxtail wedge nyhuv, yog li cov adhesion muaj zog.
Raws li cov txheej txheem ntub dej saum npoo, qhov nro ntawm qhov kev xaiv kho txheej yuav tsum qis dua qhov nro ntawm cov xim topcoat rau ntub dej;Kev kho cov txheej txheem yuav tsum muaj pawg polar uas tuaj yeem tsim cov ntawv cog lus hydrogen;Kho cov xim kom muaj cov kuab tshuaj muaj zog tuaj yeem ua rau cov xim o, txhawm rau txhim kho cov adhesion ntawm cov khaubncaws sab nraud povtseg;Nyob rau tib lub sijhawm, cov txheej txheem tuaj yeem siv los txo qis tus txheeb ze molecular hnyav ntawm cov resin los yog txo cov viscosity ntawm txheej, siv cov kuab tshuaj qeeb qeeb thiab qis dua tus nqi sib txuas ntawm cov txheej los txhim kho nws cov adhesion ntawm cov xim txheej. phaj.
