Cov muaj pes tsawg leeg, kev ua tau zoo thiab kev siv yog txawv<&list>Cov muaj pes tsawg leeg yog txawv: enamels yog pigments thiab resins, xim yog resins, fillers, pigments, thiab ib co kuab tshuaj thiab additives yog ntxiv.<&list>Qhov kev ua tau zoo sib txawv: enamel muaj qhov kub thiab txias tsis kam, adhesion, thiab zoo dua gloss, thiab tuaj yeem tiv taus kev hloov pauv huab cua.Cov xim yog soluble hauv kerosene, roj av, thiab lwm yam, tab sis insoluble hauv dej.Nws muaj qhov zoo nkauj zoo nkauj thiab muaj xim nplua nuj.<&list>Kev siv sib txawv: Enamel xim yog dav siv los pleev xim rau hauv tsheb lossis hlau, thiab xim feem ntau yog pleev xim rau ntawm phab ntsa, rooj tog, tsheb, steel ncej, thiab lwm yam.
Muaj ntau hom xim ntawm lub khw, xws li: enamel, xim, xim latex, kua roj vanish, thiab lwm yam. Ntau hom muaj cov khoom sib txawv thiab kev siv ntau yam.Yog li dab tsi yog qhov txawv ntawm enamel thiab xim?
1. Qhov txawv ntawm enamel thiab xim yog dab tsi
1. Cov khoom xyaw sib txawv: Cov khoom tseem ceeb ntawm cov enamel yog cov pigments thiab resins, thiab qee cov enamel kuj tseem yuav ntxiv qee cov phenolic formaldehyde.Muaj ntau lub ntsiab ntawm cov xim, xws li: resins, fillers, pigments, thiab ib co kuab tshuaj, additives, thiab lwm yam.
2. Cov khoom sib txawv: enamel tsis tsuas yog muaj qhov kub thiab txias ua haujlwm zoo, tab sis kuj muaj qhov zoo dua gloss, thiab tuaj yeem tiv taus kev hloov pauv huab cua.Cov xim yog soluble hauv kerosene, roj av, thiab lwm yam, tab sis tsis yog dej-soluble, thiab muaj cov nyhuv zoo nkauj, thiab ntau yam xim kuj nplua nuj.
3. Kev siv sib txawv: Cov xim enamel tuaj yeem ntxiv nrog qee cov xim tsim nyog raws li kev tsim kho, thiab siv dav siv los pleev xim rau hauv tsheb lossis hlau.Cov xim feem ntau yog pleev xim rau ntawm phab ntsa, rooj tog, tsheb, steel thav duab, thiab lwm yam, tsis tsuas yog tuaj yeem ua lub luag haujlwm ntawm cov dej tsis zoo, roj pov thawj, tiv thaiv corrosion, thiab lwm yam, tab sis kuj muaj cov nyhuv zoo nkauj heev.
Qhov thib ob, yam dab tsi yuav tsum tau them nyiaj rau hauv kev tsim kho cov xim enamel
1. Thaum lub sij hawm tsim kho txheej txheem ntawm enamel xim, enamel xim feem ntau yuav tsum tau siv ntau tshaj ob zaug, thiab sanding yuav tsum tau nqa tawm ua ntej txhua txoj kev tsim kho, lub hom phiaj yog ua kom cov adhesion ntawm txhua txheej ntawm cov xim zaj duab xis, yog tias cov neeg ua haujlwm tsim kho. tsis loj Yog tias sanding, nws yuav ua rau cov adhesion ntawm cov txheej tom ntej ntawm cov xim zaj duab xis txo.
2. Thaum lub sij hawm tsim kho, nws yog ib qho tsim nyog yuav tsum ua raws li cov txheej txheem tsim kho kom raug, kom tsis txhob muaj kev cuam tshuam rau kev tsim kho thiab kev pab cuam lub neej ntawm cov xim pob zeb.Nyob rau hauv ib txwm muaj xwm txheej, lub substrate yuav tsum tau kho ua ntej, ces lub phab ntsa saum npoo yuav tsum tau muab kaw, ces putty yuav tsum tau siv, primer yuav tsum tau siv, leveling yuav tsum tau nqa tawm, thiab topcoat yuav tsum tau siv thaum kawg.
