Siv dav ua lub hauv paus rau cov khoom ntoo, kuj tseem siv tau los hloov kho roj xim thiab ua kom muaj zog.
(5) Nws cov xim sib xyaw
Kev pleev xim sib xyaw, tseem hu ua cov xim sib xyaw, yog feem ntau siv cov xim pleev xim thiab yog rau qeb ntawm cov tha xim yeeb yam. Nws yog ib qho yog ua los ntawm cov roj kom qhuav thiab cov xim raws li cov khoom siv raw, yog li nws yog hu ua cov roj-raws li cov xim sib xyaw. Cov xim sib tov muaj cov yam ntxwv ntawm kev ci, du, zoo ib yam, zoo ib yam li ceramic lossis enamel nyob rau hauv tsos, xim xim thiab muaj zog adhesion. Txhawm rau kom tau raws li cov kev xav tau sib txawv, cov kev sib txawv ntawm cov txiv ntoo uas muaj ntau ntxiv rau cov xim sib xyaw, yog li tsim cov nyhuv ib nrab lossis matte.
Cov xim sib tov yog qhov haum rau sab hauv tsev thiab sab nraum zoov, ntoo, silicon phab ntsa deg. Hauv kev kho kom zoo nkauj sab hauv, xim sib nqus yog nrov dua vim tias nws cov txiaj ntsig zoo nkauj thiab du thiab huab cua tsis tsawg tshaj li cov xim sib xyaw. Raws li lub ntsiab Resin siv nyob rau hauv cov xim, cov xim sib xyaw tuaj yeem faib ua cov xim calceed thiab txhuam cov cuab yeej, haum rau cov ntoo thiab cov tsev hlau xws li cov tuam tsev , cuab yeej, cov cuab yeej ua liaj ua teb, tsheb, rooj tog, thiab lwm yam.
(6) tiv thaiv cov xim xeb
Anti-xeb xim tshwj xeeb suav nrog zinc daj, HLUB liab Epoxy Primer, cov xim pleev xim tawv yog cov tawv thiab ruaj, zoo adhesion. Yog tias siv nrog vinyl phosphating primer, nws tuaj yeem txhim kho lub tshuab hluav taws kub, thiab yog qhov tsim nyog rau cov khoom siv hlau hauv cov ntug hiav txwv thiab huab cua sov. Anti-xeb xim yog tsuas yog siv los tiv thaiv cov khoom hlau, tiv thaiv cov xeb xeb, thiab ua kom muaj zog thiab pabcuam lub neej ntawm cov ntaub ntawv hlau.
(7) Cawv Rog Rog Rog, Acid Xim
Kev quav cawv, alkyd cov xim yaj duab siv cov kuab tshuaj organic xws li turpentine, thuv dej, roj av, acetone, etetone, etetone, ether thiab thiaj li hnov tsw phem. Saib xyuas tshwj xeeb yuav tsum tau them rau xaiv cov khoom lag luam zoo thaum siv, vim tias cov xim pleev xim no yuav muaj qee cov khoom xyaw. Tom qab siv, ncua sij hawm cua tuaj yeem kuaj xyuas kom txo tau cov kev puas tsuaj rau tib neeg lub cev. Cov xim pleev xim no feem ntau haum rau qee qhov scenes uas tsis tas yuav ua kom zoo nkauj cuam tshuam, tab sis xav tau kev tiv thaiv.
