Muaj pes tsawg leeg ntawm cov mineral ntsuj plig. Dawb ntsuj plig: yam ntxwv

Dawb ntsuj plig - ib tug tshwj xeeb neeg sawv cev (kuab), uas yog npaj rau dilute lub ntau yam kua alkyds, tej hom ntawm roj hmab (yeej, nws yuav ua tau butyl thiab cyclohexyl), thiab polybutylmethacrylate. Nyob rau hauv tas li ntawd, thaum cov ntsiab lus nyob rau hauv nyob tus yeees ntawm cov kho cov ntaub ntawv uas epoxy esters, active ntsuj plig thiab muaj peev xwm ntawm dissolving nws. Vim li cas siv dawb ntsuj plig, yuav ua li cas thov nws, ua li cas nws yog thauj thiab dab tsi yog raug? Cov lus teb rau tag nrho cov lus nug thiab ntau ntau yuav kawm nyob rau hauv lub chav kawm ntawm kev nyeem ntawv no tsab xov xwm.

kheej ntawm daim ntawv thov

Feem ntau, dawb ntsuj plig kuab siv los dilute cov roj varnishes thiab muab cov tshuaj uas muaj npe nyob rau hauv lub yav dhau los cov pawg lus. Qhov cuab yeej no yog siv los mus nto degreasing thiab ntxuav lub saum npoo ntawm cov khoom, qhov chaw thiab cov cuab yeej. koj nug -, "Koj dawb ntsuj plig Degreases zoo." Xws li ib tug kuab vim nws pheej thiab txhoj puab heev muaj pes tsawg leeg, uas peb yuav xav txog rau yav tom ntej, yog tau yaj txawm lub toughest tshuaj, yog li ntawd thaum koj ua hauj lwm nrog nws koj yuav tau saib xyuas ntawm lub ntxiv txhais tau tias ntawm kev tiv thaiv.

Tiam sis rov qab mus rau lub daim ntawv thov. Nyob rau hauv tas li ntawd mus rau lub degreasing, yog ib lub yam ntxwv tseem ceeb ntawm no hom ntawm kuab yog dilution gustotertyh thiab cov pa roj-raws li xim tsev, nyeem tas txha hniav laus thiab ntau lwm yam ntau ntau yam thiab hom ntawm cov xim tsev. Nyob rau hauv tas li ntawd, lub dawb ntsuj plig muaj peev xwm sawv ntawm dissolving ib tug txheej ntawm nyeem tas primers, varnishes, bituminous cov ntaub ntawv thiab lwm yam. Thiab nyob rau hauv thiaj li hais tias lub txiaj ntsim ntawm kev ua hauj lwm ua tau kev txaus cai lawv xav, kws txawj pom zoo ntxuav txhuam thiab chais nyob rau hauv lub kuab txawm ua ntej thov kev pab rau lawv alkyd, roj thiab pentaphthalic enamels. Dawb ntsuj plig yog feem ntau siv nyob rau hauv qhov kev lag luam raws li ib tug degreasing caij siv ua ntej painting ntawm hlau thiab hlau lug.

Tab sis nyob rau hauv lub neej txhua hnub nws yog tsis muaj tsawg ceev. Cov ua liaj ua teb dawb ntsuj plig yog siv raws li ib tug hnyav rau ntau yam bitumen thiab roj.
