Siav tung roj yog zoo thiab dries sai sai, tab sis raw tung roj yuav tsum tau boiled.Siav tung roj yog qhov zoo tshaj plaws diluted nrog turpentine.Ntoo sab nraum zoov tsis yooj yim rau rot thaum txhuam nrog tung roj.Turpentine suav txog li 30% ntawm tag nrho cov feem.Turpentine yog muab rho tawm los ntawm cov ntoo ntoo, thiab cov qib ntawm kev tiv thaiv ib puag ncig yog qhov zoo.Tung roj tsis yog tshwj xeeb yog noj tau zoo li cov roj pleev xim, tom qab tau coated nrog cov roj tungs, cov yeeb yaj kiab tiv thaiv yuav tsim rau ntawm cov ntoo, uas yog airtight, yog li ua rau cov dej tsis zoo.Tsis tas li ntawd, yog tias cov roj tung feem ntau raug muab tshem tawm nrog cov ntaub paj rwb huv, nws tsis txhuam nrog txhuam, thiab cov txhuam hniav yuav tawm los ua haujlwm tsis zoo.
Uas yog zoo dua rau sab nraum zoov siv quav ciab roj los yog kua roj vanish
txhua yam zoo.
1. Los ntawm kev xav ntawm cov khoom xyaw, cov khoom siv raw ntawm cov roj siv roj yog feem ntau cov xim ntuj, cov roj zaub, thiab lwm yam, thiab tsis muaj cov khoom xyaw lom, thaum cov kua roj vanish muaj qee cov kua roj vanish, uas muaj qee yam tshuaj lom neeg.Nyob rau hauv cov nqe lus ntawm kev ua tau zoo, ntoo ciab roj muaj zoo waterproof thiab anti-fouling zog, hnav tsis kam thiab txhuam tsis kam, thiab yog haum rau sab hauv tsev thiab sab nraum zoov siv, thaum cov kua roj vanish muaj zoo dej kuj, tab sis nws tsis tuaj yeem siv rau hauv qhov chaw ntub dej.
2. Tom qab cov kua roj vanish anti-cracking yog pleev xim rau, ib tug tuab xim zaj duab xis yog tsim nyob rau saum npoo ntawm cov khoom ntoo.Cov xim pleev xim tuaj yeem cais cov dej noo hauv huab cua, muaj kev tiv thaiv zoo thiab tiv thaiv corrosion, thiab muaj qee qhov kev hnav tsis kam.Tsis tas li ntawd, txij li cov kua roj vanish yog ob qho tib si thiab muaj qee tus nqi ntawm cov tshuaj tua kab mob, nws dries sai dua.
Sab nraum zoov anti-corrosion ntoo txhuam ntoo wax roj los yog kua roj vanish yog zoo dua
Sab nraum zoov anticorrosive ntoo xim tseem hu ua ntoo ciab roj.Ntoo wax roj yog ib lub npe nrov hauv Suav teb rau zaub roj ciab xim.Nws yog cov xim ntoo uas zoo ib yam li cov xim tab sis txawv ntawm cov xim.
Nws muaj cov yam ntxwv hauv qab no:
1. Super muaj zog nkag tau lub zog thiab adhesion, nws tuaj yeem tsim cov nyhuv capillary nrog ntoo thiab ua kom muaj kev sib xyaw ua ke ntev.
2. Ntoo tuaj yeem ua pa dawb, tswj cov av noo, elasticity, thiab ncua deformation.
3. Antistatic, tsis muaj teeb meem rau tib neeg lub cev, thiab tuaj yeem tiv thaiv plua plav zoo.
4. Teeb pom kev zoo nkauj ntawm cov ntoo.
5. Zoo repeatability thiab yooj yim txij nkawm.
6. Tsis muaj ntxhiab tsw tom qab ziab.
Puas yog cov roj ntoo zoo dua lossis cov kua roj vanish zoo dua?
Ntoo roj yog ib hom ntoo txheej zoo ib yam li cov xim tab sis txawv ntawm cov xim.Cov khoom yog tsim los ntawm refined linseed roj, xibtes wax thiab lwm yam ntuj zaub roj, zaub ciab thiab lwm yam khoom xyaw ntuj.Cov kua roj vanish, tseem hu ua kua roj vanish, yog txheej txheej ntawm cov resin ua cov yeeb yaj kiab tseem ceeb thiab cov kuab tshuaj.
Cov xim dab tsi zoo rau cov ntoo sab nraum zoov?
Nws yog qhov zoo tshaj plaws los siv ntoo lacquer rau Suav fir, nyob ntawm seb lub hom phiaj ntawm Suav fir.
Cov xim ntoo yog hais txog ib hom xim xim siv rau cov khoom siv ntoo, nrog rau polyester, polyurethane xim, thiab lwm yam, uas tuaj yeem muab faib ua dej thiab roj.Raws li gloss, nws tuaj yeem muab faib ua siab gloss, semi-matte thiab matte.Raws li daim ntawv thov, nws tuaj yeem muab faib ua cov xim rooj tog, xim hauv pem teb thiab lwm yam.
