Waterborne Fluorocarbon Txheej Systems

Cov txheej txheem dej-raws li fluorocarbon txheej siv cov khoom zoo fluorinated acrylic emulsion, uas, nrog nws cov kev ua tau zoo tshwj xeeb, muab cov txheej txheem nrog cov huab cua tshwj xeeb, tsis muaj zog, thiab tshuaj lom neeg. Cov txheej txheem no tuaj yeem tsim cov xim ruaj khov thiab cov xim hlau xim. Cov xim hlau txheej, ua tiav los ntawm kev ntxiv cov xim hlau tshwj xeeb thiab cov khoom siv ntxiv, muab cov yeeb yaj kiab zoo nkauj zoo nkauj. Nws yog qhov zoo tagnrho rau cov ntaub thaiv phab ntsa ntawm cov tsev ua haujlwm high-end, cov tsev so ua lag luam, thiab lwm lub tsev uas yuav tsum tau kho kom zoo nkauj. Huike dej-raws li fluorocarbon cov xim pleev xim yog tiv taus cov kua qaub los nag, ntsev pos huab, thiab muaj kev tiv thaiv huab cua ntev. Cov xim zaj duab xis muaj cov dej zoo tiv thaiv kab mob, kev tu tus kheej, thiab kev txhuam zoo. Nws kuj muaj zog adhesion thiab siab sib txuas lub zog.

Theem: Coarse putty: 2-3 coats, embedding mesh, 4-5 kg ​​/ m² Fine putty: 1-2 coats, 1 kg / m²

Base tsho: Sab nrauv phab ntsa anti-alkali pob tshab primer: 1 lub tsho tiv no, 0.10 kg / m²

polishing: Dej-raws li polishing putty: 1 lub tsho tiv no, 0.15 kg / m²

Intermediate tsho tiv no: Water-based fluorocarbon elastic intermediate tsho: 1 lub tsho, 0.20 kg / m²

Lub tsho sab saum toj: Dej-raws li fluorocarbon hlau xim: 2 lub tsho, 0.20 kg / m²

Clear Coat (yeem): Water-based fluorocarbon clear varnish: 1 lub tsho, 0.10 kg/m²

Theem: Siv cov coarse putty nrog trowel rau thawj lub tsho tiv no. Ua ntej qhov chaw dries, siv lub scraper kom du nws tawm thiab kho nws vertically. Tom qab ziab, siv ob lub tsho tiv no ntawm coarse putty, embedding lub mesh. Xyuas kom lub ntsej muag du, tsis muaj wrinkles lossis qhov chaw raug.
Thaum lub coarse putty qhuav, siv 1-2 lub tsho tiv no ntawm fine putty. Tom qab qhov chaw dries, siv lub tshuab sanding nrog 240-grit sandpaper kom du nto. Qhov yuav tsum tau flatness yog ≤1mm.

Base tsho: Do cov phab ntsa sab nrauv los tiv thaiv alkali pob tshab primer sib npaug ua ntej siv. Yog xav tau kev hloov viscosity, ntxiv ≤20% dej huv rau dilution.
Siv cov primer npaj nrog wool roller. Rau cov ces kaum thiab qhov khoob, pab daim ntawv thov nrog cov ntaub plaub txhuam. Xyuas kom cov tuab tuab, tsis muaj qhov tsis pom, lossis pom cov substrate.

polishing: Do cov dej-raws li polishing putty tusyees ua ntej siv. Yog xav tau kev hloov viscosity, ntxiv ≤5% dej huv rau dilution.
Siv lub npaj putty nrog ib tug trowel. Xyuas kom cov tuab tuab, thiab tom qab ziab, siv lub tshuab xuab zeb nrog 600-grit sandpaper kom du nto. Qhov yuav tsum tau flatness yog ≤1mm.

Intermediate tsho tiv no: Do cov dej-raws li fluorocarbon elastic intermediate tsho tiv no tusyees ua ntej siv. Yog xav tau kev hloov kho viscosity, ntxiv ≤5% dej huv rau dilution.Tau lub tsho loj nruab nrab nrog rab phom tsuag. Xyuas kom cov tuab tuab, tsis muaj qhov tsis pom, lossis pom cov substrate.

Lub tsho sab saum toj: Do cov dej-raws li fluorocarbon hlau xim sib npaug ua ntej siv. Yog xav tau kev hloov kho viscosity, ntxiv ≤10% dej huv rau dilution.Tau lub tsho tiv no nrog rab phom tsuag hauv 2 lub tsho, nrog lub sijhawm rov txheej txheej ntawm ≥2 teev. Xyuas kom cov tuab tuab, tsis muaj qhov tsis pom, pom cov substrate, lossis streaking.

Clear Coat: Cov dej-raws li fluorocarbon cov kua roj vanish tuaj yeem siv tau raws li tus neeg siv khoom lossis cov qauv xav tau.Kho cov dej-raws li fluorocarbon ntshiab kua roj vanish sib npaug ua ntej siv. Yog xav tau kev hloov kho viscosity, ntxiv ≤20% dej huv rau dilution.Thov cov kua roj vanish uas npaj fluorocarbon ntshiab nrog rab phom tsuag hauv 1 lub tsho. Xyuas kom cov tuab tuab, tsis muaj qhov tsis pom, lossis pom cov substrate.
