Hom Inks Feem ntau siv rau hauv Silk Screen Printing ntawm Cov Tshuaj Txhuam Hniav

Vim yog cov ntaub ntawv luam ntawv sib txawv thiab cov txheej txheem luam ntawv, qhov yuav tsum tau ua rau tus number case siv hauv kev tshuaj ntsuam iav luam ntawv kuj txawv.

Ua ntej tshaj plaws, qhov tseem ceeb tshaj plaws hauv iav luam ntawv yog txhawm rau ntxiv dag zog rau kev sib txuas ntawm tus number case thiab iav nto, kom tus number case tsis poob los yog yaj thaum siv cov khoom iav.

Thib ob, lub vijtsam iav luam ntawv yog qhuav ntawm qhov kub thiab txias, yog li tus number case siv yog tus number case kub resistant. Cov inks siv rau iav npo luam ntawv feem ntau suav nrog cov hauv qab no:

1. iav glaze

Raws li qhov kub thiab txias, cov xim glaze tuaj yeem muab faib ua peb hom: kub kub, nruab nrab kub thiab qis kub. Ntawm lawv, qhov kub tsis tshua muaj (550 degree) xim glaze yog tsuas yog siv rau kev kho kom zoo nkauj ntawm thinner iav fwj; qhov nruab nrab kub (580 degree) xim glaze yog dav siv hauv cov fwj tshuaj pleev ib ce thiab iav fwj. Kev luam ntawv ntawm cov khoom iav xws li khob; qhov kub siab (600 degree) xim glaze yog tsuas yog siv rau kev luam ntawv ntawm lub raj mis haus. Vim tias cov xim glaze muaj cov hlau lead hnyav, peb yuav tsum xyuam xim rau kev xaiv cov xim zoo tshaj plaws, tshwj xeeb tshaj yog cov ntim khoom noj.

2. UV iav number case

Qhov tshwm sim ntawm UV iav number case tau daws qhov teeb meem ziab ntawm iav npo luam ntawv mus rau qhov loj, tab sis nws yuav tsum tau muab sau tseg tias kev kho ntau dhau yuav ua rau embrittlement ntawm tus number case zaj duab xis thiab txo cov adhesion ntawm cov number case txheej.

3. Ob-kua reactive iav number case

Hom cwj mem no yog siv rau kev luam ntawv ntawm qee lub khob ntim me me xws li cov fwj tshuaj pleev ib ce, thiab lwm yam. Nws tau npaj rau ntawm qhov chaw thaum siv, thiab lub sijhawm cia yuav tsum tsis txhob ntev dhau, kom tsis txhob muaj cov khoom pov tseg los ntawm cov tawv tawv. ntawm qhov sib txuas ntawm tus cwj mem.

4. Tshwj xeeb iav number case rau thermosetting

Cov number case no yog rau volatilization drying number case, uas tuaj yeem qhuav tom qab muab tso rau hauv chav sov li 10 mus rau 15 feeb. Tsis tas li ntawd, txhawm rau txhim kho lub zog ntawm tus cwj mem zaj duab xis thiab nws cov adhesion, nws yuav tsum tau ci ntawm qhov kub ntawm 180 degree rau 10 feeb.

5. Iav pigment number case

Cov iav pigments muaj cov hmoov uas tsis muaj melting iav, thiab siv cov binders (synthetic resins thiab organic solvents) los kho cov luam ntawv ntawm tus number case, tab sis tus number case no tsis muaj xim nruab nrab. Tom qab tus number case no tau luam tawm, nws yog sintered nyob rau hauv lub qhov cub cua sov, kom cov binder nyob rau hauv tus number case yog evaporated, thiab cov iav hmoov yog softened thiab tsau rau ntawm iav nto tom qab hlawv.

Lub binder ntawm tus number case yog tsuas yog hluavtaws cob thiab organic hnyav. Lub hauv paus yuav tsum tau rau lub binder yog tias nws muaj peev xwm ua kom tiav cov evaporation, sublimation thiab combustion txheej txheem ntawm qhov kub thiab txias, thiab zam lub residue ntawm lub binder thaum lub iav hmoov yog melted. Txwv tsis pub, qhov chaw luam ntawv yuav puas. Ua npuas ncauj thiab poob smoothness.

6. Cov kua kub kub, kua nyiaj thiab kub muab tshuaj txhuam

Iav number case yog tsim los ntawm ntau yam hlau organic tebchaw ua lub ntsiab tivthaiv ntxiv rau cov ntawv khi ntawm tus number case. Cov hlau organic tebchaw siv feem ntau yog hlau-sulfide turpentine, hlau-mercaptan, thiab lwm yam. Cov nyiaj ua kua kuj muaj tib cov organic tebchaw. Nyob rau hauv cov xim kub paste, vim hais tias cov ntsiab lus ntawm kub thiab nyiaj yog heev me me, nws yog tseem siv tau raws li luam ntawv number case.
