Raws li qhov nyuaj ntawm cov khoom hloov pauv thiab cov qauv, muaj ntau hom thiab specifications ntawm dej hloov zaj duab xis xaiv los ntawm. Cov yeeb yaj kiab no feem ntau yog tsim los ntawm cov substrates tshwj xeeb xws li polyvinyl cawv (PVA), nrog cov yeeb yuj thiab cov qauv zoo nkauj luam tawm ntawm qhov chaw. Thaum lub sijhawm hloov cov txheej txheem, cov yeeb yaj kiab hloov dej yuav tsum tau yooj yim sib cais hauv dej thiab xyuas kom meej tias cov qauv tseem nyob ruaj khov thiab meej thaum hloov mus rau qhov chaw ntawm cov khoom.
2. Ua kom tus neeg ua haujlwm
Activating agents yog cov tshuaj reagents tseem ceeb hauv cov txheej txheem luam ntawv hloov dej. Nws lub luag haujlwm tseem ceeb yog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau ua tiav cov txheej txheem dej, nws, nws raug nquahu kom siv cov txheej txheem sib cais ntawm cov txheej txheem ntawm cov txheej txheem. Kev xaiv thiab siv cov activators yuav tsum tau tswj nruj me ntsis kom ntseeg tau tias muaj kev sib cais ntawm cov qauv txheej txheem yam tsis muaj kev puas tsuaj rau tus qauv nws tus kheej lossis qhov chaw ntawm cov khoom. Tsis tas li ntawd, qhov volatility thiab ib puag ncig tus phooj ywg ntawm activators kuj tseem ceeb rau kev txiav txim siab thaum xaiv.
3. Primer
Primer yog ib qho tseem ceeb ntawm cov txheej txheem ua ntej kev kho cov dej hloov luam ntawv. Nws yog coated rau saum npoo ntawm cov khoom yuav tsum tau hloov, siv los txhim kho qhov adhesion ntawm cov khoom nto thiab nteg lub hauv paus ruaj khov rau kev ua haujlwm tom ntej. Kev xaiv ntawm primer yuav tsum sib txawv nyob ntawm seb cov khoom ntawm cov khoom los xyuas kom meej tias nws muaj peev xwm tsim ib tug zoo daim ntawv cog lus nrog rau saum npoo ntawm cov khoom yam tsis muaj kev cuam tshuam cov adhesion nyhuv ntawm cov dej hloov zaj duab xis. Tom qab siv cov primer, nws yog feem ntau yuav tsum tau qhuav nws kom tshem tawm cov kuab tshuaj thiab txhim kho adhesion.
4. Cov tshuaj ntxuav tu
Cov tshuaj ntxuav tu yog siv los ntxuav tom qab dej hloov luam ntawv. Thaum lub sij hawm hloov luam ntawv, tej zaum yuav muaj residual activators, dej hloov zaj duab xis fragments, los yog lwm yam impurities nyob rau saum npoo ntawm cov khoom. Cov neeg ua haujlwm tu tuaj yeem tshem tawm cov khoom seem no tau zoo, rov ua kom lub ntsej muag ntawm cov khoom kom zoo thiab npaj nws rau kev pleev xim tom ntej lossis kev tiv thaiv kev kho mob. Kev xaiv cov neeg ua haujlwm tu yuav tsum xyuas kom meej tias lawv tuaj yeem tshem tawm cov khoom seem sai sai thiab tsis muaj kev puas tsuaj rau qhov chaw ntawm cov khoom lossis cov qauv hloov pauv.
5. Cov xim tiv thaiv (gloss oil)
Cov xim tiv thaiv yog ib yam khoom tseem ceeb hauv cov kauj ruam tom qab kho cov dej hloov luam ntawv. Nws yog coated rau saum npoo ntawm cov qauv hloov mus txhim khu nws hnav tsis kam, huab cua tsis kam, thiab glossiness. Muaj ntau ntau hom tshuaj tiv thaiv, nrog rau cov kua roj vanish raws li cov kua roj vanish, UV kua roj vanish, thiab lwm yam. Cov xim sib txawv ntawm cov xim tiv thaiv muaj cov yam ntxwv sib txawv thiab siv, thiab cov neeg siv tuaj yeem xaiv cov xim tiv thaiv tsim nyog raws li lawv cov kev xav tau tshwj xeeb. Tom qab siv cov xim tiv thaiv, nws yog ib qho tsim nyog yuav tsum tau ua kev kho mob (xws li ntuj ziab, cua kub kom qhuav, lossis UV kho) kom ntseeg tau tias nws tuaj yeem ua raws li qhov chaw ntawm cov khoom thiab tsim cov txheej txheem tiv thaiv.
6. Cov cuab yeej pabcuam thiab khoom siv
Ntxiv nrog rau cov ntaub ntawv tseem ceeb uas tau hais los saum toj no, cov cuab yeej pabcuam thiab cov cuab yeej txhawb nqa kuj tseem yuav tsum tau ua thaum lub sijhawm luam ntawv hloov dej. Cov cuab yeej thiab cov cuab yeej siv no suav nrog:
Sink: Siv los tuav cov yeeb yaj kiab hloov dej thiab cov khoom xa mus, tso cai rau lawv hloov cov qauv hauv dej.
Txau phom los yog txhuam: siv los ua kom sib npaug ntawm cov tshuaj tua kab mob los yog ntxuav cov khoom ntawm cov khoom thaum lub sij hawm hloov luam ntawv.
Cov cuab yeej ziab khaub ncaws: xws li cua kub tshuab ziab khaub ncaws lossis qhov cub, siv rau ziab primer thiab tiv thaiv xim.
Cov cuab yeej txheej: xws li rab phom, txhuam hniav, los yog cov chais, siv rau kev siv cov primer thiab cov xim tiv thaiv.
Fixtures thiab kho cov cuab yeej: siv los kho cov khoom kom raug xa mus los tiv thaiv kev txav los yog deformation thaum lub sijhawm hloov pauv.
