Cov Lus Cim Ntawm Cov Hnab Luam Ntawv

Raws li ib qho kev txhawb nqa thiab kev tiv thaiv cov khoom lag luam, cov hnab tes tsis yog tsuas yog muab kev yooj yim rau cov neeg yuav khoom, tab sis kuj yog lub sijhawm los txhawb cov khoom lossis cov khoom lag luam dua. Txawm hais tias muaj ntau yam ntawm nws, feem ntau ntawm lawv yog cov duab plaub thiab muaj cov qauv zoo sib xws. Feem ntau, offset printing tshuab yog siv los ua kom tiav cov luam ntawv. Hauv qab no, peb yuav qhia txog kev ceev faj rau kev luam ntawv:
1. Thaum lub sij hawm luam ntawv, vim yog cov dej volatilization, viscosity ntawm number case tuaj yeem nce thiab pH tus nqi tuaj yeem txo. Tus nqi pH feem ntau yuav tsum tau tswj ntawm 8.5 thiab 9.5, thiab pH stabilizers tuaj yeem siv los kho nws kom muaj kev ruaj ntseg ntawm viscosity thiab pH.
2. Thaum siv tus cwj mem rau luam ntawv hnab, siv tus pas txhuam txhuam kom nplawm tus number case sib npaug hauv lub thoob, ntsuas nws cov viscosity, thiab muab tso rau hauv lub tank. Yog tias qhov viscosity siab dhau lossis qis dhau, cov diluents lossis thickeners tuaj yeem ntxiv rau kev hloov kho.
3. Vim lub fact tias tus number case yog ib tug ntshiab dej-raws li system, nws yog advisable kom tsis txhob sib tov tus number case nrog cawv raws li inks thiab hnyav raws li tus number case los yog ntxiv cov kuab tshuaj rau tus number case thaum luam ntawv kom tsis txhob muaj teeb meem luam ntawv zoo.
4. Tus number case rau luam ntawv yuav tsum muab cia rau hauv tsev, nrog rau chav tsev kub feem ntau ntawm 5 ° C thiab 50 ° C.
5. Kev luam ntawv tsim nyog ntawm tus number case yog cuam tshuam los ntawm lub hom phiaj xwm txheej xws li luam ntawv, cov yam ntxwv ntawm lub substrate, ib puag ncig kub thiab av noo, thiab lub sijhawm ntev ntawm tus number case cia. Yog li ntawd, thaum siv tus number case rau luam ntawv, nws yog ib qho tsim nyog yuav tsum tau siv qee cov tshuaj ntxiv los ua kom hloov me ntsis rau tus cwj mem kom ua tiav cov txiaj ntsig luam ntawv zoo dua.
Kev siv tus cwj mem yog qhov tseem ceeb heev hauv cov txheej txheem luam ntawv ntawm cov hnab tes, thiab txhua tus neeg yuav tsum tau xyuam xim thaum siv nws.
