Nyob rau hauv lub sij hawm ntev luam ntawv, tus number case maj poob nws fluidity, thiab viscosity nce txawv txav, uas ua rau tus number case jelly zoo li, tom qab siv cov residual number case yog nyuaj dua.
Yog vim li cas txawv txawv:
1, Thaum cov kuab tshuaj nyob rau hauv cov luam ntawv number case yog volatilized, cov dej lwg generated los ntawm sab nraud uas tsis muaj kub yog tov rau hauv cov luam ntawv number case (tshwj xeeb tshaj yog yooj yim tshwm sim nyob rau hauv lub chav tsev uas noj cov printing number case yog heev me me).
2, Thaum tus number case nrog siab affinity nrog dej yog siv, tus number case tshiab yuav thicken txawv txav.
Kev daws:
1, Cov kuab tshuaj kom qhuav sai yuav tsum tau siv ntau li ntau tau, tab sis qee zaus cov dej me me yuav nkag mus rau hauv cov ntawv luam tawm thaum qhov kub thiab txias. Yog tias muaj qhov txawv txav tshwm sim, tus number case tshiab yuav tsum tau muab ntxiv lossis hloov lub sijhawm. Cov kua nplaum uas siv ntau zaus yuav tsum tau lim los yog muab pov tseg tsis tu ncua vim muaj kev cuam tshuam ntawm dej thiab hmoov av.
2, Sib tham txog qhov txawv txav nrog cov neeg tsim khoom siv number case, thiab txhim kho tus cwj mem yog tias tsim nyog.
Cov ntxhiab tsw (solvent residue): Cov kuab tshuaj organic hauv cov ntawv luam ntawv feem ntau yuav qhuav nyob rau hauv lub tshuab ziab khaub ncaws tam sim ntawd, tab sis cov residual trace solvent yuav solidified thiab xa mus rau thawj zaj duab xis kom nyob twj ywm. Tus nqi ntawm high-concentration organic solvent residues nyob rau hauv cov ntawv luam tawm ncaj qha txiav txim qhov tsw ntawm cov khoom kawg. Txawm hais tias nws txawv txav tuaj yeem txiav txim los ntawm kev hnov qhov ntswg. Tau kawg, nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, kev hnov tsw ntawm lub qhov ntswg tau poob qis heev. Rau cov khoom uas xav tau ntau dua rau cov kuab tshuaj residue, cov cuab yeej tshaj lij tuaj yeem siv los ntsuas lawv.
Yog vim li cas txawv txawv:
1, Printing ceev ceev heev
2, Inherent zog ntawm resins, additives thiab binders nyob rau hauv printing inks
3, Kev ziab kom qhuav yog tsawg dhau los yog tsis muaj txoj kev ziab
4, Cov pa cua yog thaiv
Kev daws:
1. Tsim nyog txo qhov nrawm ntawm kev luam ntawv
2. Qhov teeb meem ntawm residual solvent nyob rau hauv printing number case tuaj yeem sib tham nrog tus neeg tsim khoom kom ceev faj. Kev siv cov kuab tshuaj kom qhuav sai tsuas yog ua rau cov kuab tshuaj evaporate sai, thiab tsis muaj kev cuam tshuam ntau npaum li cas ntawm cov kuab tshuaj residual.
3. Siv cov kuab tshuaj kom qhuav sai los yog qhov kub thiab txias kom qhuav (ua kom qhuav sai yuav ua rau lub ntsej muag ntawm tus number case crusted, uas yuav cuam tshuam rau cov evaporation ntawm cov kuab tshuaj sab hauv. Slow-drying zoo txo cov seem ntawm cov kuab tshuaj.)
4. Txij li thaum cov residual organic hnyav kuj muaj feem xyuam rau hom ntawm thawj zaj duab xis, tus nqi ntawm cov residual hnyav nws txawv nrog rau hom ntawm cov thawj zaj duab xis. Thaum tsim nyog, peb tuaj yeem tham txog qhov teeb meem ntawm cov kuab tshuaj residue nrog cov thawj zaj duab xis thiab number case manufacturers.
5. Tsis tu ncua ntxuav cov pa cua kom ua kom nws tso pa tawm zoo
