Xim Ink, dav siv rau hauv kev luam ntawv thiab sau cov ntawv thov, yog paub rau nws cov xim muaj xim ntau thiab ua kom ntev. Tsis zoo li DEO-based inks, Xim inks muaj cov khoom seem tshem tawm hauv cov kua nruab nrab. Nkag siab txog cov txheej txheem ziab khaub ncaws ntawm cov number case no yog qhov tseem ceeb rau kev ua kom zoo nkauj luam kom zoo thiab ntev. Cov ntawv no tshawb txog qhov xwm txheej uas cuam tshuam nrog cov txheej txheem kom qhuav ntawm cov kua mem thiab thev naus laus zis siv los txhim kho nws.
Kev sib xyaw ntawm cov xim mem tes
Pigment number case yog tsim los ntawm peb yam tseem ceeb: cov xim xim, lub tsheb ua kua (kua kua lossis dej), thiab cov khoom ntxiv. Cov pigment particles muab xim, thaum lub tsheb ua kua tso cai rau tus number case ntws thiab kis rau ntawm substrate. Cov khoom siv ntxiv yog siv los txhim kho ntau yam khoom xws li lub sijhawm ziab, adhesion, thiab dej tsis kam.
Afficting
Cov txheej txheem ziab ntawm cov kua mem pa tuaj yeem tshwm sim los ntawm ntau cov txheej txheem:
1. Evaporation: Nyob rau hauv cov txheej txheem no, lub tsheb ua kua evaporates, tawm hauv qab cov pigment particles ntawm lub substrate. Qhov no yog lub tshuab ziab khaub ncaws ntau tshaj plaws rau cov kuab tshuaj raws li xim xim.
2. Kev nqus: lub substrate nqus lub tsheb kua, ua rau cov paus voos xim kom muab tso rau ntawm nws qhov chaw. Cov txheej txheem no yog feem ntau cuam tshuam rau cov kua dej hauv cov inks siv hauv cov ntawv thov nyiam luam ntawv rau ntawm daim ntawv.
3. Caum Kev Cuam Tshuam: Muaj qee kis, cov xim xim coagulate lossis sib sau ua ke thaum muaj kev sib cuag, sib sau ua yeeb yaj kiab. Qhov kev siv tshuab no feem ntau siv hauv kev tshuaj ntsuam luam ntawv nrog cov xim hlau.
Yam cuam tshuam rau lub sijhawm qhuav
Ntau yam tuaj yeem cuam tshuam lub sijhawm ziab ntawm cov xim xim:
1. Ink Formulation: Cov qauv tsim tshwj xeeb ntawm cov xim xim, nrog rau hom thiab tus nqi ntawm cov kua tsheb thiab cov khoom ntxiv, tuaj yeem cuam tshuam rau lub sijhawm ziab.
2. Substrate: cov khoom siv thiab porosity ntawm substrate tuaj yeem cuam tshuam rau nws sai npaum li cas nws nqus lossis cuam tshuam nrog lub sijhawm kom qhuav.
3. Cov xwm txheej ib puag ncig: Kub, av noo, thiab huab cua ncig tuaj yeem cuam tshuam tus nqi ntawm evaporation thiab nqus, cuam tshuam rau tag nrho cov txheej txheem ziab.
4. Printing Technology: Cov tshuab luam ntawv sib txawv (piv txwv li, inkjet, offset, screen printing) muaj ntau yam kev xav tau rau cov kua number case kom qhuav, uas tuaj yeem ua kom zoo dua los ntawm cov txheej txheem number case thiab cov ntawv luam tawm.
Txhim khu kev ua kom qhuav
Txhawm rau txhim kho qhov ziab kom qhuav ntawm cov inks inks, ntau lub tswv yim tuaj yeem ua haujlwm:
1. Ua kom ua tau zoo nyob rau hauv cov qauv: Los kho cov piv txwv rau cov khoom siv tsheb lossis kev sib xyaw ua ke kom haum rau cov ntawv thov tshwj xeeb.
2. Kev kho cov substrates ua ntej: Kev kho cov substrates ua ntej nrog cov tshuaj los yog cov tshuaj primers tuaj yeem txhim kho lawv cov kev sib raug zoo nrog cov number case, ua rau lub sij hawm kom qhuav sai.
3. Cua sov lossis UV Curing: Siv cov cua sov los yog ultraviolet (UV) lub teeb tuaj yeem ua kom cov txheej txheem kom qhuav los ntawm kev txhawb nqa evaporation lossis coagulation ntawm tus number case.
4. Txhim kho qhov cua: ua kom cov pa tau ua kom muaj kev sib tw ua kom zoo tuaj yeem pab cov evaporation explection thiab txhim kho kev ua kom qhuav tag nrho.

Lub tshuab ziab khaub ncaws ua kom huv ntawm cov kua mem pa yog ib qho kev sib cais ntawm ntau yam, suav nrog cov kua zaub, cov txheej txheem ib puag ncig, thiab luam ntawv thev naus laus zis. Los ntawm kev nkag siab cov tswv yim no thiab kev ua haujlwm kom ua kom tiav cov ntawv kom qhuav, nws muaj peev xwm ua kom tiav cov xim zoo nkauj thiab ua kom muaj zog. Raws li luam ntawv thev naus laus zis txuas ntxiv mus ntxiv, txuas ntxiv kev tswj hwm kom muaj kev ua kom tiav rau cov kev qhia kom qhuav thiab kev siv cov ntawv thov kev lag luam.
