Ink yog lub teeb - resistant rau discoloration thiab discoloration

Ink nyob rau hauv tshav ntuj, nws cov xim thiab brightness yuav txawv nyob rau hauv txawv degrees ntawm kev hloov, meej lub teeb tsis kam thiab tsis hloov lub suab ntawm tus number case yog tsis, nyob rau hauv lub hnub muaj zog, tag nrho cov xim number case yuav tsim ntau yam kev hloov.Muaj ob hom kev hloov pauv.

Fade: nyob rau hauv qhov kev txiav txim ntawm lub hnub ci ultraviolet rays, number case lub teeb kuj tsis zoo, poob lub qub ci xim, xim yuav daj ntseg grey.Tshwj xeeb tshaj yog lub teeb xim number case thiab plaub-xim teeb luam ntawv thaum daj thiab liab ob xim ploj sai dua, thiab cyan thiab number case ploj qeeb.

Discoloration: as opposed to printing number case dub discoloration, xim hloov nyob rau hauv qhov kev txiav txim ntawm lub hnub ci yog tsaus, xim kuj tau hloov, tib neeg hu qhov no hloov discoloration.

Cov nyhuv ntawm emulsification

Offsctdruckmasenten luam ntawv phaj tsis tuaj yeem sib cais los ntawm ntub ib feem ntawm lub phaj, offsctdruckmasenten yog thawj dej ntawm tus number case, dej yuav inevitably tshwm sim emulsifying phenomenon.Ink emulsion xim yuav attenuate, tab sis, tom qab evaporation ntawm dej tuaj yeem rov qab cov xim qub, yog li cov dej ntau dua, qhov ntau dua ntawm emulsion, yuav ua rau cov xim tsis zoo.Hauv particular, qhov degree ntawm emulsification ntawm cov xim sib txawv kiag li ua ke, qhov tshwm sim ntawm discoloration yog qhov tshwj xeeb tshaj yog.

Cov khoom siv ntawm daim ntawv nto smoothness

Daim ntawv nto smoothness thiab imprinting daim ntawv muaj kev sib raug zoo, tsis du daim ntawv feem ntau xav tau siab dua, thiaj li yuav ua rau tus number case thiab nws muaj kev sib cuag zoo.Xws li luam ntawv number case viscosity, liquidity, tswj ib tug npaum li cas ntawm number case zaj duab xis thickness, nce siab feem ntau ua rau molecularly imprinted kis cheeb tsam, tib lub sij hawm, daim ntawv dips nyob rau hauv qhov chaw, tab sis tseem tsis zoo tiv tauj, xws li: coated ntawv thiab ntawv xov xwm nyob rau hauv tib lub phaj luam ntawv imprinting teebmeem muaj qhov sib txawv loj dua, tuaj yeem pom tseeb qhov sib txawv ntawm cov ntawv luam tawm.

Absorbability ntawm ntawv

Daim ntawv, kuj yog qhov loj ntawm qhov nqus thiab cov nyhuv replication muaj kev sib raug zoo, feem ntau nyob rau hauv kev luam ntawv zoo ntawm cov ntaub ntawv yog xoob ntawm daim ntawv, yog number case liquidity, tsis tshua muaj viscosity, daim ntawv yuav nqus ntau tus number case txheej kev twb kev txuas, yog hais tias cov ntaub plaub stoma. txoj kab uas hla ntau dua li txoj kab uas hla ntawm cov xim pigment, ces, txawm tias cov pigments yog nqus tau, qhov saturation ntawm imprinting txo.Yuav tsum tau nce tus number case txheej thickness kom tsim nyog.Txawm li cas los xij, txhawm rau ua kom lub thickness ntawm tus number case txheej, thaum lub sij hawm embossing yuav ua rau "kis", cuam tshuam cov nyhuv ntawm imprinting daim ntawv.Absorbability ntawm daim ntawv me me, tuaj yeem ua rau feem ntau ntawm cov yeeb yaj kiab number case tshwm nyob rau saum npoo ntawm daim ntawv, kom cov imprinted number case txheej tau zoo saturation.

Daim ntawv permeability daim ntawv permeability yog loj, yuav ua rau cov number case txheej thickness nyias, daim ntawv nto pores loj, tab sis kuj ua ib feem ntawm cov pigment hais tau infiltrated rau hauv daim ntawv nyob rau tib lub sij hawm, yog li ntawd muaj kev nkag siab ntawm cov xim.Txog rau qhov kawg no, siv qhov ntxhib saum npoo, xoob kev ntxhib los mos ntawm daim ntawv, thiab tus cwj mem fluidity thiab daim ntawv loj, kom xyuam xim rau xim.

Pigment tsis resistant rau tshav kub

Ink nyob rau hauv cov txheej txheem ziab, lub teeb nrawm - ziab roj hmab luam ntawv number case yog feem ntau conjunctiva - oxidation ziab.Offset luam ntawv number case kom qhuav ua ntej muaj cov theem ruaj khov, tus number case oxidation polymerization yog exothermic cov tshuaj tiv thaiv, ziab sai heev yuav muab cov cua sov ntau, yog tias cov cua sov tso tawm maj mam, nws yuav tsis ua kom sov xim xim.Piv txwv li: kub xim number case darkens thiab poob nws thawj luster.

Thaum lub sij hawm luam ntawv, cov ntawv luam ntawv tau muab tso rau hauv pawg, vim tias stacked ntau dhau, qhov nruab nrab ntawm lub tshuab luam ntawv number case oxidation polymerization exothermic cov tshuaj tiv thaiv, tshav kub tsis yooj yim xa tawm, kub kub nyob rau hauv nruab nrab ntawm qhov ntau discoloration. .

Cov roj qhuav muaj lub teeb pom kev zoo

Xim number case belongs rau lub suab txias, lub teeb daj, emerald ntsuab, lub pas dej xiav thiab lwm yam xim xim, tsis txhob siv cov roj qhuav qhuav, vim cov roj dryness liab nws tus kheej nrog cov ntshav sib sib zog nqus, yuav cuam tshuam cov xim ntawm lub teeb number case.

Cov roj dawb qhuav zoo nkaus li dawb, tab sis lub conjunctiva yog xim av daj tom qab oxidation.Yog tias cov roj dawb qhuav ntau dhau lawm, cov ntawv luam tawm yuav daj-xim av thaum qhuav, thaum cov xim ntawm cov xim tsaus nti xws li ntsuab, dub thiab ntshav nrog cov roj qhuav qhuav yuav tsis cuam tshuam zoo heev.

Ink tsis yog alkali-resistant

Cov ntawv luam ntawv PH tus nqi = 7, cov ntawv nruab nrab yog qhov zoo tshaj plaws, cov xim tsis muaj kuab lom uas ua los ntawm cov kua qaub, alkaline tsis zoo, organic pigments acid, alkaline zoo dua, tshwj xeeb tshaj yog cov xim nruab nrab xiav, cov xim xiav tsaus yuav ploj nrog alkali.Alkali nruab nrab daj xim rau xim liab, electrochemical aluminium foil stamping, Is Nrias teb yuav dhau los ua cov xim daj thaum ub hauv cov tshuaj alkaline, tsis muaj gloss, tsis muaj zog alkaline ntawv ntau dua, feem ntau ntsib hauv kev luam ntawv khi tom qab tsim khoom muaj alkaline adhesives, yog tias ntim khoom kho kom zoo nkauj luam ntawv cov khoom yog alkaline khoom xws li xab npum, xab npum, ntxhua khaub ncaws thiab lwm yam, txhua tus xav xav txog cov alkali tsis kam, tsis kam rau saponification ntawm number case kev ua tau zoo.

Kev cuam tshuam ntawm qhov chaw cia khoom

Feem ntau cov khoom luam tawm rau lub sijhawm ntev cia, yuav inevitably qhia qhov tshwm sim ntawm daj, yog vim li cas rau ntau yam hauv qab no.

Daim ntawv fiber ntau muaj lignin thiab discoloration.Cov ntawv xov xwm luam tawm ntawm cov ntawv xov xwm feem ntau yuav tig daj thiab nkig.

Offset luam ntawv plaub-xim dot overprinter xim luam ntawv cov khoom, feem ntau nyob rau hauv tshav ntuj, huab cua, cua thiab los nag, sab nraum zoov kub erosion, thiab lwm yam, vim hais tias cov xim tsis yog lub teeb resistant, tshav kub resistant, thiab xim los yog ploj.

Cov yam ntxwv ntawm kev hloov xim ntawm cov ntawv luam tawm txawv thiab tsis muaj cov khoom uas tuaj yeem ua tau txhua yam.Ib yam li lub hnab ntim ntawv no, nws cov xim tuaj yeem hloov pauv raws sijhawm.Tab sis tsawg kawg nws zoo nkauj thaum peb siv nws.
