Tuag txiav yog ib feem tseem ceeb ntawmself-adhesive daim ntawv lo ntau lawm. Nyob rau hauv cov txheej txheem tuag-txiav cov ntawv nplaum rau tus kheej, peb feem ntau ntsib qee qhov teeb meem, uas yuav ua rau muaj kev txo qis hauv kev tsim khoom, thiab tej zaum yuav ua rau cov khoom seem ntawm tag nrho cov khoom, ua rau poob zoo rau lub tuam txhab.
1. Ink drops ntawm ntug ntawm daim ntawv lo tom qab txiav tuag: Qee cov ntawv sau tau tsim los los ntshav tuag-txiav, uas yog, txiav tuag qhov twg muaj cov qauv luam tawm, uas yuav tsum muaj rab riam tuag txiav qhov twg. yog ink printing. Nyob rau hauv cov ntaub ntawv no, nws yog feem ntau ntsib hais tias tom qab daim ntawv lo tuag-txiav, tus number case ntog tawm qhov twg daim ntawv txiav. Yog tias nws yog cov khoom siv zaj duab xis-coated rau los ntshav tuag-txiav, zaj duab xis thiab number case yuav poob ua ke. Kev txheeb xyuas cov laj thawj, feem ntau yog ob yam uas ua rau muaj qhov tshwm sim no.
Ib qho yog vim qhov adhesion ntawm qhov chawcov ntaub ntawv luam tawm , tseem hu ua lub zog saum npoo ntawm cov khoom siv luam ntawv. Feem ntau hais lus, txhawm rau ua kom tus number case ua raws li cov khoom siv, lub zog saum npoo yuav tsum tsis txhob qis dua 38 dynes. Yog hais tias tus number case adhesion zoo yuav tsum tau, lub zog saum npoo ntawm cov khoom xav tau tsawg kawg yog 42 dyne lossis ntau dua, txwv tsis pub, yuav muaj teeb meem ntawm tus number case poob.
Qhov thib ob yog tias tus number case adhesion tsis txaus. Qee cov inks muaj teeb meem zoo lossis tsis sib xws nrog cov ntaub ntawv luam ntawv, uas tuaj yeem ua rau tsis muaj zog adhesion ntawm tus number case tom qab luam ntawv. Nyob rau hauv rooj plaub no, tom qab daim ntawv lo luam tawm thiab tom qab ntawd tuag-txiav, tus number case yog feem ntau yuav poob tawm ntawm ntug ntawm qhov tuag-txiav. Yog li ntawd, nws raug pom zoo tias lub tuam txhab luam ntawv ua daim kab xev ntsuas ntawm cov qauv luam tawm thaum nws nyob hauv lub tshuab, thiab yog tias qhov ntsuas tau ua tau raws li tus qauv, nws yuav raug tsim tawm ntau. Yog tias koj ntsib tus number case adhesion tsis txaus, koj tuaj yeem hloov tus number case los daws nws.
2. Glassine cov ntaub ntawv thaub qab yog txiav thiab curled: Muaj ob txoj hauv kev tau txaisself-adhesive daim ntawv lo : yob ntim thiab ntawv ntim. Ntawm lawv, daim ntawv ntim yuav tsum txiav cov khoom siv tus kheej nplaum. Feem ntau hais lus, cov khoom siv tus kheej nplaum siv rau cov ntawv ntim ntawv muaj cov ntawv tuab dua, thiab nws qhov hnyav feem ntau siab dua 95g / m2, tab sis qee zaum nws yuav tsum tau txiav cov ntawv nyias nyias nyias rau hauv cov ntawv. Qhov no yuav ntsib teeb meem ntawm curling ntawm cov khoom tau txais.
Qhov laj thawj tseem ceeb ntawm cov khoom siv iav rov qab rau curl tom qab txiav yog: cov dej noo ntawm daim ntawv rov qab yuav hloov pauv ntau heev vim muaj kev cuam tshuam ntawm ib puag ncig, thiab kev hloov pauv ntawm cov dej noo ntawm daim ntawv rov qab yuav ua rau daim ntawv me me los yog nthuav dav. ua nruj ua tsiv. Txij li cov khoom siv tus kheej nplaum yog cov khoom siv sib xyaw, qhov shrinkage ntawm daim ntawv rov qab thiab cov khoom siv saum npoo yog sib txawv, thiab qhov deformation tus nqi ntawm daim ntawv thaub qab thiab cov khoom siv saum npoo yuav txawv raws li cov av noo hloov nyob rau hauv tib qhov chaw. . Yog tias qhov deformation ntawm daim ntawv rov qab yog tsawg dua li ntawm cov khoom siv lub ntsej muag, cov khoom siv iav backing yuav curl upwards, txwv tsis pub, nws yuav curl downwards.
Thaum cov teeb meem zoo li no tau ntsib, nws yog ib qho tsim nyog yuav tsum tswj cov av noo ntawm lub rhiav kev tsim khoom kom ntau li ntau tau, kom cov av noo ntawm qhov chaw tsim khoom raug tswj los ntawm 50% thiab 60%. Xws li cov av noo yog qhov nruab nrab, thiab cov khoom deformation yuav tsis hnyav heev. Yog tias cov khoom tau raug deformed, ib qho yooj yim baffle tuaj yeem muab tso rau ntawm daim ntawv tso tawm txoj hauj lwm ntawm lub tshuab txiav tuag tau txais lub rooj los tsa cov ntawv tso tawm txoj haujlwm kom cov ntaub ntawv tuaj yeem khaws tau ib txwm thiab tom qab ntawd txheeb.
