Ink thiab Material Compatibility

Raws li tau hais ua ntej, lub zog qis ntawm cov khoom siv tuaj yeem ua rau cov kua nplaum tsis zoo. Qhov tseeb, txhawm rau daws qhov teeb meem no, ntau tus neeg xa ntawv number case tau qhia cov inks tshwj xeeb tsim rau cov khoom siv hluav taws xob tsawg. Cov inks no tuaj yeem daws qhov teeb meem ntawm kev xaiv tus number case ntawm cov khoom siv hluav taws xob tsawg. Txawm li cas los xij, tsis muaj universal number case nyob hauv lub ntiaj teb. Yog tias tus neeg muab tus cwj mem xav tau muab cov kev daws teeb meem zoo sib xws, cov tuam txhab luam ntawv tuaj yeem xa cov ntaub ntawv mus rau cov neeg xa ntawv number case, leej twg yuav ua cov kev ntsuam xyuas los txiav txim siab seb cov inks uas twb muaj lawm tau haum rau cov ntaub ntawv thiab pom zoo kom tus number case tsim nyog tshaj plaws rau luam cov ntaub ntawv rau cov tuam txhab luam ntawv.

Txheej txheem teeb meem

Qee daim ntawv lo yuav tsum loj - cheeb tsam luam ntawv nrog ntau xim sib tshooj. Nyob rau hauv tas li ntawd, qhov kev txiav txim ntawm daim ntawv thov xim yog ib qho tseem ceeb tshwj xeeb. Tus kws sau ntawv ntseeg tias qhov tsim nyog ib ntus yog sau cov cheeb tsam me me ua ntej thiab loj dua tom qab, ntau npaum li qhov ua tau kom tus number case luam tawm rau ntawm cov khoom siv saum npoo es tsis yog rau lwm txheej ntawm tus number case. Qhov no yog vim feem ntau inks, tshwj xeeb tshaj yog UV inks, muaj cov khoom siv silicon. Tom qab luam ntawv thiab ziab, lawv tsim ib txheej ci ntsa iab, uas yog vim li cas qhov ci ntawm cov duab luam tawm feem ntau siab heev tom qab siv UV inks. Txawm li cas los xij, txheej ci ntsa iab no tsis zoo rau qhov adhesion ntawm lwm cov xim inks, uas txhais tau hais tias cov xim tom ntej uas luam tawm ntawm cov xim number case twb qhuav lawm ntau dua tev tawm.

Tsis tas li ntawd, qhov adhesion ntawm inks ntawm cov xim sib txawv ntawm qhov chaw ntawm tib cov khoom kuj yuav txawv. Tus sau tau ntsib cov xwm txheej zoo li no: rau tib hom khoom siv zaj duab xis thiab siv tib yam khoom siv rau ntawm - qhov chaw luam ntawv, xim liab thiab daj inks adhered zoo heev, thaum xiav number case muaj adhesion tsis zoo, tawm tag nrho thaum tev nrog daim kab xev tom qab luam ntawv. Yog vim li cas rau qhov teeb meem no, raws li kev txheeb xyuas los ntawm tus sau, yog qhov sib txawv ntawm cov inks ntawm cov xim sib txawv hauv kev sib raug zoo nrog cov khoom. Yog li ntawd, thaum lub tuam txhab luam ntawv ntsib qhov teeb meem no, nws tuaj yeem sim sim nrog inks los ntawm lwm hom.

Ntawm no, tus sau kuj xav taw tes rau lwm qhov teeb meem: UV inks muaj post- kho cov khoom. Thaum lub sij hawm luam ntawv daim ntawv lo, yog tias cov khoom luam tawm tshiab tau sim tam sim ntawd, tus number case adhesion yuav zoo li tsis zoo. Txawm li cas los xij, tom qab muab tso rau ob peb hnub thiab sim nrog daim kab xev dua, tus number case qhia tau tias muaj kev txhim kho tseem ceeb hauv adhesion, uas yog vim tus ncej - kho qhov xwm txheej ntawm UV number case. Raws li txoj cai, UV number case yuav tsum qhuav tam sim ntawd thaum raug ultraviolet teeb thiab yuav tsum tsis txhob muaj teeb meem tom qab- kho. Txawm li cas los xij, hauv kev tsim khoom tiag tiag, tsis tiav UV raug tshwm sim feem ntau tshwm sim, feem ntau vim tias ntau lub tuam txhab luam ntawv txuas ntxiv siv UV teeb dhau lawv lub neej kev pab cuam rau tus nqi (feem ntau, cov tuam txhab hloov lub teeb tsuas yog thaum tus number case tsis tuaj yeem qhuav tag).

Thaum lub teeb UV dhau ntawm nws lub neej kev pabcuam, nws lub zog maj mam poob qis thaum lub sijhawm kho, ua rau muaj qhov tshwm sim 'tsis tseeb qhuav'. Qhov no txhais tau hais tias tus number case zoo li qhuav ntawm qhov chaw, tab sis tus number case hauv qab yog tiag tiag tsis qhuav. Yog li ntawd, yog tias cov khoom raug kuaj tam sim tom qab luam ntawv, tus number case yuav muaj kev cuam tshuam loj heev. Tab sis tom qab tso tseg rau ib lub sij hawm, tus number case ntxiv dries tag nrho vim ib puag ncig yam, thiab adhesion yuav zoo heev thaum rov kuaj dua. Yog li, qee zaum yog tias ib pawg qhia pom tias tus number case adhesion tsis zoo, tsis txhob txiav txim siab tam sim ntawd los txiav nws; Nws yog qhov zoo dua los tso nws rau ob peb hnub thiab sim dua, vim tias qhov adhesion tuaj yeem txhim kho tau zoo. Tus sau tau siv txoj kev no los pab cov tuam txhab lag luam rov qab tau nyiaj txiag poob ntau.

Teeb meem xim txawv

Cov neeg ua haujlwm uas tau ua haujlwm hauv flexographic luam ntawv rau lub sijhawm ntev feem ntau ntsib cov teeb meem hauv qab no: nrog rau cov txheej txheem tib yam, cov khoom siv tib yam, thiab cov ntaub ntawv zaj duab xis muab los ntawm tib tus neeg muag khoom tab sis los ntawm cov khoom sib txawv, tuaj yeem pom cov xim sib txawv ntawm cov khoom luam tawm. Qhov teeb meem no yog qhov teeb meem tshwj xeeb rau cov neeg ua haujlwm kev tshaj lij: tsis muaj dab tsi tshwm sim tau hloov pauv, tab sis cov xim txawv txawv. Yuav daws qhov no li cas?

Qhov tseeb, txawm tias cov ntaub ntawv yog muab los ntawm tib tus neeg muag khoom, cov khoom sib txawv tuaj yeem muaj lub zog sib txawv. Yog li ntawd, thaum ntsib qhov teeb meem no, koj tuaj yeem xub siv lub iav tsom iav kom pom seb puas muaj cov kev hloov pauv pom tseeb hauv cov dot loj ntawm cov khoom luam tawm hauv cov khoom no piv rau yav dhau los batch. Yog tias qhov loj me me hloov pauv loj, yuav muaj qhov sib txawv xim loj dua. Qee zaum cov dot loj ntawm ntau xim hloov, thiab qee zaum tsuas yog ib qho xim dot loj hloov. Nyob rau hauv rooj plaub tom kawg, kuv ntseeg tias nws tsis muaj feem cuam tshuam nrog cov khoom siv thiab tej zaum yuav yog vim cov phaj laus thiab kev luam ntawv siab. Yog tias nws yog yav dhau los, ces nws yuav tsum tau txiav txim siab seb lub zog saum npoo ntawm ob pawg khoom sib txawv, ua rau tus number case shrinkage ntawm cov khoom.

Lub sijhawm no, yog tias muaj cov ntaub ntawv pov tseg los ntawm cov ntawv luam dhau los, koj tuaj yeem luam tawm raws li cov xwm txheej qub los txiav txim seb qhov sib txawv ntawm cov xim yog tshwm sim los ntawm cov khoom sib txawv ntawm cov khoom sib txawv. Yog tias tsis muaj cov khoom siv yav dhau los, koj tuaj yeem txiav txim siab siv kev kho mob corona hauv kab kom pom tias cov xim sib txawv zoo dua.
