Screen Printing Ink: Los ntawm pleev rau yav tom ntej kev txhim kho hauv daim ntawv thov
Jul 26, 2024
Screen luam ntawv number case yog ib hom number case tshwj xeeb uas siv rau kev tshuaj ntsuam luam ntawv, uas yog siv dav hauv kev luam ntawv ntawm textiles, ntawv, yas, iav, hlau thiab ntau yam substrates. Lub tshuab luam ntawv yog lub tshuab luam ntawv uas siv lub vijtsam hloov cov number case mus rau lub substrate, uas muaj qhov zoo ntawm cov kev pabcuam siab, cov xim ci thiab muaj zog. Hauv qab no yog cov ncauj lus kom ntxaws txog kev tshuaj ntsuam luam ntawv number case.
1. Ink muaj pes tsawg leeg
Screen luam ntawv number case yog tsim los ntawm cov xim, binders, kuab tshuaj thiab additives.
Pigments: Pigments muab cov xim ntawm tus number case thiab tuaj yeem ua cov organic lossis inorganic pigments. Organic pigments yog ci xim thiab haum rau textile thiab ntawv luam ntawv; inorganic pigments muaj kev tiv thaiv huab cua zoo dua thiab tiv thaiv tshav kub thiab haum rau qhov chaw sab nraum zoov thiab kub kub.
Binders: Binders yog cov yeeb yaj kiab tsim cov tshuaj ntawm tus number case, uas txiav txim siab qhov adhesion thiab durability ntawm number case ntawm substrate. Feem ntau siv binders muaj xws li hluavtaws cob, polyesters, polyurethanes, thiab lwm yam.
Cov kuab tshuaj: Cov kuab tshuaj yog siv los ua kom yaj thiab tawg cov xim thiab cov binders kom muab tus cwj mem kom fluidity. Cov kuab tshuaj muaj xws li cawv, ketones thiab esters, thiab lwm yam.
Additives: Additives yog siv los txhim kho cov khoom ntawm inks, xws li ziab ceev, rheology, thiab anti-stickiness. Piv txwv li, defoamers, antifreeze agents, plasticizers, thiab UV stabilizers.
2. Hom Ink
Nyob ntawm daim ntawv thov thiab substrate, tshuaj ntsuam luam ntawv inks tuaj yeem muab faib ua ntau hom:
Solvent-based Inks: Hom number case no siv cov kuab tshuaj organic ua cov khoom thauj, muaj qhov ziab sai thiab adhesion zoo, thiab haum rau cov khoom tsis nqus dej xws li plastics, hlau, thiab iav. Qhov tsis zoo yog tias thaum cov kuab tshuaj evaporates, nws tso cov pa phem, uas muaj qee yam cuam tshuam rau ib puag ncig thiab kev noj qab haus huv.
Dej-raws li Inks: Siv dej ua cov kuab tshuaj, nws yog ib puag ncig tus phooj ywg thiab haum rau textile thiab ntawv luam ntawv. Txawm hais tias cov dej-raws li inks qhuav maj mam, lawv cov ntxhiab tsw thiab tsawg VOC (volatile organic compound) emissions ua rau lawv nrov nyob rau hauv ib puag ncig cov ntaub ntawv.
UV-curable Inks: Hom number case no kho tau nyob rau hauv ultraviolet lub teeb, dries sai heev, haum rau ntau yam substrates, thiab muaj qhov zoo ntawm khawb tsis kam thiab tshuaj tiv thaiv. UV curing inks yog hnyav-dawb thiab ib puag ncig tus phooj ywg, tab sis yuav tsum tau tshwj xeeb UV kho cov cuab yeej.
Plastisol inks: Hom number case no tsuas yog siv rau kev luam ntawv textile, tshwj xeeb tshaj yog rau cov khaub ncaws xws li T-shirts. Nws kho ntawm qhov kub thiab txias los tsim cov qauv mos, ntxuav tau yooj yim. Cov khoom tseem ceeb ntawm plastisol inks yog polyvinyl chloride (PVC) thiab plasticizers.
3. Ink kev ua haujlwm
Kev ua tau zoo ntawm kev tshuaj ntsuam luam ntawv inks ncaj qha cuam tshuam rau kev luam ntawv zoo thiab cov txiaj ntsig ntawm cov khoom kawg. Nov yog qee qhov ntsuas kev ua haujlwm tseem ceeb:
Viscosity: Lub fluidity ntawm tus number case, uas cuam tshuam rau nws hloov thiab luam ntawv zoo ntawm qhov screen. Txoj cai viscosity tuaj yeem ua kom muaj kev sib faib ntawm tus cwj mem thiab cov ntsiab lus meej.
Adhesion: Lub peev xwm ntawm tus number case kom ua raws li lub substrate txiav txim siab qhov ntev ntawm cov ntawv luam tawm. Cov substrates sib txawv xav tau cov nplaum sib txawv kom ntseeg tau zoo adhesion.
Opacity: Lub peev xwm ntawm tus number case los npog lub hauv paus xim ntawm substrate. High-occluding inks tuaj yeem ua tiav cov xim ci ntawm cov substrates tsaus.
Durability: Nrog rau kev puas tsuaj, tshuaj tiv thaiv, huab cua tsis kam, thiab lwm yam. Cov ntawv luam ntawv muaj peev xwm ua kom ntseeg tau tias cov khoom luam tawm tseem nyob hauv qhov chaw zoo hauv ntau qhov chaw.
4. Daim ntawv thov teb
Screen luam ntawv number case yog dav siv nyob rau hauv ntau lub lag luam, suav nrog tab sis tsis txwv rau:
Textile printing: T-shirts, kaus mom, handbags thiab lwm yam khaub ncaws thiab accessories printing, feem ntau yog siv plastisol number case thiab dej-raws li number case.
Kev tshaj tawm thiab lub logo: Billboards, cov paib, cov ntawv tshaj tawm thiab lwm yam kev luam tawm sab nraum zoov thiab sab hauv tsev, feem ntau siv UV curing number case thiab kuab tshuaj raws li tus cwj pwm.
Cov ntawv thov kev lag luam: Logo thiab kho kom zoo nkauj luam ntawv ntawm cov khoom siv hluav taws xob hauv tsev, dashboards, automotive qhov chaw, thiab lwm yam, feem ntau siv cov kuab tshuaj raws li cov kuab tshuaj thiab UV curing inks.
Ntim Cov Ntawv Luam Ntawv: Cartons, hnab yas, iav fwj thiab lwm yam ntim cov ntaub ntawv luam ntawv, cov kuab tshuaj dej thiab cov kuab tshuaj raws li cov kuab tshuaj muaj ntau dua.
5. Kev txhim kho yav tom ntej
Nrog rau kev txhim kho ntawm kev tiv thaiv ib puag ncig thiab kev nce qib ntawm thev naus laus zis, tshuaj ntsuam luam ntawv number case yog tsim los ntawm kev tiv thaiv ib puag ncig thiab kev txawj ntse:
Ib puag ncig tus phooj ywg tus cwj pwm: Cov kua dej raws li tus cwj mem thiab UV kho tus cwj mem nrog VOC emissions qis yuav siv dav dua, thiab cov qauv tsis muaj tshuaj lom thiab degradable number case yuav raug tsim.
Ntse number case: Inks nrog cov lus teb ntse xws li kev hloov pauv kub thiab lub teeb hloov, xws li kub-hloov inks thiab lub teeb-hloov inks, yuav coj ntau cov ntawv thov tshiab rau kev tshuaj ntsuam luam ntawv.
