Cia peb 'pom qhov sib txawv' ua ke! Cov 'plaub qhov loj' no pab koj nkag siab qhov zoo sib xws thiab qhov sib txawv ntawm toner thiab inkjet technologies!

Kev sib piv thiab kev soj ntsuam ntawm ntau yam luam ntawv ConsumablesKev yooj yim, kev ntsuam xyuas hauv qab no yuav tsom rau plaub yam: lawv cov kev sib cuam tshuam nrog cov ntawv sau substrates, cov tsos ntawm cov khoom luam tawm, durability, thiab sustainability.Interaction nrog Label SubstratesWhen ntsuam xyuas cov kev sib cuam tshuam ntawm toner thiab inkjet inks nrog txawv substrates, weesion thiab pigmentation. Adhesion txiav txim seb puas thiab yuav ua li cas cov duab luam tawm yog tsau rau ntawm lub substrate, thaum pigment penetration qhia seb cov xim nyob rau hauv toner los yog number case infiltrates lub substrate. Hauv kev ntsuam xyuas, qhov siab tshaj plaws number case adhesion yuav tsum tau nrhiav thaum pigment penetration yuav tsum tsawg. Cov laj thawj tseem ceeb yog: (1) xim nkag mus rau qhov tsis zoo ntawm cov xim tob, dot duab, thiab dot loj; (2) Kev nkag mus rau xim ua rau siv tsis zoo ntawm cov xim, txhais tau tias ntau tus number case lossis toner yuav tsum ua kom tiav cov xim tib yam. Nyob rau hauv qhuav thiab kua toners, pigment molecules yog encapsulated nyob rau hauv siab polymer resins, thiab cov pigment hais yog loj dhau mus rau hauv lub fibers ntawm uncoated daim ntawv, thiab txawm tsawg dua mus rau coated ntawv fibers. Txawm li cas los xij, polyethylene resin nyob rau hauv cov kua toner (electronic number case) tsis sib haum nrog cov ntawv lossis cov ntawv txheej, thiab vim tias cov cab kuj ua kua yaj hauv cov resin tseem xav tau evaporate, qhov adhesion ntawm kua toner (electronic number case) cuam tshuam me ntsis. Yog li ntawd, piv nrog cov toner qhuav, kua toner (electronic number case) xav tau ib txheej, tsis yog los tiv thaiv cov xim nkag, tab sis los txhim kho adhesion. Qhov tseem ceeb, siv cov txheej txheej ntawm cov ntawv ntuj rau cov kua toner (electronic number case) kom ntseeg tau tias txawm tias adhesion tseem yog ib qho kev sib tw tseem ceeb.Txawm li cas los xij, kom ntseeg tau tias inkjet zoo, inkjet inks yuav tsum muaj viscosity tsawg, feem ntau tuav lub taub hau kub ntawm 45℃kom tsis txhob muaj viscosity tsawg (feem ntau 4-17 mPa·s). UV inkjet inks muaj viscosity txog rau lub sij hawm qis dua li feem ntau siv UV flexo inks, ua rau lawv muaj feem ntau nkag mus rau cov ntawv fibers. Qhov no yog vim li cas inkjet luam ntawv yuav tsum tau txheej txheej los tiv thaiv pigment penetration.Hais rau adhesion, dej-raws li inks feem ntau tsis xav tau txheej vim hais tias cov khoom encapsulating cov pigments yog ntau chemically sib xws nrog ntawv los yog ntawv coatings. Txawm li cas los xij, txhawm rau tiv thaiv pigment nkag mus thiab qhov nce ntxiv, cov txheej txheem tseem yuav xav tau. Rau UV inkjet luam ntawv, tag nrho cov number case txheej yuav tsum nyob twj ywm rau ntawm lub substrate nto kom tiav kev kho, thiab txhua tus number case uas nkag mus rau hauv lub substrate tsis tuaj yeem raug UV lub teeb kom txaus, ua rau kev kho tsis zoo. Kev muab cov khoom luam tawm nrog cov tshuaj tsis raug kho yog cumbersome rau cov tuam txhab luam ntawv thiab yuav ua rau muaj teeb meem ntau. Yog li ntawd, thaum luam tawm ntawm cov ntawv ntxeem tau, txheej txheej yuav tsum tau siv los xyuas kom muaj peev xwm kho kom zoo thiab ua kom zoo. Txawm li cas los xij, rau cov kua toner (electronic number case), adhesion yog me ntsis cuam tshuam vim cov cab kuj ua kua yaj hauv cov resin tseem xav tau evaporate, yog li cov kua toner (electronic number case) luam ntawv yuav tsum muaj txheej txheej. Qhov siab dua lub zog ntawm lub substrate piv rau tus number case lub zog saum npoo, qhov zoo dua qhov ntub dej. Zoo wettability yog qhov tseem ceeb rau kev ua kom muaj zog adhesion. Synthetic substrates feem ntau muaj lub zog qis dua, yog li rau qee qhov kev sib txuas ntawm cov substrates thiab inks, txheej txheej lossis corona kho yog xav tau los ua kom lub substrate lub zog saum npoo thiab txhim kho adhesion, txawm hais tias qhov no yuav cuam tshuam rau gloss uniformity thiab duab zoo.Vim cov hluavtaws substrates yog waterproof, dej -raws li inks nyob rau hauv substrate nto tom qab evaporation. Qhov no tuaj yeem ua tiav ob txoj hauv kev: siv cov inks uas muaj cov polymers los ua cov yeeb yaj kiab polymer tom qab dej evaporation, muab cov adhesion zoo, los yog siv cov txheej txheem polymer sib xyaw nrog cov xim xim.Cov kev sib cuam tshuam ntawm cov toner qhuav, kua toner, UV inkjet, thiab dej-raws li inkjet nrog daim ntawv lo thiab cov khoom siv hluavtaws yog piv rau hauv Table 1.

Pom Kev Pom Zoo Nyob ntawm cov ntawv luam tawm sib txawv, kev ua haujlwm lossis kev xav zoo nkauj tuaj yeem ua tus thawj. Cov kev sib tham hauv qab no tsuas yog txwv rau cov duab zoo, glossiness, tactile xav, thiab opacity.(1) Duab QualityImage zoo yog ib lub tswv yim nyuaj, thiab piav qhia txog txhua yam yog lub sij hawm-siv. Los ntawm qhov kev xav ntawm qhov tseeb qhov kev tso kawm thiab dot loj tswj, qhuav toner thiab ntub toner (electronic ink) luam ntawv tuaj yeem tsim cov duab ntau ntxiv ntawm tib yam (thawj) daws teeb meem piv rau UV inkjet thiab aqueous inkjet, thiab cov txheej txheem luam ntawv zoo ib yam thiab tswj tau ntau dua. (satin / silk matte). UV inkjet inks muaj viscosity tsawg, uas tso cai rau tus number case rau tus kheej -theem, tsim ib tug heev du nto nrog siab gloss. Ntawm qhov tod tes, aqueous inkjet, txawm tias muaj lossis tsis muaj primer, yuav muaj qib gloss sib npaug ntawm cov substrate vim tias tus naj npawb ntawm cov number case seem ntawm lub substrate nto tsis txaus cuam tshuam rau gloss. Cov duab txheej tsim los ntawm UV inkjet muaj qhov nruab nrab tuab ntawm li 6 μm, tso cai rau kev hais lus zoo nkauj. Qhuav toner tsim cov duab txheej nrog qhov nruab nrab tuab ntawm li 4 μm (cov xim xim dawb feem ntau yog thicker); Txawm hais tias nyias dua li UV inkjet txheej, nws yog txaus los tsim qee qhov kev ntxhib los mos 3D. Cov toner ntub dej (electronic number case) thiab aqueous inkjet tsim cov duab cov khaubncaws sab nraud povtseg uas nyias dhau los ua ib qho 3D textural effect. Rau cov dawb, ntau dua opacity zoo dua. Qhuav toner sib txuas cov xim ntau tshaj plaws nrog cov xim loj tshaj plaws ntawm cov xim, yog li qhov opacity ntawm dawb hauv One Pass luam ntawv feem ntau yog siab dua li ntawm cov xim dawb hauv flexographic luam ntawv. Cov xim me me hauv cov toner ntub dej zoo ib yam li cov toner qhuav, tab sis nws cov concentration qis dua (cov kua ua kua txo cov concentration), uas ua rau qis dua opacity. Tau kawg, nyob ntawm cov qauv siv tshuab, cov tshuab luam ntawv ntub dej (cov ntawv xov tooj hluav taws xob) tuaj yeem siv ntau txheej ntawm cov toner kom ua tau zoo dua opacity, tab sis qhov no txo ​​qis kev luam ntawv, txo cov khoom tsim tau, thiab ua rau cov nqi ntau lawm vim cov nqi kev pabcuam ntxiv rau ntau lub toner khaubncaws sab nraud povtseg.Rau UV inks siv nyob rau hauv One Pass high-ceev inkjet, cov pigment particles loj yuav tsum tsis txhob muaj me me clogging. xav tau los ntawm lub nozzle txwv qhov siab tshaj plaws pigment tus nqi, ua rau tsis tshua muaj opacity. Lub viscosity ntawm aqueous inkjet inks yog qis dua li ntawm UV inks, yog li ib qho - txheej xim dawb ink opacity nyob rau hauv aqueous inkjet kuj tseem qis.In sib piv, rau cov xim uas tsis yog xim dawb, opacity yuav tsum tsawg. Qhov me me ntawm cov xim pigment thiab qhov qis ntawm cov ntsiab lus pigment, qhov ntau pob tshab xim. Transparency kuj tuaj yeem ua kom zoo raws li cov duab txheej tuab, nrog cov txheej nyias nyias ua tau zoo dua.Qhov kev sib piv ntawm qhov pom kev pom ntawm cov toner qhuav, ntub toner, UV inkjet, thiab aqueous inkjet prints yog qhia hauv Table 2.

Huab cua tsis kam ntawm cov ntaub ntawv luam tawm Qhov zoo tshaj plaws, cov xim ntawm cov ntawv yuav tsum nyob ntev li ntev tau ntawm cov txee thiab thaum siv. Yog li, raws li kev npaj siv, cov ntaub ntawv luam tawm yuav tsum muaj peev xwm tiv taus khawb thiab khawb, kub, dej, thiab tshuaj lom neeg corrosion. Qhov tuab ntawm cov duab txheej, qhov qis dua qhov khawb kuj. Nyob ntawm qhov tuab ntawm cov duab txheej, yog tias qhuav toner thiab UV inkjet number case yuav tsum ua tib yam, cov toner qhuav thiab ntub toner (electronic number case) cov duab cov khaubncaws sab nraud povtseg yooj yim dua vim tias lub zog saum npoo ntawm UV inkjet number case yog qis dua li ntawm qhuav thiab ntub toner. Nyob rau hauv rooj plaub no, siv cov kua roj vanish UV rau saum lub toner- cov ntaub ntawv luam tawm tuaj yeem ua rau lawv zoo ib yam li UV inkjet prints. Dej-raws li inkjet prints qhia qhov zoo tshaj plaws khawb tsis kam; Txawm li cas los xij, txij li lawv cov duab cov khaubncaws sab nraud povtseg yog nyias heev, qhov khawb tsis kam ntawm lub hauv paus substrate kuj muaj qee yam cuam tshuam rau qhov kawg luam tawm. Thermal lamination tuaj yeem kho qhov teeb meem no. Ob lub UV inkjet thiab dej-raws li ink inks yog tshav kub{14}} tiv taus, nrog UV inkjet number case tsim kom kho cov polymers nrog cov ntsiab lus melting siab, thaum dej-raws li inks, vim tsis tshua muaj siab ntawm polymers ntawm lub substrate nto, yuav tsis yaj los yog nplaum thaum raug tshav kub.(3) Dej Resistance toner lossis UV inkjet inks tsis muaj tshuaj lom neeg rau dej, yog li lawv muaj dej tsis kam. Rau cov toner ntub dej (electronic number case), txij li cov dej{19}}raws li primer feem ntau yog siv rau hauv kev luam ntawv thiab cov primers tsis yog dej-resistant, nws yuav tev tawm. Ua kom dej-raws li inkjet daim ntawv lo tsis muaj dej, ib qho primer uas txo los yog inhibits hydrophilicity ntawm cov xim, xws li primer uas muaj calcium ntsev, yuav tsum tau siv.(4) Chemical ResistanceCrosslinking feem ntau muab cov tshuaj muaj zog, uas piav qhia vim li cas UV inkjet inks muaj zog tshuaj tiv thaiv piv rau cov toner, feem ntau ntawm cov tshuaj tsis zoo. crosslinked. Kev siv tshuaj lom neeg- tiv thaiv overlaminates tuaj yeem kho qhov teeb meem no. Cov tshuaj tiv thaiv ntawm cov dej-raws li inks yog vim tsis muaj cov khoom hauv cov number case uas muaj affinity rau cov tshuaj solvents.A kev sib piv ntawm huab cua tsis kam ntawm qhuav toner, ntub toner, UV inkjet, thiab dej-raws li inkjet luam ntawv cov ntaub ntawv yog qhia nyob rau hauv Table 3.

Sustainability ntawm Printed Products Zoo li lwm yam kev lag luam, kev lag luam luam ntawv kuj ntsib ib puag ncig kev nyuaj siab rau kev txhim kho kom ruaj khov. Yuav ua li cas cov tshuab luam ntawv sib txawv ua tau raws li kev tsim cov tshuaj khib nyiab, cov neeg siv khoom yooj yim, thiab kev ua raws li cov zaub mov? Ntawm no yog cov ncauj lus kom ntxaws tsom xam.(1) Tshuaj WasteDry toner electrostatic imaging printing thiab dej-raws li inkjet luam ntawv qhia ib qho feature: lawv tsis tsim cov tshuaj lom neeg pov tseg. Nyob rau hauv sib piv, UV inkjet luam ntawv, vim yog tus number case residue nyob rau hauv nws cov cartridges thiab siv cov tshuaj ntxuav thaum lub sij hawm luam ntawv, yuav tsum tau xyuam xim ua raws li cov lus qhia ntawm kev ruaj ntseg cov ntaub ntawv. Raws li kev ntub dej toner (electronic ink) luam ntawv, feem ntau ntawm cov cab kuj ua kua yog sau rau hauv lub tshuab luam ntawv thaum luam ntawv thiab kho raws li cov tshuaj khib nyiab, thaum qee qhov evaporates rau hauv qhov chaw tsim khoom, thiab qee qhov tseem nyob hauv cov ntaub ntawv luam tawm, nws thiaj li evaporating los ntawm cov khoom.(2) Tus neeg teb xov tooj yooj yim Ozone yog ib yam khoom muaj txiaj ntsig zoo, tab sis nws cov concentration yog qis dua qhov kev nyab xeeb. Cov khoom siv ozone lim kom zoo tuaj yeem txo cov ntxhiab tsw lossis cov khoom tsis zoo, xws li cov khoom tsim hauv ozone lim hauv Xeikon CX series cov cuab yeej, uas tuaj yeem tshem tawm cov teeb meem tsis zoo thiab tsw, ua rau cov txheej txheem luam ntawv tsis muaj ntxhiab tsw. Tsis tas li ntawd, thaum lub sij hawm UV inkjet luam ntawv ua haujlwm, cov neeg ua haujlwm yuav tsum ua kom muaj kev tiv thaiv los ntawm UV teeb pom kev.Hais txog volatile organic compounds (VOCs), cov toner ntub dej (electronic number case) electrostatic printing generates VOCs li cov cab kuj ua kua evaporates. Dej-raws li inkjet inks muaj humectants, qee qhov yog VOCs. Qhuav toner, tsis muaj additives, tsis tshua tsim VOCs.Qhov kev sib piv ntawm cov toner qhuav, ntub toner, UV inkjet, thiab dej{17}}raws li inkjet luam ntawv cov khoom yog qhia nyob rau hauv Table 4.
