1. Cov dej ua rau menyuam yaus thiab pigment inks (nrog rau latex)
Qhov ntau cov phev nyob rau hauv kev ua lag luam niaj hnub no yeej ua tau zoo heev. Rau cov teeb meem loj hauv txhua hom phev, carcinogens xws li xee tes, uas feem ntau pom muaj nyob rau hauv daj pigments, tau raug tshem tawm ntau. Txhawm rau xyuas kom koj cov xim daj lossis pig-based daj phaus suav tsis muaj nickel, muaj cov ntaub ntawv Kev Nyab Xeeb Khoom Siv (MSDS) los ntawm cov neeg muag khoom uas tsim thiab muag cwj nyob hauv Tebchaws Meskas. Cov ntaub ntawv no feem ntau muaj nyob rau ntawm lub tshuab luam ntawv los yog number case manufacturer lub website, thiab tuaj yeem thov tau los ntawm lub chaw muag khoom.
Yog nickel raug siv rau hauv tus cwj pwm, nws yuav tsum tau muab teev rau hauv cov khoom Material Safety Data Sheet (MSDS) thiab ua daim ntawv ceeb toom rau carcinogen. Nws yog ib lub tswv yim zoo los tshawb xyuas cov Khoom Siv Kev Nyab Xeeb rau tus number case uas koj siv los pab koj paub tiv thaiv koj tus kheej, koj cov neeg ua hauj lwm thiab koj cov neeg muas zaub ntawm cov tshuaj yeeb dej caw. Yog tias "ntau cov khoom xyaw" (tshwj tsis yog lub tshuab fais fab) muaj npe nyob hauv Cov Khoom Siv Khoom Siv Kev Nyab Xeeb ntawm muab los ntawm tus neeg sab nrauv luam tawm, ces koj yuav tsum ceev faj. Vim tias lo lus no tuaj yeem siv los npog lub neej muaj teeb meem rau cov khoom xyaw. Qhov no muaj tseeb rau txhua hom phev, tsis yog dej nyob hauv qab. Cov ntawv luam tawm thiab cov cwj pwm pluaj feem ntau tsis zais los sis tsis tshua muaj txiaj ntsig ntawm kev muaj kev phom sij. Qhov no kuj yog kev txhawj xeeb txog kev hnyav hnyav - thiab cov tshuab luam ntawv UV-curable.
Cov kuab tshuaj rau cov xim muaj kuab zas thiab pigment-based inks yog cov dej feem ntau nrog qee cov neeg ua haujlwm, feem ntau yog glycol ethers, uas muaj kev nyab xeeb heev. Ib qho dej cawv thiab ib qho tshuaj feem ntau yog ntxiv rau cov phais no kom tsis pub muaj cov pwm los yog cov kab mob hauv cov kab mob, tab sis nws yuav txhaws cov pob tw.
Lub polymer txuam nrog pigment dispersion nyob rau hauv cov yas hauv qab yog feem ntau yog acrylic polymer uas tsis ua teeb meem loj. Nyob rau hauv cov yas qaum, lawv yog cov polymer uas yog agglomerate thiab tsim ib zaj duab xis thaum lub sijhawm evaporation ntawm dej thiab cov neeg pleev kob. Qhov no yog lub cev nqaij daim tawv tsis muaj tshuaj lom neeg. Lo lus "curing" yog siv qee cov tshuaj pleev xim, uas txhais tau hais tias nws yuav rhaub kom txog thaum muaj zaj duab xis thaum lub sijhawm tsim.
2, dej-based ntaub number case
Cov lej uas muab luam tau ncaj qha rau ntawm daim ntaub yuav tau pigmented lossis dyed. Pigment-type inks yog zoo li cov uas siv los ua cov yeeb yaj kiab los yog cov ntawv sau tawm, thiab muaj ib phau ntawv zoo li "latex" los txhim kho tus qauv ntawm tus cwj mem. Dye-type inks yog lwm cov ntaub ntawv. Nyob ntawm seb hom fibre ntau npaum li cas, tej zaum lawv yuav muaj sublimation dyes (me molecules of disperse dyes), disperse dye inks rau luam ntawv rau hluavtaws fibers, reactive dye inks rau printing ntawm cellulose fabrics xws li paj rwb, thiab kua qaub thev dej hauv Xav tau luam tawm rau ci ntaub lis luj thiab lo lo ntxhuav.
Sublimation dyes yuav tsum tau rhuab tom qab luam ntawv mus diffuse ua hluavtaws fibers (feem ntau polyester). Dyes uas tsis tag nrho rau hauv cov hlwv yuav tsum tau muab ntxuav tawm ntawm cov ntaub. Yog tsis muaj tshuaj lom neeg cov tshuaj nyob rau hauv txoj kev no, yog li tsis muaj teeb meem by-products. Txawm hais tias yog siv ntawv hloov lossis ncaj luam, cov ntaub ntawv siv los yeej tseem zoo tib yam. Undifusing dyes tuaj yeem ua rau txob mus rau ntawm daim tawv nqaij, yog li yog siv hauv tsoos tsho, ntxuav nws tawm ntaub yog qhov tseem ceeb heev. Yog tias cov duab yuav raug siv rau cov paib los yog kev tuaj yeem, tsis tas siv los ntxuav lawv.
Acid dyes thiab reactive dyes react nrog lub fibers thiab xa mus rau cov ntaub ntawv nyob rau hauv ib tug sib npaug reactive ncees, cia li zoo li luam ntawv rau cov ntaub favics. Ua ntej yuav kho thiab kho tom qab yuav tsum tau ua kom muaj kev sib tov tshuaj. Cov unreacted zas thiab ntawm cov khoom ntawm cov tshuaj tiv thaiv, nrog rau cov khoom siv pretreated, yuav tsum tau muab tshem tawm tom qab kev kho mob kom cov ntaub ntawv tsis nyob hauv daim ntaub. Hauv cov qauv analog luam ntawv, manufacturers feem ntau ntxuav dyes uas tsis haum txaus los yog tsis-diffusing tom qab luam ntawv kom tsis txhob ntxiv dye rau lawv cov wastewater. Qhov no yog vim li cas cov khaub ncaws uas koj yuav, tshwj xeeb tshaj yog cov polyester uas dyed, yuav tsum tau muab ntxuav kom nyias mus tshem tawm cov qaub ncaug undiffusing.
3, xaj kuab hnyav thiab hnyav hnyav
Cov phom sij hauv qhov ua tau thiab tsis muaj zog-yog qhov txawv txav ntawm aqueous inks. Hauv pigmented inks, lawv siv cov tshuaj solvents siv dej ua tus thawj number case cab kuj (txuas). Raws li kev teeb meem kev nyab xeeb, cov xim phom tooj liab thiab polymer molecules nyob rau hauv cov cwj mem yog zoo ib yam li cov neeg ntawm aqueous inks. Tiam sis, qhov hnyav yog lwm qhov teeb meem nkaus.
Ua ntej, qhov hnyav feem ntau yog qhov hnyav ntawm tus number case thiab lawv yog cov organic, uas txhais tau hais tias lawv yog cov nplaim taws thiab tej zaum kuj tawg thaum uas tov nrog huab cua (nyob ntawm qhov point flash ntawm tus number case). Cov kuab tshuaj no tuaj yeem muab cais tawm yog cov organic compounds tebchaw (VOCs), uas ua rau ua rau muaj kev qias neeg thaum uas tawm hauv qhov chaw. Yog hais tias tib neeg lub cev tsis paub ntau tshaj los yog tso tawm mus rau hauv ib cheeb tsam hauv cov kua, nws yuav ua rau tib neeg thiab ntses. Tshuaj lom.
Qee qhov "muaj zog" los yog "xaw" solvent inks (feem ntau yog siv rau cov ntawv xov xwm sau) muaj cov kuab tshuaj nrog cov ntsiab lus uas tsis tshua muaj qhov flash. Flash taw tes hais txog qhov twg uas muaj cov vapors uas muaj feem yuav tawg taus. Cov phom-raws li muaj cov xim zoo tshaj plaws rau yas, tab sis muaj kev txhawj xeeb txog kev nyab xeeb. Ib txhia tuaj yeem ua rau mob plab. Rov ua dua, xyuas cov ntaub ntawv Kev Nyab Xeeb Khoom Siv rau cov cwj mem tshwj xeeb uas koj tau xaiv. Tsis txhob tham nrog cov neeg muag khoom muag los yog thaub vim lawv feem ntau txo cov kev phom sij.
Weak solvent inks yog ib hom cwj pwm uas cov chemists siv zog txo cov teeb meem yam tsis tas tua cov lej ua tau zoo. Rau cov tsis muaj zog uas tsis muaj zog, chemists uas tsim cov qauv hauv plhaus xaiv cov kuab tshuaj nrog cov ntsiab lus flash tshaj, tab sis qhov no ua kom ziab nyuaj. Lawv kuj tau xaiv ib qho hnyav nrog ib tus ntxhiab tsw kom tsis txhob muaj cov tshuab khov kho, uas ua rau poob thiab ua kom muaj zog (piv rau hom hnyav).
Qee cov tshuab luam ntawv manufacturers yuav hais tau tias vim tsis muaj cov ntxhiab tsw siv cov tshuaj tsis muaj zog, tsis tas siv lub tshuab luam ntawv. Nco ntsoov tias txawm tias koj tsis hnov tsw, tus neeg luam ntawv tus neeg ua haujlwm tseem tseem yuav tsum tau hnyav thiab xaj aerosol (aerosol) uas ntub thaum sijhawm luam ntawv (cov tee me me yuav tshwm sim thaum luam ntawv).
Lwm qhov teeb meem yuav tsum tau xam nrog cov hnyav hauv thooj tshuaj yog tias qhov hnyav residual evaporates rau hauv cov huab cua thaum lub sij hawm ntawm qhuav los kov. Nyob ntawm seb hom tshuaj hnyav npaum li cas, yog cov duab yuav tsum siv sab hauv tsev, qhov no tuaj yeem ua rau ntxhiab thiab teeb meem kev noj qab haus huv. Cov kuab hnyav hnoos muaj qhov teeb meem loj tshaj plaws, tab sis tag nrho cov tshuaj hnoos muaj kuab muaj qhov cwj pwm no.
4, UV curing kua
UV cov phom leej hau yuav sib thooj. Lawv hnov qab hauv UV teeb thiab hnov mob yog tias kua kua txav rau ntawm koj cov tawv nqaij. Koj yuav tsum hnav cov iav, vim tias yog tus cwj mem nkag mus rau hauv koj lub qhov muag, koj yuav raug mob hnyav (tsis txhob hais qhov kev puas tsuaj uas qhov kev sib zog ua rau lub qhov muag yuav ua rau koj ob lub qhov muag).
Muaj tsis paub tseeb tias cov phev no muaj mob thiab muaj cov tshuaj phem uas tsim kev puas tsuaj yog tias tsis ua haujlwm zoo. Muaj ntau lub tshuab luam ntawv cov kws ua lag luam yog tam sim no tab tom ua kom tsawg-ntxaug UV dua. Qhov no yog qhov yuav txo los sis tshem tawm cov co-solvent ntxiv rau hauv cov ntawv numberulation thiab nws yuav qhuav tawm lub sij hawm hauv tus number case, li yuav tsis tshua tsw ntxhiab, oligomers lossis photoinitiators.
Tom qab tus cwj mem muab luam tawm rau hauv substrate, UV teeb lub teeb pib pib hla cov oligomers thiab monomers hauv tus cwj pwm, tam sim ntawd tam sim ntawd yuav yog ib qho duab uas muaj peb sab thiab yuav tsum tau tsim ib txoj kev sib raug ntawm cov tshuaj / kev sib raug zoo nrog cov ntawv luam tawm substrate. Kev sib koom tes. Yog tias tsis kho tag nrho, cov khoom xyaw uas tsis zoo no yuav nyob twj ywm hauv cov ntawv. Rau qee cov ntaub ntawv, qhov no yuav tsis muaj teeb meem, tab sis yog tias cov ntaub ntawv kho tau zoo los ntawm kev sib txuas nrog cov neeg los yog siv hauv tsev, qhov no ua tau teeb meem.
Ntau lub UV printers thiab number case manufacturers hais tias lawv cov inks muaj peev xwm ua tau tag nrho reacted yam tsis muaj kev raug mob yog tias siv kom zoo. Hnov cov ntawv luam! Yog tias koj tuaj yeem hnov qab tus cwj mem, nws muaj tshuaj lom neeg tsis haum xeeb. Cov ntaub ntawv no muaj peev xwm yuav muab tau los ntawm cov substrate thiab tej zaum yuav muab tau los ntawm cov organic solvents uas tau ntxiv rau cov nyiaj me me rau ntawm cov ntawv numberulation los kho qhov kev ua tau zoo ntawm cov printhead, los yog los ntawm cov khoom tsis muaj teeb meem. Nyob rau hauv ob qho tib si, koj yuav tsum paub txog nws cov kev phom sij thiab siv lawv kom tsim nyog. Tsis txhob hnov qab xyuas cov Khoom Siv Kev Nyab Xeeb Khoom Siv thiab khaws cov kev tiv thaiv kom zoo.
Txhua yam, peb tau ua tiav zoo hauv kev tsim cov inkjet luam ntawv hauv qab thiab cov tshuab luam ntawv, tabsis tseem nco ntsoov nyeem cov ntaub ntawv kev ruaj ntseg ntawm cov ntaub ntawv rau tus cwj pwm, nkag siab txog kev tsim kev puas tsuaj, thiab ua tiag ceev faj kom txhob raug mob koj tus kheej thiab kev khiav hauj lwm. Cov neeg ua haujlwm, cov neeg muas zaub thiab chaw nyob.
