Cov xwm txheej txhim kho thiab cov kev kwv yees ntawm kev lag luam ntu ntawm kev lag luam number case

1. Txheej txheem cej luam thiab kev faib tawm ntawm kev lag luam number case

Cov ntim yog cov khoom sib xyaw nrog cov xim tuaj yeem tsim cov sib cais ntawm cov ntawv thiab muaj cov viscosity. Nws yog qhov khoom siv tsis tseem ceeb hauv kev luam ntawv. Niaj hnub no hu rau kev txhim kho ntawm cov roj carbon tsawg kev lag luam thiab kev txhawb nqa kev tiv thaiv ib puag ncig ntsuab, kev tsim khoom thiab kev siv hluav taws xob txuag thiab kev tiv thaiv ib puag ncig hauv cov lag luam tau nce los ua kev pom zoo ntawm kev lag luam number case thiab luam ntawv kev lag luam.

Cov kab ntawv yog feem ntau ua los ntawm ntau yam resins thiab kuab tshuaj. Nws yog siv los ua cov xim tso tawm los kho cov viscosity, fluidity, dryness thiab hloov kev ua haujlwm ntawm tus number case, thiab ua kom tus number case qhuav, kho thiab tsim ib zaj duab xis nyob rau saum npoo ntawm cov substrate. Cov xim xaj txiav txim xyuas cov xim, tinting lub zog, chromaticity, hnyav tiv thaiv, lub teeb tiv thaiv, thiab kub tiv thaiv ntawm tus number case. Tus neeg sawv cev yog tus nqi me me ntawm cov khoom siv pabcuam ntxiv los txhim kho kev ua haujlwm ntawm tus number case thiab hloov kho kom haum rau kev luam ntawv ntawm tus number case thaum lub sijhawm tsim cov kua luam ntawv thiab cov txheej txheem luam ntawv. Muaj ntau yam ntawm inks, thiab ntau hom ntawm inks sib txawv ntau nyob rau hauv muaj pes tsawg leeg thiab ua tau zoo. Raws li cov ntawv luam ntawv sib txawv, cov hom kuab thiab hom kev nqus, nws tuaj yeem faib ua cov ntawv hauv qab no:

Kev faib tawm los ntawm kev luam ntawv hom: gravure number case, flexo number case, tshuaj ntsuam luam ntawv number case thiab dav hlau luam ntawv number case, thiab lwm yam.;

Qhia raws hom kuab: benzophenone-based solvent number case, roj-siv kua mem, dej cawv / ester kuab tshuaj pleev xim, dej-raws cov kua nyeem thiab cov kuab tshuaj dawb;

Txwv dej los ntawm txoj kev kom qhuav: hom ua kua qhuav tsis huv, oxidized conjunctival drying number case, thermal curing drying number case, ultraviolet tua (UV) kom qhuav tus cwj mem qhuav thiab lwm yam kom qhuav.

Cov lag luam number case tau yug tom qab thawj qhov kev lag luam tsim hauv thaj tsam sab hnub poob thiab tsim kho sai heev vim kev lag luam chemical thiab ntim luam tawm kev lag luam. Txij li thaum xyoo 1980, nrog txoj kev loj hlob ntawm kev lag luam thoob ntiaj teb thiab kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, qhov tsim tawm ntawm lub ntiaj teb kev tsim tawm kev lag luam tau txuas ntxiv, thiab kev lag luam tsom tau nce siab. Lub ntiaj teb saum 10 lub tuam txhab ua lag luam muaj nyiaj ntau dua 70% ntawm lub ntiaj teb feem lag luam. Tebchaws Asmeskas, Tuam Tshoj, Nyij Pooj thiab Yelemes tau dhau los ua lub ntiaj teb cov lag luam ua kua muag khoom thiab cov neeg siv khoom zoo. Xyoo tsis ntev los no, lub ntiaj teb cov zis txhua xyoo ntawm cov kua mem muaj li ntawm 4.2 txog 4.5 lab tons, ntawm uas kuv lub teb chaws cov kua mem tawm tso tawm txog li 17% ntawm lub ntiaj teb tag nrho cov kua mem tawm. Kuv lub teb chaws tau dhau los ua chaw tsim tshuaj number case ntau tshaj plaws thib ob hauv ntiaj teb.

2. Kev faib lag luam thiab kev sib piv ntawm kev lag luam number case

Kev tsim tawm txhua xyoo ntawm tus number case hauv kuv lub teb chaws tau nce los ntawm 697,000 tons hauv 2015 txog 794,000 tons hauv xyoo 2019, nrog tus nqi nruab nrab txhua xyoo tau nce txog 3.3%. Nyob rau kaum xyoo dhau los, qhov zoo thiab ntau ntawm kuv lub teb chaws cov khoom lag luam tau dhau los muaj kev hloov pauv ntau, tab sis kuv lub teb chaws txoj kev haus luam yeeb ib yam tseem tsawg heev. Nrog kev txhim kho txuas ntxiv ntawm kuv lub teb chaws kev lag luam hauv lub teb chaws, kev tsim kho tsis muaj zog ntawm kev siv cwj mem kuj tseem pom tseeb. Nyob rau hauv lub neej yav tom ntej, txoj kev loj hlob ntawm kuv lub teb chaws number case kev lag luam yuav tsis tsuas yog nce cov khoom lag luam, tab sis kuj tau them nyiaj ntau dua rau cov qauv kev hloov kho cov khoom lag luam, feem ntau yog ua kom cov khoom siv ntau lawm, nce kev tshawb fawb thiab kev txhim kho, txhim kho kev tshawb fawb thiab thev naus laus zis, cov khoom lag luam zoo thiab cov khoom lag luam, thiab ua kom nws zoo yoog raws li niaj hnub no kev lag luam luam ntawv yuav tsum muaj multicolor, kev kub ceev, kom qhuav sai, muaj kuab paug rau-dawb thiab qis noj.
Los ntawm qhov pom ntawm cov qauv khoom, raws li cov txheeb cais muaj feem xyuam xws li Tuam Tshoj Ink Association thiab Cov Hluav Taws Xob Kev Kho Mob Pawg Neeg ntawm Tuam Tsev Zej Zog Kev Yees Duab, cov khoom tsim tawm ntawm offset luam ntawv inks nyob hauv kuv lub teb chaws xyoo 2018 suav txog thaj tsam li 36.0% ntawm tag nrho cov tshuaj pleev ib ce. tsim tawm. Tag nrho cov khoom ntawm flexographic thiab gravure inks (kua inks yog qhov tseem ceeb Cov chaw thov ntawm lub tuam txhab tau kwv yees li 42.8% ntawm tag nrho cov kev lag luam nyob hauv tus naj npawb, thiab UV inks suav txog 9.2% ntawm tag nrho cov kua dej nyob hauv.

(1) UV number case kev lag luam tsom

Tam sim no, daim teb thov tseem ceeb ntawm kev tsim kua roj UV UV yog luam ntawv qib siab luam yeeb, cawv, khoom lag luam kho mob thiab ntim tshuaj pleev ib ce, uas suav tus nqi ntau dua ib nrab; tom ntej no yog kev luam ntawm ntau cov cim lag luam, cov ntawv them nyiaj, thiab lwm yam; tus so yog qee cov ntaub ntawv tshwj xeeb lossis cov hom phiaj tshwj xeeb Cov khoom lag luam, xws li cov ntawv sib nqus, cov ntawv yas thiab lwm yam khoom, thiab cov qauv ntawm cov ntawv yas siv UV luam ntawv tshuab txuas yog tsim tas li.

Nyob rau hauv xyoo tas los, LED UV tua kab thev naus laus zis tau maj mam tshwm sim, thiab cia siab tias nws yuav dhau los ua cov cuab yeej kho tshiab hauv lub neej yav tom ntej. Tus number case yog kho los ntawm LED lub teeb, nws qhov wavelength yog qhov nqaim heev (tam sim no 365 ~ 395nm ib nthwv dej), LED teeb muaj kev pab lub neej ntev dua, kev siv hluav taws xob ntau dua, kev siv hluav taws xob tsawg dua, thiab lub teeb ci LED tuaj yeem hloov thiab tua tau yam tsis muaj kev cuam tshuam ua ntej , Lub tshav kub hluav taws xob yog qhov tsis tshua muaj hluav taws xob, tsis muaj ozone tsim tawm, thiab nws muaj kev nyab xeeb dua, muaj kev tiv thaiv ib puag ncig thiab txuag hluav taws xob ntau dua li cov teeb tsa ua muaj muaj roj mercury ntau dua nyob rau hauv kev ua kom zoo UV number case tua. Raws li lub koom haum tshawb nrhiav kev lag luam Yole, lub ntiaj teb LED UV ua lag luam sib koom hauv UV kho cov teeb pom kev zoo yuav nce los ntawm 21% xyoo 2015 txog 52% hauv 2021, thiab UV-LED inks muaj kev txhim kho zoo yav tom ntej.

Los ntawm qhov pom ntawm cov qauv khoom, raws li lub zog zoo-txuag thiab kev tiv thaiv ib puag ncig kev ua tau zoo ntawm UV inks, qhov tsim tawm ntawm kuv lub teb chaws UV inks (suav nrog luam tawm UV inks thiab solder daim npog UV inks, thiab lwm yam) suav txog tag nrho nce hauv kev faib ua feem ntawm kev luam tawm tag nrho hauv tsev. 5.24% nce rau 9.17% xyoo 2018, muaj kev loj hlob sai, thiab cia siab tias tseem yuav muaj ntau chav rau kev loj hlob nyob rau yav tom ntej.
