Txoj kev loj hlob ntawm kev lag luam luam yog ze rau txoj kev loj hlob ntawm cov ntawv luam tawm, yog li kev tiv thaiv ib puag ncig ntawm tus kheej yog ib txoj kev loj hlob tseem ceeb. Yav dhau los, kev lag luam luam feem ntau yog siv cov tshuaj hnyav ua ntu zaws, tab sis nws cov pa phem yog pom tseeb rau txhua tus. Rau qhov kawg no, txhua lub teb chaws hauv ntiaj teb muab qhov tseem ceeb rau txoj kev loj hlob thiab kev tshawb nrhiav ntawm cov phooj ywg environmentally friendly, thiab Tuam Tshoj tsis muaj qhov tshwj xeeb. Kev luam tawm tshiab cov ntawv luam tawm cov ntawv luam tawm thiab cov khoom siv tsis muaj kev ua qias tuaj thiab tsis muaj cov pa phem tsim thiab siv ntau dua, thiab cov thauv ntsuab ntsuab nce ua qhov kev pom zoo thiab kev sib koom tes ntawm kev lag luam luam ntawv.
Yuav kom kawm tau ib puag ncig zoo, peb yuav tsum xub nkag siab txog kev tsim txom ntawm cov kab lis kev cai hnyav hauv qab rau peb:
Cov lej luam tawm muaj ib cov xim, ib phau ntawv, ib qho hnyav thiab ib qho yooj yim. Ntawm lawv, cov organic kuab nyob hauv phau ntawv yog tshwj xeeb yog teeb meem rau tib neeg lub cev. Organic solvents yuav tawg ntau cov natural resins thiab cov khoom cua. Lawv yog cov tseem ceeb ntawm ntau cov phaw, tab sis qee leej ntawm lawv tuaj yeem ua rau tib neeg lub cev thiab ua rog rog. Kev tiv tauj mus ntev yuav tuaj yeem ua kom qhuav thiab ntxhib tawv. Yog tias nws nkag mus rau hauv daim tawv nqaij lossis ntshav hlab ntsha, nws yuav phom sij rau cov neeg muaj ntshav. Cov qe ntshav thiab hematopoietic muaj nuj nqi. Txawm hais tias cov tshuaj no tau muab tshem tawm los ntawm kev ziab, qhov hnyav residual migrates rau hauv cov zaub mov thiab ua rau tib neeg lub cev. Yog hais tias siv cov thawv tshuaj siv los luam cov ntawv ntim thiab luam tawm cov khoom noj xws li luam yeeb, dej caw, khoom noj, tshuaj, dej haus, cov khoom ua si me nyuam, thiab lwm yam tshuaj lom teeb meem, uas yog ib puag ncig thiab tib neeg kev noj qab haus huv yog teeb meem heev.
Nyob rau hauv lub gravure thiab flexo hnyav hom inks, cov ntsiab lus ntawm cov organic hnyav yog siab li 40% mus rau 60%, thiab qhuav qhuav yog volatilized thiab qhuav, yog li cov ntsiab lus ntawm VOC (Volatile Organic Compound) nyob rau hauv qhov hnyav loj. Qhov ua kom muaj dej ntau ntawm cov organic solvents ua rau huab cua muaj paug thiab lwm yam teeb meem, thiab yog absorbed rau hauv cov pa nqus hlau, bronchus, ntsws los sis cov hlab ntsha, cov hlab ntsws lymphatic mus rau lwm yam hauv lub cev, thiab tseem yuav ua rau mob lom nyob rau tib neeg lub cev. Tam sim no, ob lub tuam txhab domestic thiab txawv teb chaws yog cov tswj hwm cov VOC cov ntsiab lus ntawm cov khoom siv xws li cov xim thiab thaub qab kom txo tau kev puas tsuaj rau tib neeg lub cev thiab ib puag ncig.
Hauv kev saib xyuas ntawm kev raug mob hnyav ua rau tib neeg, cov neeg tshawb nrhiav tau sib zog ua hauj lwm kom tsim kho cov teeb meem ntawm huab cua. Qhov no yuav tsum tau hloov qhov muaj pes tsawg leeg ntawm cov thev naus laus zis thiab siv cov khoom zoo rau tus kheej kom tsim kho tshiab ib puag ncig thaj tsam hauv. Txo cov emission ntawm VOCs thiab kev txhim kho cov kev siv zog ntawm kev siv hluav taws xob, cov neeg tshawb xyuas nyob hauv ntau lub teb chaws yog nce kev txhim kho hauv cheeb tsam no. Tam sim no, nws muaj peb yam tseem ceeb ntawm tus qauv hauv lub cev uas muaj feem ntau hauv Suav teb, uas yog dej-raws li cov phev siv, ultraviolet-curable inks, thiab haus dej cawv-soluble inks.
1, dej-raws li kua
Cov xaum dej uas yog dej yog ib hom kua roj number case uas npaj los ntawm kev siv lub pob cwj pwm (aqueous rein) ua ib phau ntawv, cov xim daj lossis xim zas xim raws li xim, tus dej ua lub ntsiab hnyav, me me ntawm ethanol raws li cov pa roj carbon monoxide -kawm, thiab ntau tus ntxiv ntawm cov khoom siv los ua cov dej hauv qab.
Qhov loj tshaj plaws ntawm nws thiab cov tshuaj hnyav hnyav hauv tshuaj yog qhov hnyav siv dej nyob hauv dej yog cov dej thiab ethanol, thiab VOC cov ntsiab lus tsis tshua muaj tsawg, uas yog qhov tsawg dua rau qhov chaw tsis zoo. Tam sim no, 95% ntawm cov duab luam tawm, 80% ntawm cov ntawv nyeem, thiab 40% ntawm cov yas yeeb yaj kiab luam tawm hauv Tebchaws Meskas yog luam tawm nrog cov dej hauv qab. Hauv lwm lub teb chaws, ntau thiab ntau dua dej hauv thom khwm yog siv ua ntim ntawv luam tawm. Nyob rau hauv xyoo tas los, Tuam Tshoj tau tsim ib co kev cai ntawm lub ntim khoom noj. Cov xwm txheej ntawm "ntsuab" luam yog kev txhim kho nyob rau hauv Suav teb, thiab dej-raws li tau tsim muaj sai hauv Suav teb. Tam sim no, cov dej-raws li cov thev naus laus zis hauv Suav teb muaj npe thawj zaug ntawm lwm cov ntawv luam tawm tom qab ntawm 35%. Nrog rau kev tshawb nrhiav cov neeg tshawb fawb, ntau hom dej sib xyaw kuj tau nce ntxiv, xws li cov lej yas, fluorescent number case, pob tshab npog, hluav taws xob-resistant number case, kaj cuav, dej kub thiab nyiaj number case thiab dej raws Cov kua roj vanish xees tau thov. .
Qhov tseem ceeb tshaj plaws ntawm cov kev siv thaj tsam ntawm cov dej hauv cheeb tsam hauv Suav teb yog flexographic printing, gravure printing thiab screen printing. Vim tias cov ntsiab lus tsis tshua muaj VOC nyob rau hauv qhov hnyav, tsis yog tsuas yog kev ua qias tuaj rau qhov chaw atmospheric me me xwb, tab sis kuj muaj cov tshuaj lom ntawm qhov seem ntawm daim ntawv luam tawm tsawg. Yog li, feem ntau ntawm cov khoom uas siv cov aqueous number case yog cov khoom ntim, ntawm cov khoom ntim, luam yeeb thiab dej cawv, cov menyuam yaus cov khoom ua si thiab cov zoo li tus account rau feem cuam tshuam.
Txawm hais tias cov dej hauv lub hauv paus tau siv ntau hauv cov ntawv luam ntawm coated paper, dawb ntawv qhia txog, cov ntawv thaij thiab cov yas yeeb yaj kiab, ntau lub ntim khoom lag luam tsis kam txais yuav nws vim nws raug nqi; thiab tseem muaj qee cov teeb meem hauv kev luam tawm ntawm number case, xws li number case Nws yog ib qho yooj yim rau qhuav ntawm cov kabmob anilox, uas cuam tshuam tus uniformity ntawm number case hloov; tus number case yog yooj yim rau ua npuas ncauj thiab cuam tshuam rau xim xim; cov dej tsis haum, hnyav ua haujlwm thiab ua haujlwm tsis zoo ntawm tus number case yog cov neeg txom nyem. Qhov no yuav tsum tau cov neeg tshawb xyuas los tsim cov kev tshawb fawb kom cov dej hauv lub cev tsim muaj ntau dua.
2, UV tua cwj mem
Ultraviolet light-solid number yog ib hom energy-saving environmentally-friendly printing number case uas tau tsim hauv lub xyoo tas los, tseem hu ua UV number case. Cov ntawv no yog irradiated nrog ultraviolet rays ua rau polymerization ntawm tus number case binder yuav tsum qhuav. Nws yog dawb ntawm cov organic solvents tsis taus thiab yog hnyav dawb. Yuav kom tshem tawm cov cwj mem kua voos ntawm VOC thiab ua raws li txoj cai ntawm cov huab cua zoo, cov luam ntawv maj mam txais UV number case technology los luam cov khoom, ces UV inks tau sai heev nyob hauv ib qho chaw hauv khw.
UV phom kuj tseem muaj cov xim, cov ntaub ntawv, thiab cov ntaub ntawv pabcuam. Txawm li cas los xij, cov kab los ntawm cov binder yog txawv ntawm cov xim xoos hnyav.
Los ntawm kev sib piv ntawm cov kab kos ntawm UV number case thiab cov hom hnyav ntawm tus cwj pwm, UV number case uas tau kho los ntawm ultraviolet irradiation los ua kom muaj pawg neeg, thiab hom hnyav ua pa hnyav thiab qhov hnyav uas qhuav los ntawm oxidative polymerization reactions uas yog infiltrated rau hauv daim ntawv los ntawm cov hnyuv rau ob peb teev. Muab piv txwv nrog cov dej uas muaj dej raws li uas tau qhuav los ntawm evaporation ntawm dej thiab txeem ntawm daim ntawv, lwm yam khoom yog txawv tshwj tsis yog rau cov pigment. Lub ntsiab ntawm cov phom yog photoinitiators, prepolymers thiab reactive monomers. Lub curing mechanism ntawm UV tus cwj pwm yog tias cov thaij duab nyob rau hauv cov cwj pwm yog ncaj qha los cuam tshuam los ntawm lub teeb ci ultraviolet, thiab cov pib lub plhaub mog yuav muab coj los ua ib qho radical, uas pib tig cov duab polymerization ntawm cov kev ua haujlwm hauv cov prepolymer thiab cov reactive monomer. Cov tshuaj tiv thaiv cov ntaub ntawv tawm ntawm cov kabmob tawm qauv, ua rau cov khoom siv yees duab ua rau cov yeeb yaj duab txuas ntawm kev sib txuas ntawm cov roj chiv, hloov cov kua hluav taws xob, thiab thaum kawg ua ib lub cwjmem uas tsis muaj zog, uas yog ib txoj hauv kev kom qhuav sai .
Thaum tam sim no, UV number case lawm los ua ib tus lej ntxiv ntawm kev siv tshuab, thiab nws cov pa pa tawm yog yuav luag xoom. Ntxiv nrog rau hnyav hnyav, UV inks muaj qhov zoo ntawm kev ceev ziab kom ceev, khaus npua, ntshiab dots, kaj thiab qaim cwj mem, zoo tshuaj lom neeg thiab tsis muaj tshuaj. Raws li kev txheeb xyuas, xyoo tso tawm ntawm UV number case yog kwv yees li ntawm 16,000 tons hauv Nyiv, txog 18,000 tons hauv Tebchaws Europe, thiab txog 19,000 tons hauv North America. Nws kuj yog siv dav hauv kev ua haujlwm, flexo, gravure, tshuaj ntsuam luam tawm thiab inkjet luam tawm hauv Suav teb.
Cov Kab Mob UV hauv cov dej yog cov kev qhia tshiab hauv cheeb tsam UV. Prepolymers hauv cov pa UV cov pa phem feem ntau yog khov thiab yuav tsum tau diluted nrog cov tshuaj reactive diluents. Thaum lub sij hawm siv cov tshuaj tua kab no tseem siv tau ntau hom tshuaj tawv nqaij thiab toxicity, thaum tsim cov roj uas tsis muaj viscosity prepolymers thiab tsis tshua muaj toxicity reactive diluents, lwm txoj kev loj hlob yog kawm anqueous UV inks, xws li, dej. Thiab ethanol ua ib yam tshuaj, kom qis toxicity thiaj ua tiav nrog cov VOC emissions. Cov kaab mob UV ua paug tau tsim tau zoo thiab siv nyob rau hauv cov tshuab luam ntawv luam tawm.
Tsis tas li ntawd, cov ntaub ntawv tseem ceeb hauv UV-cwj pwm kuj yog ib qho kev cia siab rau txoj kev loj hlob ntawm UV. Piv txwv nrog cov dawb radical photocuring system, qhov cationic photocuring system tsis cuam tshuam los ntawm oxygen inhibition, muaj qhov zoo ntawm qhov dej cwj pwm, muaj tsawg dua rau cov tib neeg tawv nqaij, muaj lub siab me me hauv lub ink number txheej, muaj me ntsis ntim shrinkage, thiab tau zoo thiab adhesion. Nws tau los ua ib lub npe kub nyob rau hauv cov ntawv tshawb nrhiav thiab kev loj hlob. [txuas ntxiv]
3. Cuaj khaum cawv kua qaub
Cov cwj pwm uas tsis yog phenyl cawv plhaws, uas yog lub luag hauj lwm hauv plhaws luam ntawv, kuj yog ib hom kua number case nrog me ntsis paug, thiab tsuas yog siv cov khoom noj, haus, haus luam yeeb thiab dej cawv, thiab ntim thiab luam ntawv ntawm cov khoom siv txhua hnub nyob rau hauv kev sib cuag nrog tib neeg lub cev.
Rau ib lub sij hawm ntev, nplua maum npau luam ntawm lub hnab ntim khoom hauv Suav teb cov ntaub ntim khoom sib xyaw yog los ntawm cov kua roj carbon dioxide uas zoo ib yam. Vim qhov kev tso tawm lossis qhov seem ntawm tus nqi ntau ntawm toluene, nws yuav ua rau muaj kev puas tsuaj rau cheeb tsam thiab kev tsim khoom, nrog rau tib neeg kev noj qab haus huv.
Qhov hnyav uas siv hauv tus cwj mem zauv feem ntau yog butanone, xylene, toluene, butanol los yog cov zoo li. Tshwj xeeb tshaj tiam sis butanone, qhov tsis hnov tsw tsis tshua muaj zog. Txij li thaum cov xim xoo pob zeb me me thiab muaj zog heev, tab sis lawv muaj cua sov thiab qhuav thaum lub sij hawm luam tawm, feem ntau lawv tsis tau qhuav vim lub sij hawm luv luv thiab kev kub ceev, tshwj xeeb tshaj yog rau cov teeb meem loj uas muaj lub tsam loj thiab txheej txheej. Muaj ntau cov tshuaj solvents seem. Cov kua dej ntawm cov residual residual yog coj los rau cov txheej txheem compounding, uas yog qhov yooj yim khiav tawm tom qab kev sib xyaw, thiab yuav maj mam mus thiab nkag mus rau, yog li cov ntxhuav seem yuav tsum muab ceev kom tsawg.
Cov cwj mem kua cawv ester muaj cov yam ntxwv ntawm cov ntxhiab tsw, tsis muaj benzene, ketone, thiab lwm yam, thiab cov ink industry tau ua hauj lwm kom loj hlob zoo li no tus cwj mem kua-soluble uas tsis tshua muaj polluting rau ib puag ncig. Cov cawv dej caw tau pab peb daws qhov teeb meem ntawm qhov khoom noj khoom haus tau txais los ntawm benzene thiab benzene seem hauv cov tshuaj toluene. Zus tau zoo ntawm cov phooj ywg zoo xws li cov phooj ywg muaj zog zoo heev ua kom muaj kev sib tw ntawm cov ntawv nplaum loj hauv lub tshav pob ntawm cov nplais yas yob luam ntawv. Nyob rau hauv Nyiv, Kaus lim qab teb thiab Qab Teb Asmiskas, cov toluene inks tau raug tshem tawm thiab hloov los ntawm kev haus dej cawv sib tov. Nyob hauv Tebchaws Europe, nws xav txhawb kom cov ntawv luam tawm thiab cov ntawv nplaum nplaum luam tawm tsuas yog siv cov cawv dej (soluble inks) xwb (txwv tsis pub cov hmoov benzene-soluble inks); nyob rau hauv Suav teb, cov kua cawv-soluble number case gravure luam kev lag luam kuj tau maj mam hos. Nws yog yav tom ntej, txoj kev loj hlob ntawm cov thev naus laus zis hauv Suav teb yog qhov sib xyaw uas siv roj carbon-soluble yuav raug hloov los ntawm cov cawv dej caw.
Ib tiam tshiab ntawm non-benzene cawv-soluble environmentally friendly inks tau tsim lub ntiaj teb tshiab rau cawv dej-soluble inks. Cov cwj mem yog tsim los ntawm nitrocellulose dej cawv thiab lwm yam tshuaj txhuam hniav uas muaj xim tsis muaj tshuaj lom thiab anhydrous ethanol. Nws siv tau rau high-speed printing on gravure tshuab. Nws qhov loj tshaj plaws yog tias nws tsis muaj benzene, thiab nws cov nqi yog tsawg thiab nws yog haum rau luam tawm. Ntau yam, cov nyhuv luam tawm thiab kev sib zog ua ke yog qhov zoo tshaj plaws rau cov phooj ywg environmentally inks hauv cov khoom noj khoom haus thoob ntiaj teb. [txuas ntxiv]
Tib lub sij hawm, Toyo Ink Co., Ltd. kuj txhawb txoj kev loj hlob ntawm cov khoom xyaw uas tsis yog benzene dawb tab sis muaj ntau hom kev siv mis los ua kom tau raws li kev xav tau ntawm cov khoom noj khoom haus. Cov khaub noom no muaj peev xwm siv rau cov phom luam tawm rau ntau lub hom phiaj. Tom qab luam ntawv, lub hnab ntim tau qhwv thiab ua si tsis tau ntxiv ntawm lub tshuab hnyav; nws yog tsim rau yuav luag txhua hom yas yeeb yaj kiab thaum siv hauv cov ntaub ntawv ntim kab ntawv. Tus number case adheres nrees thiab siab, tsis cuam tshuam rau cov kabmob; cov nyhuv luam tawm zoo, tshwj xeeb tshaj yog lub teeb ci siab yog qhov zoo hauv cov cwj mem; qhov kev tivthaiv ib leeg siv tau, thiab lub lag luam tseem ruaj khov; qhov hnyav tom qab luam ntawv me me, cov pob no lav kom tau raws li lub tebchaws kev cai; Toluene thiab methyl ethyl ketone, qhov chaw ua hauj lwm muaj kev nyab xeeb thiab tu cev. Obviously, txoj kev loj hlob ntawm cawv-soluble inks nyob rau hauv Tuam Tshoj yog unstoppable.
Ntxiv rau cov dej hauv cov phoojywg, UV-raug lub cev thiab cov cawv dej-soluble inks, cov neeg tshawb xyuas tseem niaj hnub tsim tshiab hom environmentally-friendly inks, uas cov roj zaub raws li tau hais tias yuav tsum yog cov neeg sawv cev rau cov neeg sawv cev.
Cov kua roj naj npawb yog hais txog tus nab npawb ntawm tus qauv uas siv cov roj zaub uas siv cov roj zaub ua piv txwv ntawm cov roj thaij roj thiab lwm cov khoom xws li cov resins thiab cov pigments. Tam sim no, feem ntau yog siv ib hom roj kua roj naj npawb, thiab cov khoom siv yog khoom noj roj xws li roj salad. Cov xwm txheej sau luam tawm nrog cov kua xuv tooj ntawm lub cev tsis tsim cov tshuaj lom thiab tsim kev puas tsuaj uas ua kom tsis zoo rau lub chaw thaum siv thiab kev tsim rov qab, yog li nws yog hu ua environmentally friendly printed matter. Hnub no, qee qhov kev luam tawm siv cov kua roj hmab hauv Tebchaws Europe thiab hauv Tebchaws Meskas yuavtsum tau cim nrog lub cim-muag "SoySeal" los tsim kev sib raug zoo ntawm cov khoom ua tau zoo.
Soybean number case ntau dua cov yam ntxwv zoo dua li cov tshuaj roj av raws li cov tshuaj qub, yog li nws tau maj ua tus tshiab darling ntawm tus number case tom khw. Nws muaj qhov zoo li nram qab no:
A. Kev tiv thaiv zoo heev;
B. Poob kev ua haujlwm zoo heev;
C. Lub teeb zoo thiab kub;
D. Kev pov tseg ntawm cov ntawv pov tseg yog ib qho yooj yim;
E. Cov nqi luam ntawv thoob plaws yog tsawg;
F. Nyob rau hauv txoj kab nrog cov cai tswjfwm.
Tam sim no, soy roj roj muaj ntau hom ntawv luam tawm muaj nyob rau hauv kev ua lag luam, nrog rau ntawv xov xwm hauv koos pis, phais ntawv, thermosetting inks, txias pleev phais, luam ntawv cov ntawv luam tawm hauv ntawv, thiab letterpress inks. Vim tias qhov kev thov kom muaj qhov zoo nyob ntawm qhov chaw nyob thiab lub siab ua haujlwm tshaj tawm hauv xyoo tas los no, kev siv tshiab tus phooj ywg zoo tshiab soybean inks los hloov roj av hauv qab los xyuas kom meej tias thaj chaw huv thiab zoo nkauj yuav yog ib qho kev xaiv zoo tshaj plaws. Yooj yim los ua phooj ywg zoo.
Txawm hais tias cov roj ntsha kua roj muaj qhov zoo saum toj no, lawv tseem muaj qee yam kev tsis haum:
A. Tsawg kom qhuav qeeb
Raws li lub tshuab tam sim no muaj kev txhawj xeeb, nws yuav tsis tau hloov tag nrho cov roj av distillate nyob rau hauv cov ink formulation nrog roj zaub vim lub ziab kev ua tau zoo ntawm cov roj zaub hom roj. Yog li ntawd, lub hom phiaj ntawm txoj kev tshawb nrhiav thiab kev txhim kho hauv daim teb no yog los xyuas kom meej cov ntsiab lus ntawm cov roj zaub hauv cov ntawv luam tawm uas ua tau zoo thiab ua tau zoo.
B. Nce qua ntaub ntawv
Tsis yog txhua hom kev luam ntawv luam tawm zoo heev rau cov roj zaub zoo. Piv txwv, gravure number case. Vim tias cov phaw twj ywm yog cov neeg tsis haum qhuav, cov khi yas yuav tsum yog neeg tsis muaj zog, thaum cov roj hauv cov thauv muaj roj tsis tshua muaj siab thiab kub taw tes thiab cov uas tsis muaj dej cawv. Yog li ntawd, yuav ua li cas nthuav cov ntaub ntawv ntau yam ntawm cov roj zaub hom uas tseem yog qhov teeb meem ceev kom tau daws.
Hauv daim ntawv no, seb nws yog cov dej-raws li dej, UV-curable number case, kua cawv-soluble number case, los yog kua roj kua uas muaj roj raws li nws cov lej ntawm tus cwj pwm, hloov cov khoom xyaw hauv cov xim uas yog tshuaj ntsuab environmentally nyiam cov ntaub ntawv, thiab nws yog tus phooj ywg zoo. Cov hauj lwm zoo yog pom tseeb. Thiab tam sim no Teb Chaws Asmeskas thiab qee lub teb chaws Europe tau txwv kev siv cov kuab tshuaj sib xyaw nrog benzene, hloov cov thooj av hauv ntsuab. Yog li ntawd, txoj kev loj hlob ntawm tus phooj ywg environmentally friendly inks muaj feem xyuam zoo heev rau kev lag luam luam. Nws yog qhov kev pom zoo hais tias cov phooj ywg zoo nyob rau hauv lub cheeb tsam yuav yog cov qoob lag luam nyob rau yav tom ntej hauv cheeb tsam.
