Cov neeg txoj kev zoo nkauj yog cov kev txhim kho, thiab cov uas yuav tsum muaj rau cov teeb meem luam tawm kuj tseem muaj ntxiv. Yuav kom tau txais ib daim ntawv zoo nkauj, tus cwj mem xaj puas muaj cov cai hauv qab no (tseem hu ua xya yam ntawm lithography): 1. Xov zoo luam ntawv zoo. 2. Ntawv zoo heev; 3. Cov nab npawb zoo; 4. Tshawb sau ntawv; 5. Phaj ntiag tug; 6. Tej yam puag ncig uas ua tau raws li txoj cai; 7. Qhov tsim kom haum dampening. Thawj lub tswv yim ntawm cov ntaub ntawv luam tawm yog xim, uas yog hais los ntawm tus lej, vim li ntawd peb yuav tsum nkag siab txog cov kev faib tawm, kev sib xyaw, kev qhia, thiab kev sib raug zoo ntawm cov lej, uas yog qhov tseem ceeb rau kev xaiv kom khawm xim ntawm lithography.
Ua ntej, tus cwj pwm ntawm tus cwj pwm
Kev luam tawm yog kev siv cuab yeej technology nrog qib siab ntawm kev siv tshuab thiab nws cov duab zoo nkauj. Niaj hnub luam kev tshawb xav tau tsim kev ywj pheej ntawm kev ywj pheej. Cov txheej txheem ntawm kev luam ntawv yog kev sib txuas ntawm kev xa tus cwj mem los ntawm lub phaj mus rau ntawm daim ntawv los yog lwm yam khoom los ntawm kev quab yuam (xws li siab) los muab tsim cov qauv ntawv nyob rau ntawm daim ntawv lossis lwm yam khoom. Cov phev siv siv yog plaub hom ua raws li hom luam tawm: 1. lithographic printing ink; 2. nyem luam ntawv number case: 3, gravure printing number; 4. luam tawm kua mis luam tawm. Ntawm lawv, lithography accounts txog li 50% ntawm tag nrho cov luam tawm, thiab xaiv cov inks yuav tsum tau muab ntau xim.
Thib ob, qhov kev faib tawm ntawm cov phev hauv phev
Muaj ntau ntau hom lithographic inks.
Qeb peb, qhov yooj yim muaj pes tsawg tus lithographic number case
Cov cwj mem yog ib hom txheej txheem uas muaj cov xim pigment (xim, lwm yam), ib phau ntawv, cov ntaub so ntswg, thiab ib qho khoom siv ntxiv. Nws tuaj yeem luam tawm, ziab ntawm cov khoom tawm, thiab muaj xim thiab qee lub cev. Slurry nplaum.
Lub pigment yog ib qho khoom uas muaj cov khoom tsis zoo uas tsis zom rau hauv cov dej qhuav, yog cov dej uas tsis muaj roj lossis cov binder, thiab muaj xim. Nws tsis yog tsuas yog qhov tseem ceeb ntawm cov cwj mem, tiam sis tseem pom pom lub cev ntawm cov khoom. Rau ib tus twg, nws txiav txim siab cov xim, tuab, lub teeb pom kev thiab lwm cov khoom ntawm tus cwj mem.
Cov khoom sib txuas: Cov phom yog ib hom kua nplaum. Raws li lub npe qhia, nws ua raws li qhov txuas. Hauv cov cwj pwm, ib yam khoom xws li ib tug powdery pigment yog tov thiab kneaded, thiab tom qab ua av thiab dispersed, ib qho muab tshuaj txhuam zoo li adherend muaj ib yam fluidity thiab viscosity yog tsim. Cov pob txhub yog qhov tseem ceeb ntawm cov cwj mem kua, uas yog txiav txim siab lub cev ntws, viscosity, dryness, thiab printability ntawm tus cwj mem. Lub binder yog lub plawv ntawm tus number case.
Lub muab tub lim yog xim dawb, pob tshab, lub taub hau los yog cov yeeb tshuaj liab opaque uas tseem yog ib feem ntawm cov cwj mem. Nws tsuas yog siv cov ntaub ntawv kom sau cov ntaub so ntsaws. Ntxiv rau kev txo cov nqi ntshav thiab txo tus nqi, nws tuaj yeem kho cov khoom ntawm tus cwj mem, xws li tuab, fluidity thiab cov zoo li.
Additives: Additives yog cov khoom ntxiv ntawm tus cwj pwm uas tsis yog lub hauv paus loj. Nws kuj siv tau los ua ib qho khoom siv ntxiv rau cov khoom uas tau muab ua tiav lawm, raws li kev pab cuam luam ntawv los hloov lossis txhim kho tej yam khoom ntawm tus cwj pwm xws li ua lag luam, txhaws thiab zoo li.
Qeb plaub, cov cim qhia txog cov cwj mem
Tam sim no, cov kev tshawb xyuas ntawm tus number case tag los cov khoom tseem tsis zoo meej, thiab tseem muaj ntau yam tsis muaj kev txawj ntse thiab tsis zoo. Qhov kev sibtham tsis yog lus, uas yog hais, muaj ntau yam yuav raug txiavtxim thiab soj ntsuam los ntawm kev paub thiab los ntawm kev xav. Qhov kev sibtham tsis yog txhais tau hais tias qhov kev ntsuas no tsis yog sawv cev rau cov kev xav tau ntawm daim ntawv thov. Tsis tas li ntawd, qee cov haujlwm muaj qhov yuam kev loj hauv kev soj ntsuam. Yog li, muaj ntau txoj kev soj ntsuam thiab cov ntaub ntawv uas tsuas siv tau raws li kev sib piv ntawm tus txheeb ze, uas yog, qhov kev tshuaj ntsuam ntawm inks yog txheeb ze. Txawm li cas los xij, cov cim kev qhia txog cov cwj mem yog qhia rau kev luam. Ntawm no yog ob peb yam qhia tau hais txog kev luam ntawv.
1. Cov xim ntawm tus cwj mem. Ink concentration yog ib qho kev qhia ntawm nws cov ntsiab lus xim. Pigments feem ntau suav 2% ntawm tus lej ntawm tag nrho. Thaum luam ntawv, tus number case concentration yog loj, thiab tus nqi ntawm tus cwj pwm tseem siv tau, thiab xim ntawm cov ntawv luam tawm yog tuab; tsis li, cov xim ntawm cov teeb meem luam tawm yog lub teeb. Cov cwj mem kua ink concentration yog loj, thiab tus nqi ntawm cov zauv uas siv hauv kev luam tawm me me, tus number case yog nyias, thiab ziab yog ceev ceev, tshwj xeeb tshaj yog thaum luam tawm tsam loj ntawm tus cwj mem, tus cwj pwm ntawm cov ntawv luam yog tshwj xeeb tshaj yog zoo kawg, vim luam ntawv yog ua thaum luam ntawv nrog ib tug high concentration number. Tus number case txheej yog nyias thiab yoojyim, uas tuaj yeem txo qhov stickiness ntawm cov khoom luam tawm, thiab xim tshuav ntawm txhua xim yuav yooj yim kho. Muaj kev kawm me me hauv kev lag luam luam. Hauv kev luam ntawv, tus number case yog loj heev thiab zuj zus muaj tus lej sau. Tus number case yog me thiab zoo dua qhov luam ntawv. Qhov kev kawm no ua tau raws li lub tswvyim ntawm kev xav. Cov kev lag luam number case judges tus number case concentration los ntawm kev kuaj lub zog tinting. qhov loj ntawm. Cov txheej txheem muaj xws li cov nram qab no: muab cov zauv dub nrog cov cwj mem dawb tso, thiab muab cov zauv coj los pleev xim rau cov xim dawb los hloov tus nqi ntawm cov xim dawb ntawm tus qauv kom cov xim ob ntawm cov ntawv khoob hauv lub thawv ntawv tsis zoo. Qhov piv ntawm tus lej dawb ntawm tus qauv coj mus rau tus nqi dawb ntawm tus cwj pwm siv hauv tus txheej txheem yog qhia tias feem pua.
Qhov twg: S = feem pua ntawm tinting zog (100% nrog tus lej cim) A = naj npawb ntawm cov cwj mem dawb siv rau kev txhim kho txheem B = naj npawb ntawm cov cwj mem dawb siv rau cov kua qaub
2. Lub khob ntawm tus cwj mem. Tus cwj mem xaj khov yog tsim tawm raws li txoj cai ntawm lub luam ntawv xovxwm. Tus cwj mem ntawm tus cwj pwm viscosity yog kuaj los ntawm ib tug cwj mem xaj khov. Qhov siab tshaj ntawm cov xoos xaj ntawm tus cwj pwm yog hais txog cov quab yuam sib cais ntawm cov cuav pliav nruab nrab ntawm ob lub thawv ntawm qhov ntsuas lub zog. Lub viscosity ntawm tus number case muaj kev sib raug zoo nrog kev sov thiab kev kub ceev ntawm lub luam ntawv xovxwm. Lub khob ntawm tus cwj mem xau tau nce nrog qhov nce ntawm qhov khiav ceev ntawm lub npiv rau tooj liab, thiab txo qis nrog kev kub ntxhov. Lub xauv npo ntawm tus cwj pwm yog qhov tseem ceeb ntawm kev luam tawm, uas cuam tshuam qhov txav ntawm cov cwj mem ntawm lub luam tawm, lub thickness ntawm tus number case txheej ntawm cov ntawv luam, thiab qhov nkag mus. Tus nqi thiab qhov loj me me. Ntau tus kheej los sis viscosity tsawg heev ntawm tus cwj pwm yuav cuam tshuam qhov zoo ntawm cov ntawv luam. Thaum lub xauv npo ntawm tus cwj pwm loj heev, nws yuav ua rau kev ua yuam kev xws li kev hloov mis tsis zoo, kev hloov tsis zoo, cov ntawv pluag, thiab tsis tshua muaj overprintability. Yog hais tias tus viscosity tsawg dhau, nws yog ib qho yooj yim uas yuav ua rau ntau tus cwj pwm hloov, ya number case, dot enlargement, emulsification thiab floating ntawm tus number case. Thaum muaj qhov kub, viscosity ntawm tus number case yuav tsum tsis loj heev thaum luam ntawv ceev ceev, thiab vice versa. Tsis tas li ntawd, qhov sib txheeb ntawm qhov xim ntawm txhua tus cwj pwm xim yog xaiv raws li daim ntawv txiav txim. Nyob rau hauv ib txwm ua, tsis tas yuav tsum kho cov xim ntawm tus cwj mem. Yog hais tias nws yuav tsum tau kho, nws yuav tsum tau kho raws li nws cov viscosity. Additives rau taub hau. Feem ntau, thaum lub viscosity loj thiab qhov sib xyaw tsim nyog, cov khoom siv uas tsis muaj zog thiab tsis cuam tshuam yuav siv tau los kho kom haum. Feem ntau, thaum lub viscosity loj thiab qhov sib luag yog loj, ib tus neeg saib xyuas kev pab cuam uas txo viscosity thiab thickens yuav siv tau.
3. Dryness ntawm tus number case. Kev ziab ziab ntawm cov lithographic number ntawm daim ntawv yog tus txheej txheem uas muaj tus cwj pwm hloov ntawm ib qho kua roj dawb uas tsis yog-ncov qaum teb mus rau lub xeev ruaj khov. Lub lithographic number case qhuav kev lag luam muab faib ua ob qho yeeb yam; ib qho yog qhov kho ceev, uas txhais tau hais tias tus cwj pwm hloov ntawm lub xeev cov kua dej mus rau lub xeev ib nrab, uas yog, thaum cov khoom luam tawm tau siab rau qee qhov siab, nws tsis nplaum, thiab luam ntawv hu ua thawj zaug qhuav . Thawj zaug ziab ntawm tus number case yog txiav txim siab los ntawm cov qauv txhim kho rau cov qauv tsim. Thawj lub sij hawm ziab qhuav yog luv luv tab sis tsis qhuav. Qhov thib ob yog tias cov tshuaj conjunctiva uas yog oxidized yog qhuav, uas yog, qhov ziab tuaj yeem hais kom qhuav, ziab lub sijhawm ntev dua, thiab ziab lub sijhawm ntau tshaj 8 teev, uas yog qhuav qhuav. Kev ziab ntawm tus number case yog txiav txim los ntawm hom thiab qhov nyiaj ntawm cov khoom noj. Nws tuaj yeem hloov kho hauv qee yam. Tam sim no, cov lithographic inks yog txhua hom, thiab qhov kho ceev ceev ceev. Nyob rau hauv kev tshawb xav, lub quicker lub zoo dua, qhov zoo dua. Txawm li cas los xij, yog tias thawj zaug ziab sai sai, nws yuav ua rau lub teeb meem ntawm cov ntawv luam tawm. Qhov siab ntawm lub ci ntsa iab thiab kev ceev ntawm kev kho yog feem ntau yog qhov tsis sib haum thiab yuav tsum ua kom haum. Cov neeg yeej cia siab tias tus cwj mem yuav luam tawm ntawm daim ntawv sai sai, tab sis nws yuav tsis qhuav rau hauv tus ciam kua muag. Kwv yees li ntawm 80% ntawm tus cwj mem kua qoob loo ntawm lub sij hawm nyob hauv kev ua lag luam yog nruab nrab ntawm 16-30 teev. Yog hais tias lub sij hawm sib txuas zom sij hawm luv luv, nws yooj yim ua rau hauv lub tshuab. Nyob rau ntawm cov menyuam plhaub tuav, koj tuaj yeem xaiv cov cwj mem tsis muaj kabmob thaum uas luam tawm cov ntawv pov thawj thiab ntev version, tshwj xeeb yog tus number case nrog lub sij hawm ntev qhuav ntawm conjunctiva, tsis tuaj yeem peeling. Cov kaus poom uas tsis muaj kabmob tsis haum rau cov ntawv luam tawm luv luv (tsevneeg luam tawm ntev txog 12 xuab moos) lossis cov ntawv xa tuaj nrog cov ntaub ntawv pov thawj, uas yog pom zoo siv cov tshuab ntxhua ceev ziab sai.
4. Lub plhaub ntawm tus cwj mem. Lub gloss ntawm tus cwj pwm yog qhov sib piv ntawm cov teeb ntawm lub teeb pom los ntawm ib qhov chaw tshwj xeeb rau ib qhov chaw ntawm lub teeb thiab cov nyiaj ntawm lub teeb pom los ntawm pawg vaj huam sib luag, qhia raws li ib feem pua. Lub ci ntsa iab ntawm daim ntawv sau tau muab lub tswvyim zoo.
Feem ntau, qhov ntau dua qhov ci ntsa iab, qhov zoo dua qhov kev siv luam ntawv. Txawm hais tias cov gloss ntawm qhov teeb meem luam tawm muaj feem xyuam rau qhov absorbency ntawm qhov teeb meem luam tawm thiab absorbency ntawm daim ntawv, nws yog feem ntau yog txiav txim los ntawm tus cwj mem, thiab daim ntawv ntawm tus number case feem ntau yog nyob ntawm lub binder thiab cov pigment nyob rau ntawd. Cov phom thiab pigment hauv tus cwj mem yuav tsum muaj cov khoom zoo ua kom zoo, cov ntawv luam tawm zoo, thiab cov gloss siab ntawm cov khoom siv nws tus kheej. Xws li tus lej sau rau ntawm daim ntawv muaj lub siab tawv. Glossy inks zoo li yuav qeeb me ntsis thaum pib ntawm txoj kev ziab tshav kub. Thaum luam tawm ntawm ib lub tshuab xwb, tus cwj mem glossy yuav tsum raug tswj rau lub sij hawm dhau los, txwv tsis pub lub kauj ntawm qhov teeb meem tshwm sim.
5. Ua ntej ntawm tus cwj mem. Qhov ua piv txwv ntawm tus cwj pwm piv txwv tias cov pigment hauv tus cwj pwm, qhov loj me me ntawm qhov muab tub lim, thiab lub uniformity ntawm kev faib tawm hauv phau ntawv. Ink fineness thiab pigment
Qhov xwm ntawm qhov khoom (khoom siv) yog ncaj qha ntsig txog qhov loj me me. Thaum cov khoom mos mos thiab qhov sib txuas ntawm lub binder yog qhov zoo, nws yog ib qho yooj yim uas yuav tau ua kom yooj yim hauv av, thiab qhov tseem ceeb ntawm tus number case yog qhov ruaj khov dua. Thaum lub kaus mom ntawm tus cwj pwm tsis zoo, qhov phaj luam ntawv yog nws tsis qis luam ntawv phaj los yog ntawm cov ntawv luam ntawm cov ntawv luam tawm, cov ntawv teev khoob khoob khawm, qhov nthuav thiab cov ntawv teev tsis huv, thiab ntxiv rau. Tus cwj mem yuav tsum tau xaiv nrog lub mos fineness, thiab fineness ntawm tus cwj pwm yog zoo dua, lub net yog ntau dua thiab muaj zog, lub hwjchim xim muaj zog ntawm tib xim, tab sis cov nqi raug ntau rau cov nroj tsuag.
6. Lub teeb pom kev ntawm tus cwj mem. Nyob rau hauv qhov kev txiav txim ntawm tshav ntuj, cov xim ntawm tus cwj mem tsis tshua muaj qhov hloov. Koj yog lub teeb meem ntawm tus cwj pwm. Nyob rau hauv qhov tseeb, inks uas yog kiag li resistant rau lub teeb thiab invariant xim tsis muaj. Nyob rau hauv kev txiav txim siab ntawm tshav ntuj, cov xim ntawm tus cwj mem zis luam tawm tau sib txawv ntawm kev hloov, thiab lub teeb cias ntawm tus cwj pwm yog tsuas yog txiav txim siab los ntawm lub teeb tsis kam ntawm cov pigment hauv tus number case. Yog tias koj muaj kev tshwj xeeb ntawm lub teeb pom kev ntawm cov teeb meem luam tawm, koj yuav tsum muab rau lub cwjmem chav ua ntej ua ntej. muab tso rau pem hauv ntej. Nws tau luam tawm nrog cov cwjpwm uas muaj teeb tawm-resistant, thiab nws cov xim luam tawm yog kaj thiab yuav muab khaws cia rau ib lub sijhawm ntev. Ink luam tawm uas yog resistant mus rau lub teeb yog nws nquag mus rau fading thiab discoloration.
Tsis tuaj yeem yog lub zos ntev. Cov ntawv luam tawm, cov lus tshaj tawm, kev tshaj tawm, lwm yam, uas yog raug tshav ntuj ntev ntev, yuav tsum xaiv cov hauv qab uas muaj teeb pom kev zoo.
Lub teeb pom kev ntawm tus number case yog txiav txim siab los ntawm taug kev ntawm tus cwj mem ntawm ntawv thiab ziab nws nrog ib lub xim xim tshuab. Kev txiav txim siab ntawm lub teeb lub zog ua raws li lub teeb pom kev nrig xiav qauv yog yim, thawj theem ntawm fading yog loj, lub teeb meem tsis haum yog qhov phem, yim qib tsis yooj yim rau ploj, qhia qhov zoo tshaj plaws lub teeb tsis kam. Xim number case xiav ntawm lithographic plaub-xim cuav yuav tsum ncav cuag 7-8, thiab xim liab thiab daj yuav tsum yog nyob ntawm 3-5. Ink nrog tsawg lub teeb ua hauj yuav tsum them ntau xim thaum xim txuam thiab dilution. Hauv ntej, ntau hom phev nws txawv thiab lawv cov khoom sib txawv.
Qhov yooj yim tshaj plaws los txiav txim seb tus lithographic number case zoo los sis phem yog muaj peb lub siab thiab ib vas nthiv, siab lub teeb, siab concentration, siab printability, ceev ceev ceev, thiab feem ntau raws li tus qauv number case raws li tus cwj mem zoo. Ntawm chav kawm, qee cov luam tawm kuj yuav tsum muaj lub teeb pom kev zoo.
Nkag siab thiab txawj ua cov txuj ci yooj yim thiab cov cim kev qhia txog cov cwj mem, uas yog kev pabcuam zoo rau kev xaiv ntawm tus lej ntawm lub sijhawm luam ntawv. Thaum luam ntawv, tus number case yog xaiv thiab qhov zoo ntawm cov teeb meem luam tawm tau lav.
