Cov dej hauv cov phoojywg yog sib xyaw plaub hom tshuaj sib txawv, uas yog:
Coloring khoom - nws yog qhov muag pom zoo uas tso cai rau peb pom cov xim.
Resin - nws yuav hloov xim rau ntawm lub cev.
Additives - Nws yog ib qho ua ke ntawm qee cov ntaub ntawv coj los kho qhov kev ua tau zoo ntawm tus cwj mem.
Hnyav - nws txo viscosity thiab ua rau nws yooj yim mus rho cov number case rau lub cev thiab ces qhuav.
Ntawm chav kawm, qhov hnyav ntawm aqueous number case yuav tsum yog dej, tab sis qee tus neeg tseem tseem sib tov qee cov kua kuab tshuaj, los yog cov dej hauv qab.
Rau niaj hnub no, txoj haujlwm tseem ceeb ntawm tus number case yog los nthuav qhia lus lossis qhia txog qhov muag. Nws yog feem ntau ib daim duab zoo, yog li feem tseem ceeb ntawm tus number case yog xim.
Qhov xim yog ib qho ntawm cov dyes lossis pigments. Dye yog ib tug neeg sawv cev rau sawv daws paub thiab tuaj yeem pom hauv cov khoom noj khoom haus ntxiv thiab xim cwj mem. Txawm hais tias cov nyhuv luam tawm tsis zoo thiab nws yog yooj yim los ploj, qee cov ntawv luam ntawv thiab cov ntawv xov xwm luam ntawv tseem siv nyob rau hauv kev siv vim tias tus nqi qis.
Hnub no lub high-quality inks yog sib xyaw ua ke siv cov pigments, nrog rau cov kev pom zoo carbon blacks thiab loj npaum li cas ntawm dioxide. Qhov tseeb, qhov pom ntawm cov xim thiab nws cov khoom tuaj ntawm lub pob zeb uas nqa tuaj. Ntau tshaj ib puas pigments yog formulated hauv inks los npog cov spectrum ntawm tag nrho cov xim, tab sis, nyob rau hauv ib txwm siv, raug caseules raug txwv txog li 50.
Muaj ntau cov xim pigment nyob hauv lub ntiaj teb xws li BASF hauv lub teb chaws Yelemees thiab qee cov chaw lag luam me me. Cov khoom siv xim yog batch, tab sis cov xim ntawm txhua lub koom haum txawv me ntsis. Muaj plaub xim ntawm tus cwj mem xiav: xiav, magenta, daj, thiab dub. Txhua lub teeb muaj ntsis sib txawv, thiab tsis muaj ib qho qauv zoo. Hauv particular, cov xim uas cov Sab Hnub Tuaj thiab Western lag luam yog cov xim sib txawv. Piv txwv, tus cwj mem liab yog xiav xim ntawm Sab Hnub Tuaj thiab xim daj ntawm sab hnub poob.
Cov Pigments yog ib qho khoom siv kim heev uas ua rau muaj nqi ntau dua los ntawm qhov yuav tsum tau ua haujlwm dua thiab xim muaj zog dua.
Kev xaiv ntawm luam kuj raug rau kev xaiv xim. Piv txwv, hauv ib rooj ntaub ntawv tshwj xeeb, peb yuav tsum ua kom muaj xim xiav xim uas yuav muab luam tawm rau ntawm daim duab dawb, tab sis lub hnab ntawv daj yog siv los ua pov thawj.
Lwm feem ntawm tus number caseulation yog qhov hloov lossis qhov hloov lwm lub cev. Qhov tseem ceeb ntawm cov duab ntawm no yog hloov cov pigment ntawm tus txheej txheem luam ntawv mus rau lub substrate. Thawj kauj ruam ntawm cov txheej txheem no yog los ua kom cov tawv ntoo lo rau hauv cov lus sau los ntawm cov ntawv xov xwm, thiab tom qab qhov hnyuv ntxig los yog ua kom qhuav, cov khoom uas tau muab coj los ua kom muaj xim. Peb muaj ntau hom khoom noj xaiv los xaiv, thiab nws tsis yooj yim sua kom siv tsuas yog ib lub pob zeb xwb. Tej zaum peb yuav xav txog qhov yuav tsum tau muaj cov teeb meem uas tau sau nrog cov resins txawv, xws li: kev kub taub hau, kev quav tshuaj tiv thaiv, siab gloss ...
Raug resins rau aqueous inks yog:
• Tiv thaiv kom tsis txhob muaj dej tawm ntawm qhov tawv nqaij.
• Ib pob tshuaj uas tsis zom rau hauv dej.
• Cov hmoov txhuam tsev sib xyaw ua kua hauv alkaline.
Qhov thib peb ntawm tus cwj pwm muaj pes tsawg leeg yog "dej". Nws lub ntsiab kev ua haujlwm yog ua kom muaj tus cwj mem ntau dua cov kua dej, yog li ntawd tus number case yuav nqa tau los ntawm daim phiaj xwm txheej number case ntawm tus qauv rau lub luam tawm lub cev, thaum cov ntaub qhwv thiab cov pigment yuav coj mus rau qhov sau. Nyob rau hauv cov ntaub ntawv ntawm lub cev, cov dej yuav tsum tau muab tshem tawm, uas nyuaj rau cov yeeb yaj kiab uas tsis yog nqus, yog li tshem tawm tus nqi thiab ziab ziab yog qhov tseem ceeb hauv kev luam ntawv.
Cov dej hauv tus cwj mem tsuas yog siv rau cov organic solvents vim nws cuam tshuam qhov ziab ntawm cov dej kom qhuav thiab txo qhov solvency. Cov dej hauv tus cwj mem tsis ntxiv stagnation, thiab cov pH, qhov nyuaj, thiab qhov dej ntawm cov dej tag nrho yuav cuam tshuam rau cov cuab yeej kom qhuav. Tsis ntev ces peb tham txog cov pH ntawm cov dej.
Cov phaj nyaj yog qhov tsawg tshaj plaws hauv cov dej hauv aqueous, thiab lawv ntxiv yog qhov muag lossis feem ntau ntawm cov xaum xim. Nws kuj muaj ntau hom kev additives, thiab peb yuav tsum xaiv lawv cov kev ua haujlwm thiab muaj peev xwm ua kom muaj kev koom nrog lub xauv mog feem ntau. Cov additives muaj xws li cov vov ntom ntom nti, cov tshuaj tua kab, cov neeg ua haujlwm, cov khoom sib txuas, thiab cov zoo li.
Cia peb tham txog kev siv tej yam raw khoom, xws li hnyav hlau, tshuaj solvents, hluavtaws resins, thiab lwm yam., Uas yuav ua rau muaj teebmeem rau ib puag ncig. Kuv nco ntsoov hais tias qee tus neeg muag khoom tau hais ua ntej, thiab tsis txwv tsis pub siv cov ntaub ntawv zoo li no. Muaj ntau yam teeb meem nyob rau thaj chaw Es Xias. Txawm hais tias tsoom fwv cov cai thiab cov kev tswj hwm tsis yog tswj hwm, koj yuav tsum xav txog exporting.
Ib hom tshuab luam ntawv muaj pes tsawg leeg yuav:
· Hnyav 70%
· Xim pob tshab 10%
· Additive 5%
· Rein 15%
Tau kawg, qhov no tsuas yog qhov nuj nqis, thiab qhov kev txiav txim siab zaum kawg yuav tsum tau ua raws li tus qauv ntawm tus lej thiab luam ntawv zoo. Niaj hnub no, rau qhov zoo tshaj plaws luam ntawv, cov xim muaj peev xwm ntxiv rau 17%, uas txhais tau hais tias peb tuaj yeem xav txog qhov yuav tsum tau kho cov kab tsim nyog. Qhov tseem ceeb tshaj plaws rau lub tshuab luam ntawv yog kom ua tiav ib qho txiaj ntsig zoo ntawm qhov kev siv nyiaj; thiab kom muaj teeb meem kev noj qab haus huv thiab kev noj qab haus huv.
Lub tswv yim tseem ceeb ntawm tus number case yog twb muaj, tab sis kuv yuav tsum tshaj tawm tias qhov no yog qhov nyuaj version. Wb rov qab mus rau qhov teeb meem kev tawm tsam, thiab txhua lub caij uas peb tau tham txog yav dhau los yuav cuam tshuam rau kev tuaj yeem.
Feem ntau tus tub luam khoom yuav nug koj seb koj xav tau dab tsi, los yog dab tsi uas koj pom zoo. Txawm li cas los, number case viscosity yog qhov tseem ceeb, txawm tias nws yog ib txoj hauj lwm mus rau lwm txoj hauj lwm, los yog nias rau lwm qhov xovxwm, los yog lwm yam mob kuj muaj viscosities sib txawv. Nws nyob ntawm ob peb yam, txawv printing qauv, inked rollers, scrapers los yog txawv patterners thiab mesh thickness.
Qhov ntsuas tau yooj yim yog ntsuas hauv lub khob ntsuas, tiam sis kev tu xyuas yuav tsum tau muab ntsuas hauv qhov kub hloov thiab ntxuav thiab tiv thaiv ntawm lub khob ntsuas.
Raws li kev ziab, evaporation ntawm dej yog ib qho tseem ceeb heev, tshwj xeeb tshaj yog rau cov ntaub ntawv tsis yog khoom siv, uas siv tau lub zog los ua kom qhuav tau qhov hnyav. Cov av ntawm qhov dej yog qhov zoo tshaj ntawm qhov nro ntawm qhov dej thiab lub cev yuav tsum luam tawm. Dej tsim tau ib qho chaw tsawg kawg nkaus ntawm thaj tsam ntawm lub cev kom nws tsis tuaj yeem yuav tsum tau wetted. Kev ziab ntawm cov cwj pwm aqueous absorbs ob lub luam tawm lub cev thiab cov cwj pwm uas tsis yog-absorbed, thiab nws yog tseeb tias cov dej tsis absorbed ntawm lub luam tawm lub cev xws li cov yas yeeb yaj kiab. Txawm hais tias tus cwj pwm absorbed yuav nqus tau cov dej ntau ntau, yog tias cov dej thiab cov pob txha tsis nqhis thiab muab sib cais thaum qhuav, uas yog, lub peev xwm dej ntawm cov ntawv luam yog saturated, watermark ink tias tsis absorbs tus number case yuav tsis qhuav. Lub sijhawm no, yog tias muaj honing, yuav muaj kev hloov xim.
Qhov txiaj ntsig pH yog qhov tseem ceeb tshaj nyob hauv cov dej hauv qab. Tsis muaj kev tswj los yog pH tsis muaj tseeb yuav ua rau muaj teeb meem ntau. Lub pH yog ib qho kev ntsuas ntawm acidity thiab alkalinity ntawm qhov hnyav. Qhov pH ntau yog los ntawm 0 txog 14, tab sis nws tsis yog qhov yuav tsum tau ntsia rau ntawm tus xov tooj 6, 7, los yog 8 los yog 9, vim tias muaj 100, 800 lossis 900. Dab tsi yog qhov tiag tiag? Ntawd yog, tus nqi pH yuav cuam tshuam cov viscosity ntawm lub aqueous number case. Hauv hom ciav hlau aqueous, nws tuaj yeem pom los ntawm lub teeb uas feem ntau ntawm cov pH yuav tsum nyob nruab nrab ntawm 8 thiab 9.
Ob peb kauj ruam uas yooj yim los tswj tus cwj mem:
• Ua kom zoo ua ntej siv.
• Tshawb xyuas txog tus cwj mem xaj xaj ntawm cov xov tooj saum toj.
• Kho cov dej khov thiab rov qab txhim khu lub zog thiab pH.
