Kev dai khoob yog hais txog cov dej tsis txaus los yog tsis muaj txhij rau ntawm qhov chaw seem ntawm cov ntawv xov xwm thiab qhov kev txhim kho ntawm kev ua tau zoo lipophilic los ntawm lwm cov cuab. Qhov kev hu ncaj nraim ntawm tus number case txheej rau ntawm cov npoo ntawm cov npoo thiab cov ntawv xov xwm ntiav ua rau sab ntiv xoom ntais thiab qhov tshwm sim khov ntawm lub cwj pwm hloov. Feem ntau hu ua "qhuav version." Ib qho tseem ceeb ntawm qhov kev ua qias neeg ploj yog tias qhov siab tshaj plaws ntawm txoj hauj lwm yog tsau nrog lub hauv paus ntawm tus cwj pwm absorbing. Txoj kev tsis ua hauj lwm ntawm no yog qhov yooj yim mus nrhiav tau ntawm cov teeb meem luam tawm. Lub ntsiab yog kom paub tias qhov ua tsis tiav thiab nrhiav kev tsim nyog rau lub sijhawm thiab sai.
1, qhov teeb meem luam ntawv phaj
Cov ntawv xov xwm tsis tau muab luam tawm, thiab qhov teeb tsa muaj roj, feem ntau tshwm sim los ntawm kev tsis luam tawm. Yog hais tias qhov nyhav greasy yog hnyav, PS daim phaj yog vim tias qhov underexed dawb paug ntawm cov photolysis tsis yog txhij txhua. Los yog txoj kev loj hlob tsis txaus, qhov dawb paug ntawm cov teeb meem loj tuaj tsis tau ntxuav. Yog tias lub qhov muag pom kev ntawm lub teeb tsuas yog ib qho xwb, nws yuav yog raws li hauv qab no:
(1) Cov laus daim duab tseem nyob ntawm daim phaj xub thawj thiab cov khoom siv;
(2) Tshem cov hnub ziab tshav kub, ua haujlwm tsis zoo, hnyav loj loj los yog cov yeeb yaj kiab ntawm lub tshuab luam ntawv muaj kab mob nrog cov av, qhov chaw qias, tsis zoo, thiab kev loj hlob tsis yog pob tshuam;
(3) Lub hau ntawm daim ntawv tais sab nrauv tsis huv los yog tus neeg saib xyuas kev tiv thaiv tsis yog sib npaug;
(4) Uneven roj hmab los yog khij mis khov.
Hla tus txheej txheem: Yog hais tias lub phaj yog greasy, nws yuav tsum tau muab luam tawm. Yog hais tias lub phaj yog greasy thiab ua ib feem me me, PS phaj yuav tsum tau txo cov rog thiab qee cov ntawv Carav ntxiv rau cov tshuaj tsis haum.
2. Txhim kho pH tswj kev dampening kua
Qhov pH ntawm dampening kua yog loj, hydrophilic colloid txheej yog qeeb los ua kom muaj, thiab cov txheej uas tsis muaj kab uas tsis muaj peev xwm muab tsis tau rau hauv lub sij hawm, thiab dawb paug muab faib ua hydrophilic thiab oleophobic; pH tus nqi tsawg dhau, thiab lub phaj xuab zeb yog etched. Yog li ntawd cov nplais ntawm cov seem tsis txaus yuav ua kom txaus cov dej ua rau cov roj yuav tsis huv.
Ua haujlwm dhau los ntawm txoj kev: Thaum muab cov phom dampening, nws yog qhov yuav tsum tau tswj kom nruj tswj hwm tus nqi puaj, raws li hom phaj luam tawm, lub thickness ntawm lub printing number case txheej, tus nqi ntawm cov txhauv, qhov xwm ntawm daim ntawv, qhov kev cob qhia, qhov kub thiab lwm yam kev mob. Raws li ib txwm muaj, cov pH ntawm txoj kev dampening yog: qhov PS version yog li 4.5 txog 6.
3, tus number case rau cov laus laus
Txij li thaum tus cwj mem xuas ntim quav rau hauv lub tshav kub ntev ntev thiab nyob rau hauv kev sib txuas nrog dampening tov thiab kua cwj pwm, nws yog nws kub hnyiab, qhov chaw qhuav qhuav thiab conjunctiva, hydrophilicity enhanced, , thiab tus cwj mem ntawm lub phaj ntws tsis yog roj ntsha. Adsorption nyob rau hauv lub sij hawm, resulting nyob rau hauv greasy luam daim hlau;
Tshaj kom dhau txoj kev: feem ntau tshem tawm cov cuav quav rau cov nplaum, txhuam, tiv thaiv kev laus, thiab tswj kom nws cov ntaub ntawv txauv rov qab.
4. Lub siab ntawm lub taub hau dej thiab lub phaj ntawv luam tawm loj heev.
Lub siab ntawm cov taub dej thiab cov ntawv phaj siab loj heev, cov ntaub ntawm lub velvet poob nws cov elasticity, thiab cov kev sib txhuam nce, uas ua rau lub xuab zeb ntawm lub phaj coj, uas txav tus ruaj ntseg ntawm cov inorganic ntsev txheej, thiab cov seem yog nquag oily av;
Tshaj dhau txoj kev: tsim nyog kho lub siab ntawm lub taub hau dej thiab cov ntawv xov xwm, cov hlau nplaum nrog cov thickness ntawm 0.15 mus rau 0.2 hli thiab lub dav txog 20 txog 30 hli tuaj yeem tso tau nruab nrab ntawm cov thooj dej los yog nruab nrab ntawm cov dej cov menyuam thiab cov ntawv phaj ntawm ob hnub thiab hauv nruab nrab, nrog kev xav ntawm tes Muaj kev sib txhuam tsis sib haum, thiab nws zoo dua yog tias cov ntawv hlau tau rub tawm kom zoo. Tsis tas li ntawd, cov dej yuav tsum tau txhuam kom nquag siv, thiab cov vov dej ntawm lub velvet yuav tsum tau hloov nyob rau lub sij hawm tom qab poob nws cov elasticity.
5, tsis siv cov dej rau cov menyuam
Lub tsho loj tes ntawm cov dej hauv dej muaj cov roj hydrophilicity tom qab tau degreased. Txawm li cas los xij, vim muaj qhov tsis zoo siv, qhov dej ntawm cov taub hau dej npog yog thawj zaug uas tau ntsib nrog tus cwj mem los yog cov roj ntau ntawm cov dej tawm hauv qhov dej ntawm cov dej hauv dej tsis ntxuav thiab ntxuav hauv lub sijhawm. Lub suede maj mam tso nws cov qauv qub, thiab cov dej tsis haum thiab cov dej hauv cov dej muaj zog zuj zus, ua rau dej ntws. Tus lej number case yog kev puas tsuaj thiab roj;
Tshaj kom dhau txoj hau kev: them nqi los tswj cov dej noo ntawm qhov tsim kom tiv thaiv cov dej ntawm cov quav tsis txhob khaus rau ntawm cov dej me. Siv sij hawm siv cov kua qab ntsev ua kua ntsev kom tshem cov qaub av ntawm cov dej ntawm cov dej, thiab feem ntau ntxuav cov dej rau cov menyuam kom paub meej cov dej zoo hydrophilic;
6, lub siab ntawm cov ntawv xov xwm thiab lub thawv pam pwm loj dhau lawm
Kev luam tawm yog kev nyuab ntawm lub siab, tab sis lub siab ntawm lub phaj luam tawm thiab khawm pam pwm loj heev, uas yuav ua rau kev sib txhuam, uas yuav ua rau cov xuab zeb hnav thiab phaj kom ci tau, uas yuav ua kom lub plhaub ntawm lub phaj los tsim cov greasy. Hom kev txhuam no feem ntau yog los ntawm ob yam. Nyob rau hauv ib sab tes, qhov kev faib rau hauv ob sab phlu yog tsis tsim nyog, ua rau muaj ntau npaum li cas ntawm cov hle khi ntawm caj dab; ntawm qhov tod tes, nws yog compression.
Kev kov yeej txoj hauv kev: Cov hauv paus ntawm txoj kev ntseeg tau tias qhov kev txwv tsis txaus yog tsis muaj laminating, lub siab yam tsawg yog siv tsis zoo, lub thickness ntawm thawj zaug lev yog thwj kom raug thiab ntsuas, thiab qhov nyiaj ntawm compression yog txiav txim siab raws li cov khoom ntawm lub cab .
7. Lub siab ntawm cov ntawv xov xwm thiab cov tub ntxhais uas muab tshuab khawm loj heev.
Cov tub rog uas muaj lub plhaw feem ntau yog cov sij hawm tshaj plaws, thiab muaj cov phev dai saum lub hau rau sab nraud. Qee cov cwj pwm uas muab zauv los ua cov khoom ntub dej, tshwj xeeb tshaj yog cov xim ntawm chrome daj number case yog cov coarse. Thaum lub siab ntawm cov phaj luam ntawv thiab cov tub ntxhais uas muab tshuab hlau loj loj, txoj kev sib txhuam loj yog loj, yog li xuab zeb yog nws tus kheej. Cuam tshuam los ntawm hnav thiab tu dua, nws qee zaum tawm hauv khej xim tha xim.
Txoj kev kov yeej: Tuav lub siab ntawm cov ntawv xov xwm thiab cov tub rau cov tub rog, thiab kho lub siab ntawm cov tub ntxhais uas muaj lub plhaub taum los ntawm cov khoom phom los ntawm cov hauv paus hniav, thiab ua rau ob sab ntawm tus lej ntawm cov tub ntxhais kawm. Kuj pom qhov dav ntawm tus cwj pwm xaws: tus lej feem ntau ntawm cov tub ntxhais thiab cov phaj siab yuav tsum muab kho rau 5 ~ 6 hli.
8, ntawv tseem ceeb
Vim tias muaj pes tsawg daim ntawv: cov fibers, fillers thiab sizing tsis sib zog, cov zog ntawm daim ntawv tsis zoo, thaum lub sij hawm luam ntawv, daim ntawv no raug rau cov qoob loo sib zog, qhov chaw yooj yim tshem tawm cov hmoov, thiab ib txheej yog tsim rau saum npoo ntawm daim pam. Thiab dhau ntawm daim pam rau hauv plhaub taum pauv rau cov menyuam, cov dej rau cov phom luam ntawv, lub sijhawm ntev, cov ntaub ntawm cov ntaub ntawv, cov hmoov thiab muab ntaub qhwv thiab lwm cov impurities, cov kev sib txhuam ntawm cov hlua khaus, thiab cov nplais ntawm lub phaj luam tawm yog smeared. Hnav thiab kua muag rhuav tshem txheej hydrophilic, ua rau cov roj av mus qias neeg.
Hla tus txheej txheem: Ntxiv 6 # varnish thiab debonding tus neeg saib xyuas hauv moderation, tab sis tus varnish yog yooj yim rau dilute tus number case xim thiab ua kom fluidity. Kev kho mob yuav tsum tau noj thaum siv nws. Yuav kom tiv thaiv tsis tau tus kab mob qias neeg ntawm lub cev tsis huv, phaj tov yuav zoo ntxiv, thiab daim pam thiab lub phaj yuav tsum muab ntxuav tas li.
