Puas yog Kub Ink Printing Prone rau teeb meem? Nkag siab Qhov Ua rau hauv 5 feeb!

Puas yog kub number case printing muaj teeb meem? Nkag siab qhov ua rau hauv 5 feeb!

Kub number case yog number case ua los ntawm cov hmoov kub, thiab piv rau cov xim zoo tib yam inks, nws muaj xim hlau xim uas shimmers nrog lub teeb golden. Cov xim kub no muab kev nkag siab ntawm cov khoom kim heev thiab zoo nkauj, thiab feem ntau siv rau hauv cov khoom ntim khoom. Nws tsis tsuas yog beautifies cov khoom tab sis kuj nce nws cov nqi ntxiv. Txawm li cas los xij, txij li cov khoom siv tseem ceeb ntawm tus number case kub yog tooj dag hmoov, tshuaj lom neeg nws yog cov hlau nquag thiab nquag ua kom tsis muaj xim. Nyob rau hauv tsab xov xwm no, tus sau pib los ntawm cov muaj pes tsawg leeg thiab muaj pes tsawg leeg ntawm tus number case kub, tshuaj xyuas nws cov yam ntxwv, thiab, ua ke nrog ntau xyoo ntawm kev ua hauj lwm, tawm tswv yim ib co kev ceev faj rau kub number case printing rau koj siv thiab kev tshoov siab.

01

Cov yam ntxwv ntawm Jin Mo muaj pes tsawg leeg

Zoo li lwm yam inks, kub number case yog tsim los ntawm pigments thiab binders. Ntawm lawv, cov xim yog cov xim xim hauv tus cwj mem, muab tus cwj mem xim xim, thaum cov xim hauv cov xim kub yog cov hmoov hlau hauv av, uas yog cov hmoov ua los ntawm tooj liab thiab zinc alloys.

Cov ntsiab lus zinc hauv cov hmoov kub yog feem ntau nyob ib ncig ntawm 8% ~ 30%. Kub number case nrog zinc cov ntsiab lus ntawm 8% ~ 12% yog xim liab thiab yog ib txwm hu ua liab kub; kub number case nrog zinc ntsiab lus ntawm 20% ~ 30% yog xiav -ntsuab thiab feem ntau hu ua qingjin; thiab kub ntawm liab thiab xiav kub yog hu ua qinghongjin. Nyob rau hauv gravure printing, kub number case mix feem ntau siv 800 mesh kub hmoov, thiab nto ntawm cov hmoov hmoov feem ntau coated nrog surfactants kom ntseeg tau zoo dua kev sib txuas nrog cov resin binder.

Kev ceev faj rau kev siv tus cwj mem kub

Zoo li tus cwj mem zoo tib yam, tus number case kub yog dav luam tawm, tab sis vim qhov tshwj xeeb ntawm nws cov pigments, muaj qee qhov tshwj xeeb ceev faj thaum khaws cia thiab siv.

PART.01

Vim tias tus number case kub tau yooj yim reacts chemically nrog huab cua thiab dej vapor thiab ua rau tsis muaj xim, nws yog ib qho tseem ceeb uas yuav tsum tau ua kom zoo thiab tiv thaiv kev ntsuas thaum siv los tiv thaiv nws los ntawm huab cua. Cov hmoov uas tsis siv kub yuav tsum tau kaw nruj nreem;

PART.02

Vim tias cov khoom siv tshuaj ntawm cov hmoov kub tsis ruaj khov, kev sib cuag nrog cov kua qaub, cov hauv paus, cov pa roj carbon, thiab sulfides tuaj yeem ua rau muaj kev hloov tshuaj lom neeg sib txawv, txo cov hlau cov luster thiab tig cov xim kub xim dub. Yog li ntawd, thaum siv tus number case kub, tsis txhob luam ntawv loj - cheeb tsam hauv tsev coated ntawv los yog offset ntawv, vim hais tias cov ntawv ua los ntawm acid papermaking yog acidic, thiab tom qab luam ntawv, kub number case tsis tsuas yog discolors tab sis kuj poob nws gloss;

PART.03

Cov ntaub ntawv pabcuam rau kev sib xyaw kub number case yuav tsum tsis txhob siv cov kua qaub -cov ntaub ntawv, tab sis cov khoom nruab nrab;

PART.04

Kev siv cov number case kub yuav tsum ua raws li lub hauv paus ntsiab lus ntawm "kev luam ntawv raws li qhov xav tau," lub ntsiab lus ntawm kev sib xyaw ua ke yuav tsum tsim nyog rau kev luam ntawv tas li li ntawm 3 teev, kom tsis txhob muaj kev hloov kho ntau dhau ua rau cov hmoov kub nyob hauv cov roj ntev ntev, oxidizing thiab deteriorating thaum raug huab cua, thiab poob nws golden luster;

PART.05

Thaum luam ntawv kub number case, luam ntawv ceev yuav tsum tsis txhob ceev heev, vim hais tias yog hais tias lub tshuab ceev nce, cov kev sib txhuam kub ntawm tus number case roller yuav nce raws li, thiab kub number case tuaj yeem tig dub vim oxidation;

PART.06

Thaum siv offset luam ntawv, cov tshuaj dampening rau cov luam ntawv kub yuav tsum muaj cov kua qaub los yog cov resins kom tsis txhob muaj cov tshuaj tiv thaiv ntawm acidic dampening tov thiab cov hmoov kub, uas tuaj yeem ua rau cov xim dub thiab poob nws cov gloss;

PART.07

Thaum luam ntawv kub, cov roj hmab chais yuav tsum tau kho kom zoo, thiab lawv txoj hauj lwm yuav tsum tau kho kom raug kom tsis txhob muaj number case buildup los ntawm cov cwj mem tsis zoo thaum luam ntawv, uas tuaj yeem ua rau cov hmoov kub nyob twj ywm rau ntawm cov chais thiab, tom qab kev sib txhuam ntev, ua rau oxidation thiab discoloration ntawm tus number case.

PART.08

Semi-cov khoom tiav rau luam ntawv kub number case yuav tsum tsis txhob muab tso rau ntau dhau; txwv tsis pub, lub tshav kub tso tawm los ntawm tus number case thaum ziab tsis tuaj yeem dissipate sai, uas yuav ua rau oxidation thiab discoloration;

PART.09

Tom qab ntxuav lub tshuab lub thoob thiab cov menyuam, cov organic hnyav uas tseem tshuav ntawm nws qhov chaw tseem tsis tau tag nrho evaporated. Yog tias kub number case luam ntawv tau ua tiav tam sim ntawd, tus number case kub yuav hnov ​​​​mob nrog cov kuab tshuaj, ua rau tsis muaj xim;

PART.10

Yog tias luam ntawv kub ntawm lub hauv paus xim, ua tib zoo ntxiv cov roj kom qhuav kom tsis txhob overlapping tus number case vim lub hauv paus number case tsis qhuav thiab cuam tshuam cov xim glossy ntawm tus number case kub;

PART.11

Thaum luam ntawv nrog tus number case kub, lub hauv paus xim yog feem ntau luam tawm ua ntej, thiab lub teeb daj los yog fake kub number case uas muaj zog, zoo ib yam li tus number case kub, tuaj yeem xaiv. Thaum luam ntawv rau ntawm daim ntawv coated los yog ntawv nrog zoo gloss, siv pob tshab daj number case ua lub hauv paus ua haujlwm zoo dua. Thaum siv lub teeb daj, pob tshab daj, lossis cov xim kub cuav raws li tus cwj mem xim xim, txog 1% tus number case kub tuaj yeem ntxiv los txhim kho qhov ci ntawm tus number case kub;

PART.12

Yog tias kub luam ntawv offset luam ntawv tiav hauv ib qho mus, cov txheej txheem yuav tsum tau them nyiaj thaum lub phaj ua. Thaum ua cov phaj daj, 50% ntawm cov dots yuav tsum tau muab tso rau ntawm qhov chaw uas xav tau kub. Yog tias tsis muaj lub phaj daj rau ntawm daim ntawv luam tawm, koj tuaj yeem qiv xim lub teeb sov.

Hauv cov ntsiab lus, muaj ntau yam ua rau kub number case discoloration. Tsuav yog peb nkag siab thiab paub cov yam ntxwv thiab kev luam tawm ntawm tus number case kub thaum lub sijhawm khaws thiab siv, thiab siv cov txheej txheem zoo, peb tuaj yeem tsis tsuas yog tiv thaiv kom tsis txhob muaj xim, tab sis kuj txhim kho qhov zoo ntawm cov luam ntawv kub, yog li ua kom tus nqi ntxiv ntawm cov khoom.
