"Seven Wolves (Ntawv Ntug)" Txhuas-Coated Paper Printing: 3 Qhov Tsis Zoo thiab Kev Ntsuas
Nrog rau kev nce qib ntawm thev naus laus zis tsis tu ncua, tib neeg cov khoom siv lub neej tau hloov pauv sai, thiab kev lag luam luam ntawv kuj tau nkag mus rau lub sijhawm ntawm kev loj hlob sai. Niaj hnub no, ntau yam khoom ntim ntim tau siv dav hauv lub neej txhua hnub, thiab kev lag luam xav tau kom zoo ntawm cov ntawv ntim khoom kom nce ntxiv. Cov kev hloov kho tshiab hauv kev luam ntawv thiab ntim tshuab kuj tseem coj cov teeb meem tshiab rau cov tuam txhab tsim khoom. Raws li cov qauv tsim khoom ntse, yuav tsum muaj kev tswj xyuas kom zoo dua kom ntseeg tau tias cov khoom luam tawm zoo. Tsab ntawv xov xwm no txheeb xyuas qhov tsis xws luag hauv cov txheej txheem luam ntawv ntawm "Seven Wolves (Fengmang)" metallized ntawv thiab tawm tswv yim txog kev daws teeb meem.
Kev luam ntawv ntawm "Seven Wolves (Fengmang)" metallized ntawv yog qhov nyuaj dua li cov ntawv luam tawm ib txwm, tab sis cov ntim tiav tuaj yeem nthuav tawm cov nyhuv tshiab thiab zoo nkauj (Daim duab 1). Metallized paper, feem ntau hu ua "cov ntawv ua tiav," yog ua los ntawm kev xa cov txhuas mus rau cov ntawv zoo tib yam ob -coated los yog ib qho -coated ntawv. Piv nrog rau ob daim ntawv zoo tib yam -coated ntawv, metallized ntawv muaj zog tensile zog, nws cov qauv ntawv yog me ntsis puas, thiab nto yog du, ua rau cov kev nyuaj ntawm kev tswj tus number case hloov thiab leveling thaum luam ntawv. Tau ntev, qhov tsis zoo hauv kev luam ntawv nrog cov khoom siv no tau nquag, muab cov kev xav tau ntau dua ntawm tus number case, ntawv, cov ntawv luam ntawv, thiab cov neeg ua haujlwm. Los ntawm kev tshawb nrhiav thiab kev tshawb fawb ntev ntev, tsab xov xwm no tsom rau kev sib tham txog peb yam tsis xws luag hauv kev luam ntawv "Seven Wolves (Fengmang)" metallized paper.
Daim duab 1: 'Seven Wolves (Fengmang)' Aluminium-Coated Paper
Daim duab qhia pom cov teeb meem dub
Cov cwj mem dub feem ntau yog ua los ntawm cov pa roj carbon dub, binder resin, thiab ntau yam khoom ntxiv. Cov resin yog siv los kho cov xim xim thiab ua kom tus number case viscosity, thaum additives kho tus number case qhov sib xws thiab ziab ceev. Kev tsim cov number case dub tau nruj heev rau txoj kev sib tsoo. Thaum siv tus cwj mem dub, qhov teeb meem tseem ceeb uas tshwm sim yog dub streaks hauv daim duab lossis cov ntawv nyeem, uas tuaj yeem muab faib ua ob hom: txuas ntxiv ntev streaks thiab luv streak trails (Daim duab 2).
Daim duab 2 Cov Ntawv thiab Duab Dub Rub Kab (sab laug: txuas txuas ntev rub kab, sab xis: luv rub kab tail)
Kev daws:
1. Ua tib zoo nplawm tus cwj mem ua ntej muab tso rau ntawm cov xovxwm, lim nws los ntawm 200-mesh npo, thiab ntxuav lub tais kom huv;
2. Siv 400-grit sandpaper los polish lub phaj luam ntawv;
3. Ntxiv 5%–10% ntawm qeeb- tus neeg ua kom qhuav raws li xav tau;
4. Nthuav lub squeegee 2-3 hli dhau ntawm cov hniav cushion, thiab tuav lub kaum sab xis ntawm lub squeegee thiab phaj ntawm 20℃-40 degree;
5. Tswj lub tshuab luam ntawv siab thiab squeegee clamping siab ntawm 0.20-0.25MPa;
6. Yog hais tias tsim nyog, hloov nrog ib tug nyuaj electrostatic roller.
Gloss Varnish 'Crescent' Defect
Gloss kua roj vanish yog cov pob tshab txheej ua los ntawm cov khoom siv hluavtaws, sib xyaw nrog lub hauv paus thiab cov khoom ntxiv, muab qhov ci ci, hnav tsis kam, thiab kev tiv thaiv. Piv nrog rau lwm cov inks, gloss varnish muaj qhov ntom ntom, yog li thaum lub sijhawm ua haujlwm txuas ntxiv, cov npuas tuaj yeem tsim, ua rau crescent - zoo li qhov tsis xws luag (Daim duab 3).
Daim duab 3 Varnish 'Crescent' Defect
Kev daws:
Nruab ib tus cwj mem hloov cov menyuam nrog lub cev muaj zog (Daim duab 4) kom sib npaug ntawm cov kua roj vanish rau lub tshuab luam ntawv phaj; Yog tias npuas loj, koj tuaj yeem ntxiv tus nqi tsim nyog ntawm defoamer kom tshem tawm lawv.

"Big Belly" Defect
"Big Belly" yog ib lo lus siv nyob rau hauv kev lag luam luam ntawv. Thaum tag nrho cov luam ntawv nro tsis zoo, yob ntawm daim ntawv yuav pib bulge ntawm cov npoo ib zaug nws raug mob rau ib qho chaw, uas yog vim li cas nws thiaj li hu ua "Big Belly." Coated aluminium ntawv twb du rau saum npoo, thiab tom qab UV kua roj vanish luam ntawv, lub substrate ua txawm smoother. Yog hais tias lub tshuab luam ntawv tsis raug kho kom raug, tshwj xeeb tshaj yog cov winding nro, qhov kev tsis zoo no tuaj yeem tshwm sim thaum cov txheej txheem qis qis (Daim duab 5).
Daim duab 5 'Big Belly' Defect
Kev daws:
1. Khaws qhov nro winding ntawm 0.10–0.12 MPa, vim tias qhov nro ntau dhau tuaj yeem ua rau daim ntawv wrinkling. Teem lub unwinding nro ntawm 0.15-0.20 MPa;
2. Tsis txhob hloov pauv loj rau daim ntawv sab nraud thaum luam ntawv;
3. Cov kua roj vanish yuav tsum tsis txhob khov heev. Siv lub khob # 3 Zahn los ntsuas thiab tuav lub viscosity ntawm 13-14 vib nas this;
4. Ua kom txo tau cov ntawv luam ntawv ceev.
Cov saum toj no yog cov teeb meem zoo nyob rau hauv aluminium-coated paper printing txheej txheem rau 'Seven Wolves (Fengmang)'. Hauv kev tsim khoom tiag tiag, cov neeg ua haujlwm yuav tsum tsis tu ncua sau txhua yam kev tsis zoo, tsis tu ncua thiab txheeb xyuas lawv, sau thiab tshuaj xyuas txhua pawg ntawm cov khoom lag luam, txuas ntxiv txhim kho teeb meem - tuav peev xwm, ua kom cov khoom tiav tiav, thiab ua kom zoo dua cov khoom zoo los txhawb lub tuam txhab kev txhim kho tsis tu ncua.
