(7) Xoob pobzeb (Tuav)
Nyob rau hauv cov ntaub ntawv ntawm nyem gravure printing, lub adhesion ntawm tus number case yog tsawg, thiab muaj me ntsis peeling. Hauv lithographic luam ntawv, tus cwj mem muaj qhov ua kom siab, daim ntawv tso tawm ntawm qhov dej, thiab ntxiv cov dej noo thaum lub sij hawm luam ntawv raug rhuav tshem cov dej ntawm daim ntawv, uas yuav tsum tsim kom muaj kab ntim. Lub sijhawm ntawm adhesion yog hais txog cov quab yuam generated thaum tus number case yog cais tawm ntawm daim pam thiab daim ntawv. Qhov saum npoo ntawm daim ntawv yuav tsum muaj ib qho kev quab yuam tus kab tawm, yog li ntau cov ntaub ntawv ntxiv hauv daim ntawv. Kev kho mob ntawm lub zog.
(8) Qhov txawv ntawm rooj
Yog hais tias tus ob chav mesh Hybrid forme yog siv los muab cov ntawv, qhov txawv ntawm qhov chaw yuav zoo heev txo.
(9) Hws noo
Daim ntawv yog ua los ntawm cov dej thiab yog ib co dej qab ntsev hauv cov qauv tshuaj. Nws yog ib qho yooj yim kom nqus ya raws, tso dej noo, thiab ncab thaum nws absorbs ya raws. Yog li ntawd, nws shrinks thaum ntub, uas yog, nws tsis muaj kev ruaj ntseg thiab feem ntau ua rau cov kab mob xws li curling, tsis, thiab shrinkage. Sab (Ntug Ntug) thiab lwm yam. Qhov ntsuas dej ntawm cov ntawv no muaj qhov sib txawv ntawm cov ntawv sau thiab cov cua ntub dej atmospheric. Feem ntau, 1/10 ntawm qhov txheebze ntawm cov txheeb ze yog qhov sib npaug ntawm cov ntawv txheej txheem. Cov ntaub ntawv uas muaj cov dej noo tsis tshua muaj dej txaus, uas ua rau daim ntawv caws thiab yoj, uas ua rau lub tshuab ua haujlwm tsis zoo thiab daim ntawv pub mis tsis zoo. Tsis tas li ntawd xwb, yog tias lub vojvoog yog siab heev, nws yuav tsum wetted, ua daim ntawv rau curl, shrink, thiab cov duab zoo nkauj tsis zoo, ua rau muaj teeb meem xws li kev ntxhib los mos. Txawm li cas los xij, qhov loj me me ntawm daim ntawv no tsis ruaj khov thiab tsis tuaj yeem muab tshem tawm. Yog li ntawd, qhov av thiab qhov kub ntawm cov nroj tsuag thiab kev cog cov nroj tsuag tseem ceeb heev. Nws yog ib qho tsim nyog kom muaj qhov kub thiab av noo kom haum rau qhov chaw.
(10) tus nqi pH
Lub tshuab luam yeeb ntawm daim ntawv luam tawm, cia cov ntawv ntawm pH ntawm daim ntawv, thiab ziab ntawm luam ntawv number case thiab cov emulsification ntawm cov dej noo dej muaj cov cawv zoo. Hauv ntawv, thaum lub pH ntawm daim ntawv yog 4 los sis tsawg dua, cov khoom nyob hauv tus lej hnov mob nrog lub tshuab hlau ntawm lub ziab kom tsim tau ib qho chaw. Thaum cov pH muaj 6 lossis ntau dua, cov dej ntub dej ntawm cov dej ntws thiab cov xaum xo yog nce, thiab cov kab xau yog tshwm sim. Yog li, lub pH ntawm feem ntau ntawm cov dej noo yog tswj txog 5.5.
Ntxiv nrog rau qhov saum toj no 10 yam tseem ceeb:
(1) Seb nws yuav hnav rau ntawm lub phaj
(2) Puas muaj hluav taws xob zoo li qub?
(3) Kev sib txuas thiab kev tuav pov hwm
(4) Txawm hais tias nws yog kab mob hauv daim ntawv caiv (flatter disease) yog qhov zoo tshaj plaws.
Qhov thib ob, qhov tshwm sim rau luam ntawv yog li nram qab no:
(1) Chav nyob
Cov ntawv luam tawm zoo yuav tsum tsis pub dawb ntawm cov pob txha, tsis thiab curls:
(2) Txiav
Yuav tsum yog qhov luaj li cas thiab square.
(3) Txawv Tebchaws
Cov khoom txawv teb chaws xws li ntaub ntawv xoob, pigments, fibres, thiab lwm yam., Yuav tsum tau muab tshem tawm los ntawm cov ntawv sau cov txheej txheem.
(4) Moisture cov ntsiab lus los yog txheeb ze ntawm cov av
Lub voj voos ntub ntawm daim ntawv yuav tsum yog tib yam li qhov chaw ua haujlwm.
(5) Ntsig txog kev rub sab nrauv
Lub zog ntawm daim ntawv yuav tsum txaus kom tawv tawv kom tawv nqaij thaum lub sij hawm luam tawm, ua rau tsis muaj teeb meem.
(6) Dej tsis haum
Nrog cov dej tsis xyuam xim, nws tuaj yeem hloov mus rau cov nyhuv dej ntawm lithography.
(7) Tus neeg muaj mob
Cov neeg muaj kev zoo siab ua haujlwm pabcuam tus number case rau ntawm daim ntawv.
(8) Cov duab ntawm daim ntawv yuav tsum ua kom tiav yam tsis muaj qhov muaj qhov me me, khawb, txhaws thiab tsis muaj dab tsi. Daim ntawv yob yuav tsum nruj nreem thiab cov npoo yuav tsum ca, thiab tsis muaj kab mob ntawv.
(9) Tsis muaj hluav taws xob zoo li qub
(10) Tsis txhob siv looj tsis hnav lub phaj.
Txawm hais tias qhov zoo ntawm daim ntawv coated zoo los yog tsis, ntxiv nrog rau qhov zoo ntawm lub zoo ntawm daim tseem ntawv, qhov muaj pes tsawg leeg ntawm txheej kuj tseem ceeb tshaj. Thaum twg ntau hom organic pigments ntxiv rau lub tsho los hloov cov dawb pigment uas nquag siv - av nplaum Cov ntawv coated ua yog proportional rau tus nqi ntawm cov organic pigment ntxiv ntawd cov xim dawb, dawb gloss, printing gloss, opacity, smoothness, thiab lwm yam. , uas txhais tau hais tias cov organic pigment yuav ua kom cov ntawv coated. xwm.
Thaum twg ntau hom organic pigments ntxiv rau txheej kom hloov cov titanium dioxide nrog tus nqi siab, siab dawb thiab siab txhim kho qhov Performance index, coated ntawv ua ntxiv nrog cov organic pigments ntawd cov ntaub ntawv dawb gloss, luam ntawv gloss thiab smoothness. Tus nqi yog proportional, tab sis raws li cov ntsiab lus dawb thiab opacity, nws yog inversely proportional rau tus nqi ntawm cov organic pigment ntxiv. Qhov no txhais tau hais tias hauv qee cov ntawv thov tshwj xeeb, txawm hais tias cov organic pigments tsis tuaj yeem hloov cov titanium dioxide, cov khoom ntawm cov ntawv coated tuaj yeem tswj tau. Ib theem twg yuav tsis txawv ntau dhau.
Thaum ntau hom organic pigments ntxiv rau cov xim muaj xim los hloov cov pigment, cov tshuaj calcium carbonate, cov ntaub ntawv coated yog xim dawb, dawb gloss, luam gloss, opacity, smoothness, Txhua yam yog proportional rau cov nqi ntawm cov organic Pigment ntxiv, uas txhais tau hais tias kev siv cov organic pigments yog ib qho kev tsis pom zoo los ntxiv txhim kho cov khoom ntawm coated paper.
Nyob rau hauv kev sib raug zoo ntawm qhov txheej txheem thiab qhov zoo ntawm daim ntawv coated, thaum cov organic pigment ntxiv rau txheej, cov khoom ntawm cov ntawv coated zoo dua li cov uas tsis muaj cov organic cov xim, thiab thaum ntawv coated yog nyob ze, organic ntxiv. Cov ntawv coated ntawm cov pigment tuaj yeem txo qhov nyiaj ntawm txheej. Thaum cov organic pigment yog tuab, cov txheej txheej yuav raug txo los ntawm kwv yees li 30%, thiab cov organic xim ntawm hom tom ntej yuav raug txo los ntawm kwv yees li 40%. Yog tias cov organic pigment tsis muaj hollow, qhov txheej nqi yuav raug txo los ntawm kwv yees li 45%. Qhov no txhais tau hais tias nyob rau hauv cov qauv ntawm daim ntawv pom kev, organic pigments tuaj yeem nqa nyiaj ntau heev.
Qhov zoo ntawm cov ntaub ntawv luam tawm tau muaj kev sib raug zoo nrog cov ntawv luam tawm, thiab qhov zoo tshaj ntawm cov ntawv luam tawm yog zoo rau daim ntawv xub thawj, xim thiab qhov chaw kho mob. Yog li ntawd, xaiv ib daim ntawv txaus ntseeg siab vim tias cov ntaub ntawv luam tawm yog tus nqi txuag thiab kev txhim kho. Tib txoj kev luam tawm zoo.
