Txoj kev ziab no muaj cov txheej txheem txhua tom qab muab hloov pauv. Hauv cov txheej txheem no, number case curing yog qhov tseem ceeb rau kev ua luam tawm tom qab thiab cov khoom siv uas luam tawm tau siv nyob rau hauv txhua txhua hnub.
Nyob ntawm seb tus lej ntawm tus cwj pwm, txoj kev ziab yuav muab faib ua lub cev ziab khaub ncaws, tshuaj ziab, thiab siv ob txoj kev ua ke. Cov phaw twj thiab cov kua roj vuas txawv yuav tsum tau sib txawv ziab los yog ob peb qhov tshuab ziab kom pom zoo kom ziab qhuav. Yog tias lub tshuab hluav taws xob thiab lub tshuab raj ultraviolet sib txuas rau ntawm ib lub tshuab luam ntawv, nws yeej yog txhua yam xav tau luam tawm, yog li nws yog qhov tseem ceeb heev.
Hauv kev pom ntawm nws qhov kev ua kom ziab, cov lus sau ntawm cov ntawv luam tawm yuav tsum ua kom tau raws li ob qhov kev txwv nram no: Ua ntej, tus cwj mem tsis tuaj yeem qhuav rau hauv cov quav cuav thaum uas luam tawm lossis kaw tsis ntev; ua ntej, tom qab luam ntawv, nyob rau hauv substrate Tus cwj mem xav kom qhuav sai thiab txhim kho.
Muaj ob peb yam tseem ceeb tshaj uas cuam tshuam tus ziab daig ntawm tus ziab: 1 cov lej ntawm tus cwj pwm (khawm pigment, binder thiab lwm yam khoom siv ntxiv); 2 cov khoom ntawm cov ntaub ntawv substrate (xws li permeability); 3 cov ntaub ntawv luam (ink number transfer, income) Ntawv qhov siab qhov siab, luam ntawv ceev); 4 cov kab mob climatic (sab hauv tsev sov, av noo); 5 kom sib xyaw kom tsis muaj zog (xws li cua ntws ntawm ntiv taw xoo, lub sij hawm tshwm sim, hom hluav taws xob, thiab lwm yam). Kub yog qhov tseem ceeb tshaj. Feem ntau hais lus, siab dua qhov kub, qhov zoo dua. Vim tias qhov siab dua, qhov kub ceev ntawm tus ncej number polymerization, lub zog ntawm tus cwj pwm me dua, qhov ntau txaus siab rau kev nkag mus, thiab ceev cov tshuaj hnyav no.
Paub qhov ua rau luam tawm hluav taws xob hluav taws xob, tus tswv teb kom yog
Hauv kev luam ntawv, qee zaum ntawv los yog cov ntawv luam sau ua ke sib koom ua ke thiab sib koom ua ke. Nws zoo nkaus li tias daim ntawv nto muaj qhov nqus khoom nqus thiab yuav tsis yooj yim cais. Cov phenomenon no yog luam tawm hluav taws xob zoo li qub. Nyob rau hauv cov huab cua qhuav, daim ntawv luam tawm yog tshwj xeeb tshaj yog nkag mus rau hluav taws xob zoo li qub. Nws tuaj yeem ua rau obstacles rau ntawv pub mis, ntawv xa thiab ntawv txiav. Tsis tas li ntawd, nws tsis tuaj yeem cia tau daim ntawv los yog nquag pom ob daim ntawv txheeb, cov ntawv khoob khoob, ntawv tsis tuaj yeem, thiab kev poob qis. Qhov tshwm sim txo cov khoom tsim tawm thiab cov khoom ua tau zoo. Yog li no, nws yog qhov tseem ceeb ntawm kev nkag siab txog kev luam ntawv zoo li qub thiab tswv cov tswv yim tiv thaiv kev lag luam.
Thaum twg daim ntawv muaj cov dej loj, nws tuaj yeem ua tus xaib hluav taws xob; conversely, thaum cov dej cov ntsiab lus yog tsawg, nws yog tsis, thiab daim ntawv yog prone rau hluav taws xob zoo li qub: Ua ntej, papermaking txheej txheem tsis haum. Hauv cov txheej txheem ntawv, vim cov ntsiab lus ntawm cov khoom siv roj ntsha (alum, sodium chloride, thiab lwm yam), cov ntsiab lus ntawm cov khoom siv (ntau thaj chaw, thiab lwm yam) ntau dhau lawm, thiab daim ntawv yog kub thiab kub thaum lub sij hawm ziab thiab calendering. Ntawv nrog high voltage static hluav taws xob. Qhov thib ob yog qhov tsis zoo ntawm daim ntawv. Yog hais tias muaj kev sib txawv ntawm qhov kub ntawm daim ntawv thiab qhov kub ntawm qhov kev ua haujlwm luam ntawv, daim ntawv yuav tsis cuam tshuam rau sau npe vim qhov kev hloov ntawm cov dej ntsiab lus, thiab nws yuav ua rau yooj yim hluav taws xob, uas yuav ua rau tsis txaus txhuam. Tsis tas li ntawd, daim ntawv tso tawm ntawv ua ntej luam ntawv luv heev, los yog cov stacking siab dhau heev lawm, kom daim ntawv thiab lub chaw luam ntawv kub tsis muaj lub sij hawm kom zoo, ua rau daim ntawv yuav tsum tau electrostatically them. Thib peb, txoj kev sib txuam luam tawm ua rau hluav taws xob tsis zoo. Thaum twg cov dej ntsiab lus ntawm daim ntawv yog obviously tsawg heev, daim ntawv yuav tsum excessively qhuav. Thaum lub sij hawm luam ntawv, vim muaj kev sib txhuam thiab kev siab ntawm daim ntawv pub, luam tawm, thiab lwm yam., Cov electrons sab nraum daim ntawv nucleus poob thiab generated, thiab daim ntawv yog electrostatically them.
Daim ntawv yog zoo li qub thiab qhov txawv yog txawv. Muaj ib qhov laj thawj, thiab muaj ntau yam teeb meem uas tsis tsim nyog. Txhua hom ntawv, txawm tias tib hom ntawm daim ntawv, qhov no thiab cov batch yav dhau los, qhov loj ntawm qhov hluav taws xob zoo li qub tsis yog tib yam, uas yog, qhov hluav taws xob yuav txawv. Ib qho tseem ceeb yog qhov hluav taws xob ntawm ob sab ntawm daim ntawv yog cov lus sib txawv thaum lawv tau electrostatically them, thiab qhov teeb ntawm sab xub ntiag thiab sab nraum qab ntawm daim ntawv yog cov teeb, uas yog, sab xub ntiag los yog sab nraum qab ntsej muag. Yog li ntawd, cov ntaub ntawv uas sib txuas lus nrog rau sab nrauv thiab sab nraum qab yog sib zog ua kom sib haum, thiab tsis yooj yim sib cais, uas ua rau muaj teeb meem rau kev luam ntawv, kev pub noj, kev xa khoom, thiab ntawv txiav.
Txhawm rau tiv thaiv kev cuam tshuam ntawm cov hluav taws xob hluav taws xob, peb yuav tsum xub tswj los ntawm qhov chaw. Rau cov ntawv uas muaj hluav taws xob zoo li qub, nws tuaj yeem raug muab ncua tseg, thiab sij hawm npaj yuav tsum muab txuas ntxiv. Qhov kub thiab av noo ntawm daim ntawv cia khoom yuav tsum raug tswj 18 ° C-20 ° C. Lub cev ntub dej ntawm cov pa yuav tsum yog ntawm 60-65%. Nws pab txo lossis tshem tawm hluav taws xob hauv daim ntawv. Secondly, daim ntawv yog siv los tshem tawm cov hluav taws xob zoo li qub los ntawm daim ntawv. Thaum siv daim ntawv ceev nrooj, siv lub tshuab ntawv los tuav cov ntawv uas muaj hluav taws xob zoo li qub. Thaum dai thiab ziab, xyuam xim rau kev sib koom tes ntawm lub cav ceev thiab cua tshuab. Thaum lub tshuab ceev ceev, qhov ntsuas huab cua sov yog tswj li ntawm 80-85%. Conversely, thaum lub tshuab ceev qeeb, huab cua txias cia rau 70-80. %. Xav tau kom raug caij nyoog: thaum dai, tuab ntawm txhua pawg ntawv yuav tsum tsis pub dhau 10 hli. Thib peb, cov cua kub hnyav thaum muaj xwm ceev tshem tawm hluav taws xob. Thaum muaj hluav taws xob hauv hluav taws xob thaum lub sij hawm luam ntawv ntawm daim ntawv txiav, cov "vapor method" yuav siv tau los ua kom qhuav sai daim ntawv kom tsis txhob muaj hluav taws xob hauv daim ntawv thiab ua tiav cov ntawv luam tawm sai li sai tau.
Tshem tawm cov hluav taws xob hluav taws xob ntawm daim ntawv kuj yog ib qho kev tshem tawm, uas yog los txhim kho cov ntawv kub, dej thiab siv cov niaj hnub tshem tawm, cov nyhuv yuav zoo dua. Txoj kev yog:
1. Nruab ib qho khoom siv cua txias rau hauv qhov Txiav Txim Siab los kho lossis tswj cov kub thiab qhov av ntawm qhov Rhiav luam ntawv raws li lub xov hluav taws xob zoo li qub. Feem ntau, lub khw kub yog hloov thaum nruab nrab ntawm 18 ° C thiab 20 ° C, thiab cov cua kub ntawm cov txheeb ze nyob nruab nrab ntawm 60-65%. Yog hais tias daim ntawv them ntau dua, kho cov ntsuas ntawm huab cua nruab nrab ntawm 80-85%.
2. Nruab ib qho tshem tawm tawm ntawm cov xovxwm. Tshem tawm cov hluav taws xob zoo ntawm daim ntawv los ntawm kev kho qhov teeb meem lossis qhov siab. Yog daim ntawv zoo li qub, siv cov khoom siv hluav taws xob los yog siab heev. Yog tias hluav taws xob tsis zoo, tsis txhob poob siab thiab siab heev.
3. Tshem tawm cov hluav taws xob hluav taws xob muaj hluav taws xob nrog cov isotope emitter. Lub hauv paus ntsiab lus ntawm isotope emission yog tib yam li cov hluav taws xob zoo li qub ntawm qhov kev tshem tawm zoo li qub. Nws yog ionize ntau molecules pa rau hauv ions. Vim hais tias cov ions muaj hluav taws xob sib txawv, lawv ua tau zoo cov neeg siv hluav taws xob. Thaum daim ntawv dhau los ntawm qhov chaw ion, qee qhov hluav taws xob zoo li qub tau them. Nws yog neutralized thiab lwm feem yog tshem tawm ntawm huab cua ions, yog li ua tiav lub hom phiaj ntawm tshem tawm hluav taws xob zoo li qub.
