Cov kua zaub mov thawv ntim khoom yog tsim los ntawm cov khoom noj ua kua ua kua thiab cov neeg siv rau nws txoj kev yooj yim, kev tiv thaiv ib puag ncig, kev txuag lub neej ntawm cov khoom noj hauv tsev sov, thiab cov khoom noj thiab cov kua dej ntau hauv cov zaub mov hauv Suav. Txhua xyoo, muaj kaum tawm ntawm billions, nrog rau cov mis nyuj, tshuaj yej, kua txiv, haus cawv thiab lwm yam. Cov khoom noj khoom haus ua kua dej muaj cov cwj pwm txawv - cov khoom thaiv tsis muaj teeb meem tsis hais lawv cov khoom thiab cov txheej txheem ntau lawm. Cov khoom siv rau cov khoom noj yog nyob ntawm cov ntawv nyeem hauv cov zaub mov, thiab PE zaj duab xis txheej los yog txheej txheem txheej txheem txheej txheem them rau sab pem hauv ntej thiab sab nraud ntawm lub hauv paus ntawv los ntawm txheej txheem laminating los tsim cov khoom pov thawj thiab huv siab. Cov khoom thaiv siab feem ntau yog hu ua PE coated paper. Los yog txhuas ntawv txheej coated, uas yuav siv tau rau ntau txoj kev luam tom ntej los ua cov txheej txheem ntau hom khoom noj kua zaub. Vim tias txhua cov khoom noj ua kua dej tau sau ntau yam, cov ntawv yuav tsum muaj rau cov ntawv thawv ntawv sib txawv. Nws muab faib ua ob hom: ib lub kauj voj thiab ib qho carton. Lub taub hau yuav tsum muab luam tawm los ntawm flexo lossis gravure. Kev ua, ib qho luaj xwb yog tsim rau ntau txoj kev luam ntawv xws li flexo, gravure thiab offset printing. Nyob rau hauv ntau hom kev luam tawm, tus cwjpwm ntawm cov ntawv luam tawm ntawm cov zaub mov kev ruaj ntseg ntawm lub thawv khoom noj khoom haus tsis zoo li qub.
Thawj yog flexographic printing. Flexo luam ntawv yog ib tus qauv zoo ib puag ncig zoo thiab kev tu tsiaj luam tawm tam sim no uas pom zoo nyob thoob teb chaws. Cov ntawv phom sij feem ntau yog tsim los ntawm cov dej hauv qab. Cov diluents yog dej thiab ethanol, cov tshuaj tsis muaj tshuaj lom, muaj kev nyab xeeb siab, thiab qhov muag loj tshaj plaws hauv lub ntiaj teb. Qhov kev faib ua feem ntawm Tetra Pak tus Tetra Pak yog nyob ntawm hom luam ntawv. Txawm li cas los xij, acrylic resin nyob rau hauv cov tseem ceeb ntawm cov qauv siv dej uas muaj dej raws li tseem muaj cov kab ntau ntawm cov toluene thiab lwm yam khoom xyaw organic. Nyob hauv tus txheej txheem ntawm luam ntawv thiab laminating txheej txheem, luam ntawv number case yog khi rau ntawm daim ntawv los ntawm PE txheej. Toluene thiab lwm cov organic solvents yuav nyob hauv txhua daim duab. Cov ntaub ntawv coiled yuav tsum muab raus rau hauv hydrogen peroxide ua ntej yuav muab ntim hauv cov khoom ua kua. Cov tshuaj hydrogen peroxide yuav tsum raus hauv sab ntawm lub thawv rau hauv plev npoo los tsim ib txoj yas suab. Yog hais tias tus kab sealing tom qab tsis yog tshav kub-kaw, muaj micro-porosity, ntim. Tom qab lub npov tsim, cov khoom noj ua kua dej kuj tseem raus lub xauv kua mis, ces qhov ntawm cov cwj mem yog tso tawm rau hauv cov khoom noj ua kua ua rau muaj kev sib kis.
Gravure printing yog feem ntau siv ntim cov txheej txheem rau ntau tus thib ob- thiab kab thib peb cov kua ua kua (dej haus) cov khw muag khoom hauv Suav teb hauv xyoo tas los. Vim muaj kev loj hlob sai ntawm cov qauv siv hauv kev lag luam ntawm cov tub lag luam nyob rau xyoo tas los no, muaj ntau hom kev haus uas tsis muaj phenyl cawv plab hnyuv cev tau tsim, uas tuaj yeem siv rau kev luam ntawv thiab ua cov kua zaub mov. Txawm li cas los xij, xws li cov dej hauv qab, muaj cov kab uas toluene thiab lwm cov organic solvent nyob rau hauv cov xim uas tsis yog phenyl-soluble gravure. Cov ntaub ntawv tseem ceeb kuj muaj cov tshuaj toluene thiab lwm cov organic solvents uas tseem tshuav, txawm tias nws muaj kev tiv thaiv los ntawm ib txheej, yog hais tias nws yog ntug dej ntim rau lub sij hawm ntim. Lub sealing sawb tsis yog cua sov-kaw, thiab kua zaub mov kuj tuaj yeem tiv tauj nrog tus luam ntawv cim los tsim ib qho kev sib kis.
Kev xa ntawv tawm yog siv rau qhov tsim cov thawv ntawv sab nrauv. Raws li lub npe pom zoo, lub hnab ntim vov tsev yog lub vov tsev zoo li lub khob rau khoom noj khoom haus, uas muab faib ua peb hom: lub vov tsev tsis muaj qhov txav, cov nplais yas ci thiab yas yas. Nws yog tsim nyob rau hauv ib lub thawv ntawv nkaus xwb thiab muaj kev ua kom muaj tsawg dua. Nws yog siv nyob rau hauv semi-automatic packing ntawm cov kua zaub mov nrog cov khoom me me.
Tam sim no, offset printing inks yog feem ntau ua los ntawm hluavtaws pigments tsis muaj hnyav hlau, organic solvents thiab hluavtaws resins, thiab muaj kev nyab xeeb zoo. Txawm li cas los xij, hauv kev luam ntawv, vim tias cov ntaub ntawv yuav tsum tau muab pov tseg kom tsis txhob ua kom khaus, cov hmoov luam tawm (lub ntsiab feem ntau cov hmoov txhuv nplej siab thiab cov khoom siv ntxiv) yuav ua rau sab tom qab ntawm cov ntawv luam tawm, uas yog, sab nyob rau hauv kev sib cuag nrog cov kua zaub, yog ua ntej ua kua dej. Yog tias qhov dej tsis tsim nyog tau muab tshem tawm, cov hmoov av yuav yaj ua kua rau cov kua ua kom muaj qee yam kab mob. Lub hnab ntim ntawm lub ru tsev tsis tas yuav kub-seev nrog lub sealing sawb, tab sis ncaj nraim cov hlua ntawm lub ru tsev hnab, thiab kub-sib tsoo thiab tsevneeg nrog PE txheej ntawm daim ntawv, kom zoo tiv thaiv tus naj npawb ntawv thiab cov kua zaub mov. Ncaj nraim tiv thaiv kom tsis txhob muaj kev ua qias tuaj.
Hauv kev xaus, cov khoom noj khoom haus kua dej ua tiav hauv txhua hom ntawv luam tawm. Vim yog cov kev txwv ntawm cov khoom siv niaj hnub no thiab cov cwj mem kua ntau, muaj qee qhov kev pheej hmoo ntawm cov khoom noj muaj kua. Txoj kev siv rau kev tswj kuab paug muaj peev xwm tswj tau. Kev tsim cov txheej txheem, txhim kho qhov kev sim kom zoo, txo qee qhov muaj kuab paug, thiaj li ua kom muaj kev nyab xeeb ntawm cov zaub mov ua kua thiab tiv thaiv kev ruaj ntseg ntawm cov neeg siv khoom.
