Nws yuav siv sij hawm ib pliag xwb! Tam sim no cia kuv qhia cov txheej txheem tsim cov khob ntawv!
Ua ntej tshaj plaws, daim ntawv siv los ua cov thawv ntawv yuav tsum yog daim ntawv zaub mov. Cov ntawv feem ntau yog tuaj ntawm Tebchaws Europe thiab Amelikas, uas suav tias yog qib zoo tshaj plaws ntawm cov ntaub ntawv. Tom qab ntawd, nws yuav tsum tau coated nrog roj- thiab dej-resistant cov ntaub ntawv los ntawm txheej txheej ua ntej cov txheej txheem molding tom ntej tuaj yeem ua tiav.
Laminating yog muab ib txheej nyias nyias ntawm cov ntaub ntawv yas rau daim ntawv, kom lub khob ntawv tuaj yeem tiv taus roj thiab dej, thiab tuaj yeem tuav dej haus thiab kua zaub rau lub sijhawm ntev. Kev xaiv ntawm txheej txheej ntawm cov khoom laminating no kuj muaj feem xyuam rau cov yam ntxwv ntawm cov khob ntawv tom ntej. Qhov no yog kauj ruam ua kom lub khob ntawv muaj zog thiab zoo nkauj.
Tom qab txheej txheem txheej, cov qauv thiab xim yuav tsum tau luam tawm ntawm daim ntawv yob. Txoj kev luam ntawv tuaj yeem muab faib ua peb txoj hauv kev: intaglio, convex phaj thiab phaj tiaj. Tus nqi ntawm intaglio luam ntawv yog siab dhau, thiab nws tsis tshua siv tam sim no; convex printing siv cov ntawv yob rau kev luam ntawv tas mus li, uas yuav tsum tau luam ntau ntau. Lithographic luam ntawv txiav cov ntawv rau hauv daim ntawv rau kev luam ntawv, uas yog tsim rau kev tsim cov khoom me me. Tom qab siv tus cwj mem, lwm txheej dej thiab kev kho lub teeb yuav raug luam tawm raws li kev tiv thaiv.
Qee lub tuam txhab siv cov txheej txheem ntawm" luam ntawv hauv number case", luam ntawv thiab tom qab ntawd laminating, qhwv tus number case hauv laminating zaj duab xis. Txoj kev tsim khoom no muaj tus nqi noj ntau dua thiab yog li tus nqi siab dua. Txawm li cas los xij, tsis muaj teeb meem dab tsi ntawm kev luam ntawv yog siv, cov ntaub ntawv luam tawm ntawm cov thawv ntim khoom noj yuav tsum yog cov zaub mov qib kom muaj kev nyab xeeb thaum noj.
Cov ntawv luam tawm nkag mus rau hauv qhov tuag thiab tsim ib daim ntawv kiv cua, uas yog lub ntsej muag unfolded ntawm phab ntsa ntawm lub khob ntawv. Cov ntawv zoo li tus kiv cua yog sau thiab muab tso rau hauv lub tshuab tsim. Daim ntawv yog dov mus rau hauv daim ntawv khob zoo li sab nraum lub khob pwm. Nyob rau tib lub sijhawm, cov pwm muab cua sov ntawm cov pob qij txha ntawm daim ntawv, kom cov PE puas los ntawm cov cua sov thiab ua rau ib leeg, thiab hauv qab ntawm lub khob ntawv yog tom qab ntawd ntsia thiab ua raws. Tam sim ntawd tom qab cov pwm thawb lub qhov ncauj ntawm lub khob, daim ntawv ntawm lub qhov ncauj ntawm lub khob yog dov thiab tsau nrog cua sov los ua lub npoo ntawm lub khob ntawv. Cov kauj ruam tsim no tuaj yeem ua tiav hauv ib thib ob.
Lub khob ntawv ua tiav raug xa mus rau lub tshuab kuaj xyuas kom paub meej tias cov duab zoo li qub thiab tsis puas, thiab sab hauv yog huv si thiab tsis muaj stains. Lub khob ntawv ua tiav nkag mus rau hauv cov txheej txheem ntim khoom thiab tos rau kev xa khoom.
