Cov txheej txheem thawv xim: qhov ua rau thiab kev daws teeb meem ntawm cov xov lub thawv ntawv

Muaj ntau ntau yam ua rau qhov qhib ntawm lub thawv ntawv loj dhau tom qab tsim lub thawv xa ntawv. Cov yam tseem ceeb uas txiav txim siab tau yog ob yam: 1. Cov laj thawj ntawm daim ntawv, suav nrog kev siv daim ntawv yob, cov dej noo ntawm daim ntawv, thiab kev coj ntawm daim ntawv fiber. Qhov thib ob, cov laj thawj kev siv tshuab, suav nrog kev kho qhov chaw, kev tsim cov qauv, qhov tob ntawm kab indentation thiab hom ntawv imposition. Yog tias ob qhov teeb meem loj no tuaj yeem daws tau zoo, ces qhov teeb meem ntawm kev tsim cov thawv ntawv yuav raug daws raws li.

1. Daim ntawv thiab daim ntawv yog cov yam tseem ceeb hauv kev tsim cov thawv duab ntxoov ntxoo

Raws li peb txhua tus paub, feem ntau ntawm lawv siv daim ntawv yob tam sim no, thiab qee qhov ntawm lawv yog cov ntawv yob xa tuaj. Vim muaj teeb meem ntawm qhov chaw thiab kev thauj mus los, nws yuav tsum tau txiav hauv lub tebchaws, thiab lub sijhawm khaws cia ntawm daim ntawv txiav luv luv. Tsis tas li ntawd, thaum qee tus neeg tsim khoom muaj teeb meem hauv kev hloov pauv peev, lawv raug muag thiab yuav tam sim ntawd, yog li daim ntawv txiav loj. Tsis muaj ib qho ntawm cov seem yog tiaj tus thiab tseem muaj qhov nyiam curl. Yog tias koj yuav daim ntawv txiav ncaj qha, qhov xwm txheej zoo dua, tsawg kawg nws muaj qee yam txheej txheem khaws cia tom qab txiav. Tsis tas li ntawd, cov dej noo uas muaj nyob hauv daim ntawv yuav tsum tau faib sib npaug, thiab tib lub sijhawm yuav tsum sib npaug nrog qhov kub thiab av noo ib puag ncig, txwv tsis pub, deformation yuav tshwm sim tom qab lub sijhawm ntev. Yog tias daim ntawv txiav raug stacked ntev dhau thiab tsis siv sijhawm, cov dej ntsiab lus ntawm plaub sab yog ntau dua lossis tsawg dua li ntawm nruab nrab, thiab daim ntawv yuav khoov. Yog li ntawd, thaum siv daim ntawv jammed, nws yuav tsum tsis txhob stacked ntev dhau kom tsis txhob deformation ntawm daim ntawv. Tom qab lub thawv ntawv tau tsim, qhov qhib loj dhau thiab muaj cov yam ntxwv xws li cov fiber ntau ntawm daim ntawv. Cov ntawv fibers tau teeb tsa nrog me ntsis deformation hauv cov kab rov tav thiab loj deformation hauv cov ntsug. Thaum qhov kev qhib ntawm lub thawv ntawv sib luag rau cov fiber ntau ntawm daim ntawv, qhov tshwm sim ntawm qhov qhib bulging yog qhov pom tseeb heev. Txij li thaum daim ntawv nqus dej thaum lub sijhawm luam ntawv, tom qab kev kho qhov chaw xws li UV varnish, polishing, thiab txheej, daim ntawv yuav ntau dua lossis tsawg deformed thaum lub sijhawm tsim khoom. Qhov kev ntxhov siab ntawm qhov chaw ntawv deformed thiab qhov chaw hauv qab tsis sib xws. Thaum daim ntawv Deformation tshwm sim, vim tias ob sab ntawm lub thawv ntawv tau nplaum thiab kho thaum nws tsim, tsuas yog tias nws qhib sab nraud, qhov qhib yuav qhib ntau dhau tom qab tsim.lub thawv chocolate

Qhov thib ob, qhov kev ua haujlwm ntawm cov txheej txheem kuj yog ib qho tseem ceeb uas tsis tsis quav ntsej rau qhov qhib ntawm lub thawv xim tsim qhov qhib kom loj dhau.

1. Kev kho qhov chaw ntawm cov tshuaj ntim feem ntau siv cov txheej txheem xws li UV glazing, lamination, thiab polishing. Ntawm lawv, glazing, lamination, thiab polishing ua rau daim ntawv dhau los ntawm qhov kub siab dehydration, thiab cov dej ntsiab lus yog txo qis heev. Cov fibers yog brittle thiab deform. Tshwj xeeb tshaj yog rau cov ntawv cardboard nrog cov dej-raws li tshuab-coated zaj duab xis ntawm ntau tshaj 300g, qhov ncab ntawm daim ntawv yog pom tseeb dua, thiab cov khoom laminated muaj qhov tshwm sim ntawm sab hauv khoov, uas feem ntau yuav tsum tau kho artificial. Qhov kub ntawm cov khoom polished yuav tsum tsis txhob siab dhau, feem ntau tswj tau qis dua 80°C. Tom qab txhuam, feem ntau nws yuav tsum tau muab tso rau li 24 teev, thiab cov txheej txheem tom ntej tsuas yog tuaj yeem ua tiav tom qab cov khoom txias tag, txwv tsis pub cov hlau tawg yuav tshwm sim.

2. Cov thev naus laus zis tsim cov phaj txiav tuag kuj cuam tshuam rau kev tsim cov thawv. Kev tsim cov phaj ua tes tsis zoo, thiab cov lus qhia tshwj xeeb, kev txiav, thiab cov riam tsis tau nkag siab zoo. Feem ntau, cov chaw tsim khoom feem ntau tshem tawm cov phaj ua tes thiab siv cov tuam txhab txiav tuag laser. cov laug cam npias ua tes. Txawm li cas los xij, seb qhov loj ntawm cov kab tiv thaiv kev xauv thiab kab siab-qis puas tau teeb tsa raws li qhov hnyav ntawm daim ntawv, seb qhov kev qhia tshwj xeeb ntawm kab riam puas haum rau txhua daim ntawv tuab, seb qhov tob ntawm kab txiav tuag puas tsim nyog, thiab lwm yam txhua yam cuam tshuam rau qhov cuam tshuam ntawm kev tsim cov thawv. Kab txiav tuag yog qhov cim uas raug nias rau ntawm qhov chaw ntawm daim ntawv los ntawm lub siab ntawm daim ntawv thiab lub tshuab. Yog tias kab txiav tuag tob dhau, cov fibers ntawm daim ntawv yuav raug deformed vim yog lub siab; yog tias kab txiav tuag tob dhau, cov fibers ntawv yuav tsis nkag mus tag nrho. Vim yog qhov elasticity ntawm daim ntawv nws tus kheej, thaum ob sab ntawm lub thawv ntawv raug tsim thiab tais rov qab, qhov kev txiav ntawm ntug ntawm qhov qhib yuav nthuav dav mus rau sab nraud, ua rau muaj qhov tshwm sim uas qhov qhib dav dhau.lub thawv tswm ciab

3. Yuav kom ntseeg tau tias muaj qhov zoo ntawm kev ntxig, ntxiv rau kev xaiv cov kab ntxig thiab riam hlau zoo, yuav tsum tau them sai sai rau kev kho qhov siab ntawm lub tshuab, kev xaiv cov roj hmab thiab kev teeb tsa tus qauv. Feem ntau, cov chaw tsim khoom luam ntawv siv cov ntawv nplaum los kho qhov tob ntawm cov kab creasing. Peb paub tias cov ntawv cardboard feem ntau xoob hauv cov qauv thiab tsis tawv txaus, yog li qhov tshwm sim yog tias cov kab ntxig tsis puv thiab ruaj khov. Yog tias cov khoom siv pwm hauv qab tuaj yeem siv tau, cov kab ntxig yuav puv dua.

4. Nrhiav txoj hauv kev los ntawm hom ntawv imposition yog txoj hauv kev tseem ceeb los daws qhov kev taw qhia ntawm daim ntawv fiber. Niaj hnub no, qhov kev taw qhia fiber ntawm daim ntawv hauv khw yog qhov ruaj khov, feem ntau ntawm lawv siv qhov kev taw qhia ntev ua qhov kev taw qhia fiber, thiab kev luam ntawv ntawm lub thawv xim yog luam tawm qee qhov nyiaj ntawm daim ntawv folio, peb-npaug lossis plaub-npaug. Qhov xwm txheej dav dav yog Nyob rau ntawm lub hauv paus ntawm tsis cuam tshuam rau qhov zoo ntawm cov khoom, ntau daim ntawv koj muab tso ua ke, qhov zoo dua, vim tias qhov no tuaj yeem txo qhov pov tseg ntawm cov ntaub ntawv thiab yog li txo tus nqi. Txawm li cas los xij, yog tias koj xav txog tus nqi khoom siv thiab tsis quav ntsej txog qhov kev taw qhia fiber, lub thawv tsim yuav ncav cuag Tsawg dua li qhov kev thov ntawm cov neeg siv khoom. Feem ntau, nws yog qhov zoo tagnrho uas qhov kev taw qhia fiber ntawm daim ntawv yog perpendicular rau qhov kev taw qhia ntawm qhov qhib.

Hauv kev xaus lus, tsuav yog peb ua tib zoo mloog cov ntsiab lus ntawm qhov no thaum lub sijhawm tsim khoom thiab sim zam nws ntawm cov ntawv thiab thev naus laus zis, qhov teeb meem tuaj yeem daws tau yooj yim.
