Cov txheej txheem thiab cov ntaub ntawv yuav tsum tau rau cov khoom siv ntawm cov ntawv pov tseg

Cov tshav kub seering kev ua tau zoo thiab kev luam ntawv hloov kho ntawm cov ntawv pov tseg cov ntaub ntawv yuav tsum tau hais tias inks, cov kuab tshuaj, thiab cov tshuab dustness yuav tsum tsim nyog rau cov khob khob. Qhov zoo ntawm cov ntawv khob yog qhov tshwm sim ntawm kev sib xyaw ua ke khob luam ntawv cov txheej txheem, ntawv khob khob luam ntawv ntawv, thiab ntawv khob luam ntawv num luam ntawv.
Feem ntau nyob rau hauv kev luam ntawv ntawm cov khob ntawv, flexographic dej-raws li cov hnab yas ua kom zoo, acid thiab alkali ua kom zoo, acid thiab alkali poob thiab lwm yam tshwm sim txo. Tsis tas li ntawd, cov xaim ntawm tus cwj mem yuav tsum ua raws li kev ua zaub mov huv si thiab cov qauv ntim cov zaub mov kom huv.
Cov hnyav ntawm tus kua mis siv hauv kev luam ntawv cov khob pov tseg tsis tuaj yeem yog PE zaj duab xis, thiab tsis tuaj yeem muaj dej cuam tshuam kom tsis txhob curling daim ntawv khob. Tus nqi ntawm residual cov kuab tshuaj tom qab kev luam ntawv yuav tsum muaj me me kom tiv thaiv kev sib txhuam los ntawm cov ntawv luam tawm. Yog tias cov kuab tshuaj yog thov rau lub foob, nws tseem yuav ua rau lub foob tsis muaj nruj, cov nplaum tsis zoo, thiab txawm tias qhov ncauj yob yuav tshwm sim.

Tom qab cov ntawv khob ua tiav, cov tshuab ziab khaub ncaws ua haujlwm yuav tsis txhob siab dhau, thiab thaum qhov kub ntawm lub hauv paus yuav ua rau muaj kev sib tw sib xyaw ua ke, ua rau muaj kev kub ceev. Yog tias tus txheeb ze cov av noo hauv chav ua haujlwm yog dhau lawm, nws tseem yuav ua rau cov ntawv pov tseg khob kom curl. Tom qab luam ntawv, cov yeeb yaj kiab yob yuav lo nruab nrab ntawm sab saud thiab qis dua qhov ntsuas kub thiab kev yoog raws li cov ntaub ntawv pov tseg.

Ntawv khob luam tawm cov khoom siv cov khoom siv ntau lawm: cov xeev cov pob txha ntaub pov tseg "tsis tuaj yeem ntxiv cov ntxhiab tsw phem". Cov ntaub ntawv pov tseg cov khob tau muab faib ua cov khob dej txias thiab khob dej kub raws li lawv siv. Thaum siv tsis tau lossis siv tsis tau, nws yuav cuam tshuam kev noj qab haus huv ntawm lub cev. Cov khoom siv raw rau lub coated waterproof txheej nyob rau hauv daim ntawv pov tseg lub khob yog polyethylene. Cov khoom siv hluav taws xob hauv tsev yog ua los ntawm cov khoom siv rov ua dua tshiab, uas yuav tsim muaj ntau cov tshuaj tiv thaiv ntau yam ua thiab ntau lawm. Daim ntawv khob yog coated nrog ib txheej ntawm polyethylene dej thaiv zaj duab xis nyob sab hauv kom ua tiav cov nyhuv dej.

Qhov chaw ntawm lub khob dej txias yuav tsum tau impregnated nrog ciab lossis waxed kom ua tiav cov nyhuv ntawm waterproofing. Thaum cov dej kub tshaj li 62 degrees, qhov ruaj khov ntawm cov ciab tsis muaj zog thiab lub khob khob muag. Cov tshuaj uas tuaj yeem ua rau mob cancer tau noj los ntawm lub cev nrog dej. Qhov saum npoo ntawm lub khob dej kub tau dhau los nrog lub ntsej muag polyethylene tshwj xeeb uas tau pom zoo los ntawm lub xeev, uas muaj cov cua sov tsis kam thiab tsis muaj kuab lom.
Tsis tas li ntawd, tseem muaj cov qauv rau cov tuab thiab permeability ntawm cov khob pov tseg, thiab ob sab ntawm cov khob tsis tuaj yeem permes lossis permeable, thiab daim ntawv yuav tsum tsis txhob mos.
Yog xav paub ntxiv txog cov ntawv pov tseg cov khob thiab cov khoom ntawm cov ntawv pov tseg khob, thov mus rau lub websin biyin biyin biyin bazaar mus kawm cov khoom lag luam txhua hnub kom pom ntau yam khoom hauv kev nthuav dav.
