1. Daim ntawv thov ntawm cov nplaum rau hauv thav duab sib dhos - kev sib txuas ntawm cov duab los qhia / lim khoom / hlau
Cov lim no ntau dua yog pom nyob rau hauv daim duab 1 ca lim, ntxiv rau lub thawv lim thiab lwm yam. Cardboard, lim cov ntaub ntawv, hlau, vim hais tias feem ntau ntawm cov ntaub ntawv no yog ib co saj zawg zog cov ntaub ntawv, yog li ntawd ib co tsoos kev twb kev txuas txoj kev yog ntau nyuaj rau ua, thiab adhesives ua rau nws yooj yim. Nyob rau hauv feem ntau ntawm cov txheej txheem no, emulsion adhesives yog siv, thiab ntawm chav kawm, kub yaj adhesives kuj siv tau yog hais tias tus txheej txheem tso cai. Txoj kev kho ntawm emulsion nplaum feem ntau yog dej-raws li hom evaporation, vim hais tias cov evaporation ntawm cov dej cuam tshuam los ntawm qhov kub thiab txias, yog li los ntawm cov txheej txheem ntawm ib puag ncig ib puag ncig yuav tsum tau siab. Qee cov tuam txhab lag luam kuj siv cov kuab tshuaj raws li cov nplaum nplaum, uas yooj yim rau kev ua tiav ntawm cov txheej txheem. Txawm li cas los xij, kev ntxiv dag zog rau ib puag ncig cov cai tau txhawb kev hloov pauv ntawm cov nplaum rau cov kuab tshuaj tsis muaj kuab lom, thiab cov qauv ntawm kev lag luam nplaum tuaj yeem raug sau tseg hauv cov lus hauv qab no: kev tso tawm qis, kev ua haujlwm siab.
2. Daim ntawv thov ntawm cov nplaum hauv lub hnab lim
Nyob rau hauv lub hnab lim, kev sib khi ntawm qhov sib txawv ntawm qhov sib txawv thiab kev sib txuas ib ntus ua ntej cov ntsia hlau sib dhos tag nrho muaj kev cuam tshuam cov haujlwm tshwj xeeb ntawm cov nplaum. Kev sib khi ntawm qhov sib txawv ntawm qhov sib txawv feem ntau yog ua los ntawm cov nplaum nplaum kub, thaum lub sij hawm ib ntus kev sib txuas ua ntej ntsia hlau sib dhos feem ntau yog ua los ntawm dej-raws li evaporative nplaum los yog ib puag ncig hnyav-raws li nplaum nplaum.
3. Daim ntawv thov ntawm cov nplaum rau ntawm huab cua lim - pleating
Thaum siv cov ntawv lim cov ntaub ntawv, txhawm rau kom muaj peev xwm ua kom muaj plua plav txaus (kev pabcuam lub neej) thiab tsis tshua muaj kev tiv thaiv, qhov chaw ntawm daim ntawv lim hauv lub lim yuav tsum yog kaum tawm lub sij hawm ntawm lub tshuab cua ntawm lub lim, vim li no, cov ntaub ntawv lim cov ntaub ntawv folded. yuav tsum tau sib cais nyob rau hauv ib txoj kev. Hauv qhov no, adhesives ib zaug ntxiv qhia lawv cov kev txawj ntse. Qhov ruaj khov pleating nrug nrog kub yaj nplaum tuaj yeem ua kom ntseeg tau tias muaj qee qhov kev ncua deb ntawm txhua txheej ntawm cov ntawv lim, thiab cov nplaum kub yaj tuaj yeem hloov kho raws li qhov xav tau ntawm ntau yam qauv xws li siab thiab qis tsis kam thiab nplaim taws me me, yog li ntawd cov lim qhia tau hais tias muaj ntau yam kev ua tau zoo, feem ntau yog siv rau hauv kev tsim cov lim pleating, tsis muaj kev faib lim thiab qee cov lim tsev me me. Nws muaj cov yam ntxwv ntawm tasteless, zoo kub tsis kam, ceev ceev adhesion, tsis-stick tes, zoo tee, thiab yuav tsis absorbed los ntawm lim ntawv.
