Cov teeb meem loj tshaj plaws hauv kev ntim thiab luam ntawv tau ua rau cov neeg plagu ntev ntev. Cov teeb meem mas yog cov concentrated rau 1 tus lej migration; 2 number case film daj; 3 cov ntawv luam dawb dawb; 4 rov qab adhesion thiab adhesion; 5 kev sib thooj thiab sib zog; 6 number case film floating dawb; Pinhole thiab ntsws qhov; 8 hloov tsis muaj cwj; 9 tom tsos nqaij daim tawv (feem ntau hu ua ntoo khaub lig) thiab fading; 10 gloss sib txawv (whitening). Cov teeb meem kev siv tshuab luam ntawv tau dhau los ua ib qho kev txhaum nyob rau hauv ntau lawm.
1. Raug xim (feem ntau hu ua ntoo khaub lig). Nyob rau hauv cov txheej txheem luam ntawv, thaum thawj zaug los thib ob dhau ntawm cov xim luam ntawv, cov xim ntawm cov kabmob zaj duab xis ntawm cov ntawv luam tawm dhau los yuav pom tau tias cov ntawv luam tawm ntawm cov ntawv luam tawm yog qhov muag heev thiab txawm ntsws. Qhov tshwm sim no yog hu ua prelude to bite color. Thaum lub xauv kua xuv tooj muaj cov xim hnyav tom qab luam ntawv (tom qab luam ntawv), nws yuav txav tau mus rau yav dhau los ntawm tus yeeb yaj kiab zaj duab xis thiab raug tom, yog li ua yuam kev rau hauv cov tom qab zaj duab xis, uas tuaj yeem ua rau tom qab ntim rau hauv cov mob hnyav. Cov ntawv luam tawm zaj duab xis yog sib xyaw nrog mottling (dyeing). Lub ntsiab yog vim tias muaj cov khoom xyaw soluble (resins los yog cov kuab tshuaj) hauv luam ntawv number case.
Thaum luam ntawv rau cov phaw twj, nws yog ib qhov tsim nyog siv qhov hnoos qej. Tsis txhob siv lub zog hnyav txhawm rau kho cov tawv nqaij ntawm tus xauv npo los sis ua kom ceev tau cov ntawv luam tawm kom luv dua zaum ob lossis zaum thib peb. Siv ib qho sib xyaw xyaw los kho qhov rov ua dua ntawm tus cwj mem ua ntej luam ntawv. Dej cev) siv los txiav txim seb qhov hnyav npaum licas.
2. Ua tsis zoo (gluten). Feem ntau ntawm qhov kev ua no tsis tuaj yeem tshwm sim nyob rau hauv cov luam ntawm cov tshuab luam yeeb qhuav heev. Ib cov yeeb yuj thaij duab uas muaj yeeb yaj kiab dub tshwm tuaj thaum lub sijhawm evaporation ceev ceev tom qab muaj kev kub ceev. Qhov no tshwm sim yog tej zaum ib ntus, tab sis feem ntau ntev ntev. Qhov no yog vim hais tias qhov txias txias uas nyob ib sab ntawm lub ziab khaub noom ntim zaj duab xis yog cua tshuab lossis cua txias rau cov dej nplej, uas yog, dej ntub dej (vapor) xa rov qab mus rau cov duab zaj duab xis kom haum. Yog hais tias qhov hnyav los yog cov xim hauv cov kua xaum dej muaj dej, nws tseem yuav ua rau cov neeg pluag tsis zoo hauv daim duab luam. Uas yog hais tias, qhov ntau dua qhov volatility ntawm qhov hnyav, qhov ntau dua qhov ntsuam ntawm cov duab thaij duab (xim dawb) ntawm lub hnab ntim ntawv luam los ua neeg pluag hauv gloss.
Cov kev ntsuas yuav tsum yog: kho qhov hnyav siv los ntim cov ntawv luam tawm; ua kom lub cev kub hnyav (xws li cyclohexanone, diol, propylene glycol ether, butanol, thiab lwm yam) kom txo tau cov tshuaj hnoos uas tau qhuav sai. Hauv kev ntim thiab luam ntawv, tswj qhov kev cob qhia. Qhov ntsuas kub nruab nrab ntawm thaj chaw (huab cua) yog qis dua 65%, tshwj xeeb tshaj yog thaum lub caij ntuj nag nyob rau hauv cov chaw ntug hiav txwv thiab cov hnub los nag nyob rau sab qaum teb.
