Cov ntaub ntawv tseem ceeb rau kev tsim cov ntawv tsis muaj cov ntawv suav nrog cov ntawv tsim tawm carbonless thiab SMA resin (styrene-maleic anhydride copolymer), ntawm lwm cov ntaub ntawv tshuaj.
Cov txheej txheem tsim khoom yooj yim feem ntau suav nrog cov khoom siv raw khoom, sib tov, txheej, ziab, calendering, thiab txiav. Txhawm rau txhim kho kev ua haujlwm tau zoo, niaj hnub tsim khoom feem ntau siv cov txheej txheem txuas txuas ntxiv, uas suav nrog kev sib dhos, sib dhos, sib dhos, daim ntawv txiav, ntawv nias thiab xa tawm, padding, stacking thiab conveying, vibrating coj-nce, ntug trimming, txhuam sib cais, gluing thiab lamination, thiab ntim. Qhov no txo qis ib nrab- cov khoom tiav tiav thiab kev ua haujlwm poob.
Txhawm rau txhim kho kev tsim khoom, kev ruaj ntseg, thiab cov khoom zoo, kev lag luam tau siv ntau yam kev txhim kho rau cov khoom siv ntau lawm. Cov patents muaj xws li kev txhim kho rau cov tshuab ziab khaub ncaws, cov khoom siv siab rau cov ntawv txiav, thiab cov txheej txheem stacking. Kev txhim kho qhov cub tsim kom ntseeg tau tias cov ntawv tsis muaj cov pa roj carbon monoxide tseem nyob hauv cov txheej txheem ziab, lav cov khoom zoo. Daim ntawv txiav lub siab rau cov menyuam sib dhos nta ib qho kev ncua deb ntawm lub hauv paus tsim, yooj yim rau kev teeb tsa ntawm cov menyuam sib txawv. Cov txheej txheem stacking siv cov khoom uas tuaj yeem ua raws cov ntawv hauv ntau cov lus qhia, ua kom cov npoo zoo nkauj thiab zoo ib yam thaum cov ntawv luam tawm, uas yooj yim rau ntim.
