Kev tsim khoom thiab siv lub khob khob tshuab yog ua raws li txoj cai tiv thaiv ib puag ncig hauv tebchaws. Hloov cov khob yas pov tseg nrog cov khob ntawv txo cov pa phem dawb. Qhov yooj yim, huv si thiab pheej yig ntawm cov khob ntawv yog cov yuam sij los hloov lwm yam khoom siv kom dav hauv khw. Cov khob ntawv muab faib ua khob dej txias thiab khob dej kub raws li lawv siv. Cov khoom ntawm lub khob ntawv yuav tsum tsis yog tsuas yog ua tau raws li qhov xav tau ntawm nws cov ntim kev ua tau zoo, tab sis kuj ua tau raws li nws cov kev hloov pauv luam ntawv. Ntxiv mus, ntawm ntau yam ntawm cov tshuab luam ntawv, cov xwm txheej rau kev sib khi ntawm cov ntawv khob yuav tsum tau ua tiav.
Cov ntawv khob cov khoom tsim los ntawm lub khob khob tshuab yog tsim los ntawm kev luam ntawv ncaj qha, txiav tuag, sib sau, thiab txau cov khoom noj khoom haus rau saum npoo ntawm daim ntawv khob hauv paus ntawv. Cov txheej txheem ntau lawm ntawm lub khob haus dej kub yog los txheej cov ntawv khob hauv paus ntawv rau hauv daim ntawv khob ntawv, luam ntawv, txiav tuag thiab molding. Lub hauv paus ntawv ntawm lub khob ntawv yog tsim los ntawm cov nroj tsuag fibers. Cov txheej txheem ntau lawm feem ntau siv cov ntoo fibers xws li cov ntoo coniferous thiab hardwood kom dhau los ntawm lub rooj tsavxwm pulp tom qab pulping, refining, ntxiv chemical auxiliary cov ntaub ntawv, tshuaj ntsuam xyuas, ntawv tshuab luam ntawv, thiab lwm yam. Cov ntawv khob ntawm lub khob ntawv tshuab yog tsim los ntawm cov ntawv khob. puag ntawv thiab yas resin hais extruded. Polyethylene resin (PE) feem ntau yog siv los ua cov yas yas. Daim ntawv khob hauv paus ntawv yog coated nrog ib sab PE zaj duab xis lossis ob sab PE zaj duab xis los ua ib sab PE ntawv khob ntawv lossis ob sab PE ntawv khob ntawv.
PE nws tus kheej tsis muaj tshuaj lom, tsis muaj ntxhiab thiab tsis qab; txhim khu kev qha huv si; ruaj khov tshuaj ua haujlwm; balanced lub cev thiab txhua yam khoom, zoo txias kuj; dej tsis kam, noo noo tsis kam, qee yam oxygen barrier, roj kuj; zoo heev molding kev ua tau zoo thiab zoo tshav kub sealing kev ua tau zoo. Polyethylene muaj cov zis loj, qhov chaw yooj yim thiab tus nqi qis, tab sis nws tsis haum rau kev ua noj kub kub. Yog tias lub khob ntawv muaj qhov tshwj xeeb yuav tsum tau ua, cov yas resin nrog cov kev ua tau zoo yuav tsum raug xaiv thaum lamination.
