Hauv kev tsim khoom niaj hnub, cov khoom yas tau dhau los ua ib feem tseem ceeb. Ntawm lawv, cov ntawv yas, raws li cov khoom siv yas, muaj ntau yam kev siv hauv kev tsim kho, rooj tog zaum, ntim khoom thiab lwm yam. Kab lus no yuav qhia koj txog cov txheej txheem tsim khoom thiab thev naus laus zis ntawm cov ntawv yas, thiab tsom mus rau PE daim ntawv manufacturers.
Kev tsim cov ntawv yas feem ntau suav nrog kev npaj cov khoom siv raw, extrusion molding, txias curing thiab txiav. Ua ntej tshaj plaws, cov tuam txhab tsim khoom yuav tsum tau npaj cov ntaub ntawv raw, PE (polyethylene) yog ib qho ntawm cov khoom siv yas uas nquag siv. Tom qab ntawd, PE raw khoom yog rhuab mus rau lub xeev molten los ntawm extruder, thiab ces extruded los ntawm pwm. Extrusion molding yog extrusion ntawm melted yas los ntawm lub siab ntawm pwm los ua ib daim ntawv yas txuas ntxiv. Hauv cov txheej txheem no, cov khoom siv ntxiv xws li xim thiab nplaim hluav taws tuaj yeem raug ntxiv raws li xav tau los txhim kho kev ua tau zoo thiab cov khoom zoo.
Kev ua kom txias thiab kho yog qhov txuas tseem ceeb hauv kev tsim cov ntawv yas. Cov ntawv yas extruded yuav tsum tau txias kom kho thiaj li tau txais cov khoom zoo ntawm lub cev thiab tshuaj lom neeg. Cov ntawv yas sib txawv yuav xav tau lub sijhawm sib txawv thiab kev tswj qhov kub thiab txias thaum lub caij txias kom ntseeg tau tias cov khoom kawg muaj qhov zoo thiab ruaj khov.
Thaum kawg, cov ntawv yas yuav tsum tau mus dhau cov txheej txheem tom ntej xws li txiav kom tau raws li qhov xav tau ntawm cov neeg siv khoom sib txawv. Kev txiav tuaj yeem ua tiav los ntawm kev txiav tshuab, laser txiav, thiab lwm yam, kom tau txais qhov xav tau loj thiab cov duab.
Raws li cov chaw tsim khoom PE, nws yog ib qho tseem ceeb kom nkag siab txog cov txheej txheem tsim khoom thiab thev naus laus zis ntawm cov ntawv yas los txhim kho cov khoom zoo thiab kev ua haujlwm zoo. Los ntawm kev nruam nruam thiab kev qhia txog cov khoom siv ntau lawm, PE daim ntawv tuam ntxhab tuaj yeem muab cov khoom zoo, muaj ntau hom ntawv yas kom tau raws li kev xav tau ntawm kev lag luam.
