Taw qhia Cov Khoom Paub Ntxiv Khoom Ua Ntoo-yas Tawv

Cov ntaub ntawv ntoo-yas muaj lawv cov kev tiv thaiv ib puag ncig thiab lub zog txuag hluav taws xob, yog li dab tsi ntau lawm ntawm cov khoom ntoo-yas ntsa? Hauv qab no yog cov kev qhia ntawm cov ntoo-yas chaw tsim hluav taws xob:

Ua ntej txhua yam, ntoo-yas phab ntsa yuav tsum tau txias thiab zoo li tam sim ntawd tom qab kev tuag ntawm lub taub hau extruder kom tiv thaiv deformation, kev nyuaj siab lossis cuam tshuam ntawm cov profile hauv nws tus kheej kev sib tsoo. Tom qab ntawd, feem ntau, kev kho qhov chaw thiab txias yuav tsum tau nqa tawm tib lub sijhawm, extruding daim ntawv thiab daim ntawv, thiab qee zaum dhau los ntawm kev tuav ob lub siab yob ib ce. Tsis tas li ntawd, rau cov khoom ntoo-yas nrog cov ntoo loj hauv cov ntawv lossis tuab dua, cov cua txias tuaj yeem siv; rau ecological ntoo khoom nrog cov ntoo fiber ntau cov ntsiab lus lossis qhov hnyav tuab, dej txias yuav tsum siv.
