Cov txheej txheem sib xyaw ua ke tau muab faib ua cov txheej txheem sib txawv, cov khoom siv cov khoom tseem ceeb hauv cov roj hmab hauv cov nplais thiab cov khoom siv sib xyaw ua ke phaj ntawm cov tuab tuab tom qab xovxwm. Cov txheej txheem noo noo yog 18 ~ 20% Thaum cov ntsiab lus noo noo, thiab ua tiav cov ntsiab lus noo ntawm cov txheej txheem tseem ceeb Yuav tsum muaj qhov qis dua li ntawm cov txheej txheem saum npoo av los tswj cov dej sib txawv 1 . 2 ~ 1 .}} {}. (4) (4) (4) tsim nyog cov xovxwm sijhawm .} Yog lub sijhawm luv luv, thiab lub dav hlau zoo tshaj plaws { soj ntsuam . Txawm li cas los xij, nws yuav ua rau muaj cov khoom siv kub ntawm lub ntsej muag. Cov khoom siv tshuab kub heev yog hais tias nws muaj cov khoom siv roj hmab, tsis yog nws siv cov roj hmab ua haujlwm, thiab tsis txhob tso qoob loo Kaw cov pwm kub thiab ua lub luag haujlwm ntawm gelatinization, tab sis nws tau ua los ntawm kev ua kom sov, thiab nws tau siv cov khoom siv kub ua lag luam moulding cov khoom siv cov khoom siv Sab hauv kho kom zoo nkauj thiab cov khoom txhawb nqa thiab lwm yam khoom lag luam, cov nplaum yog cov khoom siv tawm, thiab cov ntawv luam tawm lossis cov ntawv luam tawm ntawm ib zaug. Ib qho ntxiv, tseem muaj cov txheej txheem moulding nyob rau hauv uas cov particeboard uas tau ua, lossis moulded slab uas tsis tau siv tus qauv los ua tus qauv nyem.
