Dab tsi yog cov txheej txheem ntawm cov extruder hauv cov txheej txheem ntau lawm, tam sim no kuv yuav coj txhua tus los qhia cov ntsiab lus ntawm qib no.
Kev sib xyaw, kev sib xyaw, kev zawm ntsej muag Ib qho kev sib xyaw yog zoo li cov nqaij sib tov: cov khoom txig rau cov khoom noj yog cov khoom txig rau hauv cov khoom siv, ntau dua lossis tsawg dua raug tshav kub, thiab tom qab ntawd tusyees sib xyaw, nyem raws li lub qhov taub, thiab tom qab ntawd txiav los ntawm rab riam txiav (ntawv). Ob qhov siab siab extruder screws hloov lub kinetic zog tsim nyog rau kneading rau cov ntaub ntawv raw, yog li cov txuas ntxiv extruder qee zaum hu ua" extruder ntsia hlau agitator" ;.
Rau cov ntawv thov tau yooj yim, yog tias cov txheej txheem ntau lawm tsuas yog suav nrog ib lossis ob qho txheej txheem thev naus laus zis, ib qho ntsia hlau txuas nkaus xwb tuaj yeem siv los ua cov haujlwm tseeb ntawm kev ua, sib tw thiab yaj. Rau cov khoom siv ntau lawm thiab tsim cov ntawv thov, suav nrog peb-theem thiab txheej txheem txheej txheem loj, xws li kev sib xyaw, homogenization, sab nraud diffusion, thiab cov xim sib ntxiv lossis cov xim sib txuas ua ke, cov ntxaib ib leeg-ntsia hlau extruders yuav tsum tau tig nyob rau tib qho kev coj.
Piv txwv li, yog tias cov khoom siv pab xaiv tau ntxiv rau ib kawg ntawm qhov extruder, nws yog qhov ua tau kom tau tsim cov khoom noj tshiab, cov khoom noj txom ncauj, thiab cov khoom noj tshais lwm yam tom kawg. Los ntawm hloov daim ntawv qhia zais cia ntawm cov ntaub ntawv pabcuam, nws yog qhov ua tau kom tau tsim cov tsiaj ua khoom noj rau miv thiab dev. Yog tias qhov ntsuas kub thiab shear kev ntxhov siab tau nce (tom qab cov khoom xyaw raug txiav thiab cais tawm, lub caij ua haujlwm yog tom qab ntawd tso cai rau muab coj los tso ua ke), cov ntses pub ntses tuaj yeem tsim, hauv lwm txoj lus, lub neej khaws cia ntawm cov khoom lag luam muaj txiaj ntsig, xws li ceg , tuaj yeem ua kom muaj zog.
