Dab tsi tag nrho cov txheej txheem ntawm kev extruder hauv cov txheej txheem ntau lawm? Tam sim no cia' s coj txhua tus neeg los txiav txim siab cov ntsiab lus ntawm qib no. Kev sib xyaw, kev sib xyaw, kev sib nraus Ib qho kev sib xyaw yog zoo li cov nqaij sib tov: cov khoom noj nyoos rau cov khoom noj, muab nkag rau hauv cov cuab yeej siv, ntau dua lossis tsawg dua rau qhov kub kub, ces tusyees sib xyaw, nyem raws li lub qhov ntawm lub raj raj cov khoom, thiab tom qab ntawd txiav los ntawm kev txiav riam (Khoom Loj). Ob qhov siab siab qhov txuas extruder screws xa cov kev tig tau lub zog tsim nyog rau kneading rau cov ntaub ntawv raw. Yog li ntawd, cov txuas nruam txuas ntxiv 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 theem, ib qho ntsia hlau txuas nkaus xwb tuaj yeem siv los ua cov haujlwm ntawm kev ua, sib tw thiab yaj. Rau cov khoom siv ntau lawm thiab tsim cov ntawv thov, suav nrog peb-theem thiab loj-txheej txheem thev naus laus zis, xws li sib xyaw, homogenization, sib kis, thiab cov xim sib ntxiv lossis cov xim sib txuas ua ke cov txheej txheem thev naus laus zis, nws yog qhov yuav tsum tau tig lub ntxaib ib leeg-ntsia hlau extruder tib qho kev. Cov.
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 kub thiab shear kev ntxhov siab tau nce (tom qab lub caij ua haujlwm txiav thiab sib cais, lub caij ua si yog tso cai rau remix), nws muaj peev xwm tsim cov ntses pub ntses, hauv lwm cov lus los ua kom lub neej khaws cia ntawm cov khoom lag luam muaj txiaj ntsig, xws li ceg. Buhler' s nruam extruder twb tau siv los pellet reed nyom los tsim paj potted. Rau tus tsiaj plaub ya ri tau zoo los ntawm cov plastics plam, Buhler' s txuas ntxiv nruam siv siv Midream thiab nqes dej tau-theem polycondensation kev tsis haum.
