Kev Ua Lag Luam Tus Nqi Siv Twin -Screw Extruders

Kev lag luam tus nqi ntawm kev siv ntxaib- ntsia hlau extruders tsis yog kho tab sis txiav txim siab los ntawm kev sib xyaw ua ke, suav nrog hom, qauv, qhov xwm txheej, qib hnav ntawm cov khoom tseem ceeb, thiab cov khoom lag luam thiab kev thov. Feem ntau, cov khoom siv los ntawm cov khoom lag luam thoob ntiaj teb (xws li Koberlon thiab Lister) khaws nws cov nqi zoo dua, nrog rau tus nqi txog li 15% lossis ntau dua; Lub tshuab qhov loj me (piv txwv li, 65-mm tshuab) thiab cov xyoo siv tiag tiag cuam tshuam tus nqi. Lub qhov dej- khaws cia, nyob ze- tshuab tshiab tuaj yeem nqa tau 50%–60% ntawm tus nqi ntawm chav tsev tshiab, thaum cov khoom siv qub lossis hnyav hnyav tuaj yeem khaws cov nqi seem xwb. Tsis tas li ntawd, cov khoom muag muag raws li ib feem ntawm kev ua tiav cov kab ntau lawm, kev kho dua tshiab, thiab txhawb nqa los ntawm kev lees paub muaj txiaj ntsig ntau dua li cov khoom muag sib cais. Lub caij no, tus nqi-kev ua tau zoo ntawm cov khoom siv hauv tsev xa tawm tau ua rau nws muaj kev sib tw hauv kev lag luam thoob ntiaj teb. Yog li ntawd, kev ntsuam xyuas nws cov nqi lag luam yuav tsum xav txog qhov kev ua haujlwm tiag tiag, kev hloov pauv tam sim no, thiab tus neeg yuav khoom qhov kev ntsuas ntawm kev ua tau zoo piv rau kev pheej hmoo.
