Kev sib piv ntawm ntxaib-Screw Extruders thiab Ib Leeg-Screw Extruders: Yam ntxwv

Cov qauv ntawm lub thoob ntawm ntxaib- ntsia hlau extruders zoo ib yam li ntawm ib qho - ntsia hlau extruders, kuj tau muab faib ua ib lub thoob thiab segmented chim. Intermeshing counter-rotating thiab conical extruders feem ntau siv ib lub thoob; tsuas yog ob peb lub loj extruders siv segmented chim los pab txhawb machining thiab txuag ntawm cov khoom kim heev alloy steel. Co-rotating extruders feem ntau siv segmented chim. Lub segmented chim tau muab faib ua ob peb ntu ntawm qhov sib npaug. Qee ntu muaj cov chaw noj mov, qee qhov muaj qhov chaw nres nkoj, thiab qee qhov muaj cov chaw nres nkoj ntxiv.

Cov seem no txuas nrog cov ntsia hlau los ua ib qho kev sib koom ua ke - ntsia hlau chim.

Cov yam ntxwv ntawm ntxaib-Screw Extruders piv rau ib leeg-Screw Extruders:
1. Kev pub mis yooj yim. Vim tias cov khoom siv thauj khoom raws li txoj cai hloov pauv zoo, nws tuaj yeem ua cov ntaub ntawv uas muaj cov viscosity siab lossis qis heev, nrog rau cov khoom siv zoo li cov khoom siv, cov khoom khov, thiab cov khoom siv granular.
2. Lub sijhawm nyob luv luv ntawm cov khoom siv hauv extruder, nrog rau lub sijhawm nyob hauv nqaim faib. Yog li ntawd, lub extruder yog tsim nyog rau kev ua cov cua sov- cov ntaub ntawv rhiab heev.
3. Kev ua haujlwm tau zoo heev. Qhov no yog vim tus kheej - ntxuav cov nyhuv ntawm intermeshing ntxaib screws, uas tso cai rau kom txaus renewal nto ntawm cov khoom nyob rau hauv lub venting seem.
4. Zoo heev sib xyaw thiab melting nyhuv.
5. Tsawg zog siv. Kev siv hluav taws xob yog kwv yees li 30% qis dua li ntawm ib zaug - ntsia hlau extruders, muab ntxaib- ntsia hlau yas extruders ib qho txiaj ntsig zoo hauv kev txuag hluav taws xob thiab kev txo qis.

Hauv co-rotating ntxaib- ntsia hlau extruders, vim hais tias cov lus qhia ceev ntawm cov ntsia hlau ya davhlau thiab grooves nyob rau hauv lub intermeshing cheeb tsam yog opposite, tus txheeb ze ceev yog siab, uas ua rau ib tug considerably siab shear tus nqi. Qhov no tuaj yeem tshem tawm cov ntaub ntawv khaws tseg uas ua raws li cov ntsia hlau, muab kev ua haujlwm zoo ntawm tus kheej - ntxuav, yog li ua rau lub sijhawm nyob ntawm cov khoom siv luv luv thiab tiv thaiv kev puas tsuaj hauv zos thiab kev puas tsuaj.
