Distributive mixing kis cov khoom los ntawm cov yaj; dispersive mixing lov agglomerates los yog txo qhov loj ntawm ib theem dispersed. Ib tug ntxaib-ntsia hlau configuration feem ntau xav tau ob qho tib si, tab sis qhov sib npaug yuav tsum ua raws li qhov tsis xws luag thiab kev tsim es tsis yog qhov kev nyiam rau siab dua shear. Ua ntej txheeb xyuas qhov teeb meem, tom qab ntawd sib piv kev sib xyaw kom zoo nyob rau hauv cov kab thermal thiab mechanical txwv.

Xaiv ib lub conical ntxaib ntsia hlau extruder los yog ib tug parallel ntxaib ntsia hlau extruder los ntawm PVC formulation, yuav tsum tau ntau lawm qhov rais thiab tshuab configuration, tsis yog daim ntawv lo geometry ib leeg. Sib piv cov txheej txheem sib npaug, tom qab ntawd xyuas cov khoom tso tawm, cov khoom zoo, kev siv hluav taws xob thiab kev sib xyaw ua ke. Rau ib txoj kab uas twb muaj lawm, txiav txim siab seb koj puas xav tau cov khoom hloov pauv lossis lub tshuab sib txawv ua ntej thov cov lus hais.

Extruder ntsia hlau pitch yog qhov sib nrug ntawm axial ntawm cov davhlau uas nyob ib sab; txhuas yog qhov axial ua ntej ntawm tib lub helix los ntawm ib qho kev ua tiav. Lawv sib npaug ntawm ib qho kev pib ib ntus, tab sis tsis yog ntawm txhua tus ntsia hlau. Xaiv ib qho kev hloov pauv los ntawm nws cov txiaj ntsig ntawm kev pub mis, melting thiab kev xa khoom siab, es tsis yog xav tias qhov dav dav yuav lav tau cov txiaj ntsig zoo dua.

Extruder ntsia hlau channel qhov tob piav qhia qhov chaw nruab nrab ntawm cov ntsia hlau hauv paus thiab ib qho kev siv sab nrauv. Ib qho kev sib sib zog nqus channel muab ntau qhov chaw, tab sis nws tsis cia li xa tawm ntau qhov zoo tawm tsam kev tuag. Xaiv qhov profile los ntawm nws txoj haujlwm pub mis, melting thiab twj tso kua mis, nrog rau qhov tseeb qhov ntev, cov khoom siv thiab cov khoom sib txuam.

Ib qho ntsia hlau extruder L / D piv yog qhov ntev ua haujlwm tau muab faib los ntawm nominal ntsia hlau taub. Xaiv nws los ntawm qhov chaw uas xav tau rau kev pub mis, melting, sib tov, venting thiab siab txoj kev loj hlob, tsis yog los ntawm kev xav tias ib tug ntev ntsia hlau xa tawm ntau lawm. Paub meej qhov ntsuas datums thiab tshuab compatibility ua ntej sib piv cov lus.

Extrusion ntsia hlau compression piv piav qhia txog qhov txo qis hauv channel ntim los ntawm kev pub mis rau metering; rau cov pa screws nrog tib cov hlau lead nyob rau hauv ob qho tib si ib cheeb tsam, nws yog feem ntau qhia raws li pub channel qhov tob muab faib los ntawm metering channel qhov tob. Xaiv nws nrog qhov tseeb qhov tob, qhov hloov pauv ntev, cov khoom noj khoom haus thiab lub thoob tsim, tsis yog los ntawm lub npe polymer ib leeg. Qhov sib piv ntau dua tsis tau txais cov ntsia hlau zoo dua.
