Cov txheej txheem parameters ntawmyas extrudercov cav tov tuaj yeem muab faib ua ob hom: inherent parameters thiab adjustable parameters.
Cov yam ntxwv tsis xws luag yog txiav txim los ntawm tus qauv, uas sawv cev rau nws lub cev qauv, ntau lawm hom, thiab daim ntawv thov ntau yam.Inherent tsis yog ib tug series ntawm coj tsis tau formulated los ntawm ntau lawm designer ntawm lub extrusion unit raws li tus yam ntxwv ntawm tus qauv.Cov kev txwv no qhia cov yam ntxwv, daim ntawv thov, thiab lub peev xwm tsim khoom ntawm chav tsev, thiab tseem muab lub hauv paus rau kev tsim cov hom phiaj tsim khoom thiab cov txheej txheem kho tau.
Adjustable parameters yog ib co kev tswj tsis tau teem los ntawm ntau lawm kab neeg ua hauj lwm nyob rau hauv lub extrusion unit thiab cov khoom siv tswj raws li lub hom phiaj ntau lawm.Cov kev ntsuas no txiav txim siab tus yam ntxwv thiab qhov zoo ntawm cov khoom lag luam thiab seb cov khoom siv puas tuaj yeem ua haujlwm tsis tu ncua thiab ruaj khov.Lawv yog tus yuam sij rau kev tsim khoom yas extrusion.Adjustable parameters tsis muaj tus qauv ntsuas qhov tseeb tab sis yog txheeb ze.Qee lub sij hawm tus nqi ntau yog muab rau qee qhov tsis muaj tus lej, uas yuav tsum tau txiav txim siab raws li qhov tseeb ntawm kev tsim khoom.
Nov yog daim ntawv teev cov ntsiab lus:

Dab tsi yog qhov haujlwm ntawm lubyas extruder?
Covyas extrudermuaj cov haujlwm tseem ceeb hauv qab no:
1. Nws tuaj yeem muab cov khoom siv yas zoo li qub thaum cov khoom siv yas extruded rau hauv cov khoom yas.
2. Nws siv tau tuaj yeem ua kom ntseeg tau tias cov khoom siv raw khoom sib xyaw ua ke thiab ua tiav cov yas hauv qhov kub thiab txias uas yuav tsum tau ua los ntawm cov txheej txheem.
3. Nws tuaj yeem muab cov khoom siv molten nrog cov dej ntws zoo sib xws thiab kev ruaj khov siab rau kev tsim tuag kom cov yas extrusion ntau lawm tuaj yeem ua tau zoo thiab du.
Dab tsi yog cov txheej txheem ntws ntawmyas extruder?
Extrusion molding, tseem hu ua extrusion molding los yog extrusion molding, feem ntau yog hais txog ib txoj kev molding nyob rau hauv uas rhuab molten polymer cov ntaub ntawv raug yuam kom tsim nruam profiles nrog ib tug tas mus li ntu ntu los ntawm kev tuag nyob rau hauv kev txhawb zog siab nrog kev pab los ntawm extrusion. kev ua ntawm cov ntsia hlau los yog plunger.Cov txheej txheem extrusion feem ntau suav nrog kev pub mis, melting thiab plasticizing, extrusion, shaping, thiab txias.Cov txheej txheem extrusion tuaj yeem muab faib ua ob theem: thawj theem yog ua kom cov yas khoom yas (piv txwv li tig nws mus rau hauv cov kua dej khov) thiab ua kom nws dhau los ntawm kev tuag nrog cov duab tshwj xeeb hauv siab los ua ib qho txuas ntxiv nrog cov seem zoo sib xws thiab tuag. ;Qhov thib ob theem yog siv cov txheej txheem tsim nyog los ua kom cov extruded continuum poob nws cov yas hauv lub xeev thiab ua cov khoom kom tau txais cov khoom tsim nyog.
Dab tsi yog lub ntsiab adjustable parameter ntawmyas extruder?
Nov yog qee qhov kev hloov pauv tseem ceeb.
1. Ceev ceev
Cov ntsia hlau ceev yuav tsum tau kho nyob rau hauv lub ntsiab cav tswj ntawm lub pelletextruder.Cov ntsia hlau ceev ncaj qha cuam tshuam rau tus nqi ntawm cov khoom siv extruder, nrog rau cov cua sov tsim los ntawm kev sib txhuam ntawm cov ntaub ntawv thiab cov ntaub ntawv fluidity.
2. chim thiab lub taub hau kub
Cov khoom yuav dhau los ua cov tshuaj molten ntawm qhov kub thiab txias.Cov tshuaj viscosity yog inversely proportional rau qhov kub thiab txias, yog li lub peev xwm extrusion ntawm extruder yuav cuam tshuam los ntawm kev hloov ntawm cov khoom kub.
3. Qhov kub thiab txias ntawm lub tshuab ua kom sov
Kev teeb tsa hom thiab hom txias yuav txawv raws li cov khoom sib txawv.Muaj ntau hom khoom siv, tab sis qhov kub thiab txias yuav tsum tau tswj.Qhov nruab nrab cua txias feem ntau yog cua, dej, lossis lwm yam kua.
4. Traction ceev
Lub linear ceev ntawm cov menyuam traction yuav tsum phim qhov ceev extrusion.Lub traction ceev kuj txiav txim siab qhov cross-section loj thiab txias nyhuv ntawm cov khoom.Traction kuj cuam tshuam rau longitudinal tensile, mechanical zog, thiab seem stability ntawm cov khoom.
Txawm hais tias nws yog qhov nyuaj los txiav txim siab qhov hloov pauv tsis tau, lawv tsis yog qhov tsis sib xws, tab sis kuj muaj lub hauv paus theoretical ua raws, thiab muaj qee qhov kev sib raug zoo ntawm cov kev txwv no, uas cuam tshuam rau ib leeg.Tsuav yog peb paub cov txheej txheem ntawm kev kho qhov tsis thiab kev sib raug zoo ntawm cov tsis, peb tuaj yeem ua kom zoo dua cov txheej txheem extrusion ntawmyas extruders.Suzhou Polytime Machinery Co., Ltd. yog ib lub tuam txhab high-tech tshwj xeeb hauv R & D, ntau lawm, muag, thiab kev pabcuam ntawm cov yas extruders, granulators, yas ntxhua khaub ncaws siv tshuab, thiab cov kav dej ntau lawm.Yog tias koj ua haujlwm cuam tshuam txog kev siv cov khoom siv yas lossis cov yas granulation, koj tuaj yeem xav txog peb cov khoom siv high-tech.
