Kev tshuaj xyuas qhov ua rau ntawm cov khoom spilling los ntawm lub tshuab nqus tsev chaw nres nkoj ntawm ib tug yeeb nkab Extruder

Thaum lub sij hawm extrusion txheej txheem, roj yuav tsum tau tawm ntawm cov khoom molten. Yog tias cov pa roj no tsis tuaj yeem tso tawm, cov teeb meem xws li qhov pores, npuas, thiab qhov dullness yuav tshwm sim rau ntawm qhov chaw lossis sab hauv ntawm cov khoom, uas tuaj yeem cuam tshuam rau lub cev, txhua yam, tshuaj, thiab hluav taws xob ntawm cov khoom. Kev teeb tsa 1-2 cov chaw nres nkoj tso tawm ntawm qhov chaw noj mov thiab lub taub hau tshuab tuaj yeem tshem tawm cov dej noo thiab lwm yam khoom tsis haum los ntawm cov khoom molten extruded. Tab sis feem ntau muaj qee qhov teeb meem nrog kev qhib lub tog raj kheej steel, thiab qhov teeb meem tshwm sim yog tias cov khoom tawm ntawm qhov chaw nres nkoj tawm. Ib qho me me ntawm cov khoom siv tuaj yeem cuam tshuam rau kev tso tawm ntawm cov khoom tsis haum, uas cuam tshuam rau qhov zoo ntawm cov khoom; Ib qho loj ntawm cov dej ntws tuaj yeem txhaws qhov chaw nres nkoj thiab tseem ua rau muaj kev kaw.
Feem ntau muaj ob qho laj thawj rau cov khoom siv dhau. Ua ntej, qhov tsim tsis tsim nyog ntawm cov ntsia hlau ua rau cov khoom siv rov qab los ntawm qhov chaw nres nkoj tawm; Qhov thib ob yog vim li cas qhov chaw nres nkoj tso tawm yog qhov tsis tsim nyog, ua rau cov ntaub ntawv molten "hang up" thaum dhau los ntawm qhov chaw nres nkoj. Txhawm rau nrhiav qhov laj thawj, ua ntej xyuas seb cov khoom hauv cov ntsia hlau puas ntws rov qab los ntawm qhov chaw nres nkoj tawm. Hauv feem ntau cov pa extruders, koj tuaj yeem pom cov khoom molten tig rau pem hauv ntej hauv cov ntsia hlau. Feem ntau, qhov degree ntawm cov khoom ntim rau hauv cov ntsia hlau zawj tsis tshaj 50 feem pua. Yog tias nws siab tshaj 50 feem pua, nws tsis tsuas yog cuam tshuam rau cov pa tawm, tab sis kuj tuaj yeem ua rau cov khoom xau los ntawm lub qhov hluav taws xob; Thaum nws tsawg dua 50 feem pua, cov ntsia hlau tuaj yeem ua haujlwm ib txwm. Cov khoom dhau los tuaj yeem tshwm sim los ntawm kev tsim tsis raug ntawm cov chaw tso pa tawm lossis cov khoom sib txawv.
Cov xwm txheej cuam tshuam rau cov khoom dhau los thiab kev daws teeb meem
1. Ntsia hlau yam
Lub tshuab tso pa tawm feem ntau siv ntau theem tsim, thiab qhov zoo ntawm qhov tsim no yog qhov chaw nres nkoj tso pa tawm ntawm qhov qub, tiv thaiv cov ntaub ntawv los ntawm ntws tawm. Ib qho extruder nrog ib qho chaw nres nkoj yuav tsum muaj 2-theem ntsia hlau, thiab ib qho extruder nrog ob qhov chaw nres nkoj yuav tsum muaj 3-theem ntsia hlau. Txhua theem muaj qhov seem cua sov, ntu compression, thiab ntsuas ntsuas. Qhov chaw pib ntawm thawj theem yog qhov chaw noj khoom noj hauv huab cua, thiab theem thib ob yog qhov chaw tso pa tawm hauv huab cua, uas yog qhov chaw ntawm qhov chaw tso pa tawm. Muaj ob qhov teeb meem tseem ceeb nrog cov ntsia hlau tsim ntawm lub tshuab nqus tsev extruder: thaum nws mus txog qhov seem, cov khoom yuav tsum tau yaj tag kom tshem tawm cov teeb meem tsis haum; Qhov thib ob, tus nqi pub mis ntawm theem thib ob ntawm cov ntsia hlau yuav tsum muaj ntau dua li ntawm thawj theem ntsia hlau kom ntseeg tau tias cov ntsia hlau zawj thaum pib ntawm theem thib ob tsis puv, uas tuaj yeem tswj lub siab ntawm qhov chaw nres nkoj. Thaum tus nqi pub mis ntawm thawj theem ntsia hlau ntau dua li ntawm qhov thib ob theem ntsia hlau, cov yaj hauv lub extruder yuav muaj kev rov qab. Yuav kom daws tau qhov teeb meem no, nws yog ib qho tsim nyog yuav tsum tau txo qhov pub mis ntawm thawj theem lossis nce tus nqi pub mis ntawm theem thib ob.
2. Cov txheej txheem txheej txheem
Txoj kev yooj yim thiab nrawm los daws qhov teeb meem ntawm cov khoom siv dhau los yog hloov cov txheej txheem txheej txheem. Piv txwv li, txo qhov kub thiab txias, ua kom muaj kev sib txhuam thiab kev ntxhov siab ntawm lub tog raj kheej steel los yog ntsia hlau, thiab ua kom muaj kev sib txhuam los yog viscosity nyob rau saum npoo ntawm lub tog raj kheej steel kom nce cov khoom xa tuaj.
3. Exhaust chaw nres nkoj
Yog tias cov ntsia hlau ntawm qhov chaw nres nkoj tso tawm tsuas yog ib feem puv nkaus thiab qhov chaw nres nkoj tawm tseem tawm cov khoom siv, ces muaj qee qhov teeb meem nrog kev tsim ntawm qhov chaw nres nkoj tso pa. Qhov chaw nres nkoj tso tawm yuav tsum dav dua li cov khoom siv dov kom paub meej tias qhov chaw nres nkoj tsis thaiv los ntawm cov yaj. Nyob rau tib lub sijhawm, qhov qhib ntawm qhov chaw nres nkoj yuav tsum tsis txhob loj dhau, uas tuaj yeem txo qhov chaw nyob ntawm lub sijhawm yaj thiab lub sijhawm nthuav dav ntawm cov khoom ntws.
Tus tswv ntawm cov yeeb nkab extruder chaw tsim tshuaj paus tau sau tseg tias txawm tias lub hau ntswj tso tawm cov khoom siv ncaj qha rau cov txheej txheem extrusion, cov khoom yas, thiab tsim cov ntsia hlau thiab qhov chaw nres nkoj. Yog li ntawd, thaum siv cov pa extruder rau ntau lawm thiab ua, manufacturers yuav tsum muaj cov ncauj lus kom ntxaws cov txheej txheem, resin yam ntxwv, thiab cov cuab yeej ua tau zoo nyob rau hauv thiaj li yuav xyuas kom meej qhov zoo thiab ruaj khov ua hauj lwm ntawm cov pa extruder.
