Yas extrusion yog ib qho ntawm cov txheej txheem tsim tau zoo tshaj plaws thiab muaj ntau yam - tab sis nws tsis yog tsis muaj qhov nyuaj. Deg imperfections, dimensional inconsistencies, thiab cov yam ntxwv tsis muaj zog yog tag nrho ib yam nkaus rau hauv extrusion ua hauj lwm. Txhawm rau tswj cov khoom zoo thiab txo cov khoom pov tseg, nws yog ib qho tseem ceeb kom nkag siab txog qhov ua rau tom qab cov yas extrusion tsis xws luag thiab yuav ua li cas los daws lawv kom zoo.
Feem ntau cov yas Extrusion tsis xws luag thiab lawv cov tsos mob
Txawm tias muaj cov ntaub ntawv zoo tshaj plaws thiab thev naus laus zis, cov kab extrusion tuaj yeem tsim cov khoom nrog ntau yam teeb meem. Feem ntau cov tsis xws luag muaj xws li:
Deg roughness: Cov khoom tiav zoo li tsis sib xws los yog npub es tsis txhob du thiab glossy.
Huab cua npuas: me lossis loj voids tshwm nyob rau hauv cov yas profile.
Dimensional instability: Irregularities nyob rau hauv thickness, dav, los yog cov duab ntawm extrudate.
Cracking los yog splitting: pom pob txha tawg ntawm cov khoom, tshwj xeeb tshaj yog thaum lub sij hawm los yog tom qab txias.
Txhua yam ntawm cov teeb meem no cuam tshuam tsis tsuas yog cov tsos, tab sis kuj yog kev ua tau zoo thiab kev siv tau ntawm cov khoom kawg.
Dab tsi ua rau Cov Yas Extrusion Defects?
To taub lub hauv paus ua rau yog thawj kauj ruam los daws tej teeb meem. Nov yog qee qhov kev ua txhaum loj tshaj plaws:
1. Kev ua haujlwm tsis ruaj khov
Kev tsis sib haum lossis tsis raug, qhov tuag, lossis qhov txias txias tuaj yeem ua rau cov khoom tsis zoo, degradation, lossis txias tsis sib xws - feem ntau ua rau muaj npuas, tawg, lossis teeb meem saum npoo.
2. Cov khoom nyoos tsis zoo
Moisture nyob rau hauv cov resin los yog paug nrog plua plav thiab txawv teb chaws hais yuav ua rau voids, huab cua npuas, thiab nto imperfections.
3. Tsis txaus Tuag lossis Tooling Tsim
Kev tsim tsis raug tuag ua rau tsis sib xws, qhov chaw tuag, lossis cov ces kaum ntse, txhua yam uas ua rau tawg lossis tsis sib xws.
4. Tsis yog kab nrawm lossis siab
Kev nrawm dhau los yog qeeb dhau txoj kab nrawm tuaj yeem cuam tshuam cov duab ntawm extrudate. Ib yam li ntawd, lub siab tsis ruaj khov ua rau muaj qhov tsis sib xws thiab qhov tsis xws ntawm phab ntsa thickness.
Pov thawj daws kom txo cov yas Extrusion tsis xws luag
Thaum qhov teeb meem raug txheeb xyuas, cov phiaj xwm kev txhim kho tuaj yeem txhim kho cov khoom zoo. Nov yog li cas:
1. Ua kom ruaj khov thiab ua kom zoo tshaj qhov ntsuas kub
Siv cov txheej txheem ntsuas kub siab tshaj plaws los xyuas kom muaj cua sov zoo ib yam thoob plaws hauv lub thoob thiab tuag. Tsis txhob hloov qhov kub thiab txias tam sim ntawd thiab xyuas qhov chaw kub lossis txias.
2. Cov Khoom Siv Ua Ntej Qhuav
Xyuas kom koj cov yas pellets los yog granules tau qhuav kom zoo, tshwj xeeb tshaj yog thaum siv hygroscopic polymers xws li PET lossis Nylon. Lub tshuab ntsuas dej los yog lub tshuab ziab khaub ncaws tuaj yeem tiv thaiv npuas thiab voids.
3. Txheeb xyuas Tuag thiab Tooling Design
Ib tug streamlined tuag nrog optimized flow paths thiab du kev hloov yuav txo tau turbulence thiab tshem tawm ntau yam yas extrusion tsis xws luag. Kev tu thiab tshuaj xyuas cov cuab yeej tsis tu ncua kuj pab tau.
4. Fine-Tune Ceev thiab Siab
Kho extrusion ceev kom sib npaug ntawm cov khoom ntws thiab lub sijhawm txias. Siv cov sensors siab thiab cov lus tawm tswv yim los tswj lub xeev khov kho thoob plaws lub voj voog ntau lawm.
5. Ua raws li kev soj ntsuam zoo hauv kab
Siv lub zeem muag pom thiab qhov ntsuas qhov ntsuas kom pom qhov tsis xws luag thaum ntxov, txo cov khoom pov tseg thiab poob sijhawm.
Lub luag haujlwm ntawm Cov Khoom Siv Hluav Taws Xob Extrusion Siab
Niaj hnub nimno extrusion tshuab yog tsim los txo qhov sib txawv thiab txhim kho qhov sib xws. Cov khoom siv nrog kev tswj hwm ntse, kev ntsuas tsis siv neeg, thiab thaj chaw cua sov zoo tuaj yeem txo qhov tshwm sim ntawm cov yas extrusion tsis xws luag. Kev nqis peev hauv cov tshuab ua haujlwm siab tsis yog tsuas yog txhawb cov khoom lag luam zoo xwb tab sis kuj tseem txhim kho cov khoom lag luam thiab txo cov nqi khiav lag luam hauv lub sijhawm ntev.
Kev Ua Tau Zoo Pib Nrog Txoj Cai Zoo
Hauv cov yas extrusion, kev tiv thaiv qhov tsis xws luag yog qhov ua tau zoo dua li kho lawv tom qab. Los ntawm kev hais txog cov hauv paus hauv paus - xws li kev tuav cov khoom siv, kev tswj qhov kub thiab txias, thiab kev tsim cov cuab yeej - koj tuaj yeem tswj cov khoom lag luam ruaj khov thiab txo qis ntau lawm.
Nrhiav los txhim kho koj cov extrusion kev ua tau zoo nrog txhim khu kev qha, high-precision daws? Sib cuag nrogJWELLniaj hnub no los tshawb nrhiav cov cuab yeej siv thiab kev txawj ntse uas pab koj ua tiav cov txiaj ntsig zoo sib xws.
