Cov nyhuv ntawm kev txhaj tshuaj pwm kub ntawm kev txhaj tshuaj molding txheej txheem
I. Kev Taw Qhia
Txhaj pwm kub yog ib qho tseem ceeb cuam tshuam rau kev txhaj tshuaj molding txheej txheem zoo, ntau lawm efficiency thiab tus nqi tswj. Qhov kub ntawm cov pwm yuav cuam tshuam ncaj qha rau molding zoo, ntau lawm efficiency thiab ntau lawm tus nqi ntawm cov yas. Thaum lub sij hawm txhaj tshuaj molding txheej txheem, kev ruaj ntseg thiab kev tswj qhov tseeb ntawm pwm kub muaj qhov cuam tshuam rau kev ua tau zoo thiab qhov zoo ntawm cov khoom. Yog li ntawd, kev nkag siab txog qhov cuam tshuam ntawm pwm kub ntawm cov txheej txheem txhaj tshuaj molding thiab kev tswj xyuas qhov kub thiab txias yog qhov tseem ceeb rau kev txhim kho kev tsim khoom thiab cov khoom zoo.
2. Qhov cuam tshuam ntawm kev txhaj tshuaj pwm kub ntawm kev txhaj tshuaj molding txheej txheem
Yas ntws thiab sib sau
Qhov kub ntawm pwm ncaj qha cuam tshuam rau tus cwj pwm ntws ntawm cov yas. Nyob rau hauv high-temperature pwm, viscosity ntawm cov yas txo thiab fluidity nce, ua rau nws yooj yim mus sau cov pwm kab noj hniav. Txawm li cas los xij, qhov kub pwm ntau dhau yuav ua rau cov yas yaj thiab ntws sai heev, ua rau muaj kev ntxhov siab ntau dhau los yog cov cim ntws hauv ib feem, thiab tej zaum yuav cuam tshuam rau cov khoom siv thiab cov tsos zoo ntawm cov yas vim thermal degradation. Ntawm qhov tsis sib xws, ntawm qhov qis pwm kub, cov yas muaj cov dej tsis zoo, uas yuav ua rau tsis txaus sau lossis ntxhib ntawm qhov chaw.
Cooling thiab shrinkage ntawm qhov chaw
Pwm kub txiav txim siab qhov txias txias thiab shrinkage tus nqi ntawm cov yas hauv pwm kab noj hniav. Qhov ceev ntawm cov cua txias ncaj qha cuam tshuam rau crystallinity ntawm cov yas thiab cov qauv kawg ntawm ib feem. Yog tias qhov txias txias ceev dhau, nws yuav ua rau muaj kev ntxhov siab loj hauv sab hauv, uas yuav ua rau muaj teeb meem zoo xws li warping thiab cracking; thaum yog tias qhov txias txias qeeb dhau, nws tuaj yeem ua rau deformation ntawm ib feem lossis kev ntxhov siab ntau dhau. Pwm kub kuj cuam tshuam rau qhov shrinkage tus nqi ntawm cov yas, uas nyob rau hauv lem cuam tshuam qhov loj thiab tsos ntawm ib feem.
Pwm lub neej thiab kev saib xyuas
Cov pwm kub ntau dhau tuaj yeem ua rau thermal qaug zog thiab hnav ntawm pwm, yog li ua rau lub neej ua haujlwm ntawm pwm. Nyob rau tib lub sijhawm, cov viscosity ntawm cov yas txo qis ntawm qhov kub thiab txias thiab nws yooj yim dua rau kev ua raws li cov pwm kab noj hniav, ua rau qhov nyuaj thiab ua haujlwm ntawm kev ntxuav pwm. Yog tias cov pwm kub qis dhau lawm, cov dej condensation tuaj yeem tshwm sim ntawm cov yas thiab cov pwm, uas ua rau muaj teeb meem xws li dej cim thiab tsis zoo gloss ntawm cov khoom.
3. Kev tswj zoo ntawm kev txhaj tshuaj pwm kub
Preheating thiab ua kom sov
Preheating pwm ua ntej ntau lawm yog ib qho kev ntsuas zoo los xyuas kom meej tias cov pwm kub ruaj khov. Preheating tuaj yeem tshem tawm qhov kub ntawm qhov sib txawv ntawm cov pwm thiab cov yas, tso cai rau cov yas kom zoo dua rau cov pwm kub, thaum txo qhov cuam tshuam ntawm cov dej txias ntawm pwm kub. Rau kev txhaj tshuaj pwm loj los yog complex, rwb thaiv tsev tuaj yeem nqa tawm ntawm cov khoom sib txawv los tswj qhov ruaj khov ntawm pwm kub.
Tswj cov dej txias ntws thiab qhov kub thiab txias
Cov dej txias ntws thiab qhov kub thiab txias yog qhov tseem ceeb cuam tshuam rau pwm kub. Kev kho cov dej txias kom zoo thiab qhov kub thiab txias tuaj yeem tswj cov pwm kub zoo. Thaum lub sij hawm tsim cov txheej txheem, cov dej txias ntws thiab qhov kub thiab txias yuav tsum tau kuaj xyuas tsis tu ncua kom pom tias lawv nyob hauv qhov ntau teev los ntawm cov txheej txheem los xyuas kom meej qhov ruaj khov thiab qhov tseeb ntawm pwm kub.
Kev kho cua sov thiab cua txias
Cov cua sov thiab cua txias yog qhov tseem ceeb ntawm kev tswj cov pwm kub. Kev tshuaj xyuas tsis tu ncua thiab kev saib xyuas cov cua sov thiab cua txias kom ntseeg tau tias lawv cov kev ua haujlwm ib txwm tuaj yeem zam cov pwm kub hloov pauv los ntawm kev ua haujlwm tsis zoo. Nyob rau tib lub sijhawm, rau cov pwm uas siv cov tshuab kub khiav, kev saib xyuas tshwj xeeb yuav tsum tau them rau kev saib xyuas thiab kev saib xyuas ntawm qhov kub khiav.
Npaj cov phiaj xwm tsim khoom kom raug
Kev npaj tsim khoom tsis tsim nyog yuav ua rau muaj kev hloov pauv loj hauv pwm kub. Hauv kev tsim cov khoom siv ntau yam thiab ntau xim, lub hauv paus ntsiab lus ntawm "tib xim thiab tib qhov kub thiab txias" yuav tsum ua raws li kom tsis txhob muaj pwm kub hloov pauv los ntawm kev hloov xim. Nyob rau tib lub sijhawm, kev tsim khoom tas mus li yog qhov tsim nyog rau kev tswj xyuas qhov ruaj khov ntawm pwm kub.
