Dab tsi yog daim ntawv thov ntawm cov khoom ntsuas kub hauv cov khoom siv polymer?

Nyob rau hauv kev lag luam ntawm polymer manufacturing, kub yog ib qho tseem ceeb nam uas yuav ua tau los yog wreck lub qab ntxiag thiab tag nrho cov kev ua tau zoo ntawm cov khoom kawg. Qhov ntsuas kub qhov ntsuas ntsuas ua haujlwm tseem ceeb hauv kev ua kom paub tseeb tias aa ntaus kev tsim khoom. Duab cov chaw tsim khoom niaj hnub niaj hnub polymer, ib qho chaw ua si uas muaj teeb meem tshuaj lom neeg tshwm sim. Qhov ntsuas kub qhov ntsuas kub yog hom ntawm tus neeg saib xyuas uas ntsiag to, tsis tu ncua taug qab thiab tswj qhov ntsuas kub kom tau txais txiaj ntsig zoo tshaj plaws.
Thermocouples tuaj yeem ua tau zoo heev hauv kev tsim khoom polymer. Raws li cov khoom tsis ua tiav tau ua tiav thiab hloov mus rau hauv polymers, kev tswj qhov kub thiab txias yog qhov tseem ceeb. Piv txwv li, nyob rau hauv extrusion txheej txheem, nyob rau hauv uas molten polymer yog pressed los ntawm ib tug tuag los tsim ntau yam duab, qhov kub ntawm lub polymer soften yuav tsum tau ceev faj tswj. Thermocouples yuav nyob ntawm tej yam tshwj xeeb ib sab ntawm lub extruder chim thiab tuag kom ntsuas qhov kub. Qhov no tso cai rau cov neeg ua haujlwm hloov kho cov cua sov thiab cua txias kom ua tau raws li qhov nyiam kub ntau yam. Los ntawm kev ua kom qhov kub thiab txias tsis tu ncua, cov khoom extruded tuaj yeem muaj qhov chaw nyob thiab qhov ntev.
Hauv cov tshuaj tiv thaiv polymerization, qhov kub thiab txias kuj tseem ua haujlwm tseem ceeb. Cov qauv sib txawv ntawm cov polymers xav tau qhov ntsuas kub tshwj xeeb rau cov lus teb kom tshwm sim tau zoo. Thermocouples tuaj yeem muab tso rau hauv cov hlab ntsha teb los ntsuas qhov ntsuas kub tag nrho los ntawm txoj kev polymerization. Qhov no pab txhawb kev ua kom zoo rau cov xwm txheej teb thiab ua kom paub tseeb tias cov polymer yog fashioned nrog cov yam ntxwv nyiam. Piv txwv li, yog tias qhov kub thiab txias tsuas yog dhau los lossis qis dhau, nws tuaj yeem cuam tshuam rau qhov hnyav molecular, crystallinity, thiab ntau qhov chaw nyob ntawm polymer.
Ntxiv nrog rau kev tswj cov txheej txheem tsim khoom, ntsuas qhov ntsuas qhov ntsuas kub yog qhov tseem ceeb rau kev tswj kom zoo. Los ntawm kev taug qab qhov ntsuas kub ntawm cov qib tshwj xeeb ntawm kev tsim khoom, txhua qhov sib txawv yuav raug kuaj pom thaum ntxov, thiab kev hloov kho yuav raug coj mus. Piv txwv li, yog hais tias qhov kub ntawm lub polymer soften tsuas yog dhau heev lawm, nws muaj peev xwm ua rau degradation los yog discoloration ntawm polymer. Thermocouples tuaj yeem muab qhov ntsuas kub ntawm lub sijhawm tiag tiag, suav nrog kev hloov pauv luv luv kom txuag tau koj cov teeb meem zoo nkauj.
Thaum lub chaw nres tsheb thiab kev thauj mus los ntawm cov polymers, kev tswj qhov kub thiab txias kuj tseem ceeb heev. Qee cov polymers yog touchy rau qhov kub thiab txias thiab tej zaum yuav degrade los yog nkig yog tias uncovered mus rau qhov kub thiab txias. Cov cuab yeej ntsuas qhov ntsuas kub yuav raug siv los tshuaj xyuas qhov ntsuas kub ntawm thaj chaw nres tsheb thiab thauj cov thawv ntim kom paub tseeb tias cov polymers tau khaws cia hauv qhov kub ntau yam.
Qhov ntsuas kub qhov ntsuas hauv cov khoom siv polymer yog qhov tseem ceeb rau kev nyab xeeb. Qhov kub thiab txias tuaj yeem ua rau muaj kev phom sij rau lub plawv, thiab qee qhov xwm txheej, cov polymers tseem tuaj yeem tso cov pa phem yog tias kub dhau. Los ntawm kev soj ntsuam qhov ntsuas kub tas li, cov txheej txheem ceev faj thaum ntxov yuav raug qhib yog tias qhov kub thiab txias txoj kev pheej hmoo siab. Hauv kev xaus, qhov ntsuas qhov ntsuas kub, xws li thermocouples, muaj ntau yam pob khoom hauv kev tsim khoom polymer. Los ntawm kev tswj hwm txoj kev tsim khoom kom paub tseeb tias qab ntxiag thiab kev nyab xeeb, qhov ntsuas kub yog qhov tseem ceeb ntawm kev tsim cov khoom siv polymer.
