High-Viscosity Plastic Processing: Thermocouple Sensitive Temperature Control rau High-Power Thermal Compensation
High -Viscosity modified plastics thiab tshwj xeeb engineering plastics muaj cov yam ntxwv ntawm qhov kub thiab txias, thiab qhov kub hloov pauv me me yuav cuam tshuam ncaj qha rau yaj fluidity thiab cov khoom molding zoo. Hauv kev tsim khoom tiag tiag, kev hloov pauv thaum tshav kub kub tshwm sim los ntawm cov khoom siv viscosity hloov tau yooj yim ua rau cov nyiaj kub tsis txaus, ua rau lub xeev tsis khov. Tus qauv qis- lub tshuab hluav taws xob muaj hluav taws xob muaj cov lus teb qeeb thiab tsis muaj peev xwm them nyiaj tsis txaus, tsis tuaj yeem hloov kho rau qhov kev xav tau ntawm cov cua sov hloov pauv. High-lub zog cam khwb cia tooj liab rhaub koom tes nrog siab -rhiab heev thermocouple systems kom paub tseeb-lub sij hawm dynamic thermal them nyiaj rau siab - viscosity khoom ua.
High-Kev ua cov yas viscosity muaj cov yam ntxwv thermal load sib txawv. Nyob rau hauv cov txheej txheem extrusion thiab txhaj tshuaj, cov khoom shear tshav kub thiab tiv thaiv tshav kub hloov dynamically nrog ntau lawm ceev thiab cov khoom viscosity. Cov khoom siv hluav taws xob uas muaj lub zog qis qis tsis tuaj yeem kho cov zis hluav taws xob hauv lub sijhawm tiag tiag raws li kev hloov pauv. Thaum tshav kub kub poob sai sai, lub zog cua sov tsis txaus los tswj qhov kub thiab txias, ua rau yaj viscosity nce thiab tsis muaj dej txaus. Thermocouple pa calibration hom tsis tuaj yeem ntes dynamic load hloov, ua rau ncua kev hloov pauv thiab cov txheej txheem lag.
High- lub zog cam khwb cia tooj liab tso cua sov muaj lub zog hloov kho lub zog tshwj xeeb thiab cov thermal teb ceev ceev, uas tuaj yeem tiv thaiv cov cua kub hloov pauv hauv siab - cov khoom siv viscosity. Lub siab kub flux tso zis muaj peev xwm instantly ntxiv kub poob los ntawm instantaneous tshav kub poob, tuav ruaj khov kub. Tsawg thermal hysteresis cov yam ntxwv ua kom lub zog hloov pauv hloov pauv thiab hloov pauv kub, tsis muaj kev tswj hwm lag luam thiab qhov ntsuas kub sib txawv.
Ua ke nrog siab -rhiab heev thermocouple dynamic induction thev naus laus zis, siab - lub tshuab hluav taws xob cua sov paub txog cov khoom siv thermal. Thermocouple sensors ntes hloov pauv qhov kub thiab txias tshwm sim los ntawm kev hloov pauv viscosity hauv lub sijhawm tiag tiag, thiab kev tswj hwm lub zog dynamically kho lub tshuab hluav taws xob tso zis hluav taws xob raws li qhov xav tau. Qhov kaw - voj dynamic them nyiaj hom ua tiav daws qhov kub tsis ruaj khov los ntawm qhov sib txawv ntawm cov cua sov thiab ua kom cov dej ntws zoo sib xws ntawm cov khoom muaj viscosity siab.
Siab -cov ntaub ntawv viscosity ua cov ntaub ntawv kuaj xyuas kom pom tseeb tus nqi zoo. Hauv kev hloov kho PA thiab siab - viscosity PC ua, cov txheej txheem cua sov ua kom kub hloov pauv ntawm 1.6℃thiab cov khoom tsis raug ntawm 2.8%. Siab - lub zog cam khwb cia tooj liab cua sov tshuab nrog cov khoom siv hluav taws xob zoo thermocouple tswj kev hloov pauv tsis pub dhau 0.35℃thiab txo qis tus nqi mus rau 0.4%, txhim kho cov txiaj ntsig ntau lawm.
Precision ua tiav ntawm siab -viscosity tshwj xeeb plastics yuav tsum tau dynamic thermal them nyiaj system. Kev cob qhia cov khoom siv thermal cov yam ntxwv kev soj ntsuam thiab kho cov thermocouple dynamic nyiaj them schemes tuaj yeem hloov mus rau qhov sib txawv ntawm cov khoom xav tau thiab ruaj khov siab -precision molding zoo ntawm tshwj xeeb engineering yas.
