Yuav ua li cas Thermocouples Optimize Melt Viscosity rau Perfect Flow thiab Part Quality

Melt viscosity yog ib qho tseem ceeb tshaj qhov sib txawv uas cuam tshuam rau kev coj tus cwj pwm, kev tshuav nyiaj li cas, ib feem ntawm kev ncaj ncees, thiab qhov chaw zoo hauv kev txhaj tshuaj molding - thiab viscosity yog tswj ncaj qha los ntawm qhov kub thiab txias. Thermocouples muab qhov tseeb, tiag tiag -lub sijhawm, cov ntaub ntawv ntsuas kub ruaj khov uas xav tau los tswj kom zoo ib yam, rov ua dua cov viscosity thoob plaws txhua lub voj voog ntau lawm. Txawm tias qhov hloov pauv me me (tsawg li 1 degree) tuaj yeem hloov pauv cov viscosity ntawm cov resin viscosity, tshwj xeeb tshaj yog rau cov cua sov-sensitive, siab-kev ua tau zoo, lossis nqaim- ua- qhov rai polymers. Yog tias qhov kub thiab txias qis dhau, yaj viscosity nce ntxiv, ua rau muaj kev txhaj tshuaj siab, txhaj tshuaj luv luv, cov kab txuas, kev ntxhov siab sab hauv, thiab qhov seem tsis ruaj khov. Yog tias qhov kub thiab txias heev, yaj viscosity poob deb dhau, ua rau flash, drool, stringing, splay, hlawv cov cim, cov khoom degradation, thiab warpage. Siab -cov thermocouples precision tswj qhov kub thiab txias ntawm qhov sib txawv ntawm ± 0.5 degree, kom ntseeg tau tias yaj viscosity nyob ruaj khov, kwv yees tau, thiab zoo tagnrho rau kev sau. Hauv ntau-kab kab noj hniav pwm, kev tswj qhov kub thiab txias los ntawm calibrated, siab -cov thermocouples tsis sib xws tuaj yeem lav qhov viscosity zoo tib yam hauv txhua lub nozzle, ntsuas qhov ntws thiab ua kom muaj qhov zoo sib xws thoob plaws txhua qhov kab noj hniav. Fast- teb cov thermocouples pom txawm tias qhov ntsuas kub me me hloov tam sim ntawd, tso cai rau tus maub los kho lub zog cua sov tam sim ua ntej viscosity hloov mus rau qhov zoo. Yog tsis muaj qhov tseeb, txhim khu kev qha qhov kub thiab txias, yaj viscosity tsis tuaj yeem tswj tau-txawm tias muaj cov tshuab txhaj tshuaj molding siab tshaj plaws thiab cov tshuab kub khiav. Ntau cov txheej txheem teeb meem tau liam rau ntawm cov khoom zoo lossis pwm tsim ua tau los ntawm kev ua haujlwm tsis zoo ntawm thermocouple. Rau cov txheej txheem engineers, optimizing melt viscosity pib nrog optimizing kub tswj, uas nyob ntawm tag nrho ntawm siab-zoo, zoo- tuav thermocouples. Raws li cov ntaub ntawv tshawb fawb tau nce qib thiab cov resins tau dhau los ua tshwj xeeb, qhov kev xav tau rau kev tswj cov viscosity tsuas yog loj tuaj, ua rau cov thermocouple kev ua tau zoo dua qub.
