Yuav Ua Li Cas Xaiv Cov Thermocouples rau Cov Txheej Txheem Kub Kub Ua Haujlwm Siab -Gloss Appearance Resins?

High-gloss zoo li resins, xws li kho qhov muag- qib PC, PMMA, thiab ABS, yog siv nyob rau hauv cov ntawv thov xws li tsheb sab hauv trim, cov neeg siv khoom siv hluav taws xob vaj tsev, thiab cov lo ntsiab muag kho qhov muag. Cov ntaub ntawv no xav tau flawless nto tiav nrog tsis pom cov cim ntws, cov kab txuas, lossis rooj vag blush. Thermocouples ua lub luag haujlwm tseem ceeb hauv kev ua tiav qhov no los ntawm kev tswj xyuas qhov kub thiab txias. Thawj qhov txheej txheem xaiv yog ultra- qhov kub thiab txias raug. High-gloss resins muaj qhov ua haujlwm nqaim heev-feem ntau tsuas yog 2-3℃. Lub thermocouple drift ntawm 1℃tuaj yeem ua rau pom qhov tsis xws luag. Chav kawm 1 thermocouples nrog kev ua siab ntev ntawm ± 0.5℃yog qhov tseem ceeb. Qhov thib ob kev ntsuas yog ceev teb. High-gloss daim ntawv thov feem ntau siv cov kev txhaj tshuaj nrawm kom khov rau saum npoo sai, tiv thaiv qhov tsis xws luag. Lub thermocouple yuav tsum teb nyob rau hauv milliseconds kom ntes cov kub hloov ceev thaum txhaj tshuaj. Grounded junctions nrog nyias probes (0.5-0.8 mm) muab cov lus teb ceev tshaj plaws. Qhov thib peb yam ntxwv yog tsawg thermal mass. Lub thermocouple nws tus kheej yuav tsum tsis txhob ua raws li lub dab dej kub, vim qhov no tuaj yeem ua rau cov cua txias hauv zos uas cuam tshuam rau cov yaj lub viscosity thiab ntws. Ib qho kev sojntsuam me me nrog qhov loj me me yuav tsum tau ua. Qhov thib plaub yog qhov kev tso kawm. Lub thermocouple yuav tsum tau muab tso rau ntawm lub rooj vag, qhov chaw zoo tshaj plaws cuam tshuam. Nws yuav tsum tau muab tso rau hauv 2-3 hli ntawm lub rooj vag, tab sis nyob rau hauv qhov chaw uas tsis cuam tshuam cov yaj ntws. Qhov thib tsib txheej txheem yog cov ntaub ntawv sheath. High-gloss resins rhiab heev rau kev sib kis. Lub sheath yuav tsum tau ua los ntawm cov khoom uas tsis hnov ​​​​mob nrog cov resin los yog tso tawm tej yam khoom . 316 stainless hlau nrog ib tug du, polished tiav yog ib yam. Qhov thib rau kev ntsuas yog tsis kam rau shear cua sov. High-gloss resins feem ntau txhaj tshuaj ntawm kev kub ceev, ua kom muaj cua sov tseem ceeb uas tuaj yeem ua rau hauv cheeb tsam overheating. Lub thermocouple yuav tsum tiv taus qhov kub ntawm lub sijhawm tsis muaj drifting. Qhov thib xya txheej txheem yog lub cable thiab connector. Lub cable yuav tsum yoog raws thiab muaj cov rwb thaiv tsev uas tsis tshua muaj hluav taws xob, vim tias cov volatiles tuaj yeem condense ntawm pwm nto thiab ua rau muaj qhov tsis xws luag. PTFE-insulated cables nyiam dua. Lub yim txheej txheem yog qhov calibration. Lub thermocouple yuav tsum tau ntsuas ntawm qhov kev ua haujlwm kub (piv txwv li, 280 degree) kom ntseeg tau qhov tseeb tshaj plaws ntawm qhov ntawd. Daim ntawv pov thawj calibration yuav tsum suav nrog qhov sib txawv ntawm qhov kub ntawd. Los ntawm kev xaiv cov thermocouples uas ua tau raws li cov txheej txheem nruj no, cov molders ntawm qhov chaw siab gloss tuaj yeem ua tiav qhov flawless nto tiav uas cov neeg siv khoom xav tau, txo cov seem thiab rov ua haujlwm dua. Kev nqis peev hauv hwm thermocouples yog kev ncaj ncees los ntawm tus nqi siab ntawm cov khoom tsim thiab tus nqi ntawm ib qho kev tsis lees paub.
