Tsawg-siab tsawg-kub kub khiav tshuab yog dav siv rau cov cua sov-sensitive yas molding, xws li PVC mos roj hmab, TPE elastomers, foamed PP cov ntaub ntawv thiab biodegradable PLA resin. Cov ntaub ntawv no degrade sai heev nyob rau hauv qhov kub thiab txias, yuav tsum tau kub khiav systems kom ruaj khov tsis tshua muaj - kub tsis tu ncua kub, thiab pa siab - kub K / J thermocouples muaj teeb liab lag thiab qis - rhiab heev tsis muaj peev xwm ua tau raws li qis -kub precise tswj xav tau, {8} siab siab {9} Thermocouple sib piv schemes.
Hom E thermocouples yog thawj qhov siab - kev xaiv rhiab heev rau qis - kub kub- cov yas rhiab heev. Hom E alloy xov hlau muaj cov nickel-chromium zoo thiab tooj liab- cov ntaub ntawv tsis zoo, nrog rau cov khoom siv hluav taws xob muaj peev xwm ua tau ze li ob npaug ntawm K- hom kev sojntsuam hauv qab qhov kub ntawm 400℃. Lub teeb liab rhiab heev ua rau cov tswj qhov kub thiab txias tuaj yeem ntes me me 0.5℃qhov kub thiab txias hloov tam sim ntawd, paub txog ultra-PID fais fab kev hloov kho kom tsis txhob muaj cua sov hauv zos ntawm cov cua sov-sensitive melts. Qhov kub ua hauj lwm tas mus li ntawm Hom E npog 0-800 degree, zoo kawg nkaus txuam nrog 180-320℃molding qhov rais ntawm TPE, PLA thiab mos PVC, zoo tiv thaiv cov khoom yellowing, foaming thiab molecular saw degradation los ntawm me me kub overshoots.
Rau ultra-tsawg kub foamed khoom pwm hauv qab 220 degree, optimized J-hom thermocouples nrog luv- voj voog calibration tseem raug nqi- zoo. Txij li thaum qhov kub ua hauj lwm nyob deb tshaj J- hom 750℃oxidation pib, hlau hlau drift yuav txo tau zoo heev. Cov neeg tsim khoom xaiv qis- impurity siab-purity J- hom hlau hlau, nrog rau lub Hoobkas calibration kam rau ua tswj nyob rau hauv ± 2 degree, haum rau huab hwm coj ntau lawm ntawm tsawg- nqi foamed ntim khoom. Txawm li cas los xij, J- hom kev sojntsuam tsis tuaj yeem siv yog tias cov txheej txheem muaj qee zaus qhov kub thiab txias siab tshaj 700 degree, kom tsis txhob muaj oxidation sai.
Kev ua kom zoo ntawm cov qauv rau qis-kub kub khiav thermocouples tsom rau ultra- qis thermal huab hwm coj ceev teb tsim. Nyias-phab ntsa 0.5–1.0mm MI sheath probes tau txais kev pom zoo los txo qhov nqus cua sov; qhov ntsuas qhov ntsuas tuaj yeem pub rov qab qhov ntsuas kub me me ntawm qhov qis- kub yaj hauv 0.2 vib nas this, tshem tawm cov teeb meem overheating lag ntawm cov txheej txheem tuab tuab. Lub caij nplooj ntoos hlav bayonet hu rau cov qauv yog qhov yuav tsum tau ua, raws li qis- kub pwm hlau muaj thermal expansion me me, thiab cov xovxwm ruaj khov- haum cov kev sojntsuam yooj yim ua rau huab cua sib txawv ua rau kev nyeem ntawv tsis sib txawv, ua rau cov maub los overheating them.
Cov khoom siv rwb thaiv tsev tshwj xeeb sib piv rau cov cua sov- qhov chaw tsim khoom yas rhiab heev. Biodegradable PLA thiab foamed plastics tso tawm me me ntawm cov organic acid volatile roj thaum lub sij hawm yaj, yog li kev sojntsuam sheaths hloov mus rau 316L stainless hlau nrog daim iav polishing los tiv thaiv tsis muaj zog acid corrosion. Sab nrauv cable rwb thaiv tsev siv PTFE es tsis txhob iav fiber ntau braid; iav fiber ntau absorbs organic volatile tshuaj thiab muaj hnub nyoog sai nyob rau hauv ntev -lub sij hawm qis- kub kub hluav taws xob, thaum PTFE tuav ruaj khov rwb thaiv tsev yam tsis muaj tshuaj tiv thaiv nrog cov khoom decomposition gas.
Kev sib koom ua ke ntawm tus maub los yog qhov tseem ceeb tom qab kev teeb tsa qis - kub siab rau thermocouples. Thaum siv hom E probes, hloov kho cov thermocouple hom teeb tsa ntawm txhua tus tswj channel los ntawm lub neej ntawd K-hom rau E- hom; Kev teeb tsa tsis sib haum yuav ua rau muaj kev sib txawv ntawm kev nyeem ntawv ntau tshaj 10 degree, ua rau muaj kev puas tsuaj loj heev. Txo cov PID cua sov kev sib koom ua ke kom txo qis zog tso zis amplitude, sib piv lub siab -rhiab heev teeb liab yam ntxwv ntawm hom E thermocouples kom tsis txhob kub overshoot.
Tsawg-siab qis-kub kub khiav molding cia siab rau siab- rhiab heev qis-kub thermocouples los xauv cov khoom nqaim ua qhov kub thiab txias, txo cov khoom siv hluav taws xob tsawg- rhiab heev thiab biodegradable raw cov ntaub ntawv thiab txhim kho cov khoom tiav tiav ntawm cov khoom siv roj hmab thiab ua npuas ncauj.
