Hauv kev ntsuas cov txheej txheem, ib qho ntawm cov lus teb tseem ceeb rau cov khoom ntsuas corrosive yog siv cov khoom siv tsim nyog uas tiv taus corrosion rau cov cuab yeej ntub dej, sensing diaphragm lossis nws cov txheej, lub thawv hluav taws xob lossis lwm yam khoom thiab fittings xav tau.
PTFE:
PTFE (Polytetrafluoroethylene) yog ib hom yas engineering uas mos, sib dua thiab tsis muaj kev sib txhuam uas muaj kev tiv thaiv xeb zoo heev. Nws yog ib qho kev daws teeb meem pheej yig rau cov xwm txheej hnyav hauv kev ua tshuaj lom neeg thiab roj & roj av. Txawm li cas los xij, nws yuav tsum paub tias PTFE tsis siv tau rau qhov kub thiab txias tshaj 260 ℃, qhov nyuaj qis ua rau nws tsis haum rau xov lossis diaphragm khoom.
Tantalum:
Tantalum yog ib hom hlau uas tiv taus xeb heev thiab muaj peev xwm tiv taus ntau yam tshuaj lom neeg, ua rau nws yog ib qho kev xaiv zoo rau kev ntsuas cov khoom siv diaphragm rau cov xov xwm corrosive heev. Txawm li cas los xij, cov hlau no kim heev thiab tsis tshua siv ntau npaum li lwm cov ntaub ntawv. Hauv cov txheej txheem tshuaj lom neeg uas tswj cov kua qaub uas muaj zog heev, lub ntsuas siab uas muaj tantalum sensing diaphragm yog qhov tsim nyog rau txoj haujlwm kom ua tiav qib siab tshaj plaws ntawm kev tiv taus xeb.
Cov Khoom Siv Ua Los Ntawm Av nplaum:
Cov khoom siv ceramic yog ib yam khoom siv inorganic uas tsis yog hlau uas tsis muaj zog thiab tiv taus kub thiab xeb zoo heev. Cov khoom siv piezoresistive/capacitance sensors nrog zirconia lossis alumina ceramic membrane feem ntau siv rau hauv cov tshuaj lom neeg, tshuaj, thiab khoom noj thiab dej haus. Nws tseem ceeb heev uas yuav tsum nco ntsoov tias vim yog cov khoom tsis yog hlau, ceramic yog brittle yog li cov khoom siv ceramic tsis haum rau kev cuam tshuam siab, thermal shock thiab kev siv siab thiab xav tau kev saib xyuas ntxiv thaum tuav.
Hastelloy Alloy:
Hastelloy yog ib qho ntawm cov hlau nickel-based alloys, uas C-276 qhia tau tias muaj kev tiv thaiv corrosion zoo tshaj plaws thiab feem ntau raug xaiv los ua cov khoom siv rau cov twj paj nruag diaphragm thiab lwm yam khoom ntub dej tiv thaiv cov xov xwm corrosive. C-276 alloy yog siv rau hauv feem ntau qhov chaw lag luam uas muaj cov tshuaj lom neeg hnyav thiab lwm yam khoom siv yuav ua tsis tiav.
Hlau tsis xeb 316L:
Feem ntau cov hlau tsis xeb uas siv rau lub diaphragm sensing yog qib 316L. SS316L muaj kev tiv thaiv corrosion nruab nrab, cov khoom siv kho tshuab zoo thiab tus nqi pheej yig. Lub plhaub hlau tsis xeb ntawm lub tsev tsis ntub dej kuj tseem tuaj yeem txhim kho kev tiv thaiv hauv qhov chaw nyuaj. Tab sis nws qhov kev tiv thaiv rau corrosion hnyav yog txwv thiab txo qis nrog qhov kub siab thiab qhov nruab nrab corrosive concentration. Hauv qhov xwm txheej ntawd yuav tsum xav txog hloov hlau tsis xeb ntawm qhov ntub dej thiab diaphragm nrog lwm cov khoom siv zoo dua.
Monel:
Muaj ib qho hlau nickel uas ua los ntawm nickel hu ua monel. Cov hlau no ruaj khov dua li nickel ntshiab thiab tiv thaiv xeb hauv ntau yam kua qaub thiab dej ntsev. Hauv kev siv hauv hiav txwv thiab dej hiav txwv, monel series alloy feem ntau yog cov kev xaiv nrov rau cov khoom siv diaphragm. Txawm li cas los xij, cov khoom siv kim heev thiab qee zaum tsuas yog pom zoo thaum cov kev xaiv pheej yig tsis ua tau thiab nws tsis haum rau cov xwm txheej oxidizing.
