Hauv kev ntsuas tus txheej txheem, ib qho ntawm cov lus teb rau corrosive ntsuas nruab nrab yog siv cov khoom tsim nyog resistant rau corrosion rau ntsuas qhov wetted-sensing diaphragm los yog nws txheej, hluav taws xob cov ntaub ntawv los yog lwm yam yuav tsum tau qhov chaw thiab fittings.
PTFE:
PTFE (Polytetrafluoroethylene) yog ib hom mos, hnav thiab tsis tshua muaj kev sib txhuam engineering yas uas muaj cov tshuaj tiv thaiv corrosion zoo heev. Nws yog ib qho kev daws teeb meem zoo rau kev txhoj puab heev hauv kev ua tshuaj lom neeg thiab roj & roj kev lag luam. Txawm li cas los xij, nws yuav tsum paub txog tias PTFE tsis siv rau hauv qhov kub thiab txias tshaj 260 ℃, tsis tshua muaj zog ua rau nws kuj tsis haum rau cov xov lossis cov khoom siv diaphragm.
Tantalum:
Tantalum yog ib qho tshwj xeeb corrosion-resistant hlau uas muaj peev xwm tiv taus ntau yam tshuaj lom neeg, ua rau nws muaj kev xaiv zoo tshaj plaws rau kev hnov cov khoom siv diaphragm rau cov xov xwm corrosive heev. Txawm li cas los xij, cov hlau yog kim kim thiab tsis siv ntau npaum li lwm cov ntaub ntawv. Nyob rau hauv cov txheej txheem tshuaj uas tswj cov acids nruj heev, lub siab sensor nruab nrog tantalum sensing diaphragm yog zoo kawg nkaus tsim nyog rau txoj hauj lwm kom ua tiav qib siab tshaj ntawm corrosion kuj.
Ceramic:
Ceramic yog ib qho khoom siv zoo inorganic non-metallic uas ua rau muaj kev tiv thaiv zoo rau qhov kub thiab txias. Piezoresistive / capacitance sensors nrog zirconia lossis alumina ceramic membrane feem ntau siv rau hauv cov tshuaj, tshuaj, thiab zaub mov & dej haus. Nws tseem yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias tsis yog hlau, ceramic yog nkig kom cov sensors ceramic tsis haum rau kev cuam tshuam siab, thermal shock thiab siab daim ntawv thov thiab xav tau kev saib xyuas ntxiv thaum tuav.
Hastelloy Alloy:
Hastelloy yog ib tug series ntawm npib tsib xee-raws li alloys, ntawm uas C-276 qhia zoo tagnrho corrosion kuj thiab yog feem ntau xaiv raws li cov khoom rau ntsuas diaphragm thiab lwm yam wetted qhov chaw tiv thaiv corrosive xov xwm. C-276 alloy yog siv nyob rau hauv feem ntau cov chaw lag luam uas muaj tshuaj lom neeg mob hnyav tau nthuav tawm thiab lwm yam khoom siv yuav ua tsis tau.
Stainless hlau 316L:
Feem ntau hom stainless hlau siv rau qhov ntsuas diaphragm yog qib 316L. SS316L muaj qhov nruab nrab corrosion tsis kam, zoo txhua yam khoom thiab tus nqi pheej yig. Stainless hlau plhaub ntawm cov tsev tsis-wetted tuaj yeem txhim kho kev tiv thaiv hauv ib puag ncig hnyav. Tab sis nws tsis kam mus rau huab cua corrosion yog txwv thiab txo nrog kub siab thiab corrosive nruab nrab concentration. Nyob rau hauv tas li ntawd, kev txiav txim siab yuav tsum tau muab coj los hloov stainless hlau ntawm wetted ib feem thiab diaphragm nrog rau lwm cov ntaub ntawv superior.
Monel:
Ib qho ntxiv nickel-based alloy hu ua monel. Cov hlau muaj zog ntau dua li npib tsib xee ntshiab thiab tiv thaiv corrosive hauv ntau cov kua qaub thiab dej ntsev. Hauv offshore thiab marine siv monel series alloy feem ntau yog ib qho kev xaiv nrov rau cov khoom siv diaphragm. Txawm li cas los xij, cov khoom siv kim heev thiab qee zaum tsuas yog xav tau thaum cov nqi qis dua tsis ua tau thiab nws tsis haum rau oxidizing tej yam kev mob.
ShanghaiWangYuanyog ib lub chaw tsim khoom ntawm kev siab, qib, kub thiab ntws ntsuas ntsuas rau ntau tshaj 20 xyoo. Peb cov qub tub rog engineers muaj peev xwm los nthuav qhia qhov kev daws teeb meem zoo rau kev sib tw ntawm txhua yam kev mob corrosive. Thov koj xav tiv tauj peb kom paub meej cov kev ntsuas rau cov txheej txheem tshwj xeeb.
