Esilinganisweni senqubo, enye yempendulo ebalulekile endleleni yokulinganisa ebolayo ukusebenzisa impahla efanele ukumelana nokugqwala kwengxenye emanzi yensimbi, i-diaphragm ezwayo noma ukunamathela kwayo, ikesi le-elekthronikhi noma ezinye izingxenye ezidingekayo nokufakwa.
I-PTFE:
I-PTFE(Polytetrafluoroethylene) iwuhlobo olulodwa lwepulasitiki yobunjiniyela ethambile, engasindi futhi eshayisana kancane enokumelana nokugqwala kwamakhemikhali okuvelele. Kuyisixazululo esingabizi kakhulu sesimo esinolaka ekucutshungulweni kwamakhemikhali nezimboni zikawoyela nezegesi. Kodwa-ke, kufanele kuqashelwe ukuthi i-PTFE ayisebenzi ekushiseni okwedlulele kokusebenza okungaphezulu kuka-260℃, ubulukhuni obuphansi buyenza futhi ingafaneleki ukuba yintambo noma impahla ye-diaphragm.
I-Tantalum:
I-Tantalum iyinsimbi ekwazi ukumelana nokugqwala ekwazi ukumelana namakhemikhali ahlukahlukene, okuyenza ibe inketho enhle kakhulu yokuzwa izinto ze-diaphragm zemidiya egqwala kakhulu. Noma kunjalo, insimbi ibiza kakhulu futhi ayijwayele ukusetshenziswa njengezinye izinto. Ohlelweni lwenqubo yamakhemikhali olulawula ama-asidi anolaka kakhulu, inzwa yokucindezela efakwe i-tantalum sensing diaphragm ifaneleka ngokuphelele isikhundla sokufinyelela izinga eliphakeme kakhulu lokumelana nokugqwala.
I-Ceramic:
I-Ceramic iyinto ehloniphekile ye-inorganic non-metallic ebonisa ukumelana okuvelele ekushiseni okuphezulu nokugqwala. Izinzwa ze-piezoresistive/capacitance ezine-zirconia noma i-alumina ceramic membrane zivame ukusetshenziswa emikhakheni yamakhemikhali, eyekhemisi, neyokudla neziphuzo. Kubalulekile futhi ukuqaphela ukuthi njenge-nonmetal, i-ceramic i-brittle ukuze izinzwa ze-ceramic azifaneleki umthelela ophezulu, ukushaqeka okushisayo nokufakwa kwengcindezi futhi zidinga ukunakekelwa okwengeziwe ngenkathi uphatha.
I-Hastelloy Alloy:
I-Hastelloy iwuchungechunge lwama-alloys asekelwe ku-nickel, lapho i-C-276 ibonisa ukumelana nokugqwala okufanele futhi ivame ukukhethwa njengento esetshenziswayo ye-diaphragm yensimbi nezinye izingxenye ezimanzi ngokumelene nemidiya egqwalayo. Ingxubevange ye-C-276 isetshenziswa kuzilungiselelo eziningi zezimboni lapho izimo zamakhemikhali ezinolaka zethulwa kanye nokunye okubalulekile okungenzeka kuhlulekile.
Insimbi Engagqwali 316L:
Uhlobo oluvame kakhulu lwensimbi engagqwali olusetshenziselwa i-diaphragm yokuzwa yibanga 316L. I-SS316L inokumelana nokugqwala okusesilinganisweni, izakhiwo zemishini ehloniphekile nezindleko ezithengekayo. Igobolondo lensimbi engagqwali lezindlu ezingamanziswanga nazo zingathuthukisa ukuvikeleka endaweni enokhahlo. Kodwa ukumelana kwayo nokugqwala okudlulele kulinganiselwe futhi kuncipha ngezinga lokushisa eliphakeme kanye nokugxila okuphakathi okugqwalayo. Kuleso simo kufanele kucatshangelwe ukufaka esikhundleni sensimbi engagqwali engxenyeni emanzi kanye ne-diaphragm nezinye izinto eziphakeme.
I-Monel:
Enye i-alloy esekelwe ku-nickel ibizwa ngokuthi i-monel. Insimbi iqine kakhulu kune-nickel ehlanzekile futhi ivimbela ukugqwala kuma-acids ahlukahlukene kanye namanzi anosawoti. Ngasogwini nasolwandle kusetshenziswa i-monel series alloy ngokuvamile iyisinqumo esidumile se-diaphragm material. Kodwa-ke, okokusebenza kubiza kakhulu futhi kwesinye isikhathi kuyafaneleka kuphela lapho ezinye izindleko eziphansi zingenzeki futhi zingafaneleki ezimeni ze-oxidizing.
ShanghaiWangYuanungumkhiqizi onolwazi wamathuluzi wokulinganisa ingcindezi, izinga, izinga lokushisa kanye nokugeleza iminyaka engaphezu kwengu-20. Onjiniyela bethu abangomakadebona bayakwazi ukwethula isixazululo esifanelekile sezinselele zazo zonke izinhlobo zezimo ezigqwalile. Sicela uzizwe ukhululekile ukuxhumana nathi ukuze uthole izinyathelo zemininingwane yezinhlelo zokusebenza ezithile zenqubo.
