Ekulinganisweni kwenqubo, enye yezindlela eziyisisekelo zokulinganisa izinto ezigqwalisayo ukusebenzisa izinto ezifanele ezingamelana nokugqwala kwengxenye yethuluzi emanzi, i-diaphragm yokuzwa noma ukumbozwa kwayo, ikesi likagesi noma ezinye izingxenye ezidingekayo kanye nokufakwa.
I-PTFE:
I-PTFE (i-Polytetrafluoroethylene) uhlobo olulodwa lwepulasitiki yobunjiniyela ethambile, elula futhi ephansi yokungqubuzana enokumelana okuhle kakhulu nokugqwala kwamakhemikhali. Iyisisombululo esingabizi kakhulu sesimo esinamandla ezimbonini zokucubungula amakhemikhali kanye ne-oyela negesi. Kodwa-ke, kufanele kuqashelwe ukuthi i-PTFE ayisebenzi emazingeni okushisa aphezulu okusebenza angaphezu kuka-260℃, ubulukhuni obuphansi buyenza ingafaneleki ukuba yintambo noma i-diaphragm.
I-Tantalum:
I-Tantalum iyinsimbi engagqwali kakhulu ekwazi ukumelana namakhemikhali ahlukahlukene anolaka, okwenza kube inketho enhle kakhulu yokuzwa izinto ze-diaphragm zezinto ezigqwala kakhulu. Noma kunjalo, insimbi iyabiza kakhulu futhi ayisetshenziswa kakhulu njengezinye izinto. Ohlelweni lwenqubo yamakhemikhali oluphatha ama-asidi anolaka kakhulu, inzwa yokucindezela efakwe i-diaphragm yokuzwa ye-tantalum ifaneleka ngokuphelele kulesi sikhundla ukuze ifinyelele izinga eliphezulu lokumelana nokugqwala.
I-Ceramic:
I-Ceramic iyinto enhle engeyona eyensimbi engabonakali ekhombisa ukumelana okuvelele ekushiseni okuphezulu kanye nokugqwala. Izinzwa ze-piezoresistive/capacitance ezine-zirconia noma i-alumina ceramic membrane zivame ukusetshenziswa emikhakheni yamakhemikhali, yezemithi, kanye neyokudla neziphuzo. Kubalulekile futhi ukuqaphela ukuthi njengoba ingeyona eyensimbi, i-ceramic iyaphuka ukuze izinzwa ze-ceramic zingafaneleki ekushayweni okuphezulu, ukushaqeka kokushisa kanye nokusetshenziswa kwengcindezi futhi zidinga ukunakekelwa okwengeziwe ngenkathi ziphathwa.
I-Hastelloy Alloy:
I-Hastelloy uchungechunge lwe-alloys esekelwe ku-nickel, lapho i-C-276 ikhombisa ukumelana okuhle kokugqwala futhi ivame ukukhethwa njengezinto zokwakha i-diaphragm yensimbi nezinye izingxenye ezimanzi ngokumelene nemidiya egqwalisayo. I-alloy ye-C-276 isetshenziswa ezindaweni eziningi zezimboni lapho kuvela khona izimo zamakhemikhali ezinamandla futhi ezinye izinto zingase zehluleke.
Insimbi Engagqwali 316L:
Uhlobo lwensimbi engagqwali oluvame kakhulu olusetshenziselwa i-diaphragm yokuzwa yi-grade 316L. I-SS316L inokumelana nokugqwala okulinganiselwe, izakhiwo ezinhle zemishini kanye nezindleko ezingabizi. Igobolondo lensimbi engagqwali lendlu engamanzi lingathuthukisa nokuvikelwa endaweni enzima. Kodwa ukumelana kwayo nokugqwala okukhulu kunqunyelwe futhi kwehla ngokushisa okuphezulu kanye nokuhlushwa okuphakathi okugqwalayo. Kuleso simo kufanele kucatshangelwe ukufaka esikhundleni sensimbi engagqwali engxenyeni emanzi kanye ne-diaphragm ngezinye izinto ezinhle.
I-Monel:
Enye ingxubevange esekelwe ku-nickel ibizwa ngokuthi i-monel. Insimbi iqine kakhulu kune-nickel emsulwa futhi ayiboli kuma-asidi ahlukahlukene kanye namanzi anosawoti. Ekusetshenzisweni kwasogwini kanye nolwandle, ingxubevange ye-monel ivame ukuba yindlela ethandwayo yokukhetha izinto ze-diaphragm. Kodwa-ke, le nto ibiza kakhulu futhi ngezinye izikhathi iyalulekwa kuphela uma ezinye izindlela ezingabizi kakhulu zingenakwenzeka futhi zingafaneleki ezimweni zokuxilisa.
IShanghaiWangYuaningumkhiqizi onolwazi wezinsimbi zokulinganisa ingcindezi, izinga, izinga lokushisa kanye nokugeleza iminyaka engaphezu kwengu-20. Onjiniyela bethu abangochwepheshe bayakwazi ukwethula ikhambi elifanele lezinselelo zazo zonke izinhlobo zezimo ezigqwalisayo. Sicela uzizwe ukhululekile ukuxhumana nathi ukuthola izindlela ezinemininingwane zokusetshenziswa kwenqubo ethile.
