Electromagnetic flowmeter kayan aiki ne da ke amfani da ka'idar shigar da wutar lantarki don auna magudanar ruwan da ke bisa karfin wutar lantarki da aka jawo lokacin da ruwan tafiyar ya ratsa ta filin maganadisu na waje.
Don haka yadda za a zabi kayan ciki da kayan lantarki?
Zaɓin Kayan Kayan Rubutu
Neoprene (CR):
A polymer kafa ta emulsion polymerization na chloroprene monomer. Wannan kwayar halitta ta roba tana dauke da kwayoyin zarra na chlorine, don haka idan aka kwatanta da sauran roba na gaba daya: Yana da kyakkyawan anti-oxidation, anti-ozone, non-flammable, mai kashe kansa bayan wuta, juriyar mai, juriya na acid, juriya na alkali, da tsufa. da juriya na iskar gas. Kyakkyawan matsi da sauran fa'idodi.
✔ Ya dace da ma'aunin ruwan famfo, ruwan masana'antu, ruwan teku da sauran kafofin watsa labarai.
■ Rubber Polyurethane (PU):
An yi shi da polyester (ko polyether) da diisocyamide lipid fili. Yana da abũbuwan amfãni daga high taurin, mai kyau ƙarfi, high elasticity, high lalacewa juriya, hawaye juriya, tsufa juriya, lemar ozone juriya, radiation juriya da kuma mai kyau lantarki watsin.
✔ Ya dace da auna kwararar kafofin watsa labaru kamar ɓangaren litattafan almara da ɓangaren litattafan almara.
■Polytetrafluoroethylene (P4-PTFE)
Yana da polymer wanda aka shirya ta hanyar polymerization na tetrafluoroethylene a matsayin monomer. White waxy, translucent, zafi juriya, sanyi juriya, za a iya amfani da a -180 ~ 260 ° C na dogon lokaci. Wannan abu yana da halaye na acid da alkali juriya, juriya ga daban-daban Organic kaushi, jure tafasasshen hydrochloric acid, sulfuric acid, aqua regia, mayar da hankali alkali lalata.
✔ Ana iya amfani dashi don lalata acid da ruwa gishiri alkali.
■Polyperfluoroethylene propylene (F46-FEP)
Yana da kyakkyawan kwanciyar hankali na sinadarai da juriya na radiation, da rashin ƙonewa, kyawawan kaddarorin lantarki da na inji. Abubuwan sinadaransa suna daidai da polytetrafluoroethylene, tare da ƙarfi mai ƙarfi da ƙarfi mai ƙarfi ya fi polytetrafluoroethylene kyau.
✔ Ana iya amfani dashi don lalata acid da ruwa gishiri alkali.
■Copolymer na tetrafluoroethylene da perfluorocarbon ta vinyl ether (PFA)
Kayan rufi na lantarki na lantarki yana da kaddarorin sinadarai iri ɗaya kamar F46 kuma mafi kyawun ƙarfi fiye da F46.
✔Ana iya amfani dashi don lalata acid da ruwa gishiri alkali.
