I-Electromagnetic flowmeter sisixhobo esisebenzisa umgaqo wokungeniswa kwe-electromagnetic ukulinganisa ukuhamba kolwelo oluqhubayo olusekwe kumandla ombane owenziweyo xa ulwelo oluqhubayo ludlula kwindawo yangaphandle yemagnethi.
Ngoko unokukhetha njani umgca wangaphakathi kunye nezinto ze-electrode?
Ukukhethwa kweMathiriyeli yeLining
■ I-Neoprene (CR):
Ipolymer eyenziwe yi-emulsion polymerization ye-chloroprene monomer. Le molekyuli yerabha iqulethe iiathom zeklorin, ngoko ke xa ithelekiswa nezinye irabha yenjongo jikelele: Ine-anti-oxidation egqwesileyo, i-anti-ozone, engatshiyo, izicima ngokwayo emva komlilo, ukunganyangeki kwe-oyile, ukunganyangeki kwe-solvent, ukumelana ne-asidi kunye ne-alkali, kunye nokuguga. kunye nokumelana negesi. Ukuqina okuhle kunye nezinye iingenelo.
✔ Ilungele ukulinganisa ukuhamba kwamanzi epompo, amanzi amashishini, amanzi olwandle kunye nezinye imidiya.
■ Irabha yepolyurethane (PU):
I-polymerized yi-polyester (okanye i-polyether) kunye ne-disocyanamide lipid compound. Ineengenelo zobulukhuni obuphezulu, ukomelela okuhle, ukuqina okuphezulu, ukuxhathisa kokunxiba, ukuxhathisa ukukrazuka, ukuxhathisa ukwaluphala, ukuxhathisa kwe-ozone, ukuxhathisa kwimitha kunye nokuhanjiswa kakuhle kombane.
✔ Ifanelekile kumlinganiselo wokuqukuqela kwemithombo yeendaba eludaka njengepulp kunye ne-ore pulp.
■I-Polytetrafluoroethylene ( P4-PTFE )
Yipolymer elungiselelwe yi-polymerization ye-tetrafluoroethylene njenge-monomer. I-waxy emhlophe, i-translucent, ukumelana nobushushu, ukumelana nokubanda, inokusetyenziswa kwi -180 ~ 260 °C ixesha elide. Esi sixhobo sineempawu zokumelana ne-asidi kunye ne-alkali, ukuxhathisa kwiintlobo ezahlukeneyo ze-solvents eziphilayo, ukuchasana nokubilisa i-hydrochloric acid, i-sulfuric acid, i-aqua regia, i-alkali corrosion.
✔ Ingasetyenziselwa i-asidi edliwayo kunye nolwelo lwetyuwa yealkali.
■I-Polyperfluoroethylene propylene ( F46-FEP )
Inozinzo olugqwesileyo lweekhemikhali kunye nokumelana okubalaseleyo kwimitha, kunye nokungatsha, kunye neempawu ezilungileyo zombane kunye nezoomatshini. Iimpawu zayo zeekhemikhali zilingana ne-polytetrafluoroethylene, kunye nokunyanzeliswa okunamandla kunye namandla anamandla angcono kune-polytetrafluoroethylene.
✔ Ingasetyenziselwa i-asidi edliwayo kunye nolwelo lwetyuwa yealkali.
■I-copolymer ye-tetrafluoroethylene kunye ne-perfluorocarbon nge-vinyl ether (PFA)
Isixhobo sombane se-electromagnetic flowmeter ineempawu zekhemikhali ezifanayo njenge-F46 kunye namandla angcono okuqina kune-F46.
✔Ingasetyenziselwa i-asidi edliwayo kunye nolwelo lwetyuwa yealkali.
Electrode Material Selection
