I-Electromagnetic flowmeter iyithuluzi elisebenzisa umgomo wokungeniswa kuka-electromagnetic ukukala ukugeleza koketshezi oluguquguqukayo olususelwe kumandla we-electromotive akhangwa lapho uketshezi lwe-conductive ludlula endaweni kazibuthe yangaphandle.
Ngakho-ke ungakhetha kanjani ulwelwesi lwangaphakathi kanye nezinto ze-electrode?
Ukukhethwa Kwezinto Zokulala
■ I-Neoprene (CR):
I-polymer eyakhiwe nge-emulsion polymerization ye-chloroprene monomer.Le molecule yenjoloba iqukethe ama-athomu e-chlorine, ngakho-ke uma iqhathaniswa nezinye irabha yenjongo evamile: Ine-anti-oxidation enhle kakhulu, i-anti-ozone, engashi, izicisha ngokwayo ngemva komlilo, ukumelana nowoyela, ukumelana ne-solvent, ukumelana ne-asidi ne-alkali, nokuguga. kanye nokumelana negesi.Ukuqina okuhle nezinye izinzuzo.
✔ Ilungele ukukala kokugeleza kwamanzi kampompi, amanzi ezimboni, amanzi olwandle kanye neminye imidiya.
■ Irabha ye-polyurethane (PU):
I-polymerized nge-polyester (noma i-polyether) kanye ne-disocyanamide lipid compound.Inezinzuzo zobulukhuni obuphezulu, amandla amahle, ukunwebeka okuphezulu, ukumelana nokugqoka okuphezulu, ukumelana nezinyembezi, ukumelana nokuguga, ukumelana ne-ozone, ukumelana nemisebe kanye nokuhamba kahle kukagesi.
✔ Ilungele ukukalwa kokugeleza kwemithombo ye-slurry efana ne-pulp ne-ore pulp.
■I-Polytetrafluoroethylene (P4-PTFE)
Kuyi-polymer elungiselelwe i-polymerization ye-tetrafluoroethylene njenge-monomer.I-waxy emhlophe, i-translucent, ukumelana nokushisa, ukumelana nokubanda, ingasetshenziswa ku -180 ~ 260 ° C isikhathi eside.Le nto inezici zokuphikiswa kwe-asidi ne-alkali, ukumelana nezinyibilikisi ezihlukahlukene eziphilayo, ukumelana nokubilisa i-hydrochloric acid, i-sulfuric acid, i-aqua regia, ukugqwala kwe-alkali okugxilile.
✔ Ingasetshenziselwa i-acid ebolayo kanye ne-alkali uketshezi lukasawoti.
■I-Polyperfluoroethylene propylene (F46-FEP)
Inokuqina okuhle kwamakhemikhali kanye nokumelana okuvelele emisebeni, kanye nokungashi, izici ezinhle zikagesi kanye nemishini.Amakhemikhali ayo alingana ne-polytetrafluoroethylene, enamandla okucindezelayo namandla aqinile angcono kune-polytetrafluoroethylene.
✔ Ingasetshenziselwa i-acid ebolayo kanye ne-alkali uketshezi lukasawoti.
■I-copolymer ye-tetrafluoroethylene ne-perfluorocarbon nge-vinyl ether (PFA)
Impahla yolwelwesi ye-electromagnetic flowmeter inezindawo zamakhemikhali ezifanayo njenge-F46 namandla angcono okubamba kune-F46.
✔Ingasetshenziselwa i-acid ebolayo kanye ne-alkali uketshezi lukasawoti.
Ukukhetha Okubalulekile kwe-Electrode
| 316L | Ilungele indle yasekhaya, indle yasezimbonini, amanzi omthombo, indle yasemadolobheni, njll., kanye nezixazululo ezibuthakathaka ze-acid-base salt solutions. |
| I-Hastelloy (HB) | Ifanele ama-asidi angenayo i-oxidizing njenge-hydrochloric acid (ukugxila ngaphansi kuka-10%).I-sodium hydroxide (ukugxila ngaphansi kuka-50%) isixazululo se-alkali ye-sodium hydroxide yakho konke ukugxila.I-Phosphoric acid noma i-organic acid, njll., kodwa i-nitric acid ayifanele. |
| I-Hastelloy (HC) | Ingxube ye-asidi nesisombululo esixubile se-chromic acid ne-sulfuric acid.Ama-oxidizing salts afana ne-Fe+++, Cu++, amanzi olwandle, i-phosphoric acid, i-organic acid, njll., kodwa ayifanele i-hydrochloric acid. |
| I-Titanium (Ti) | Isebenza kuma-chloride (njenge-sodium chloride/magnesium chloride/calcium chloride/ferric chloride/ammonium chloride/aluminium chloride, njll.), usawoti (njengosawoti we-sodium, usawoti we-ammonium, i-hypofluorite, usawoti we-potassium, amanzi olwandle) , i-nitric acid (kodwa okungabandakanyi i-nitric acid evuthayo), ama-alkali ane-concentration ≤50% ekamelweni lokushisa (i-potassium hydroxide, i-sodium hydroxide, i-barium hydroxide, njll.) kodwa ayisebenzi: i-hydrochloric acid, i-sulfuric acid, i-phosphoric acid, i-hydrofluoric acid, njll. |
| I-Tantalum electrode (Ta) | Ifanele i-hydrochloric acid (i-concentration ≤ 40%), i-dilute sulfuric acid kanye ne-concentrated sulfuric acid (ngaphandle kwe-fuming nitric acid).Isebenza ku-chlorine dioxide, i-ferric chloride, i-hypofluorous acid, i-hydrobromic acid, i-sodium cyanide, i-lead acetate, i-nitric acid (kuhlanganise ne-fuming nitric acid) ne-aqua regia izinga lokushisa layo lingaphansi kuka-80°C.Kodwa le nto ye-electrode ayifanele i-alkali, i-hydrofluoric acid, amanzi. |
