Electromagnetic flowmeter nigikoresho gikoresha ihame rya induction ya electromagnetic kugirango bapime urujya n'uruza rw'amazi ashingiye ku mbaraga z'amashanyarazi zatewe iyo amazi atembera anyuze mu murima wa rukuruzi.
Nigute ushobora guhitamo imbere imbere nibikoresho bya electrode?
Guhitamo Ibikoresho
Op Neoprene (CR):
Polimeri yakozwe na emulsion polymerisation ya chloroprene monomer. Iyi molekile ya reberi irimo atome ya chlorine, ugereranije nizindi reberi rusange igamije: Ifite anti-okiside nziza, anti-ozone, idacana, yizimya nyuma yumuriro, kurwanya amavuta, kurwanya ibishishwa, aside irwanya alkali, no gusaza no kurwanya gaze. Gukomera hamwe nibindi byiza.
✔ Irakwiriye gupimwa kumazi ya robine, amazi yinganda, amazi yinyanja nibindi bitangazamakuru.
Rub Rubure ya Polyurethane (PU):
Ihindurwa na polyester (cyangwa polyether) hamwe na diisocyanamide lipid compound. Ifite ibyiza byo gukomera cyane, imbaraga nziza, elastique nyinshi, kwihanganira kwambara cyane, kurwanya amarira, kurwanya gusaza, kurwanya ozone, kurwanya imirasire hamwe no gukoresha amashanyarazi meza.
✔ Birakwiriye gupima ibipimo byitangazamakuru ryihuta nka pulp na ore pulp.
■Polytetrafluoroethylene (P4-PTFE)
Ni polymer yateguwe na polymerisation ya tetrafluoroethylene nka monomer. Ibishashara byera, byoroshye, birwanya ubushyuhe, birwanya ubukonje, birashobora gukoreshwa muri -180 ~ 260 ° C igihe kirekire. Ibi bikoresho bifite ibiranga aside na alkali birwanya, kurwanya imiti itandukanye kama, kurwanya aside hydrochloric itetse, aside sulfurike, aqua regia, ruswa ya alkali.
✔ Irashobora gukoreshwa kuri aside yangirika hamwe namazi yumunyu wa alkali.
■Polyperfluoroethylene propylene (F46-FEP)
Ifite imiti ihamye kandi irwanya imirasire idasanzwe, kimwe no kudakongoka, ibintu byiza byamashanyarazi nubukanishi. Imiterere yimiti ihwanye na polytetrafluoroethylene, hamwe nimbaraga zikomeye zo gukomeretsa no gukomera biruta polytetrafluoroethylene.
✔ Irashobora gukoreshwa kuri aside yangirika hamwe namazi yumunyu wa alkali.
■Copolymer ya tetrafluoroethylene na perfluorocarbon ikoresheje vinyl ether (PFA)
Ibikoresho bitondekanya amashanyarazi ya electromagnetic bifite imiterere ya chimique nka F46 nimbaraga nziza zirenze F46.
✔Irashobora gukoreshwa kuri aside yangirika hamwe namazi yumunyu wa alkali.
Guhitamo Ibikoresho bya Electrode
| 316L | Irakwiriye imyanda yo mu ngo, imyanda ituruka mu nganda, amazi meza, imyanda yo mu mijyi, nibindi, hamwe nudukoko twangiza aside-ishingiye kumunyu. |
| Hastelloy (HB) | Bikwiranye na acide idafite okiside nka aside hydrochloric (concentration iri munsi ya 10%). Sodium hydroxide (concentration iri munsi ya 50%) sodium hydroxide alkali igisubizo cyibitekerezo byose. Acide ya fosifori cyangwa aside organic, nibindi, ariko aside nitric ntabwo ikwiye. |
| Hastelloy (HC) | Acide ivanze nigisubizo kivanze cya acide chromic na acide sulfurike. Oxidizing umunyu nka Fe +++, Cu ++, amazi yo mu nyanja, aside fosifori, acide organic, nibindi, ariko ntibikwiriye aside aside. |
| Titanium (Ti) | Bikoreshwa kuri chloride (nka sodium chloride / magnesium chloride / calcium chloride / ferric chloride / ammonium chloride / aluminium chloride, nibindi), umunyu (nk'umunyu wa sodium, umunyu wa amonium, hypofluorite, umunyu wa potasiyumu, amazi yo mu nyanja), aside nitric (ariko hatabariwemo no gusohora aside nitric), alkalis hamwe na concentration ≤50% mubushyuhe bwicyumba (potassium hydroxide, sodium hydroxide, hydroxide ya barium, nibindi) ariko ntibikurikizwa: aside hydrochloric, aside sulfurike, aside fosifori, aside hydrofluoric, nibindi. |
| Tantalum electrode (Ta) | Bikwiranye na hydrochloric aside (concentration ≤ 40%), kuvanga aside sulfurike na acide sulfurike yibanze (ukuyemo aside nitricike). Ikoreshwa kuri dioxyde ya chlorine, chloride ferric, acide hypofluorous, aside hydrobromic, sodium cyanide, gurşide acetate, aside nitricike (harimo na acide nitric) na aqua regia ubushyuhe buri munsi ya 80 ° C. Ariko ibi bikoresho bya electrode ntibikwiriye alkali, aside hydrofluoric, amazi. |
| Electrode ya platine (Pt) | Bikoreshwa hafi ya acide-fatizo yumunyu mwinshi (harimo gusohora aside nitric, fuming acide sulfurike), ntabwo ikoreshwa: aqua regia, umunyu wa amoniya, hydrogen peroxide, aside hydrochloric yibanze (> 15%). |
Ibiri hejuru nibisobanuro gusa, nyamuneka reba ikizamini nyirizina. Birumvikana ko ushobora no kutugisha inama. Tuzaguha ibitekerezo bimwe.
Isosiyete yacu ikora kandi ibikoresho byabigenewe kubikoresho bifitanye isano, harimo electrode, diafragma yicyuma, impeta zo hasi, flanges ya diaphragm, nibindi.
Nyamuneka kanda kugirango urebe ibicuruzwa bifitanye isano, urakoze.(Whatsapp / Wechat: +86 156 1977 8518)
