Electromagnetic flowmeter waa aalad adeegsata mabda'a induction elektromagnetic si loo cabbiro qulqulka dareeraha korantada ee ku saleysan xoogga korantada ee la kiciyo marka dareeraha korantada uu marayo goob birlab ah oo dibadda ah.
Haddaba sidee loo doortaa xuubka gudaha iyo qalabka korantada?
Xulashada Qalabka Dahaarka
■ Neoprene (CR):
polymer ah oo lagu sameeyay polymerization emulsion ee monomer chloroprene. Unugyada caagga ah waxay ka kooban yihiin atomyada chlorine, marka la barbar dhigo caag kale oo ujeedo guud ah: Waxay leedahay anti-oxidation heer sare ah, anti-ozone, aan guban, is-deminta dabka ka dib, caabbinta saliidda, caabbinta dareeraha, caabbinta acid iyo alkali, iyo gabowga. iyo caabbinta gaaska. Cidhiidhi wanaagsan iyo faa'iidooyin kale.
✔ Waxay ku habboon tahay cabbirka socodka biyaha tuubada, biyaha warshadaha, biyaha badda iyo warbaahinta kale.
■ Caag polyurethane (PU):
Waxaa polymerized by polyester (ama polyeter) iyo xuubka dufanka diisocyanamide. Waxay leedahay faa'iidooyinka adkaanta sare, xoog wanaagsan, dabacsanaan sare, caabbinta xirashada sare, caabbinta ilmada, caabbinta gabowga, caabbinta ozone, caabbinta shucaaca iyo korantada wanaagsan.
✔ Waxay ku habboon tahay cabbirka qulqulka warbaahinta qulqulka sida saxarka iyo saxarka macdanta.
■Polytetrafluoroethylene (P4-PTFE)
Waa polymer lagu diyaariyey polymerization tetrafluoroethylene sida monomer ahaan. Waxy cad, translucent, iska caabin kulaylka, iska caabin qabow, waxaa loo isticmaali karaa in -180 ~ 260 ° C muddo dheer. Qalabkani wuxuu leeyahay sifooyinka caabbinta acid iyo alkali, iska caabinta dareerayaasha kala duwan ee organic, caabbinta karkarinta hydrochloric acid, sulfuric acid, aqua regia, daxalka alkali ee xoogga leh.
✔ Waxa loo isticmaali karaa aashitada wasakhaysan iyo dareeraha cusbada alkali.
■Polyperfluoroethylene propylene (F46-FEP)
Waxay leedahay xasillooni kiimikaad oo heer sare ah iyo iska caabin shucaac heersare ah, iyo sidoo kale olol la'aan, sifooyin koronto iyo farsamooyin wanaagsan. Alaabta kiimikada ah waxay u dhigantaa polytetrafluoroethylene, oo leh xoog cufan iyo cufan ayaa ka fiican polytetrafluoroethylene.
✔ Waxa loo isticmaali karaa aashitada wasakhaysan iyo dareeraha cusbada alkali.
■Copolymer ee tetrafluoroethylene iyo perfluorocarbon iyada oo loo sii marayo vinyl ether (PFA)
Maaddada dahaarka ee qulqulka elektiroonigga ah waxay leedahay sifooyin kiimikaad oo la mid ah tan F46 iyo xoogga xajinta oo ka wanaagsan F46.
✔Waxa loo isticmaali karaa aashitada wasakhaysan iyo dareeraha cusbada alkali.
Doorashada Qalabka Electrode
| 316L | Waxay ku habboon tahay bullaacadaha gudaha, bulaacada warshadaha, biyaha ceelasha, bulaacada magaalooyinka, iwm., iyo xalalka cusbada ee acid-saldhigga daciifka ah. |
| Hastelloy (HB) | Ku habboon aashitada aan oksaydhism-ka lahayn sida hydrochloric acid (fiirsashada wax ka yar 10%). Sodium hydroxide (fiirsashada in ka yar 50%) sodium hydroxide alkali xalalka dhammaan uruurinta. Fosfooraska ama aashitada organic, iwm., laakiin nitric acid kuma habboona. |
| Hastelloy (HC) | Asiidh isku dhafan iyo xal isku dhafan oo ah chromic acid iyo sulfuric acid. Oxidizing cusbada sida Fe+++, Cu++, biyaha badda, phosphoric acid, organic acids, iwm, laakiin aan ku haboonayn hydrochloric acid. |
| Titanium (Ti) | Lagu dabaqi karo chlorides (sida sodium chloride/magnesium chloride/calcium chloride/ferric chloride/ammonium chloride/aluminium chloride, iwm.), cusbada (sida cusbada sodium, cusbada ammonium, hypofluorite, cusbada potassium, biyaha badda) , nitric acid (laakiin oo aan ku jirin nitric acid fuming), alkalis leh feejignaan ≤50% heerkulka qolka (potassium hydroxide, sodium hydroxide, barium hydroxide, iwm.) laakiin aan lagu dabaqi karin: hydrochloric acid, sulfuric acid, phosphoric acid, hydrofluoric acid, iwm. |
| Tantalum electrode (Ta) | Ku habboon aashitada hydrochloric (fiirsashada ≤ 40%), sulfuric acid milmi iyo sulfuric acid (marka laga reebo fuming nitric acid). Lagu dabaqi karo chlorine dioxide, ferric chloride, hypofluorous acid, hydrobromic acid, sodium cyanide, lead acetate, nitric acid (ay ku jirto fuming nitric acid) iyo aqua regia oo heerkulkeedu ka hooseeyo 80°C. Laakiin qalabkan elektiroonigga ah kuma habboona alkali, hydrofluoric acid, biyaha. |
| Platinum electrode (Pt) | Lagu dabaqi karo ku dhawaad dhammaan xalalka milixda-saldhigga (oo ay ku jiraan fuming nitric acid, fuming sulfuric acid), aan lagu dabaqi karin: aqua regia, cusbada ammonia, hydrogen peroxide, hydrochloric acid (> 15%). |
Nuxurka kore waxa loogu talagalay tixraac kaliya, fadlan tixraac imtixaanka dhabta ah. Dabcan, sidoo kale waad nala tashan kartaa. Waxaan ku siin doonaa xoogaa talooyin ah.
