Electromagnetic flowmeter yog ib qho cuab yeej uas siv lub hauv paus ntsiab lus ntawm electromagnetic induction los ntsuas qhov ntws ntawm cov kua dej conductive raws li lub zog electromotive tshwm sim thaum cov kua dej conductive hla dhau lub teb magnetic sab nraud.
Yog li yuav ua li cas xaiv cov khoom siv sab hauv thiab cov khoom siv electrode?
Kev Xaiv Khoom Siv Hauv Sab Hauv
■ Neoprene (CR):
Ib qho polymer uas tsim los ntawm kev sib xyaw ua ke ntawm chloroprene monomer. Cov roj hmab no muaj cov chlorine atoms, yog li piv rau lwm cov roj hmab dav dav: Nws muaj kev tiv thaiv zoo heev rau kev tiv thaiv oxidation, tiv thaiv ozone, tsis kub hnyiab, tua nws tus kheej tom qab hluav taws, tiv thaiv roj, tiv thaiv cov kuab tshuaj, tiv thaiv acid thiab alkali, thiab tiv thaiv kev laus thiab roj. Zoo nruj thiab lwm yam zoo.
✔ Nws yog qhov tsim nyog rau kev ntsuas dej ntws ntawm cov kais dej, dej lag luam, dej hiav txwv thiab lwm yam xov xwm.
■ Roj hmab Polyurethane (PU):
Nws yog polymerized los ntawm polyester (lossis polyether) thiab diisocyanamide lipid compound. Nws muaj qhov zoo ntawm kev siab tawv, lub zog zoo, siab elasticity, siab hnav tsis kam, tsim kua muag tsis kam, laus tsis kam, ozone tsis kam, hluav taws xob tsis kam thiab hluav taws xob zoo conductivity.
✔ Nws yog qhov tsim nyog rau kev ntsuas ntws ntawm cov khoom siv slurry xws li pulp thiab ore pulp.
■Polytetrafluoroethylene (P4-PTFE)
Nws yog ib qho polymer uas tau npaj los ntawm kev sib xyaw ua ke ntawm tetrafluoroethylene ua ib qho monomer. Dawb waxy, translucent, tiv taus kub, tiv taus txias, tuaj yeem siv tau ntev hauv -180 ~ 260 ° C. Cov khoom no muaj cov yam ntxwv ntawm kev tiv taus kua qaub thiab alkali, tiv taus ntau yam organic solvents, tiv taus boiling hydrochloric acid, sulfuric acid, aqua regia, thiab concentrated alkali corrosion.
✔ Yuav siv tau rau cov kua qaub corrosive thiab alkali ntsev kua.
■Polyperfluoroethylene propylene (F46-FEP)
Nws muaj kev ruaj khov tshuaj lom neeg zoo heev thiab tiv taus hluav taws xob zoo heev, nrog rau tsis kub hnyiab, hluav taws xob zoo thiab khoom siv kho tshuab. Nws cov khoom siv tshuaj lom neeg zoo ib yam li polytetrafluoroethylene, nrog lub zog compressive thiab tensile zoo dua li polytetrafluoroethylene.
✔ Yuav siv tau rau cov kua qaub corrosive thiab alkali ntsev kua.
■Copolymer ntawm tetrafluoroethylene thiab perfluorocarbon ntawm vinyl ether (PFA)
Cov khoom siv hauv pem teb rau electromagnetic flowmeter muaj cov khoom siv tshuaj lom neeg zoo ib yam li F46 thiab lub zog tensile zoo dua li F46.
✔Yuav siv tau rau cov kua qaub corrosive thiab alkali ntsev kua.
Kev Xaiv Khoom Siv Hluav Taws Xob
| 316L | Nws yog qhov tsim nyog rau cov dej phwj hauv tsev, cov dej phwj hauv kev lag luam, dej qhov dej, cov dej phwj hauv nroog, thiab lwm yam, thiab cov kua qaub-raws ntsev uas tsis muaj zog corrosive. |
| Hastelloy (HB) | Haum rau cov kua qaub uas tsis yog oxidizing xws li hydrochloric acid (concentration tsawg dua 10%). Sodium hydroxide (concentration tsawg dua 50%) sodium hydroxide alkali kua ntawm txhua qhov concentration. Phosphoric acid lossis organic acid, thiab lwm yam, tab sis nitric acid tsis haum. |
| Hastelloy (HC) | Cov kua qaub sib xyaw thiab cov kua sib xyaw ntawm chromic acid thiab sulfuric acid. Cov ntsev oxidizing xws li Fe+++, Cu++, dej hiav txwv, phosphoric acid, organic acids, thiab lwm yam, tab sis tsis haum rau hydrochloric acid. |
| Titanium (Ti) | Siv tau rau cov chlorides (xws li sodium chloride/magnesium chloride/calcium chloride/ferric chloride/ammonium chloride/aluminium chloride, thiab lwm yam), ntsev (xws li sodium ntsev, ammonium ntsev, hypofluorite, potassium ntsev, dej hiav txwv), nitric acid (tab sis tsis suav nrog fuming nitric acid), alkalis nrog concentration ≤50% ntawm chav tsev kub (potassium hydroxide, sodium hydroxide, barium hydroxide, thiab lwm yam) tab sis tsis siv tau rau: hydrochloric acid, sulfuric acid, phosphoric acid, hydrofluoric acid, thiab lwm yam. |
| Tantalum electrode (Ta) | Haum rau hydrochloric acid (concentration ≤ 40%), dilute sulfuric acid thiab concentrated sulfuric acid (tsis suav nrog fuming nitric acid). Siv tau rau chlorine dioxide, ferric chloride, hypofluorous acid, hydrobromic acid, sodium cyanide, lead acetate, nitric acid (suav nrog fuming nitric acid) thiab aqua regia uas qhov kub qis dua 80 ° C. Tab sis cov khoom siv electrode no tsis haum rau alkali, hydrofluoric acid, dej. |
