Electromagnetic flowmeter ndi chida chomwe chimagwiritsa ntchito mfundo ya electromagnetic induction kuyeza kutuluka kwamadzimadzimadzimadzi potengera mphamvu yamagetsi yomwe imapangitsidwa pomwe madzimadzi amadutsa pamagetsi akunja.
Ndiye momwe mungasankhire akalowa mkati ndi electrode chuma?
Lining Material Selection
■ Neoprene (CR):
Polima wopangidwa ndi emulsion polymerization wa chloroprene monomer. Molekyu ya mphira ili ndi maatomu a chlorine, kotero poyerekeza ndi mphira wina wofunikira: Ili ndi anti-oxidation, anti-ozone, yosayaka, yozimitsa yokha pambuyo pa moto, kukana mafuta, kukana zosungunulira, asidi ndi alkali kukana, ndi kukalamba. ndi kukana gasi. Kukhazikika kwabwino komanso zabwino zina.
✔ Ndi oyenera otaya muyeso wa madzi apampopi, madzi mafakitale, madzi a m'nyanja ndi zina TV.
■ Rabala ya polyurethane (PU):
Imapangidwa ndi polyester (kapena polyether) ndi diisocyanamide lipid pawiri. Lili ndi ubwino wa kuuma kwakukulu, mphamvu zabwino, kusungunuka kwakukulu, kukana kuvala kwapamwamba, kukana misozi, kukana kukalamba, kukana kwa ozoni, kukana kwa ma radiation ndi kuyendetsa bwino kwa magetsi.
✔ Ndikoyenera kuyeza kuyeza kwa slurry media monga zamkati ndi zamkati za ore.
■Polytetrafluoroethylene (P4-PTFE)
Ndi polima yokonzedwa ndi polymerization wa tetrafluoroethylene monga monoma. Waxy woyera, translucent, kutentha kukana, kukana kuzizira, angagwiritsidwe ntchito mu -180 ~ 260 ° C nthawi yaitali. Nkhaniyi ali ndi makhalidwe a asidi ndi alkali kukana, kukana zosungunulira zosiyanasiyana organic, kukana otentha hydrochloric acid, asidi sulfuric, aqua regia, anaikira zamchere dzimbiri.
✔ Angagwiritsidwe ntchito zikuwononga asidi ndi alkali mchere madzi.
■Polyperfluoroethylene propylene (F46-FEP)
Ili ndi kukhazikika kwamphamvu kwamankhwala komanso kukana kwambiri kwa radiation, komanso kusayaka, magetsi abwino komanso makina. Mankhwala ake amafanana ndi polytetrafluoroethylene, yokhala ndi mphamvu yopondereza komanso yolimba kwambiri kuposa polytetrafluoroethylene.
✔ Angagwiritsidwe ntchito zikuwononga asidi ndi alkali mchere madzi.
■Copolymer ya tetrafluoroethylene ndi perfluorocarbon kudzera pa vinyl ether (PFA)
The akalowa zinthu maginito flowmeter ali ofanana mankhwala katundu monga F46 ndi bwino kumakoka mphamvu kuposa F46.
✔Angagwiritsidwe ntchito zikuwononga asidi ndi alkali mchere madzi.
Electrode Material Selection
| 316l ndi | Ndi oyenera zinyalala m'nyumba, zimbudzi mafakitale, madzi chitsime, zimbudzi m'tawuni, etc., ndi ofooka zikuwononga acid-mchere njira mchere. |
| Hastelloy (HB) | Oyenera ku non-oxidizing zidulo monga hydrochloric acid (concentration zosakwana 10%). Sodium hydroxide (concentration zosakwana 50%) sodium hydroxide alkali solution ya ndende zonse. Phosphoric acid kapena organic acid, etc., koma asidi wa nitric sioyenera. |
| Hastelloy (HC) | Kusakaniza kwa asidi ndi njira yosakaniza ya chromic acid ndi sulfuric acid. Oxidizing salt monga Fe +++, Cu ++, madzi a m'nyanja, phosphoric acid, organic acids, etc., koma osati oyenera hydrochloric acid. |
| Titaniyamu (Ti) | Amagwiritsidwa ntchito ku ma chloride (monga sodium kolorayidi/magnesium kolorayidi/calcium kolorayidi/ferric chloride/ammonium kolorayidi/aluminium kolorayidi, etc.), mchere (monga mchere wa sodium, ammonium salt, hypofluorite, potaziyamu mchere, madzi a m'nyanja) , nitric acid (koma osaphatikizapo fuming nitric acid), alkali ndi ndende ≤50% kutentha kwa firiji (potaziyamu hydroxide, sodium hydroxide, barium hydroxide, etc.) koma osagwira ntchito: hydrochloric acid, sulfuric acid, phosphoric acid, hydrofluoric acid, etc. |
| Tantalum electrode (Ta) | Oyenera hydrochloric acid (concentration ≤ 40%), kuchepetsa sulfuric acid ndi concentrated sulfuric acid (kupatula fuming nitric acid). Amagwiritsidwa ntchito ku chlorine dioxide, ferric chloride, hypofluorous acid, hydrobromic acid, sodium cyanide, lead acetate, nitric acid (kuphatikiza fuming nitric acid) ndi aqua regia yomwe kutentha kwake kumakhala kotsika kuposa 80 ° C. Koma ma elekitirodi izi si oyenera alkali, asidi hydrofluoric, madzi. |
| Platinum electrode (Pt) | Imagwira pafupifupi mitundu yonse ya mchere wa asidi (kuphatikiza nitric acid, fuming sulfuric acid), osagwira ntchito ku: aqua regia, ammonia mchere, hydrogen peroxide, hydrochloric acid (> 15%). |
Zomwe zili pamwambazi ndizongogwiritsa ntchito, chonde onani mayeso enieni. Inde, mungathenso kutifunsa. Tikupatsirani malingaliro.
Kampani yathu imapanganso zida zosinthira zida zogwirizana, kuphatikiza maelekitirodi, ma diaphragms achitsulo, mphete zoyambira, ma diaphragm flanges, ndi zina zambiri.
Chonde dinani kuti muwone zinthu zogwirizana, zikomo.(Whatsapp/Wechat: +86 156 1977 8518)
