Khetho ea Lisebelisoa tsa Lesela
■ Neoprene (CR):
Polymer e entsoeng ka emulsion polymerization ea chloroprene monomer. Molek'hule ena ea rabara e na le liathomo tsa chlorine, kahoo ha e bapisoa le rabara e meng e akaretsang: E na le anti-oxidation e ntle haholo, anti-ozone, e sa cheng, e itimang ka mor'a mollo, ho hanyetsa oli, ho hanyetsa solvent, acid le alkali resistance, le botsofali. le ho hanyetsa khase. Tightness e ntle le melemo e meng.
✔ E loketse tekanyo ea phallo ea metsi a pompo, metsi a indasteri, metsi a leoatle le mecha e meng ea litaba.
■ Rabara ea polyurethane (PU):
E entsoe ka polyester (kapa polyether) le motsoako oa diisocyanamide lipid. E na le melemo ea boima bo phahameng, matla a matle, elasticity e phahameng, khanyetso e phahameng ea ho roala, ho hanyetsa meokho, ho hanyetsa botsofali, ho hanyetsa ozone, ho hanyetsa mahlaseli le motlakase o motle oa motlakase.
✔ E loketse tekanyo ea phallo ea li-slurry media joalo ka pulp le ore pulp.
■Polytetrafluoroethylene (P4-PTFE)
Ke polymer e entsoeng ka polymerization ea tetrafluoroethylene e le monoma. Waxy e tšoeu, e khanyang, e hanyetsa mocheso, ho hanyetsa serame, e ka sebelisoa ho -180 ~ 260 ° C nako e telele. Boitsebiso bona bo na le litšoaneleho tsa ho hanyetsa acid le alkali, ho hanyetsa lihlahisoa tse fapaneng tsa tlhaho, ho hanyetsa ho belisoa ha hydrochloric acid, sulfuric acid, aqua regia, concentrated alkali corrosion.
✔ E ka sebelisoa bakeng sa acid e senyang le metsi a letsoai a alkali.
■Polyperfluoroethylene propylene (F46-FEP)
E na le botsitso bo botle ba lik'hemik'hale le ho hanyetsa mahlaseli a ikhethang, hammoho le ho se chese, lisebelisoa tse ntle tsa motlakase le tsa mechine. Lik'hemik'hale tsa eona tsa lik'hemik'hale li lekana le polytetrafluoroethylene, e nang le matla a matla a ho hatella le a thata ho feta polytetrafluoroethylene.
✔ E ka sebelisoa bakeng sa acid e senyang le metsi a letsoai a alkali.
■Copolymer ea tetrafluoroethylene le perfluorocarbon ka vinyl ether (PFA)
Thepa ea lesela bakeng sa phallo ea motlakase ea motlakase e na le lik'hemik'hale tse tšoanang le tsa F46 le matla a matle ho feta F46.
✔E ka sebelisoa bakeng sa acid e senyang le metsi a letsoai a alkali.
Khetho ea Lintho tsa Electrode
| 316L | E loketse likhoerekhoere tsa malapeng, likhoerekhoere tsa indasteri, metsi a seliba, likhoerekhoere tsa litoropo, joalo-joalo, le tharollo e fokolang ea letsoai la acid-base. |
| Hastelloy (HB) | E loketse li-non-oxidizing acids tse kang hydrochloric acid (concentration e ka tlase ho 10%). Sodium hydroxide (concentration ka tlase ho 50%) sodium hydroxide alkali solution ea metsoako eohle. Phosphoric acid kapa organic acid, joalo-joalo, empa asiti ea nitric ha ea lokela. |
| Hastelloy (HC) | Asiti e tsoakiloeng le tharollo e tsoakiloeng ea chromic acid le sulfuric acid. Matsoai a oxidizing a kang Fe +++, Cu ++, metsi a leoatle, phosphoric acid, organic acid, joalo-joalo, empa ha a tšoanelehe bakeng sa hydrochloric acid. |
| Titanium (Ti) | E sebetsa ho chloride (joalo ka sodium chloride/magnesium chloride/calcium chloride/ferric chloride/ammonium chloride/aluminium chloride, joalo-joalo), letsoai (joalo ka letsoai la sodium, letsoai la ammonium, hypofluorite, letsoai la potasiamo, metsi a leoatle) , nitric acid (empa e sa kenyelletseng fuming nitric acid), alkalis e nang le mahloriso ≤50% mocheso oa kamore (potassium hydroxide, sodium hydroxide, barium hydroxide, joalo-joalo) empa ha e sebetse ho: hydrochloric acid, sulfuric acid, phosphoric acid, hydrofluoric acid, joalo-joalo. |
| Tantalum electrode (Ta) | E loketse hydrochloric acid (concentration ≤ 40%), hlapolla sulfuric acid le concentrated sulfuric acid (ntle le fuming nitric acid). E sebetsa ho chlorine dioxide, ferric chloride, hypofluorous acid, hydrobromic acid, sodium cyanide, lead acetate, nitric acid (ho kenyeletsoa fuming nitric acid) le aqua regia eo mocheso oa eona o leng tlase ho 80°C. Empa thepa ena ea electrode ha e loketse alkali, hydrofluoric acid, metsi. |
| Platinum electrode (Pt) | E sebetsa hoo e batlang e le litharollo tsohle tsa letsoai tse nang le acid-base (ho kenyeletsoa acid e fuming nitric, fuming sulfuric acid), ha e sebetse ho: aqua regia, letsoai la ammonia, hydrogen peroxide, concentrated hydrochloric acid (> 15%). |
Litaba tse ka holimo ke tsa litšupiso feela, ka kopo sheba tlhahlobo ea 'nete. Ha e le hantle, u ka boela ua re botsa. Re tla u fa litlhahiso tse ling.
Khamphani ea rona e boetse e hlahisa likarolo tsa lisebelisoa tse amanang le tsona, ho kenyelletsa li-electrode, li-diaphragm tsa tšepe, mehele ea fatše, li-diaphragm flanges, joalo-joalo.
Ka kopo, tobetsa ho sheba lihlahisoa tse amanang, kea leboha.(Whatsapp/Wechat: +86 156 1977 8518)
