HEDP

Hydroxyethylidene diphosphonic acid (HEDP) ke sekala le thibelo ya mafome e thehilweng hodima phosphonic acid ya tlhaho e etsang di-complex tse tsitsitseng tse nang le di-ion tse fapaneng tsa tshepe, tse kang tshepe, koporo le zinki, mme e qhibilihisa di-oxide hodima bokahodimo ba tshepe.

E ntse e sebetsa hantle ho thibeleng ho bola le ho thehwa ha sekala esita le ka mocheso wa 250°C, e dula e tsitsitse maemong a phahameng a pH, mme e hanela hydrolysis. HEDP e bontsha kganyetso e betere ho di-acid, di-alkali le oxidation ya chlorine ho feta di-acid tse ding tsa organic phosphonic (le matswai a tsona).

Metsi:

● Kalafo ea metsi a pholileng a potolohang indastering: HEDP e thibela ka katleho ho thehoa ha sekala, e sireletsa litsamaiso tsa metsi a pholileng a potolohang indastering ho sekala le mafome. E theha metsoako e tsitsitseng ka li-ion tse fapaneng tsa tšepe, ho kenyeletsoa tšepe, koporo, aluminium le zinki, e leng se etsang hore e lokele ho tlosa mafome le mesaletsa ea letsoai e sa pheleng ho tsoa liboiler le liphaepheng.

● Tšireletso ea Boiler le Mocheso: Jwalo ka mothibi oa sekala le mothibi oa mafome, HEDP e sebelisetsoa ho sireletsa liboiler le li-heat exchanger ka ho thibela ho hola ka hare le mafome, ka hona e eketsa bophelo ba ts'ebeletso ea lisebelisoa.

● Moemeli oa ho rarahana bakeng sa ho rarahana ntle le cyanide: Indastering ea ho rarahana, HEDP e sebetsa e le moemeli oa ho rarahana bakeng sa ho rarahana ntle le cyanide, e leng se ntlafatsang katleho ea ho rarahana le boleng ba sehlahisoa.

● Moemeli oa ho Hloekisa bakeng sa Tšepe le Tse seng Tšepe: HEDP e ka sebelisoa e le moemeli oa ho hloekisa bakeng sa tšepe le tse seng tšepe, e tlosa litšila le litšila holim'a thepa e fapaneng.

● Sehatsetsi le Sekoahelo Indastering ea ho Daea: Indastering ea ho daea, HEDP e sebetsa e le sehatsetsi le sekoahelo sa peroxide, e ntlafatsang boleng le botsitso ba sehlahisoa.

E tiileng:

● Setlatsetso bakeng sa Lik'hemik'hale tsa Lapeng: Ka lebaka la bohloeki ba eona bo phahameng, HEDP e ka boela ea sebelisoa e le tlatsetso lik'hemik'haleng tsa lapeng, tse kang litlolo le sesepa, ho fana ka boiphihlelo bo betere ba mosebelisi.

● Lisebelisoa tsa ho hloekisa indastering ea lisebelisoa tsa elektroniki: Indastering ea lisebelisoa tsa elektroniki, HEDP e sebelisoa ho hloekisa likarolo le lisebelisoa tse nepahetseng, ho ntlafatsa ts'ebetso le botsitso ba lisebelisoa.

● Lisebelisoa tsa ho jara thepa lefapheng la bongaka le tlhokomelo ea bophelo: HEDP e sebetsa e le sesebelisoa sa ho jara lintho tse ntšang mahlaseli a kotsi 'me e sebelisoa haholo ho hlahlobeng le ho phekola mafu a qoqotho le a liphio.

Jwalo ka sekala se thibelang, HEDP hangata e sebediswa maemong a 1-10 mg/L; e le sethibela-mafome, ho 10-50 mg/L; mme e le sehlatswa, ho 1,000-2,000 mg/L. Hangata e sebediswa mmoho le dithibela-mafome tse thehilweng ho polycarboxylic acid le dispersants.
