wai HEDP 60% 1-Hydroxyethylidene-1,1-diphosphonic acid cas 2809-21-4 Etidronic acid monohydrate

Nā Hiʻohiʻona:
He mea pale i ka palaho o ka waikawa organophosphoric ʻo HEDP. Hiki iā ia ke chelate me Fe, Cu, a me Zn etc.
nā ion metala a hana i kahi hui paʻakikī paʻa.
Hiki iā ia ke hoʻoheheʻe i nā mea i hoʻoheheʻe ʻia ma luna o nā ʻili o kēia mau metala. Ma lalo o 250 ℃ hōʻike ʻo HEDP i ka unahi maikaʻi loa a me ka hiki ke pale i ka pala.
He kūpaʻa kemika maikaʻi ko HEDP ma lalo o ka waiwai pH kiʻekiʻe, paʻakikī ke hydrolyzed, a paʻakikī ke decompose ma lalo o nā kūlana mālamalama a me ka wela maʻamau. ʻOi aku ka maikaʻi o kona hoʻomanawanui ʻana i ka waikawa/alkali a me ka chlorine oxidation ma mua o nā waikawa organophosphoric ʻē aʻe (paʻakai).
Hiki i ka HEDP ke hana me nā ion metala i loko o ka ʻōnaehana wai e hana i ka paʻakikī chelating hexa-element, me ka ion calcium ma ke ʻano kūikawā. No laila, loaʻa iā HEDP nā hopena antiscale maikaʻi a me nā hopena paepae ʻike ʻia.
Ke kūkulu ʻia pū ʻia me nā kemika mālama wai ʻē aʻe, hōʻike ia i nā hopena synergistic maikaʻi.

He huahana maʻemaʻe kiʻekiʻe ka paʻa o HEDP, kūpono no ka hoʻohana ʻana i ka hoʻoilo a me nā ʻāpana hau.
He kūpono loa ia no ka hoʻohana ʻana ma ke ʻano he mea hoʻomaʻemaʻe i nā kahua uila a me nā mea hoʻohui i nā kemika o kēlā me kēia lā.

Nā noi:
Hoʻohana nui ʻia ʻo HEDP i loko o ka ʻōnaehana wai anuanu i loko o ka mana uila, ʻoihana kemika, metallurgy, mea hoʻomomona, a pēlā aku a hoʻohana nui ʻia e like me ka unahi a me ka mea hoʻōki i ka palaho o nā paila haʻahaʻa, ke kahua wai kahe, a me ka pipeline aila.

I ka ʻoihana māmā a me ka lole, hoʻohana ʻia ʻo HEDP ma ke ʻano he detergent no ka metala a me ka mea ʻole metala. I ka ʻoihana dyeing, hoʻohana ʻia ʻo HEDP ma ke ʻano he peroxide stabilizer a me ka dye-fixing agent; I ka electroplating non-cyanide, hoʻohana ʻia ʻo HEDP ma ke ʻano he chelating agent. ʻOi aku ka makemake ʻia o ka dosage o 1-10mg/L ma ke ʻano he scale inhibitor, 10-50mg/L ma ke ʻano he corrosion inhibitor, a me 1000-2000mg/L ma ke ʻano he detergent. ʻO ka maʻamau, hoʻohana pū ʻia ʻo HEDP me ka polycarboxylic acid.
