Etidronic acid monohydrate
Nā kikoʻī huahana:
Inoa Huahana: pauka HEDP 90%
Nā inoa'ē aʻe: 1-Hydroxyethylidene-1,1-diphosphonic acid
Helu CAS: 2809-21-4
Ke Kumu Molekala: C2H8O7P2
Nānā: ka pauka keʻokeʻo
Hoʻohana: Hoʻoponopono Wai
Maʻemaʻe: 90% min
Nā noi:
Hoʻohana ʻia ʻo 1.HEDP e like me ka unahi a me ka corrosion inhibition i ke kahe ʻana i ka ʻōnaehana wai anuanu, ka ʻaila ʻaila a me nā boilers haʻahaʻa haʻahaʻa i nā kula e like me ka mana uila, ʻoihana kemika, metallurgy, fertilizer, etc.
2.Ma ka ʻoihana ulana māmā, hoʻohana ʻia ʻo HEDP ma ke ʻano he mea holoi no ka metala a me ka nonmetal. I ka ʻoihana kala, hoʻohana ʻia ʻo HEDP ma ke ʻano he peroxide stabilizer a me ka mea hoʻopaʻa wai;
3.In non-cyanide electroplating, hoʻohana ʻia ʻo HEDP ma ke ʻano he chelating agent. ʻO ke ʻano o ka 1-10mg/L ʻoi aku ka maikaʻi ma ke ʻano he mea hoʻopale unahi, 10-50mg/L ma ke ʻano o ka corrosion inhibitor, a me 1000-2000mg/L ma ke ʻano he mea holoi.
4. ʻO ka maʻamau, hoʻohana pū ʻia ʻo HEDP me ka polycarboxylic acid.
