pauka HEDP 90% 1-Hydroxyethylidene-1,1-diphosphonic acid cas 2809-21-4
ʻAkika Etidronic monohydrate
Nā kikoʻī huahana:
Inoa Huahana: pauka HEDP 90%
Nā inoa ʻē aʻe: 1-Hydroxyethylidene-1,1-diphosphonic acid
Helu CAS: 2809-21-4
Formula Molekala: C2H8O7P2
ʻAno: pauka keʻokeʻo
Noi: Hoʻōla wai
Maʻemaʻe: 90% min
Nā noi:
1. Hoʻohana ʻia ʻo HEDP e like me ka unahi a me ka pale ʻana i ka palaho i ka ʻōnaehana wai anuanu e kaapuni ana, ke kahua aila a me nā paila haʻahaʻa haʻahaʻa ma nā kahua e like me ka mana uila, ka ʻoihana kemika, ka metallurgy, ka mea hoʻoulu, a pēlā aku.
2. I ka ʻoihana ulana māmā, hoʻohana ʻia ʻo HEDP ma ke ʻano he mea holoi no ka metala a me ka mea ʻole metala. I ka ʻoihana hoʻoluʻu, hoʻohana ʻia ʻo HEDP ma ke ʻano he mea hoʻopaʻa peroxide a me ka mea hoʻopaʻa dye;
3. I ka electroplating ʻole-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 mea hoʻopale unahi, 10-50mg/L ma ke ʻano he mea hoʻopale corrosion, a me 1000-2000mg/L ma ke ʻano he detergent.
4. ʻO ka maʻamau, hoʻohana pū ʻia ʻo HEDP me ka waikawa polycarboxylic.
