HEDP Cas 2809-21-4 Etidronic Acid Monohydrate
1-Hydroxyethylidene-1,1-diphosphonic acid / HEDP CAS 2809-21-4
1-Hydroxyethylidene-1,1-Diphosphonic Acid (HEDP)
No CAS: 2809-21-4
Ke Kumu Molekala: C2H8O7P2
Hoʻohana
ʻO HEDP kahi ʻano o ka cathodic corrosion inhibitor. Hoʻohālikelike ʻia me nā phosphates inorganic, hiki ke hoʻohui ʻia me ka sodium molybdate, silicate, zinc paʻakai a me ka co-polymer ma ke ʻano he mea hoʻopaʻapaʻa corrosion pālākiō i ka mālama ʻana i ka wai hoʻoheheʻe cyclic, ka ʻaila ʻaila a me ka wai paila.
Ke ano
Hiki i ka HEDP ke hoʻopaneʻe i ʻelima mau iona maikaʻi a i ʻole ʻino a chelate i ka iona metala ʻelua-valent i loko o ka wai. No laila, pono e loaʻa kahi hopena maikaʻi ʻole. He mea hōʻoia kēia huahana e kūʻē i ka wela kiʻekiʻe, oxidizing a me ka waiwai pH kiʻekiʻe. Hōʻike ia i ka hopena synergic maikaʻi loa a me ka hoʻoponopono ʻana i ka hopena paepae ʻoiai e hui pū ʻia me nā mea hoʻopiʻi corrosion a me nā mea paʻi paona.

Hoʻohana
Hiki ke hoʻohui ʻia ʻo HEDP me ka waika hydroxylaectic, PAA, BTA, molybdate, copolymer, zinc paʻakai, e hana i ka mea hoʻohana i ka wai hoʻomaʻamaʻa cyclic holoʻokoʻa mai ka maikaʻi o ka wai. ʻO ka maʻamau he 2 ~ 10mg / L a hoʻohana wale ʻia ʻo HEDP.
Pūʻolo a me ka waiho ʻana
250kg pahu pahu a i ʻole 1250kg IBC, e mālama ʻia i loko o kahi lumi anuanu a me ka manawa o hoʻokahi makahiki.
E leka uila mai iā mākou e kiʻi iā COA a me MSDS. Mahalo.
