HEDP Cas 2809-21-4 ʻakika Etidronic Monohydrate
1-Hydroxyethylidene-1,1-diphosphonic acid / HEDP CAS 2809-21-4
1-Hydroxyethylidene-1,1-Diphosphonic Acid (HEDP)
Helu CAS: 2809-21-4
Formula Molekala: C2H8O7P2
Hoʻohana
ʻO HEDP kahi ʻano mea hoʻopale i ka palaho cathodic. Ke hoʻohālikelike ʻia me nā phosphates inorganic, hiki ke hoʻohui ʻia me ka sodium molybdate, silicate, zinc salt a me co-polymer ma ke ʻano he mea hoʻopale i ka palaho unahi i ka mālama ʻana i ka wai hoʻoluʻu cyclic, ka flash kahua aila a me ka wai paila. Hiki ke hoʻohana ʻia hoʻi ma ke ʻano he sequestrant i loko o ka detergent a me ka complexing agent a me ka metal scour i ka electroplating.
ʻAno
Hiki i ka HEDP ke hoʻokaʻawale i nā ion ʻelima maikaʻi a maikaʻi ʻole paha a hoʻopili i ka ion metala ʻelua-valent i loko o ka wai. No laila, lawe ia i kahi hopena pale unahi maikaʻi. He hōʻoia kēia huahana e kūʻē i ke kiʻekiʻe o ka mahana, ka oxidizing a me ka waiwai pH kiʻekiʻe. Hōʻike ia i ka hopena synergic kūpono a me ka hopena paepae hoʻonā i ka wā e hui pū ʻia me nā mea pale corrosion ʻē aʻe a me nā mea pale unahi.

Hoʻohana
Hiki ke hoʻohui ʻia ʻo HEDP me ka waikawa hydroxylaectic, PAA, BTA, molybdate, copolymer, paʻakai zinc, e hana i ka mea hoʻōla wai piha-organic-alkali a i ʻole ka mea hoʻoheheʻe zinc haʻahaʻa-phosphor e hoʻohana ʻia i nā ʻano ʻōnaehana wai hoʻoluʻu cyclic āpau ʻokoʻa mai ka maikaʻi o ka wai. ʻO ka nui maʻamau he 2 ~ 10mg / L ʻoiai e hoʻohana wale ʻia ʻo HEDP.
Pūʻolo a me ka Mālama ʻana
Pahu palaki 250kg a i ʻole 1250kg IBC, e mālama ʻia i loko o kahi lumi anuanu a me ka ea me ka manawa papa o hoʻokahi makahiki.
E ʻoluʻolu e hoʻokaʻaʻike mai iā mākou e kiʻi i ka COA a me ka MSDS. Mahalo.
