Mea Hana Hana HEDP mai Kina CAS:2809-21-4 me ke Kiʻekiʻe
Waiwai
ʻO ka HEDP kahi mea hoʻopaneʻe corrosion acid organophosphoric. Hiki iā ia ke chelate me nā ion Fe, Cu, a me Zn e hana i nā pūhui chelating paʻa. Hiki iā ia ke hoʻoheheʻe i nā mea oxidized ma luna o kēia mau metala.
Hōʻike ka HEDP i ka pālākiō maikaʻi loa a me nā hopena inhibition corrosion ma lalo o ka mahana o 250°C.
He paʻa kemika maikaʻi ka HEDP ma lalo o ka waiwai PH kiʻekiʻe, paʻakikī ke hoʻoheheʻe ʻia, a paʻakikī hoʻi e hoʻoheheʻe ʻia ma lalo o nā kūlana māmā a me ka wela. ʻOi aku ka maikaʻi o kona ʻakika/alkali a me ka chlorine oxidation tolerance ma mua o nā ʻakika organophosphoric ʻē aʻe (paʻakai).
Hiki i ka HEDP ke hana me nā iona metala i loko o ka ʻōnaehana wai e hana i ka paʻakikī chelating hexa-element, me ka ion calcium.
No laila, loaʻa i ka HEDP nā hopena antiscale maikaʻi a ʻike ʻia. Ke kūkulu pū ʻia me nā kemika mālama wai ʻē aʻe, hōʻike ia i nā hopena synergistic maikaʻi.

Hoohana Huahana
1. HEDP (Cas No 2809-21-4) Hoʻohana ʻia ʻo Corrosion Inhibitor e like me ka unahi a me ka corrosion inhibition i ka circulatingcool water system, oil field and low-pressure boilers i loko o nā māla e like me ka mana uila, ʻoihana kemika, metallurgy, fertilizer, etc.
2. Ma ka ʻoihana ulana māmā, HEDP (Cas No 2809-21-4) Hoʻohana ʻia ka Corrosion Inhibitor e like me ka mea holoi no ka metala a me ka nonmetal.
3. I loko o ka ʻoihana kala, HEDP (Cas No 2809-21-4) Hoʻohana ʻia ʻo Corrosion Inhibitor ma ke ʻano he peroxide stabilizer a me ka mea hoʻoponopono wai.
4. I ka non-cyanide electroplating, HEDP (Cas No 2809-21-4) Corrosion Inhibitor ua hoʻohana ʻia ma ke ʻano he chelating agent. ʻO ke ʻano o 1-10mg / L ua makemake ʻia e like me ka mea paʻa paona, 10-50mg / L e like me ka corrosion inhibitor, a 1000-2000mg/L e like me ka mea holoi.
ʻO ka maʻamau, hoʻohana pū ʻia ka HEDP (Cas No 2809-21-4) Corrosion Inhibitor me ka polycarboxylic acid.
Pūʻolo a me ka waiho ʻana
ʻO ATMP wai: 200L pahu pahu, IBC (1000L), koi a nā mea kūʻai aku.
Mālama ʻia no 12 mahina ma kahi lumi malu a me kahi maloʻo.
