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)
Nhamba yeCAS: 2809-21-4
Fomura yeMolecular: C2H8O7P2
Shandisa
HEDP imhando ye cathodic corrosion inhibitor. Kana ichienzaniswa ne inorganic phosphates, inogona kuwedzerwa ne sodium molybdate, silicate, zinc salt uye co-polymer kunyanya se scale corrosion inhibitor mukurapa cyclic cooling water, oil field flash uye boiler water. Inogona zvakare kushandiswa se sequestrant mu detergent uye complexing agent uye metal scour mu electroplating.
Hunhu
HEDP inogona kubva pakubatanidzwa kuita maion mashanu akanaka kana asina kunaka yobva yaburitsa maion maviri esimbi mumvura. Saka inotora mhedzisiro yakanaka yekudzivirira scale. Chigadzirwa ichi chinodzivirira kupisa kwakanyanya, oxidizing uye pH yakakwira. Chinoratidza mhedzisiro yakakwana ye synergic uye mhedzisiro yekugadzirisa threshold ukuwo ichisanganiswa nezvimwe zvinodzivirira corrosion uye zvinodzivirira scale.

Kushandiswa
HEDP inogona kusanganiswa ne hydroxylaectic acid, PAA, BTA, molybdate, copolymer, zinc salt, kugadzira whole-organic-alkali kana low-phosphorus zinc-based agent yekurapa mvura inoshandiswa mumhando dzese dzemvura dzinotonhorera dzakasiyana nedzemhando yemvura. Dose inowanzo kuve 2~10mg/L ukuwo HEDP ichishandiswa yega.
Pakeji uye Kuchengeta
Dhiramu repurasitiki re250kg kana 1250kg IBC, rinofanira kuchengetwa muimba inotonhorera uye ine mhepo ine nguva yegore rimwe chete.
