HEDP Cas 2809-21-4 Acide ya Acide Monohydrate
1-Hydroxyethylidene-1,1-acide diphosphonique / HEDP CAS 2809-21-4
1-Hydroxyethylidene-1,1-Acide Diphosphonike (HEDP)
URUBANZA No: 2809-21-4
Inzira ya molekulari: C2H8O7P2
Koresha
HEDP ni ubwoko bwa cathodic corrosion inhibitor. Ugereranije na fosifike idafite ingufu, irashobora kongerwamo na sodium molybdate, silikatike, umunyu wa zinc hamwe na polymer hamwe cyane cyane nka inhibitor ya ruswa yangiza mugutunganya amazi akonje ya cyclicale, flash yamashanyarazi hamwe namazi yo kubira .Bishobora kandi gukoreshwa nkibikurikiranwa mubintu byogosha kandi bigoye hamwe nicyuma cya elegitoronike.
Ibiranga
HEDP irashobora kugabanuka kuri ion eshanu nziza cyangwa mbi hanyuma igashiramo ion ebyiri zifite agaciro mumazi. Rero bifata igipimo cyiza cyo kubuza ingaruka. Ibicuruzwa nibihamya ubushyuhe bwo hejuru, okiside hamwe nagaciro ka pH. Yerekana ingaruka nziza zo guhuza no gukemura ingaruka zingana mugihe ziyongereye hamwe nizindi mbogamizi za ruswa.

Ikoreshwa
HEDP irashobora kongerwamo aside hydroxylaectic, PAA, BTA, molybdate, copolymer, umunyu wa zinc, kugirango ikore organic-organic-alkali cyangwa fosifori nkeya ya zinc ishingiye kumiti yo gukoresha amazi kugirango ikoreshwe muburyo bwose bwamazi akonje ya cyclicale atandukanye nubwiza bwamazi. Igipimo muri rusange ni 2 ~ 10mg / L mugihe HEDP ikoreshwa wenyine.
Ububiko nububiko
250 kg ingoma ya plastike cyangwa 1250kg IBC, kugirango ibike mucyumba gikonje kandi gihumeka hamwe nigihe cyo kumara umwaka umwe.
Pls twandikire kugirango tubone COA na MSDS. Murakoze.
