mmiri mmiri HEDP 60% 1-Hydroxyethylidene-1,1-diphosphonic acid cas 2809-21-4 Etidonic acid monohydrate

Atụmatụ:
HEDP bụ ihe mgbochi corrosion organophosphoric acid. Ọ nwere ike chelate na Fe, Cu, na Zn wdg.
metal ion na-etolite anụ mgbagwoju ogige.
Ọ nwere ike igbari ihe oxidized n'elu ọla ndị a. N'okpuru 250 ℃ HEDP na-egosi ọkwa dị mma na ikike mgbochi corrosion.
HEDP nwere ezigbo nkwụsi ike nke kemịkalụ n'okpuru uru pH dị elu, siri ike ka ọ bụrụ hydrolyzed, na ike ire ere n'okpuru ọkụ nkịtị na ọnọdụ okpomọkụ. Ya acid/alkali na chlorine oxidation ndidi dị mma karịa nke ndị ọzọ organophosphoric acid (nnu).
HEDP nwere ike meghachi omume na ion metal na sistemu mmiri iji mepụta ogige hexa-element chelating complex, yana calcium ion karịsịa. Ya mere, HEDP nwere ezigbo mgbochi na mmetụta ọnụ ụzọ a na-ahụ anya.
Mgbe ejikọtara ya na kemịkalụ ọgwụgwọ mmiri ndị ọzọ, ọ na-egosi mmetụta synergistic dị mma.

Ihe siri ike nke HEDP bụ ngwaahịa dị ọcha dị elu, kwesịrị ekwesị maka iji n'oge oyi na mpaghara oyi.
Ọ dabara nke ọma iji dị ka onye na-ehicha ihe na mpaghara eletrọnịkị yana ihe mgbakwunye na kemịkalụ kwa ụbọchị.

Ngwa:
A na-ejikarị HEDP na-ekesa usoro mmiri dị jụụ nke ike eletriki, ụlọ ọrụ kemịkalụ, metallurgy, fatịlaịza, wdg na ọtụtụ ebe a na-eji dị ka ọnụ ọgụgụ na corrosion inhibitor nke obere ọkụ ọkụ, ubi mmiri iju mmiri, mmanụ pipeline.

N'ime ụlọ ọrụ ọkụ & textile, a na-eji HEDP mee ihe dị ka ncha maka ọla na igwe anaghị agba nchara. Na ụlọ ọrụ ịcha akwa, a na-eji HEDP dị ka onye na-edozi peroxide na onye na-edozi ihe; Na electroplating na-abụghị cyanide, a na-eji HEDP dị ka onye na-ahụ maka chelating. A na-ahọrọ usoro onunu ogwu nke 1-10mg/L dị ka onye na-egbochi ọnụ ọgụgụ, 10-50mg/L dị ka ihe mgbochi corrosion, na 1000-2000mg/L dị ka ncha. Ọtụtụ mgbe, a na-eji HEDP na polycarboxylic acid.
