Umusaruro wuzuye ni kristu y'umweru. Umusaruro w'inganda nta ibara cyangwa umuhondo woroshye ubonerana. Urashongesha mu mazi byoroshye kandi ushongesha muri methanol na ethanol. Aside ya Hydroxyethylidene diphosphonic ni igikoresho fatizo cy'imiti kandi gikunze gukoreshwa mu gusukura amazi mu nganda, mu gusukura mu ngo no mu bikoresho byo kwiyitaho.

Imikoreshereze
Iki gicuruzwa ni cyo gikoresho cy’ingenzi gikoreshwa mu gushushanya amashanyarazi adafite cyanide. Iyo cyakozwe mu buryo bwa electroplating y’umuringa udafite cyanide, kiba gifite imbaraga zo gufatanya neza iyo gishushanyije icyuma cy’umuringa ku cyuma cya sodium. Igipfundikizo kiba cyoroshye kandi gifite urumuri rwiza. Muri rusange, ingano y’igicuruzwa gifite ingano ya 60% ni 100 - 120 ml / L. Igipimo cya sulfate y’umuringa ni 15 - 20 g / L. Byongeye kandi, mbere yo gushushanya amashanyarazi, shyira ibice bya plating mu gisubizo cya 1% - 2% cy’iki gicuruzwa kugira ngo ibice bya plating bihinduke imiterere. Gushushanya amashanyarazi nyuma y’iki gikorwa bishobora kunoza kurushaho ingaruka. Aside diphosphonic ya Hydroxyethylidene (HEDP) ni ubwoko bushya bw’ibikoresho bya electroplating bidafite chlorine. Bikoreshwa nk’ikintu cy’ingenzi mu kubungabunga ubuziranenge bw’amazi mu buryo bw’amazi akonje azenguruka, bikagira uruhare mu gukumira ingese no gukumira ubukana bw’ibipimo. Iki gicuruzwa ni kimwe mu bikoresho bivura aside polyphosphonic y’umwimerere. Hariho kandi n'ubundi bwoko bw'ibicuruzwa nk'ibi bikorerwa mu Bushinwa, nka aside amino trimethylene phosphonic (ATMP): [CH2PO(OH)2]3N, na ethylenediamine tetra (methylene phosphonic acid) (EDTMP), nibindi. Aside polyphosphonic organic yakozwe mu mpera za 1960 kandi yamenyekanye ahagana mu myaka ya 1970. Kuvuka kw'ubu bwoko bw'ibikoreshwa mu gutunganya amazi byatumye habaho ikoranabuhanga rigezweho mu gutunganya amazi. Ugereranyije na polyphosphates inorganic, aside polyphosphonic organic ifite ubushobozi bwo kuguma mu bintu bya shimi, ntibyoroshye kuyikoresha, ishobora kwihanganira ubushyuhe bwinshi, ikenera doze nto y'ibikoreshwa, kandi ifite imiterere yo kwangirika no gukumira ubushyuhe. Ni ubwoko bw'ibikoreshwa mu gukumira kwangirika kwa cathodic ndetse ni ubwoko bw'ibikoreshwa mu gukumira ubushyuhe butari stoichiometric. Iyo bikoreshejwe hamwe n'ibindi bikoresho bikoreshwa mu gutunganya amazi, bigaragaza ingaruka nziza zo guhuza. Bifite ubushobozi bwiza bwo kwangiza ubushyuhe kuri iyoni nyinshi z'icyuma nka kalisiyumu, manyeziyumu, umuringa, na zinki. Ndetse bigira ingaruka nziza ku myunyu ngugu y’ibi byuma, nka CaSO4, CaCO3, MgSiO3, nibindi. Kubwibyo, bikoreshwa cyane mu ikoranabuhanga ryo gutunganya amazi. Ibikoresho bya fosforilating bikoreshwa muri serine na pyranose birinzwe.
Gupakira no Kohereza
Gupakira: 25kg nk'uko umukiriya abikeneye.
Kohereza: ni imiti isanzwe kandi ishobora gutangwa hakoreshejwe gari ya moshi, inyanja n'ikirere.
Bika kandi ubibike
Igihe cyo kubika: Amezi 24 uhereye igihe byakorewe mu ipaki y’umwimerere idafunguye, bibitswe ahantu hakonje kandi humutse, kure y’izuba ryinshi, amazi.
Ububiko bufite umwuka uhagije, Butuma ibintu bishya bishyuha, butandukanyijwe n'ibikomoka kuri okiside, aside.
