Mahi

HEDPhe aukati whakakeke waikawa organophosphoric. Ka taea te whakakii ki nga katote Fe, Cu, me te Zn hei hanga i nga puhapuhi chelating pumau. Ka taea te whakakore i nga rauemi waikura ki nga papa o enei konganuku.HEDP whakaatu i te tauine tino pai me te aukati i te aukati i raro i te mahana 250 temperature. HEDPhe pai te pumau o te matū i raro i te uara nui o te pH, he uaua ki te whakamehane, me te uaua ki te pirau i raro i nga tikanga maama me te wera. Ko tana manawanui waikawa / alkali me te rongoa rongoa rongoa he pai ake i etahi atu waikawa waikawa (totiki).HEDPKa taea e ia te whakautu ki nga katote ngota i roto i te punaha wai ki te hanga hexa-element chelating complex, me te katote konupūmā Na reira,HEDPhe pai te panui antiscale me nga paepae kitea. Ka hangaia ana me etahi atu matū rongoa wai, ka kitea he pai nga painga o te synergistic. Tuhinga o muaHEDPhe paura karaihe, he pai hei whakamahi i nga takurua o te takurua me te rohe paari. Na te nui o te ma, ka taea te whakamahi hei horoi horoi i nga waahanga hiko me te taapiri i nga matū o ia ra.

Tono

HEDP ka whakamahia hei pauna me te aukati i te waikura i roto i te haangai o te punaha wai matao, te papa hinu me nga kohua iti-pehanga i nga waahi penei i te hiko hiko, umanga matū, metallurgy, tongi, aha atu. HEDPwhakamahia ana hei horoi horoi mo te whakarewa me te koretake. I roto i te umanga tae tae,HEDPe whakamahia ana hei kaiwhakarite pereki waikawa me te kaihoko whakatika-tae; I roto i te hiko-kore-hiko,HEDPwhakamahia ana hei kaihoko chelating. Ko te inenga o te 1-10mg / L e manakohia ana hei aukati tauine, 10-50mg / L hei aukati i te waikura, me 1000-2000mg / L hei horoi horoi. Te tikanga,HEDP ka whakamahia tahi me te waikawa polycarboxylic.
