Waxqabadka

HEDPwaa kahortaga jirka ee corrosion acid organophosphoric. Waxay ku kala shaandheyn kartaa ion Fe, Cu, iyo Zn si ay u sameysmaan iskudhisyo iskudhaf ah oo xasilloon.Waxay milmi karaan walxaha oksijiin ee dusha sare ee birahaas.HEDP waxay muujineysaa miisaanka wanaagsan iyo saameynta ka hortagga daxalka ee heerkulka 250 ℃. HEDPwuxuu leeyahay xasilooni kiimikaad wanaagsan oo ka hooseysa qiimaha pH-ka sare, oo adag in la shidayo, oo ay adagtahay in lagu jajabiyo xaaladaha iftiinka iyo kuleylka caadiga ah. Aashitada / alkali iyo u dulqaadashada qiiqa ee koloriinku way kafiican tahay tan asiidhyada kale ee loo yaqaan 'organophosphoric acids' (cusbo).HEDPwaxay ku falcelin kartaa ion bir ah oo ku jira nidaamka biyaha si ay u sameysmaan isku-darka hexa-element, gaar ahaan ion kaalshiyamka. Sidaa darteed,HEDPwuxuu leeyahay natiijo wanaagsan oo ka hortag ah iyo saamayn xadka laga arki karo. Markii lala wadaago kiimikooyinka kale ee lagu daaweeyo biyaha, waxay muujineysaa saameyn is-dhexgal wanaagsan. Xaaladda adag eeHEDPwaa budada kareemada, ku habboon isticmaalka xilliga qaboobaha iyo qaboojinta degmooyinka. Sababtoo ah daahirnimadeeda sare, waxaa loo isticmaali karaa inuu yahay wakiilka nadiifinta ee meelaha elektarooniga ah iyo waxyaabo lagu daro kiimikooyinka maalinlaha ah.

Codsiga

HEDP waxaa loo isticmaalaa sida cabirka iyo ka hortagga daxalka ee wareegaya nidaamka biyaha qabow, dhulka saliida iyo kuleyliyaha cadaadiska hoose ee meelaha sida korontada, warshadaha kiimikada, metallurgy, bacriminta, iwm. HEDPwaxaa loo isticmaalaa in lagu nadiifiyo birta iyo biraha. In warshadaha dye,HEDPwaxaa loo isticmaalaa inuu yahay xasiliyaha peroxide iyo wakiilka dheeha-hagaajiya; Qalabka korontada aan ku jirinHEDPwaxaa loo isticmaalaa inuu yahay wakiilka wax daaya. Qiyaasta 1-10mg / L ayaa loo door bidaa inay tahay xaddidaad celiyaha, 10-50mg / L sida daxalka wax u dhima, iyo 1000-2000mg / L oo ah saabuun Caadi ahaan,HEDP waxaa loo isticmaalaa polycarboxylic acid.
