Waxqabadka

HEDP waa organophosphoric acid inhibitor daxalka. Waxay ku chelate karaa Fe, Cu, iyo Zn ions si ay u sameeyaan xeryahooda chelating deggan.Waxay milmi kartaa walxaha oksaydhsaydhsan ee dusha birahan.HEDPwaxay muujinaysaa miisaan aad u fiican iyo saamaynta xakamaynta daxalka ee heerkulka 250 ℃.HEDP Waxay leedahay xasillooni kiimiko oo wanaagsan oo hoos timaada qiimaha pH ee sarreeya, way adag tahay in la nadiifiyo, wayna adag tahay in lagu burburiyo iftiinka caadiga ah iyo xaaladaha kulaylka. Asiidhkeeda/alkaliyada iyo dulqaadka oksaydhka koloriinta ayaa ka fiican kan acids organophosphoric kale (milix).HEDP waxay kaga falcelin kartaa ion birta ah ee nidaamka biyaha si ay u sameeyaan kakan chelating hexa-element, gaar ahaan ion calcium. Sidaa darteed,HEDP waxay leedahay saameyn liddi ku ah oo wanaagsan iyo saameyn la arki karo. Marka lagu daro kiimikooyinka kale ee daaweynta biyaha, waxay muujinaysaa saameyn wanaagsan oo is-dhexgal ah. Xaaladda adag eeHEDP waa budada crystal, ku haboon isticmaalka xilliga qaboobaha iyo degmooyinka qaboojinta. Sababtoo ah nadiifinteeda sare, waxaa loo isticmaali karaa sidii wakiilka nadiifinta ee beeraha elektiroonigga ah iyo sida lagu daro kiimikooyinka maalinlaha ah.

Codsiga

HEDPwaxaa loo isticmaalaa sida miisaanka iyo xannibaadda daxalka ee wareegga nidaamka biyaha qabow, beerta saliidda iyo kuleyliyaha-hooseeya ee beeraha sida korontada, warshadaha kiimikada, metallurgy, bacriminta, iwmHEDP waxaa loo isticmaalaa saabuun ahaan biraha iyo kuwa aan birta ahayn. Warshadaha midabaynta,HEDP waxaa loo isticmaalaa sida stabilizer peroxide iyo wakiilka dheeha-hagaajinta; Qalabka elektaroonigga ah ee aan cyanide ahayn,HEDP waxaa loo isticmaalaa sida wakiilka qayilaada. Qiyaasta 1-10mg/L ayaa la door bidaa sida xakameeyaha miisaanka, 10-50mg/L sida daxaleeyaha, iyo 1000-2000mg/L sida saabuunta. Caadiyan,HEDPwaxaa lagu daray polycarboxylic acid.
