Pyrophosphoric acid CAS 2466-09-3
Pyrophosphoric acid yog cov xim tsis muaj koob zoo li siv lead ua los yog cov kua uas tsis muaj xim tsis muaj kuab paug uas tsim cov muaju tom qab lub sijhawm ntev cia thiab tsis muaj xim iav. Pyrophosphate ions muaj kev sib koom ua ke muaj zog, thiab ntau dhau P2O74- tuaj yeem yaj cov ntsev pyrophosphate insoluble (Cu2+, Ag+, Zn2+, Mg2+, Ca2+, Sn2+, thiab lwm yam) los tsim kev sib koom tes ions, xws li [Cu (P2O7) 2] 6-, Sn (P2O7) 2] 6-, thiab lwm yam. Nws yog feem ntau siv los ua cov catalyst hauv kev lag luam los tsim cov organic phosphate esters, thiab lwm yam.

Pyrophoric acid yog siv los ua catalyst, masking agent, hlau refining agent, thiab stabilizer rau organic peroxides. Nws kuj yog siv los kho tus nqi Ph ntawm cov tshuaj electroplating hauv cov txheej txheem tooj liab electroplating. Pyrophoric acid dej tuav tus neeg saib xyuas, kev txhim kho zoo, pH regulator, hlau chelating tus neeg saib xyuas.
Feem ntau ntim rau hauv 25kg / nruas, thiab kuj tuaj yeem ua pob customized.
