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

Pyrophoric acid siv ua catalyst, masking agent, metal refining agent, thiab stabilizer rau organic peroxides. Nws kuj siv los kho qhov PH ntawm electroplating kua hauv cov txheej txheem electroplating tooj liab. Pyrophoric acid dej khaws cia tus neeg sawv cev, zoo improver, pH regulator, hlau chelating tus neeg sawv cev.
Feem ntau ntim rau hauv 25kg / nruas, thiab kuj tuaj yeem ua pob khoom raws li koj xav tau.
