Dipotassium Phosphate
Dipotassium Phosphate
Kev siv:Hauv kev lag luam khoom noj khoom haus, nws yog siv los ua tus neeg sawv cev buffering, tus neeg sawv cev chelating, cov khoom noj poov xab, emulsifying ntsev, synergistic tus neeg sawv cev ntawm anti-oxidation.
Ntim:Nws tau ntim nrog lub hnab polyethylene ua txheej txheej sab hauv, thiab lub hnab yas sib xyaw ua ke raws li txheej txheej.Qhov hnyav ntawm txhua lub hnab yog 25kg.
Cia thiab thauj:Nws yuav tsum tau muab khaws cia rau hauv qhov chaw qhuav thiab qhov cua, khaws cia kom deb ntawm tshav kub thiab noo noo thaum lub sijhawm thauj mus los, tshem tawm nrog kev saib xyuas kom tsis txhob muaj kev puas tsuaj.Tsis tas li ntawd, nws yuav tsum tau muab cais tawm ntawm cov tshuaj lom.
