1, Tshuaj Lub Npe: Sodium Phosphate di Basic
2, Molecular Formula:, Na2HPO
3, Molecular Luj: 141.96
CAS: 7558-79-4 Nr
5, Cim: Nws yog dawb los yog tsis muaj xim crystalline lossis prismatic siv lead ua. Nws yooj yim soluble hauv dej, tab sis insoluble hauv ethanol. Tus txheeb ze ceev yog 1.52 thiab melting point yog 34.6 degree. Yog rhuab mus rau 180 degree, nws yuav poob dej crystal thiab hloov mus rau anhydrous.
6, Kev Siv: Hauv kev lag luam khoom noj khoom haus, nws yog siv los ua tus neeg sawv cev rau kev ci kom tsis txhob oxidation stain thiab ua emulsifier hauv cov khoom noj siv mis los tiv thaiv qe dawb los ntawm solidification. Nws kuj yog siv los ua emulsifier thiab chelate tus neeg sawv cev rau cov dej qab zib.
7, Ntim: Nws tau ntim nrog lub hnab polyethylene ua txheej txheej sab hauv thiab cov hnab yas sib xyaw ua ke raws li txheej txheej. Qhov hnyav ntawm txhua lub hnab yog 25kg.
8, Cia thiab Thauj Khoom: Nws yuav tsum tau muab cia rau hauv qhov chaw qhuav thiab qhov cua, khaws cia kom deb ntawm tshav kub thiab ya raws thaum thauj, 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.
