2, Molecular Formula: (NH4) 2SO4
3, Molecular Luj: 132.14
CAS: 7783-20-2 Nr
5, Cim: Nws yog xim tsis muaj pob tshab orthorhombic siv lead ua, deliquescent.Cov txheeb ze ntom ntom yog 1.769 (50 degree). Nws yooj yim soluble hauv dej (ntawm 0 degree, solubility yog 70.6g / 100mL dej; 100 degree, 103.8g / 100mL dej). Aqueous kua yog acidic. Nws yog insoluble hauv ethanol, acetone los yog ammonia. Nws reacts nrog alkalies los tsim ammonia.
6, Kev Siv: Raws li GB 2760-2011, nws tuaj yeem siv los ua kev pabcuam (tsuas yog siv cov khoom noj rau fermentation). Nws kuj tuaj yeem siv ua khob noom cookie regulator thiab poov xab zaub mov. Hauv kev tsim cov poov xab tshiab, nws tau siv los ua cov khoom siv nitrogen rau kev cog qoob loo (Cov tshuaj tsis tau teev tseg.). Kev noj tshuaj yog kwv yees li 10% (li 0.25% ntawm cov hmoov nplej) rau cov poov xab hauv cov qhob cij.
7, 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.
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.
