Kagwiritsidwe Ntchito
DL - Tartaric Acid ndi mankhwala ogwiritsidwa ntchito mosiyanasiyana omwe amagwiritsidwa ntchito mosiyanasiyana. Amagwiritsidwa ntchito kwambiri m'makampani opanga zakudya ndi zakumwa ngati chowonjezera asidi, chowonjezera kukoma, komanso chowongolera pH. Imatha kupereka kukoma kowawa ndikuwonjezera kukoma kwa zinthu monga zakumwa zoziziritsa kukhosi, madzi a zipatso, ndi maswiti. Mumakampani opanga mankhwala, imagwiritsidwa ntchito popanga mankhwala komanso ngati chothetsera chiral. Kuphatikiza apo, DL - Tartaric Acid imagwiritsidwanso ntchito m'makampani opanga mankhwala popanga ma esters ndi zinthu zina zachilengedwe. Imagwiritsidwanso ntchito m'zinthu zina zodzikongoletsera komanso zosamalira munthu payekha kuti isinthe pH ndikuwonjezera kukhazikika kwa mapangidwe.
Kulongedza ndi Kutumiza
25KG/Drum kapena malinga ndi zomwe makasitomala amafuna.
Ndi katundu wamba ndipo amatha kutumizidwa kudzera m'nyanja ndi mlengalenga
Sungani ndi kusunga
Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Nyumba yosungiramo zinthu zopumira mpweya, Youma pang'ono, Yosiyana ndi ma oxidants, ma acid.
