Kev Txhais Lus:
Citric acid thiab citric acid monohydrate sib txawv. Citric Acid tuaj yeem tau txais ua daim ntawv anhydrous (tsis muaj dej) lossis ua monohydrate. Daim ntawv anhydrous crystallizes los ntawm dej kub, thaum monohydrate tsim thaum citric acid crystallized los ntawm dej txias. Lub monohydrate tuaj yeem hloov pauv mus rau daim ntawv anhydrous ntawm li 78 ° C.

Siv
Citric Acid Monohydrate yog ib hom tricarboxylic acid uas pom muaj nyob rau hauv cov txiv hmab txiv ntoo citrus. Citric acid yog siv ua ib qho khoom siv hauv kev npaj tshuaj vim nws cov khoom antioxidant. Nws tswj kev ruaj khov ntawm cov khoom xyaw nquag thiab siv ua ib qho preservative. Nws kuj tseem siv ua ib qho acidulant los tswj pH thiab ua haujlwm ua ib qho anticoagulant los ntawm chelating calcium hauv cov ntshav. Tsis tas li ntawd, Citric Acid Monohydrate yog siv ua ib qho acidulating, khoom noj khoom haus additive, thiab synergist hauv cov antioxidant sib xyaw.
Daim Ntawv Thov
Citric acid monohydrate muaj ntau yam kev siv. Nws yog siv rau kev npaj citrate buffer hauv platelets rau intravital microscopy thiab ua ib qho khoom buffer rau unmasking antigens thiab epitopes. Tsis tas li ntawd, nws ua haujlwm ua tus neeg sawv cev pH hauv kev lag luam khoom noj, dej haus, thiab tshuaj. Hauv tsiaj txhu, nws txhim kho kev ua haujlwm ntawm kev siv calcium hauv cov khoom noj.
Cov kev siv tsis ntev los no ntawm citric acid monohydrate suav nrog:
Ua ib qho chaw carbon hauv carbon nanodot synthesis
Txhawm rau npaj cov kua pH-6.0 citric acid monohydrate / buffer rau kev npaj cov qauv ntaub so ntswg
Hauv cov txheej txheem solubilization citric acid los kho ntau yam qauv.
Ntim thiab Xa Khoom
25KG / Hnab los yog raws li cov neeg siv khoom xav tau.
Yog cov khoom siv dav dav thiab tuaj yeem xa los ntawm dej hiav txwv thiab huab cua
Khaws cia thiab khaws cia
Lub neej txee: 24 lub hlis txij li hnub tsim khoom hauv cov ntim khoom tsis tau qhib khaws cia rau hauv qhov chaw txias thiab qhuav kom tsis txhob raug tshav ntuj ncaj qha, dej.
Lub tsev rau khoom muaj cua nkag, ziab kom qhuav kub tsawg, Sib cais ntawm cov tshuaj oxidants, cov kua qaub.
