Khoom noj khoom haus qib Sodium Alginate | 9005-38-3

(1) Colorcom Sodium Alginate yog ib yam khoom los ntawm kev rho tawm ntawm iodine thiab mannitol los ntawm cov xim av algae kelp lossis Sargasso, uas nws cov molecule yog tsim los ntawm β-D-mannuronic acid (β-D-mannuronic, M) thiab α-L-guluronic acid (α-L-guluronic, 1. Cov tshuaj aqueous ntawm sodium alginate muaj viscosity siab thiab tau siv los ua zaub mov thickener, stabilizer, emulsifier, thiab lwm yam.
(2) Colorcom Sodium Alginate yog cov zaub mov tsis muaj tshuaj lom thiab tau suav nrog US Pharmacopoeia thaum ntxov li xyoo 1938. Colorcom Sodium alginate muaj ntau ntawm -COO-, uas tuaj yeem ua rau pom tus cwj pwm polyanionic hauv cov kua dej thiab muaj qee yam nplaum, uas tuaj yeem siv los ua cov khoom siv tshuaj rau kev kho mob ntawm mucosal.
(3) Nyob rau hauv acidic tej yam kev mob, -COO- hloov mus rau hauv -COOH, lub degree ntawm ionization txo, lub hydrophilicity ntawm sodium alginate txo, cov molecular saw shrinks, thiab thaum lub pH tus nqi nce, pawg -COOH tsis tu ncua dissociates, hydrophilicity ntawm sodium alginate nce thiab molecular chain stretches. Yog li, sodium alginate muaj pH rhiab heev.
(4) Colorcom Sodium alginate tuaj yeem tsim cov gel sai sai hauv cov mob me me. Thaum muaj cov cations xws li Ca2+ thiab Sr2+, Na+ ntawm G unit tau txais ib qho kev sib pauv ion nrog divalent cations, thiab cov G units yog stacked los tsim ib tug cross-linked network qauv, yog li tsim hydrogel.
(5) Cov mob me me rau kev tsim sodium alginate gel tuaj yeem zam qhov tsis ua haujlwm ntawm cov tshuaj nquag xws li tshuaj rhiab heev, proteins, hlwb thiab enzymes. Vim yog cov khoom zoo heev, sodium alginate tau siv dav hauv kev lag luam khoom noj thiab tshuaj.
(6) Xim Sodium alginate yog dawb los yog lub teeb daj hmoov, yuav luag tsis muaj ntxhiab thiab tsis qab. Sodium alginate yog soluble hauv dej, tab sis insoluble hauv cov kuab tshuaj organic xws li ethanol, ether, chloroform, thiab lwm yam.
