Gelatin and sodium alginate alone inSodium alginate food applications at home and abroad have carried out a more in-depth study of the two together in the food much, studies have shown that the concentration of gelatin and sodium alginate sol system will affect theviscosity, with the rise of the gelatin concentration, viscosity increases; and with the increase in the concentration of sodium alginate, the viscosity increased rapidly.
PH value, ionic strength on the viscosity of gelatin and sodium alginate significant, indicating that the main force of the interaction between gelatin and sodium alginate electrostatic attraction. On the basis of the above, PH reasonable conditions for production of around 6.0 bionic shark fin, and curing conditions bionic shark fin, the ratio of the concentration of gelatin and sodium alginate bionic shark fin to do the actual explore research, comprehensive coarse protein content, hardness, tensile strength, transparency, and the loss rate factors, biomimetic shark fin dope PH 6.0, system gelatin concentration m (gelatin), 8% -10%, the alginate concentration is m (sodium alginate ) 1.5% -2%, the better the quality of the obtained bionic shark fin.
Thank you so much for the post you do. I like your post and all you share with us is up to date and quite informative, i would like to bookmark the page so i can come here again to read you, as you have done a wonderful job. dental impression material
