Barbed Rubber Indus 

 Indus Barbed gum is the natural macromolecular Luedaisuanwei polysaccharide, molecular weight up to 9,000,000 Daltons. Powder dissolved in water is not a true solution, but significant swelling into gel (can be increased to 60-100 times the original volume. Water solubility maximum in the pH6-8; solubility viscosity changes with the pH value change. Generally speaking, to be fully hydrated gum solution and then adjusting the pH value than the acidification of the viscosity of access to much smaller. thorn Indus gel solution under acidic conditions in the pale color. while under alkaline conditions the color deepened. concentration below 0.5%, continued to show the relationship between concentration and viscosity is proportional to: the concentration of more than 0.5% solution has shown a non-Newtonian fluid properties. the existence of both temperature and electrolyte solution viscosity are affected, the concentration in the 2-3 % or more, become a paste, a soft gel when a higher structure. Application: used as adhesive and suspending agent, stabilizer, into the glue, gelling agent.
