| Description: | Welan gum is a biopolysaccharide via Alcaligenes fermentation using starch or other carbohydrates by the method of biological engineering. It is a tetrasaccharide repeating unit consisting of D-glucose, D-glucuronic acid, L-rhamnose, and L-mannose. From the molecular formula, because of its hydrogen in the polymer chain between the two glycosidic rings, resulting in significant increase in viscosity of the solution system to enable it to better adhesion to the surface of the material, the solution system to produce a large Range of the bridge effect, thereby increasing the yield value, in the standing or moderate shear force to keep the solution system better cohesion, it has excellent thickening, rheology and suspension stability. Welan gum is widely used in drilling fluid and completion fluid, self-compacting concrete admixture, textile printing and dyeing, firefighting agent, ink printing, casting coating, detergent, coating agent, pottery and porcelain in oilfield chemistry with its excellent physical and chemical properties. Microcapsules and non-fluorine-based protein and many other industries | |
