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. Packaging & delivery packing :paper bag, net 20kgbagdelivery lead time : two weeks after pominimum order : 200kgsupply ability : 1000mt-2000mtyear

Description the product has the general properties of biopolymer such as thickening, suspension, emulsifying, acid-base stability, but also have good high temperature performance, temperature tolerance up to 150 ℃, it can be used deep well drilling fluid, etc in the high temperature environment packaging & delivery packing :paper bag, net 20kgbagdelivery lead time : 2 weeksminimum order : 200kgsupply ability : 1000mt-2000mtyear.

Name: bio surfactant introduction: bio surfactant is a biological macromolecules with a surface activity to be produced by microorganisms with the special conditions (such as a suitable carbon and nitrogen sources, organic nutrients, ph value and temperature, etc ) compared with the chemical synthesis of surfactants, bio surfactant addition to reducing the surface tension, emulsion stability and increase the role of the same foam, but also with the advantages of non-toxic, biodegradable, etc , which chemical synthetic surfactants have no product features: water-soluble, small solid adsorption; better resistance and residual resistance factor, reduce the interfacial tension, better wet ability and reversal for oil rock surface; a plurality of biological macromolecules can bridge to completely block the throat at the same time, so that the water flow around; resistance to salinity 30000mg l, temperature stable at 120 ℃; lower cost, applicability, especially for the presence of the interlayer and the inner heterogeneity of the eor in the oilfields; non-toxic, safety, environmental; product dosages the dosages of product in oilfields is 0.5 to 1%.
