Xanthan gum, is a natural polysaccharide and important biological polymer Product Description

Xanthan gum, is a natural polysaccharide and important biological polymer, made from carbohydrates as the main raw materials by cabbage black rot xanthomonas bacteria through biological fermentation. Advantages 1. Used as thickener, emulsifier, suspending agent, stabilizer 2. Can increase the viscosity of drilling fluid and shear force, widely used in non-solid-phase drilling fluid, completion fluids and workover fluid, to effectively prevent formation damage. 3. High viscosity, characteristics of well lsalt-resistant 4. pH stability, well heat stability, temperature range (-18-130 º C) 5. Unique rheology, the viscosity of the solution decreased rapidly through the shear action, once the shearing was stoped, the viscosity of the solution will immediately come back. 6. Strong antioxidant and anti-enzyme effect USAGE AND DOSAGE: Added at constant speed with filler, agglomeration and spill should be avoided. The dosage is 0.2%-1.2%, adjusted if necessary.
