Product description:

We are offering high quality Xanthan gum in large quantity.The product is light beige or milky white powder,also known as xanthan gum, Hansheng gum and yellow monocellular polysaccharide.It is an extracellular microorganism produced by fermentation of sugars by Xanthomonas flavus.It is a structural polymer of pentose repeat unit composed of D-glucose, D-mannose, D-glucuronic acid, acetic acid and pyruvic acid. Its unique molecular structure determines its thickening, shear resistance and stability at high salinity. It can be widely used in drilling fluid, completion fluid, fracturing fluid, oil displacement agent and other fields.

Applications:

Dissolve in cold water or hot water. Slowly pour xanthan gum powder into water while stirring. Stir until it dissolves completely. There is no lump in the solution. Xanthan gum is a natural biodegradable polysaccharide. If the solution is stored for more than 4 hours, it is recommended to add biocides.

1.Typical application of xanthan gum

Drilling fluid:

Added Quantity%: 0.3-1.2

Function:Lubricates drill bits and carries drill cuttings, providing excellent solid transportation and suspension capacity.

Completion fluid :

Added Quantity%: 0.7-1.3

Function:stabilizer, adhesion lubrication, reduce friction resistance of pump, facilitate material transportation

Profile control and water shutoff: 

Added Quantity%: 0.2-0.5

Function: not only reduces the water absorption rate of high permeability zones longitudinally, but also adjusts the main channel of water drive horizontally and adjusts the difference of fluid production between wells.

Oil recovery:

Added Quantity%: 0.1-0.5

Function: Has good injection ability, can greatly improve the sweep degree of water drive, reduce the water cut of oil wells, and thus improve EOR.

2.In industry, it is used as stabilizer, thickener and processing assistant for many purposes, including canned and bottled food, bakery food, dairy products, frozen food, salad condiment, beverage, brewing, candy, pastry color accessories, etc.

Advantages:

1.High viscous properties at low concentration;

2.Resistance to acid, alkali and salt, oxidation resistance and enzymatic hydrolysis;

3.Good dispersion, emulsifying stability, suspended particles and oil droplets.

4.Temperature resistance, shear resistance.
