Product Description

 

Welan Gum For Cement Mortar Concrete Oil Drilling Petroleum Industry CAS 96949-22-3

 

Description:
Welan Gum is an anionic polysaccharide with excellent thermal stability and retention of viscosity at elevated temperatures. Welan Gum exhibits superior temperature stability over 200° F in fresh water and low pH fluids. Welan Gum is a tan colored dry powder with a density of 26.25 lbs/ft³. Welan Gum is used in various industries where high molecular weight biopolymers are useful.

Application:
WELAN GUM biopolyer is a high efficiency, pseudoplastic viscosifier and suspension agent used in water based drilling, workover and completion fluids. Welan gum is also used in hydraulic fracturing fluids and cementing grouts, foundary coating, pigment suspensions, cement or concrete viscosifier, tire sealant and paint thickeners.

Welan gum is a biological polysaccharide obtained by biochemical fermentation by strains extracted from the culture solution of Alkalibacterium with starch and other carbohydrates as the main raw materials. It is a tetrasaccharide repeating unit composed of D-glucose, D-glucuronic acid, L-rhamnose, and L-mannose. From the molecular formula, because its hydrogen bond exists between the two glycosidic rings on the polymer chain, the viscosity of the solution system increases significantly, making it better adhere to the surface of the substance, so that the entire solution system produces a It has a wide range of bridge effect, thereby increasing the yield value, maintaining good cohesion of the solution system under standing or moderate shear force, making it have excellent thickening and rheological suspension stability.

Warm wheel glue has the following characteristics:

 

Higher viscosity at low concentrations

 

Higher viscosity at low speed

 

Excellent water holding capacity

 

Special stability under high salt conditions

 

high temperature resistance

 

Excellent rheological properties
