Product Introduction of Petroleum Grade Welan Gum

Welan gum is a microbial polysaccharide colloid with pseudoplasticity and rheological modification properties. It offers advantages such as high purity, low dosage, high water retention, anti-sagging, thickening, and high adhesiveness, as well as excellent adaptability. It is suitable for the formulation of dry-mixed mortars, dry powder mortars, bonding mortars, as well as spray and pumpable mortars. It can be widely used in prefabricated concrete wall panels, interior walls, plastering, waterproofing projects, and other applications.

Usage of Welan Gum

Welan gum is dissolved in either cold or hot water. While stirring, slowly add the dry powder of Welan gum into the water (natural seawater, artificial seawater, or standard tap water can be selected based on the application formula). Stir thoroughly until fully dissolved, ensuring no lumps remain in the solution. Chempora Welan Gum is a natural biodegradable polysaccharide, and if the solution is stored for more than 4 hours, it is recommended to add a biocide to prevent microbial growth.

Typical applications of welan gum

Application Product	Suggested Dosage (%)	Effect
Drilling Fluid	0.5-1	Excellent resistance to high mineralization and high temperature, making it more suitable for complex well operations such as high-temperature and high-pressure wells
Cementing Slurry	0.05-0.2	Increase the suspension stability of cement slurry in high pH environments and control the water loss of the slurry, thereby stabilizing the wellbore
Spacer Fluid	0.3-0.7	The prepared spacer fluid has good fluidity, low filtration loss, and excellent settling stability
