What is Welan gum？

Wenglun is a soluble extracellular polysaccharide produced by Alcaligenes sp. through aerobic submerged fermentation. Due to its good thickening and anti-segregation properties, it is used as a good stabilizer and thickener. Cement mortar, concrete and other building materials fields.

Specification

Application

1. In the food industry, Brunei gum can be used in the processing of baked products, dairy products, juices, milk drinks, sugar coatings, frostings, jams, meat products and various desserts.
2. In the petroleum industry, Brunei gum can be used to prepare drilling mud to maintain the viscosity of water-based drilling fluid and control its rheological properties. Brunei gum is also a new type of oil-displacing agent, which is used for tertiary oil recovery of oil wells. When Brunei gum is prepared into an aqueous solution of suitable concentration and injected into the well, and pressed into the oil layer to displace oil, the oil recovery rate can be greatly improved. In addition, Brunei gum can also be used as a flow improver in well completion, workover, formation fracturing and heavy oil transportation.
3. Brunei gum can be widely used in cement and concrete. It can enhance the water retention of mud. When it is used as a water retention agent, it does not need to use a dispersant like other additives. Brunei glue can increase the plasticity, suspension capacity, air content, anti-sag ability, flow characteristics and resistance to water loss of cement. These improved characteristics remain unchanged when the temperature increases. Compared with other additives, lower concentrations of Brunei gum can achieve good results.
