also known as Welan Gum and Welan Gum, is a kind of product made from Alcaligenes sp., using starch as the main raw material, fermented by specific organisms, purified, dried and pulverized by ethanol. Highly viscous water-soluble microorganisms metabolize polysaccharides. The structural skeleton of welan gum is composed of D-glucose, D-glucuronic acid, D-glucose and L-rhamnose units.

Application of Welan Gum
Due to the shear thinning effect of Brunei gum and its excellent rheological properties, it is mainly used as a thickener, suspending agent, emulsifier, stabilizer, lubricant, film-forming agent and adhesive in various industrial and agricultural applications. aspect. It has wide application prospects especially in industries such as food, concrete, petroleum, and ink.
1. In the food industry, warm rubber can be used in the processing of bakery products, dairy products, juices, milk drinks, sugar coatings, frostings, jams, meat products and various desserts.
2. In the petroleum industry, warm wheel rubber can be used to prepare drilling mud to maintain the viscosity of water-based drilling fluid and control its rheological properties. Warm rubber is also a new type of oil displacing agent, which is used for tertiary oil recovery of oil wells. The oil recovery rate can be greatly improved by preparing an aqueous solution of suitable concentration and injecting it into the well and pressing it into the oil layer to displace oil. In addition, warm rubber can also be used as a flow improver in well completion, well workover, formation fracturing and heavy oil transportation.
3. Welan 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, there is no need to use a dispersant like other additives. Warm wheel rubber 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 warm wheel rubber can achieve good results.
Compared with traditional thickeners (such as cellulose ether), Wenlun glue, Wenlun glue, and Dingyou glue can effectively improve the use status of concrete and dry-mixed mortar at lower dosages, and enhance the water retention of cement systems. Thickening properties give the cement system excellent rheological properties, thereby solving application problems such as bleeding and segregation.
