Chemical Properties:

WELAN GUM is a new type of microbial polysaccharide after xanthan gum, gellan gum, and warm wheel gum. It is a water-soluble biopolymer produced by microbial fermentation.WELAN GUM has excellent Chemicalbook thickening, pseudoplasticity, high temperature resistance, It has excellent characteristics such as high salt resistance and wide range of pH adaptability. It can be widely used in petroleum, building materials and other industries with broad application prospects.

Application:
  1. WELAN GUM is a soluble extracellular polysaccharide produced by Alcaligenessp (Alcaligenessp) through aerobic deep fermentation. Because of its good thickening and anti-segregation properties, it is used as a good stabilizer and thickener. Building materials such as cement mortar and concrete. Application The temperature wheel rubber is a solid powder and has good temperature resistance.
  2. WELAN GUM aqueous solution has good viscosity and rheological properties, and can withstand high concentrations of calcium ions. It can be used as a cement admixture in the Chemicalbook cement industry to increase the content of ore Consistency and rheological properties improve the stability of concrete self-compacting and increase the compressive bleeding of slurry concrete. It can be used in the petroleum drilling industry to provide thickening, suspension and rheological properties for petroleum mud. It can also be used in fine chemical, daily chemical and other industries. Uses: Used in high molecular polymers, oilfield applications, foundry coatings, pigment suspensions, cement or concrete thickeners, tire sealants and coating thickeners.
  3. WELAN GUM a method for extracting Dingyou gum from the fermentation broth of Dingyou gum is to extract Dingyou gum from the fermentation broth after centrifugation and extraction; it includes the following process steps: A, fermentation broth pretreatment A1, fermentation containing Dingyou gum Add lysozyme with an enzyme activity of 100,000 u/g to the solution at pH=6-8. The concentration of lysozyme in the fermentation broth is 100-200ppm. After stirring, the reaction is maintained for 3-5 hours; A2, step A1 After the reaction, the fermentation broth is heated to 130°C-140°C for 5-8 minutes and then reduced to 60-70°C. Acid protease with an enzyme activity of 50000u/g is added. The concentration of acid protease in the fermentation broth is 200-400ppm. =3-4, at a temperature of 50℃-60℃, react for 2-4 hours to prepare the fermentation broth after pretreatment; B. One-time extraction: according to the fermentation broth after pretreatment: the volume percentage is not less than 85% Ethanol solution=1:0.5-0.6, mix the two Chemicalbooks and stir for 30-40 minutes, adjust the pH of the mixed solution to 8.0-9.5, and make Dingyou glue flocculent precipitation; C. Centrifugation once: Step B Solid-liquid separation of the mixed liquid in the mixture to obtain fibrous Dingyou glue; D. Secondary extraction: the fibrous Dingyou glue made in step C: ethanol solution with a volume percentage of not less than 85% = 1: 0.3-0.5 After mixing the two in the ratio of the two, stir for 30-35 minutes, adjust the pH of the mixed solution to 6.0-6.5, so that the Dingyou glue is flocculent; E. Second centrifugation: solidify the mixed liquid made in step D Liquid separation to obtain fibrous Dingyou glue; F, three elution: according to the fibrous Dingyou glue made in step E: ethanol solution with a volume percentage of not less than 85% = 1:0.4-0.6 After mixing, stir for 30-35 minutes, adjust the pH of the mixed solution to 6.0-6.5, make the Dingyou glue flocculent precipitate, and separate the mixed liquid into solid and liquid to obtain the fibrous Dingyou glue.
