Sell Welan gum

Description

• Characteristics of Welan Gum
  1. can be dissolved in cold water, it presents regular and stable structure in aqueous solution,and forms the high viscosity solution.
  2. has the characteristics of pseudoplastic flow (shear thinning effect),and a good ability of suspension in the stationary state.
  3. It is relatively stable in the range of PH***2 and has good salt tolerance.
  4. welan gum can form a gel under the conditions of NaOH existence and heating, but the gel strength is very weak.
  5. It has the thermal reversibility for the stability of temperature, the influence of temperature on the Welan gum is relatively small. Under the condition of **1 ? terilization for *5 minutes, its viscosity will not decrease. The viscosity of 0.4 xanthan gum solution has been zero when the temperature is **5? , but the vidcosity of welan gum solution was just close to zero under the same conditions when the temperature is up to **3?. Under the normal conditions, the viscosity of welan gum solution will decrease with the the temperature increasing and with the temperature lowering, it can completely restore.
  6. It has better compatibility with other gum.
   
• Usage of Welan Gum
  Because of the shear thinning effect and excellent rheological properties of Welan gum, it mainly is used in all aspects of industry and agriculture as a thickening agent, suspending agent, emulsifier, stabilizer, lubricants, and adhesives . It also has a wide application prospect in food, concrete, oil, ink and other industries.
  
  1. In the food industry, Welan gum can be used in bakery products, dairy products, fruit juice, milk beverages, sugar, icing sugar, jam, meat and all kinds of desserts processing.
  2. In the oil industry, Welan gum can be used for deployment of drilling mud in order to maintain the viscosity of water-based drilling fluid and control its rheological properties. Welan gum is also a new type of oil displacement agent used for tertiary oil recovery wells.Deploying aqueous solutions of welan gum with the right concentration injection into the wells, and putting the pressure into the oil reservoir, it can greatly improve the oil recovery rate. In addition, Welan gum can also be used in flow improver of completion, workover, stratum fracture, and heavy oil transportation.
  3. Welan gum can also be widely used in cement and concrete, and enhance the water retention of mud, and it does not need to use dispersants like other additives when used as the water retention agent. Welan gum can increase the plasticity, suspension amount, air content, and ability of anti-subsidence and flow characteristics and anti-dehydration of cement. These characteristics of improvements remain unchanged when the temperature increases. Compared with other additives, Welan gum with the lower concentration can achieve a very good effect.
