Welan gum

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 effec.

Anti-high temperature biopolymers

Anti-high temperature biopolymers.These resins require some care in molding so as not to exceed their heat, shear, and hydrolytic stability. Materials suppliers have been developing new and enhanced grades with improved processability and end-use properties, which could help the material to advance into a wider range of applications. Additive suppliers have also come out with products to overcome processing and performance limitations.

“We have worked with the majority of the leading suppliers of biopolymers and have trialed the materials extensively,” says Michael McGee, director of technology at Nypro in Clinton, Mass. It’s not as simple as a drop-in substitution for a familiar material like PP. “The rheology, shrink rates, and venting requirements are different from material to material, but the differences are subtle so you have to understand product design, tool design, processing equipment and the parameters of your process. We have been amassing considerable knowledge about biodegradable and biobased materials. We understand more now about their drying, about gate design and location, runner channels, flow rates, venting, and molding.”

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.

bio surfactant

Rhamnolipids are bio surfactant naturally occurring glycolipids produced commercially by the Pseudomonas aeruginosa species of bacteria. P. aeruginosa produces both mono-rhamnolipids and di-rhamnolipids. Many strains of P. aeruginosa can produce rhamnolipids both aerobically and in some cases by anaerobic fermentation. Rhamnolipids function as a natural surfactant, emulsifier, fungicide, and antibiotic.

In pure form, rhamnolipids are a white powder when desiccated. Generally rhamnolipids are supplied and used in an aqueous solution. The solution may range from clear to milky white or tan in color, depending on concentration and purification. When used as a surfactant, only low concentrations are necessary.

As a natural “green”, non-carcinogenic product, rhamnolipids are just now beginning to be used to replace petroleum-based chemicals in cosmetics, soaps, shampoos, detergents, pharmaceuticals, agricultural sprays, etc. as those currently used petrochemicals are being phased out or banned.

Rhamnolipid biosurfactant

Rhamnolipid bio surfactant is a liquid contact biofungicide used in agricultural, horticultural and turf
Settings to prevent and control plant pathogens such as downy mildews, Pythium and Phytophthora.
Studies have shown that rhamnolipid biosurfactant is not generally toxic, but is corrosive to eyes.
When applied according to label directions by appropriately protected handlers, no adverse effects on
Humans or the environment are expected from the use of this biofungicide.

Description:
Rhamnolipid biosurfactant is a mixture of two structurally related rhamnolipid molecules.
The active ingredient is prepared commercially by controlled aerobic fermentation of a
Strain of the soil-borne bacterium Pseudomonas aeruginosa. Strict quality controls assure that no bacteria are present in the manufactured product. The rhamnolipid molecules are simple glycolipids comprised of a fatty acid tail with either one or two rhamnose rings at the carboxyl end of the fatty acid. Rhamnose is a sugar which the Food and Drug Administration has approved as a food additive. Fatty acids, a major source of energy in the body, are ubiquitous in animals and plants. Exposure to rhamnolipids and other biosurfactants is widespread. Rhamnolipid biosurfactant works by disrupting cell membranes; The targeted fungal pest zoospores are especially vulnerable because they lack the protective cell wall present in the fungal pest's other life stages.
