Problems solved by technology

When the warm rubber is used in the field or at sea, the powder is easy to fly, and the loss is large, and it falls on the work surface and forms a solution after meeting water, which makes the work table slippery. The safety of the operator is poor; and the powder temperature rubber is used directly. When added to oil-based mud in oil drilling, the solution is incomplete and easy to agglomerate, which affects the use efficiency; in addition, there are problems such as cumbersome use process and difficult operation of powdered temperature wheel rubber

Abstract

The invention belongs to the field of preparation of microbiological polysaccharide solution, and especially relates to a preparation method of a paste welan gum. The preparation method comprises the following steps: inoculating sphingomonas paucimobilis (CGMCC No.1561) to a sterile fermentation culture medium, which contains a carbon source, a nitrogen source, inorganic salts, and water; then carrying out extraction and solid-liquid separation, and finally manufacturing the paste welan gum. In the prior art, the welan gum powder cannot be directly applied to oil-based slurry in petroleum drilling wells and the operation safety of welan gum powder is bad. The provided paste welan gum solves the problems mentioned above. The preparation method is simple. The paste welan gum is suitable for industrial production, transportation and preservation. The stability of the paste welan gum is good. The paste welan gum can be rapidly and evenly mixed with oil-based slurry. Moreover, no dust is generated during the using process, the environment is protected, and the material consumption is reduced.

Description

technical field [0001] The invention belongs to the preparation of microbial polysaccharides, in particular to a preparation method of ointment and body-warming rubber. Background technique [0002] WELAN GUM is an industrial-grade microbial polysaccharide, which contains neutral sugar, D-glucose, D=glucuronic acid, L-rhamnose and L=mannose, and glycoside-bonded acetyl esters base. Jansson PE, LindbergB and Widmalm G (1985) described the structure of the polysaccharide in "Carbohydrate Research" (139, 217-223), and the patent No. 200610012511.0 discloses a preparation method of Wenlun glue, The current Wenlun glue is solid powder and has good temperature resistance. Its 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 cement industry to increase ore sand. Consistency and rheological properties, improve the stability of concrete self-compacting, increase the com...
