    The largest company for Calcium Chloride in China

    Our Calcium Chloride is made from the Soda effluents of soda ash production. The effluents used to be discharged into the Sea and caused serious pollution. After the processing from Soda effluents to Calcium Chloride, the pollution has been effectively eliminated. Calcium Chloride 74 % Flakes, 77 % Flakes and Calcium Chloride 94 % Pellets are our major products, which are widely used in oil drilling, food producing, road de-icing etc.

    With the annual capacity of 300,000Mt, we are the largest company for Calcium Chloride in China and have been supplying to our customers worldwide since 2000.

    The Leading company for Xanthan Gum in China

    Xanthan gum is a high molecular weight polysaccharide produced by viscous fermentation. Its unique functionality compared to other commercial polysaccharides is provided by the actual structure of the Xanthan gum molecule. It is widely used as a thickener and stabilizer in oil drilling industry and as food additives in food industry.

    With annual capacity of 100,000Mt, our Xanthan Gum products are enjoying good reputation for its competitive price and high quality.

    The leading company for Sodium Formate and Potassium Formate in China

    In the oil and gas industry, formate brines are the main ingredients of drilling and completion fluids used for reservoir sections in high-pressure high-temperature (HPHT) drilling.

    Our capacity for Bromides is 150,000Mt. We are supplying both the solid form and brine to our customers worldwide.

    Application:

    Oil drilling and exploitation grade xanthan gum is specially produced as mud additive for oil drilling and exploitations. Being an environmentally friendly and high efficiency mud additive, oil drilling and exploitation grade xanthan gum has an excellent tolerance to the changes of temperature, acid, alkaline and salt. Meanwhile, it can extremely increase the products penetrating ability and suspending performance to small solid materials, and reduce the pressure loss during drilling.
    This xanthan gum can not only fasten the well bore, but decrease the damage to oil formation. It can also greatly raise the efficiency of drilling, workover and completion. As a biotype oil driver, oil drilling and exploitation grade xanthan gum can improve oil extraction rate and utilization factor of natural resources. The more important point is that it can furthest protect natural environment.

    Method of Addition:

    To obtain homogeneous solution, efficient dispersion is necessary. The most convenient method of dispersing these products is with a polymer eductor or a commercially available dry powder feeder unit. Solution should be made up at 0.1 - 0.3% solid. Make-up water temperature should be between 10 and 48℃ for optimum product performance. Following dispersion into agitated water, stirring should continue for about an hour to ensure complete dissolution. Stirring maybe carried out by propeller type stirrer with a speed of 200 - 500rpm. It is recommended to have both a stock make-up tank and a solution holding tank for dosage into the system. The above recommended anionic solution concentration are stable for up

    to one week. Aluminum, zinc, copper, or iron should be avoided in make-up system.

    Packing:

    25kgs craft paper bags.
