Application
1, Materials used for drilling mud additives, can reduce the friction of the drill bit to extend the service life of drill bits to improve the penetration rate and the footage, reduce the time for drilling the plug, the collapse of effective anti-wells, in addition to thickening the water used in flooding, fracturing fluid and selective water shutoff, for Enhanced Oil Recovery Significant Effect;
2, In the mining, coal mining industry can be used for waste water, coal washing waste water clarifier.
3, Used for municipal sewage sludge, municipal solid waste and industrial effluent;
4, Paper-making industry for the clarification of liquid caustic soda, fiber dispersing agent, can improve the beating, the filler retention agents, paper strengthening agent, can be used to improve the treatment rate and the white water recovery;
5, Used in Textile, Carpet Industry, Sizing, Quick-setting Cement, Synthetic Resin Coating. Photosensitive Polymers, Adhesives, Dispersing Agent, as well as Agricultural Soil Gel, Slurry Stabilizers, Soil Amendments;
6, Oil field water treatment to deal with the recovery of oil.
Packing Its shelf-life is 2 years and follow non-dangerous transportation; The solid products are packed in kraft paper bag with inner plastic bag, with each bag containing 25 kgs/20kgs or in accordance with customers' demand.
