化学特性 CHEMICAL DESCRIPTION：
EP-AG contains a cationic poly-acryl amide based polymer in an emulsion form. The oil carrier is a low toxicity, high flash point refined petroleum product. EP—AG 是聚丙烯酰胺阳离子化的多聚糖乳化液体。这种输油液是低毒性、高燃点的精细石化产品。
建议用法 RECOMMENDED USES：
EP-AG gives good viscosity development in any strength of hydrochloric acid. And can be used in most acid fracturing operations. It shows excellent compatibility with common inhibitors, nonionic and cationic non-emulsifiers and many other acid additives. This product is an efficient friction reducer at very low loadings. EP—AG在各种浓度的盐酸中都具有很好的增稠性能，可用于大多数酸性压裂作业；它能够很好地与常用抑制剂，非离子和阳离子非乳化剂以及其它的酸处理剂相兼容。此产品是一种低用量而高效能的降磨擦处理剂。
实际应用 TREATINGAPPLICATIONS：
EP-AG is typically loaded at 5-20 gallons per thousand gallons of acid. Good agitation is required for full hydration. Following are some typical viscosity in 15% inhibited acid. 常规用量是5—20kg/1T酸液. 完全溶解需要良好的搅拌。 以下是15%酸抑制液的粘度对照：
添加量Loading	cps   at 511/sec		cps   at 170/sec
10 gal/1000gal      10kg/1t	9.5		12.0
15 gak/1000gal     15kg/1t	15.5		21.0
20 gal/1000gal      20kg/1t	21.0		28.5
Use of 28% acid will give slightly higher viscosities, on suspending; most of the viscosity is also retained to help in suspending fines on flow back. For use as a friction reducer, levels as low as ¼ gal/1K are effective. 使用浓度为28%的酸液时，其浆液粘度将会少微偏高。在粘度接近稳定期间，各种粘度都会维持不变以阻止微细粉粒的回流。当作为润滑剂（降摩剂）使用时，其有效用量可低至0.25kg/1t。
