评价了3种起泡剂在不同酸液基液中的起泡性能,并测试了稳泡剂、温度、矿化度对起泡剂的起泡性能和泡沫稳定性的影响,优选出合适的起泡剂与稳泡剂,并确定了泡沫酸配方。通过泡沫酸体系与碳酸岩岩屑的反应得到如下结论:泡沫酸比常规酸具有更好的缓蚀作用,能够起到深部解堵作用,提高地层孔隙的渗透性。对单一含水岩心的封堵试验结果表明:在注入泡沫酸后,入口压力上升,说明泡沫进入岩心孔隙后,起到了暂堵作用,体现了泡沫酸具有较好的暂堵效果,对非均质地层较为适用。 相似文献

Cation-Active Laundry Refining Agents Laundry refining agents, which were introduced in U.S.A. about 15 years back, are currently available in Germany and other countries as well. They are almost exclusively prepared from biodegradable quaternary distearyl-ammonium salts because, although insoluble in water, they form stable aqueous dispersions. The complicated processes which occur after the fibres come in contact with the laundry refining agents are very interesting. Amongst other aspects, the authors deal with the problems of substantivity and adsorption and those of wetting. Furthermore, experiences gathered in the rinsing with laundry refining agents, which are of value to laundry experts, are narrated. Finally, the authors have tried to answer the question, whether the present day laundry refining agents are adequate for the consumer demands. 相似文献

Nowadays laundry detergents are becoming increasingly popular as they can be metered automatically into the washing machine, impart softness, antistaticness, resiliency to fabrics, mild to eyes and skins and shows good dispersibility in water. Because it is consumed when it is used, the sale of laundry detergent is a rather large business. There are many different kinds or brands of laundry detergent sold, many of them claiming some special qualities as selling points. A Laundry detergent composition is a formulated mixture of raw materials that can be classified into different types based on their properties and function in the final product. The different classes of raw materials are surfactants, builders, bleaching agents, enzymes, and minors which remove dirt, stain, and soil from surfaces or textiles gave them pleasant feel and odour. The physico-chemical properties of surfactants make them suitable for laundry purposes. Laundry detergent has traditionally been a powdered or granular solid, but the use of liquid laundry detergents has gradually increased over the years, and these days use of liquid detergent equals or even exceeds use of solid detergent. This review paper describes the history, composition, types, mechanism, consumption, environmental effects and consumption of laundry detergents. 相似文献
