表面活性剂

We use separated pre-treatment, coagulating sedimentation, air flotation and sand filtration to treat coating wastewater and obtains good results: the removal rate of CODCr could be higher than 80%.

摘 要：本文针对汽车涂装废水中含有树脂、表面活性剂、重金属离子，Oil、颜料等污染物，特别是其中的电泳废水、喷漆废水成份复杂，浓度高，可生化性差的实际情况，采用分质处理、混凝沉淀、混凝气浮、砂滤等工艺对涂装废水进行处理，取得了良好效果：CODCr去除率大于80%。

In this article, in allusion to the contamination of coating wastewater of automobile manufacturing which contains resin, surface active agent, heavy metal ion, oil, paint, dyestuff etc, especially the ELPO wastewater and painting wastewater which is complex, and has high concentration. we use separated pre-treatment, coagulating sedimentation, air flotation and sand filtration to treat coating wastewater and obtains good results: the removal rate of CODCr could be higher than 80%.

The adsorption amount of OCS surfactant on Block 1219 reservoir sand was lower than 2mg/g at an injection concentration of 0.5%.

在注入浓度0.5%时，OCS表面活性剂在大港油田枣1219断块岩心上的吸附量小于2mg/g油砂。

The aggregations assembled by the surfactant, which acted as soft templates, played an important role in the reaction.

其中表面活性剂的组装体作为反应的软模板起了非常重要的作用。

He has 20 yeas– research experience in surfactant application and agrochemical formulations.

他有20年的表面活性剂应用和农用化学品制剂的研究经验。

As a key enterprise in detergent industry in China, it took us more than 30 years to grow up as a large-scale joint-stock company focusing on producing and selling synthetic detergent and industrial surfactant.

作为专业生产合成洗涤剂的企业，历经三十多年的磨砺，已发展成为一个以生产经营合成洗涤剂及工业用表面活性剂为主业的大型股份制企业。

With the development of science and production,people manufacture better "soap"-synthetic detergent,its species are increasing,and the scope of application is beyond the field of "washing".Such substances should not have been easy to "soap" and "detergent",but to "surfactant".

随着科学和生产的发展，制造出更好的&肥皂&——合成洗涤剂，其品种和产量不断增加，应用范围远远超出了&洗涤&领域，这类物质已不能简单地以&肥皂&和&洗涤剂&来称呼，而以&表面活性剂&这一名词来统称。

Most of the sizing agents are surfactants, among them, in the case of the hydrophobic ones, longer the carbon chain, more difficult to biodegrade, and the straight chain structure has better biodegradability than the branch one.

浆料助剂多数为表面活性剂，疏水的碳链越长越难生物降解，直链结构较支链结构的生化降解性相对较好。

Furthermore, we investigate the dependence of surface morphologies and continuities of metallic structures on fabrication conditions.

我们通过将表面活性剂引入多光子光还原过程，限制了金属纳米颗粒的还原生长，使多光子加工技术的金属加工分辨率超过传统光学理论衍射极限，实现了纳米尺度的金属加工。

Quaternary ammonium compound category, ethylene oxide, composite aldehydes, chelating agent, surfactant, the activity factor.

复合季铵盐类、环氧乙烷、复合醛类、螯合剂、表面活性剂、活性因子。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
