The method is characterized in that: mixture of macromolecular dihydric alcohol and a dihydroxybutyl-terminated polydimethylsiloxane is dehydrated, added with diisocyanate for reaction, then added with a bis propionic acid, a dihydric alcohol chain extender and a catalyst - dibutyl tin laurate, and is diluted by acrylic ester; temperature reduction and emulsion are performed on the mixture after reaction; chain extension reaction is performed in water by a multi-amine chain extender, and siloxane modified polyurethane dispersoid which contains acrylic ester monomer is prepared; and an initiator - potassium persulphate is added into the siloxane modified polyurethane dispersoid for emulsion polymerization.

特征是先将大分子二元醇与二端羟丁基聚二甲基硅氧烷的混合液脱水后加入二异氰酸酯，反应后加入二羟甲基丙酸、二元醇扩链剂和催化剂二月桂酸二丁基锡，并用丙烯酸酯进行稀释，反应后降温乳化，用多元胺扩链剂在水中进行扩链反应，得到含有丙烯酸酯单体的硅氧烷改性聚氨酯分散体，然后再通过加入引发剂过硫酸钾进行乳液聚合。

Washing and distilling are two common ways of removing water, and the later is better.

洗涤和蒸馏是有机液体脱水的两个常用工艺，后者的效果比前者更佳。

My big campaign is to get people off of dry food.

The liquid level of separator at gathering station uses dual－figure control and continuouly detecting the liquid level of the separator by differential liquid level transducer.

气体在集气站内的初脱水及排水计量是由高效分离器完成的，因此有效地控制分离器内的液面是个关键问题。

The dried materials after the de-watering will go up with the heat-air flow. The step rings will stop and keep the big particles. Small particles will be discharged out of the drier from the ring center and will be restored by the whirl separator and dust remover. The not-fully-dried or big piece materials will be sent to the wall of the equipment by centrifugal force function and be smashed again after they fall down to the bottom.

脱水后的干物料随热气流上升，分级环将大颗粒截留，小颗粒从环中心排出干燥器外，由旋风分离器和除尘器回收，未干透或大块物料受离心力作用甩向器壁，重新落到底部被粉碎干燥。

The plan is deigned in raise control levels and automatic .It is studied that is equipment parameter of, temperature, pressure, oxygen content and dustiness, monitor and control technology is realized, Secure and reliance.

同时对污泥的脱水率、出料速度和干化温度、干化时间的最佳匹配控制技术；设备的抗腐蚀、磨损技术进行了研究。

We can predict that more application of electroosmosis in dewatering will be more useful in the f.
