Technical Characteristics Of EPTFE Film

Dec 24, 2017

The material of the membrane is divided into two major categories, organic and inorganic. The organic polymers include cellulose acetate, polypropylene, polycarbonate, polysulfone, polyamide and so on. The pore size of ceramic and metal films is about 0.1 ~ 10 m, and its operating pressure is about 0.01-0.2MPa. The process operation is divided into two ways: dead end filtering and wrong flow filtering. When dead ends are filtered, the solutes and the solute particles smaller than the membrane pores are blocked by the pressure, and are usually trapped on the membrane surface through the membrane and solute particles larger than the membrane pores. As time increases, more and more particles are accumulated on the surface of the membrane, and the permeability of the membrane will decrease. At this time, it is necessary to stop to clean the surface of the membrane or to replace the membrane. The staggered flow filtration is driven by pressure to flow parallel to the surface of the membrane and takes away the retention of the membrane surface, thus keeping the membrane fouling at a lower level.

Huzhou Sennuo Fluorine Material Technology Limited Company is a hi-tech company focusing on the research and development of the varicosity PTFE microporous membrane and it’s related compounded products.The company lies in the north of Zhejiang province, to the east of Shanghai, to the south of Hangzhou.to the west of Tianmu mountain. The company is to the north of Tai Lake,across which there are Wuxi and Suzhou.Huzhou is the only one city in the name of the lake in the Tai Lake region. There is developed transportation in the city.
