Shanghai city Chongming County Fu'an Spring Factory   

My company produces glass packing spring has 30 years of history, mainly to China's pharmaceutical \ fine chemical industry \ Laboratory for the market, in photocatalytic water \ processing \ desulfurization technology has its corresponding application. In North China, South China, East China have business contacts, our purpose: to quality as the basis, to serve as the fundamental, to technology is the premise to expand the market. Can customize various special specifications. Spring glass packing is mainly used in the fine chemical, pharmaceutical and other industries rectification device in the laboratory, pilot, pilot - and full-scale production of packing tower, role fillers: the gas phase and liquid phase through increased contact area, and strongly mixing, can improve the fractional distillation efficiency, sub slide tower used for column chromatography,. Features of corrosion resistance and high filtration efficiency. The diameter and length of the product can be made according to the requirements. The conventional products are 3--8mm in diameter and 6---20mm in length. I our standard glass spring packing & amp; Oslash; 4, the length 10---20mm, packing density 350kg/m3. theoretical plate number 10--20/ meters. Our factory is currently provided by glass material has ordinary glass and GG-17 material two. Compared with the ordinary materials, GG-17 with high temperature resistance, linear thermal expansion coefficient is small, good acid and alkali resistance, corrosive materials to be used for, such as organic acids, some systems do not allow contact with iron, glass packing spring is rectification device in the laboratory, pilot, pilot - and full-scale production of the preferred filler. For the research, education and new product development of organic chemical industry, petrochemical industry, fine chemical industry, bio pharmaceutical chemical industry, etc..
