Glass Spring, also known as spring-type glass, is made into a spring ring by using a mould. By the capillarity of the glass filament, the liquid film is dispersed, the contact area between air and liquid is increased, and strong mixing is obtained. The separation efficiency of glass spring packing is lower than that of ring packing and triangular spiral packing, but the separation efficiency of glass spring packing is higher than that of Ceramic Rasch ring. Glass Spring Filler is mainly used for corrosive materials, such as JI acid, some materials and iron ion contact is not allowed, glass spring Filler is the laboratory priority filler. ADVANTAGES: Corrosion resistance, high filtering efficiency, low manufacturing cost. DISADVANTAGES: The separation efficiency is lower than the same diameter mesh ring packing and triangular spiral packing, but higher than the porcelain Lacian ring. Filling material product specification (diameter height, mm) : 4 ~ 10 glass filament diameter: 0.5 mm, packing density: 0.45 ~ 0.50kg/l
