The working principle of the device is to separate the solid and the liquid. After filtration by pressure filter, the filter cake has a higher solid content and excellent separating ability. The basic principle of solid-liquid separation: when the mixed liquid passes through the filter medium (cloth),  the solid stays on the cloth, and gradually accumulates on the cloth to form the filter cake, while the pure liquid can penetrate filter cloth. After filtration, we can get clear and transparent, high purity raw material-sodium silicate, which can ensure high quality raw material can provide to produce silica gel.

The Technology Center of Shandong Sinchem Silica Gel Co., Ltd. is equipped with TriStar II3020, manufactured by American Micromeritics Instrument Corp., which is a fully automated porosity analyzer. It can be used to conduct isothermal adsorption and desorption test, and to test the specific surface area, micropore volume and area distributions, mesopore pore volume and area distributions, total pore volume, etc.. Three silica gel samples can be analyzed simultaneously to improve efficiency. The analyzer can provide a full adsorption curve, desorption curve, BET and Langmuir specific surface area, average pore size and total pore volume in 1Pa, BJH mesopore value, large pore volume, size distribution and total pore volume.

Silica production system requires a great quantity of energy. The primary responsibility of power plant is to provide sufficient steam pressure and heat to dry silica products so that we can provide customers goods with stable quality and controllable water content. The power plant also can serve other electric equipments. Sinchem power plant is designed, operated and maintained strictly in line with National Electrical Operation Specification. We apply environmental friendly and high-efficient 75T/H circulating fluidized bed (CFB) boiler to achieve sustainable development and to become green chemical industry.
