Properties: FNG water resistant silicone is white or gray microporous granules, block and spherical. This product is a kind of processing and shaping by powder silica gel, except with ordinary silica gel adsorption performance, also has a good water resistance, low broken rate and long service life, etc.
Use: this product is mainly used for the dry air in the process of air separation, liquid air and liquid oxygen acetylene adsorption of preparation process, compressed air drying and all kinds of industrial gases, in petrochemical industry, electric industry, brewing and other industries do liquid absorbent and used as a catalyst carrier, used for water purification in water treatment.
Specification: according to the pore structure is divided into FNG-type A (pores) and FNG-C (coarse)
According to the particle size can be divided into 1-3mm; 2-4mm; 2-5mm; 4-8mm; 6-8mm; 8-10mm; 8-12mm, etc.
