Spherical Silica Sand - SS/PS/SS

The silica sand has two kinds, natural silica sand and spherical silica sand. The normal-purified silica sand is out of super fine and high quality natural silica ore by applying special hi-tech methodology in the process of preliminary selecting, fragmenting, grinding, purifying, dehydrating, classifying and so on. This technology enabled the sino surplus international limited the first mover as well as the leading producer and research institute in this industry. This product enjoys unmatched fineness, granularity, stability and know-how. The specific feature of free coarse granules and perfect chemical stability makes the super fine silica powder become the best filling materials and additive in comprehensive applications including paint-coatings, adhesive, sealants, silica gels and epoxy resins and etc.Because of its special properties and excellent characteristics the silica sand is widely used in areas of electronics, electrical apparatus, chemical industry, special micro motor, sealing of transistor and semi-conductor components, insulation casting of current transformer, voltage transformer, electronic transformer and dry-type transformer, epikote casting of high-tension cable connection, high-voltage insulator, high-voltage switch, insulation pipes and components of high-voltage electrical apparatus. The silica sand is also used in electric welding industry as protection coating. In addition, it acts well as epoxy powder coating and as the filling materials for arc resistant and weathering resistant surface painting. As the filling material for epikote, silica sand applies to both large-scale components and small-scale precise electrical components.
