Brief
Introduction
The super fine silica/quartz/crystal micro powder is out of
super purified 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(SinoSi) 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
powder 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 powder 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, silicon
micro powder applies to both large-scale components and small-scale
precise electrical components.
According to
our recent research and wide application, the abovementioned
properties as well as its perfect effect become quite obvious
and extremely successful in the pouring-sealing of integrated
circuit chip transistors, magnetic head, and etc. It is proved
to be the most applicable filling material.
