Why use platinum ferroalloy instead of iron as electrode?
Silica (Silica) is widely used in paint, ink, plastic, rubber and cosmetics, are often added to increase the performance of silica, such as oil absorption, extinction, strengthen the mechanical... Etc., and can reduce the cost of...
General industrial grade silicon dioxide, because the preparation technology is different, can be divided into two types, one is dry, sintered (Fume Type), a wet precipitation type (Precipitated Type), and two of the surface area, the surface with hydroxyl (-OH) are the same, in general, the former the latter is more, less, the two surface has the tendency of hydrophilic, as for lipophilic polymer, such as paint, rubber... Etc.,... If the silica surface pre rendered hydrophobic, has a good effect.
Its surface properties must comply with the characteristics of the additives so that they can be dispersed evenly.
