Preparation of silicon powder Technology Articles | January 11 nike cortez ultra moire schweiz , 2012
The silicon metal is a hard brittle material. In the grinding process, residue can not be effectively controlled and the problem of over-grinding is serious, it results in product wastage, high production costs and product particle size of non-compliance and makes the products with no competitiveness.


This persistent problem has been plagued the majority of silicon production enterprises and business owner over the years.


There are many was using silicon blocks as raw materials to make silicon powder. Which is better, the application is more Raymond Law, Law on the roller, grinding method and the red rotating disk method. Equipment used in the corresponding law nike cortez schweiz , Raymond, roller machine, plate mill (also known as vertical mill) and washed melody. On milling theory perspective, the first three are squeezed crushing, crushing the latter is the impact on its structure, differ greatly, have their own characteristics nike vapormax blau schweiz , advantages and disadvantages.


Silica reactivity is involved in a chemical reaction to form products. Good performance of the activity of two aspects: First, responsive, stable, and easy to control; second reaction is complete, the unit consumption is low, the synthesis of silica fume 1t methylchlorosilane low consumption, in order to obtain high activity of silica nike vapormax herren schweiz , the system must take the high block method, the chemical composition of silicon blocks, environmental conditions and methods Preparation of silica fume have reached the optimum level. In fact, the milling process on the silica activity is also great. Standards to determine the activity of silica fume are: silica microstructure, surface area, particle size distribution and production of the results.


Meet the requirements of the chemical composition of silicon metal in the refining process has been the best micro-structure, in order to ensure their own participation in the best reaction activity. It must try to reduce the milling time of its microstructure degradation nike vapormax damen schweiz , reducing the grain size and grain deformation between the groups, the vast majority of micro-silica fume to maintain the original structure, in order to maintain or enhance its activity. Four methods, the best method to spin red, because the method is to use the volley hit the silicon block their way to make the weakest link in the body follow the fragmentation, there is no structural deformation caused by squeezing.


Silica fume surface area is involved in an important indicator of the ability of chemical reactions. Greater than the surface area of silica fume, the contact area with the larger methyl chloride nike vapormax schwarz schweiz , the higher the reactivity, the higher the utilization of silicon, the lower unit consumption; therefore, to determine the surface area in metal powder is an important indicator of the activity
