Production of ceramic proppant to note the following seven elements

To the level of bauxite -based raw materials , dolomite , boric acid, bentonite, precipitated barium sulfate as a secondary raw material to manufacture Resin coated ceramic proppant , the effect of addition of various materials on the proppant performance . The results show that through rational design of various ratios of raw materials, improved granulation process and select the appropriate sintering temperature can develop excellent performance ceramic proppant . After the practice of industrial production , Ultra lightweight proppant confirming the production process design is feasible . Study the following conclusions:

    ( 1 ) According to Al203-Si02 binary phase diagram , select the level of bauxite -based raw materials, adding a certain amount of auxiliary materials can produce excellent performance of ceramic proppant , the process parameters are also exposed to the range of company equipment within ;
    ( 2 ) because of the small silica particles can be effectively filled in the gaps between the bauxite and other powder , in the firing process , due to their activity , is conducive to reduce the sintering temperature, while the amount of silicon powder also help to improve performance ;
