• Akira Akira relates to a new manufacturing method and equipment for silicon soda. More specifically, the molar ratio between aluminum and silica
• the method for producing silica soda is to dissolve a readily soluble silica drum raw material represented by clay into an aluminum solution (: mainly caustic soda).
• an aluminum solution mainly caustic soda
• silica sand and alkaline mainly charcoal soda
• Such powers have the following disadvantages in conventional methods: In other words, although the energy required for production by the wet method is small, it is colored due to the impurities contained in the silica raw material.
• the inventor of the present invention made an intentional examination, using a special ⁇ arrangement, countering the conflict between the al power and the Tadashi, and making a state of physical elimination.
