Products Description
The waste alkaline water of the chemical plant is used as an alkaline activator, and the silicon slag of the plant is mixed to prepare alkali slag cement. By optimizing the amount of waste alkaline water and silica slag, alkali cementitious materials with good strength development and normal setting time can be prepared, which can effectively reduce the cost of alkali cementitious materials. In addition, it is found that in addition to the C-S-H gel, the hydration products of this alkali cementitious material include hydrated calcium aluminosilicate Ca(Al2Si2O8) @4H2O, calcium sodium aluminosilicate (Na,Ca)Al3Si5O16, two insoluble zeolite minerals.

Products cooperation picture
1.Method for recycling waste silicon slag discharged in zirconia dichloride production. Resource utilization method of waste residue discharged during the preparation process of zirconium compounds. It is characterized in that the waste silica slag is first converted into sodium silicate aqueous solution, and after filtration, the filtered residue is directly used as a raw material for the preparation of zirconia dichloride products; The filtrate is crystallized, the crystallization product is filtered, the resulting filter cake is dried, and all of them are made into 4A molecular sieve products, and the waste silica slag is completely recycled. It provides a method for the complete resource utilization of waste silica slag discharged from the production of zirconium dichloride with simple operation steps. It avoids the waste silica slag discharged in the production of zirconium dichloride in the prior art, which is the environmental pollution of soil, water and atmosphere. It significantly reduces the production cost of zirium dichloride, improves the economic benefits of zirconia dichloride production enterprises, and promotes the development of zirconium dichloride industry.
