| titleOfInvention | A kind of method that calcium chloride prepares submicron solid spherical calcium carbonate |
| abstract | The present invention proposes a method for preparing submicron solid spherical calcium carbonate from calcium chloride. The method uses calcium chloride solution as raw material, adopts electrochemical-complexation reaction technology to prepare glycine complex calcium, and then undergoes carbonization reaction with CO 2 Submicron solid spherical calcium carbonate is obtained. In the method, the preparation of sub-micron solid spherical calcium carbonate is mainly realized by controlling the conditions such as DC voltage, complexation reaction temperature, complexation reaction pH value, carbonization reaction temperature, CO2 flow rate, carbonization conductivity, etc. The invention solves the problem of mine tailings or carbonization. The recycling and utilization of the residues of marble corners is an important means to realize "recovery of heavy calcium carbonate - purification of calcium - preparation of functionalized calcium carbonate". The main features are the use of waste residues, no high temperature calcination, the use of clean CO 2 realizes ecological internal circulation, which is a method for clean production of sub-micron solid spherical calcium carbonate powder materials. Realize the efficient and comprehensive utilization of the calcium carbonate industry, and solve the ecological and environmental protection problems that restrict the development of the calcium carbonate industry. |
