| titleOfInvention | A kind of production system of toothpaste grade sodium monofluorophosphate, preparation method and component thereof |
| abstract | A production system, preparation method and components of toothpaste-grade sodium monofluorophosphate, the sodium monofluorophosphate and the preparation method thereof can precisely control the content of sodium monofluorophosphate, free fluorine content and pH value, and prepare The product has high purity and the method is easy to operate; the sodium monofluorophosphate production system of the invention provides technical support for the preparation method of sodium monofluorophosphate in the invention, which specifically includes a raw material mixing and preparing device, a melting reaction furnace and a particle size control device, and The transfer silo and the transfer silo elevator are used for material transfer on the production line, in which the feed end of the raw material mixing and dispensing device is used to put sodium hexametaphosphate, sodium fluoride and phosphorus pentoxide in different parts by weight and mix the three Fully mixed, the discharge end of the raw material mixing and preparation device is connected to the melting reaction furnace, and the condensed sodium monofluorophosphate is screened by the particle size control device to screen out the finished product with qualified particle size; the transfer silo elevator is used to lift the transfer silo; Material transfer between devices. |
