| titleOfInvention | Method for producing high-quality insoluble sulfur and sulfur product produced by method |
| abstract | The invention discloses a method for producing high-quality insoluble sulfur and a sulfur product produced by the method, and belongs to the technical field of sulfur production. The production method of the high-quality insoluble sulfur comprises the steps of preparing a semi-finished product of the insoluble sulfur with medium content by adopting a low-temperature melting method, and then carrying out extraction, secondary drying, sieving and oil-filling treatment to obtain the high-quality insoluble sulfur, wherein in the secondary drying treatment, the product obtained after extraction is uniformly mixed with a proper amount of stabilizer and then is dried together, the stabilizer is prepared from ammonium persulfate and ethyl sodium xanthate, and a certain amount of fatty alcohol polyoxyethylene ether is added into the stabilizer during oil filling. The production method can effectively improve the thermal stability and the dispersibility of the obtained insoluble sulfur, thereby ensuring the application effect of the insoluble sulfur. |
