Technical Field
[0001] The utility model belongs to the technical field of polyethylene wax oxidation reaction, in particular to a polyethylene wax oxidation reaction kettle. Background Art
[0002] Polyethylene wax, also known as polymer wax, is a chemical material. It is formed by ethylene polymerization rubber processing agent, and is in the form of white small micro beads or flakes. It has the characteristics of high melting point, high hardness, high gloss, and snow-white color. Its excellent cold resistance, heat resistance, chemical resistance and wear resistance make it widely used in many fields. In the application of polyethylene wax, it is necessary to oxidize the polyethylene wax to support a product with higher density, so a polyethylene wax oxidation reactor is required to complete the operation.
[0003] Polyethylene wax oxidation reactor is a device used for polyethylene wax oxidation reaction. Its main function is to react polyethylene wax with oxidant and other reactants under certain temperature, pressure and time conditions to prepare high-density oxidized polyethylene wax. Its structure includes a reactor body, a stirring device, a heating or cooling system, a feeding and discharging system, etc. Its principle is to place polyethylene wax and oxidant inside the reactor body, and then use a stirring device and a heating or cooling system to make the two fully react, and finally discharge them from the discharge port.
[0004] The existing polyethylene wax oxidation reactor requires the polyethylene wax to be melted first and then poured into the reactor body, which increases the time required for production. However, if the solid polyethylene is directly placed in the reactor body for melting, some of the polyethylene wax will deteriorate due to uneven heating. In addition, the existing polyethylene wax oxidation reactor is insufficient in pressure relief, which will lead to the risk of overpressure inside the reactor body during the production process. Therefore, a polyethylene wax oxidation reactor is proposed to address the above problems. Utility Model Content
