Non-fluorine and acid-free separation of quartz feldspar is a major breakthrough in quartz beneficiation in recent years . Because of the similar physical and chemical properties of quartz feldspar, the traditional method of separating quartz feldspar requires a large amount of hydrofluoric acid to adjust the slurry, causing serious environmental pollution. Through the surface treatment of quartz and feldspar, the research group realized the separation of quartz and feldspar without fluorine and acid, and successfully purified the quartz sand with SiO2 content of only about 60% to 99.5% of SiO2 content, and recovered feldspar.
Fischer-Tropsch wax can be used in plastic processing, such as injection molding, extrusion and pelletizing industries. In the production process of masterbatch and modified plastics, Fischer-Tropsch wax contributes to the dispersion of fillers and excellent smoothness during mixing. It can be used as an external lubricant for PVC. The low viscosity can increase the production speed of the product. It helps to disperse the pigments and fillers during mixing. It is especially useful in the extrusion of high-viscosity systems. It is more than ordinary PE WAX. 40-50% less, and can significantly improve the surface gloss of the product. When using intense colors, the melted Fischer-Tropsch wax can effectively wet the dye and reduce the extrusion viscosity.
When used in the ink as a particulate powder, it can improve the wear resistance and wrinkle resistance of the applied material. When applied to the coating, it can have a wrinkling effect, and when used in a micro powder state, it can form a wrinkle effect of stripes and water lines. When powder coating resin is added, it plays a role of lubrication in the extrusion process, which can reduce screw torque, reduce energy consumption and improve production efficiency.
