As an inorganic powder, silicon micro powder is widely used in polymer materials. After surface modification, natural quartz takes silicon micro powder by quartz grinding mill, which has excellent characteristics such as high insulation, high thermal stability, low thermal expansion coefficient, acid and alkali resistance, wear resistance, etc. It can be widely used in electronic, electrical, glass fiber, rubber and plastic, paint, daily chemical and other industries.

Why the Surface Modification Treatment Should Be Used to Produce Silicon Powder from Natural Quartz

Silicon micro powder itself is a polar and hydrophilic material, which is different from the interface properties of polymer matrix, has poor compatibility, and is difficult to disperse in the base material. Therefore, it is usually necessary to modify the surface of silicon micro powder, and purposefully change the physical and chemical properties of the surface of silicon micro powder according to the needs of application, so as to improve its compatibility with organic polymer materials and meet its dispersion and liquidity needs in polymer materials.

Application field of natural quartz after obtaining silicon powder by quartz grinding mill

Silicon micro powder can be used in many fields, such as copper clad laminate, rubber, plastic, coating, epoxy plastic sealant, electrical insulation materials, adhesives, building materials, etc. As the filler of CCL, crystalline silicon micro powder can be used in industries with lower production requirements at a lower price, and can improve the thermal stability, stiffness, thermal expansion coefficient and other properties of CCL to a certain extent. Silicon micro powder has the advantages of small particle size, large specific surface area, good heat resistance and wear resistance. It can improve the wear resistance, tensile strength and modulus, high tear resistance and other properties of rubber composites. Silica micro powder can be used as filler in the coating industry, which can not only reduce the cost of coating preparation, but also improve the performance of the coating, such as high temperature resistance, acid and alkali resistance, wear resistance, weather resistance, etc.

Process Flow of Natural Quartz Using Quartz grinding mill to Produce Silicon Powder

Silicon dioxide (SiO2) has two forms: crystalline and amorphous amorphous, so SiO2 micro powder includes crystalline and amorphous states. In SiO2 crystal, each silicon atom is surrounded by four adjacent oxygen atoms and is located at the center of four O atoms. It combines with these four oxygen atoms with covalent bonds to form a three-dimensional network structure with silicon oxygen tetrahedron as the basic structure. The crystal structure of SiO2 is shown in the figure. Silica micro powder can be prepared from natural quartz or fused quartz through crushing, grinding, flotation, pickling, purification, high-purity water treatment and other processes.

In order to make silicon powder from natural quartz, a stable, efficient, energy-saving and environment-friendly professional quartz grinding mill is required. HLMX quartz superfine vertical roller mill of HCMilling(Guilin Hongcheng), as a professional quartz superfine mill, can efficiently grind natural quartz to produce silicon powder. With simple process flow and few system equipment, it is a rare equipment with high cost performance. Compact structure layout, small floor area, only 50% of the ball mill, can be arranged in the open air, low construction cost, and create more profit space for customers.
