Silica powder, as a fine powder material, has become an indispensable and important material in modern industry with its unique physical and chemical properties and wide application fields. This article will introduce the characteristics, production process, and downstream applications of silica powder in detail, and focus on the 600 mesh silica powder ultrafine grinding machine .
Introduction of Silica Powder
Silicon powder is mainly made of silicon. It is an environmentally friendly inorganic non-metallic functional powder new material obtained by selecting natural fused crystal quartz or fused quartz as raw materials and deep processing through multiple processes. Its main component is silicon dioxide, and the crystal structure can be in various forms such as cubic, hexagonal and orthorhombic. The particle size of silicon powder is generally between a few nanometers and tens of microns. According to the particle size, it can be divided into nano silicon powder and micro silicon powder.
Silica powder has good chemical inertness and physical properties, such as acid and alkali resistance, oxidation/reduction resistance, salt spray resistance and electrochemical stability, high hardness, high thermal stability, high insulation, low expansion, UV light impact resistance, etc. These excellent properties make silica powder have a wide range of application prospects in many fields.
Downstream applications of silicon powder
Rubber and plastic industry: Silica powder can enhance the hardness, strength, wear resistance and aging resistance of rubber and plastic, and can also improve heat resistance, cold resistance and UV resistance, while acting as a filler to reduce costs.
Paint industry: Silica powder can increase the hardness, glossiness and wear resistance of paint and prevent the paint from cracking and cracking.
Electronics industry: Silicon powder can be used to prepare semiconductor materials, optical fibers, optical films, capacitors, batteries, solar cells and other electronic components.
Cosmetics industry: Silica powder can be used as a filler in cosmetics to increase texture and consistency, improve transparency and gloss, and is used to prepare sunscreen, conditioner, facial cleanser, etc.
In addition, silicon micropowder also has important applications in glass, ceramics, fine chemicals, advanced building materials and other fields. Especially in epoxy molding compounds, silicon micropowder acts as a key filler to reduce the linear expansion coefficient, increase thermal conductivity, and reduce the dielectric constant.
Production process of silicon micropowder
The production process of silica powder is delicate and complex to ensure that its purity, particle size and hue are just right to meet the stringent requirements of various application fields. The main production processes include coarse crushing, impurity removal, fine grinding and classification.
Coarse crushing: Large pieces of quartz minerals need to be crushed by jaw crusher first to reduce the particle size of the original ore for subsequent processing. Impurity removal: Impurities in the ore are removed by physical and chemical means such as color sorting, flotation, and magnetic separation.Fine impurity removal also includes pickling and calcining. Pickling can remove metal ion impurities, while calcination removes lattice impurities through sintering.
Fine grinding: Use a 600-mesh silicon micropowder ultrafine grinder to grind to meet the qualified particle size requirements.
Classification: The finely ground silicon powder needs to be classified by air flow to ensure that the particle size distribution meets the requirements.
