Great use of quartz sand powder!

quartz sand powder for coating and painting


High purity quartz sand powder has special optical properties that conventional SiO2 does not have. It has strong ultraviolet absorption and infrared reflection characteristics. The addition of silica powder to the coating can form a shielding effect on the coating, achieve the purpose of anti ultraviolet aging and thermal aging, and increase the thermal insulation of the coating. The hardness and adhesion of the UV curable coating are improved and the absorption of UV radiation is weakened by doping high-purity silicon powder into the UV curable coating. Thus, the curing speed of UV curable coating is reduced. High purity silica powder has a large specific surface area, shows great activity, and can form a network structure when the coating is dry. At the same time, the strength and finish of the coating are increased, the suspension of the pigment is improved, and the color of the coating can be kept unchanged for a long time. The amount of fillers is very important to the viscosity of paints and coatings. The use of silica micro powder as functional fillers in paints and coatings can not only greatly reduce the amount of resin, but also greatly reduce the production cost, and improve the quality of paints and coatings, so that paints and coatings can achieve the goals of low shrinkage, low viscosity, high addition, high wear resistance and good storage.

Silicon powder for electronic packaging


Silicon micro powder as filler can greatly improve the rigidity, wear resistance, weather resistance, impact resistance, compression resistance, tensile resistance, fire resistance, good arc insulation resistance and UV radiation resistance of products. The thermal conductivity and expansion coefficient of epoxy resin filled with silica powder are small. The filling rate of epoxy resin used as the substrate and package of microelectronic components can reach 90%. It can be used as the ideal substrate and package material for large-scale and super large-scale integrated circuits First of all, the quartz powder and the resin are stirred to form a film uniformly, the resin content is small, and the fluidity is the best. The highest weight ratio of the silica powder can reach 90.5%, so the electronic components with excellent performance can be produced. Secondly, the stress concentration of the plastic packaging material made of spheroidization is the smallest and the strength is the highest. Therefore, when the spherical powder plastic packaging integrated circuit chip, the yield is high, and it is not easy to produce mechanical damage in the process of transportation, installation and use. Third, the small friction coefficient of the spherical powder and the small wear on the mould can double the service life of the mould and reduce the cost a lot.

Silica sand powder for electronic ink


High purity silica powder has good fluidity and lubricity, which can achieve better dispersion, suspension and stability. When silica powder is used in ink and pigment, it can make the amount of ink and pigment is small, but the covering power is high, the luster is good, the resin particle size is fine, the film is continuous, uniform and bright, and the film layer is thin, so that the printed image is clear. If it is used in UV ink, it can accelerate its curing speed. At the same time, due to The fine and even dispersion of filler can eliminate the shrinkage and wrinkling of ink film. Will make ink color brilliant and luminous, printing a more beautiful image.

Silicon powder for advanced ceramics


As a kind of energy-saving mineral raw material, high-purity silicon micro powder is used in special high-temperature resistant ceramic materials, which also has ideal effect on reducing firing temperature and improving yield. As a carrier and filler, silicon micro powder is widely used to improve the toughness and smoothness of ceramic products. The high temperature resistant ceramic matrix composite material made of silicon micro powder and advanced composite materials based on high-performance resin and ceramics is an ideal heat-resistant tile material for aircraft, rocket, satellite, spacecraft and other aerospace vehicles. It is used in precision ceramics, electronic ceramics, advanced ceramics, artificial mullite materials, enamel glazes and special refractories. It has excellent dielectric properties, low coefficient of thermal expansion, good electrical insulation, multi-layer protective layer formed in oxidation, good mechanical properties, high temperature and oxidation resistance, and can also solve the problem of brittleness of ceramics. After adding silica powder into the ceramic, it is more compact, heat-resistant and cold fatigue resistant, and its strength is greatly improved. The special refractories with silica powder have good fluidity, sintering, combination and filling porosity, which make the special refractories have the characteristics of dense structure, high strength, wear resistance and corrosion resistance. The excellent physical properties, high chemical stability and unique optical properties of silica powder have become the most basic, important and key raw materials in many high-tech fields.

Optical fiber raw material silicon powder


Optical fiber communication is a modern means of communication, which can provide high-capacity, high-speed, high-quality communication services. The main component of optical fiber used in optical fiber communication is optical fiber. The fused silica powder has unique properties such as smooth surface, large specific surface area, high hardness, stable chemical properties, small expansion coefficient, good rolling performance and excellent mechanical properties. With the rapid development of microelectronics industry, it is required not only to be ultra-fine, but also to have high purity and low radioactive element content, especially for the particle shape. Because of its excellent properties, such as high dielectric, high heat resistance, high moisture resistance, high filling capacity, low expansion, low stress, low impurity, low friction coefficient and so on, silicon micro powder has become a high-quality raw material for the manufacture of optical fiber.

Cosmetic raw material silicon powder


Silicon micro powder is manufactured by an innovative process, which can obtain narrow particle size distribution and large surface area, with the following unique properties: its smaller average particle size determines its good smoothness; its narrower particle size distribution determines its good fluidity and tactility; its larger volume determines its cosmetics formula more economical. Its large specific surface area enables it to have a good absorption function, which can be used for perfumes, nutrients and protective chemicals. Silicon dioxide, used in lipstick, powder and foundation cream, has the following characteristics: good dispersion and compatibility in oil phase; good affinity to skin; good hydrophobicity, which can enhance the durability of makeup. Silica micropowder is used in liquid to enhance its thickening and thixotropic properties. It plays a role of suspension and redispersibility in liquid phase. It can improve the mobility and storage stability in powder products such as flour cake, thereby preventing caking. Because of its high specific surface area, it can also act as adsorbent and carrier, and can adsorb gas, liquid and solid substances.

Silica powder for filling oil paste thickener for optical fiber cable


In the long-term use of optical cable, due to the infiltration of moisture and moisture, the transmission performance of optical cable will deteriorate, or even can not be used. In order to prevent the invasion of moisture and the damage of optical fiber caused by the friction between the fabricated optical fiber, in addition to filling the optical fiber oil paste in the optical fiber gap, the optical fiber oil paste also needs to be coated on the optical fiber. The company's high-purity silicon dioxide can replace the imported raw materials, so not only the cost is low, but also the performance indicators have reached the level of imported similar products. The oil paste filling thickener with high-purity silica as the main raw material of our company is used for the production of optical fiber cable and cable insulation filling oil paste: good thickening, thixotropy, high penetration, normal temperature construction, stable colloid, high drop point, small oil separation, excellent high and low temperature performance, wide range of use temperature, giving hydrophobicity.

Precision grinding powder silicon micro powder for optical devices and photoelectric industry
