Graphite powder for high temperature performance can be used for continuous casting graphite powder, graphite powder mold detergent, graphite crucible, graphite powder refractory bricks, lubricants, grease production. In the foundry industry, casting in the casting process is carried out in high temperature environment. In order to make the casting at high temperatures without deformation and not broken, it is necessary to join the casting graphite powder. Casting graphite powder can withstand forging high temperature and cast surface smooth, non-sticky sand to ensure casting quality.         Graphite powder crucible, graphite powder refractory bricks are added graphite powder so that they have a high temperature properties. The shortcoming of commonly used lubricants and grease is that they fail to withstand high temperatures. And they can not achieve lubrication property in high temperature. In the process of producing lubricating oil and grease, if dding graphite powder, it can not only increase the lubricating oil and grease lubrication performance, but also improve the degree of high temperature resistant.         Generally, rubber is insulated. If want for conductive need, adding some conductive materials is required. Graphite powder has excellent electrical conductivity and lubrication release. To process graphite into graphite powder, it will be with excellent lubrication and conductive properties. The higher purity of graphite powder, the better conductivity will achieve. We Hongwu International Group Ltd, with HWNANO brand, is a high-tech enterprise focusing on manufacturing, research, development and processing of nanoparticles and nanopowders.

  • Spherical  Zinc Oxide ZNO Nanostructures Application
    Spherical Zinc Oxide ZNO Nanostructures Application
    Spherical  Zinc Oxide ZNO Nanostructures Application     Compared with ordinary zinc oxide, Zinc Oxide ZNO Nanostructures has many other excellent performance. At present the main application areas are rubber products, high-grade paint, ink and paint, sunscreen and anti-ultraviolet fabric, sewage treatment,etc.   1. Zinc Oxide ZNO Nanostructures in Rubber Industry   ZnO nanopowder is the most effective inorganic active agent and vulcanization accelerator in rubber industry.  Zinc Oxide ZNO Nanostructures with small particle size 20-30nm, larege specific surface area, good dispersion, loose, porous, good liquidity and good affinity with rubber, easily dispersed whilc melting, low heat plastic material, breaking small deformation , good elasticity, can improve the material process performance and physical properties, thus it's used in the manufacture of high-speed wear-resistant rubber products, such as aircraft tires, high-class passenger car radial tire, with performance of anti-aging, anti-friction fire, long life, and greatly improves finish, mechanical strength, temperature and aging resistance of rubber products,especially wear resistance.  In addition, Zinc Oxide nano as a vulcanization system in the rubber system, whose additive is high.The large specific gravity and  filling amount of ordinary ZnO, whose influence on its material density, product life and energy consumption is detrimental. However, the use of Nano grade Zinc Oxide, the amountis only 30% -50% compared to the ordinary one,which reduces the cost of production, and the performance in the tensile properties, heat, aging, etc are far superior to ordinary zinc oxide powder.   2. Zinc Oxide ZNO Nanostructures in Ceramic industry   Because of very small particle size, large specific surface area and high chemical properties,nano ZnO can significantly lower the sintering densification of materials, save energy, make the ceramic material composition densification, homogenization, improve the performance of ceramic materials, the reliability of its use. Controling the composition and structure of materials on the structural level of nano materials is conducive to give full potential performance of ceramic materials. In addition, because the particle size of ceramic material determines the microstructure and macroscopic properties of ceramic materials, if the particles of the powders are uniformly packed and the sintering shrinkage is uniform and the grain grows uniformly, then the smaller the particle size, the smaller the resulting defects, and the higher the strength of the prepared material, which may result in some unique performance that large particles do not have.   3. Nano Zinc Oxide in Other Areas With the deepening understanding of the performance of nano Zinc Oxide, its applications continue to expand, for example, in the traditional coating technology, adding nano ZnO can further improve the protective capacity, making resistance to atmospheric damage and anti-degradation, color,etc.With a certain percentage of Zinc Oxide nanopowder added to the propionic acid coating, it can be made into excellent nano antibacterial coating. Making use of the sensitive properties of nano ZnO, can produce a high sensitivity gas alarm and hygrometer.           As a new type of semiconductor materials, Zinc Oxide ZNO Nanostructures has become a new type of high-performance fine inorganic products in the 21st century. At present, researchers at home and abroad have developed a variety of methods to prepare various forms of nano zinc oxide products and achieve a lot. However, there are still some shortcomings such as high cost, complicated process and difficulty of industrialization in the preparation method. In addition, the research on the structure and application performance of nano ZnO is not deep, so the follow-up research will focus on the development of simple, high-efficient and easy industrial production methods. With the further study of the material structure on its optical, electrical, magnetic and acoustic properties, it is expected that with the continuous improvement of the preparation method of nano zinc oxide, the nano-size effect of nano-sized oxides, and the study will have a full-speed development stage. by Jemma
  • Silicon Carbide nano particle
    Silicon Carbide nano particle dosage influencing on composite friction performance
    Silicon Carbide nano particle dosage influencing on composite friction performance       For Silicon carbide nano particle is with Moh’s hardness about 9.2 which is a hard material. With its hardness, SiC nano powder is suitable to be additive for composite material and improve their toughened and strengthened.        For SiC nano additive has different influence to the relative density, hardness, electrical conductivity and friction and wear properties of the composites. Generally the relative density of the composites decreased with the increase of the content of nano SiC particles. The hardness of the composites increased with the increase of the content of SiC nano particles, but when the nano  SiC particles agglomerated, the hardness increased . However the content of silicon carbide nano powder affect to the conductivity of material is opposite. When the content of  SiC nano particle increase the conductivity of the composite decreases. According to some study when the content of SiC particles is about 0.5% -3%, the wear rate of the composites decreases with the increase of SiC content. When the SiC content is more than 3%, the wear rate of the composites increased with the increase of the content of  SiC nano-particles. The abrasive wear and the friction coefficient decreased with the increase of the SiC content.
