At the 2nd China (Zhengzhou) International Abrasives Grinding Exhibition, Beijing Guoruisheng Technology Co., Ltd. attracted many exhibitors to watch with high-tech diamond products. The reporter of China Superhard Materials Network visited Guoruisheng Technology Co., Ltd.
As a Sino-Japanese joint venture, Beijing Guoruisheng Technology Co., Ltd. specializes in R&D, production and operation of ultra-precision polishing materials. The company was established in June 2001 and is located in Beijing Zhongguancun Science and Technology Park. It is a high-tech enterprise recognized by the Beijing Municipal Government. It mainly develops, produces and sells ultra-precision polishing films (abrasive paper), grinding fluids, polycrystalline diamond micropowders, nano-diamond micro-powders and TFT-LCD polishing cloths. It is widely used in optical communication, semiconductor, LED, LCD, micro-motors. , hard disk heads, metal rollers and automotive crankshafts and other industries.
Abrasive sheet The abrasive sheet utilizes the latest ultra-precision coating technology developed in the world to uniformly disperse the micron or nano-scale diamond micropowder and the new polymer material, apply it to the surface of the high-strength film, and then process it through a high-precision cutting process. Mainly used in optical communications, hard drives, metallographic analysis and other industries.
The product utilizes a proprietary formulation process to ensure uniform dispersion of abrasive particles; stable product quality and small differences between batches; high grinding force characteristics of fixed abrasives such as grinding wheels, and polishing precision of free abrasives such as polishing fluid; It has good strength and flexibility, and can achieve the ideal surface polishing effect; it is suitable for dry polishing, and it is also suitable for polishing with water or oil as grinding medium.
Ultra-precision polishing belt The ultra-precision polishing belt utilizes advanced precision coating technology to uniformly disperse micron, sub-micron or nano-scale grinding micro-powder (diamond, silicon carbide, alumina, etc.) and new polymer adhesive materials, and apply it to the surface of high-strength film. And then processed through high-precision cutting process.
The product is stable in quality and can achieve high grinding consistency; high grinding force, can achieve precise polishing effect; good strength and flexibility, can achieve ideal curved surface polishing effect; suitable for dry polishing, also Suitable for polishing with water or grinding oil as grinding media.
Precision grinding belt The precision grinding belt is used to implant fine abrasive grains on the high-strength film by means of high-voltage electrostatic field force, so that the abrasive grains can be evenly distributed, which can provide higher grinding efficiency and bright and fine polishing effect. The abrasive grains include alumina, silicon carbide, and the like. Suitable for grinding and polishing materials of different hardness.
The abrasive particles are oriented and the surface of the product is sharp, ensuring the best grinding performance of the abrasive belt; the surface abrasive particles are evenly distributed, combined with special binder to prevent deep lines and irregular lines. Good chip removal capacity, not easy to block. Water-resistant and oil-resistant polyester base for wet grinding. Durable for continuous durable grinding and reduced production costs.
Precision polishing cloth Precision polishing cloth is made of internationally advanced ultra-precision coating technology and advanced resin bonding technology to uniformly apply precision grinding powder to high-strength and wear-resistant textile fabrics. The fine groove on the surface of the cloth base is a good chip flute, which can improve the grinding efficiency; the high-strength, wear-resistant cloth base, combined with advanced resin bonding technology, can prevent the abrasive from falling off and scratch and clean the workpiece. The chamber is polluted; the gap of the cloth base can absorb more grinding medium (such as water), and the surface of the workpiece will not be scratched due to high temperature during grinding; the cloth base is soft and elastic, which can better be applied to the surface of the workpiece, thereby improving Grinding efficiency and grinding quality.
Detonation polycrystalline diamond powder The detonation polycrystalline diamond micropowder is synthesized by an explosion method, and its particle crystal structure is very similar to that of the natural Carbonado, and is combined into a polycrystalline structure by unsaturated bonds. Compared with single crystal diamond, polycrystalline diamond has more crystal edges and grinding surfaces, each of which has cutting ability and therefore has a high removal rate. Polycrystalline diamond has toughness and self-sharpness. During the polishing process, coarse particles will break into smaller particles, which can avoid scratching the surface of the workpiece, ensuring the surface quality of the workpiece and improving the grinding efficiency. Some of the high quality requirements of the product process show its unique advantages.
Nanodiamond Nano-diamond is produced by detonation synthesis of high-energy explosives under negative oxygen conditions. The ultra-high pressure and high temperature conditions necessary for synthesizing diamond are generated at the moment of detonation, and the free carbon atoms generated by the explosive form nano-scale diamond particles. Unlike conventional hydrostatic synthetic diamonds, nanodiamonds have no spherical edges and a single grain size of only a few nanometers.
The product has high dispersibility and good dispersion stability; it has various dispersion sizes and can meet different particle size requirements; it can achieve ultra-high purity, the main impurity content is below 10ppm; ultra-precision polishing effect, surface roughness is less than 1nm Excellent wear resistance, corrosion resistance and thermal conductivity.
Single crystal diamond powder The single crystal diamond micropowder is made of high quality diamond as raw material, processed by ball milling, grading and purification treatment. All products are in line with ultra-pure technical specifications. According to international practice and actual demand, the company has formulated the supply specifications of single crystal diamond micropowder products, and can also adjust the particle size, distribution, purity and other indicators to a certain extent according to the specific requirements of specific customers.
The product is a high-quality single crystal diamond material, ensuring the high quality and stability of the micropowder; narrow particle size distribution and ultra-high content, ensuring grinding and polishing efficiency, avoiding the occurrence of abnormal scratches; ultra-high purity, the main impurity content is 100ppm The following; complete particle size specifications, sub-nano, sub-micron, micro-scale single crystal micropowder. Strict testing means to ensure batch-to-batch stability.
Polycrystalline diamond slurry Polycrystalline diamond slurry 100% uses the company's own polycrystalline diamond micropowder, combined with a highly dispersible formula, can maintain high cutting rate and is not easy to scratch. The grinding rate of the product is stable and the polishing surface is consistent.
Guoruisheng is committed to supporting and promoting high-tech development, based on service, surviving on quality and developing on science and technology; continuously developing new products and providing high-quality products for precision grinding and polishing of high-tech components in time. Meet the needs of different industries and users. On the road of future innovation, the company will continue to contribute to the strong development of the super-hard materials industry with careful and meticulous attention to results, the pursuit of perfect work attitude and energy.
