Whetstone sintered corundum (ruby) : A kind of microcrystalline corundum product sintered at high temperature. It has a compact and delicate structure and high hardness and strength.
The products are rosy red. The products are small grinding wheel type whetstone, standard type whetstone and grinding head type whetstone. When grinding the workpiece, it can maintain sharp edge and stable geometry for a long time.
It is suitable for forming and grinding of instrument industry, precision parts, micro cutting tools, tools and precision abrasive tools, etc. The precision surface roughness of machining can reach about 0.05μm.
Product SPECIFICATIONS: flat sand wheel whetstone with diameter less than 100 for small grinding wheel type, whetstone with various geometric shapes less than 200*50*25 for standard type, whetstone with diameter less than 25 for grinding head type.
Grinding method
About diamond grinding paste, particle size from W40 to W0.5. W40 is the coarsest, with a large amount of grinding, and W0.5 is the smallest. It is used for polishing, and it does not anneal, and it can also grind the hard knife.
Method of use:
The coarse W40 abrasive paste applied to borotartar can accelerate and increase the grinding amount without annealing.
Then, AFTER the rough grinding paste on the knife is cleaned, W0.5 grinding paste is applied to the ruby or natural jade for polishing, and the effect thrown out is a mirror.
Green silicon carbide, white corundum, brown corundum of these three kinds of whetstone hardness is not enough, coupled with a little coarse particle size, easy to grind out the cross, and the other three kinds of whetstone in polishing, grinding will not annealing.
If the particle size is greater than 1000, there is no difference. It mainly depends on the grinding paste used. When the grinding paste of W1.5 is applied to the ruby with 1000 mesh, its grinding effect is the effect of the grinding paste of W1.5, that is, the effect of the whetstone with 2500 particle size

**Abstract**
In March of this year, Zhejiang University developed the world's "lightest material" using graphene and other advanced materials. The breakthrough could revolutionize how we access digital content—imagine downloading a high-definition movie in just a second. This is made possible by the development of graphene modulators, which are expected to drastically increase internet speeds. One of the pioneers in this field is Professor Zhang Xiang, a Chinese-American scientist who has been at the forefront of graphene research.
Graphene, a two-dimensional material composed of a single layer of carbon atoms, has captured the attention of scientists and industries alike. Despite being discovered only a decade ago, it has already sparked a technological revolution due to its extraordinary properties. It is not only the thinnest and strongest material known to man but also an excellent conductor of heat and electricity. Its unique characteristics make it a promising candidate for a wide range of applications, from ultra-fast electronics to next-generation solar cells.
The journey of graphene began with theoretical predictions, but in 2004, physicists Andrei Geim and Konstantin Novoselov successfully isolated it from graphite, proving that it could exist as a standalone material. Their groundbreaking work earned them the 2010 Nobel Prize in Physics. Since then, researchers have continued to explore its potential, leading to numerous innovations and discoveries.
Graphene is known for its incredible strength, being 100 times stronger than steel, and its exceptional electrical conductivity, allowing electrons to move at nearly the speed of light. It is also almost completely transparent, with a light transmittance of over 97%, making it ideal for use in touchscreens, solar panels, and flexible electronics.
In China, graphene research is advancing rapidly. Institutions such as the Chongqing Institute of Green and Intelligent Technology have made significant progress in developing scalable production methods, reducing costs from 5,000 yuan per gram to just 3 yuan. These advancements have opened new doors for commercial applications, including transparent electrodes, energy storage systems, and high-performance microchips.
Experts predict that within the next few years, graphene-based products will become more common. From foldable smartphones to ultra-light aircraft, the future looks bright for this remarkable material. As preparation technologies continue to improve, the dream of widespread graphene applications is becoming a reality.
