How do manufacturers test tires?

How do manufacturers test tires? Tire design determines the relevant basic indicators of the tire (such as specification, size, bearing capacity, pattern, etc.), on this basis, tire R&D engineers select the appropriate tire structure, frame material, rubber formula, size, pattern on the basis of scientific calculation, (It is now possible to directly generate tire design drawings directly with the help of computer series and big data analysis). How the tires produced according to this design plan behave in the process of use [...]

What is the difference between natural crystal and quartz

What is the difference between natural crystal and quartz Natural crystals belong to the crystalline minerals of quartz. The main ingredient is silica. Due to various impurities in quartz, it is classified as different colors. However, natural crystals belong to quartz, but there are still some differences between them. Quartz is a mineral resource with very stable physical and chemical properties. The crystal belongs to the oxide mineral of the cubic system, namely low temperature quartz (a-quartz), which is the most [...]

Diamond wire loop cutting machine

Diamond wire loop cutting machine What is diamond wire loop saw? The diamond wire loop is a flexible cutting tool that consolidates diamond on the annular steel wire substrate. It moves in one direction during cutting, and the cutting line speed is 40-60 m/s. The diamond wire loop can realize various precise and efficient cutting, such as Cutting of silicon crystal, sapphire, precious wood, graphite, magnetic materials, etc. the wirecutter The traditional reciprocating cutting requires constant reversing, so the line speed is limited [...]

Introduction to the cutting process of ceramics

Introduction to the cutting process of ceramics In major markets, the production of ceramics has always been in short supply. What is ceramics and what are its characteristics? Ceramic materials refer to a class of inorganic non-metallic materials made of natural or synthetic compounds through shaping and high-temperature sintering. It has the advantages of high melting point, high hardness, high wear resistance and oxidation resistance. It can be used as structural material and tool material. Because ceramic also has some special [...]

Application of diamond wire loop in graphite industry

Application of diamond wire loop in graphite industry At present, the graphite industry has been developing rapidly, so what is graphite? Graphite is an allotrope of carbon. It is a gray-black, opaque solid with stable chemical properties, corrosion resistance, and is not easy to react with chemicals such as acids and alkalis. Combustion in oxygen produces carbon dioxide, which can be oxidized by strong oxidants such as concentrated nitric acid and potassium permanganate. Can be used as anti-wear agent, lubricant, high-purity graphite is [...]

12-inch semiconductor wafers are in short supply

12-inch semiconductor wafers are in short supply The history of semiconductor silicon wafer development: it started in the United States, and Japan came later Semiconductor silicon wafers started in the United States, and MEMC has led the development of technology and set a number of global firsts. The semiconductor industry originated in the United States, and the same is true for semiconductor silicon wafers. In 1956, Monsanto Chemical Company established Monsanto Electronic Materials (MEMC Electronic Materials, MEMC), responsible for the production of [...]

Classification of semiconductor silicon wafers according to different parameters

Classification of semiconductor silicon wafers according to different parameters Semiconductor Silicon Wafer is the basis for manufacturing silicon semiconductor products and can be classified according to different parameters. According to different sizes (diameters), semiconductor silicon wafers can be divided into 2 inches (50mm), 3 inches (75mm), 4 inches (100mm), 5 inches (125mm), 6 inches (150mm), 8 inches (200mm), 12 inches Inch (300mm), under the influence of Moore’s Law, semiconductor silicon wafers are constantly developing in the direction of large size. Currently, [...]

Silicon wafers are the most in-demand semiconductor material

Silicon wafers are the most in-demand semiconductor material   Silicon wafer is an important semiconductor material, with a scale of over 10 billion US dollars. Semiconductor materials are a class of electronic materials with semiconductor properties (conductivity between conductors and insulators) that can be used to make semiconductor devices and integrated circuits, and are the basis of the semiconductor industry. The research on semiconductor materials began in the 19th century and has developed to the fourth generation of semiconductor materials, and each generation [...]

Semiconductor industry chain

Semiconductor industry chain Semiconductor silicon wafer is the upstream of the semiconductor industry chain and the core material for making chips. It runs through the whole process of chip making. The quality and quantity of semiconductor silicon wafers are not only the key materials for making chips, but also restrict the development of the downstream terminal industry.   In the silicon wafer industry chain, the upstream is the raw material silicon mine, the midstream is the silicon wafer manufacturer, and has strong [...]
