Laser Particle Size Determination of Particle Size of Ceramic Powders
And in 2013 for the ceramic industry, ceramic machinery market prospects for the global construction demand remains strong, the main influence for our country's overall economic situation in the country. In 2013, the overall situation for the ceramics industry was not good nor bad. The current real estate regulation and control continues to continue, the ceramic industry production capacity significantly beat production. The pace of economic recovery in Europe and the United States is relatively slow, which is not good for the ceramic market. However, with the further promotion of China's construction, in 2013, a relatively loose monetary policy, China's overall economic growth is on the rise, China's ceramic products have a strong international competitiveness. It is expected that the overall development of our ceramics industry will be stable in 2013, and production will increase slightly, and it is estimated that it will remain near 5%.
After China's accession to the WTO, the Chinese market has become increasingly integrated with the world market. The international ceramics market has emerged with new features such as fierce competition in the market, gentrification in the market demand, and arts ; matching sales in the market , diversification in demand, and personalization . With the extraordinary development of China's ceramic industry, the development of ceramic products in China is facing a severe test. Firstly, low-price competition led to continuous reshuffle of the industry ; secondly, tariff protection policies gradually relaxed ; third, international giants used domestic OEM to seize competitive advantage ; fourth, export tax rebate policy controlled tile exports ; Fifth, the threat of anti-dumping was also very high. Serious . The existence of domestic ceramic enterprises competitiveness of China's ceramic machinery company's market share is still relatively dispersed, industry concentration is low, it is still difficult to form an effective competitive advantage in the international market. In recent years, although the ceramics equipment enterprises have achieved certain results in exports, they have not yet opened up the situation in major markets such as Europe and the United States.
Structural ceramics have superior strength, hardness, insulation, high temperature oxidation resistance and other characteristics. Under the extremely harsh environment or engineering application conditions, the high stability and excellent mechanical performance exhibited are gradually expanding in the material industry. Structural ceramics mainly refers to a large class of new ceramic materials that exert their mechanical, thermal and chemical properties. It can be used in many harsh working environments, and it has become the key to many science and technology. Special structural ceramics is an important branch of ceramic materials. It has high temperature resistance, high strength, super hardness, wear resistance and other properties. It has important applications in metallurgy, energy, machinery and other fields. Silicon carbide ceramics is one of the more important ones.
The preparation of ceramic materials usually goes through three processes: raw material preparation, blank formation and firing processes. In the relationship between the three elements of material science and engineering technology research, the physical and chemical properties of ceramic powders will determine the ceramics. The final microstructure and special properties of the material, and thus powder quality, is the basis for the preparation of high-performance ceramic materials. The so-called ceramic powder is a collection system of a large number of solid particles, it represents a state of existence of the material. The particle size of the solid particles composing the powder has a great influence on the properties of the powder system, especially when the particle size of the powder reaches the nanometer level, the specific surface area greatly increases, resulting in a rapid increase in surface energy and sintering activity. Greatly improved, these changes will bring about abrupt changes in the preparation of ceramic materials and the final material properties, thereby broadening the wider use of ceramic materials. How the nanopowders are characterized, conventional test methods are no longer applicable, and new test methods must be explored to obtain the desired characterization results.
In the production of building sanitary ceramics, the raw materials of clay, quartz and long quartz all need to be processed into powder particles. Both the dry pressed powder and the grouting slurry have particles. The ceramic colored glaze also has powder particles. The size of the particles directly affects the performance of the product. The particle size of the ceramic powder is an important indicator. The particle size and distribution are related to the processing time of the raw material, the density of the green body, the level of the firing temperature, etc., and play an important role in the quality and performance of the product. Therefore, particle size testing is very important in the processing and application of various types of powders. In the production of inorganic material products, the particle size distribution of the raw materials has a greater influence on the strength and process performance of the products. The general control of the raw material particle ratio should start from monitoring the particle size of the raw material.
Zibo Siyuan Ceramics New Material Co., Ltd. is a comprehensive company specialized in the production and research of forging machinery, fine ceramics and composite refractory products . It has a research and development system composed of senior professional technicians from various industries and well-known domestic institutions. Widely used in building ceramics factory, oil refinery, chemical plants, oil production plants, mining plants, power plants and other industries.
In the production of ceramic materials, fine grinding powders are usually used to shape the products by different methods. The changes that result in the production of finished products, especially when they are sintered, depend in many ways on the properties of the initial powder . First of all, it has a lot to do with its granularity. The well-known particle size determination methods include: sieve analysis, material layer permeability measurement, microscope measurement, and pulse method. One of the most promising tool is the laser method. When the average particle size is the same, the particle size composition (ie, particle size distribution) of the agglomerates is also substantially the same. Which Jinan Winner Particle Instruments Co., Ltd. R & D laser particle size analyzer reputation in the ceramic industry, its performance and quality by the ceramic industry customers alike. The average particle size obtained by laser granulometry can be used as a measure of the particle size of the milled ceramic powder. Based on this value, the process characteristics and product properties can be determined .
