Some common sense of special ceramics
Ceramics are widely used in people's daily life, but in the past, it was unimaginable that ceramics gradually replaced some precision equipment as a part. Nowadays, with the development of science and technology, special ceramics play an irreplaceable role in various industries due to their superior performance. At the high-performance ceramics exhibitions in Japan, Germany and other developed countries, the charm of special ceramics can be seen everywhere, and a piece of sophisticated and huge instruments and equipment bloom in this port.
The forming of special ceramics is to make ceramic raw materials into green bodies with specified shape, size and certain strength according to the requirements of actual production. The molding process depends on the nature of the ceramic raw material and the molding process. There are many ways to create the shape of ceramic products, but in general it can be divided into dry forming and wet forming.
Dry forming includes dry pressing, isostatic pressing, ultra-high pressure forming, powder electromagnetic forming, etc. Wet molding includes extrusion molding, injection molding, calendering film molding (calendering), slip casting, injection molding, tape casting, direct curing molding, colloid vibration injection molding, etc.
At present, the level of domestic special ceramics is limited to some small and precise parts, and some large-scale equipment and instruments still lack the mastery of their molding technology. However, with the wide application of special ceramics in the fields of electronics, medicine, food and military chemicals, special ceramics are playing an increasingly important role in China's development. Such as ceramic bearings on aircraft, warship decks, etc. The development of new materials such as China's special ceramics is also quite rapid.
At present, my country's functional ceramics account for 80% of the total sales of special ceramics, and it is growing at a rate of 20% every year. Among functional ceramics, electromagnetic functional ceramics account for 80%. That is, more than 60% of the special ceramics market is electromagnetic functional ceramics. Functional ceramics have been widely used in energy development, space technology, electronic technology, sensor technology, laser technology, optoelectronic technology, infrared technology, biotechnology, environmental science and other fields.
From the perspective of demand, key projects including large aircraft, high-speed rail, and new energy vehicles, as well as important industries such as triple play, Internet of Things, energy conservation and environmental protection, all need to apply various new materials, and their market demand continues to expand. New material products The import and export volume is also increasing year by year. In terms of policies, various special plans and policies are used to support the development of the new material industry. The number of projects and investment in the material field account for 15%-30% of the total science and technology plan. With the increase of market demand and the support of policies, emerging industries will give priority to the development of new materials.
The above are some knowledge points about special ceramics . I hope you can study and understand the relevant knowledge carefully, and choose products and equipment that suit your needs.
