Technical Field

The invention relates to the technical field of ceramic processes, in particular to a sound absorption and noise reduction ceramic processing process.

Background

By "ceramic" is meant clay formed into a shape which, after drying, is heated to a certain degree to harden it and is no longer soluble in water. When and to what people the ceramics were invented, it is not known at all. However, it is certain that the invention of the ceramic must be after the person knows to use the fire. It was not surprising to find that the clay after firing became a solid shape which was very hard and no longer soluble, so that it was understood that pottery was made, and thus human life was not understood to be associated with the pottery.

Humans initially only know to fire ceramics at low temperatures and later slowly learn to fire ceramics at high temperatures. "pottery" is used broadly to refer to all ceramics, i.e., all clay or clay mixtures formed and fired into various articles. "porcelain" refers to a product fired at a relatively high temperature. The customary division method means that the green body contains high iron oxide and is dark red, and the green body is made of pottery when the firing temperature is below 1250 ℃. The green body contains less ferric oxide and is white, and the ceramic is obtained when the firing temperature is above 1250 ℃. And people can distinguish according to knocking sound, blank water absorption, light transmittance and the like. However, in practice, ceramics and porcelain are difficult to be clearly divided.

The manufacture of Chinese ceramics has already started from the age of Xinshi pottery eight thousand years ago. Although the invention of porcelain is late, the appearance of the porcelain is undoubtedly the result of great success obtained after the people accumulate abundant pottery making experience. The Chinese nation has no explanation that the Chinese nation is a nation with intelligence and creativity. The invention of porcelain enjoys a great position in the world, and a special title of China (China) is brought.

With the continuous development of modern civilization, the fashion of antiquing ceramics is popular, the luxurious, elegant and exquisite ceramics are more and more favored by consumers, and the ceramics are an indispensable appliance for human beings to maintain normal life, engage in production practice and develop social activities. At present, most ceramics do not have the functions of sound absorption and noise reduction, so a sound absorption and noise reduction ceramic processing technology is provided, and the ceramic processing technology is more suitable for consumption selection of people in daily life.
