What are the shapes of ceramic?
Article source:
First, the shape of the classification of a gravel-shaped Ceramic: Ceramic generally use natural gravel-type ore production, the first stone grinding, roasting, then sifter; natural and artificial light can also be used raw materials such as pumice, scoria, cinder, coal gangue and other natural or calcined directly derived from crushing and screening. 2 cylindrical ceramic: ceramic suitable for such a high plasticity clay and other raw materials, production is relatively low. Cylindrical ceramic commonly used plastic extrusion. First made of clay, and then cut into a cylindrical shape. If using a cylindrical blank brick back firing in the kiln cylinder roll into an oval. 3 spherical ceramic: At present, China's market is such a variety of ceramic majority, is the use of spherical ceramic disc granulator production. First raw material mill, and then granulated with water, then the ball is made from calcined or conservation. Second, on the ceramic explanation about the internal structure of porous ceramic honeycomb showed a fine. These pores are closed, rather than the type of communication. It is to be wrapped into the gas formed by the shell, which is the main reason for lightweight ceramic. Many of the lightweight ceramic excellent performance is the most important thing is that it can replace the main reason for the heavy gravel. Because a lot of the production of ceramic materials, ceramic there are many varieties, so many colors it. Unburned solid waste ceramic used because different colors, usually gray and black, no gloss surface, as firing ceramic smooth. There are many fine particles of less than 5 mm in the ceramic, the screening machine used in the production of this part of screening out small particles, called pottery sand on habits. Part of the fine particles of ceramic pottery known as sand. Tao sand slightly higher density, good chemical and thermal stability. Pottery is mainly used to replace natural river sand or sand hill formulated lightweight aggregate concrete, light mortar, but also for acid, heat fine aggregate concrete. The main varieties of sandstone and shale clay pottery pottery pottery sand sand and fly ash. The purpose is also to reduce the pottery building sand weight. Tao sand can also be used in soilless cultivation and industrial filtration.
