Abstract

The invention discloses a process for producing foamed ceramic based on layered and sectionalized material preparation and distribution, and relates to the field of materials. According to the process, a plurality of foamed ceramic particles different in foaming agent content and particle size are used, and a foamed ceramic material is produced through layered and sectionalized material distribution. The process is characterized in that the particles on the lower layer have small particle sizes and high foaming agent content, while the particles on the upper layer have large particle sizes andlow foaming agent content, so that a channel is provided for low temperature exhaust, and the time for low temperature exhaust is shortened; the arrangement mode is also beneficial to heat transfer;the uneven foaming caused by the temperature gradient is compensated; the temperature rise rate in the foaming and firing stage is increased; the preserving time at the foaming temperature is shortened, and accordingly, the entire production cycle of the foamed ceramic material is shortened. The foamed ceramic material prepared by the process has high quality, few defects and a short production cycle, thereby being suitable for mass production.

Description

technical field [0001] The invention relates to the field of materials, in particular to a process for producing foamed ceramics by layering and subdividing materials and fabrics and foamed ceramic materials. Background technique [0002] At present, foamed ceramics usually use solid waste such as tailings, polishing slag, and pressed mud as the main raw materials, add feldspar, waste glass, talc, etc. Spherical pellets with a diameter of 40 to 60 meshes are prepared by granulation. Then the granular material is distributed into the grinding tool through the distributor, foamed and fired at high temperature, and the foamed ceramic material is obtained after cooling. [0003] Foamed ceramics are used as light-weight wall materials, and the product thickness requirements are generally 100-300mm. In order to prepare the foamed ceramic wall material with the thickness, the cloth thickness of the 40-60 mesh spherical granular material is 50-150 mm. Before the low temperature s...
