Fly ash floating beads in thermal power plant, flotation of alumina-silica glass hollow balls. Average particle size, hardness type, spelling and thermal conductivity. Loose density It is light, thin and hollow, with smooth surface, high temperature resistance and good heat insulation. Using these characteristics of floating beads, light thermal insulation materials with excellent thermal insulation performance can be produced, and floating bead bricks can be produced by semi-dry method. This secondary molding method is simple, and its technological process does not need to complete plastic processing:
The floating bead brick produced by this wide floating bead is superior to the existing intermediate thermal insulation material in mechanical strength, high temperature resistance and thermal conductivity, and can be comparable to aluminum silicate fiber. There are 42 comprehensive energy utilization pools in the glass melting furnace of Xuanwei Glass Factory, which can comprehensively utilize heat energy in the water and air pipelines in the north, and the product quality reaches 38%, which is greatly improved. The qualified rate of glass products has been increased from 80% to 95%, and the quality of iron has also been greatly improved. Therefore, heat insulation materials are widely used in metallurgy, machinery, chemical industry, petroleum, building materials, electric power and other fields. It is an industrial furnace and high-temperature equipment, which generally saves energy 15% ~ 42. It is a new type of light heat insulation material.
