Laboratory trial firing process for determining mix proportion of ceramic particle raw materials

Abstract

The invention discloses a laboratory trial firing process for determining the mix proportion of ceramic particle raw materials. Ceramic particle raw materials whose chemical components have been known are accurately prepared through an electronic scale, manually, sufficiently and uniformly mixed, added with water to be blended and then uniformly mixed, so that the water content of the materials reaches 20%, and ceramic particle bodies, each of which has particle size ranging from 9.5 mm to 10.5 mm and weighs 2.9 g-3.1 g, are manually prepared for standby application; the ceramic particle bodies are dried at the temperature of 105 DEG C to reach a constant weight; the dried ceramic particle bodies are rapidly transferred to a box type high-temperature resistance furnace with the temperature of 400 DEG C to be preheated for 4 minutes; the dried ceramic particle bodies are rapidly transferred to a second box type high-temperature resistance furnace and subjected to high-temperature sintering expansion for 6 minutes; sintering expansion is tested through heating at the temperature rise amplitude of 30 DEG C until higher vulcanization and adhesion happen to ceramic particles at certain temperature, and the optimum sintering expansion range, the optimum sintering expansion temperature bandwidth and the optimum ceramic particle sintering expansion ratio are found out.

Description

technical field [0001] The invention relates to a process flow, in particular to a laboratory trial firing process for the mixing ratio of ceramsite raw materials. Background technique [0002] Ceramsite, as the name suggests, is ceramic particles. Most of the appearance characteristics of ceramsite are round or elliptical spheres, but there are also some gravel-like ceramsites that are not round or elliptical spheres, but irregular gravel. The shape of ceramsite varies from process to process. Its surface is a hard shell, which is pottery or enamel, which has the function of water-proof and air-retaining, and gives ceramsite high strength. Because there are many raw materials for the production of ceramsite, there are many varieties of ceramsite. At present, the application of ceramsite covers construction, landscaping, water treatment and other fields, and it is a new type of building material product promoted by the state. The different mixing ratios of ceramsite raw ...
