Embodiment 1

[0142] A new process for industrial mass production of foamed ceramics, comprising the following steps: the crushed (broken and ground) raw materials are sequentially smelted, extruded, dried and fired to obtain the foamed ceramics;

[0143] Raw materials include: 59% of the main raw material, 35% of the plastic regulator and 6% of the admixture; the main raw material is mineral processing tailings, the plastic regulator is 25% of kaolin and 10% of cellulose, and the admixture includes 3% of the foaming agent and the regulator 3%;

[0144] Note: The above percentages refer to the percentage of the raw material in the total mass of raw materials;

[0145] Foamed ceramics include the following components in mass percentage: K 2 O and Na 2 O total 18%, Al 2 o 3 35%, SiO 2 45%, CaO and MgO total 8% and Fe 2 o 3 4%;

[0146] The plasticity index of the mud obtained after mud refining is 6, the molding pressure is 17MPa, the vacuum degree during molding is 0.05MPa, and the ...

Abstract

The invention relates to the technical field of foamed ceramic production, and particularly provides a new process for industrial mass production of foamed ceramic, the foamed ceramic, application ofthe foamed ceramic and a building component. The new process for industrial mass production of the foamed ceramic comprises the following steps: sequentially crushing, grinding, pugging, performing extrusion molding, drying and sintering raw materials to obtain the foamed ceramic. According to the process, pugging and extrusion molding are adopted to replace the traditional wet ball milling and spray drying powdering process; the energy consumption required for drying, dehydrating and pulverizing is saved, a powder distribution system is not needed, kiln furniture such as a refractory surrounding edge, a silicon carbide bracket and refractory cotton of a kiln metering and batching furnace is omitted, and the gas energy consumption of the kiln is greatly reduced, so that the process is short in firing period and low in energy cost and equipment cost. Besides, the green body obtained by adopting the process is high in regularity, and components can be produced as required by adjusting the shape of an extrusion port, so that the cutting and grinding loss in the subsequent processing process is small, the waste of the raw materials is effectively avoided, and the yield is increased.

Description

technical field [0001] The invention relates to the field of foamed ceramics, in particular to a new industrial mass production process of foamed ceramics, foamed ceramics and its application, and building components. Background technique [0002] At present, my country is vigorously developing steel structures and prefabricated buildings to improve the standards and quality of construction projects. my country is actively promoting the construction of new urbanization, and there is a huge demand for new building energy-saving building materials. At the same time, my country has enforced energy conservation in public buildings, requiring the use of a large amount of wall insulation materials. Organic flammable wall insulation materials have not only caused many serious fire accidents, but also have problems such as large consumption, high energy consumption, and serious pollution. Can no longer meet the needs of the market. [0003] The whole body of foamed ceramics is made...
