Abstract

The invention relates to a wear-resistant heat preservation ceramic composite material which belongs to the field of materials and comprises primary materials and auxiliary materials according to weight percentage. The primary materials comprise corundum, chromic oxide, limestone, silicon dioxide, high alumina clay, silicate or calcium aluminate cement; the auxiliary materials comprise perlite powder, magnesia, quartz sand component, titanium oxide, dolomite, attapulgite, high temperature caking agent, composite strengthening agent, feldspar, and short carbon fiber component. The wear-resistant heat preservation ceramic composite material has the advantages of high intensity, being suitable for the strong eroding of various mediums, strong adhesive attraction, as well as excellent wear resistance and heat preservation performance. The wear-resistant heat preservation ceramic composite material has small coefficient of heat conduction, high melting point, and low linear expansibility. The integral performance is stable; the acid resistance, the alkali resistance and the erosion-proof capacity are strong; the density is small; a seamless integral wear-resistant heat preservation layer is formed after solidifying; the performance is extremely excellent; moreover, the wear-resistant heat preservation ceramic composite material is not easy to fall off, can effectively prolong the service lives of devices and pipelines, is convenient to be constructed, is used inside the pipelines, has the double effects of wear resistance and heat preservation, greatly reduces the production cost of enterprises, and improves the economic benefits thereof.

Description

1. Technical field [0001] The invention relates to a wear-resistant and heat-preserving ceramic composite material, which belongs to the field of materials. 2. Background technology [0002] At present, in cement, steel, thermal power, petrochemical metallurgy, mining coal and other heavy industries, there are a large number of high-temperature hot air pipelines, equipment and pipelines for washing dust materials. For example: pulverized coal transportation, combustion pipelines, tertiary air ducts in the cement industry, high-temperature air ducts and high-humidity air ducts, heat exchangers and humidification towers, and cement kiln shells, which are difficult to keep warm, and dew condensation in dust collectors and other equipment, due to The coal consumption of the dryer is high, the temperature difference of the calcination section in the kiln is large, the coal consumption is high, and the quality of the clinker is unstable.

Problems solved by technology

For example: pulverized coal transportation, combustion pipelines, tertiary air ducts in the cement industry, high-temperature air ducts and high-humidity air ducts, heat exchangers and humidification towers, and cement kiln shells, which are difficult to keep warm, and dew condensation in dust collectors and other equipment, due to High coal consumption in the dryer, large temperature difference in the calcined section in the kiln, high coal consumption, and unstable clinker quality

The internal materials of the above equipment and pipelines are severely eroded and worn, and the temperature difference between inside and outside is large. The outer walls of some equipment and pipelines have to be thickened with external insulation materials such as glass fiber or asbestos boards, which not only increases the production cost of the enterprise, but also pollutes the environment.

A large number of equipment or pipelines will be strongly scoured by various media during use. This kind of impact and wear in use will reduce the service life of equipment or pipelines, resulting in an increase in the frequency of equipment shutdown, disassembly, and external insulation maintenance, which will not only reduce equipment efficiency. , energy consumption increases, production costs rise, and the workload of maintenance workers will also increase
