Problems solved by technology

In the prior art, it is not specifically used for pointing in the construction of refractory materials, and only ordinary amorphous refractory materials can be used for pointing construction; ordinary amorphous refractory materials are made of refractory aggregates and binders. It is a kind of refractory material similar to cement. Ordinary unshaped refractory materials have a single aggregate particle size, and even if there are some powder materials, they are also some raw materials that are the same as or similar to the aggregate. During the pointing construction process, these Aggregate tends to agglomerate together, while powder often adheres to the surface of the aggregate to form larger particles or particle agglomerates. For commonly used unshaped refractory materials, these can be solved by means of vibration, etc., but for connection Due to the limitation of space and construction requirements, these processes cannot be used for the pointing treatment of joints. Therefore, a kind of refractory material that is not easy to agglomerate and adhere to the amorphous refractory during the construction process is required, and it should have good fluidity and can be used in the construction process. Flow in the link seam and be able to fill the joint seam completely

Abstract

The invention belongs to the technical field of refractory materials, and discloses an unshaped refractory material for jointing. The unshaped refractory material for jointing is prepared from the raw materials: coarse aggregates, fine aggregates, powder, paper pulp, crystalline graphite powder, talcum powder, plaster and the like, wherein the coarse aggregates are corundum coarse aggregates; the fine aggregates are quartz sand fine aggregates; the powder is mullite powder; the paper pulp is prepared from recycled paper pulp and sulfite wood pulp. According to the unshaped refractory material for jointing disclosed by the invention, a requirement of the refractory material on fire resistance can be met, and an influence on the overall performance of a kiln is little after construction; the unshaped refractory material for jointing has good flowability, and a connection joint among refractory material block bodies can be quickly and completely filled and leveled.

Description

technical field [0001] The invention relates to the technical field of refractory materials, in particular to an unshaped refractory material for pointing. Background technique [0002] In the traditional sense, refractory materials refer to inorganic non-metallic materials with a refractoriness of not less than 1580 °C. And parts of the material, and can withstand the corresponding physical and chemical changes and mechanical action. [0003] Most refractory materials are made of natural ores (such as refractory clay, silica, magnesite, dolomite), and some industrial raw materials and synthetic raw materials (such as industrial alumina, silicon carbide, synthetic mullite, Synthetic spinel, etc.) are also increasing, so there are many types of refractory materials. According to the mineral composition, refractories can be divided into silica, aluminum silicate, magnesia, dolomite, olivine, spinel, carbonaceous, zirconium-containing refractories and special refractories; ac...
