Production process suitable for large-size earthenware pipe product

Abstract

The invention relates to a production process suitable for a large-size pottery pipe (also known as a pottery rod) product. The production process is specially developed for the large-size pottery pipe product of a specific structure. By adopting the production process provided by the invention to produce the large-size earthenware pipe product with the specific structure, the bending stress and deformation deflection of the unit section of the earthenware pipe product can be greatly reduced. According to the technology, the technical bottleneck that a large-size earthenware pipe product deforms due to the self-weight effect is solved, and only the peripheral parts shrink in the technological process of drying and sintering the earthenware pipe, so that the shrinkage is uniform, an earthenware pipe product with a flatter surface can be obtained, and the earthenware pipe has a relatively high yield.

Description

technical field [0001] The invention relates to a production process suitable for large-scale pottery pipe products, belonging to the technical field of building curtain walls. Background technique [0002] The curtain wall is the outer wall enclosure of the building. It is not load-bearing and hangs up like a curtain, so it is also called "curtain wall". It is a light-weight wall with decorative effect commonly used in modern large-scale and high-rise buildings. [0003] Regarding the materials used in the curtain wall, among them, pottery pipe (also known as pottery stick) is a new type of external decoration material introduced from abroad in recent years. It is mainly made of natural clay, shale and other raw materials through grinding, extrusion and high-temperature firing. made. Ceramic tubes have the advantages of beautiful appearance, heat insulation, sound insulation, corrosion resistance, etc., and are pollution-free, green, light in weight, good in earthquake res...

AI Technical Summary

Problems solved by technology

However, during the drying and firing process of the existing multi-cavity pottery tube, on the one hand, due to the different shrinkage rates of different cavity parts, the shrinkage is uneven, resulting in depressions or protrusions at the ribs, and uneven surfaces; On the other hand, the multi-cavity structure leads to poor circulation of hot air, rapid shrinkage of the surface, and slow shrinkage of the inner wall of the cavity, resulting in uneven stress. When the stress exceeds the strength of the green body, cracks or even cracks will appear in the green body; in addition, a single cavity The space of the body is small, and only small-sized fittings (fixed connection fittings) suitable for the size of the cavity can be used, but the weight per unit volume of the ceramic pipe is large, resulting in a low safety factor after installation
