A method of firing light-weight porcelain plates for exterior wall decoration by using a roller kiln

Abstract

The invention discloses a method for firing a light-weight porcelain plate for exterior wall decoration by utilizing a roller kiln, which belongs to the technical field of building ceramic production. It is characterized in that it comprises the following steps: adding water to kaolin, feldspar, quartz, dolomite, sillimanite, raw coke, barium carbonate, magnesium oxide, pyrophyllite and barium sulfate, ball milling, drying and making pellets, and then After pressing and glazing, it is fired in a roller kiln at 1170°C with a firing cycle of 50 minutes to produce lightweight porcelain plates for exterior wall decoration. The density of the lightweight porcelain plate for exterior wall decoration obtained by the method is slightly lower than that of traditional ceramics, the pores are closed, the water absorption rate is low, and the impact resistance is strong, which can meet the climate test, construction and application in the field of exterior wall space decoration. Basic requirements for decoration.

Description

technical field [0001] The invention discloses a method for firing a light-weight porcelain plate for exterior wall decoration by utilizing a roller kiln, which belongs to the technical field of building ceramic production. Background technique [0002] In recent years, with the rapid and healthy development of the global economy, the level of urbanization is getting higher and higher, and the urbanization process is also getting faster and faster. It is estimated that by 2030, 60% of the world's people will live in cities. As an important part of the city's external space, the city square and the facade of the main building are a sign of the degree of civilization of the city's economy, culture and ideology. People's requirements for decorative materials for building exterior walls are becoming higher and higher, glass curtain wall materials are limited due to light pollution problems, and natural stone materials are also becoming scarce due to the increasing scarcity of re...

Problems solved by technology

[0003] In the practical application of ceramic boards for dry-hanging decoration, the following difficulties need to be overcome: (1) There must be an appropriate amount of pores inside the boards. On the one hand, the weight and thermal conductivity can be reduced; The board has a certain machinability, that is, it can ensure that brittle fracture will not occur when the back of the ceramic board is processed and drilled; (2) Avoid the connectivity of internal pores to ensure the weather resistance of the decorative board, because the connected holes It will cause problems such as increased water absorption, freeze-thaw cycles and weathering, which will greatly reduce the service life of the board

So far, there is no research report on the rapid firing of ceramic plates with closed pores, low water absorption and strong impact resistance through roller kiln
