Problems solved by technology

[0005] In order to solve the ceramic railings pointed out in the background technology, due to its own factors, the glaze surface is prone to fall off during use, and cracks appear in some structures, especially in the climate conditions with large temperature differences, which will seriously affect the normal use, and during firing. During the process, the airflow in the kiln is uneven, the heat transfer is slow, and the heat exchange efficiency is low, which is not conducive to the formation of a regular and controllable temperature gradient in the longitudinal direction of the firing zone in the kiln, and the technical problems of prolonging the firing cycle. The purpose of this application is to Provide a highly weather-resistant ceramic railing and its preparation method. The ceramic railing is improved from the raw material formula, and the local porcelain clay resources in Yunnan are used as raw materials. The ceramic railing blank and glaze formula are further optimized, and at the same time, it is combined with the firing process Improvements are made in the process to improve the weather resistance of the final product. The performance indicators of ceramic railing products such as water absorption, frost resistance, rapid cooling and rapid heat resistance, and appearance quality are better than the "JC / T765-2006" architectural glass products standard

Abstract

The invention provides a ceramic railing with high weatherability, and a preparation method thereof. Because of self-factors, when a ceramic railing is used, glaze-surface falling and cracks on parts of the structures can easily occur; under weather conditions with large temperature differences, glaze-surface bursting might occur, and normal application is severely influenced; during a firing procedures, because of uneven air flow, slow heat transfer and low heat exchange efficiency in a kiln, regular and controllable temperature gradient can hardly be formed longitudinally in a firing zone in the kiln, such that the firing period is prolonged. With the method provided by the invention, the technical problem is solved. According to the invention, a raw material formula is modified, and a local clay resource in Yunnan Province is adopted as a raw material. The formulas for a ceramic railing blank and a glaze are further optimized, and a firing process procedure is also modified, such that the weatherability of a finished product is improved. Indexes of performances such as water absorption rate, freezing resistance, quick-chilling resistance, quick-heating resistance and appearancequality of the ceramic railing product satisfy a construction colored glaze product standard JC / T765-2006.

Description

technical field [0001] The invention relates to the field of ceramic production, in particular to a highly weather-resistant ceramic railing and a preparation method thereof. Background technique [0002] Weather resistance means that industrial and building materials are used outdoors to withstand the test of climate, such as comprehensive damage caused by light, cold and heat, wind and rain, bacteria, etc., and its tolerance is called weather resistance. [0003] Ceramic materials are compounds between metal and non-metal elements, mostly oxides, nitrides and carbides. Common ceramic materials are composed of clay minerals, cement, and glass. These materials are typical electrical and thermal insulators, and are more resistant to high temperatures and corrosive environments than metals and polymers. Therefore, in construction engineering, the factors that need to be considered when evaluating the weather resistance of ceramic materials are mainly the brittleness of cerami...
