Abstract

The invention discloses a multi-phase toughened ceramic brick with the function of adjusting humidity and a production method thereof. The ceramic brick is divided into a fabric layer and a bottom material layer from top to bottom, and the fabric layer is composed of high-burning-lost-plastic soil and diatom pages. rock, vermiculite, bauxite, attapulgite, and micron alumina whiskers; the bottom material is composed of ceramic powder low-temperature powder whose firing shrinkage coefficient is basically the same as that of the fabric. After molding, it is fired at low temperature and the fabric layer The glass phase is not formed, the pores are not blocked, and due to the mismatch of expansion coefficients between various raw materials, small micro-cracks are generated on the submicron moisture absorption holes, which enhances the moisture absorption and desorption capacity of the product; the strength of the brick is guaranteed after the primer layer is sintered. The method disclosed by the invention solves the problem of low strength of the ceramic tiles of the existing humidity control materials.

Description

technical field [0001] The invention belongs to the field of preparation of architectural ceramic products, and in particular relates to a multiphase ceramic toughened ceramic brick with the function of regulating humidity and a production method thereof. Background technique [0002] The relative humidity of the air is a physical quantity indicating the amount of water vapor in the air, that is, the degree of dryness and humidity. It is an important parameter to measure the indoor environment. It is of great significance to human health, indoor air quality and the storage of items. Humidity affects human health, and has serious hazards to the preservation of items, the life of instruments, etc.; the harm is more serious when the humidity changes alternately from too high (low) to too low (high). The national "Air Quality Standard" stipulates the standard value of indoor relative humidity, which is 40% to 60% for air-conditioned rooms in summer and 30% to 60% for heated room...
