Process and device for producing ultrathin vitrified tile

Abstract

The invention discloses a process for producing an ultrathin vitrified tile, which comprises the following steps of: 1, dry-mixing raw materials, and then adding water for carrying out wet mixing; 2, sending to an ageing tower for ageing after the wet mixing is finished; extruding the aged raw materials and a pigment through an extruding machine; 4, carrying out multiple times of step rolling on the extruded blank materials by using a multi-stage rolling manner to ensure that the blank materials reach the required thickness; 5, cutting the rolled blank materials to prepare a brick blank; 6, sending the brick blank to a drying kiln for drying; and 7, glazing and sintering the brick blank after drying. The invention has the advantages of being capable of realizing batch production of ultrathin brick blanks with very high strength and flatness by adopting an extruding-rolling manufacture method, laying the foundation of subsequent drying and sintering, avoiding generating defects of cracked and rugged bricks during drying and sintering, and improving the yield rate and the production efficiency of the ultrathin vitrified tile.

Description

Technical field: [0001] The invention relates to a production process and equipment for ultra-thin vitrified ceramic tiles. Background technique: [0002] The ceramic industry is a traditional industry with high energy consumption; low-carbon economy, energy saving and emission reduction are an eternal topic in the ceramic industry. In recent years, the country has vigorously advocated energy conservation and emission reduction, and ceramic enterprises have invested a lot of manpower and material resources to achieve good results. Ultra-thin vitrified tiles came into being in this environment. [0003] The thickness of traditional vitrified tiles is generally between 13 and 15mm, and the thickness of the ultra-thin vitrified tiles mentioned here is only 4-6mm. Then we roughly calculate the vitrified tiles with the same area, and the ultra-thin vitrified tiles only have traditional vitrified tiles. 40% of the weight of the tiles, that is to say, the raw materials used are o...

Problems solved by technology

The traditional production method of ultra-thin vitrified ceramic tiles is to adopt the pressing method, which is to use the stamping cooperation of the upper and lower molds to press the ceramic material in the mold cavity into adobe. However, because the thickness of the adobe is very thin, the thickness of the ultra-thin vitrified tile is only 4 ~ 6mm, using the above-mentioned traditional pressing method to manufacture ultra-thin vitrified tiles, the scrap rate and cost are quite high, which is not suitable for mass production line production, and when drying such thin bricks, the ultra-thin bricks are very sensitive to temperature , the deformation of the adobe is required to be extremely small and the flatness is very good. The adobe produced by the traditional method does not meet the requirements, resulting in deformation and breakage during drying. In the sintering stage, the ultra-thin adobe, especially the one with a length and width of more than 1 meter For large-scale products, if the quality of the adobe is not good, the adobe will often be prone to cracks or uneven defects during the sintering process.

Due to the above-mentioned end problems in the production of ultra-thin vitrified tiles, ultra-thin vitrified tiles have not been popularized all the time
