Example Embodiment

[0031] Example 1

[0032] Follow the steps below to prepare dry-grain glazed tiles:

[0033] 1. After the bricks hit by the press are dried for the first time, control the drying temperature to 90℃ and time for 120min to remove the free water inside, so that the moisture of the bricks is less than 0.5%; spray water on the surface of the bricks after leaving the drying kiln. A water film is formed on the surface, and the amount of spray water mist is 120g / m 2 ;

[0034] 2. Then pour the base glaze on the surface of the body, the amount of glaze is 87g (340*670 tray); the base glaze includes SiO in mass percentage 2 40%, Al 2 O 3 15%, CaO10%, MgO8%, ZnO15%, K 2 O6%, Na 2 O3%, BaO3%; then use the inkjet machine to print the pattern, and then dry it in the second drying kiln. The drying temperature is controlled to 200℃ and the time is 20min;

[0035] 3. Spray dry granular glaze; dry granular glaze flow rate is 26s, specific gravity is 1.27g / ml, glaze volume is 67g (340*670 tray), finenes...

Abstract

The invention provides a method for preparing a matte dry granular glazed brick. The method comprises the following steps: carrying out first drying on a green brick made by a pressing machine, removing free water in the green brick, and controlling the water content in the green brick to be smaller than 0.5 percent of the total weight of the green brick; spraying water mist to the surface of thegreen brick after taking the green brick out of a dry kiln; then sprinkling ground glaze to the surface of the green body, then spraying and painting patterns by using an ink jet machine, and carryingout second drying through the dry kiln; spraying dry granular glaze, putting in a firing kiln after carrying out third drying of the dry kiln, and firing at a high temperature of 1170 to 1185 DEG C for 60 to 70 minutes, thus obtaining a semi-finished product; edging the semi-finished product, flexibly polishing the semi-finished product by using a fiber polishing module combination, and packaginginto a finished product after checking the quality. According to the method provided by the invention, the prepared matte dry granular glazed brick has a vivid stone texture, and meanwhile, the touchsense is mild as jade.

Description

technical field [0001] The invention relates to the field of ceramics, in particular to a method for preparing matte dry grain glazed tiles. Background technique [0002] In recent years, the market share of modern antique bricks is getting higher and higher, and the cultural elements such as the sense of history, nostalgia, nature, return, and individuality and the fashionable and popular styles revealed by it have gradually gained more and more attention. attention and recognition. Matte and soft dry grain glazed tiles are an upgraded product of modern antique tiles. It not only inherits the unique cultural elements of antique tiles and the super hardness of polished tiles, but also endows them with a more realistic stone texture, and at the same time feels warm and moist. Jade, without the cold feeling of stone. [0003] There are many such products on the market at present, just simply mix dry granules and suspending agent in a certain proportion, and spray evenly on t...
