Embodiment 1

[0072] A kind of adobe production method of dry pulverization, comprises steps (1)~(5), specifically as follows:

[0073] (1) The powder produced by the dry method is pressed into an adobe, and the adobe is a green adobe, and the adobe strength is 3Mpa. The moisture content of the adobe is 9%. The formula of the adobe contains 30% bentonite, the maximum pressure for pressing the adobe is 320Mpa, and the strength of the adobe after pressing can reach 3Mpa. The density of the adobe is 1.810g / cm 3 .

[0074] (2) The adobe is baked with a high-temperature lamp, and then the adobe is thrown and cut by an abrasive belt throwing machine with a thickness of 0.3 mm. Specifically, the adobe is transported to the bottom of the abrasive belt through the conveying mechanism, and the high-temperature lamp is set on the side of the conveying mechanism. The baking temperature of the high-temperature lamp is 105.3-110.7°C, and the baking time is 7 minutes. The edge of the adobe is closest t...

Embodiment 2

[0083] The brick adobe production method of the dry process pulverization of the present embodiment and the method for producing glazed ceramic tile are basically the same as embodiment 1, the difference is:

[0084] In step (1), the adobe strength is 4Mpa, and the moisture content of the adobe is 5%, and 45% bentonite is added in the formula of the adobe, and the maximum pressure of pressing the adobe is 300Mpa, so that the strength of the adobe reaches 4Mpa, and the compactness of the adobe 1.923g / cm 3 ;

[0085] In step (2), the throwing thickness is 0.1 mm, the baking time is 5 minutes, and the mesh numbers of the three sets of abrasive belts of the abrasive belt throwing machine are 320 mesh, 400 mesh, and 600 mesh.

Embodiment 3

[0087] The brick adobe production method of the dry process pulverization of the present embodiment and the method for producing glazed ceramic tile are basically the same as embodiment 1, the difference is:

[0088] In step (1), the strength of the adobe is 3.5Mpa, and the moisture content of the adobe is 7%. In the process of humidifying and granulating the powder for preparing the adobe, an organic particle reinforcing agent is added in an amount of 0.15%, and the amount of the adobe is pressed. The maximum pressure is 300Mpa, and the density of the adobe is 1.815g / cm 3 ;

[0089] In step (2), the throwing thickness is 0.2 mm, the baking time of the high-temperature lamp is 6 minutes, and the mesh numbers of the three groups of abrasive belts are 400 mesh, 400 mesh, and 600 mesh.

Abstract

The invention discloses a method for producing green bricks by adopting a dry powder process. The method comprises the following steps that (1), powder materials are pressed into green bricks by adopting the dry powder process, the green bricks are green bodies, and the strength of the green bricks is 3-4 MPa; (2), abrasive belts are used for cast cutting of the green bricks, and the thickness ofcast cutting is 0.1-0.3 mm; (3), the green bricks after cast cutting is polished by using a soft material; (4), grinding wastes on the surfaces of the green bricks are removed; (5), the green bricks with smooth and flat surfaces are obtained. Correspondingly, the invention further discloses a method for producing glazed ceramic tiles using the green bricks produced by the green brick production method using the dry powder process. The strength of the green bodies of the green bricks is increased to 3-4 MPa, so that the green bricks have large strength to withstand the cast cutting force of theabrasive belts. The green bricks have smooth and flat surfaces after cast cutting and polishing, the influence of the green bricks on the glaze decorative effect is reduced, and the cost of high-requirement tiles is further reduced. Meanwhile, there is more application space for the dry powder process.

Description

technical field [0001] The invention relates to the technical field of ceramic tile production, in particular to a production method of brick adobe and glazed ceramic tile produced by dry method. Background technique [0002] Traditional ceramic raw materials need to go through the process of coarse crushing, medium crushing and fine crushing to make the particle size of ceramic powder meet the requirements. Jaw crushers are generally used for coarse crushing, roller crushers or Raymond mills are generally used for medium crushing, and intermittent ball mill wet crushing is generally used for fine crushing. [0003] There are two types of molding methods for ceramics: plastic molding and semi-dry pressing molding. Different blank preparation methods are selected according to different molding methods. [0004] The preparation of plastic molding blanks is divided into wet mud making and dry mud making. The wet mud making method is to make the powder made of mud after crushin...
