Embodiment 1

[0071] A method for producing grouted glazed tiles, comprising steps (1) to (5), specifically as follows:

[0072] (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. Apply mud glaze on the surface of the brick to form a mud glaze layer, and the amount of mud glaze applied is 665g / m 2 , the specific gravity of the slurry glaze is 1.55g / ml, and the slurry glaze is a mixed slurry of slurry and glaze. Slurry glaze is a mixed slurry made of mud and glaze plus water, wherein the weight ratio of glaze to mud is 87:13.

[0073] (2) After the mud glaze layer of the brick adobe is dried to a moisture content of 9%, the adobe is baked with a high-temperature lamp, and then the mud-glazed adobe is thrown a...

Embodiment 2

[0082] The method for producing the slurry glazed brick adobe of the present embodiment and the method for producing the glazed ceramic tile are basically the same as in Example 1, the difference is that:

[0083] In step (1), the brick brick strength is 4Mpa, the moisture content of brick brick is 5%, adds 45% bentonite in the formula of brick brick, the maximum pressure of pressing brick brick is 300Mpa, makes the intensity of brick brick reach 4Mpa, the applying of mud glaze The amount is 950g / m 2 . The specific gravity of the slurry glaze is 1.85g / ml, and the weight ratio of the glaze to the mud is 15:85.

[0084] In step (2), the mud glaze layer is dried to a moisture content of 5%, the throwing thickness is 0.1 mm, and the baking time is 5 minutes. After the baking is completed, the moisture content of the upper 1 / 3 thickness of the mud glazed brick is 4%. The mesh numbers of the three sets of abrasive belts of the abrasive belt throwing machine are 320 mesh, 400 mesh ...

Embodiment 3

[0086] The method for producing the slurry glazed brick adobe of the present embodiment and the method for producing the glazed ceramic tile are basically the same as in Example 1, the difference is that:

[0087] 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 applied amount of slurry glaze is 810g / m 2 . The specific gravity of the slurry glaze is 1.75g / ml, and the weight ratio of the glaze to the mud is 64:36.

[0088] In step (2), the mud glaze layer is dried to a moisture content of 7%, the throwing thickness is 0.15 mm, and the baking time of the high-temperature lamp is 6 minutes. After the baking is completed, the moisture content of the upper 1 / 3 thickness of the mud glaze brick is 3%. The me...

Abstract

The invention discloses a preparation method for a raw brick glazed with a slip glaze. The method comprises the following steps that (1) a powder material prepared by dry powdering is pressed into theraw brick, the raw brick is a green body, the strength of the green body is 3-4 MPa, the slip glaze is applied on the surface of the green body to form a slip glaze surface layer, and the applying amount of the slip glaze is 750-900 grams per square meter; (2) the raw brick with the slip glaze layer is dried until the moisture content is 5-9%, an abrasive belt is adopted to cast and cut the slipglaze layer, the casting cutting thickness is 0.05-0.15 millimeter; (3) a soft material is adopted to burnish the casted and cut raw brick; (4) burnishing waste on the surface of the raw brick is removed; and (5) the slip glaze raw brick with the flat surface is obtained. The invention further correspondingly discloses a method for preparing a glaze ceramic tile by using the raw brick prepared bythe above preparation method for the raw brick glazed with the slip glaze. The raw brick with the slip glaze layer is casted, cut and burnished to have the smooth flat surface, thereby improving the expressive force of the slip glaze raw brick on the upper-layer decorative glaze of the slip glaze raw brick, and further reducing the cost of the ceramic tile with high requirements.

Description

technical field [0001] The invention relates to the technical field of ceramic tile production, in particular to a method for producing slurry-glazed tile blanks and glazed tiles. 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] Preparation of plastic molding blanks: divided into wet mud making and dry mud making. The wet mud making method is to make mud powder after crushing and fine grinding. ;Dry mud mak...
