Problems solved by technology

However, when the content of sand and alumina in the smoked brick raw materials increases, the middle of the brick is not cooked, and the quality of the finished product is poor; the melting temperature range of the potassium sodium feldspar flux is narrow, the process control is difficult, and the quality of the finished product is still low

preparation example Construction

[0033] A method for preparing high-quality smoked bricks, including steps (1) to (3), are specifically as follows.

[0034] (1) Weigh the raw materials of the smoked brick according to the proportion, then add water and knead evenly to make mud material, the amount of water added is 17-20% of the weight of the mud material.

[0035] (2) Aging the mud material for 24 to 48 hours, and then making mud granules by a screen granulator, extruding the mud granules through a vacuum extruder and cutting them into adobes.

[0036] (3) Dry the bricks and load them on the kiln car, and then enter the tunnel kiln to be fired into finished products at a firing temperature of 1055-1075°C.

Embodiment 1

[0038] The preparation method of embodiment 1 high-quality smoked brick is as follows:

[0039] (1) The raw materials of smoked bricks are 50% of plastic mud, 20% of clinker particles, 15% of sandy raw materials, 5% of flux, 8% of green color and 2% of lithium feldspar in weight percentage. The flux is nepheline syenite with a particle size of 200 mesh. The particle size of the clinker particles is 30 mesh. The raw materials of the smoked bricks are weighed according to the proportion, and then mixed with water to make mud evenly, and the amount of water added is 17% of the weight of the mud.

[0040] (2) Aging the mud material for 24 hours, and then making mud granules by a screen granulator, extruding the mud granules through a vacuum extruder and cutting them into adobes.

[0041] (3) Dry the bricks and load them on the kiln car, then enter the tunnel kiln to be fired into finished products at a firing temperature of 1055°C.

Embodiment 2

[0042] The preparation method of embodiment 2 high-quality smoked brick is as follows:

[0043](1) The raw materials of the smoked brick are 60% of plastic mud, 15% of clinker particles, 10% of sandy raw materials, 10% of flux, 4.5% of green color and 0.5% of lithium feldspar in weight percentage. The flux is composed of 95% potassium feldspar and 5% anorthite in weight percentage, and the particle size is 300 mesh. The particle size of the clinker particles is 15 mesh. The raw materials of smoked bricks are weighed according to the proportion, and then mixed with water to make mud evenly, and the amount of water added is 20% of the weight of the mud;

[0044] (2) Aging the mud for 30 hours, then making mud granules by a screen granulator, extruding the mud granules through a vacuum extruder and cutting them into adobes;

[0045] (3) Dry the bricks and load them on the kiln car, then enter the tunnel kiln to be fired into finished products at a firing temperature of 1075°C. ...

Abstract

The invention discloses a high-quality smoked brick. The smoked brick is prepared from the following raw materials in percentage by weight: 50 to 60 percent of plastic pug, 10 to 20 percent of clinkerparticles, 10 to 15 percent of sandy raw materials, 5 to 10 percent of flux, 0 to 10 percent of body pigment and 0.5 to 2 percent of lithium feldspar. Correspondingly, the invention further disclosesa preparation method of the high-quality smoked brick. The method comprises the steps of mixing, aging, drying and burning. The smoked brick and the preparation method thereof disclosed by the invention have the advantages of easiness in controlling a burning process and high quality of smoked bricks.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a high-quality smoked brick and a preparation method thereof. Background technique [0002] The smoked brick is a reduction reaction that occurs during the firing process, showing a smoked effect on the brick surface, and realizing the decorative effect after paving. The raw materials of smoked bricks are plastic mud, clinker particles, sandy raw materials, fluxes and pigments. These raw materials are made into bricks and then fired into kilns to become finished smoked bricks. During the high-temperature firing process, part of the ingredients in the raw materials are melted, and the bricks are prone to collapse and deformation, and even the collapse of the whole vehicle may occur. [0003] In the prior art, the strength of the adobe is improved by increasing the sand content or alumina content in the smoked brick raw material, or the risk of the adobe collapse and de...
