Embodiment 1

[0058] This embodiment provides a tempering paste for reducing the firing temperature of spotted bricks, wherein the raw materials of the tempering paste include:

[0059] Talc 48% to 52%; Magnesia 18% to 22%; Hui Na sand 28% to 32%.

[0060] It can be understood that in the tempering paste provided in the present invention, mud materials with good fluxing effect are used, so that the spotted bricks are affected by the added speckle particles, and after the firing temperature is increased, by adding the tempering paste , effectively reduce the firing temperature of spotted bricks, and then maintain the stability of the firing temperature of spotted bricks, improve the color repeatability between different batches of spotted bricks, ensure the continuity of production, and improve production efficiency; At the same time as the firing temperature of the bricks, the whiteness of the spotted bricks can not be affected, and the strength of the spotted bricks can be simultaneously i...

Embodiment 2

[0062] This embodiment provides a tempering paste for reducing the firing temperature of spotted bricks, which is different from the first embodiment above in that: the raw materials of the tempering paste are calculated by mass percentage, including:

[0063] Talc 50%; Magnesia 20%; Hui Na sand 30%.

[0064] It can be understood that in the tempering slurry provided in the present invention, mud materials with high aluminum content, low magnesium content and low iron content and good fluxing effect are used, so that the spotted bricks are affected by the added spotted particles, making them After the firing temperature is increased, the firing temperature of the speckled bricks can be effectively reduced by adding tempering paste, thereby maintaining the stability of the firing temperature of the speckled bricks, improving the color repeatability between different batches of speckled bricks, and ensuring The continuity of production improves production efficiency; while stabi...

Embodiment 3

[0066] This embodiment provides a kind of tempering paste that reduces the firing temperature of spotted bricks. The chemical composition of the tempering paste is calculated by mass percentage, including:

[0067] SiO 2 60.18%; Al 2 o 3 5.96%; Fe 2 o 3 0.40%; CaO 0.76%; MgO 22.36%; K 2 O0.24%; Na 2 O 2.65%; loss on ignition 7.45%.

Abstract

The invention discloses a temperature regulating slurry for reducing the firing temperature of a brindled brick, the brindled brick and a manufacturing method of the brindled brick. The temperature regulating slurry comprises the following raw materials in percentage by mass: 48%-52% of talc particles; 18%-22% of magnesia; and 28%-32% of sodium humate. A mud raw material with high aluminum content, low magnesium content, low iron content and good plasticity is adopted in the temperature regulating slurry, so that the brindled brick is influenced by the added brindle particles and the firing temperature of the brindled brick is increased, the firing temperature of the brindled brick is effectively reduced by adding the temperature regulating slurry, so that the stability of the firing temperature of the brindled brick is maintained, the quality and color repeatability among different batches of brindled bricks is improved, the production continuity is ensured, and the production efficiency is improved; and while the firing temperature of the brindled brick is stabilized, the whiteness of the brindled brick is not influenced, and the strength of the brindled brick can be synchronously improved.

Description

technical field [0001] The invention relates to the field of production of building ceramic spotted bricks, in particular to a tempering slurry for reducing the firing temperature of the spotted bricks, the spotted bricks and a manufacturing method thereof. Background technique [0002] With the development of the architectural ceramics industry, architectural ceramic decoration technology is no longer limited to brick surface pattern decoration, and speckled bricks (spotted ceramic tiles, speckled particles of various colors are added to the body) have begun to gradually occupy the trend. [0003] In the production process of the existing spotted bricks, it is necessary to add speckled particles of different colors to the basic slurry of the spotted bricks, and the added speckled particles will change the chemical composition content of the basic slurry, and then affect the firing temperature of the spotted bricks (blank temperature ), resulting in an increase in the firing...
