Ceramic wall-floor brick

Abstract

A ceramic wall and floor tile, characterized in that: the green body of the wall and floor tile is mainly made of the following raw materials in the weight ratio: 15-25 parts of silica sand, 45-60 parts of clay, 8-12 parts of limestone, and has low temperature Ceramic raw materials with fast burning properties: 15-20 parts of pyrophyllite and / or wollastonite and / or diopside and / or tremolite. The present invention introduces free SiO in the blank of ceramic wall and floor tiles 2 -Silica sand, so that river sand, beach sand, desert sand, etc. can be utilized, not only can save resources, protect the environment, and turn waste into treasure, but also due to the proper proportion of other blanks, the products produced have no cracking phenomenon and inherent quality Excellent, its performance index can reach: the shrinkage rate of the product is 0.5-0.8%, the water absorption rate of the product is 15-16%, the flexural strength of the product is 23-25MPa, and the product cost is reduced by more than 20%.

Description

Technical field [0001] The invention is a ceramic wall and floor tile. Background technique [0002] The existing ceramic wall and floor tiles mostly use feldspar, weathered feldspar, high-temperature sand, low-temperature sand, shale, white mud, black mud, etc. as the main raw materials to produce white or red bricks. This practice has a great impact on the environment and vegetation. The damage is serious, as is the massive consumption of white clay and white clay, which makes its resources increasingly depleted. Therefore, relevant national policies advocate the use of white clay as little as possible. Silica sand is a kind of raw material that exists in large quantities in rivers and deserts. The large amount of silica sand deposited in rivers can block the river and cause flooding. The silica sand in the desert is the source of sandstorm disasters. If it can be taken and used, Replacing soil can turn waste into treasure and protect vegetation. However, there is a misundersta...

Problems solved by technology

[0002] Most of the existing ceramic wall and floor tiles use feldspar, weathered feldspar, high-temperature sand, low-temperature sand, shale, white mud, black mud, etc. as the main raw materials to produce white or red bricks. This method is harmful to the environment and vegetation. The damage is serious, and the large consumption of white clay and white clay makes its resources increasingly exhausted. Therefore, the relevant national policies advocate the use of white clay as little as possible.

Silica sand is a raw material that exists in large quantities in rivers and deserts. A large amount of silica sand deposited in rivers can block river courses and cause floods. Silica sand in deserts is the source of sandstorm disasters. If it can be used, Instead of soil, it can turn waste into treasure and protect vegetation, but there is a misunderstanding in the traditional concept of the ceramic industry: it is believed that the raw material of ceramic wall and floor tiles can only use SiO in a combined state. 2 , can not introduce free SiO 2 (Silica sand belongs to free SiO 2 ), otherwise when fast burning in roller kiln, SiO 2 When the crystal is turned, it will cause the product to crack
