Problems solved by technology

The tin bath bottom brick produced with the above raw materials has the following defects: (1) The raw clay has a large shrinkage after drying and firing, and it is easy to form through capillary pores between the aggregate and the matrix, thereby reducing the tin bath bottom brick. (2) The main mineral composition of raw clay is kaolin or montmorillonite, which is transformed into mullite after burning:
[0005] Mullite is accompanied by large volume expansion in the process of transforming into nepheline, which can easily cause the upper surface of the tin bath bottom brick to peel off, thus affecting the service life of the tin bath bottom brick

Abstract

A bottom brick for tin pool used for the float glass production line is prepared from Si-Al clinker, low-Al fine powder, silicon brick powder, fine silicon powder, high-Al cement as binder, water reducing agent and water. Its advantage is long service life.

Description

technical field [0001] The invention relates to a tin bath bottom brick used for tin bath masonry in a float glass production line. Background technique [0002] At present, most of the methods for producing tin bath bottom bricks use sintered coke gemstones as aggregates and raw clay as binder. The tin bath bottom brick produced with the above raw materials has the following defects: (1) The raw clay has a large shrinkage after drying and firing, and it is easy to form through capillary pores between the aggregate and the matrix, thereby reducing the tin bath bottom brick. (2) The main mineral composition of raw clay is kaolin or montmorillonite, which is transformed into mullite after burning: <chemistry num="001"> <chem file="02139024_cml001.xml" / > < / chemistry> <chemistry num="002"> <chem file="02139024_cml002.xml" / > < / chemistry> <chemistry num="003"> <chem file="02139024_cml003.xml" / > < / chemistry> <che...
