Embodiment Construction

[0028] Table 1 is the formula composition of the green body of the present invention; Table 2 is the chemical composition of the green body of the present invention.

[0029] The present invention at first mixes 30% by weight of calcium silicate slag raw material and 70% other blanks, mixing material: water=1: 1, makes green body mud slurry, then burns by existing conventional production method, burns The forming temperature is 1150° C. to 1200° C., and it only needs to be polished.

[0030] The composition of calcium silicate slag mainly includes: SiO 2 : 37~40%; CaO: 38~41%; AL 2 o 3 : 0.5~0.9%; Fe 2 o 3 2 O2 O<0.5%; discretionary amount<4.0%.

[0031] The mud composition mainly includes: SiO 2 : 55~65%; AL 2 o 3 ≥21%; Fe 2 o 3 +TiO 2 2 O+Na 2 O<1.5%; discretionary reduction<11%.

[0032] The whiteness of the mud is ≥55°, the shrinkage is less than 5%, and the plasticity: the flexural strength is required to be greater than 42 N.

[0033] The composition of hig...

Abstract

The invention relates to a method for manufacturing a polishing brick by utilizing calcium silicate slag, belonging to the technical field of ceramic manufacture. The polishing brick comprises the following raw materials in percentage by weight: 5%-30% of calcium silicate slag, 10%-30% of pug, 30%-65% of high-temperature sands, 5%-10% of intermediate-temperate sands and 0%-5% of steatites. The calcium silicate slag as raw materials is used in a blank of the polishing brick, thereby the shortage crisis of raw mineral materials is weakened and the discharge of the calcium silicate slag is reduced and then an energy-saving type polishing brick product is produced; the production energy consumption of the polishing brick can be reduced and utilization efficiency of resources is enhanced because the firing temperature of a blank body is reduced through calcium silicate contained in the calcium silicate slag; the invention not only reduces the pollution, but also increases a new member for the polishing bricks; and in addition, the novel polishing brick prepared by using the method has various properties which all accord with or surpass the national standard.

Description

technical field [0001] The invention relates to a method for manufacturing polished tiles by using calcium silicate, and belongs to the technical field of ceramic manufacturing. Background technique [0002] There are a wide range of raw materials for making ceramics, but with the dwindling of natural resources, especially the reduction of high-quality raw materials, the production of ceramics is limited. At home and abroad, attention has been turned to the use of industrial waste to manufacture ceramics. However, at present, waste ceramics generally have unfavorable factors such as complex components and difficult product quality control, which limits its development. As we all know, my country is a big country producing ceramics in the world, and the output of architectural ceramics has ranked first in the world since 1998. With the depletion of high-quality ceramic resources, it is imminent to seek recyclable raw materials. Calcium silicate slag is an intermediate produ...
