Problems solved by technology

During the preparation process of the above-mentioned fired bricks, the clay was first pretreated with a fungicide, but the cinder was not pretreated, resulting in: 1. The whiteness of the fired brick product was low; 2. The flexural strength of the fired brick product was low, The average value is ≧2.26 Mpa, and the minimum value of a single block is ≧1.28Mpa; 3. The process of mixing clay, sludge and cinder consumes a lot of electricity and costs a lot
In addition, the amount of cinder used is less, only accounting for 5-10 parts by weight, and the recycling rate of cinder is not high

Abstract

The invention discloses a porcelain tile prepared from 15-25% of clay, 15-70% of coal cinder, 10-55% of feldspar and 2-10% of additives according to a formula, wherein the coal cinder is pretreated through the following steps of (1) sieving the raw material of the coal cinder; (2) recovering iron in the coal cinder through magnetic separation equipment; (3) adding water into the coal cinder, and carrying out ball milling treatment on the coal cinder to obtain a first mixed material; (4) adding water into the coal cinder, and recovering iron powder through iron removal equipment to obtain a second mixed material; (5) adding a bleaching agent into the coal cinder, and carrying out sedimentation and bleaching treatment through a sedimentation tank; (6) carrying out filter pressing treatment on the coal cinder; and (7) drying the coal cinder to obtain coal cinder containing less than 0.5% of TiO2, less than 0.05% of V2O5 and less than 0.5% of Fe. By using the porcelain tile, the ball milling efficiency is increased, the iron removal effect is improved, the whiteness of a product is greatly improved, and the removed harmful substances can be recovered.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a porcelain tile. Background technique [0002] my country's construction industry has a huge demand for porcelain tiles. Most of the conventional porcelain tiles need sandy barren raw materials. The formula is: clay 15-25%, feldspar 60-70%, additives 3-10%. Feldspar is a kind of barren sand material. The barren sand material is obtained from the mountains. It needs to strip off the surface vegetation and the sticky loess on the surface of the mountain. It has a great impact on the environment, destroys the national forest, and causes soil erosion at the same time. [0003] On the other hand, the output of industrial cinder is very large. Although there are some ways of environmental protection and reuse, such as: adding to processed cement, making municipal bricks, etc., the amount of addition and use is small, which is far from being able to digest the amount of cind...
