Problems solved by technology

[0006] The object of the present invention is to overcome the above-mentioned shortcoming, provide a kind of fine stoneware brick and its preparation method that are made of ceramic solid recyclate, on the basis of not making major changes to the existing fine stoneware brick production process, through the The formula composition, the formula composition of the bottom glaze, the formula composition of the top glaze, and the adjustment and optimization of the firing process have solved the problem of product deformation and explosion caused by excessive gas generated by high temperature in the production and application of ceramic solid recyclates. bubbles, and even affect the quality of the product's internal quality and appearance, as well as defects such as pinholes and glaze bubbles in glazed stoneware products caused by excessive gas. At the same time, this technology has strong universality and is easy to use in the industry. to promote

Abstract

The invention relates to a fine stoneware tile produced by a ceramic solid recovered material and a production method thereof. Based on no great changed generated on the current fine stoneware tile production technology, adjustment and optimization can be carried out on formula composition of a biscuit, formula composition of a ground glaze, formula composition of cover glaze, and sintering, so that the ceramic solid recovered material is added in the biscuit formula to produce the fine stoneware tile product with excellent performance, the surface of the product presents a matte state, the product has the advantages of good flatness, high intensity, and high abrasion resistance, the glaze surface of the product has the advantages of smoothness and softness, no pin hole, and no glaze bubble, surface moulding and pattern design are closely matched, so that the fine stoneware tile has stone-like, wood-like, and cement brick-like effects; at the same time, the method has strong universality, and is easily popularized in industry.

Description

[0001] Technical field: [0002] The invention relates to the technical field of preparation of fine stoneware bricks, in particular to a fine stoneware brick made from recovered ceramic solids and a preparation method thereof. [0003] Background technique: [0004] With the rapid development of the ceramic industry, the solid recyclables produced in the ceramic production process, namely industrial waste, are increasing. According to incomplete statistics, the annual discharge of ceramic solid recyclables in my country is estimated to be more than 10 million tons. So far, in Although great progress has been made in the recycling of ceramic solid recyclables, individual enterprises can recycle ceramic solid recyclables in the production of small-sized exterior wall tiles and ceramic glazed tiles with a water absorption rate greater than 10%. There are few reports on the recycling of ceramic solid recyclates in ceramic tile products with low water absorption rate. This is mainly ...
