Problems solved by technology

[0002] Ceramics have a long history of use in our country, and are now widely used all over the world. Daily-use ceramics have become an indispensable part of people's daily life. All kinds of tableware, tea sets, and various sanitary ware can be seen everywhere. These ceramics It is not only beautiful and generous, but also has the advantages of easy cleaning, temperature resistance, wear resistance and corrosion resistance, etc., and is deeply loved by consumers. However, ceramic products are generally brittle, not resistant to impact, poor toughness, uneven glaze color and easy to fall off. , high production energy consumption and other shortcomings, resulting in serious damage in the process of production, transportation and application, thereby increasing production costs. Therefore, it is urgent to improve its performance and promote the development of the daily-use ceramics industry in the direction of low cost and green environmental protection.

Abstract

The invention relates to a domestic ceramic product, and particularly relates to a domestic ceramic product containing nanometer aluminium oxide and a production technology thereof. The ceramic product is produced by adopting the following raw materials in parts by weight: 50-55 parts of natural clay, 12-14 parts of nanometer aluminium oxide, 2-3 parts of chromic oxide, 20-23 parts of sepiolite, 10-12 parts of aluminium silicate powder, 5-8 parts of titanium dioxide, 20-23 parts of nanometer fluorite powder, 15-20 parts of barium sulfate, 4-5 parts of polyvinyl alcohol and 5-6 parts of an additive. The strength and the toughness of the ceramic product are improved by using the unique characteristics of the nanometer raw materials such as the nanometer aluminium oxide and the nanometer fluorite powder; the nanometer materials are matched with the other raw materials, so that the prepared ceramic product has good whiteness and is uniform in color and luster and compact in glaze, the sintering temperature is effectively reduced, and the production energy consumption is controlled. Compared with a common ceramic product, the ceramic product produced by the technology has excellent performances and is high in application value; the production technology is relatively simple.

Description

technical field [0001] The invention relates to a daily-use ceramic product, in particular to a daily-use ceramic product containing nano-Al2O3 and a manufacturing process thereof. Background technique [0002] Ceramics have a long history of use in my country and are now widely used all over the world. Daily ceramics have become an indispensable part of people's daily life. All kinds of tableware, tea sets, and various sanitary ware can be seen everywhere. It is not only beautiful and diverse in shape, but also has the advantages of easy cleaning, temperature resistance, wear resistance and corrosion resistance, etc., and is deeply loved by consumers. However, ceramic products are generally brittle, impact-resistant, poor in toughness, and uneven in glaze color and easy to fall off. The disadvantages of high energy consumption, high energy consumption, etc., lead to serious damage during production, transportation and application, thereby increasing production costs. Therefor...
