Problems solved by technology

However, the composition of Longyan raw ore is very unstable, so most of the ceramics are made of washed mud after washing, and a large number of Longyan sand heads (the content fluctuates between 60-85%) are discarded, resulting in huge environmental pressure.

Abstract

The invention relates to daily high-silicon reinforced porcelain and a preparation method thereof, in particular to high-silicon daily reinforced porcelain prepared by taking Longyan sand head as a main raw material, and belongs to the field of daily reinforced porcelain. The porcelain body is mainly composed of the following components in percentage by mass: 40 to 70% of Longyan sand head, 0 to 10% of feldspar mineral, and 25 to 50% of clay mineral. According to the method, feldspar and quartz can be completely provided by the Longyan sand head, a large amount of high-quality feldspar and quartz resources are saved, waste sand head resources are fully utilized, and the method has huge social, economic and technical values.

Description

technical field [0001] The invention relates to a daily-use high-silicon strengthened porcelain and a preparation method thereof. Specifically, the high-silicon daily-use strengthened porcelain prepared by using Longyan sandstone as a main raw material belongs to the field of daily-use strengthened porcelain. Background technique [0002] Longyan kaolin in Fujian Province has a total proven raw ore reserve of nearly 80 million tons. The annual production capacity of kaolin raw ore is 600,000 tons. It can be mined for more than a hundred years. It has low content of harmful impurities such as iron and titanium, high firing whiteness, and good porcelain-forming performance. It is widely used in daily-use ceramics, arts and crafts ceramics and high-grade architectural ceramics. However, the composition of Longyan raw ore is very unstable, so most of the porcelain is made of washed mud after washing, and a large number of Longyan sand heads (the content fluctuates between 60-85%...
