Description

The high-grade daily-use fine porcelain and the production technique of easy fired
The present invention relates to a kind of high-grade daily-use fine porcelain of easy fired, belong to new material of domestic ceramics and production method.
As everyone knows, ceramic industry is the big power consumer in the national economy, and the ratio that its fuel cost accounts for production cost is very high, according to statistics, is 7-15% originally abroad, increase sharply to 25-30% in recent ten years, and the present fuel cost of China is all more than 30%.At present, the firing temperature of high-grade daily-use fine porcelain is all between 1230-1450 ℃ both at home and abroad, according to about 1300 ℃ products that burn till of measuring and calculating, 100 ℃ of the every reductions of firing temperature, 20-30% capable of saving fuel, and also greatly prolong the work-ing life of kiln and kiln furniture material, and comprehensive production cost will reduce greatly.In recent ten years, consuming excessively of the energy caused global energy dilemma, and energy consumption determined the existence of industry in Mirae Corp.'s structure.Therefore, how developing the new material of a kind of both easy fireds, save energy and superior performance, is the problem that present domestic ceramics circle is attracted attention.
Up to the present, no matter be to be traditional daily-use fine of main body flux with the potassium felspar sand, still be the Albite porcelain of main body flux with the albite, firing temperature is all higher, disclosed as " Chinese patent " on October 26th, 1988, application number is: 88105656, the applying date: on January 16th, 88, applicant: Ceramics Inst., Hunan Prov., denomination of invention is: Albite porcelain, firing temperature are 1190-1320 ℃, and the easy high temperature deformation of product, suitability for industrialized production is difficult to strict control, and product only can reach daily-use fine device " GB3532-83 " standard.
Purpose of the present invention, be to overcome the problem that above-mentioned prior art exists, provide a kind of and both reduced energy consumption and production cost, satisfied the requirement of high-grade daily-use fine porcelain internal performance and visual appearance again in the new material of high-grade daily-use fine porcelain that is not more than easy fired under 1200 ℃ the temperature.
The objective of the invention is to realize in the following way:
Essential mineral is formed and is comprised mineral such as kaolin, bonding clay, feldspar and quartz, the invention is characterized in: the main body flux of this porcelain base is by potassium felspar sand and albite or is rich in the mixed flux of the mineral composition of potassium felspar sand, albite, in the blank chemical constitution, K 2The content of O is 1.0-3.0%wt, Na 2The content of O is 0.9-2.49%wt.

In the production technique of the high-grade daily-use fine porcelain of easy fired of the present invention, it burns till and is double-firing process, and base substrate is 1140-1200 ℃ of biscuiting, and glaze firing is 1050-1120 ℃, and the biscuiting temperature is not more than 1200 ℃.
Adopt the expressivity mineral composition (%wt) of potassium felspar sand, albite to be in the blank of the present invention:
The quartzy 20-30 potassium felspar sand of kaolin 40-50 7-20
Albite 5-20 calcium magnesium mineralizer reserves 1-5, wherein prominent feature is a potassium felspar sand, the consumption of albite.
In the blank for the expressivity mineral composition (%wt) of albite be with porcelain stone:
1, kaolin 40-50
Potassium felspar sand 3-6
Porcelain stone 40-50
Mineralizer 1-2
2, kaolin 42-50
Potassium felspar sand 5-8
Porcelain stone 38-50
Mineralizer 2-4
3, kaolin 40-50
