Formula and preparation method of national flag bright red glazed brick

Abstract

The invention relates to a formula and preparation method of a national flag bright red glazed brick. On the basis of not changing the existing glazed brick production technique too much, the invention mainly adjusts and optimizes the composition of blank materials, the composition of base / cover coating fused blocks, the preference and proportion of the fused blocks having different properties in base / cover coating, the processing technique of the cover coating, the formula composition of the base coating, the water absorptivity of a biscuit, the firing temperature and the like, thereby ensuring that the fired national flag bright red glazed brick has a dazzlingly beautiful glaze color, is bright like a reflective mirror, and has a high decorative effect and an artistic aesthetic effect; and the color is as pure as the color of a national flag and is glossy and bright, so that the national flag bright red glazed brick can shine like the rising sun. Meanwhile, the technology has high universality, and is readily popularized in the industry.

Description

technical field [0001] The invention relates to a formula of national flag bright red glazed brick and a preparation method thereof. Background technique [0002] The big red glaze is especially like the big red glaze of the national flag. It is as bright as a mirror, bright as the sun, bright red in color, moist and bright. It is one of the most precious glazes in ceramic color glazes. Symbolizing festiveness, it is a color that people have always liked, but this kind of bright red glazed ceramic product, which is like the color of the national flag, is the most difficult to fire. Its color is extremely unstable at high temperature, and it is very harmful to the atmosphere of the kiln during firing. It is sensitive, and the expected effect cannot be achieved if there is a slight variation, so it is very difficult to obtain relatively pure bright red glazed ceramic products such as the national flag color.

[0002] The big red glaze is especially like the big red glaze of the national flag. It is as bright as a mirror, bright as the sun, bright red in color, moist and bright. It is one of the most precious glazes in ceramic color glazes. Symbolizing festiveness, it is a color that people have always liked, but this kind of bright red glazed ceramic product, which is like the color of the national flag, is the most difficult to fire. Its color is extremely unstable at high temperature, and it is very harmful to the atmosphere of the kiln during firing. Sensitive, a slight variation will not achieve the expected effect, so it is not easy to obtain relatively pure red glazed ceramic products such as the national flag color

How many ceramic technicians in the past have devoted a lot of effort to mass-fire this precious glaze, but they can occasionally produce one or two products in the process of continuous exploration, but mass production often fails.

But at low temperature (lower than 1000°C), this bright red color is relatively stable and easy to control, but the amount of lead and cadmium dissolved in ceramic products fired at low temperature does not meet the requirements, which will cause harm to human health during use. harm
