The production cost of this method is high, and the product is expensive
In addition, the crystallization texture of the existing glass-ceramics is relatively monotonous, only fine particles, and the color system is not rich enough, and the colors are only ordinary white, yellow, green and dark brown, etc. The application effect of its products in high-end building decoration is seriously affected. Therefore, the production and sales of the existing glass-ceramics are already struggling, and gradually faded out of the construction and decoration industry

Abstract

A method for producing a microcrystalline jade panel with the iridescent entire body by the utilization of a roller kiln comprises the following steps: (1) microcrystalline glass frits in multiple colors are prepared; (2) a chromophoric auxiliary agent is prepared; (3) a kiln furniture is manufactured; and (4) the above microcrystalline glass frits in all colors are distributed through an automatic distribution device on a fireproof backing plate according to a predetermined mode for 1-5 times, and the chromophoric auxiliary agent is applied occasionally to make the total thickness of the frits reach 12-40 mm; and the frits are fired in a roller kiln. The firing period is 2-8 hours. The firing curve is as follows: the temperature rises from normal temperature to 800-1050 DEG C within 30-120 min; the temperature rises to 1000-1250 DEG C within 60-240 min; the temperature cools to 850-580 DEG C within 90-360 min; and the temperature cools to normal temperature within 120-480 min before drawing. By the method, the produced microcrystalline jade panel with the iridescent entire body has natural iridescent patterns and entire texture effect as natural stones. The method has advantages of low production cost and high production efficiency.

Description

technical field [0001] The invention relates to the technical field of architectural glass-ceramic plates, in particular to a method for producing full-body illusion micro-crystalline jade plates by using a roller kiln. Background technique [0002] Glass-ceramics for building material decoration originated in Japan in the 1970s. The production of its plates is fired in a shuttle kiln or tunnel kiln. The firing cycle is very long, generally more than 20 hours. The production cost of this method is very high, and the product is expensive. In addition, the crystallization texture of the existing glass-ceramics is relatively monotonous, only fine particles, and the color system is not rich enough, and the colors are only ordinary white, yellow, green and dark brown, etc. The application effect of its products in high-end building decoration is seriously affected. Therefore, the production and sales of the existing glass-ceramics are already struggling, and gradually fade out ...
