Problems solved by technology

However, this kind of processing method needs to be included in the cost of red PVB film and film matching, so as to increase the unit consumption
In addition, colored glaze technology can also obtain the visual effect of red glass, but this method will greatly reduce the transmittance of the glass, the practical effect is not good, and it has not been widely used.

Abstract

The invention relates to a red colored glass. The red colored glass is obtained by subjecting the Sn<2+> in float white glass and the Cu<2+> contained in the glass coating of a float white glass tin rich side to displacement and redox reaction, and performing position replacement by the reduction product Cu<+>. The invention also provides the preparation method of the red colored glass, and its special coating and equipment. The preparation method provided in the invention is simple and has low energy consumption. The obtained red colored glass has good light transmittance and light quality in the red light range, thus solving the thermal expansion cracking problem likely to occur in traditional red glass.

Description

technical field [0001] The invention relates to a kind of colored glass, in particular to a kind of red colored glass, its preparation method and its special coating and equipment. Background technique [0002] Float glass is a kind of flat glass. Its preparation process is to melt the glass raw materials, let the glass liquid flow into the tin bath, and form a uniform thickness and polished glass ribbon on the liquid surface of the tin liquid, and detach after cooling and hardening. Liquid metal, then annealed and cut into transparent colorless flat glass. Due to the special molding process of float glass, tin infiltration is inevitable in float glass. In the process of glass preparation, the side in contact with the tin liquid is usually called the tin-rich side, and the other side is called the air side. The concentration of tin ions inside the glass gradually decreases from the tin-rich side to the air side, and is concentrated in the inner 20 from the tin-rich side. -...
