Embodiment Construction

[0010] Below in conjunction with embodiment the present invention will be further described

[0011] The preparation of the color glass blue colorant referred to in the present invention is realized through the following process.

[0012] 1. Preparation of flux

[0013] In order to adapt to the working temperature of the forehearth and the chemical composition and chemical properties of the glass base material. Reduction of PbO,B 2 o 3 Etc. The volatilization of raw materials, the flux is selected from the following raw material ratio: SiO 2 30-35%; AI 2 o 3 3-5%; CaO0.5-2%; MgO0.1-1%; PbO45-50%; 2 o 3 4-8%;K 2 O+Na 2 O10-15%.

[0014] 2. Preparation of molten glaze powder

[0015] The flux is formulated according to the above ratio and then melted into a glass body in a crucible. The melting temperature is about 1180°C, and the highest temperature is kept for 45 minutes. Then it is poured into water for water quenching. The molten glaze after water quenching is bal...

Abstract

The present invention is colorant for color glass and its preparation process. The granular blue colorant for color glass is prepared with Pb and B as basic components and added Zn, Cr and Li components, and through the technological process including compounding flux, preparing glaze melting powder, compounding pigment, preparing colorant and other steps. The new type of colorant has stable quality, good use effect and low production cost.

Description

technical field [0001] The invention relates to a glass colorant compound and a preparation method. Background technique [0002] At the end of the 1960s, colored glass began to appear abroad. my country began to study it in the 1970s. At first, powdered pigments were added to the road. After the pigments were melted, they were stirred to mix with the basic glass into a uniform substance. After forming, however, this color glass has only received limited promotion. First, there are many difficulties when adding colorants to the molten glass, and second, secondary heating of the molten glass has adverse effects, the main problem being the occurrence of secondary bubbles. Finally, the granular coloring agent imported from the United States is used. The coloring agent generally adopts a boron-containing formula. Although it has been improved, the product quality is still unstable, and defects such as color channels, bubbles, and color blocks are very easy to appear, and the pro...
