Problems solved by technology

[0002] Scarlet glass is a material for making glass handicrafts and glass decorations, but the production of scarlet glass has extremely strict requirements on the process. Because the sulfur-selenide compound is very volatile, it is difficult to obtain scarlet glass with uniform color. The existing production technology is single crucible production, the process is complex, the production efficiency is relatively low, and there are many human and environmental factors

Embodiment 1

[0017] Embodiment 1: a kind of scarlet glass and its production process, the main steps are as follows:

[0018] 1. First, weigh the raw materials according to the following weight ratio: SiO 2 68 copies; B 2 o 3 4 parts; ZnO 8.5 parts; Na 2 O 15.5 parts; K 2 2.8 parts of O; 0.4 parts of table salt; 2.4 parts of cadmium red.

[0019] The B 2 o 3 With boric acid (H 3 BO 3 ) form introduced; Na 2 O with soda ash (Na 2 CO 3 ) form introduction; K 2 O with potassium carbonate (K 2 CO 3 ) form is introduced.

[0020] 2. Mix the raw materials evenly with a V-type mixer and put them into an electric mixing kiln for melting, heating to 1200-1300°C;

[0021] 3. According to the principle of the connecting pipe, the melted glass flows into the clarification tank through the ascending passage for clarification. The temperature of the ascending passage is controlled at 1050-1200°C, and the clarification temperature is 1350-1450°C;

[0022] 4. The clarified glass flows in...

Embodiment 2

[0024] Embodiment 2: the difference from Example 1 is that the raw materials are in the following weight ratio: SiO 2 60 copies; B 2 o 3 4 parts; ZnO 9 ​​parts; Na 2 O 18 parts; K 2 2.8 parts of O; 0.4 parts of table salt; 3.2 parts of cadmium red.

Embodiment 3

[0025] Embodiment 3: the difference from Example 1 is that the raw materials are in the following weight ratio: SiO 2 62 copies; B 2 o 3 4 parts; ZnO 11 parts; Na 2 O 16 parts; K 2 3 parts of O; 2.0 parts of cadmium red.

Abstract

The invention discloses bright red glass and a manufacturing method thereof. The bright red glass comprises the following raw materials in parts by weight based on oxides: 50-80 parts of SiO2, 1-6 parts of B2O3, 7-12 parts of ZnO, 10-20 parts of Na2O, 1-4 parts of K2O, and 1-8 parts of cadmium red, wherein the raw material namely the B2O3 is led in the manner of boric acid; the Na2O is led in the manner of sodium carbonate; and the K2O is led in the manner of potassium carbonate. The raw materials which are uniformly mixed are put in a glass tank furnace for melting, clarification and stirring so as to obtain new materials, and the new materials are injected into a mold, so that the bright red glass which is good in coloring, consistent in color and free from color difference, and has patterns is obtained. The production technology is simple to operate, and easy to control, the coloring uniformity is good, and the product quality is stable. The production manner is continuous without a break, and the bright red glass is Pb-free, pollution-free, and high in production efficiency.

Description

technical field [0001] The invention relates to the field of glass preparation, in particular to scarlet glass and a preparation method thereof. Background technique [0002] Scarlet glass is a material for making glass handicrafts and glass decorations, but the production of scarlet glass has extremely strict requirements on the process. Because sulfur-selenide compounds are extremely volatile, it is difficult to obtain scarlet glass with uniform color. The existing production technology is single crucible Type production, complex process, relatively low production efficiency, and many human and environmental factors. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a scarlet glass with good coloring, consistent color without color difference, stable product quality, high production efficiency, and continuous mass production. [0004] In order to solve the above-mentioned technical problems, the technical soluti...
