Abstract

The invention relates to a brown glass clarifying agent and a preparation method thereof. The brown glass clarifying agent is prepared from the following components in parts by weight: 8-10 parts of industrial salts, 24-26 parts of gypsum, 26-30 parts of anhydrous sodium sulfate and 44-56 parts of calcite, wherein the grain size of the industrial salts is 300-400 meshes, the grain size of the gypsum is 200-300 meshes, the grain size of the anhydrous sodium sulfate is 200-300 meshes, and the grain size of the calcite is 200-300 meshes. The brown glass clarifying agent is environmentally-friendly, and can effectively eliminate air bubbles in molten glass.

Description

technical field [0001] The invention belongs to the technical field of glass production technology, in particular to a brown glass clarifier, and also to a preparation method of the brown glass clarifier. Background technique [0002] Brown glass is a functional glass that absorbs ultraviolet and infrared rays. Brown glass is generally colored with sulfur carbon, and it is difficult to clarify the batch materials during the melting process. Glass emits a lot of gas during the melting process, which is because of various minerals (such as feldspar), metal salts (such as barium carbonate), oxides (such as SiO 2 ) The reaction products released by chemical reactions such as decomposition and melting. They are inevitable products in the glass production process, and at the same time, they are redundant reaction products free from the glass structure, called gaseous inclusions, generally called "bubbles". The existence of these bubbles will have a fatal impact on the final glas...
