Abstract

The invention discloses a preparation method of blue glass. Different trapping agents are used for separating iron oxide in potassium feldspar, and a flotation agent is used for the separation of dolomite and iron ions contained therein, so as to obtain potassium feldspar concentrate and dolomite ore concentrate with higher purity; and through the specific proportion of raw materials, the blue glass is obtained. The blue glass obtained by the method has the advantages of few impurities, high transparency, high strength, bright and uniform color, reduced costs, reduced environmental pollution, improved stability, and reinforced acid resistant performance, so that the glass is not easy weathering during use, and maintains a transparent and bright state for a long time.

Description

technical field [0001] The invention relates to a glass manufacturing process, in particular to a preparation method of blue glass. Background technique [0002] Glass is formed by melting together chemical substances such as silicon dioxide and limestone. It forms a continuous network structure when it melts. It is a silicate non-metallic material that gradually increases in viscosity and hardens during cooling to cause it to crystallize. The chemical composition of ordinary glass is Na 2 SiO 3 , CaSiO 3 , SiO 2 or Na 2 O CaO 6SiO 2 etc., the main component is silicate double salt, which is an amorphous solid with irregular structure. It is widely used in buildings, used for wind and light transmission, and belongs to the mixture. There is also colored glass that is mixed with certain metal oxides or salts to show color, such as adding cobalt, copper and other elements to make the glass appear blue. The publication number is CN103553341B, which discloses a fluorine-f...
