Preparation method of black glass batch smelted by electric melting furnace

Abstract

The invention belongs to the field of daily glass production, and particularly relates to a preparation method of a black glass batch smelted by an electric melting furnace. The method mainly comprises the following steps: adding a proper amount of oxidant, clarifier and colorant into waste daily bottles and cans, vessel glass, various mineral raw materials and fluxing agent, and producing the black vessel glass by an electric melting method. The material is prepared from, by weight, 11-15 parts of waste daily bottles and cans and vessel glass, 56-60 parts of ordinary sand, 9-12 parts of potassium feldspar powder, 2-2.5 parts of ulexite powder, 0.2-0.4 part of zinc oxide, 0.3-0.5 part of witherite powder, 2.7-3.5 parts of manganese powder, 0.6-1.0 part of apatite powder, 0.6-1.0 part of chromium ore powder, 10-12 parts of sodium carbonate and 0.15-0.3 part of cerium oxide. The material is low in cost, and has the advantages of environmental protection, energy conservation, good glass quality and the like.

Description

technical field [0001] The invention belongs to the field of daily-use glass production, and in particular relates to a method for preparing black glass batch materials melted in an electric melting furnace. Background technique [0002] Black glass is glass that can absorb all visible light. In Europe, America, the Middle East and other regions, black is a color with special charm. Tableware made of black glass, such as bowls, basins, plates, cups, pots, etc., has a dignified, majestic and calm style, and is favored by the public. Therefore, the product has a broad market. [0003] It is very difficult to melt black glass with a pool furnace, because the molten glass in the pool furnace is heated on the surface of the molten glass, but the heat permeability of black glass is very poor, most of the melting heat is absorbed by the surface glass, and it is difficult for the heat to penetrate downwards. If the temperature of the molten glass is too low, defects such as bubble...

Problems solved by technology

[0003] It is very difficult to melt black glass with a pool furnace, because the molten glass in the pool furnace is heated on the surface of the molten glass, but the heat permeability of black glass is very poor, most of the melting heat is absorbed by the surface glass, and it is difficult for the heat to penetrate downwards. If the temperature of the molten glass is too low, defects such as bubbles, stones, and crystallization cannot be eliminated, making it difficult to melt the ideal black glass

[0004] The crucible furnace can melt high-quality black glass, but it consumes a lot of energy and has low production capacity, so it cannot be mass-produced to meet market demand
