Embodiment 1

[0029] Take the waste borosilicate glass slag deposited in the flue when the flame kiln produces borosilicate glass, first grind the waste borosilicate glass slag (referred to as waste glass slag, the same below), pass through a 16-mesh sieve, and separate the block Grind the large waste glass slag, then add the waste glass slag to 2.5 times the mass of water and soak for 40-50 hours, stir once every 12 hours during the soaking process, filter the soaked waste glass slag, and dry at 80-120 °C to obtain Pretreated waste glass slag.

[0030] Put the pretreated waste glass slag directly into the refractory container or high-temperature furnace, heat it at 1150°C for 1-2.5 hours to obtain molten glass, cast the molten glass to form annealed glass plate, or quench the molten glass into glass powder.

[0031] The resulting glass plate has a density ρ of 2.400 g / cm 3 , its transmittance spectrum curve is as follows figure 1 shown, from figure 1 It can be seen that the glass plate ...

Embodiment 2

[0033] Waste glass slag is directly made into glass plate or glass powder according to the method of Example 1, the difference is: in the soaking process, 1.6 times the water of its mass is added to waste glass slag, soaked for 80-96h, the performance of the gained glass plate is the same as Example 1 is close.

Embodiment 3

[0035] The stability of the glass made directly from the pretreated glass slag is not very good, so it can only be used as glass with low quality requirements such as ink bottles and paste bottles. To further increase the performance of the glass, waste glass slag can be mixed with other ingredients to make glass with improved chemical stability. The steps are: take the waste borosilicate glass slag deposited in the flue when the flame kiln produces borosilicate glass, first crush and grind the waste borosilicate glass slag (referred to as waste glass slag, the same below), and pass through 16 mesh Sieve, grind the larger blocky waste glass slag, then add the waste glass slag to 2 times the mass of water and soak for 60-70h, stir once every 12h during the soaking process, filter the soaked waste glass slag, 80 Dry at ~120°C to obtain pretreated waste glass slag.

[0036] Add 6~18% limestone to the pretreated waste glass slag, mix the two thoroughly, put them into a refractory...

Abstract

The invention discloses a waste glass slag reutilization method and obtained glass. The reutilization method comprises the following steps of: first, breaking waste glass slags, grinding, soaking with water to remove most soluble substances in the waste glass slags, filtering and drying the soaked waste glass slags, and directly firing into glass or using the waste glass slags as a raw materials for making glass. A method and a process for the pretreatment and the reutilization of waste borosilicate glass slags collected from a flue of a flame kiln for producing borosilicate glass are first pointedly provided by the invention, a direction is pointed out for the reutilization of the waste glass slags produced by volatile condensation, a novel feasible approach is provided, and a solution for solving the problem which puzzles borosilicate glass producing enterprises is found. With the method, filtrate and filter residues are respectively utilized after the waste glass slags are pretreated, the wastes are fully reutilized, and environment pollution is reduced.

Description

technical field [0001] The invention relates to a method for reusing waste glass slag, in particular to a method for reusing waste borosilicate glass slag and the obtained glass. Background technique [0002] Usually, waste glass is used as a renewable and reusable resource. Adding waste glass to the batch of the same type of glass can play a role in fluxing, shorten the melting time of glass, reduce production costs and improve economic benefits. In addition, waste glass can also replace flux and some clay mineral components in the production of clay bricks, as a filler for asphalt road pavement, as an admixture and aggregate for concrete, and as a glass mosaic, glass-ceramic plate, building brick, foam Raw materials for the production of glass, glass wool, glass beads, etc. [0003] Waste glass is mainly produced when all kinds of glass products are scrapped after use. In addition, in the production process of some glass, a large amount of waste glass will also be produ...
