[0018] Step (2). Adjust the chemical components of the finely ground waste lead-containing glass, so that the mass percentages of each component in the finely ground waste lead-containing glass are as follows: 55% SiO 2 , 0.1﹪B 2 o 3 , 1﹪ZnO, 3﹪CaO, 2.5﹪BaO, 12﹪Na 2 O, 0.3﹪K 2 O, 20﹪PbO, 6﹪Al 2 o 3 、0.03﹪Er 2 o 3 , 0.07% green colorant; the green colorant is Cr 2 o 3 A mixture with CuO in a mass ratio of 6:1.

[0019] Step (3). Put the finely ground waste lead-containing glass after adjusting the chemical composition into the mixer and mix it evenly, then put it in the tank kiln for high-temperature melting. The melting temperature is 750 °C and the time is controlled for 6 hours. According to the design The shape is artificially formed to obtain ...

Embodiment 2

[0022] Step (1). The CRT cone glass is roughly crushed to 2 mm, and then put into a roller ball mill for fine grinding to obtain a particle size of 200 mesh finely ground waste lead-containing glass;

[0023] Step (2). Adjust the chemical components of the finely ground waste lead-containing glass, so that the mass percentages of each component in the finely ground waste lead-containing glass are as follows: 65% SiO 2 , 0.2﹪B 2 o 3 , 0.2﹪ZnO, 1﹪CaO, 2﹪BaO, 7.49﹪Na 2 O, 0.4﹪K 2 O, 20﹪PbO, 3﹪Al 2 o 3 、0.01﹪Er 2 o 3 , 0.7% dark blue colorant CoO;

[0024] Step (3). Put the finely ground waste lead-containing glass after adjusting the chemical composition into the mixer and mix it evenly, then put it in the pool kiln for high-temperature melting. The melting temperature is 980°C, and the time is controlled for 2 hours. According to the design The shape is artificially formed to obtain the formed product;

[0025] Step (4). Send the formed product into an annealing kiln fo...

Embodiment 3

[0027] Step (1). Crushing the low-melting-point glass sealed by the CRT screen cone to 3 mm, and then putting it into a roller ball mill for fine grinding to obtain finely ground waste lead-containing glass with a particle size of 300 mesh;

[0028] Step (2). Adjust the chemical components of the finely ground waste lead-containing glass, so that the mass percentages of each component in the finely ground waste lead-containing glass are as follows: 50% SiO 2 , 0.3﹪B 2 o 3 , 1﹪CaO, 1.5﹪BaO, 5﹪Na 2 O, 0.1﹪K 2 O, 38﹪PbO, 4﹪Al 2 o 3 , 0.02﹪Er 2 o 3 , 0.08% green colorant; the green colorant is Cr 2 o 3 A mixture with CuO in a mass ratio of 3:1.

[0029] Step (3). Put the finely ground waste lead-containing glass after adjusting the chemical composition into the mixer and mix it evenly, then put it in the pool kiln for high-temperature melting. The melting temperature is 800°C and the time is controlled for 3 hours. According to the design The shape is artificially formed...

Abstract

The invention discloses a method for preparing colored glaze with waste flint glass as a raw material. The waste flint glass not only wastes the lead resource, but also has potential threats to human health and ecological environment, but no better method for treating the water flint glass exists. The method comprises the following steps of generally smashing the waste flint glass and grinding; then regulating the chemical components of the grinded waste flint glass; melting for 2-6 hours at high temperature of 750-980 DEG C; carrying out manual forming or mechanical forming according to a designed shape; sending the formed product into an annealing furnace for annealing, wherein the annealing temperature is 450-550 DEG C and the annealing time is 2-10 hours; and cooling to normal temperature so as to obtain the colored glaze. According to the method, the waste flint glass is taken as the main raw material for preparing the colored glaze, so that the method has the advantages that technological process is simple, raw material source is wide, energy consumption is low and the like, can be used for preparing colored glaze product with good gloss, low softening point and long material property, is applicable to the existing various colored glaze product factories in north and south and is beneficial to large-scale industrial production.

Description

technical field [0001] The invention belongs to the technical field of solid waste treatment, disposal and recycling, and in particular relates to a method for preparing colored glaze by using waste lead-containing glass as a raw material. Background technique [0002] Leaded glass refers to glass containing glass formers such as silica and a relatively high content of lead oxide. Due to its good optical performance, electrical conductivity, radiation protection performance and processability, etc., it is widely used in the manufacture of electric vacuum glass, low temperature sealing glass, radiation protection glass, optical glass, high refraction bead glass and art vessel glass, etc. product. Cathode ray tube (CRT), as an important leaded glass product, is widely used in electronic and electrical equipment such as televisions, computer monitors, and oscilloscopes. At present, there are about 550 million TV sets in my country, the vast majority of which are CRT TV sets, ...
