[0018] Step (2). Adjust the chemical components of the finely ground waste lead-containing glass, so that the mass percentage of each component in the finely ground waste lead-containing glass is 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 a mass ratio of CuO of 6:1.

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

Embodiment 2

[0022] Step (1). The CRT cone glass is roughly crushed to 2 mm, and after the rough crushing, it is put into a roller ball mill for fine grinding, and obtaining a particle size is that the finely ground waste lead-containing glass of 200 objects is obtained;

[0023] Step (2). Adjust the chemical components of the finely ground waste lead-containing glass, so that the mass percentage of each component in the finely ground waste lead-containing glass is 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). The finely ground waste lead-containing glass after adjusting the chemical composition is put into the mixer and mixed evenly, and then placed in the kiln for high temperature melting. The melting temperature is 980 ° C and the time is controlled to 2 h. The shape is artificially formed to obtain the formed product;

[0025] Step (4). The formed produ...

Embodiment 3

[0027] Step (1). The low-melting-point glass sealed by the CRT screen cone is roughly crushed to 3 mm, put into a roller ball mill for fine grinding after the rough crushing, and obtaining a particle size of 300 meshes of finely ground waste lead-containing glass;

[0028] Step (2). Adjust the chemical components of the finely ground waste lead-containing glass, so that the mass percentage of each component in the finely ground waste lead-containing glass is 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 a mass ratio of CuO of 3:1.

[0029] Step (3). The finely ground waste lead-containing glass after adjusting the chemical composition is put into the mixer and mixed evenly, and then placed in the kiln for high temperature melting. The melting temperature is 800°C and the time is controlled to 3 hours. 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 resource utilization, and in particular relates to a method for preparing colored glass by using waste lead-containing glass as a raw material. Background technique [0002] Lead-containing glass refers to glass that contains glass formers such as silica and a relatively high content of lead oxide. Due to its good optical properties, electrical conductivity, radiation protection properties and processability, 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 utensil glass, etc. product. As an important lead-containing glass product, cathode ray tubes (CRTs) are 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, most of which are...
