Problems solved by technology

[0003] However, there are certain difficulties in outsourcing and using waste tube glass, such as the support of manufacturers, the cooperation of logistics companies, the need to set up full-time recycling personnel and the establishment of a procurement network
Due to the different formulas of glass shell glass manufacturers, the transmittance of glass shell glass is not the same, and the picture tube manufacturers and TV manufacturers do not use products from a fixed supplier. Therefore, the manufacturers of waste picture tube glass shell glass purchased, The production time is uncertain and the transmittance is not stable, which brings technical difficulties to the recycling of waste picture tube glass bulbs

Abstract

This invention relates to a method for recovering and utilizing glass shell glass of waste kinescope. The method comprises: (1) classifying glass shell glass of waste kinescope into panel glass, cone glass or mixed glass, separating, washing, and pulverizing into 1-5 mm glass particles; (2) sending the glass particles to the production process of kinescope glass shell as the raw material (not higher than 30%). The method can lower the production cost, improve the melting quality of glass shell glass, reduce environmental pollution caused by abandoning glass shell glass of waste kinescope, and has high social benefit.

Description

technical field [0001] The invention belongs to the technical field of picture tube glass bulbs, in particular to a recycling method for waste picture tube glass bulbs. Background technique [0002] Waste picture tube glass refers to the fragments, leftovers, waste products and waste picture tube glass produced after the end of service life of the glass shell, picture tube and TV set manufacturers in the production process. Any manufacturers of glass bulbs, kinescopes and televisions will produce waste kinescope glass bulbs. Glass cullet is a good raw material and a good flux in the glass melting process. Because the glass shell cullet is produced by melting various raw materials in the glass shell manufacturing process, the oxides in the glass shell glass are provided by the raw materials. The recycling of waste glass shell glass can save raw materials, so glass shell cullet is a good raw material. And the cullet of the glass shell is not like the melting of the raw mate...
