In this work, a novel and straightforward method to remove lead oxide and reuse metal lead was developed by PbO vapor vacuum decrease procedure. Under this condition, more than 98 pct of lead can be gotten rid of from waste channel glass and the Pb content in parent glass was successfully reduced to 0. 38 pct. The metallic Pb microspheres with 99. 36 pct pureness were acquired and the Pb leaching concentration of recurring glass was 1. 67 mg/L as gauged by the Toxicity Characteristic Leaching Procedure test. Radiant Tb3+ glass as an energy material making use of recurring glass was greatly luminescence performance. In general, this work provides a basic and effective procedure for the detoxing and use of waste CRT funnel glass as well as the recovery of Pb by vacuum metallurgy innovation.
In order to study the waste cathode ray tube glass fine accumulation on barite concreteperformance, the waste cathode ray tube glass great aggregate is mixed into the barite concrete at 0%, 4%, 6%, 8%, and 10% of the mass of the barite sand high quality to perform speculative research study on the related properties of barite concrete.
With the advancement of kinescope modern technology, the amount of disposed of cathode ray tubes glass remains to raise. Based on the research status on the treatment of lead-containing glass in waste CRTs, the innovations of lead separation and recycling were summed up, and their developments and characteristics were evaluated.
