New re-use applications are needed to address the relatively large quantity of waste electronic products generated in the world. Cathode-ray tubes (CRTs) from computer monitors and TV sets are a large component of such waste (Mear, F. 2006) Lead and polybrominated flame retardants are the two hazardous materials that can be found in electronic appliances. Particularly, cathode ray tubes (CRT, see figure 3) contain leaded glasses. In a computer monitor, over 98% of the lead is in the CRT. This material is generally not accepted for reuse as a component; only those from televisions can be reused (Menad, N. 1999)

 

The mechanical/physical method for the treatment of CRT screen was developed. Electrical thermal belt are used to heat and separate. A thermal-expansion burst method to separate funnel and panel glass of CRT with the favor of engraving lines is developed, which is companied with a cost of 11,000 USD on self- designed equipment (see fig 4). The stability of the machine has still been tested within its commissioning practice.
