A Study on Explosion Characteristics of Toner Powder
Toner powder is an important constituent of a toner cartridge for a laser printer and has potential hazards of combustion and explosion because of its physicochemical characteristics. In this paper, physicochemical, combustible and explosive characteristics of hpQ2612A toner are investigated experimentally. The mean size of the toner powder is about 2.45 μm and it has several organic groups such as carboxyl group, hydroxyl group and carbonyl group which make the toner dust much easier to combust. The TG-DSC curves show that the toner dust is combustible and the combustion process starts at about 368 ℃. The dust explosion characteristics of the toner dust were, respectively: MIE=5~30 mJ, Pmax=0.74 MPa, (dP/dt)max=100.5 MPa/s, LEL=40~50 g/m3. These results reveal that the toner powder is a dangerous industry dust and has the possibility to make tragedy such as combustion or even explosion.
