The plastic injection molding machine mainly produces organic waste gas during granulation and extrusion. The temperature of granulation and extrusion process is generally high, about 170 ~ 210 ℃. The processing links of different products are different, but it can't be higher than the thermal decomposition temperature of plastic raw materials.
The composition of waste gas generated in granulation process is complex. The composition of waste gas generated by different raw materials is different. Most of the injection molding waste gas is mainly composed of acetaldehyde, methanol and organic waste gas generated by engineering plastics.
Process flow of waste gas treatment of injection molding machine: waste gas collection; Low temperature plasma waste gas treatment equipment, activated carbon adsorption equipment / photolysis waste gas purification equipment, centrifugal fan, 15m chimney discharge at high altitude
