UV curing equipment typically produces two main types of exhaust: ozone and volatile organic compounds (VOCs). So how to effectively deal with the waste gas generated by UV curing equipment?
1. Ozone: A certain amount of ozone will be generated during UV curing. Ozone is a gas with pungent odor and strong oxidizing ability. Methods for dealing with ozone include:
- Degrade it with an ozone decomposer or ozone catalyst.
- Provide proper ventilation around UV curing equipment so that ozone is vented outside instead of accumulating indoors.
2. VOCs: Materials such as coatings and inks used in the UV curing process may contain volatile organic compounds, which are volatilized during the curing process. Methods to deal with VOCs include:
- Capture VOCs using exhaust gas collection systems and send them to air treatment units such as activated carbon filters or catalytic combustion units for treatment.
- Optimize process parameters and material selection to reduce the generation and release of VOCs.
- Implement a closed production environment or a local exhaust system to reduce the concentration of VOCs accumulated indoors.
It is necessary to select and implement a suitable exhaust gas treatment method according to the specific situation and local regulations. Professional environmental engineers or relevant agencies should be consulted to evaluate and design exhaust gas treatment systems.
