2. Sources and hazards of VOC emissions
2.1 Definition of VOC
Volatile organic compounds (VOCs) refer to organic compounds that are easily volatile at room temperature, mainly including alkanes, olefins, aromatic hydrocarbons, aldehydes, ketones, etc. These compounds are widely present in industrial production, especially in chemical, coating, printing and other industries.
2.2 VOC sources in polyurethane production
In the polyurethane production process, VOC mainly comes from the following aspects:
- Raw material volatility: Some solvents and additives used in polyurethane production will volatilize during the reaction.
- Side reaction products: In polymerization reaction, some intermediate or by-products will be released in the form of VOC.
- Post-treatment process: During the foam curing, cutting and other post-treatment process, some unreacted raw materials or by-products will evaporate.
2.3 Hazards of VOC
- Environmental Pollution: VOC is the main precursor of photochemical smoke, causing serious pollution to the atmospheric environment.
- Health Hazards: Long-term exposure to VOC can cause damage to the human respiratory system, nervous system, etc., and even cause cancer.
- Safety Hazards: Some VOCs have the characteristics of flammability and explosion, which increases safety risks during the production process.
