1. Introduction
In modern industrial production, the emission problems of volatile organic compounds (VOCs) are becoming increasingly serious, not only causing pollution to the environment, but also posing a threat to human health. To address this challenge, scientists and engineers have developed a variety of technologies and methods to reduce VOC emissions. Among them, Jeffcat TAP amine catalysts are excellent in reducing VOC emissions as an efficient catalyst. This article will introduce in detail the working principle, product parameters, application fields and strategies for reducing VOCs of Jeffcat TAP amine catalysts.
2. Definition and harm of VOC
2.1 Definition of VOC
Volatile organic compounds (VOCs) refer to organic compounds that are easily volatile at room temperature, including benzene, di-dimethyl, formaldehyde, etc. These compounds are widely present in industrial production processes, such as coatings, adhesives, printing, chemicals and other industries.
2.2 Hazards of VOC
The harm of VOC to the environment and human health is mainly reflected in the following aspects:
- Environmental Pollution: VOC is one of the main components of photochemical smoke, which will lead to a decrease in air quality and form haze.
- Health Hazards: Long-term exposure to VOC can lead to headaches, nausea, respiratory diseases, and even cancer.
- Greenhouse effect: Some VOCs have greenhouse effects, aggravating global climate warming.
3. Overview of Jeffcat TAP amine catalysts
