Water-based production processes use water as the primary solvent or dispersion medium. They are widely used in a variety of industries, including coatings, adhesives, inks, leather, textiles, and plastics. Compared to traditional solvent-based processes, their advantages primarily lie in environmental friendliness, safety, cost control, and application flexibility. Specifically, they are as follows:
1. Significantly Improved Environmental Performance
Reduced Volatile Organic Compound (VOC) Emissions
Traditional solvent-based processes rely on organic solvents such as toluene, xylene, and esters. These substances are volatile during production and use, contributing to smog and photochemical smog, and some are toxic. Water-based processes, using water as the dispersion medium, can reduce VOC emissions by over 50%-90%, effectively minimizing atmospheric pollution and complying with increasingly stringent global environmental regulations (such as China's VOCs Pollution Prevention and Control Action Plan and the EU REACH Regulation). Reduced Hazardous Substance Release
Water-based systems contain no or only minimal amounts of toxic and hazardous solvents, resulting in virtually no irritating odor during the production process. They also reduce residual harmful substances like formaldehyde and heavy metals, further complying with green product standards and being more environmentally friendly and health-conscious.
2. Significantly Improved Production Safety
Reduced Fire and Explosion Risks
Organic solvents, such as gasoline and acetone, are often flammable and explosive, requiring strict fire and explosion prevention measures during storage, transportation, and production. Water, however, is non-flammable and non-combustible. Water-based processes fundamentally reduce flammability and explosion hazards, lowering workplace fire safety requirements and the probability of accidents.
Improved Working Environment
Volatilized organic solvents in solvent-based processes can irritate workers' respiratory tract, skin, and eyes, and long-term exposure can lead to occupational illnesses. Water-based processes are odorless, resulting in improved workshop air quality and significantly improved worker comfort and health.
