We can protect our health to a certain extent by understanding the hazards of solvents, which are the most hazardous material components in solvent-based coatings for environmental pollution and human health. The toxicity of solvents refers to both the toxic effect of solvents on human body. Toxic solvents can be absorbed by the body through the skin and digestive tract and cause poisoning. The common toxicity of most organic solvents to the human body is in high concentrations of vapor contact performance of anesthetic effects.

No catalyst can catalyze water into oil because catalysts can only catalyze reactions that can actually occur, and they cannot help with reactions that cannot occur in the first place. For example, the ammonia reaction and the oxidation of sulfur dioxide are reactions that can actually occur, but in general these reactions proceed more slowly, so they need the help of a catalyst.

At present, the world refining catalyst market is mainly monopolized by companies such as CraceDavison, Albemarle and Engelhard. China has its own unique advanced technology and mature production system for the development and use of refining catalysts, and various types of refining catalysts have been formed in series, and the technology has gradually caught up with various foreign catalysts, and has independent and independent process-specific advantages.
