Chemical Industry Classification Knowledge

Chemical Industry Classification Knowledge
Chemical industry, chemical engineering, and chemical technology are all referred to as chemical industry for short. The chemical industry includes petrochemical, agricultural chemical, chemical medicine, polymer, paint, oil, etc. They appear in different historical periods and have different meanings, but they are closely related, interpenetrating, continuous, and endowed with new content in the course of their development.
