Chemical industry classification knowledge

Chemical industry, chemical engineering, chemical technology are referred to as chemical industry. Chemical industry includes petrochemical industry, agricultural chemical industry, chemical medicine, polymer, paint, grease and so on. They appear in different historical periods and have different meanings, but they are closely related, penetrate each other, have continuity, and are endowed with new contents in their development process.
