Why is the chemical industry a diversified basic industry

Chemical industry is a knowledge and capital intensive industry. With the development of science and technology, it has gradually developed into a multi industry and multi variety production department from the initial production of only a few inorganic products such as soda ash and sulfuric acid and organic products mainly made from alizarin extracted from plants. A large number of chemical enterprises with comprehensive utilization of resources and large-scale have emerged.

Including basic chemical industry and plastics, synthetic fiber, petroleum, rubber, pharmaceutical, dye industry, etc. It is a department that uses chemical reactions to change the structure, composition and morphology of substances to produce chemical products. Such as inorganic acids, alkalis, salts, rare elements, synthetic fibers, plastics, synthetic rubber, dyes, paints, fertilizers, pesticides, etc.

Chemical industry is a basic industry with many varieties. In order to meet the various needs of chemical production, there are many kinds of chemical equipment, and the operating conditions of the equipment are relatively complex. According to the operating pressure, there are vacuum, normal pressure, low pressure, medium pressure, high pressure and ultra-high pressure; according to the operating temperature, there are low temperature, normal temperature, medium temperature and high temperature; Most of the treated media are corrosive, or flammable, explosive, toxic and highly toxic.
