What is a chemical plant?

A chemical plant is an enterprise engaged in the production and development of the chemical industry.

Any technology that uses chemistry to change the composition or structure of a substance or to synthesize a new substance is a chemical production technology, or chemical process, and the resulting products are called chemicals or chemical products. In the beginning, the production of such products was handmade workshops, which later evolved into factories and gradually formed a specific production industry, namely the chemical industry.

The chemical industry, fierce competition among enterprises, on the one hand, because of the reaction process of the in-depth understanding of the production of some traditional basic chemical products can be increasingly large-scale production units, in order to reduce costs. At the same time, due to the rise of the new technological revolution, the chemical industry has put forward new requirements, promote the technological progress of the chemical industry, the development of fine chemicals, ultra-pure substances, new structural materials and functional materials.

Expanded Information:

Chemical materials are divided into the following five categories:

1. Non-metallic

Silicate materials refer to glass, ceramics, cement and enamel and so on. They are containing silicate ores as raw materials for production, widely used as building materials, can also be used as daily necessities and arts and crafts products. Glass and ceramics, although brittle and fragile is its main drawback; but because of the raw materials are easy to get, simple production process, the chemical stability of the product is good, but also has the advantages of high hardness, heat and corrosion resistance, etc., the use of a very wide range of production is very large, and is still under continuous development.

2, polymer materials

Mainly includes plastics, chemical fibers and rubber three categories. One of the many varieties of synthetic materials, they are produced by the petrochemical monomer, after the polymerization reaction and made. Some have natural materials can not reach the special properties, widely used in industrial and agricultural production and daily life, so the development of a rapid. 30 years of the world production of polymer materials has not exceeded 100kt, to the 80's has reached about 80Mt, plastics accounted for 3 / 4. As plastics are lighter than the metal, so the volume, its production has long exceeded the metal materials today.

3, chemical fibers

Including man-made fibers as raw materials through chemical processing and production, in the 20 ~ 30 years has been popular, but its output is limited by the source of natural fibers. Synthetic fiber products appeared in the mid-1940s, the source of raw materials for the rich petrochemical products. There are many varieties of chemical fibers, and then there are filament, staple, bristle, elastic, and a variety of shaped silk.

4, rubber

is a strategic material. Natural rubber grows only in tropical and subtropical areas, not rubber-producing countries will be blocked to consider the war, are extremely important to the establishment of synthetic rubber industry on the basis of petrochemicals. Synthetic rubber varieties, some varieties than natural rubber has better heat resistance, cold resistance, oil resistance and other properties. The largest consumption of rubber is to do tires, but also used to make hoses, tapes, rubber shoes, molds silicone rubber, and latex products.

5, composite materials

is a new type of structural material. It is characterized by volume than the strength, volume than the stiffness and corrosion resistance are more than metal materials. It consists of synthetic resins, metals or ceramics and other matrix materials and inorganic or organic synthetic fibers and other reinforcing materials composed of composite materials. Base material and reinforcing materials are a variety of, and thus can be selective cooperation, in order to produce performance in line with the requirements of the emergence of a variety of composite, so that the chemical materials have a broader outlook.
