What is a chemical plant?
Question 2: What chemical plants are mainly produced? Chemical plants mainly produce chemical products: chemical reagents and other fine chemical products. There are mainly inorganic reagents, organic reagents, biochemical reagents and clinical chemical reagents, reagents for environmental science, and reagents for optical and electronic industries; Military and civilian luminescent materials; Photosensitive materials for film and photography; Printing chemicals; Adhesives, plastic additives, surfactants, leveling agent, additives, denaturants, emulsifiers, flame retardants, antistatic agents, etc.
Question 3: What is chemical industry? Chemical industry, chemical engineering and chemical technology are all referred to as chemical industry for short. The chemical industry includes agrochemicals, chemicals, pharmaceuticals, polymers, paints, oils and fats, etc. They appeared in different historical periods, each with different meanings, but they are closely related, interpenetrating and continuous, and have been given new contents in their development. The early life of human beings depends more on the direct use of natural materials. Gradually, the inherent properties of these substances can not meet the needs of human beings, so various processing technologies have emerged, which consciously and purposefully transform natural substances into new substances with various properties and gradually put them into practice on the scale of industrial production. Broadly speaking, any chemical method that changes the composition or structure of a substance or synthesizes a new substance belongs to chemical production technology, that is, chemical process, and the products obtained are called chemicals or chemical products.
Simply put, chemical engineering is the process of processing one or more raw materials for economic or other purposes, so that they react chemically to produce the products they have learned. This process is usually implemented on a factory scale.
Question 4: What are the positions of the warehouse keeper and cashier in general chemical plants? Financial accounting, cashier; Technical personnel; Quality inspector of quality inspection department; Restaurant staff; Then there are various leaders.
Question 5: What is the chemical industry? Chemical industry, chemical engineering and chemical technology are all referred to as chemical industry for short. The chemical industry includes agrochemicals, chemicals, pharmaceuticals, polymers, paints, oils and fats, etc. They appeared in different historical periods, each with different meanings, but they are closely related, interpenetrating and continuous, and have been given new contents in their development. The early life of human beings depends more on the direct use of natural materials. Gradually, the inherent properties of these substances can not meet the needs of human beings, so various processing technologies have emerged, which consciously and purposefully transform natural substances into new substances with various properties and gradually put them into practice on the scale of industrial production. Broadly speaking, any chemical method that changes the composition or structure of a substance or synthesizes a new substance belongs to chemical production technology, that is, chemical process, and the products obtained are called chemicals or chemical products. In the early days, chemicals were produced by manual workshops, then evolved into factories, and gradually formed a specific production department, namely the chemical industry. With the development of productivity, some production departments, such as metallurgy, oil refining, paper making and leather making, have been separated from the chemical industry and become independent production departments. With the rapid development of large-scale petroleum refining industry and petrochemical industry, based on chemistry, physics and mathematics, combined with other engineering technologies, the discipline of chemical engineering was born and developed rapidly. This discipline studied the laws of chemical production process and solved many engineering and technical problems in the process of production scale expansion and large-scale, thus raising the production of chemical industry to a new level and entering a new stage of theory and prediction from an empirical or semi-empirical state.
In order to survive and develop, human beings constantly struggle with nature and gradually deepen their understanding of the surrounding world, thus mastering the ability to conquer nature and transform the world. After long-term historical practice, human beings are better at using natural conditions and creating a rich material world for themselves.
In ancient times, people's lives depended more on the direct use of natural substances or the extraction of needed substances. Because the inherent properties of these substances can not meet people's needs, various processing technologies have emerged, which transform natural substances into new substances with various properties and gradually put them into practice on the scale of industrial production. Anyone who changes the composition or structure of a substance or synthesizes a new substance by chemical means belongs to chemical production technology, that is, chemical process; The obtained products are called chemicals or chemical products. In this way, many substances that are not found in nature are constantly created. At first, it was a manual workshop to produce such products, and later it evolved into a factory, and gradually formed a specific production department, namely the chemical industry. With the development of productivity, some production departments, such as metallurgy, oil refining, paper making and leather making, have been separated from the chemical industry and become independent production departments. With the rapid development of large-scale petroleum refining industry and petrochemical industry, chemical engineering based on chemistry, physics and mathematics and combined with other engineering technologies has been further improved to study the laws of chemical production process and solve many engineering and technical problems in scale expansion. It raises the production of chemical industry to a new level, and enters a new stage of theory and prediction from an empirical or semi-empirical state (see History of Chemical Engineering Development), which makes the chemical industry increase a lot of material wealth for human beings with its creative ability of mass production and accelerates the development of human society.
In modern Chinese, chemical industry, chemical engineering and chemical technology are all called chemical engineering for short. They appear in different historical periods and have different meanings, but they are closely related and penetrate each other. In people's minds, the word "chemical industry" has long been synonymous with the general category of knowledge and occupation. Its significance in national economy and engineering technology has aroused people's extensive interest and attracted thousands of people to join in it. The following briefly explains the rich and colorful contents and important contributions of the chemical industry from all aspects of human social life.
Fine chemicals industry
Fine chemical industry is the general name of the industry that produces fine chemicals, referred to as "fine chemical industry" for short. The meaning of fine chemicals is still under discussion abroad. At present, anyone who owns a book.
Question 6: What do ordinary chemical plants produce? Chemical plants are generally divided into large chemical enterprises and small chemical enterprises. Big chemical industry refers to petrochemical industry, coal chemical industry, etc. All these are many separation towers, etc. Small chemical industry generally produces chemical raw materials for foundation nails, including medical raw materials.
Question 7: What is the job of the chemical industry? China's economy is developing gradually, and the level of science and technology is also improving gradually. In the past, chemical production was generally operated on site, but now production is operated in the general control room, which is at a certain distance from the site to ensure the safety of workers. See what kind of enterprise and workshop you are in. Small enterprises can produce on the spot. On-site production is dangerous, so it is best to enter some well-paid companies to ensure your own life safety!
Question 8: What do you mean by "material leakage" in chemical plants? Material leakage generally refers to the leakage of materials originally in pipelines or pressure vessels to the external environment, mainly referring to most liquid materials.
Question 9: What are the ten characteristics of chemical plants? Proportion of platinum catalyst QMA-4 10X:
A. When premixes such as liquid silicone rubber and electronic potting compound are prepared, they are added in an amount of 2.0-8.0ppm based on the total mass, and then fully mixed.
B, when preparing raw materials such as silicone release agent and pressure sensitive adhesive, add 100~ 150ppm according to the formula, and then mix evenly;
● Mix the catalyst-added component A and the catalyst-added component B in proportion, fully mix them and shape them according to the actual molding process.
● The recommended curing condition is 120℃/ 180-300s, or it can be adjusted according to the formula.
● The optimum catalyst addition ratio and curing conditions should be determined according to different products and production processes.
Question 10: What is the primary water of a chemical plant? The water used when the water plant enters the chemical plant may be waste water after discharge, and it can be reused after treatment. It is secondary water.
