The raw material industry is a sector that provides basic materials, power and raw materials to all sectors of the national economy, including metal smelting and processing, coking and coke chemistry, chemical raw materials, cement, wood-based panel processing and other industries.
Raw material industry includes steel, nonferrous metals, petrochemical industry, chemical industry, building materials industry and so on. In the raw material industry, we need to adjust the product mix, the organizational structure of enterprises and the industrial layout, and improve the quality and technological content of our products in line with the conditions of energy and resources and the capacity of the environment.
Here’s a look at the raw material industry using vacuum pump applications:
1. Vacuum pumps are used in the petrochemical industry
The petroleum and chemical industries are industries that convert petroleum or natural gas into materials (plastics, rubber, fibers, chemicals, etc.) and process these materials into everyday items (shoes, tires, paint, clothes, etc.).
By oil or natural gas produced in petrochemical basic raw materials such as methane, ethane, ethylene, propylene, butadiene, benzene, toluene, xylene, etc., through specific manufacturing procedures, can be obtained first intermediate raw materials, the intermediate raw material after polymerization, esterification, alkylation and other manufacturing process for plastic, rubber, synthetic fiber and chemicals, such as detergents, adhesives, solvents, fertilizer, etc.
The development and utilization of alternative energy sources have been accelerated, and projects such as ethanol gasoline, biodiesel, methanol, coal-bed methane, oil shale, coal-to-oil, and coal-to-olefin are in full bloom. Methanol and coal-to-oil have shown an overheated tendency of investment.
2. Vacuum pumps are used in metallurgy and nonferrous industries
China’s metallurgical industry, after years of construction, has formed a complete industrial system consisting of mining, sintering, coking, ironmaking, steelmaking, steel rolling and the corresponding ferroalloys, refractory materials, carbon products, geological exploration, engineering design, construction, scientific research and other sectors.
3. Vacuum pumps are used in building materials industry
Building materials industry is an important one in China. Building materials products include three categories: building materials and products, non-metallic minerals and products, and inorganic non-metallic new materials, which are widely used in construction, military industry, environmental protection, high-tech industry and people’s life.
4. Vacuum pumps are used in the rare earth industry
In the early days of the People’s Republic of China, many people were puzzled when foreign companies traveled thousands of miles to collect the slag we used as scrap. It was not long before it was discovered that what they really wanted was some of the rare-earth elements found in the slag.
In general, rare earth elements include 16 chemical elements including lanthanum (La), cerium (ce), praseodymium (Pr), Nd (Nd), promethium (Pm), samarium (Sm), Eu (Eu), gadolinium (Gd), terbium (Tb), dysprosium (Dy), Ho (Ho), erbium (Er), thulium (Tm), ytterbium (Yb), lutetium (Lu), yttrium (Y), among which promethium (Pm) is a radioactive element.
Rare earth plays an important role in industry. Almost all electric machines, from sophisticated military machines to ordinary household appliances, rely on magnetic materials. If the ndfeb permanent magnet material is used, the efficiency of the motor and the overall level of the product can be greatly enhanced and the industrial level of the whole society can be greatly improved. The starter of electric vehicle USES neodymium iron boron permanent magnet material, the starting power will greatly increase, but the volume will greatly reduce; In the future, the new generation of variable frequency air conditioners, washing machines and other household appliances will use ndfeb permanent magnet material, which will significantly reduce the energy consumption and further improve the performance. In addition, this material has a wide application prospect in digital optic disc, maglev high-speed train, automatic expressway and so on. However, after adding 30 percent of neodymium to the original permanent magnet material, the material price will be changed from 4,000 yuan/ton to 1 million yuan/ton.
5. Vacuum pumps are used in the paper industry
Paper industry is an important industry closely related to the development of national economy and the construction of social civilization. In developed countries, the consumption of paper and paperboard and its growth rate keep pace with the growth of GDP. The role it plays in the modern economy has attracted more and more attention from the world. It is internationally recognized as a “never-failing” industry. In the economically developed countries such as the United States, Canada, Japan, Finland and Sweden, the papermaking industry has become one of the top ten pillar manufacturing industries of the national economy. The characteristics of modern paper industry are different from the general consumer industry of daily necessities. Instead, it is a basic raw material industry featuring technology, capital, resources, energy intensive, remarkable scale efficiency, continuous and efficient production. Of the total products, more than 80% are used as the means of production in the press, publishing, printing, commodity packaging and other industrial fields, and less than 20% are used for people’s direct consumption. The papermaking industry is closely related to forestry, agriculture, machinery manufacturing, chemical industry, thermoelectricity, transportation, environmental protection and other industries, which plays a certain role in stimulating the economy of the upstream and downstream industries. Nowadays, countries in the world have taken the production and consumption level of paper and cardboard as one of the important symbols to measure a country’s level of modernization and civilization. The product range of the industry is: pulp, machine paper and paperboard, processing paper, handmade paper, etc.
6. Vacuum pumps are used in chemical fiber industry
Since the reform and opening up more than 20 years ago, China’s chemical fiber industry has developed rapidly. Chemical fiber has become the most important raw material of the textile industry, and chemical fiber industry has rapidly become one of the pillar industries of the textile industry
