Inorganic fine chemicals belong to the category of fine chemicals, but they differ from fine chemicals. It includes pharmaceuticals, veterinary drugs, pesticides, dyes, pigments, coatings, light-sensitive materials, magnetic recording materials, printing inks, flavors and fragrances, chemical reagents, catalysts, aerosols, adhesives, surfactants, detergents, paper chemicals, Automotive chemicals, leather chemicals, oil field chemicals, electronic chemicals, information chemicals, feed, food, electroplating, water treatment agents, mineral processing agents, refrigerants, industrial cleaning agents, etc. , also includes various additives (such as textile auxiliaries, printing and dyeing auxiliaries, plastic auxiliaries, rubber auxiliaries, polymer additives, pesticide auxiliaries, oil additives, etc.), functional resins, and biochemical products. Various types of intermediates, etc. Inorganic fine chemicals are rarely supplied directly to end users as products.
Inorganic fine chemicals belong to the high-tech category. Although it does not directly serve the national economy and people's lives and promotes progress in various fields of national economy, national defense, and scientific research, it can change the performance of downstream products, improve their quality, increase the added value of products, and reduce their production costs.
The characteristics of traditional inorganic salt products are many varieties, large output, wide use, and wide coverage. Inorganic fine chemical products require more specialization, functionalization, serialization, and refinement. Not only that, the application of inorganic fine chemical products in traditional products is also changing its original image. Such as ultra-fine calcium carbonate in the plastics, rubber industry applications, play a dual role in filling, reinforcing, reducing the production cost of the product, but also enhance the function of the product, improve the quality of the product, increase the added value of the product. All these indicate that inorganic fine chemical products are no longer just “monosodium glutamate†but have become indispensable main raw materials for various industries. It can be said that the development of high-tech can not be separated from inorganic fine chemical products.
Since the reform and opening up, with the acceleration of the modernization of the national economy, the domestic inorganic fine chemical industry has achieved an unprecedented rapid development, and the role of inorganic fine chemical products has become increasingly prominent. At present, there are more than 1,000 inorganic fine chemical production enterprises in China. The production capacity accounts for about 10% of the total production capacity of inorganic salt products. There are more than 700 kinds of product varieties and the annual production value is about 30 billion yuan. The refined rate of inorganic salt products has reached about 35%. Some inorganic fine chemicals not only meet domestic needs, but also are important foreign exchange products. A considerable number of inorganic fine chemical products occupy an important position in the international market. The development of inorganic fine chemicals has promoted and stimulated the development of China's inorganic salt industry. Specifically embodied in the following aspects:
(1) The product structure has been initially improved, and new varieties have increased rapidly.
In addition to the significant increase in the output of inorganic fine chemicals, the variety and grade of products have also undergone great changes, which have met the needs of domestic and foreign markets to a large extent. Such as paper industry, special calcium carbonate, sodium chlorate, low iron sulfate, polyaluminum sulfate for water treatment, polyferric sulfate, aluminum chloride, chlorine dioxide, high purity hydrogen peroxide for electronic matching, lithium hexafluorophosphate , lithium cobaltate, lithium manganate, lithium nickelate, high purity barium carbonate, barium carbonate, lead oxide, lead silicate, potassium carbonate, zinc oxide, high purity iron oxide, spherical high activity nickel hydroxide, and fine ceramics Supported zirconia, boron carbide, boron nitride, cobalt oxide, antimony oxide, high-purity nano-alumina, silica, and a large number of products for food, feed, medicine, pesticides, dyes and other fine chemicals, become In recent years, China's inorganic salt industry has developed a new hot spot. (2) The corporate organizational structure has undergone major changes.
Firstly, joint ventures and cooperative enterprises have developed rapidly. A large number of well-known foreign companies have been involved in the production of inorganic fine chemical products in China, such as Rhone-Poulenc in France, Dead Sea Australia in Israel, Degussa in Germany, Simeon in Italy, and Oxytech in the United States. , Germany Lurgi, South Korea Unid, Japan's Mitsubishi Gas Chemical Company, the United States Cabot Corporation, the United States DuPont, the British Biosi Group, the French Air Liquide Company, are well-known international companies. The Chinese companies that cooperate with them are also mostly domestic backbone enterprises. Most of the joint ventures are controlled by foreign parties and have a high level of technology and equipment. This shows that after China's accession to the WTO, the speed at which international large companies seize the Chinese market is accelerating. The second is the rapid development of township and private enterprises. Since the reform and opening up, local villages and towns and individual operators have built a large number of inorganic salt production plants. Through the development in recent years, a group of enterprises with a high level of refinement, considerable scale, and strong competitiveness have grown up. Such as Sichuan Longxi Group, Guangdong Zhongcheng Group, Jiangsu Chengxing Group, Sichuan Oscar Chemical Co., Ltd., Guizhou Jianfeng Chemical Co., Ltd. and so on. These enterprises have large scales, many varieties, and high grades of products. Many state-owned enterprises cannot compare them.
(3) The production level continues to increase.
In recent years, the production level and specialization level of China's inorganic fine chemical production enterprises have been continuously improved, and the scale of the equipment has continuously expanded, basically meeting the needs of domestic consumption. In particular, the scale, production, and sales of food and feed additives, water treatment agents, and electronic chemical manufacturers have all rapidly increased. The total output of inorganic food additives reached more than 500,000 tons, the sales income was more than 2 billion yuan, the output of inorganic feed additives was about 1.3 million tons, the sales revenue was 1.5 billion to 2 billion yuan, the output of water treatment agents was 600,000 tons, and the sales revenue was 6 100 million yuan to 800 million yuan. There are hundreds of varieties of products for the electronics industry, of which the production of barium salt and barium salt ranks first in the world, and the annual export volume accounts for about 50% of the world's total trade volume. Inorganic fine chemicals such as manganese, tungsten, molybdenum, zirconium, tin, antimony, and rare earths also play a decisive role in world trade.
At the same time, the technical level of China's inorganic fine chemicals has also greatly improved. The main performances are as follows: First, the level of independent technology has been continuously improved; second, the introduction of technology has led to the improvement of the technological level of related industries.
