The development of chlor-alkali enterprises is inseparable from the dependence on resources and energy. At the same time, as a branch of the basic chemical industry, the basic chemical raw material products of the chlor-alkali industry also account for a large part of the product value. With the increase of economic development in the eastern part of the country, the cost of local human resources has increased, and the transformation of cities in the eastern region from industrialized to commercialized cities has caused the chlor-alkali enterprises to be limited in their development in the east. In this way, the chlor-alkali industry in our country is focused on and shows a trend toward the west.
The reserves of mineral resources in the western region of China are considerable. The hydropower resources are very abundant and the potential for development is huge. It is an important strategic area and has good prospects for development. The strategic decision of the development of the western region of the country will have a profound impact on the economic development of western China in the period to come, and will also bring about good opportunities and new challenges in the new economic environment for the healthy and sustainable development of the chlor-alkali industry in the region.
However, the development of the chlor-alkali industry in the west of China has not been imaginatively optimistic. Among the many western chlor-alkali enterprises, there are some small-scale enterprises with high energy consumption. In production, many companies have also exposed the outdated equipment and raw materials. The backward route, high energy consumption, serious pollution, small scale of production, low production, poor economic returns, and lack of the disadvantage of international competitiveness have greatly affected the development of chlor-alkali enterprises in the west.
Therefore, western chlor-alkali enterprises need to use new concepts and new methods to manage their business operations and explore the potential energy of the western chlor-alkali industry.
First of all, it is necessary to increase the construction of circular economy, and not to waste industrial resources and to destroy the environment. Sustainable industrial development is not just an issue of environmental issues and economic growth, but also a social issue. Any industrial development must not be at the expense of environmental destruction and waste of resources. The sustainable development of the chlor-alkali industry must also follow this basic principle, vigorously adopt advanced advanced technologies, and eliminate or convert traditional backward technologies that have high energy consumption, heavy pollution, and poor efficiency. , Save energy and reduce consumption, increase the research and development of “green†chlor-alkali products, and realize the construction of circular economy in the production process.
Second, do a good job of joint development of salt and alkali and establish a large-scale chemical joint venture. Salt and alkali production are the two pillars of chemical industry. Many salt companies in Europe and America are joint companies of salt and alkali, such as Akzo Chemical Salt in the Netherlands, Kafolo in Italy, and Hook in West Germany. In addition to vigorously developing chlor-alkali products, the chlor-alkali industry and salt chemical industry can also use electrolysis to develop by-product hydrogen from the sodium chlorate industry, and then produce chlorine dioxide and various hydrogen products with high value-added applications. At present, one of the key developments in China's salinization industry is the development of sodium chloride in the deep processing of sodium metal production, the use of by-product chlorine to produce a variety of chlorine products, especially to ease the dramatic increase in PVC production capacity, resulting in shortage of chlorine and the original excess The caustic soda market is worsening.
Third, the use of abundant natural resources, the development of diversified characteristics of raw materials, chlorine products, in order to enhance market competitiveness. Chengdu-Chongqing area uses abundant natural gas to develop natural gas to make acetylene. Changshou Chemical Plant replaces calcium carbide with natural gas acetylene to produce neoprene, which can greatly reduce production costs and eliminate serious pollution of calcium carbide slurry, dust and wastewater. The Guangxi Zhuang Autonomous Region is rich in ilmenite resources. The Nanning Chemical Industry Group Corporation can vigorously develop the chlorination method of rutile titanium dioxide, do a good job in the industrialization of titanium dioxide in the chlorination process, and then develop the nanomaterial Ti02, and gradually develop into the chlorination method of titanium dioxide. Production base.
Finally, we will increase the research and development of advanced and applicable high-tech and quickly eliminate backward technology and equipment. In the western part of China, advanced metal anode technology (modified diaphragm, expanded anode, active cathode) electrolysis equipment or electrolysis equipment representing the world's most advanced ion-exchange membrane technology should be used to replace or convert the old production process. At the same time, when we insist on reforming, expanding, and constructing new chlor-alkali electrolyzers, we must use advanced ion-membrane electrolyzers to eliminate or reduce the harm to humans and the environment caused by heavy metals such as lead and asbestos, and at the same time save energy and increase consumption. benefit.
Only by effectively combining the development of the western region and developing a sustainable development path suitable for the development of chlor-alkali enterprises, can the western chlor-alkali industry be continuously expanded, and the comprehensive strength of China's chlor-alkali industry will continue to grow during the process of chloralkali expansion.

Aluminum anodization is an electrochemical process that enhances the strength, durability, and appearance of aluminum. When aluminum is oxidized, super-strong oxide (anodic) layers [grow" on the surface of the metal. These new layers are highly resistant to wear and corrosion.
The exacting part to part consistency achieved with our unique anodizing system cannot be obtained with conventional hoist line systems. Conventional anodizing systems present parts with varied coating thicknesses and voids formed due to air pocketing.
A consistent uniform 6 µm anodic film thicknesses will protect certain drug formulations and the canister from degradation. Heavier film thicknesses of up to 12µm can be provided to meet your more demanding application.
