The chemical industry must be reborn in the process of transforming development

In the economic field of our country, we will set off a powerful mode of transformation and development, adjust the industrial structure, and eliminate the whirlwind of backward and excess production capacity. From the public opinion level to the operational level, from the promulgation of documents to the implementation of strong forces, “the rain will be overwhelming Building" trend.
As an important industry of the national economy and a major energy-consuming and carbon-consuming emitter, chemical industry will face severe challenges in the post-financial crisis era. Over the past 30 years of reform and opening up, China’s chemical industry has made considerable progress and made important contributions to the development of the national economy and the improvement of people’s living standards. The output of some products is at the forefront of the world, and some new technologies have achieved breakthroughs and are at the international advanced level. But on the whole, China can only be counted as a big chemical country, not a chemical power. In most high-tech fields, there is a big gap between China and developed countries. Every year we spend a lot of foreign exchange to purchase foreign chemical products; under the policy of maintaining growth, the problem of overcapacity of many products continues to increase; the highly monopolized oil management system restricts The development of chemical companies and the technological advances in the chemical industry; some lagging companies and managers with indifferent awareness of energy conservation and environmental protection, from time to time to create environmental pollution incidents, chemical industry became synonymous with pollution, so that the chemical industry contained dust; chemical industry is also this One of the industries that suffered the most from the international financial crisis. The chemical industry has come to the point where it must speed up the transformation of development methods and adjust the industrial structure. If we continue to follow the old road of extensive development, the development of the chemical industry will be unsustainable and the gap with the developed countries will further widen.
First, the resource environment has become a bottleneck. China's per capita resources are relatively poor, with per capita oil and gas accounting for only 10% of the world average, and per capita water resources accounting for only 20% of the world average. China's energy consumption per 10,000 yuan GDP is 3-4 times the world average. From the point of view of the international market, as long as China's demand for raw materials, it will sharply increase prices, so that China's profits in the bottom curve of the smile of enterprises can not afford. From the point of view of the environment, dust storms in China are raging, rivers and rivers are becoming more and more polluted, extreme weather is becoming more frequent, and the ecological environment is becoming more and more fragile. Nature has issued a red warning to humans. Resources and the environment will become the bottleneck for the development of the chemical industry.
The second is that excess capacity has caused disasters. According to a report released by the National Petrochemical Association, the relative overcapacity of chemical products such as methanol, urea and PVC in China will not be resolved but will be further aggravated. Most chemical products such as chemical fertilizers, pesticides, and rubber products have relatively surplus production capacity and need to balance the demand in the international market. However, the investment impulse is still high. In the case of shrinking exports, surplus products will inevitably appear low-price competition and kill each other, leading to the outcome of disasters.
The third is barriers to product exports. In the post-financial crisis era, the United States, Britain and other Western countries put forward the slogan of "re-industrialization." The government has invested heavily in helping the manufacturing industry to ease the pressure on employment in the country. The “reindustrialization” of Western countries has led to the rise of trade protectionism. Trade disputes caused by China have frequently occurred. Export trades, including chemical industry, will encounter more severe trade barriers. The future of chemical products exports is not optimistic.
Fourth, multinational companies occupy space. Multinational corporations have increased the competition for layout in the Chinese chemical market. The world-renowned chemical giants have seized the spot in China and expanded their production capacity, which will inevitably squeeze the development space of China's chemical companies and bring serious challenges to China's chemical companies.
Chinese ancient poetry reads: "The mountain is heavy and the water is in doubt, and the village is full of flowers." In the post-financial crisis era, it not only brought serious challenges to the chemical industry, but also changed the development mode for the chemical industry and brought about a development opportunity to adjust the industrial structure.
First, China has become the world's chemical industry. The rapid development of China's economy has created a good environment for the development of chemical companies. There are more and more multinational chemical companies seeking cooperation with China's chemical companies and developing in China. Not only multinational companies in developed countries but also large enterprises in developing countries have become a hot spot and a wasteland for chemical industry in the world. For China's chemical companies, it is a severe challenge and also an opportunity for development. Practice has proved that there is no way out of self-closedness through retreats and lock-in, and only in learning, communication, and cooperation can they complement each other, improve themselves, and accelerate the development of chemical companies in China. China's chemical industry should open its mind and expand its opening up. On the one hand, it should actively explore international mergers and acquisitions to expand its development space. On the other hand, it actively introduces global best practices and the best talents to make full use of both domestic and foreign resources and two markets to inject vitality into China's chemical industry.
The second is to play an industry advantage in developing a low-carbon economy. Low-carbon economy has become the major trend and engine of world economic development. Britain, the United States and other developed countries have seized the opportunity. The change from carbon resources to carbon damage is mainly achieved through the process of chemical change. Therefore, the solution of the global climate crisis caused by the high carbon caused by the solution of the bell must be the responsibility of the chemical industry. The chemical industry is duty-bound and indispensable. The chemical industry will play an industry advantage in providing specialized technologies for carbon emission reduction, expanding the carbon utilization market, and exploring carbon capture channels. For example, technological advances in chemical products will play a role in energy conservation and consumption reduction in the fields of automobiles, construction, and airplanes. Some chemical companies in China have mastered the technology of carbon capture, separation and purification. The technology in the field of comprehensive utilization of carbon dioxide is not much different from the world advanced level. Some of these technological achievements have been popularized and applied, and have achieved good environmental and economic benefits. China's chemical companies must comply with the trend of the times, implement the scientific concept of development, accelerate the transformation of development methods, and take the low-carbon economy as the direction, and increase the research, development, and production of materials science, life sciences, and environmental sciences. We must actively eliminate backward and excess production capacity, move early, and take the initiative; early actions, early benefits; and inaction, may be eliminated by the times.
The third is to expand Xintiandi in the hopeful field. On January 31 this year, the Central Government issued the 7th document on “Agriculture, Rural Areas and Farmers” in the 7th century - “Several Opinions on Strengthening the Balance of Urban and Rural Development to Further Consolidate the Foundations of Agricultural and Rural Development”, which symbolized agriculture and rural areas. Development not only increases the weight of injections, but also pays more attention to the improvement of quality. The field of development is not limited to the fields of rural hope, but also concerns the consumption of peasants' living, agricultural machinery, and household appliances. The modernization of the 800 million peasants' life in China and the rapid advancement of urbanization will become China’s continuing huge domestic demand market, and it will also open up new horizons for the development of chemical companies. It not only injects vitality into traditional chemical products such as pesticides, fertilizers, agricultural films, but also brings development space to new products such as engineering plastics, building materials, and low-carbon products. The majority of chemical companies will make a difference in advancing China's "three rural" development process.
Choosing the right thing is more important than doing it right. In the critical period when the future is concerned, the chemical industry needs phoenix renouncement and rejuvenation.

The Car Alternator is the main power supply which function is to provide electricity to all the power equipment (except Starter) when the engine is in normal operation (at the same time as idle) and charge the battery at the same time.

Alternator usually consists of four parts: rotor, stator, rectifier and end cap.

Automotive engines are widely used in industrial and agricultural production, national defense, science and technology, daily life and so on.

At present, the use of AC generators widely used in automobiles should pay attention to the following points:

1. The appearance of the generator often clean fouling and dust, clean and well ventilated.

2. Check the fastening of generator and fasteners, fasten the screws in time.

3. The tension of the driving belt should be suitable. Too loose, easy to slip, resulting in insufficient power generation; too tight, easily damaged belts and generator bearings.

4. When installing the battery, do not install the wrong, usually first install the positive line, do not install the wire, otherwise it will easily burn out the diode.

5. When the IC regulator is used, the ignition switch should be switched off immediately when the engine is not working.

6. We never allow the use of "scraping fire" method to test whether power.

7. The generator has the power failure, to promptly eliminate, otherwise it will cause more serious problems.
