Experts from all walks of life feel the pulse for the development direction of the plastic industry

at the second plastic industry development seminar held in Taizhou City, Zhejiang Province not long ago, they interviewed the head of the plastic industry organization and relevant experts and scholars on the development prospects, production, technology, environmental protection and other issues of the plastic industry

develop the plastic industry around the world

Dai Zhongyao, Secretary General of China Plastic Machinery Industry Association, attaches great importance to the issue of plastic enterprises going global. He said that plastic machinery is an important part of industrial consumption and an industrial sector supported by the state. Plastic machinery is a necessary equipment for plastic processing industry and plastic products industry, and the development of plastic machinery also depends on the development of plastic products and raw material processing industry. There is a causal relationship between plastic machinery and raw materials and plastic products used in plastic processing, which are interdependent

the State encourages enterprises to develop abroad, and has issued a series of preferential policies for this purpose. China Plastics Machinery Industry Association will organize enterprises that are ready to develop abroad next year to do some work for them. Enterprises in plastic machinery and plastic products industries have great prospects for development abroad, which is very beneficial to the development of China's plastic industry. It is advisable to take a long view of the scenery and expand the vision of the development of the plastic industry to foreign countries

China Plastics Machinery Industry Association has certain ties with foreign countries, such as maintaining a close relationship with the Australian government. The local government has established some development zones near Sydney, and some projects want us to develop them. Of course, they also have some comments on our association. In the first half of next year, our association will continue to organize some domestic enterprises to visit Australia

the development momentum of engineering plastics is good.

ZHENG Kai, Secretary General of the plastic industry association of the Chinese industry immediately shut down the oil pump and oil delivery valve, expounded his views on the development of engineering plastics after China's entry into WTO. He said that in recent years, China's engineering plastics industry has developed very fast, maintaining a rate of more than 20% every year. The state attaches great importance to engineering plastics and has formulated a series of preferential policies to support the development of engineering plastics. Therefore, in this environment, China's engineering plastics industry has maintained a good momentum of development

however, China's engineering plastics started relatively late and is only in the development period at present. Moreover, most of China's engineering plastics enterprises have been developed by small and medium-sized enterprises and scientific research institutes, and there are certain problems. These problems have a strong regional nature, especially that most enterprises implement empirical management. In this case, engineering plastics enterprises should pay attention to the following aspects to meet the challenges after China's entry into WTO: first, engineering plastics enterprises should formulate a reasonable strategic development plan, which is very important for enterprises to achieve half the result with twice the effort, and is the key to maintain their competitive advantages. Without strategic goals, many enterprises compete in a very limited range. Due to the narrow scope of the market, it leads to excess production capacity, a relatively single variety, and a decline in profit margins. Therefore, enterprises must formulate reasonable strategic goals

second, as an enterprise, it should establish an innovation mechanism, which is also a mechanism to improve work efficiency, and condense the core competitiveness of the enterprise. Innovation is not only an invention, but also a means to improve efficiency. Core competitiveness has four characteristics: can't steal, can't buy, can't open, can't take away. The core competitiveness is not as easy to copy as the CD-ROM, and it is unique to the enterprise. The three elements of management, resources and technology are complementary and inseparable, and personal skills do not constitute the core competitiveness of the enterprise. Now the available resources are equal and open, and every enterprise can get what it needs. The key is that the survival state of an enterprise is different with its integration ability. The key is to continuously reduce the manufacturing and sales costs and improve the economic benefits of enterprises through reasonable means. From this point of view, Taizhou Plastic enterprises have their own uniqueness: the enterprise is small in scale, but the product price is low, the cost should be reduced as much as possible, and the late development advantage should be made good use of, that is, taking advantage of the characteristics of low labor price, low sales cost, low market development cost, and their own local research and development ability, so they can sell their products all over the country. At the same time, Taizhou Plastic enterprises have strong supporting capacity, including enterprises that produce molds and sell raw materials, as well as enterprises that provide accessories. Therefore, the development of Taizhou Plastic industry is a model worthy of reference

third, enterprises should establish new marketing concepts. Production orientation is to seek to meet the existing needs and increase the sales of counterpart products, while market orientation focuses on the potential market and strengthens stimulation and guidance according to the potential market needs. But at present, some enterprises only pay attention to the output of material products, and do not create a living space for enterprises. Therefore, the reputation of the industry and the development of brands should attract the attention of enterprises. After joining the WTO, we are facing the rules of the game of the world trade organization, which must be implemented in accordance with international practices

in addition, the small scale of China's plastic enterprises is a major problem after China's entry into WTO. Therefore, industry associations should do the work of integration, and enterprises should work together as aircraft carriers of the industry to improve the ability to resist risks, otherwise they will lose competitiveness and a large number of small enterprises will collapse. While conducting horizontal strategic alliances to resist external competition, enterprises should also pay attention to the national policy guidance and use policies to promote their own development

it is of great significance to develop degradable plastics

Tang saizhen, Secretary General of the degradable plastics special committee of China Plastics Association, believes that environmental protection and sustainable development have become the focus and urgent task of social attention in the 21st century. At present, plastic, as a new material, with its excellent comprehensive performance, low price, easy molding and processing, has become the first person engaged in the industrialization of aerogel gel in China. It has widely entered all fields of the national economy and all aspects of people's life, and has been more and more widely used. While providing an effective development platform for human and technological progress, we have to admit that a large amount of plastic waste is seriously endangering the environment and human sustainable development. According to statistics, in 2001, the output of plastic raw materials in China was 12.0385 million tons, and the import volume was 14.26 million tons. All state-owned and non-state-owned independent accounting industrial enterprises in the plastic processing industry with an annual sales revenue of more than 5million yuan produced 11.835 million tons of plastic products. Together with small and medium-sized enterprises, it is estimated that the total output of plastic products in the country reached more than 20million tons, and disposable plastic products that are difficult to be recycled accounted for 20%, This alone generated 4million tons of plastic waste. The resulting negative impact of the plastic industry on the environment has become increasingly serious, and has been compared to "white pollution" and criticized

according to China's solid waste pollution prevention and control law, the plastic industry should focus on the analysis of the role of environmentally degradable plastics in protecting the environment and implementing sustainable development strategies from the perspectives of reduction, recycling, harmlessness, resource supplementation and substitution, and LCA in the whole life cycle of products, so as to explore ways to save resources and reduce pollution

caco3/polyolefin composite is beneficial to environmental protection

Wang Xichen, Professor of Polymer Materials Department of Beijing University of technology and technology, said that with the continuous development of technology and theory, CaCO3 has changed from a simple filler to a new type of functional filler. Filling a large amount of CaCO3 will not significantly reduce the performance of products, and some properties will be greatly enhanced. At the same time, under the guidance of inorganic rigid particle toughening theory and interface induction theory, using new surface activation technology and blending technology, CaCO3/polyolefin composites can be filled with up to 60% - 70% (by mass) CaCO3 under the condition of ensuring service performance, which can greatly reduce the amount of resin, save oil resources and reduce product costs

common CaCO3/polyolefin composite plastic products, the matrix resin is mainly polypropylene, which is very easy to degrade under such a high CaCO3 filling amount. The main resin of individual products is polyethylene, which can be made into degradable plastics by adding a small amount of photodegradation masterbatch, so these products are environmental friendly products. Some easily recycled products, such as disposable wooden chopsticks and synthetic coated paper, can be recycled in a short time. For products that are not easy to be recycled, foreign incineration can be adopted to recover heat energy. Plastic products filled with CaCO3 more than 30% (by mass) are easy to burn fully and will not explode due to bonding to the furnace wall. Therefore, as an ideal environmental protection product, CaCO3/polyolefin composite plastic products have been more and more recognized by people, and will play a greater role in the treatment of "white pollution"

in situ composite technology has broad prospects

Zhao Anchi, chairman of the special committee of modified plastics of China Plastics Association and professor of Polymer Research Institute of the Department of chemical engineering of Tsinghua University, believes that in situ composite refers to that the reinforcing phase is not formed before resin processing, such as glass fiber, carbon fiber, aramid fiber, etc., but formed in situ during processing. The new technology of in-situ composite has changed the traditional concepts of filling, reinforcement and blending modification, and is considered to be one of the major advances in plastic modification technology in the 20th century. With the continuous deepening of research work, the gradual commercialization of new varieties of in-situ composites, the rapid expansion of production scale, the increasing expansion of application fields and the decline in the price of modified materials, in-situ composite technology shows strong vitality in plastic modification. It can not only be used as a good means of modification, but also an important way to develop plastic varieties. It will also promote the competition of new materials and open up a broader prospect for the application of modified plastics in new technology and high-tech fields

inorganic powders are used more and more widely.

Professor Yu Jian, director of the Polymer Research Institute of the Department of chemical engineering of Tsinghua University, said that with the progress of inorganic powder processing technology and polymer material composite technology, inorganic powders used in polymer materials have changed from traditional fillers to high-performance modifiers or functional additives, and their use range is becoming wider and wider. However, the current technology is far from being able to maximize the application value of each inorganic powder. We put forward the basic methods and principles of dividing various microscopic phase interfaces in polymer/inorganic powder composite system by using the interaction relationship between constituent substances in the material system, and various effective methods of designing and regulating the microscopic phase interfaces at different levels, establishing various composite technologies and developing a series of high-performance composites. This technology can greatly reduce the cost of materials while achieving high-performance or multifunctional molecular materials, and is conducive to promoting the development and application of this technology

additives promote the functionalization of materials

Professor Chen Yu, vice president of Beijing Research Institute of chemical industry, said that as we all know, polyolefin is cheap, excellent in performance and easy to process, and has become one of the largest polymer materials in China with the least amount of care, let alone keeping a low profile. The film products made by it are increasingly used in agriculture, industry and daily life as covering, packaging, isolation and other materials. Packaging and agriculture are two major application areas. However, ordinary polyolefin films can no longer meet the special application needs of these two fields
