In recent years, the agricultural plastics industry, known as the "Chaoyang Industry," has developed rapidly. Agricultural film, plastic film, shade nets, insect nets, livestock and poultry warmers, forage grass, rice seedlings, vegetable cling film, and plastic seedlings The use of floppy disks, plug-holes, and plastic water-saving equipment has become more and more widely used in agricultural production, and has made important contributions to the development of China's agriculture to a new level and into a new phase. Today, China has become the country with the largest area of ​​horticultural facilities cultivation and mulching.
The functions and properties of agricultural plastics are mostly obtained by adding functional auxiliaries. In the case of agricultural films, the use of anti-aging agents (light, heat stabilizers), dripping agents, heat-insulating agents, anti-fog agents, antiperspirants, dust-reducing agents and other additives can increase the use of agricultural films. Transparent and translucent; increase the temperature of the greenhouse; prevent drip and prevent fog; improve the efficiency of crop photosynthesis in the greenhouse, and the effect of anti-dust and dust prevention. As different types of agricultural plastic products require the addition of different types of additives, the demand for the types and quantities of agricultural plastic additives in the domestic market is increasing. The annual growth rate of demand is more than 30%. In 1999, the amount of agricultural film used in China reached more than 600,000 tons, of which the amount of polyethylene film with anti-dropping and anti-aging functions was 150,000 tons, and 1500 tons of anti-dropping agents were used. Anti-aging agents (including light stabilizers) And antioxidants) 800 tons. As domestic production cannot meet demand, anti-aging agents, anti-fogging agents, and anti-fogging agents need to be imported from abroad. Some experts expect the domestic market to demand 3,000 to 3,750 tons of anti-fog drops and 1,000 to 2,000 tons of anti-aging agents this year. By 2010, the demand for various auxiliaries in the domestic market will double on the basis of this year. The market prospects for agricultural plastic auxiliaries are promising, and there are many opportunities for related companies.
Although China's agricultural plastics additives market is very large, but due to the late start of research and development of agricultural plastic additives in China, the foundation is thin, the technical level is relatively backward, the domestic high-performance additives are seriously insufficient, and a large number of foreign additives are needed to meet the demand each year. . Some experts have analyzed that the main reason for this phenomenon is: China's systematic research on agricultural plastics additives is not enough. Agricultural plastics additives industry is a new industry. For a long time, the research and development of agricultural plastics additives only rely on one or two research units to carry out, it is difficult to meet the needs of production enterprises. Due to the lack of support from scientific research, small workshop-type manufacturers account for a large proportion, and they have a single variety, similar performance, and insufficient quantity scale. In addition, due to the lack of reliable product quality testing methods, product quality performance is unstable. Affected the credibility of the company.
At present, the development and application of new agricultural plastic additives in China lags behind the international advanced level. In recent years, the light stabilizer BW-10LD and antioxidant PL developed by the Beijing Chemical Research Institute
The anti-aging system composed of 10 has achieved a very good synergistic effect on the polyethylene agricultural film. The life of the anti-aging film produced using this system (thickness 0.1mm) can reach 18 months, and it is already on agricultural plastic products. Use it heavily. However, the current continuous service life of foreign films is generally 3 to 4 years, some up to 5 to 8 years, and the continuous service life of domestic weather-resistant functional films is generally only about 1.5 years, despite the film thickness, There are different reasons such as the amount of additives added and the mode of cultivation, but overall, there is a single product in the domestic anti-aging additives and there is a big gap with foreign countries.
Experts pointed out that the development of China's agricultural plastics industry is stuck on functional additives and special resins. Due to the serious shortage of domestic high-performance additives, many foreign manufacturers have rushed to China, the world's largest market for agricultural plastic additives. They entered high prices and low prices, dumped prices, and competed with domestic companies. At the same time, special resins for agricultural plastic products have not attracted enough attention from companies. Due to factors such as cost, class output, total usage, and device capability, it is difficult to meet the demand, while the high prices of similar foreign products are difficult to meet actual needs. Therefore, in order to promote the development, production and promotion of new agricultural plastic additives in China, to improve the technical level of China's agricultural plastic additives and to realize the modernization of agriculture, a research and development center for integrated agricultural plastics and functional additives should be established as soon as possible. The mechanism and application of agricultural plastics and additives, quality inspection, accident analysis, information dissemination and exchange and other work.
Experts stressed that reviewing the research on agricultural plastic additives in foreign countries has a strong advantage in terms of single varieties, but there are obvious drawbacks. That is, when the products are used in agricultural plastic products, various additives are mutually used. The synergy effect and the entire additive system have not been studied adequately for the performance of agricultural plastic products, which severely restricts the promotion of the product. The characteristics of agricultural production require that the additives produced and developed meet the required functions and require not only a negative impact on the functions of other additives, but also must be adapted to the adverse natural conditions and the need for environmental protection. This must be required. Comprehensive comprehensive inspection of agricultural plastic additives. At present, the research work of agricultural additives in various countries around the world is basically individualized, such as the world-famous Swiss company C ib a refinement company, the United States CYTEC company, Germany's Klein company, etc., only produce anti-aging agent; ICI and Japan's Toho Chemical Co., Ltd. only produce liquid drops, etc., and there is no institution that systematically studies the agricultural plastics auxiliary system. Therefore, this situation is not conducive to the promotion and application of additives in agriculture, and it is not conducive to the development of new varieties of agricultural plastic additives. In order to promote the development of agricultural plastics additives in the world, it is also urgent to set up a specialized comprehensive research center for agricultural plastics and functional additives.
Zhang Zhenhe, the secretary general and researcher of the China Association of Agricultural Plastics Application Technology, believes that the establishment of a research center for agricultural plastics and functional additives is not only an objective requirement for the healthy development of the agricultural plastics auxiliary industry and the agricultural plastics industry, but also a need for agricultural development. There should be such a specialized research institution. Now, the agricultural plastics industry has developed rapidly. The annual amount of plastics has reached 2 million tons. It is estimated that by 2010, the amount of plastics will reach about 4 million tons. At present, over 85% of agricultural films in China are ordinary membranes, and the functional research and development of plastic membranes Did not mention the schedule. Compared with foreign countries, China's anti-aging of functional films must be more than one year apart, and the functional auxiliaries have a single dosage form (mainly internal additive type), which is far from meeting the needs of agricultural plastics development. Therefore, it is of great significance to seriously organize and develop new technologies and new products for agricultural plastics. If there is such a center, the concentration of a group of experts and talents, and the development and application of agricultural plastics as a systematic project, will greatly promote the technical progress of the agricultural plastics industry.
Liao Authentic, chairman of China Plastics Processing Industry Association and director of the National Plastic Products Standardization Technical Committee, believes that the establishment of an agricultural plastics center is very important and necessary, and has been appealed many times before. Of course, what kind of form the center appears in is worth exploring and studying. Because the production, use, and management of agricultural plastic products involves chemical, light, and agricultural sectors, as well as associations and societies of agricultural plastics technology societies and agricultural film special committees affiliated to these different sectors, it is necessary to establish agricultural plastics. Center, then who will take the lead? What kind of combination? How to solve the problem? If these are not implemented, I am afraid that even the best ideas are difficult to achieve.
Chen Yu, deputy dean of the Beijing Chemical Research Institute and director of the Fine Chemicals Research Institute, believes that the current mission and goal of the “center†for agricultural plastics and functional additives research in this country should be: in the field of existing agricultural plastics additives in the country , More systematic and comprehensive research on related issues, and establish a leading position; gradually improve the testing and analysis methods of agricultural additives, and initially form a standardized approach to accident analysis and resolution. The topics to be studied include: high-performance polymeric light stabilizers (including antioxidants), long-term anti-aging aid systems, heat-insulating agents, and light-converting agents.
Numerous experts and scholars have been deeply interested in the sustainable and efficient development of China's agriculture. Indeed, the establishment of a research center for agricultural plastics and functional auxiliaries is a matter of national economic and agricultural development. It urgently needs the strong support and coordination of policies from the relevant national authorities to promote the establishment of an agricultural plastics center as soon as possible.
