According to data from the China Petroleum and Chemical Industry Association, in the first half of this year, synthetic resin, as an important branch of the petrochemical industry chain, continued to maintain a rapid growth momentum, with output and output growth exceeding 15%. This year's domestic synthetic resin consumption is expected to increase. It will reach 33.65 million tons, an increase of 8.5% over the previous year, and production is expected to increase by more than 15%. At the same time, the external dependence of China's synthetic resin is very high, especially the situation where special materials and high-grade materials rely on imports.
Many types of resins need to be imported. The time for the truly large-scale development of China's synthetic resin industry is relatively short. Technology is often introduced from abroad, and it is constrained by funds and other reasons. At the time of introduction, it is often only possible to introduce some brands, most of which are widely used. Resin grade. Although domestic enterprises digested and absorbed most of the resin products introduced by domestic petrochemical companies, they were still the “oldest†type, and most of the special materials and advanced engineering plastics, such as polycarbonates, polyoxymethylenes, polyamides, etc., whose usage increased rapidly, were developed. less.
At present, China's synthetic resin industry has an external dependence of up to 55%. According to statistics, China's import of synthetic resin was 21.31 million tons last year, of which nearly half were engineering plastics and special resins, and imports increased rapidly. Before 2004, imports increased by about 1.8 million tons per year, while imports in 2004 were higher than in the previous year. The increase was 2.2 million tons, which was mainly driven by the increase in imports of special materials and engineering plastics. Due to the high dependence on foreign countries, although China is the world's largest importer of synthetic resins, it cannot independently set prices, especially for those resin varieties that China cannot produce on its own, all of which are internationally priced, and the current international crude oil prices remain high. Next, the price of these resin products has also risen, while domestic users can only passively accept.
Leading in the R&D of some products The good news is that some companies and institutes have broken through the technological blockade of foreign companies and achieved breakthroughs in some special engineering plastics.
After many years of experiments, Jilin University independently researched and developed the special polymer PEEK (polyether ether ketone), making China the second country that can produce this special material after Britain. PEEK is a new semi-crystalline aromatic thermoplastic engineering plastic that can replace traditional materials such as metals and ceramics in many special fields. It is one of the most popular high-performance engineering plastics in the world today. The successful development of this product broke the monopoly of Victrex in the United Kingdom.
In the industrialization of polyphenylene sulfide (PPS), where consumption has soared, China has also made remarkable achievements. Sichuan Deyang Technology Co., Ltd. relies on independent research and development. It has built a 5000 tons/year PPS resin industrial device and reached the world advanced level, making China the fourth largest PPS industry in the world after the United States, Japan, and Germany. Countries.
In the research and development of some special resins, some companies have begun to turn their sights on the production of special materials with high profits and stable markets. For instance, Qilu Petrochemical Plastic Factory has now turned its production focus into polypropylene-specific materials and has strengthened the use of pipes and medical equipment. , special requirements for film special materials research and development.
Industrial upgrading depends on independent research and development Overall, domestic synthetic resin manufacturers' products are still concentrated on general-purpose resins with relatively low profits and large fluctuations in market prices. Since the price of China's synthetic resin has remained high since last year, the profits of various resin varieties have been very good. Most companies have focused their efforts on energy expansion and production, and have relaxed their research and development on new products. In this regard, the industry pointed out that domestic synthetic resin companies should make greater efforts to strengthen independent innovation in order to achieve the entire synthetic resin industry upgrade.
At present, the gap between China's synthetic resin industry and foreign countries is still widening. The level of technology research and development is backward, the research and development cycle is long, and the industrialization rate is relatively low, which seriously restricts the overall development of the industry. Although China has reached an international advanced level in the research and development of some special engineering plastics, the general-purpose resin with the largest amount of usage has a significant gap with foreign countries both in terms of product quality stability and product brand comprehensiveness, especially for the research and development of special-purpose resins. The general lack of business. Experts pointed out that if we want to reduce the external dependence of China's synthetic resin, we must increase scientific and technological investment, strengthen product development, rely on its own technology to improve the level of the entire industry.

Drum cleaners are suitable for pre-cleaner of initial stage of material feeding procedure in many processing industry. Its main function is separating large impurities from raw materials.
It has high efficiency in pre-cleaning or cleaning paddy, corn, soybean, wheat, sorghum and other types of grains.
It is mainly used to remove the large impurities. When the materials fall into the rotating drum, the materials that smaller than the sieve mesh will fall into the outer cylinder, and large impurities will rotate with drum and gradually expel from the outlet.
