The domestic petrochemical industry demand rapid growth of granulator
With the rapid development of the global petrochemical industry, the demand for granulator is increasing rapidly in the domestic petrochemical industry. Dalian rubber plastics machinery co., LTD., announced that the company's domestic large plastic granulators will be put into production in new factory in May. But the reporter understands, domestic high-end plastic machine is in domestic big plastic machine market still is rare, the import product still is absolute advantage.
Taking plastic granulator as an example, it is one of the key equipments in large-scale ethylene project with high integration of mechanical, electrical and instrument and high automation control. Held recently in Japan kobe steel plastic granulator LCM user conference in China, Japanese experts said that the large-scale petrochemical plant driven plastic granulator, bigness and users on the mechanical stability of the unit and saving energy and reducing consumption demand is higher and higher.
According to the introduction, China has cooperated with foreign countries to manufacture some 70,000 tons of plastic granulators, but they have not succeeded. Today, large plastic granulation sets require production capacity of more than 50 tons per hour, which is equivalent to 300,000 to 400,000 tons/year, which is difficult to design and manufacture. Currently, only Japanese steel company of kobe steel, Japanese steel company, Farrell company and other large plastic granulating units are designed, manufactured and installed and debugging technology.
Compared with foreign products, China's plastic granulator manufacturing technology is relatively backward. Our country through the introduction of large granulating technology digestion and absorption, to complete the 70000-100000 tons/year polypropylene device mixing extrusion unit construction drawing design, and master the large granulator of various materials and related technology, but has yet to practical application. The design and manufacturing level of extruded granulator in China is far from that of foreign countries, and the large and medium-sized polyolefin devices are still dependent on imports.
The experts pointed out that the development of large-scale plastic granulators will be the main development of large plastic granulators.
In recent years, China's plastic machinery manufacturing industry has been developing rapidly and continuously. This point is reflected in the import and export side, not only shows that the Chinese plastic machinery has greatly increased in output, but also indicates that the domestic plastic machinery has improved significantly in quality and technology.
At present, China is a large manufacturer of plastic machinery and a large consumer of plastic machinery, but not a powerful plastic machinery. At present, China's plastics machinery manufacturing enterprise with considerable scale about 400, mostly in the economic relatively developed southeast coastal areas, mainly in the pearl river delta, Yangtze river delta. There are no plastics machinery manufacturers in Tibet, xinjiang, qinghai, ningxia and hainan provinces.
The reason is that the base of China's plastic machine is thin, and the high precision equipment still needs to be imported. With the expanding capacity of plastic machinery market in China, the total amount of imported plastic machinery has not decreased, which always accounts for 50% of the total market volume.
So far, our country large-scale ethylene project in plastic pelletizing has been imported, the required precision injection molding machine, electronics, communication engineering in the field of automotive industry for large injection molding machine, large multilayer blow molding machines, widely used in the packaging industry of two-way stretch film, multilayer blow molding machines, production equipment in the field of medical and health care needs of precise extrusion machine, has been relying on imports.
On the one hand, the levels of plastic machinery in China compared with advanced countries, there is a gap, in particular, some technical difficulties, such as precision injection molding machine, large-scale pelletizing, domestic production, market and the urgent need, really need to import; On the other hand, the performance and quality of domestic equipment are no worse than those imported, which can meet the requirements and import from abroad. In order to solve this problem, the plastic machinery industry will further improve its own development and innovation ability, and the country needs to be further improved in its management. However, China's molding machine manufacturers have been working hard to integrate internationally and actively participate in international competition.
From the development speed and the main economic indicators, in the mechanical industry of more than 190 industries, plastics machinery is among the best. Nowadays, the annual production capacity of plastic machinery in China is about 200,000 (sets), ranking first in the world. Only in the more than 100 injection molding machine manufacturer in ningbo, zhejiang province, ningbo Haitian group co., LTD. Production of "sea" brand injection molding machine series is complete, the export to the world more than 30 countries and regions, including Europe and the United States and other developed countries, foreign exchange earning about $200 million.
According to statistics, China's plastic machine industry is still at high speed. China is expected to produce 500,000 plastic machines by 2010.
Generally speaking, the production capacity of general plastic machinery products in China is excessive. The company is currently undergoing technological transformation, and it is important to add some high-efficiency, high-precision equipment and testing equipment to improve the product development and innovation ability.
No diamond, no porcelain work. The molding machine industry must want to "break the cocoon" again, there are a lot of supporting work to make up.
