On October 18, Dalian Rubber and Plastic Machinery Co., Ltd. held the production ceremony of 350,000 tons/year and 200,000 tons/year polypropylene (PP) equipment of Daqing Long Oil and Petrochemical Co., LTD. This is another major achievement in the process of promoting major equipment localization, marking a new peak in the R & D and manufacturing capacity of Big rubber and Plastics.

The production of two sets of large extrusion granulation unit is Daqing Longyou Petrochemical "tailor-made" new products, the contract amount of 130 million yuan, of which the annual output of 350,000 tons of polypropylene extrusion granulation unit is currently the largest specification of polypropylene equipment domestic extrusion granulation unit.

It is understood that the project is one of the key projects of the national "petrochemical industry planning and layout scheme", which is of great significance to accelerate the construction of Daqing's "oil and tail" industrial pattern, promote petroleum intensive processing and the transformation and upgrading of "oil city". At the same time, it also refreshed the big rubber and plastic company at the same time down the line of 2 sets of large heavy extrusion granulator units, within 1 year delivery of 6 sets of large extrusion granulator production capacity of the new record, to achieve the company in the R & D producing countries of the heavy instrument. — A new leap in the field of large-scale granulation units." After China has the strong strength of mass production of large-scale extrusion granulation unit equipment, it has completely broken the monopoly of foreign enterprises on the Chinese market, and the price rise of similar products in foreign enterprises has slowed down. "Said Wang Yuanjiang, chairman of Da Rubber & Plastics.

Because the user required the two equipment to be delivered at the same time, this is unprecedented in China, and brings great challenges to the big rubber and Plastics production organization. Big rubber and Plastic take this opportunity to meet the difficulties, relying on the mature experience accumulated in the development of large-scale extrusion granulation unit in the past, the technical experts in the enterprise formed a project research team, for the core components such as gear pump, barrel, reducer design process improvement and structural optimization, transformation and upgrade the production process, super routine organization, super level play, Conquered one technical problem after another. Through unremitting efforts, the two equipments have been produced on schedule with guaranteed quality, and the performance indicators of the products have met the design requirements and reached the international leading level under the witness of the users and the inspection expert team. A major breakthrough has been achieved in the independent brand project, and new contributions have been made to the revitalization of the old industrial base in Northeast China with practical actions.

It is understood that the large extruded granulation unit is the key equipment in the petrochemical industry of large ethylene complete equipment. In the past 30 years, China's petrochemical industry large polypropylene extrusion granulation unit is completely dependent on imports, the market has been monopolized by the relevant companies in Germany and Japan for a long time, subject to others, so that the production cost of China's petrochemical industry is high, which seriously restricts the healthy development of China's petrochemical industry. As the cradle of the development of China's rubber and plastic machinery, which has developed more than 90 first sets of large extruded granulation units, Big Rubber and Plastic actively responded to the call for the localization of national major equipment, from the first set of 200,000 tons/year extruded granulation units to the successful production of the first 350,000 tons/year domestically produced extruded granulation units in 2019, Big rubber and Plastics has broken the monopoly of foreign manufacturers in this field in one fell swoop, making Big Rubber and Plastics the only manufacturer of large extruded granulation units in China and the fourth in the world. Especially in the past 10 years, Big Rubber and Plastics has sold 20 sets of large-scale extrusion granulation units with a contract value of 1.2 billion yuan, and cooperated with upstream and downstream equipment manufacturing enterprises to achieve a cumulative output value of more than 70 billion yuan, filling a number of gaps in this field in China. The quality and performance of its products have been recognized by users such as Sinopec and CNPC, which has effectively promoted the process of localization of major equipment in China's petrochemical industry and enhanced the comprehensive strength of China's petrochemical equipment.
