It is understood that according to the cooperation agreement signed between Sinopec and the Hebei provincial government at the end of 2004, the 300,000-ton crude oil terminal that was started last year will soon be completed. Recently, the two sides signed a supplementary agreement and agreed to jointly promote some of the projects in Hebei Province, including the development of petroleum refining and refined oil sales networks, including the construction of a new 10 million-ton refinery, a 1 million-ton ethylene plant in Caofeidian, and The stone refinery is transformed into a 10 million-ton refinery. Also in 2004, the Hebei Provincial Government and China National Petroleum Corporation also signed a cooperation agreement. The contents of the agreement also mentioned the construction of crude oil wharfs and petrochemical bases in Hebei as well as liquefied natural gas projects. Three months ago, PetroChina stated at a press conference for the discovery of Nanpu Oilfield that it plans to build a refinery in Nanbu Oilfield in Hebei Province and hopes to build a new chemical base in Caofeidian. According to reports, the same scale crude oil wharfs, oil refining, ethylene, and downstream project plans planned by the two groups were all supported by Hebei Province and reported to the National Development and Reform Commission.
The question now is whether the National Development and Reform Commission can agree to have two large-scale petrochemical projects in one place at the same time. In response to this, Hebei Province asked reporters several questions. Shanghai is a few? Dalian on a few? In their opinion, Caofeidian Port is the only natural harbor in the Bohai Bay that can build large-scale berths of over 300,000 tons without digging fairways and basins. It has developed traffic, and it is ample land that has been reclaimed from mud dug by the sea to make land and land. It is recognized as a place that is very suitable for the development of the petrochemical industry. Why can't it be fully utilized? Houston, the United States, concentrates 40% of the country's oil refining and 60% of ethylene. Why can't China concentrate properly?
However, Hebei also expressed cautiousness over the surge of petrochemical projects in Caofeidian. “The Caofeidian petrochemical project will eventually need to be weighed by the country, and the government will play a very important role in the planning,†said Gan Jiaan, president of the Hebei Petroleum and Chemical Industry Association. “No matter what the project is, for the development of the petrochemical industry in Hebei, both It is good."
Injection molding, also known as injection molding, is a method of injection and molding.Injection molding method has the advantage of production speed, high efficiency, can realize automation operation, breed of design and color is much, can shape by Jane to numerous, can from big to small size, and precise in dimension and product upgrading, can into complex shape parts, injection molding is suitable for mass production with complex shape product and processing field.
At a certain temperature, a screw is used to stir the fully melted plastic material, and a high pressure jet is used to enter the mold cavity.This method is suitable for mass production of complex shape parts and is one of the important processing methods.
