Chen Wu, director of the Administrative Committee of the Zhanjiang Economic and Technological Development Zone, said that the two giants of Baosteel Group's 10 million-ton steel base and Sinopec's refining and chemical integration project have settled down, as well as the steel and petrochemical upstream and downstream industries. In effect, the formerly somewhat desolate East Island has achieved “ornate transformation†and has become a hot spot for investment. Investors have spread throughout the United States, Japan, the United Kingdom, Singapore, Hong Kong, Taiwan and other countries and regions.
According to reports, early this year, the original Zhanjiang Economic and Technological Development Zone and the East Island Economic Development Zone were successfully integrated. To undertake the upstream and downstream industries of steel and petrochemicals, Zhanjiang Economic and Technological Development Zone plans to build a 6.01 square kilometer steel supporting industrial zone and a 42.12 square kilometre petrochemical industrial park on the east island. At present, the East Island brings together domestic and international large-scale enterprise groups such as Shanghai Baosteel Group Corporation, Sinopec (8.02, 0.00, 0.00%) Group Corporation, and China National Offshore Oil Corporation, and the circular economy park is beginning to take shape. The park also combines the characteristics of many supporting industries in the steel industry and the long chain of petrochemicals in the middle and lower reaches of the petrochemical industry. It drives the construction of related industries in the two projects and undertakes industrial transfer. It has become the main battlefield for Zhanjiang to undertake domestic and international “transfer of industries†and “labor transferâ€. The important economic growth pole of Guangdong West Wing.
In March 2008, a total investment of 140 billion yuan, led by Baosteel Group Zhanjiang 10 million-ton steel base project, was approved by the National Development and Reform Commission. Subsequently, the project invested RMB 3 billion in the Jianjiang Water Supply Project for the project, as well as supporting the 10 million-ton-class iron and steel base project. The construction of the East Island Cross-sea Bridge project on Shugang Road was started.
In August last year, the total investment of more than 60 billion yuan, China's largest joint venture project "Zhongke refinery" officially settled in East Island. In September of the same year, the total investment was 3.2 billion yuan, and the 5 million ton pellet production line of Longteng Logistics, which was a supporting project of Zhanjiang Iron and Steel Base, was completed and put into operation. In addition, Baosteel Group also built two new 5000-ton-class integrated dry bulk berths and a 5,000-ton-size jetty berthing dock on East Island. This move was seen as a substantial early stage of Baosteel's Zhanjiang project launch. .
According to the analysis of economists, with the successive setbacks of Baosteel Group's 10 million-ton iron and steel base and Sino-Sciences' integration of refining and chemical integration, the “reactor response†triggered by nonferrous metal processing and mechanical equipment The downstream chemical industries such as manufacturing industries, as well as fine chemical industries such as synthetic resins, synthetic fibers, synthetic rubber, pesticides, dyes, flavors, fragrances, paints, adhesives, etc., have “combined†East Island. At present, the East Island Sea-crossing Bridge connecting Zhanjiang City has been completed, and the East Island will become the most powerful engine for the rapid socio-economic development of Zhanjiang.
Synthetic cryolite is a white crystalline powder or a sandy-size granularity, and a pinkish crystalline powder or a sandy-size granularity as well. Sp.gr.2.95-3.01g/cm3, melting point about 1000°C, specific heat 1.056j/g°C at 18-100°C. It`s slightly soluble in water, but insoluble in anhydrous hydrogen fluoride. The content of its crystal water will be decreased while the increasing of the molecular ratio, therefore its loss on ignition will be also decreased while the increasing of the molecular ratio. After the paste of synthetic cryolite with different molecular ratio dehydrates, the loss on ignition at 800°C will appear 10.34%, 6.22% and 2.56% when the molecular ratio reaches 1.74, 2.14 and 2.63 reactively.
Uses:
It`s mainly used as a flux in the aluminum smelting by fused-salt electrolysis; also an opalizer in the manufacture of enamel; an opacifier and auxiliary solvent of glass and enamel; an insecticide of crops; a flux in aluminum alloy casting; and in the production of ferrous alloy and effervescing steel; as well as a wear-resistant filler for Resin and rubber-boned Abrasive wheels.
