Reporters on June 9 from the China General Machinery Industry Association Gas Separation Equipment Branch learned that the past three years, China's blown film machine equipment market structure in the quietly changing, although the market is still metallurgical industry, but with the petrochemical, fertilizer industry Rapid development, blown film machine equipment in the petrochemical industry market share has increased from 14.5% in 2002 to about 30% in 2005. In addition, blown film machine equipment development trend is more obvious, manufacturing technology is also becoming more mature.
It is reported that in 2005 in the domestic market signed 25 sets of 30,000 or more blown film machine equipment, there are 10 sets for the petrochemical and fertilizer industry; industry-wide 20,000 or more blown film machine equipment, a total of 39 sets, of which 30,000 Level or more large blown film machine equipment accounted for 25 sets, is the history of large blown film machine equipment market the fastest growing year.
Experts believe that China's blown film machine equipment to large-scale development of the main reasons there are three: First, China's steel industry after the macro-control, the metallurgical industry to bring a new reorganization of the market demand; Second, petrochemical, fertilizer industry development, Especially large-scale blown film machine equipment has opened up new development space; Third, the domestic large-scale blown film machine equipment manufacturing technology matures and cost-effective advantages, won the more and more The more the trust of domestic users.
In addition, China's blown film machine equipment manufacturing industry in the new product development and new technology applications has made new breakthroughs, and promote China's blown film machine equipment manufacturing technology development. Among them, Hangzhou Oxygen Co., Ltd. for Iran to provide two sets of 63000m3 / h blown film machine equipment is currently the largest independent development of the domestic level blown film machine equipment, the device uses full low pressure molecular sieve purification adsorption, medium pressure air pressurized turbine Expansion machine, structured packing and all-stream argon technology in the oxygen compression process, to fill our own independent development of 60,000 grade blown film machine equipment blank; for the Central Plains Dahua 500,000 tons / year methanol project to provide 52000m3 / h Blown film machine equipment, the use of air pressure, oxygen nitrogen dual pump compression process, is China's largest domestic blown film machine equipment. According to reports, the current oxygen pressure of 4.6MPa or more use of chemical industry enterprises blown film machine equipment, are used liquid oxygen pump compression process, oxygen extraction rate of 95% to 97%, argon extraction rate of up to 70 % ~ 80%, these technical indicators are close to the international advanced level.
