Development prospect analysis of polyurethane foaming machine

  The foam produced by polyurethane foaming mechanism is the best insulation and energy saving material at present, and its performance indexes are better than the traditional XPS and EPS external insulation system. This kind of external thermal insulation system technology has been the national provinces and cities concerned leaders, experts attention. Ministry of slurry sampling a polyurethane building has been set up to save application promotion working group, and in the middle of October 2005 was held in Beijing "polyurethane wall energy saving technology international exchange", the national various provinces, municipalities and autonomous regions, and municipalities directly under the central government construction department (appoint) and technology energy saving wall change nearly hundred delegates to office, design and development unit.


  

China is the world's largest producer of refrigerators, in 1998 consumption of hard foam 80,000 ~ 100,000 t, used for oil pipelines, chemical storage tanks and industrial equipment insulation materials accounted for 15%; Building materials are another major application field of rigid polyurethane foam. In 2000, the consumption of rigid PUR foam in the construction industry was over 70,000 t. Due to the rapid development of China's construction industry, used in building insulation, sound absorption, decorative materials and mobile housing foam plastic accounted for 10%; Insulation for transportation accounts for 10%; Other accounts for 7.5%, furniture, clothing, bicycles and other consumption of large.


In addition, the development of China's automobile industry and motorcycle industry has also provided a broad market for molded soft PUR foam plastics. According to experts' prediction, due to the excellent plasticity of polyurethane and the strong practicability of material properties, the application of polyurethane in automobiles is expanding day by day. It is estimated that the demand for polyurethane in China (excluding Taiwan province) automobile industry will reach 44,100 t in 2005, among which 30,400 t will be consumed by cars and jeeps, 33,000 t by heavy cars, 7,200 t by light cars and 5,500 t by mini cars. The average consumption of each vehicle will reach 14.71kg.


  Polyurethane foam plastic is one of the most important polyurethane products, its wide range of USES, high performance: soft PuR foam plastics and semi rigid PuR foam plastics liner is mainly used in furniture and decoration materials, car mat, carpet backing, clothing lining, sound-absorbing materials, sports pad material, mattresses and instruments and packaging materials, etc. The main use of molded soft polyurethane foam is car seat cushion material and motorcycle, bicycle seat cushion, etc. However, rigid polyurethane foam is mainly used in refrigerators and cold storage as heat insulation materials, accounting for 57.5% of the total consumption of rigid polyurethane foam.

According to the data, the amount of imported fuel oil arrived in bohai bay in February was 830,000 to 840,000 tons, compared with 1.62 million tons in January calculated by xunsi, which dropped 750,000 tons to 46.3%.


Singapore led the way in February with 270,000 tonnes of fuel oil; Europe is second with 170,000 tonnes of fuel oil; The amount of fuel oil from southeast Asia is 160,000 to 170,000 tons, venezuela 90,000 tons and Russia and South Korea 70,000 tons each.
