At 10:00 on December 26, experts from China Petroleum and Chemical Industry Federation, Ministry of Environmental Protection experts and some domestic leading enterprises in polyurethane industry executives witnessed a new technology in Shaoxing Huachuang Polyurethane Co., Ltd.: water and carbon dioxide In a reasonable proportion, under certain temperature and pressure with other additives organic fusion, 'tick' out of the traditional foam process generated ozone natural enemies freon - hydrochlorofluorocarbons.
The same day, the technology through the China Petroleum and Chemical Industry Federation of scientific and technological achievements identified by the Chinese Academy of Engineering Chen Jianfeng appointed expert group was identified as' the supercritical carbon dioxide-assisted water-blown rigid polyurethane spray equipment and its application Technology 'is a clean production technology, to protect the ozone layer, reducing the greenhouse effect of great significance.The project provided equipment is the first set of the overall technology reached the international advanced level.On the same day, after observing the on-site technical demonstration, polyurethane leading enterprises such as Wan Wah Industrial Three companies and 'Hua Chong' to discuss cooperation.
According to Guo Xiaolin, deputy director of the MEP's Environmental Protection Cooperation Center, the large-scale industrialization of this technology can significantly advance China's implementation of the international convention on environmental protection, the time of the Montreal Protocol on Substances that Deplete the Ozone Layer.
It has been widely used in polyurethane foam in the field of insulation and cold preservation in refrigerators and freezers, etc. The hydrochlorofluorocarbons generated in the foaming process destroy the ozone layer and aggravate the greenhouse effect. According to the international conventions, China will stop completely by 2030 Production and use of hydrochlorofluorocarbons.
Forced to create opportunities. In recent years, 'Hua Chong' has been committed to the research and development of environmentally friendly polyurethane in December 2015, with the support of the Ministry of Environmental Protection, the company and Nanjing Forestry University joint development of this new technology and success, the current China has won two invention patents, with independent intellectual property rights in September this year, the United Nations Development Program officials made a special trip to visit the technology, give a high degree of recognition.
It is reported that China's annual consumption of polyurethane foam spray over 100,000 tons, accounting for more than one-sixth of the world.According to the China Plastics Processing Industry Association estimates that the use of 'new technology' will enable China to reduce emissions of at least 700 million tons of carbon dioxide per year. The national carbon emission trading market price of 45 yuan per tonne calculation, an annual economic benefit of 315 million yuan.
Not only that, the spray foam produced by this technology has better performance and lower cost. "This spray foam does not deform at minus 162 degrees Celsius, and the overall production cost can also be reduced by 10%." Xiang Hua, general manager of CRE Estimated that in production and sales of 1000 sets of dollars, the company can achieve sales of 200 million yuan.
