                New technology makes Freon no longer unscrupulous.

                At about 10:00 am on December 26, experts from the China Petroleum and Chemical Industry Federation, the Ministry of Environmental Protection and the head of some leading polyurethane enterprises in China witnessed a new technology of Shaoxing Huachuang Polyurethane Co., Ltd. in Beijing: water and carbon dioxide in a reasonable proportion at a certain temperature and pressure with other additives. Machine fusion, "eliminate" the traditional foaming process in the ozone layer of natural enemy Freon - hydrochlorofluorocarbons.



                On the same day, the technology was appraise through the scientific and technological achievements organized by the Federation of petroleum and chemical industries of China. The expert group headed by Chen Jianfeng, academician of the Chinese Academy of Engineering, has appraised that this "supercritical carbon dioxide assisted water foaming rigid polyurethane spraying equipment and application technology" is a clean production technology, which is of great significance to protect the ozone layer and reduce the greenhouse effect. The equipment provided by the project is the first set in China, and the overall technology has reached the international advanced level. On the same day, after observing the on-site technical demonstration, three polyurethane leading enterprises, such as Wanhua Industrial Co., Ltd. and Huachuang, held talks and cooperation.



                Guo Xiaolin, deputy director of the Environmental Protection Foreign Cooperation Center of the Ministry of Environmental Protection, believes that once the technology is industrialized on a large scale, it will greatly advance China's implementation of the Montreal Protocol on Substances that Deplete the Ozone Layer, an International Convention on environmental protection. It has been widely used in polyurethane foam such as fridge, cold storage and other fields, resulting in the destruction of the ozone layer caused by HCFCs in the foaming process, which has intensified the greenhouse effect. In accordance with international conventions, China will completely stop producing and using HCFCs in 2030. It will create opportunities. In recent years, "Huachang" has been committed to the development of environmentally-friendly polyurethanes. In December 2015, with the support of the Ministry of Environmental Protection, the company and Nanjing Forestry University jointly developed this new technology and achieved success. At present, the company has obtained 2 patents for invention in China, with independent intellectual property rights. In September this year, the officials of the United Nations Development Programme made a special trip to inspect the technology and highly recognized it.



                It is reported that the annual consumption of polyurethane foam in China exceeds 100 thousand tons, accounting for more than 1/6 of the world's total. According to the Chinese Plastic Processing Industry Association, the use of "Huachuang" new technology will reduce carbon dioxide emissions by at least 7 million tons annually. According to the national carbon emission trading market price of 45 yuan per ton, the annual economic profit of 315 million yuan. Not only that, the spray foam made by this technology has better performance and lower cost. "This spray foam does not deform at zero 162 degrees Celsius, and the total production cost can also drop by 10%." Huachuang General Manager Xiang Minghua estimates that the annual production and sales of 1000 sets, the enterprise can achieve sales revenue of 200 million yuan.
