Fourth Generation Refrigerant Gas to Replace the Phase-Out Third Generation

"The phase-out schedule of the third-generation refrigerant HFC series products has been determined, but the fourth-generation refrigerant HFO series is currently under the patent control of Western countries. We must hurry up to develop our own products, the time is short." At the Council of Zhejiang Fluorine Materials Industry Technology Innovation Strategic Alliance held in Huzhou last week, the Secretary-General of Zhejiang Fluorine Chemical Industry Association, the Fluorine Materials Technology Innovation Strategic Alliance Zhang Zengying, consultant to the Secretariat, said.

Zhang Zengying pointed out that due to the high GWP of HFC products, which belong to the scope of greenhouse gases, the Paris Agreement and the Montreal Kigali Amendment have determined the phase-out schedule of the third-generation refrigerant HFC series products. my country has formulated a plan to reduce HFC refrigerants, with a 10% reduction target by 2029 and a 20% reduction target from 2030 to 2035... But the current situation is that the third-generation refrigerant HFC produced and sold by domestic enterprises We must have a countermeasure and plan to develop the fourth-generation refrigerant HFO series products as soon as possible.

With the rise of national strategic emerging industries, our country has also begun to attach great importance to the development of high-end fluorine-containing new materials with excellent performance. Fluorochemical new materials have become one of the key new chemical materials developed by the country. "Although Zhejiang Province has the National ODS Substitute Engineering Technology Research Center and the National Fluorine Materials Engineering Technology Research Center, the results of the combination of academia, research and production are not obvious, and the actual research and development capabilities and funds are obviously insufficient, which cannot keep up with the pace of international advanced product introduction. It is still far from the goal of the Zhejiang Provincial Government that the output value of new materials such as high-end fluorosilicon polymers and fluorine-containing functional membrane materials will exceed 1 trillion yuan by 2022. Some product research and development have not started at all, and they are forward-looking. There are not many patents for fluorine chemical products with independent intellectual property rights." Zhang Zengying said.

In addition, Zhang Zengying also pointed out some other problems faced by the fluorine chemical industry, such as the upgrading of production equipment and control systems, which requires multiple related industries to work together. In addition, due to environmental and safety factors, fluorite mining is now strictly controlled, which is a correct measure, but it also leads to the inability to connect fluorite mining, resulting in a shortage of fluorite and rising prices. How to properly handle this The question is worth investigating.
