Ningxia Dingsheng Sunshine Environmental Protection Technology Co., Ltd. was established in 2009, located in Wuzhong Jinji Industrial Park, Ningxia, with an investment of more than 690 million yuan, covering an area of 50 mu. It has built a research and production base for “CO2 foam extruded board special equipment” and built a mechanical processing workshop. , equipment assembly workshop, research and development trial workshop, warehouse and scientific research office building. Mainly engaged in the research and development and production of special equipment for carbon dioxide foam extrusion board, the equipment developed can fully realize fluorine-free start-up and fluorine-free production. The company has completely independent intellectual property rights and has obtained more than ten invention and utility model patents.
The extruded board produced by the special equipment for carbon dioxide foamed extruded board has been tested by the Swiss SGS organization and has reached the European environmental protection standards. It has been exported to northern Europe, North America and other places and has been well received by customers. The “Using Carbon Dioxide to Replace Freon Production of Environmentally Extrusion Board Technology” (patent) was listed by the National Development and Reform Commission at the end of 2015 as “National Key Carbon Technology Catalogue”, which was promoted as a key low-carbon technology. The invention of “modified carbon dioxide injection system and method for extruded board” has obtained a number of national patents. The subject has also been funded by the Ministry of Science and Technology and obtained the certificate of scientific and technological achievements issued by Ningxia Science and Technology Department. In June 2016, the company participated in the “Second China-US Climate Summit” and won the “Best Low Carbon Technology Exhibition Award” issued by the National Development and Reform Commission. In 2018, “Special Equipment for Carbon Dioxide Foamed Plastic Board” realized large-scale production. In the first phase, it achieved annual production capacity of 40 sets and has been promoted and applied in Xinjiang, Hebei, Shandong and Anhui. The company’s equipment uses CO2 instead of Freon foam, and each production line will reduce the use of Freon by about 450 tons, equivalent to reducing carbon dioxide emissions by about 800,000 tons. Calculated by 23,000 yuan per ton of Freon, the carbon dioxide per ton is calculated at 1000 yuan, and carbon dioxide is used instead of Freon foam. Each production line can save about 10 million yuan for the extruded board production enterprise every year.
