Shandong Dasifu New Material Industrial Park is located in the circular economy industrial park of Leling City, covering an area of 260 mu.It was established in May 2014 and was invested and constructed by Shandong Qingjieneng Environmental Protection Co., Ltd. to produce high-end environmentally friendly dye intermediates and high-grade water-based dyes , Water purifiers, tanning agents, feed preservatives, photocatalysts and other products and provide pollution control technology, environmental protection equipment, environmental protection engineering services for the society. The Industrial Park set up Shandong Dafufu New Materials Co., Ltd., Shandong Lujia Environmental Protection Engineering Technology Co., Ltd. and Zhonghe Shandong Sunlight Photocatalyst Co., Ltd., with a total investment of 1.25 billion yuan, and construction in three phases. Among them, the first phase invested 240 million yuan to build a 2,000-ton annual environmental dye intermediate, 5,000-ton annual high-grade water-based dye, and 20,000 tons annual water purification agent project; the second phase invested 460 million yuan to build 30,000 tons of annual feed preservation Agent project; the third phase invests 550 million yuan to build a 50,000-ton annual sunlight catalyst project. After the completion of the industrial park, the annual output value will increase by 1.55 billion yuan, and the profits and taxes will reach 360 million yuan, providing 460 jobs for the society. Relying on the technological advantages of Qingdao University, Tianjin University, and Tsinghua University, Dasfu New Material Industrial Park develops and produces high-end environmentally friendly dye intermediates and water-based dyes, using membrane separation technology, extraction and back extraction technology, and 1: 2 asymmetric complex dye orientation Complex technology, 1: 2 symmetric complex dye pressurized complex technology solves many industry problems such as environmental pollution, and the technical performance of the product reaches the international advanced level. Dasfu New Materials Industrial Park introduced the photocatalyst production technology of Kyoto University in Japan and built the first ultra-high activity photocatalyst production line in China. The photocatalyst function uses light energy as the energy source of the chemical reaction, accelerates the redox reaction, and excites oxygen and water molecules into extremely active OH ― and O 2 ― radicals, which can decompose almost all harmful to the human body or the environment Organic substances and some inorganic substances are quickly converted into water and carbon
