At present, the comprehensive utilization rate of industrial by-product gypsum in the world is less than 5%, how to answer this major problem that plagues the global phosphorus chemical industry? On April 20, the reporter found a new answer at the Guizhou Phosphate Group Gypsum Green Application Products and Services Exchange Meeting - anhydrous gypsum and downstream decorative flooring, decorative materials, municipal materials, pipe profiles, packaging materials and other industries are coupled, which is expected to open a trillion-level packaging market.
In the Guizhou Phosphate Group Kaiyang, Xifeng Industrial By-product Gypsum Green Building Materials and Polymer Industrial Park, the reporter saw the world's first set of anhydrous gypsum production line with an annual output of 300,000 tons, and the crystal water content of gypsum is less than 0.5%, which can be used for the downstream production of building materials and polymer products in the industry;
He Guangliang, Secretary of the Party Committee and Chairman of Guizhou Phosphate Group, told reporters that this is a revolutionary breakthrough achieved by Phosphate Group in the high-value and efficient utilization of phosphogypsum, and is about to enter the trillion-level packaging market to realize the value, industrialization and green utilization of phosphogypsum resources. He Guangliang said that the recent joint issuance of the "Action Plan for the Comprehensive Utilization of Phosphogypsum" by seven departments including the Ministry of Industry and Information Technology is a major benefit to the development of industrial by-product gypsum business. As a phosphorus chemical enterprise with important influence in the country and even the world, the group has always regarded phosphogypsum as a "misplaced resource", and cultivated and built the R&D, production, promotion and application of gypsum green products as a green environmental protection industry. At present, the phosphate group has 100 million tons of industrial by-product gypsum resources, is the largest industrial by-product gypsum supplier in Asia, has invested a total of 3 billion yuan, built a gypsum new building materials, anhydrous gypsum as a polymer filling material and other industrialization paths, formed anhydrous gypsum packaging boxes, interlocking high-precision blocks, gypsum-based artesian flat series products, to solve the world problem of phosphogypsum governance to provide a phosphating program, is to achieve a new breakthrough in the development concept of "making good use of resources and benefiting mankind". According to Chen Zhonghua, chairman of Guizhou Phosphate Green Environmental Protection Industry Co., Ltd., the type II anhydrous gypsum produced by the company has excellent performance as a filling material or cementitious material. Compared with traditional corrugated boxes, anhydrous gypsum packaging boxes are more waterproof, more compressive, more wear-resistant, and have obvious price advantages, which can be used in many industries such as wine, agricultural products, fruits and vegetables, hardware and machinery, chemical and pharmaceutical. In addition, every 1 ton of anhydrous gypsum packaging box can reduce the felling of 0.8 tons ~ 1.1 tons of trees, and no wastewater is produced in production, which is the most ideal high-quality environmentally friendly packaging to replace traditional cartons. In the next step, the company will strengthen multi-party cooperation and expand the production capacity of the two products to meet market demand.
The performance problems of industrial by-product gypsum, which were previously reflected in the downstream, have also made breakthroughs. Huang Zhaoxia, a representative of the team of academician Qu Jinping and an associate professor of South China University of Technology, said that they have cooperated with Guizhou Phosphate Group to solve the problems of insufficient performance, low added value and weak market competitiveness of phosphogypsum products, which has added a heavy weight to the resource utilization of phosphogypsum. In the future, the team will jointly conduct in-depth research on phosphogypsum functional masterbatch development technology and equipment, high-phosphogypsum functional film blow molding technology, advanced manufacturing technology of polyolefin/phosphogypsum composite hollow lattice board, and high-efficiency molding technology and equipment of ultra-high molecular weight polyethylene transportation pipeline for slag slurry through the project of Academician Qu Jinping Guizhou Phosphate Joint Laboratory to increase competitive advantage. Hu Zhengyang, deputy secretary-general of the China Packaging Federation, believes that Guizhou Phosphate Group provides more possibilities for the green development of the packaging industry. In the future, green packaging must vigorously rely on scientific and technological innovation achievements, guided by green new material technology and circular economy recycling technology, guided by the development thinking of the whole life cycle and the whole industry chain, and supported by the coordinated production and manufacturing system, recycling system, recycling system and regulatory certification system, overall planning, coordination of all parties, and promotion of the healthy development of the industry. Liu Zhihao, vice chairman of the Solid Waste Disposal and Utilization Special Committee of the China Building Materials Circulation Association, said that anhydrous gypsum packaging boxes and high-precision gypsum blocks have expanded a new scenario for the comprehensive utilization of phosphogypsum. In terms of economy and functionality, the packaging box has formed a new breakthrough in the industry. From the perspective of industrial development prospects, a trillion-level market scale will be formed.
At present, the Sixth Engineering Company of China Metallurgical Group has adopted anhydrous gypsum building materials produced by Phosphate Group in related projects. Practice shows that the performance of its products in heat preservation, sound insulation, heat insulation and other properties are good. In the next step, they will carry out comprehensive cooperation with Phosphate Group in the field of anhydrous gypsum building materials. More than 200 heads of scientific research institutions, industry associations and enterprises from all walks of life in construction, packaging and new materials participated in the exchange meeting, and inspected the Phosphate Group Kaiyang and Xifeng Industrial By-product Gypsum Green Building Materials and Polymer Industrial Park. At the meeting, Phosphate Group also signed a strategic framework cooperation agreement with South China University of Technology, China Metallurgical Group Co., Ltd., Guizhou Yiyuan Holding (Group) Co., Ltd., and Zhejiang Huize Science and Technology Development Co., Ltd.
