Gypsum board industry development trend

                                               Gypsum board industry development trend

1. Eliminate backward production capacity and improve the scale and automation of production lines. The large-scale gypsum board production line has a series of advantages, such as excellent and stable product quality, high production speed, high output, high automation level, less operating workers, lower energy consumption per unit area, less pollution emission, low construction cost and less land occupation.
Eliminate production lines of less than 10 million square meters, and encourage the construction of production lines of more than 30 million square meters of gypsum board; Strengthen the research and development of key technologies and core equipment (such as the processing technology and equipment of desulfurization gypsum and phosphogypsum, high-performance mixer, high-efficiency and energy-saving gypsum calcining equipment and gypsum board drying equipment); R & D and promotion of new energy-saving heating system equipment, and elimination of backward steam boilers and heat transfer oil furnaces; Further develop DCS automatic control technology based on the whole process of gypsum board, and realize distributed and networked control technology among various sections.
2. Promote the application of 100% desulfurized gypsum and phosphogypsum to realize the comprehensive utilization of industrial waste residue resources. Under the guidance of scientific development, follow the development concept of circular economy, rely on strong policy support, increase the comprehensive utilization of resources, replace natural gypsum with desulfurized gypsum and phosphogypsum to the maximum extent, and vigorously develop paper gypsum board and other related products with advanced and mature technology; At the same time, high added value comprehensive utilization technology was developed.
In order to promote the healthy and rapid development of comprehensive utilization of desulfurized gypsum and phosphogypsum, we should do a good job in policy support; Increase technological research and development and capital investment, accelerate technological transformation, and establish comprehensive utilization demonstration projects; Formulate technical standards for desulfurized gypsum products of coal-fired power plants, ensure the quality of desulfurized gypsum, provide raw materials with guaranteed performance and quality for downstream production enterprises, and ensure the interests of waste recycling enterprises.
3. Efforts should be made to reduce energy consumption of products and develop clean production and circular economy. Gypsum raw materials, fuel, heat source scheme, energy consumption of gypsum calcining equipment and gypsum board drying equipment are one of the important factors affecting the investment of gypsum board. For the further development of gypsum calcining equipment and gypsum board dryer and the energy consumption of gypsum drying, reduce the production cost and meet the increasingly high national requirements for environmental protection.
4. Guide the application structure adjustment of domestic gypsum board products, from ceiling decoration to the development of building partition system; Increase the research and development of high-end products such as fire-resistant gypsum board, water-resistant gypsum board, acoustic / veneer decorative gypsum board, phase-change gypsum board, radiation proof gypsum board, green adsorption function gypsum board and formaldehyde removal gypsum board.
5. Do a good job in energy saving, environmental protection, clean production and industrial guidance of the whole gypsum board industry to ensure the healthy development of the gypsum board industry; In combination with the reform of wall materials, encourage and promote the application of gypsum board, do a good job in the development of downstream products of gypsum board, and expand the application field of gypsum board.
