Gypsum board industry development trend

Gypsum board industry development trend

1. Eliminate backward production capacity and improve the large-scale and automation level of production lines. The large-scale gypsum board production line has a series of advantages, such as good and stable product quality, fast production speed, high output, high automation level, less operating workers, lower energy consumption per unit area, less pollution emissions, low construction cost and less land occupation.
Eliminate production lines of less than 10million square meters, and encourage the construction of paper gypsum board production lines of more than 30million square meters; Strengthen the research and development of key technologies and core equipment (such as desulfurization gypsum and phosphogypsum processing technology and equipment, high-performance mixer, high-efficiency and energy-saving gypsum calcination equipment and gypsum board drying equipment); Research, develop and promote new energy-saving heating system equipment, and eliminate backward heating methods of steam boilers and heat-transfer oil furnaces; Further develop DCS automatic control technology based on the whole process of gypsum board to realize distributed and networked control technology among various sections.
2. Promote the application of 100% desulfurization gypsum and phosphogypsum to realize the comprehensive utilization of industrial waste residue resources. Guided by scientific development, following the concept of circular economy development, relying on strong policy support, we should strengthen the comprehensive utilization of resources, replace natural gypsum with desulfurized gypsum and phosphogypsum to the greatest extent, and vigorously develop paper gypsum board and other related products with advanced and mature technology; At the same time, research and develop high value-added comprehensive utilization technology.
In order to promote the healthy and rapid development of the comprehensive utilization of desulfurization gypsum and phosphogypsum, we should do a good job of policy support; Increase technological research and development efforts and capital investment, accelerate technological transformation, and establish comprehensive utilization demonstration projects; Formulate technical standards for desulfurization gypsum products of coal-fired power plants, ensure the quality of desulfurization 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 cleaner production and circular economy. Gypsum raw materials, fuels, heat source schemes, energy consumption of gypsum calcining equipment and gypsum board drying equipment are one of the important factors affecting the investment of paper gypsum board. For the further development of gypsum calcination 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 structural adjustment of domestic paper faced 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 paper gypsum board, water-resistant paper gypsum board, sound absorption / veneer decorative gypsum board, phase change paper gypsum board, anti radiation paper gypsum board, green adsorption function gypsum board, formaldehyde removal paper gypsum board.
5. Do a good job in energy conservation, environmental protection, cleaner 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.
