Wang Hanhong introduced that the calcium silicate cement board industry in 2018 can be summarized by keywords such as "hot", "exuberant", "supply in short supply" and "international exchange. In 2019, the calcium silicate cement board industry should focus on: seeking common quality improvement and promoting the long-term development of the industry!
As of the end of 2018, according to incomplete statistics, there are about 130 enterprises producing calcium silicate cement boards in China, with nearly 210 production lines, a production capacity of nearly 1 billion square meters (excluding those under construction and not put into production), and an output of less than 0.6 billion square meters. Compared with 2017, the production line increased by more than 10%. However, the output basically did not increase. The decline in output was mainly due to the impact of environmental protection, rising prices of raw materials and low-price competition in the market. Some enterprises stopped production, while some enterprises made low-density boards, diatomite boards and full-body boards, which reduced the output. The output of coated board (including integrated board) in 2018 is about 4500-5000 square meters, and the production capacity is about 0.1 billion square meters, which has an impact on the supply chain of substrates.

Jiangsu Aifu Xi New Building Materials Co., Ltd. Chairman Assistant Shi Zhiqiang
The meeting invited Shi Zhiqiang, assistant to the chairman of Jiangsu Aifuxi New Building Materials Co., Ltd., to make a special report on "the current situation and future development of China's fiber cement board and calcium silicate board industry".
Shi Zhiqiang introduced the development of fiber cement board and calcium silicate board enterprises and production lines in my country in the past 12 years, as well as the main product types, and analyzed the current problems in the industry. At present, the industry has serious overcapacity, and the actual production and sales are only 40% of the total production capacity, but the supply of products that the market really needs is insufficient.
Shi Zhiqiang analyzed the future development trend of China's fiber cement board and calcium silicate board industry: asbestos-free is the general trend; Environmental protection in production plants will be further upgraded; Products will be more abundant and diversified; Industry concentration will increase; The market is becoming more and more rational. In the future, fiber cement board and calcium silicate board have great potential as alternative materials in the fields of woodworking board, plywood, glass magnesium board, OSB board, waterproof and fireproof paper plaster board.
Wu Weiping, Deputy General Manager of Wuhan Building Materials Industry Design and Research Institute Co., Ltd.
Wu Weiping, deputy general manager of Wuhan Building Materials Industry Design and Research Institute Co., Ltd., introduced the application of grass pulp fiber in fiber cement board. Wu Weiping introduced that wood pulp fiber is a material that has a greater impact on the performance and cost of the board. At present, domestic wood pulp fiber mainly relies on imports. The price of wood pulp fiber is affected by international politics and economy, and fluctuates greatly. Therefore, the development of new alternative plants Fiber is conducive to controlling the production cost of enterprises and providing more material choices. The Technology Center of Wuhan Building Materials Industry Design and Research Institute Co., Ltd. cooperated with Professor Ying Hanjie's research group of the National Biochemical Engineering Technology Research Center of Nanjing University of Technology in 2018 to study the application of straw pulp fiber in fiber cement board.
Wu Weiping concluded that at present, the fiber cement board prepared by partial replacement or full replacement of wood pulp fiber has excellent performance, physical properties, mechanical properties and frost resistance can be close to pure wood pulp fiber cement board, and can reduce the cost by about 28.3-36.7. However, the straw pulp fiber will improve the porosity and water absorption of the board, and the straw pulp fiber has obvious water retention effect, and the board after suction filtration has high water content, which is not conducive to industrial production. The industrial production of straw pulp fiber will be further studied.
Lin Zhen, Director of Silicon Fiber Cement Technology Center in Elkem, Norway
Lin Zhen, director of the Technology Center for Silicon Fiber Cement in Elkem, Norway, introduced the reinforcement mechanism and failure causes of fiber composites. Lin Zhen concluded that the material characteristics of fiber-reinforced composite materials determine that its failure mode is completely different from brittle materials such as concrete. In addition to selecting appropriate basic cementitious materials and curing system, it is very important for the selection of reinforcing fibers. If reinforcement is used, the elastic modulus of fibers should be at least 2 orders of magnitude higher than that of the substrate. The role of fibers in composite materials is affected by the physical characteristics and chemical indexes of fibers, in particular, it is necessary to consider the compatibility of materials and the actual dispersion effect of fibers. The use of auxiliary materials is indispensable for the production of fiber composite materials. It is very important to understand the characteristics and functions of each auxiliary material for making good use of materials. Silica powder has obvious effects on increasing product strength and improving product durability. Silica powder can effectively improve delamination and protect cellulose fibers at the same time, extend the service life of cellulose fibers.

Xu Dingfeng, Deputy General Manager of Jinqiang (Fujian) Building Materials Technology Co., Ltd.

Jia Jian, vice president of research and development of Guangdong new element board industry co., ltd.
Jia Jian, vice president of research and development of Guangdong New Element Board Co., Ltd., introduced the performance parameters of fiber reinforced calcium silicate board for fire prevention. Jia Jian introduced that the formulation of a product's performance parameters cannot be separated from its application field. It is clear that fiber reinforced calcium silicate board should meet different performance parameter requirements in various building parts, and develop and produce corresponding board products according to the performance parameter requirements. Such as outdoor roofing products, outdoor wall products, indoor wall products, indoor ceiling products, indoor fire prevention products, indoor anti-explosion products, indoor explosion relief products, indoor humidity control products, phase change energy storage products and marine products, etc., none of the plates are "all-round" and can meet these application fields. If the ordinary indoor board is applied outdoors, there may be delamination, cracking, deformation, shedding and other phenomena; if the natural conservation board is applied indoors, there may be plate deformation, plate seam and even plate cracking and other phenomena. The improper application of the board will seriously affect the image of the fiber reinforced calcium silicate board in the eyes of customers, hinder the application and development of the fiber reinforced calcium silicate board, and affect the market's recognition of the fiber reinforced calcium silicate board series products.
