“Superfine wooden unit covered plywood” passed the new product appraisal of China Forest Products Industry Association
On January 7, 2023, the China Forest Products Industry Association organized experts in Beijing to conduct a new product appraisal on the “ultra-fine wood unit cladding plywood” jointly developed and produced by Shandong Shengchang New Materials Co., Ltd. and the Wood Industry Research Institute of the Chinese Academy of Forestry Sciences in the form of online and offline meetings.
The expert appraisal committee consists of Wu Yiqiang, academician of the CAE Member, Chu Fuxiang, president of the Chinese Academy of Forestry Sciences, Professor Chen Tianquan, vice president and acting secretary-general of the China Forest Products Industry Association, Shi Feng, chief expert and professor level senior engineer of the China Forest Products Industry Association, Wu Xiaosong, former deputy director of the Department of Rural Economy of the National Development and Reform Commission, Yu Zhiming, president of the School of Materials Science and Technology of Beijing Forestry University, and the director of the First Industrial Institute of the Industrial Development Planning Institute of the National Forestry and Grass Administration Zhang Zhongtao, a professor-level senior engineer, and Zhang Fangwen, the research and development director of Beixin Wood Industry, are composed of experts. Lu Bin, deputy director of the Wood Industry Research Institute of the Chinese Academy of Forestry, researcher Yu Wenji, project leader, Zhao Yunxuan, deputy general manager of Shandong Shengchang New Materials Co., Ltd., and personnel from the R&D Department attended the meeting. President Chu Fuxiang presided over the new product appraisal meeting.
Professor Chen Tianquan presided over and introduced the leaders, experts and relevant personnel at the meeting. Lv Bin, Deputy Director of the Institute, welcomed and thanked the experts at the meeting to guide the work of the Institute. The project leader, Researcher Yu Wenji, briefly introduced the new product research and development process and the major progress made on behalf of the new product research and development team, Zhao Yunxuan, deputy general manager of Shandong Shengchang New Material Co., Ltd., briefly introduced the production and operation of the enterprise and the cooperation with the Institute of Timber, Chinese Academy of Forestry Sciences. Dr. Zhang Fangda reported and introduced the research background, production process, product characteristics and application prospects of the new product “ultra-fine wood unit covered plywood”. The appraisal committee listened to the project report, reviewed the appraisal materials, watched the production line video, inspected the samples, and made inquiries and replies. The experts attending the meeting unanimously formed the following appraisal opinions:
The R&D team uses plywood as the core layer base material, ultra-fine wood units as the cladding material, and the surface ultra-fine wood units use isocyanate as the adhesive. By optimizing the wood materials, optimizing the shape and size of ultra-fine wood units, and adopting the key technologies such as independently developed high-pressure atomization sizing, continuous slab paving, and continuous flat-pressing one-time molding, the R&D team developed the ultra-fine wood unit cladding plywood with a new structure.
According to GB/T 17657-2013, the static bending strength of the product is 41.4 MPa along the grain and 32.2 MPa across the grain according to the test of the National Center for Quality Inspection and Testing of Wood-based Panels and Wood-Bamboo Products; Modulus of elasticity along grain: 5700 MPa, transverse grain: 3610 MPa; Surface bonding strength 1.78 MPa; The average bonding strength is 0.50 MPa; Water absorption thickness expansion rate 10.6%; Formaldehyde emission 0.029 mg/m ³。 The product has achieved large-scale industrial production and application, and the user feedback is good.
The appraisal committee agreed that the product reached the international leading level and agreed to pass the new product appraisal.
