Wanhua Ecoboard, the panel division of Chinese MDI glue producer Wanhua Industrial Group, has ordered two lines from Dieffenbacher that will enable it to begin producing straw-based Supermechanical Strength Particleboard (Super PB) in 2023. Wanhua Ecoboard has now ordered 10 production lines from Dieffenbacher.
The production process of Super PB mixes standard core-layer flakes with slender, long core-layer flakes, enabling a board density up to 30 kg/m3 lower than usual. This leads to substantial savings in raw materials such as straw, wood and resin, and electrical and thermal energy without compromising board properties.
Wanhua will install its new lines in Chenzhou, Hunan and Leshan, Sichuan. Delivery of the Dieffenbacher equipment is scheduled to start in September 2022 for line nine and in October 2022 for line 10. Start-up of both lines is planned for the 2Q 2023. Once the new plants are in operation, Wanhua will reach a production capacity of more than 2.5 million m3 per year with its 10 Dieffenbacher lines.
