Straw board production line equipment

Straws and isocyanate resin (MDI adhesive) are used as raw materials in the manufacture of homogeneous strawboard. Through procedures such as cutting, hammering, drying, glueblending, mat forming, pre-pressing and hot pressing, edge trimming and sanding, etc., straws are made into an environment-friendly board which is free of formaldehyde and with a density of 500-850 kg/m3. In 2003, the company developed the first homogeneous strawboard production line with a yearly capacity of 50,000m3 in China. One of the 863 National Scientific and Technological Innovation Projects of China, Backed by the strong technical force of Yantai Wanhua Group, which has developed a unique core process technology of “macromolecule polymerization harening structure”, under the unique chemical combination of environment-friendly polyurthane adhesive, and in conjunction with the complete production line for new-type strawboard, which isuniquely developed and continually upgraded by our company, a new generation of environmental substitute for wood panels, the first of its kind in China, is developed --- ecological board. The success of the project not only filled in a domestic gap, but also signaled that the products had led the innovation of Chinese panel machinery to a new stage. At the same time, it made China have the strength to compete with manufacturers from Finland, Canada, the United Kingdom and other countries. The equipment has been tested by the State Quality Supervision and Testing Center of Woodworking Machinery. All technical performance indexes are in accordance with relative national standards. And the production line has passed the technical appraisal by the Science andTechnology Commission of Henan Province. Produced strawboards have been inspected by the Nanjing Panel Quality Supervision and Inspection Station, and have proved to be in keeping with the requirements of GB/T21723-2008 Wheat (Rice) Strawboard. Recently, the company has developed a complete continuous roller pressing strawboard production line to better utilize agricultural straws.
