“零甲醛刨花板”系指用非醛类胶粘剂生产的没有甲醛释放的刨花板,可以满足目前世界上对甲醛释放限量要求最高的日本刨花板标准JISA5908—2003中的F☆☆☆☆级刨花板的要求。用异氰酸酯(PMDI)胶粘剂生产刨花板的生产工艺,涉及到热压过程中的脱模、热压工艺、低施胶量均匀施胶等诸方面的新设备、新技术,只有这些问题解决得好,才有可能生产出好的板材。 相似文献

For determination of formaldehyde release from plywood and composite boards test procedures applied for the testing of particleboard were examined. The formaldehyde content determined by perforator method permits conclusions to be drawn as to the expected formaldehyde relese. The corresponding correlation is given, the result of comparative examinations of plywood and composite boards from different manufacturers proves that the use of suitable urea formaldes adhesives and special hardeners and upon consideration of some technological pecularities, these materials can certainly be produced with a formaldehyde emission ≦0.1 ppm for their favoured use in furniture manufacturing. 相似文献

Physico-mechanical properties of particleboard fabricated from heat-treated rubberwood particles were investigated. Reduction in water absorption and mass loss were observed in heat-treated rubberwood particles, and it was associated with the properties of particleboard. The density and moisture content of the particleboard decreased with increasing treatment temperature and time. Heat treatment of particles improved the dimensional stability of the particleboard, but the mechanical properties were adversely affected. 相似文献

Relative percentage of moisture content of surface and core layers in pine tannin-bonded particleboard influences markedly the internal bond (IB) strength of the board. This is due to the differential compression exercised on the layers related to their moisture content. The moisture content differential between surface and core layers in particleboard during pressing is a determining parameter for the internal bond (IB) strength of particleboard. In the case of tannin adhesives where these differences can be more pronounced than for synthetic adhesive the effect is more easily observable. 相似文献
