Deterioration of Particleboard by Surface Mold and Preventive Method of It.

刨花板受到表面模具的侵蚀。表面霉菌对木材颗粒的分解能力较差，但对刨花板的强度有较大的影响。在木颗粒之间的空隙中观察到表面霉菌的生长。因此，可以认为木材颗粒与胶水之间的接触点受到表面模具的破坏。使用含有防腐剂的胶水有望提高对表面霉菌变质的抵抗力。对木材颗粒进行化学改性并不能提高木材对表面霉菌腐蚀的抵抗力。

Particleboards were exposed to the attacks of surface moulds. The surface moulds had poor decomposing-ability in the wood particles, however, they considerably decreased particleboard strength. The growth of surface moulds was observed in the spaces among the wood particles. Accordingly, it is considered that the contact points between the wood particles and glue were deteriorated by the surface moulds.Using of glue with preservatives was expected to increase the resistance to deterioration by surface moulds. The chemically modification of wood particles did not improve the resistance to the deterioration by surface moulds.
