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

刨花板暴露在表面霉菌的侵袭下。表面霉菌在木屑中的分解能力较差，但会显著降低刨花板的强度。表面霉菌在木材颗粒之间的空隙中生长。因此，人们认为木材颗粒和胶水之间的接触点被表面霉菌破坏了。使用带有防腐剂的胶水有望提高对表面霉菌腐烂的抵抗力。木屑的化学改性并没有提高木材抵抗表面霉变的能力。

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.
