摘要
用单张浸胶纸贴面基材的刨花板,其性能要求与国定标准GB4896-4905-85有所不同。最重要的是需要缩小未砂光板的厚度偏差,从国内生产装备条件分析,可达到±0.3mm。表面必须用细刨花,不宜用尺寸过细的粉尘挂面。基板密度不超出0.65—0.73g/cm^3。从现有的商品板分析,各项强度指标尚可适当降低,以节省胶料。规模为3万m^3/年及5万m^3/年的刨花板厂按以上要求生产优质基板是可行的。
The properties of particleboard used as substrate for overlaying with a single sheet resin impregnated decorative paper should have some differences from those specified in GB4986-4905-85 for general uses. Most grades of the domestic commercial particleboards have atained or even exceeded the specification class 1 of GB4986-4905-85. However, if any particleboard manufacturer attemts to use their own products for the above mentioned type of substrate, it is necessary to regulate some of their properties. The most important point is to decrease the thickness tolerance of the unsanded particleboard. Particles for surface layer must be fine enough because micro-particle fraction is much necessary on the board surface. The appropriate density of this type substrate should be around 0.68g/cm^3, within the range of 0.65g/cm^3—0.73g/cm^3. There would be no considerable difficulties to produce this type of substrate by the present domestic particleboard plants, especially in those having the scale of 30,000 to 50,000m^3/year.
