关于胶液在刨花上分布情况的研究

<正>在刨花板生产中,施胶效果的好坏直接影响着刨花板的各项物理力学性能,同时也关系到生产成本和经济效益;而施胶质量又和胶液在刨花上的分布密切相关。因此,对胶液的雾化情况和在刨花上的分布情况的研究就显得十分重要。

STUDY OF RESIN DISTRIBUTION ON THE WOOD FLAKES

Spray blending is a important way used in resin application. Therefore, both the size and the distribution of resin could effect directly the quality of blending. This study attempts to explain resin distribution on the flakes with theory and provide theoretical basis for raising the quality of blending by observing and calculating the atomization area, the average diameter of resin droplet, the amount of resin coverage and so on.This article considers that: ?Only resin droplets in inside ring of atomization circle are profitable because of the uniformity of resin drops and high distribution density. ② Smaller resin droplets may not mean better blending quality, because when resin droplets is smaller than the surface grooves (cell cavity and some cracks) blending quality will be lowered. In general it should be controlled that resin droplets must be larger than the width of the wood surface grooves.
