成都木材综合工厂生产的挤压法刨花板,必须经过贴面以后才能使用。过去用单板贴面,存在着两个问题:一是原材料供应不足。由于单板是生产胶合板的主要原料,刨花板贴面所用的单板全是面背板,不能充分供应,影响刨花板生产能力的发挥;二是松木单板表面不美观,达不到作家具等的要求,一般只适用于建筑等方面,使用范围受到一定限制。为了充分发挥现有设备能力,提高木材综合利用水平,寻求单板贴面的代用材料和与之相适应的生产工艺,四川省成都木材综合工厂和四川省林业科学研究所协作,于1973年开始 Extrusion method particleboard produced by Chengdu Timber Integrated Factory must be used after veneer. In the past veneer veneer, there are two problems: First, the lack of supply of raw materials. As the veneer is the main raw material for the production of plywood, veneer veneer veneer used are all back and forth, can not be fully supplied, affecting the production of particleboard production capacity; Second, pine veneer surface appearance, not up for furniture and so on Requirements, generally only applies to the construction, etc., the use of certain restrictions. In order to give full play to the existing equipment capacity, improve the level of comprehensive utilization of timber, to seek alternative veneer veneer materials and the corresponding production technology, Chengdu, Sichuan Province, integrated timber plant and the Sichuan Provincial Forestry Science Institute, in 1973
