随着胶合板生产的发展,要求扩大胶合板材树种。我省阔叶材树种较多,蕴藏丰富。在胶合板生产中已占一定的比例。但一些阔叶材树种的单板如枫香,由于收缩不均匀,干燥后成不规则的瓦楞形,而且易碎裂,给组坯作业带来较大的困难。出现产品因为叠离缝超过规定而降等的现象。外地曾做过提高表、底板含水率用“干——湿混合法”生产胶合板的试验,本试验目的在于提高芯板含水率,即当芯
With the development of plywood production, it is required to expand the plywood tree species. Hardwood species in our province more rich reserves. Plywood production has accounted for a certain proportion. However, some hardwood species veneer such as sweetgum, due to uneven shrinkage, after drying into an irregular corrugated shape, and fragile, to the group billet job more difficult. Appear because the products exceed the provisions of the stack slit down and so on. Field has done to improve the table, the floor moisture content with the “dry - wet mixing method” test plywood production, the purpose of this test is to improve the core moisture content, that is, when the core
