由于胶合板生产的发展,需要缩短胶合剂的固化时间,酚醛树脂胶合剂其性能较好,已成为一种主要的木材胶合剂。但目前国内使用的酚醛树脂胶,涂胶后芯板不经干燥,其热压时间较长,而且质量不很稳定。在批林批孔运动推动下,遵照毛主席“独立自主、自力更生”,“洋为中用”的方针,为解决上述问题,我们组成了生产、使用、科研三结合试验小组,参考有关资料,用国产 Due to the development of plywood production, the curing time of the adhesive needs to be shortened. The phenolic resin adhesive has better performance and has become a major wood adhesive. However, the current domestic use of phenolic resin glue, glued core board without drying, the hot pressing longer, and the quality is not very stable. In line with the policy of “criticizing the proletariat and the bodhisattva”, in accordance with the principle of “independence, self-reliance” and “foreign use” by Chairman Mao, we have formed a combined experimental group for production, use and scientific research with reference to the relevant materials Domestic
