In order to obtain the optimal impregnation process of bamboo bundles, the effects of four factors, including solid content of phenol formaldehyde, adhesive impregnation time, moisture content and cross section area of bamboo bundles, on adhesive impregnation content of heat-treated bamboo bundles were investigated by taking mao bamboo bundles as the raw materials. The results show that under the same conditions, the adhesive impregnation content of bamboo bundles increased rapidly with the increase of solid content of phenol formaldehyde, the increasing trend slowed down as the adhesive impre...
