The present application relates to hot pressing control technical field, disclose a kind of fine woodworking board hot pressing carbonization linkage control method and system, the method includes: obtaining the rebound of plate blank to be pressed, and obtain the state parameter of plate blank to be pressed.According to rebound and state parameter, determine whether plate blank to be pressed is in rebound stagnation risk state.When in, determine the dominant risk state.When in rebound dominant risk state, carry out slow pressure rise and shape stability, according to the thickness change of plate blank compression Limit speed temperature rise and decompression steam of edge portion, after steam end, carry out final pressure curing under the condition of limiting edge portion temperature rise upper limit.When determining in stagnation dominant risk state, carry out edge portion limited speed temperature rise, according to the surface temperature difference of edge portion and center and the thickness change of plate blank compression Decompression steam is carried out, after steam end, final pressure curing is carried out.When not in, carry out reference hot pressing control.The present application inhibits edge portion carbonization, improves internal bonding quality, improves product qualification rate.

This invention provides a novel bamboo pallet manufacturing process, relating to the field of pallet processing technology. The novel bamboo pallet manufacturing process includes preliminary treatment, pre-processing, mid-processing, and final assembly. The preliminary treatment includes bamboo cutting, bamboo impaction, and rough milling. Based on the conical shape of the bamboo, the bamboo is cut to the required length and dimensions according to product requirements and specifications. The bamboo segments are then split into pieces, sorted by thickness and width, and the outer green and yellow parts are removed. Through a combination of drying, carbonization, hot pressing, and cold pressing processes, along with subsequent curing treatments, the internal stress of the bamboo is effectively eliminated, significantly reducing its moisture absorption expansion and drying shrinkage rates. The resulting bamboo panels have good flatness and low warping. The pallets made from this process maintain excellent dimensional stability and structural integrity even under complex temperature and humidity environments, extending their service life.
