Research Status on Wood Deresination

The resin-rich wood without deresination process will result in the exudation of resin, which will affect the painting performance of wood products. So it is important to remove resin in the wood industry. Through comparative analysis of the deresination methods, the results show that: (1) At present, the most studied deresination methods are high-temperature steaming method and alkaline liquor method, the former is more mature and the latter has higher degreasing rate; (2) Pinus massoniana and Larix gmelini are the most studied tree species, while cypress degreasing research is rare. According to the available research foundation of deresination technology and structural characteristics of cypress, some suggestions are put forward for providing reference for cypress deresination research.
