Study on modification of Chinese fir for furniture and floor by resin impregnation
摘要
Abstract
Chinese fir is one of the important fast⁃growing tree species in the south China, but there are many defects in its material properties, which limit the further development and utilization of Chinese fir in the furniture and floor. One of the important methods to solve the contradiction between supply and demand of wood and the shortage of furniture and floor wood is to improve the comprehensive utilization rate of Chinese fir by impregnation modification. At present, the main resin for impregnate is UF, PF, polyvinyl formal and MF resin, in which the application of PF is more common, and the modification effect also the most significant. In the process of impregnation modification, the main methods are vacuum treatment, vacuum pressure, pressure impregnation or vacuum impregnation after extraction. Roll impregnation as rapid impregnation method of wood processing under normal temperature and pressure conditions, can also be for Chi⁃nese fir impregnation modification. Vacuum stack pressure method not only ensure drugs completely penetrate into the wood of Chinese fir, but also prevent crushing under pressure. The different technological parameters of impregnation and curing conditions had different effect for the properties of modified wood. Such as immersion time had great effect on the water absorption rate and thickness swelling rate. And the processes have the relationship and mutual influence, such as hot pressing temperature and time is closely related to compression deformation recovery rate and static bending strength. Final, the development direction and application prospect of impregnation modified Chinese fir in the furniture and floor industry was also discussed. The results can provide guidance and reference for further research and application of Chi⁃nese fir impregnation modification.关键词
