Abstract:In this paper, a new method is described for determining the resin distribution on wood chip surfaces. A liquid UF resin was stained into red with rhodamin B. for spraying on the chip surfaces. The samples were photographed with color positive films used as a image. The percentage of resin coverage on the chip surfaces was obtained through a image processing method. A spectrophotometer was used to determine resin content by means of comparision sample image to standard image.The advantage of image method is not related with size and geometrical shape of wood chip and can be used to determine both the percentage of resin coverage and resin content on the same surface of wood chip.In this pater it is proposed that the image processing might be furt her developed for determining the three dimensional resin distribution on the wood chip surfaces. It is significant to develop resin distribution idea and complete method for determining resin distribution.
