Reed and flax stalk was used as raw materials for making particle board.We had notonly investgated some important technological parameters including ratio of reed and flax stalk ad-hesive modification and hot pressing but also established a optimal manufacture technology ofmaking particle board According to the experiment result, when the ratio of reed/flax was 30percent,the bending strength and thickness swelling of the board could reach the first-grade re-quirement of GB/T 4879 92,but the internal bonding strength was lower than the standard ofGB/T 4897 92.We shall further study the adhesive modification and the surface treatment ofreed,to improve the properties of particle board from reed and flax stalk.
