摘要
为了探索杉木Cunninghamia lanceolata制材板皮的最佳梳解加工工艺和设计制造理想的梳解机压辊,对杉木制材板皮进行了径向无约束辊压处理,研究了不同厚度、不同含水率、不同压缩率下杉木制材板皮辊压制备梳解加工坯料的情况。结果表明:①杉木制材板皮的厚度、含水率、压缩率对其辊压力有较大的影响;辊压的较佳工艺参数为:压缩率约为50%,含水率约为50%;②杉木制材板皮辊压处理后,厚度缩小,宽度得到了扩展;③杉木制材板皮辊压后,细胞都存在着不同程度的变形,但整体大部分回复,细胞被挤压,细胞腔变小而细胞壁未受到破坏。
To probe optimal combing technologies and to design and manufacture the best possible rolls for a combing machine, sawmill slabs of Chinese fir （Cunninghamia lanceolata） were rolled radially without in cross direction. Thickness, moisture content, and compression rate were studied by forming combing processing blank using rolling pressure. Results showed that 1 ） thickness, moisture content, and compression rate with better rolling pressure technology meant a compression rate and moisture content about 50%. Also, 2） after rolled pressure treatment, the thickness of the slab decreased and the width increased. In addition, 3） after rolled pressure, Chinese fir cells had various distortions, for instance cell compress and a diminished cell cavity, but the cell wall was not destroyed, nevertheless, later most of the cells returned to normal.
