| Abstract: | In order to overcome the shortcoming of high temperature baking board, during the study on pencil board improvement,the following expetiments are conducted:1.the basic rule of basswood pencil board press drying and the relation between temperature,time and moisture content;2.the comparison of moisture absorption performance and brittleness between the board treated with baking and that dried with thermal pressing.The results show: pencil board can be thermally decomposed because of high temperature ,the moisture absorption quality and brittleness of pencil boark dried by high temperature pressing can meet the requirements of pencil production,and the board quality is stable.Moreover,thermal pressing solves the problem of environmental pollution created by baking. |

| Keywords: | pencil board measure stability dried with thermal pressing moisture absorption |
