木材切片是研究木材构造和识别木材的重要手段,而切片材料处理是否得当,对切片的质量关系极大,特别是对硬度很大的木材的软化和腐朽松软木材的组织固化或硬化。例如蚬木的端面硬度高达1000千克力/厘米~2以上,因此材料必须经过软化处理才能切片;相反从地下挖掘出来作考古文物研究用的几千年前的木材,往往组织松软、腐朽、霉烂,因此在切片前材料需要经过适当固化乃至包埋处理;有些部门送检的如木屑等微小材料,也须进行包埋处理,使其体积加大,才能进行切片。
Timber slicing is an important method to study timber structure and identify timber. Whether the slicing material is properly handled or not depends on the quality of the sliced slice, especially on the softening and decaying of hard wood and the curing or hardening of decayed wood. For example, alder wood has an end surface hardness of up to 1000 kgf / cm 2, so the material must be softened to be sliced. On the contrary, the timber thousands of years previously excavated from the ground for researching archeological artifacts are often loose, decayed and rotten , So the material before slicing need to be properly cured and even embedding treatment; some departments such as sawdust and other small materials to be seized, it must be embedded to make it larger, in order to carry out slicing.
