Description

一种竹基板、 竹地板及其制造方法 技术领域
本发明涉及一种竹基板、 竹地板及其制造方法， 属于竹加工技术领域。 背景技术
现有的竹制品地板或者其它家具板材， 通常由管状的竹筒制成， 由外到内， 竹壁由竹 青、 竹肉和竹黄构成， 在制作竹基板时， 通常是先将竹材截断， 然后在竹筒长度方向上分割 成多片竹条， 其横截面成圆弧形， 因此， 竹条圆弧形的两端部要切掉， 另外， 竹条上表面的 竹青由于含有蜡脂， 不利于粘胶而将其去掉， 竹条底面的竹黄由于比中间层竹肉的密度高很 多， 而在加工时板材易翘曲， 因此， 底层竹黄也需去掉； 最后加工成横截面为矩形的长条 片， 多个长条片需要使用粘接剂才能拼接成竹单板， 上述传统的加工方法 "去头掐尾" ， 在 很大程度上造成了原材料浪费， 竹子去内外侧表皮， 平整小竹条后， 竹子利用率不高， 生产 成地板或其它家具板材时时又需多层竹单板胶合， 因此工艺复杂， 工序多， 人工成本高， 原 材料损耗近 70%。 发明内容
