竹材是人们极为熟悉的一种材料,它具有与木材相同或比木材更好的物理力学性能。竹子喜温好湿,生长极快,是一种轮伐期短(一般3～4年)、可更新的自然资源。湖南生产竹材制品历史悠久,人们利用其割裂性能,主要利用竹筒表层层-青蔑,编织竹器,竹材利用率仅30%左右。1979年,湖南省开始研制竹质建材,1980年投入批量生产。当时主要是利用生产竹器中废弃的竹黄蔑编成竹编席,经叠合、施胶、热压工艺制成竹胶合板,产品很快推广到建筑市场,后来扩展应用到机械产品的包装板、家具隔板和农用的打稻机、风车、谷仓等。1983年,由湖南省竹胶合板厂研制捣制混凝土用的竹胶模板。经过多次试验,他们采用竹器加工过程中的废料编成竹帘作骨架材料,与原竹编席复合热压,当年就成功研制出混凝土用竹胶模板。其主要性能为: Bamboo is a material that people are very familiar with. It has the same physical mechanical properties as wood or wood. Bamboo is very warm and wet, and grows very fast. It is a renewable natural resource with a short rotation (usually 3 to 4 years). Hunan has a long history of producing bamboo products. People use their splitting performance, mainly using the surface layer of bamboo barrels - green bark, bamboo weaving, bamboo utilization rate is only about 30%. In 1979, Hunan Province started to develop bamboo building materials and put it into mass production in 1980. At that time, bamboo mats were used to make bamboo mats that were discarded from the production of bamboo utensils. Bamboo plywood was made by laminating, sizing, and hot-pressing techniques. The products were soon popularized in the construction market and later expanded to the packaging boards for mechanical products. Furniture partitions and rice farming machines, windmills, barns, etc. In 1983, a bamboo glue form used for concrete was developed by the Hunan Bamboo Plywood Factory. After several tests, they used the bamboo processing process of the waste into a bamboo curtain as a skeleton material, and the original bamboo mat composite hot pressing, then successfully developed a concrete bamboo glue template. Its main performance is:
