Below physiological structure and the molecular organization content contrasting data of Cluster Bamboo (for imperial bamboo) and Scattered bamboos (for bamboo):
1, imperial bamboo former bamboo water ratio is high, about exceeds bamboo 15 ~ 20%;
2, imperial bamboo former bamboo sugar degree is high, about exceeds bamboo 5 ~ 10%;
3, the former bamboo of imperial bamboo containing protein and amount of starch high, about exceed bamboo 5 ~ 10%;
4, the former bamboo bamboo fibers of imperial bamboo is thick, about exceeds bamboo 45 ~ 50%;
5, imperial bamboo bamboo fibers alkalinity is less than about bamboo 5 ~ 15%;
6, imperial bamboo ring belongs to continuous shape mesh screen structure, and ring thickness about exceeds bamboo 100 ~ 200%;
7, imperial bamboo former bamboo bamboo assists position fibre density low, is less than about bamboo 25 ~ 40%;
8, bamboo hardness is about the twice of imperial bamboo hardness;
9, imperial bamboo about exceeds bamboo 5 ~ 10% containing plum acid amount height;
10, imperial bamboo and the gluing synthesis performance test of bamboo; With identical pvac tackiness agent, use gummed pressure viscose glue closure bamboo and the bamboo respectively that the bamboo chip of equal volume is equal.Bamboo bears the fibre breakage only having 78% more than 10 newton/square millimeter pressure, but Cluster Bamboo only reaches the fibre breakage that 7 newton/square millimeter pressure just has 100%.
