Study On The Decay Resistance Property And The Choice Of Preservatives Of Bamboo

Using Moso bamboo(Phyllostachys pubescens Mazel exh.de Lebaie)as raw material and white rot and brown rot as main fungi, this paper studies the interior natural decay resistance of Moso bamboo; Using CCA as standard and choosing some environment-friendly preservatives to treat bamboo, this paper also studies that the change of decay resistance of bamboo, the leachibility of preservatives, the fluency of preservatives treatment on the mechanical property of bamboo, thus chooses bamboo preservatives used for different environment. The result shows:(1)The decay resistance property to brown rot of bamboo is higher than to white rot, the weight lose rate to white rot is 19.88%, but to brown rot is 5.86%.(2)There are 15 preservatives chosen to test interior decay resistance, these preservatives have good effect except DDAC. And, there are 19 preservatives for leaching test, ACQ-P, ACQ-B, ACQ-D and the copper triazole formulations (CuAz) have high copper fixation rate, but the organic acid salts preservatives are not good.(3)At adequate retention level, ACQ-P, ACQ-B, ACQ-D, CuAz formulations and the organic acid salts preservatives can be used for interior and exterior non-tuching soil environment; Expect the organic acid salts preservatives, the other above can be chosen as exterior preservatives, and their field decay resistance should further study.(4)The SAS system analysis result shows that ACQ and CuAz treatment has no significant fluency on MOE and MOR of bamboo.
