Study on Chemical Composition Changes of Poplus Used for Making Furniture Processed with Xylan After Decay

Abstract

Xylan extracted from corn cob is a new type of wood preservatives, which is not only harmless to humans and animals, but also no contaminating the environment. Through the extraction of corn cob xylan, anti-corrosion performance testing and compared with the CCA, the results show that: white rot fungus specimen weight loss rates were: 2.53% and CCA weight loss rates were 4.08%. In this paper, we carried out through cottonwoods of different states to measure, research and analyze the main chemical composition on their moisture content, benzene - alcohol extract content, lignin content and holocellulose content, which is for future improvement preservatives formulated to provide experimental data, through the comparison of chemical composition among different states of cottonwoods to find out how the effects of preservatives on cottonwood anticorrosive were. The experiments indicated that benzene-alcohol extractive contents of anticorrosion cottonwood and fresh cottonwood were close to 4.50% and 4.51%, while decayed cottonwood of benzene-alcohol content of drawn increased to 5.70%. Lignin contents of anticorrosion and fresh cottonwood were close: respectively, 22.10% and 22.55%, from 24.19% rotten cottonwood. The whole fiber content of Anticorrosion cottonwood, fresh cottonwood and decayed cottonwood were, respectively, 66.62%, 84.55% and 64.19%.
