Abstract:

In this paper, 216 different groups of bamboo charcoal were collected from 18 factories in Zhejiang Province, and their respective water content, density, ash percent,volatility, the charcoal contained percent,the burning hot value, resistivity, conductance and pH value were measured according to the reference national standard. Applying probability density function, principal component analysis and analysis of variance to analyze relations among bamboo charcoal physic-chemical properties with the help of Matlab, the results shows that bamboo charcoal physic-chemical properties are significantly different among factories but not interior factory; that bamboo charcoal physic-chemical properties are mild significant. The factors loading matrix show that vaporized percent, ash percent and the burning hot value, pH value are opposite sign so they are negative but positive between the charcoal contained percent and the burning hot value, pH value. The factors loading matrix are positive between density, ash percent and resistivity of bamboo charcoal but negative between density, ash percent and resistivity.

Key words: bamboo charcoal, physic-chemical properties, test, analysis
