摘要：参考相关国家标准,对浙江省18家竹炭厂216组竹片炭的含水率、密度、灰分、挥发分、固定炭含量、燃烧热值、电阻率和pH值等理化性能进行测试。应用Matlab软件,采用概率密度分布方程、主分量分析和方差分析方法对竹炭的理化性能进行分析。结果表明:不同的竹炭生产厂家生产的竹炭理化性能差异极显著,而同一厂家生产的竹炭理化性能差异不显著;竹炭的理化性能相关性不紧密;挥发分和灰分与热值和pH值因子负荷量为异号,呈负相关;固定炭与热值和pH值因子负荷量为同号,呈正相关;灰分和密度与电阻因子负荷量为异号,呈负相关;灰分和密度与电导率因子负荷量为同号,呈正相关。
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.
