轻质菱苦土木丝板吸声导热性能的工艺影响因素

Study on the Sound Absorption and Thermal Conductivity Properties of Low Density MagnesiaBonded Wood Wool Panel

摘要: 通过正交试验，研究灰木比、密度、板材厚度和添加剂4个因素对木丝板的吸声系数和导热系数的影响。结果表明：当灰木比为2.0，密度为045g/cm3，厚度为16mm和添加剂为NO.3型时，木丝板的吸声系数最佳；当密度为045g/cm3，厚度为16mm，添加剂为NO.2型时，木丝板的导热系数最佳。

Abstract: The effects of magnesia ratio to wood, the density, thickness and additive on the sound absorption coefficient and thermal conductivity of the low density magnesiabonded wood wool panel were studied with orthogonal experiment. The results showed that the sound absorption property was best when the ratio of magnesia to wood was 2, the density was 045g/cm3, and the thickness of the panel was 16mm, and the No.3 additive was used. The best thermal conductivity of the panel could be obtained when the density was 045g/cm3, the thickness was 16 mm, and still the No.2 additive was applied.
