木灰比对水泥纤维板吸声性能与导热性能的影响

Effect of fiber/cement ratio on acoustic performance and thermal property of cement fiberboard

随着社会的发展,人们生活质量的不断提高,对居住声环境及保温要求也越来越高,因此改善声环境、提高居住的保温性能越来越引起大家的重视。本文研究植物纤维/水泥比(木灰比)对于水泥纤维板吸声系数和导热系数的影响。研究发现,水泥纤维板的导热系数随木灰比的增大而逐渐减小;水泥纤维板的吸声系数基本接近于1,随木灰比的变化对其影响不大,吸声性能好。

With the development of social and the level of people s hve,people have attached more and more importance to improve sound environment and heat conduction of the residence.This paper research effect of fiber/cement ratios on sound absorbtion coefficient and heat conduction coefficient of cement fiberboard.Though research with the increase of fiber/cement ratio heat conduction property of cement fiberboard decreases,but its sound—absorbing coefficient unchange basically.
