摘要

摘要本文试图评估将废弃纤维制成的非织造布用于覆面板的可能性。为此，测试了羊毛和聚丙烯非织造布的单位面积质量、特征开口尺寸以及最大强度下的纵向和横向伸长率。在水泥板和石膏板厚度的中间放置非编织物，并对其进行密度、导热系数λ和弯曲强度测试。测定了不同性能的非织造布对复合材料性能的影响。结果表明，羊毛非织造布对导热系数的影响最大。石膏砂浆对非织造布具有较好的亲和性。对板的弯曲强度影响最大的是聚酯无纺布，其单位面积质量最低，特征开口尺寸最大。

Testing the Properties of Cement and Gypsum Boards Reinforced with Nonwoven Fabrics Made of Waste and Recycled Fibres

Abstract The article attempts to assess the possibility of using non-woven fabrics made of waste fibers in cladding panels. For this purpose, woolen and polypropylene nonwovens were tested for mass per unit area, characteristic opening size, and lengthwise and crosswise elongation at maximum strength. Non-woven fabrics were placed in the middle of the thickness of cement and gypsum boards and subjected to tests of density, thermal conductivity coefficient λ, and bending strength. The influence of individual nonwoven fabrics with different properties on the properties of the finished composite was determined. It was found that wool nonwoven fabrics had the best effect on the thermal conductivity coefficient. A better affinity for nonwoven fabrics was shown by gypsum mortar. The best influence on the bending strength of the panels had polyester non-woven fabrics with the lowest mass per unit area and the largest characteristic opening size.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
