The paper presents the manufacturing technology for a material obtained from glass fiber waste, quartz sand, and polyester binder, used for ornamental building plates. The composite has a cover surface that ensures protection of the material from environment attacks and a structural material that can be subjected to chemical degradation. The mechanical properties of the obtained material were experimentally investigated through compressive mechanical tests. To observe the material's behavior in contact with external agents (rain or acid rain, due to environmental pollution), analyses were performed in laboratory conditions. An investigation on the effects of chemical attack substances was conducted. SEM and macroscopic analyses were performed, and the surface roughness was determined for each sample area. The obtained results were statistically analyzed and showed that there is no significant difference between the surface roughness for treated and untreated samples. Furthermore, the surfaces were analyzed by X-ray diffraction and mineralogical optical microscopy in polarized light with crossed nicols. It was observed that rainwater does not affect the plate structure even if the plates are used in high-pollution environments. The material is suitable for exterior building walls from the point of view of chemical attack and resistance.
本文介绍了一种由玻璃纤维废料、石英砂和聚酯粘结剂制成的用于建筑装饰板材的材料的制造技术。该复合材料有一个覆盖表面，可确保材料免受环境侵蚀，还有一种可能会发生化学降解的结构材料。通过压缩力学试验对所得材料的力学性能进行了实验研究。为了观察材料与外部介质（由于环境污染造成的雨水或酸雨）接触时的行为，在实验室条件下进行了分析。开展了关于化学侵蚀物质影响的研究。进行了扫描电子显微镜（SEM）和宏观分析，并测定了每个样品区域的表面粗糙度。对所得结果进行了统计分析，结果表明，处理过的样品和未处理的样品在表面粗糙度方面没有显著差异。此外，还通过X射线衍射以及在正交偏光镜下的矿物学光学显微镜对表面进行了分析。结果发现，即使板材用于高污染环境，雨水也不会影响板材结构。从耐化学侵蚀的角度来看，该材料适用于建筑外墙。
