Abstract

The features of the adhesive interaction of spores of various types of mold fungi deposited in a stationary air environment with polymeric materials are investigated. It is shown that regardless of the type of material, its angle of inclination, and the type of fungus, all spores that have reached the polymer surface remain on it. The location of the sample relative to the source of spore propagation and the mechanism of their supply to the surface determine the number of spores retained on the material, characterizing the microbiological component of the air environment (the content and specific consumption of fungal spores in it). An algorithm for estimating this characteristic is proposed. It is advisable to take the research results into account when developing methods for testing the resistance of polymer materials to infection and damage by biodestructor fungi.

霉菌孢子在空气中沉积过程中与高分子材料的粘附性
研究了沉积在固定空气环境中的各种霉菌孢子与高分子材料的粘附相互作用的特点。结果表明,无论材料的类型、倾斜角度和真菌的类型如何,所有到达聚合物表面的孢子都会留在聚合物表面。样品相对于孢子繁殖源的位置以及它们向表面供应的机制决定了材料上保留的孢子数量,表征了空气环境的微生物成分(其中真菌孢子的含量和特定消耗)。提出了一种估计该特性的算法。在开发测试高分子材料对生物破坏性真菌感染和破坏的抗性的方法时,应考虑到这些研究结果。
