Abstract

Methods are proposed which permit estimating bioresistance of protective materials against denitrifying hydrocarbon-oxidizing and sulphate-reducing bacteria-destructors of coatings in laboratory conditions. The methods are based on the quantitative determination of bacteria growth in presence of coatings as the only source of hydrocarbon. Besides, attention is given to changes of certain indices of physico-mechanical properties of coatings: breaking strength and adhesion strength for coatings from polymeric bands, softening and expansion temperature for mastic materials.

摘要

提出了一些方法，这些方法能够在实验室条件下评估防护材料对涂层反硝化烃氧化菌和硫酸盐还原菌破坏作用的生物抗性。这些方法基于在涂层作为唯一碳源存在的情况下对细菌生长进行定量测定。此外，还关注涂层某些物理机械性能指标的变化：聚合物带涂层的断裂强度和附着强度，胶泥材料的软化温度和膨胀温度。
