Climatic influences on the building materials properties based on wood-polymer compositions

The work is devoted to the assessment of the influence of climatic influences on wood-polymer composites (DPC), which are actively used for the production of building materials. In particular, terraced boards and other construction materials are made from them. Since terraced boards are often used outdoors, it is necessary to study in detail the effect of moisture on the change in color of products, their water permeability, the ability to withstand UV radiation, etc. In the work, terraced boards produced by the domestic company Savewood are investigated. The matrix polymer was polyvinyl chloride (PVC). The studies were accompanied by theoretic studies of water permeability. The relationships describing water permeability of polymers are given. These ratios include the parameters of the chemical structure of polymers. Experiments on the influence of climatic effects are performed with the help of modern instruments at positive and negative temperatures (paper)
