Wood-Plastic Composites Weathering Quality Issues

摘要

Recent research sheds light on the complex interactions between ingredients in wood composites that affect weatherability,color loss,and resistance to moisture,mold,and aging.Exterior wood-fiber composites like decks and rails haven't lived up to some of the early claims of long,maintenance-free life.In fact,composite decks with high wood loadings can shrink,expand,stain,warp,split,and fade much like natural wood.They can also grow mold and sprout mushrooms,be eroded by water,and eaten by termites.
