WPC Product Water Absorption Expansion Solution
The comprehensive performance of wood plastic composite decking materials is very excellent, and more and more varieties of wpc materials are used in outdoor buildings and landscape, and the quantity is also increasing. With the continuous progress of manufacturing technology and technology, the appearance quality of products has been greatly improved. However, during the rainy season, the wpc absorbs water and expands, and the wpc material produces slight creep elongation, which cannot be recovered. The creep elongation and superposition are produced periodically with the alternation of dry and wet periods. As the wood in the wpc reaches the possible water-absorbing expansion limit and the binding effect of polymer materials, the increment of water-absorbing expansion creep elongation decreases to zero and reaches the creel limit. wpc outdoor decking material creep is temperature stress creep superposition and swell creep the comprehensive result of a long wpc ends are fixed constraint, along with a variety of wpc material creep superposition, beautiful linear materials when built, gradually apparent bending; And after a number of heat and cold alternation, the size is basically stable and the bending degree is no longer increased.
