| WPC studies Species |
WPC product moisture performance is very good. Especially when compared to wood. But over time, the moisture resistance will be discounted. Currently, the laboratory water circulation commercial WPC boards, wet / dry cycle studies are underway. The boards were composed of 60% wood chips, 40% of high-density polyethylene (HDPE) composition. The results showed that, after each cycle of water, the water content of the sheet will have a certain degree of increase. After four cycles after its water content has reached 2.6%. The results showed that, after experiencing water cycle test, void volume between wood and plastic increasedBarefoot Friendly Wpc Floor With Good Price.
"Constitutes WPC products is very complex" Atlas Material Testing Technology, said two senior advisers AllenZeilnik "polymer fibers and bio-degradation mechanism has its own separate" "Because of the degradation of the polymer composite surface, the fiber is located end, so moisture will be absorbed deep into the interior through the surface of the material. "he explains. Like a leaky faucet this problem continues to worsen over time. Since the fibers absorb moisture and sustained expansion, leaving voids after drying. This will lead to more complex materials inside the product to absorb moisture, so a vicious cycle. These voids, while providing a very useful environment for the growth of microorganisms, fungi and moldslow maintenance WPC terrace deck.
Best outdoor floor materials supplierSince the passage of moisture is absorbed into the wood fibers inside the composite material, the simplest way is to reduce the amount of wood filler. Gardner said that many commercial plate production by adding 60% to 65% of the wood filler. "Sometimes even the manufacturer added too much wood raw material."
Another product to prevent mildew WPC ways to use other types of wood in the production process. Test showed that there is a fungus, white-rot fungus, more like wood. The hardwood is WPC products are a major source of wood flour. Workaround You can use western red cedar wood as a substitute. |
