Since 2006, the National WPC Standards Committee has planned work on the development of 'ecological wood' industry standards and has been completed by the end of 2012. It is expected to be announced to the public in early 2013. As a participant in the formulation of the national WPC standard, ecological wood is named as 'Wood-plastic Composite Profile' by China WPC Standards Association.price of tongue and groove porch floor The designation at the national level has stated that 'ecological wood' is a composite of wood and plastic and a profile
. So what is the relationship between wood and ecological wood? Wood-plastic refers to the use of polyethylene, polypropylene and polyvinyl chloride, instead of the usual resin adhesive (containing formaldehyde and other harmful substances),build a removable wooden privacy fence panel and more than 35% -70% of wood flour, rice husk, straw and other waste plant fibers mixed New wood materials, and then by extrusion, molding, injection molding and other plastic processing technology to produce the plate or profile. The ecological wood is the use of pvc (that is,
vinyl chloride in the polymerization initiator under the use of thermoplastic resin) and wood flour, reinforcing agent, calcium powder, blowing agent polymerization thermoplastic extrusion materials. So ecological wood is a kind of wood. books on how to build decksOne of the earliest wood-plastic materials was classified as eco-wood due to the difference between foamed and non-foamed. The other material is now called pe-type eco-wood. Therefore, ecological wood is divided into: pe ecological wood and pvc ecological wood, and all belong to wood.
