622 Vol.27 No.4 XUE Ping et al: Effect of Photostablizers on Surface Color and Mechanical as ultraviolet absorbers UVA and hindered amine light stabilizers HALS were proved great effective to improve weathering performance of WPC 13-15 . Others have also shown that pigments are also able to prevent
Wood composite decking with groove surface . Wood plastic composite WPC made of 50% wood fiber and 50% PP,PE or PVC resin together with specialized ingredients, imported pigment, and anti-UV material.
123S , CIBA blue pigment IRGALITE , and their combinations. Two surface roughness parameters average roughness Ra and maximum roughness Rmax used to evaluate surface characteristics of the samples showed that overall properties of WPC panels, namely using right size of material, optimum
The WPC process is unrivalled in treating engine parts and other surfaces that have contact points of friction. WPC is superior because it is not a coating; it is a permanent surface treatment that reduces friction while strengthening the part.
In addition, short-chain hydrocarbons migrate to the surface and lignin photo-bleaching leads to the change of lightness Jabarin and Lofgren 1994; Muasher and Sain 2006 . The lightness of the Ctrl, WPC-U, and WPC-T increased, while the lightness of WPC-C and WPC-T-C decreased.
1 Dec 2014 further reducing the degradation of the surface of the WPC, the pigments Keywords: wood-plastic composites, ultraviolet light, weathering. Investigations on ageing of wood-plastic composites for outdoor.
TECHINICAL SPECIFICATIONS DATA SHEET: WPC the surface is roughened by brushing. Due to this, the WPC-deck acts in its smallest particles, the open wooden fibers on the surface, During production, organic colour pigments and UV protection measures are built in. Slight color changes and shades are desired, and emphasize the natural wooden

Weathering results in the destruction of the WPC surface Fig. 20.10 . Wood particles exposed at the surface absorb water and swell. In addition, the plastic matrix cracks upon UV exposure. In combination, the result is a flaky, cracked surface. As WPCs weather, the surface chemistry also changes. Pigments, ultraviolet absorbers,
Laboratory and environmental decay of wood plastic composite boards: flexural properties pigments, mineral fillers, coupling agents, biocides and stabilizers Gardner and Murdock 2010, Lam 2010, Hanawalt 2012 . Some researchers from industry taken for each WPC surface of interest and analyzed, including
WPC during exposure was caused by degradation of both wood and plastic. Darker color pigments as additives im-proved the color stability of WPC; however, chalking on the surfaces still occurred. The color stability of WPC was improved by application of exterior coatings. Prewea-thering of WPC before coatings were applied increased
