<p> Lignin provides strength and durability for the timber, depends largely on the strength of wood lignin, lignin is the plant material, after acid hydrolysis of the residues left, wood matrix polymer to an infiltration macromolecules, largely reducing the chance of cellulose decomposing bacteria, higher softwood lignin content. <a href="http://www.woodfloorprice.com/wood-floor-knowledge/2558.html">composite door manufacturer malaysia</a> Typically flour particles showed a fragmented softwood, hardwood of cylindrical. Although lignin (wpc) mechanical properties of wood plays a major role, but itself has some adverse effects. Lignin is a photosensitive material, UV light degradation will occur, which is wood and wood (WPC) materials mainly due to fading under UV light, lignin will turn from brown to gray. Make the wood lignin (wpc) material properties weakened because in the process of flammable and release carbon dioxide, can reduce the density of the product, in outdoor exposure will accelerate fading wood materials. </p> <p>Hemicellulose in the process is flammable, release mainly VOC, wood materials can reduce the density of the product, enabling the product to generate steam explosion in the production process, mainly because of momentary pressure and moisture throughout the wet wood particles boiling sharply. Wood fiber aspect ratio of WPC (wpc) material properties has some influence, the larger the aspect ratio the better the flexural properties, because more fiber in the melt flow direction. Extrusion process cause of aspect ratio is lowered. The larger the aspect ratio, the better the fluidity of the melt, <a href="http://www.environmentallyfriendlyflooring.com/project/4772.html">interlocking tile flooring tile wood plastic composite tile</a> can reduce mold shrinkage of the material. In Wood (wpc) material, cellulose content, the more faded the more serious, but the material will increase the oxidation resistance, hot melt viscosity will increase, and the smaller the particle size of the wood flour, the higher the viscosity. </p> |
