<p>Separate plastic and wood have its shortcomings, and put them together is what we call wood-plastic composite material, it not only has good elastic modulus, but also can achieve anti-aging, anti-static, flame retardant, etc. special requirements. After years of scientific and technological personnel efforts in the support of the National Science and Technology Support Program, the modified wood-plastic composite materials technology has been great innovation and achieved gratifying progress.</p> <p>With the growing shortage of wood resources, prices are getting higher and higher, so the most recent wood-plastic composite materials to biological resources - plant fiber (crop waste) as raw materials. China is a big agricultural country, crop waste is very rich. According to the Ministry of Agriculture statistics, in 2010 China's total straw reached 726 million tons. In the past a large number of residual straw was abandoned in the fields, or directly burned, and now can be used by waste modification technology, made of high-performance wood-plastic composite materials, widely used in construction, transportation, home appliances, automobiles, landscape and other fields.</p> <p>Dehumidification is an important part, dehumidification is not completely will seriously affect the performance of wood-plastic products. The traditional method of a dehumidification can not meet the technological requirements of wood-plastic products. The new technology to take high-speed mixing of wood fiber dehumidification, dehumidification and dehumidification dehumidification three sections of dehumidification method to overcome the wood fiber is difficult to dehumidification of the bottleneck, so that the water content to meet the extrusion requirements.The effects of compatibilizer dosage, chain extender, PE type and compatibilizer on the structure and properties of the blends were investigated by using low-temperature solid-state heating technology. The low-temperature solid-phase extrusion and high temperature rapid reaction extrusion . Which reduces the hydrolysis and thermal degradation of the blend during the extrusion process. The polyolefin cross-linked structure forms a multi-network structure and limits the recrystallization of the polymer during the extrusion process. At the melting point of the polymer, the glass transition temperature above extrusion, close to the melting point of the polymer extrusion, significant energy savings.</p> <p>using composite or pvc decking for garden planters<br /> wpc wood and holly tongue and groove wall paneling<br /> composite wood rooftop pavers</p> |
