NFM Welding Engineers manufactures the TEM Series of co-rotating, intermeshing compounding twin-screw extrusion systems. The company says that this offers a high torque-per-free volume and high screw speed. The TEM Series can process a wide variety of plastics compounds including wood-plastic composite materials, such as PVC, polyethylene and polypropylene, in combination with most woods including pine, maple and oak. NFM adds that the system requires no pre-drying or pre-mixing, saving capital equipment costs, plant space and maintenance. End product can either be directly extruded or pelletized for direct feed to a single screw system. The TEM Series is available in models from 26–240 mm.This is a short news story only.

The use of wood-plastic composites is growing rapidly, as consumers experience their advantages over wood including low or no routine maintenance and no cracking, warping or splintering. Additive use is growing as wood-plastic composites penetrate new markets with more stringent performance requirements and as interest in long-term stability of composite products increases. While profile extrusion is used for the biggest portion of the market, in decking boards, injection moulding is finding a place as well. Foaming of both extruded and injection moulded parts is of growing interest. Jennifer Markarian reports for Plastics Additives & Compounding. 相似文献

Compounding of wood and natural fibre-plastic composites continues grow at a pace that significantly exceeds that of the general plastics industry- both in North America and now in Europe also. Jennifer Markarian reviews the international market for wood-plastic composites and discusses some of the issues for both captive compounding and compounded product. 相似文献

PVC木塑复合材料热解动力学 总被引:2,自引:0,他引:2
将木粉按一定比例添加到PVC中得到复合材料,通过热重分析研究复合材料在空气、N2气氛下不同升温速率时的热解行为。通过Doyle和Tang method法计算了木塑材料的降解活化能。利用活化能分布函数,分析了复合材料在热解、燃烧过程中不同阶段的反应活性变化规律。研究表明,热解过程可分为3个阶段,230~360℃为第一失重阶段,360~430℃为稳定阶段,430~580℃为第二失重阶段。升温速率及反应气氛对热解过程有显著影响。由分布活化能模型计算表明,其热解动力学为一级反应,两个失重阶段的活化能分别为220kJ·mol-1和139kJ·mol-1,反应活性随失重率的增加而减少。 相似文献
