毕业论文的完成也意味着人生的一个舞台也落下了帷幕，也代表着马上就要走出校门去迎接下一个阶段的人生，角色也即将发生变化，大学四年看似匆匆，但是其中收获却是满满，有老师的谆谆教诲、辅导员的声声关切、同学的温暖陪伴，让本来看上去枯燥的学习变得有趣起来。这四年令我受益匪浅，从懵懂少年蜕变成为能够独当一面的“大人”。
这些都不得不感谢学校提供这样的良好的学习环境，老师们的细心教导，特别是指导老师的指导使得论文能够如期顺利完成。虽然离别将至，但是学校和老师们永远是我的第二故乡，永远不会忘记。并且也希望南京林业大学能够蒸蒸日上，老师学生们都能顺利地在这里生活学习。从这里走出来的学生们都能抬头挺胸，为此而自豪。
摘 要
塑木材料是近些年来才逐渐发展起来的一种新型环保绿色的复合材料，它兼备木材与塑料的抗冲击、高硬度等力学性能以及抗腐蚀、防水等化学性能优势，生产起来较为容易，产量高，易于产业化，符合当下全球资源匮乏的形势，能够满足人们的日益增大的使用需求，是良好的代替木材的新型材料。PVC塑木是最常用的塑木之一，性能十分优异，原料价格便宜、来源也十分广泛，拥有广大的国内外市场前景，其中具有相当的商业价值。本文拟设计生产一条PVC塑木地板材料的生产线，采用挤出成型的方式来生产年产量高达5000吨的PVC塑木地板，首先对于PVC塑木的配方进行了多样化的设计，设计了详细生产过程的工艺流程方案，对生产车间的设计原则以及车间安全守则进行了阐述并且具体设计了车间的平面设计图，然后选择适当的主设备机器以及配套的辅机选择，确定其数量。之后需要计算5000吨年产量的目标产物的物料守恒。最后，作为绿色材料，对于生产的环保和可持续发展问题也必须要慎重解决，妥善处理生产废料以及按照国家有关处理标准排放废料也是本次设计所要考虑的问题之一。综上所述，从整体上对于车间生产线的方方面面进行详细的设计。

Annual output of 5, 000 tons of PVC plastic wood landProduct Line Design
ABSTRACT
Plastic wood material is a gradually developed in recent years of a new type of environmental protection green composite material , it has the impact resistance of wood and plastic and high hardness mechanical properties and corrosion resistance , waterproof chemical performance advantages , is easy to produce , high yield , easy to industrialization , meet the current lack of global resources , can meet peoples increasing demand for use , is a good new material instead of wood .PVC plastic wood is one of the most commonly used plastic wood , very excellent performance , cheap raw materials prices , and very wide sources , has a broad domestic and foreign market prospects , which has considerable commercial value .This posed in this design To produce a production line of PVC plastic wood flooring materials, extrusion molding is used to produce PVC plastic wood flooring with an annual output of up to 5000 tons. Firstly, the formula of PVC plastic wood is diversified, the process flow scheme of detailed production process is designed. After that, it is necessary to calculate the material conservation of the target product with an annual output of 5000 tons. Finally, as a green material, environmentally friendly and sustainable The problem of continuous development must also be carefully solved, and the proper treatment of production waste and the discharge of waste according to the relevant national standards are also one of the problems to be considered in this design. To sum up, from the overall workshop production line for all aspects of the detailed design.
Key words：conservation of materials in environmental protection extrusion process
