稻草板封端机封边部分设计及动态演示 摘 要 自古以来木材就与人类的生活息息相关，也是当今四大材料(钢材、水泥、塑料、木材)中唯一可再生利用的绿色、环保材料。木材不仅具有优良的力学性能，还具有许多功能性。首先，木材的纹理给人以亲切、贴近自然、高雅的感觉。其次，木材是一种多孔材料，可以自动调节室内的湿度，研究表明：长期生活在木质环境中不仅对人的身体有很大益处，还能延长人的寿命。最后，木材还是热的不良导体，用木质材料制造的房屋具有冬暖夏凉的功能。 尽管木材由于其本身的优良特性，深受人们喜爱;但我国木材资源严重短缺，因此不得不寻找其他资源进行代替，因此，稻草板成为了研究的对象，因为我国是一个农业大国，每年生产的农作物秸秆就有7亿吨，因此，能对稻草秸秆进行合理利用是当务之急，因此，科学工作者研究了稻草板生产线，本次设计就是对稻草板生产线的封端机的封边部分进行设计，并运用UG软件对进行动画演示 关键词　封边机UG；动画演示 Abstract The straw board that act as a kind of new environmental protection building materials and brick substitutes have been developed in recent years. It is effectively way for plentiful satisfy requiremenlt to design the efficient production line. There are lots of difference between extrusion molding and flat-press molding, and that produce hollow rice-straw particle board was feasible proved by the theory and the practice. And it has been applied for the Nation Patent. It breaks through the difficult problem of that it cant produce rice-straw particle board with Urea Formaldehyde resin at first time. It confirms the following hot-press technicality. The hot-press temperature is 160degrees centigrade. The board per meter cost two point seven minute to come out from machine; the moisture of the raw material is form three percent to four percent. The resin accession quantity is four point five percent. The ratio of quality of rice-straw and wood is seven to three. The modulus of rapture of the board can arrive the request of the . At the same time the modulus of rapture of the board was machined secondly in the factory is 7.09MPa, and the out intensity of the board, and both of them can arrive the request of the. The dissociation formaldehyde quantity of the board is three milligram per one hundred gram of board measured by Nanjing Wood-based Panels Testing Center of the forestry Administration of China. It shows that the rice-straw can reduce the dissociation formaldehyde quantity in the board. The heat conduction value of the hollow rice-straw particle
