Plastics - thermoset moulding compounds - composites and reinforcement fibres - preparation of specimens for determining the anisotropy of the properties of compression moulding composites 塑料.热模化合物.复合和增强纤维.压模化合物的向异性能测定用试样制备
In the compression moulding technology , preheat and prepressing procedures are added to improve the flowability of the bond and physical and mechanical properties of the product 在压缩模塑工艺中,增加预热、预压工序,提高粘合剂的流动性和产品的物理机械性能。
At first , the bonded magnet has been produced at varied technological conditions . then the influences of varied technological conditions , such as species and quantity of coupling agent , species and quantity of agglomerant , process of compression moulding and solidification process on magnetic property and compression strength of bonded magnet have been analysis by means of apparatus for measuring magnetic property and compression strength 首先,在不同工艺条件下制备出粘结磁体,然后利用磁性能测试仪、力学性能测试设备等测试手段,分析了偶联剂的类型及其用量、粘结剂的类型及其用量、模压工艺和固化工艺等因素对铁氧体粘结磁体磁性能及力学性能的影响。
