由于树脂自硬砂具有强度高,尺寸精确,溃散性能好,易于实现机械化、自动化等一系列的优点,在我国应用范围目前逐步扩大。树脂自硬砂有它本身的技术特点和性能要求,其中最重要的性能之一是与终强度相联系的可使时间。它不仅取决于树脂、催化剂等性能,而且直接与混砂时间和混砂质量有关,为此华中工学院根据树脂自硬砂的特点,研究设计了一种具有自清理粘砂能力、适用于中小型芯砂生产的间歇式高效混砂机,在荆门通用机械厂的
Since the resin has a series of advantages of high strength, precise size, good collapsibility, easy mechanization and automation, the application scope of our resin is gradually expanding. Resin hard sand has its own technical characteristics and performance requirements, one of the most important performance is associated with the final strength can make time. It not only depends on the properties of resin and catalyst, but also directly relates to the time of sand mixing and the quality of sand mixing. Therefore, Huazhong Institute of Technology, according to the characteristics of resin self-hardening sand, studies and designs a self-cleaning sticking sand capacity, Small core sand production batch efficient mixer, Jingmen General Machinery Factory
