摘要 纸张耐折度是纸张性能的一项重要指标。纸张耐折度测定仪是为了测量纸张的耐折度而设计的测定仪器。为了更好的利用纸张，我们需要对纸张的性能进行衡量，而纸张的耐折度就是一个十分中要的衡量标准。比如，用于包装的纸制品（牛皮纸等）对于耐折度的需求就很高。相反在生活中常用的比如卫生纸，手纸等纸制品就不需要很高的耐折度。我们可以通过测量纸张的耐折度来衡量纸张的性能。所以纸张耐折度测定仪在纸张生产过程中具有十分重要的作用。所有厂商都需要通过这种测定仪来检验纸张性能是否合格。 此种测定仪在造纸行业中应用极广。本次设计的耐折度测定仪，主要应用于小型企业或工厂。 关键词:纸张；耐折度；测定 Abstract Paper foldi
