Description

一种多点式雪地靴保暖性能测试装置及方法
技术领域
本发明涉及一种多点式雪地靴保暖性能测试装置及方法。
背景技术
如今已遍布全球街头的雪地靴有50%以上出自中国的工厂。雪地靴的保暖性能是雪地靴诸性能中重要的性能,尤其是在一些比较寒冷的国家和地区,消费者要求其雪地靴要具有良好的保暖性能。如果销往寒冷地区的成鞋保暖性能比较差,该产品的销售将受到极大影响,严重影响企业发展。在雪地靴的设计、原材料的采购、打样和到成品的各个环节,考虑和关注保暖性是保证不丢失客户,保持终端市场占有率的一个重要方面,所以,对雪地靴的材料和成品的保暖性能进行检测就显得非常必要了。
目前,雪地靴已占据冬季鞋靴类市场的大半江山,但生产企业基本上是在按照QB/T 1002-2005《皮鞋》、QB/T 2955-2008《休闲鞋》或企业自己制定的企业标准进行生产加工和检测。由于《皮鞋》和《休闲鞋》标准中并未涉及保暖性测试这个项目,从我们日常检测来看,一般企业制定的企业标准也都未把保暖性这个项目列入。可以发现,雪地靴最关键,最吸引人,也是决定购买的一个最重要的因素-保暖性,但我们并不知道真实的检测数据。仅有的是,我们所认为的雪地靴保暖,来自于用皮毛一体的澳洲羔羊毛皮制作的雪地靴的保暖性,关于其他材料生产的雪地靴的保暖性无从得知。所以生产企业和检测检测机构迫切需要适合雪地靴保暖性的测试仪器。
另外,特别是由于目前还没有针对雪地靴的保暖性有强制要求,一些雪地靴生产厂家趁机鱼龙混杂,用各种不符合要求的产品蒙骗消费者。消费者为了维护权益,要求对雪地靴的保暖性进行检测,而我们的仪器、标准却远远落后于市场需求,无法满足各方利益者的要求。如现有的鞋类产品保暖性能测试仪,数据离散性大、数据差距大,传热系数相差4-5倍。测试环境相差大,造成数据的不准确。各个企业生产的仪器所使用的方法、标准不严格,不统一。有的企业生产的仪器结构不合理,造成操作不方便,还有的仪器甚至靠手动手调等等问题,都不能适应雪地靴的保暖性测试。也就渴望能有仪器能补上现有仪器存在的不足。
发明内容

4、将6个测试探头置入鞋腔内,分别放置在前掌上帮面、前掌内底、第一跖趾关节、第五跖趾关节、后跟里中心下沿点、外踝骨中心下沿点;1个测试探头置入低温试验箱内;1个测试探头放在测试实验室内;
5、开启测试,温度记录仪自动记录10分钟温度的降低;
6、试验结束后,查看显示屏试验结果界面,记录各个测试点的测试结果。
进一步,在测试前将雪地靴在(23±2)℃、相对湿度(50±5)%的环境下调节24h,多点式雪地靴保暖性能测试装置也应在同样的环境下调节,并在该环境下试验。
进一步,温度记录仪记录的测试数据包括记录鞋腔内各个部位1min的降温、记录10min鞋腔内各个部位的温度降低、计算6个部位温度降低的平均值、记录低温箱温度和测试环境温度。各数据均用℃表示,精确到0.1℃。
