55度杯被曝无相变材料:只是带夹层水的保温杯

55度杯被曝无相变材料:只是带夹层水的保温杯

腾讯数码讯(李珅)知乎网友“野合菌”对时下非常热门的55度杯进行了拆解,发现其导热原理非常简单,并没有使用官方所宣称的微米级相变材料,充其量只能算是带夹层水的保温杯

55度杯是LKK洛可可设计集团下属公司推出的产品,名为快速降温杯,倒入开水摇1分钟,杯内水温可降至55度左右。有网友猜测,55度杯采用的是“三水醋酸钠、十二水磷酸1氢钠和明胶”等作为导热材料,原理与暖宝宝等类似。

官方曾对此表示否认,并声称这是不法商贩仿制55度杯所采取的做法,正品55度杯具有导热层、微米相变材料和隔热层三层。导热层为不锈钢材质,可将杯子里热水的热量快速传递到微米级的相变材料中,通过微米级的相变材料快速吸热,实现降温功能。

“野合菌”在拆解时发现,55度容积为280ml,其内胆内部具有超过270ml的橙褐色悬浊液,单独对悬浊液进行加热,温度会从室温直线上升至100摄氏度,并不存在升温减缓的曲线,加热过程中悬浮颗粒也没有发生固体到液体的转变,也就是说不存在所谓相变。

此外,每100ml悬浊液经过离心分离可提取约0.05g固体,该固体加热至400摄氏度不分解,确属微米颗粒,不溶于水、1N盐酸、1N氢氧化钠和丙酮。

因此,“野合菌”断定,55度杯所采用的储热方式只是最原始水比热容储热,在使用过程中不会发生所谓的相位变化,“野合菌”还表示,55度杯所采用的降温材料比廉价的三水合醋酸钠更为廉价。

另外信息显示为美国西北大学博士的网友“成楚旸”也表示,55度杯其实就是个里面带夹层水的保温杯,夹层的冷水实现快速降温,温度变化计算过程为(20+90)/2=55,外层保温材料让降温曲线出现一个较长的平台期,升温效果也比较坑爹,温度变化计算过程为(50+20)/2=35。

从官方页面中我们可以看到,55度杯倒入开水并摇1分钟,水温可降至55摄氏度,此时如倒入常温水,摇1分钟,室温可升至37摄氏度左右,而如果继续倒入开水,需半小时后才能降至55摄氏度,并未对直接倒入常温水的情况进行说明。
