暖手器的用法
首先(xian)充(chong)電,通(tong)電時(shi),人不得(de)離開,等(deng)待充(chong)電結束,指示(shi)燈自(zi)動熄滅,拔掉插頭和連接器(qi)后就(jiu)可(ke)以(yi)將暖(nuan)(nuan)手器(qi)裝入保溫袋內用于手部取暖(nuan)(nuan)了(le)。注(zhu)意通(tong)電時(shi)不要將電熱暖(nuan)(nuan)手器(qi)抱在懷中。
暖手器一般充電多久
暖手器是一種儲熱量大、保溫時間長的暖手用品,一般用專用的連接線接入220V電源6-10分鐘即可充電完畢,一次充電大概可以用幾個小時。具體充電時間和保溫時間根據暖手器品牌、質量、大小等因素有所差異,建議購買(mai)保溫時間長(chang)的優質暖手器。
暖手器發熱原理
暖手(shou)(shou)器(qi)發(fa)熱(re)原(yuan)理簡單(dan)來說是(shi)插上電(dian)(dian)源(yuan)后,通過(guo)電(dian)(dian)熱(re)元件(jian)(電(dian)(dian)熱(re)絲或PTC陶瓷元件(jian))來加熱(re)暖手(shou)(shou)器(qi)里的過(guo)飽和溶(rong)液(ye),使它的結(jie)晶(jing)溶(rong)解,大約5-8分鐘此過(guo)程結(jie)束;斷電(dian)(dian)以后,電(dian)(dian)熱(re)暖手(shou)(shou)器(qi)的過(guo)飽和溶(rong)液(ye)開始結(jie)晶(jing)而緩慢釋放出(chu)熱(re)量。
暖手器可以帶上飛機嗎
暖手器里含有的(de)過飽和溶液屬(shu)于(yu)液體,并且含量大(da)于(yu)100ml,因此規定是(shi)不能帶(dai)上飛機(ji)的(de),只能辦理托運。
暖手器里面是什么液體
一種(zhong)(zhong)就是(shi)(shi)過(guo)飽(bao)和(he)溶(rong)(rong)(rong)(rong)(rong)液(ye)醋酸鈉(sodium acetate, CH3COONa),是(shi)(shi)一種(zhong)(zhong)過(guo)飽(bao)和(he)溶(rong)(rong)(rong)(rong)(rong)液(ye)。過(guo)飽(bao)和(he)溶(rong)(rong)(rong)(rong)(rong)液(ye)就是(shi)(shi)一定溫度、壓(ya)(ya)力下(xia),當溶(rong)(rong)(rong)(rong)(rong)液(ye)中溶(rong)(rong)(rong)(rong)(rong)質的(de)(de)濃度已(yi)超過(guo)該溫度、壓(ya)(ya)力下(xia)溶(rong)(rong)(rong)(rong)(rong)質的(de)(de)溶(rong)(rong)(rong)(rong)(rong)解(jie)度,而(er)溶(rong)(rong)(rong)(rong)(rong)質仍不析(xi)出的(de)(de)現(xian)象叫(jiao)過(guo)飽(bao)和(he)現(xian)象。 暖(nuan)手寶里面(mian)的(de)(de)液(ye)體就是(shi)(shi)這(zhe)種(zhong)(zhong)液(ye)體了(le),有些人說是(shi)(shi)水,其實不是(shi)(shi)水,是(shi)(shi)溶(rong)(rong)(rong)(rong)(rong)液(ye)。正(zheng)常使(shi)用無毒。另外一種(zhong)(zhong)就是(shi)(shi)正(zheng)常的(de)(de)水,插電加溫至65度自動(dong)斷電。
