暖手器的用法
首(shou)先充電(dian)(dian),通電(dian)(dian)時,人不(bu)得離開,等待充電(dian)(dian)結束(shu),指(zhi)示(shi)燈自動熄滅,拔掉插頭(tou)和連接器后(hou)就可以將暖(nuan)手器裝入保溫(wen)袋內用(yong)于手部取暖(nuan)了。注(zhu)意(yi)通電(dian)(dian)時不(bu)要(yao)將電(dian)(dian)熱(re)暖(nuan)手器抱在懷中。
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(zhi)量、大小等(deng)因素有所差(cha)異,建議購買保溫時(shi)間長的優質(zhi)暖(nuan)手(shou)器。
暖手器發熱原理
暖(nuan)手(shou)器(qi)發熱原理(li)簡單(dan)來說是(shi)插(cha)上(shang)電(dian)源后,通(tong)過(guo)電(dian)熱元件(電(dian)熱絲(si)或PTC陶瓷元件)來加熱暖(nuan)手(shou)器(qi)里的過(guo)飽和溶(rong)液,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)以后,電(dian)熱暖(nuan)手(shou)器(qi)的過(guo)飽和溶(rong)液開始結(jie)晶(jing)而(er)緩慢(man)釋放(fang)出(chu)熱量。
暖手器可以帶上飛機嗎
暖(nuan)手器里含有的過飽和溶液屬于液體(ti),并(bing)且含量大(da)于100ml,因(yin)此(ci)規定是不(bu)能(neng)帶上飛機的,只能(neng)辦理托運。
暖手器里面是什么液體
一(yi)種就(jiu)是(shi)(shi)過飽(bao)和(he)溶(rong)(rong)(rong)(rong)液(ye)醋(cu)酸鈉(sodium acetate, CH3COONa),是(shi)(shi)一(yi)種過飽(bao)和(he)溶(rong)(rong)(rong)(rong)液(ye)。過飽(bao)和(he)溶(rong)(rong)(rong)(rong)液(ye)就(jiu)是(shi)(shi)一(yi)定溫(wen)(wen)度(du)(du)、壓力下(xia),當(dang)溶(rong)(rong)(rong)(rong)液(ye)中溶(rong)(rong)(rong)(rong)質(zhi)(zhi)的濃度(du)(du)已超過該溫(wen)(wen)度(du)(du)、壓力下(xia)溶(rong)(rong)(rong)(rong)質(zhi)(zhi)的溶(rong)(rong)(rong)(rong)解度(du)(du),而(er)溶(rong)(rong)(rong)(rong)質(zhi)(zhi)仍(reng)不析出的現(xian)象叫(jiao)過飽(bao)和(he)現(xian)象。 暖(nuan)手寶里(li)面的液(ye)體就(jiu)是(shi)(shi)這種液(ye)體了,有些人說是(shi)(shi)水,其實不是(shi)(shi)水,是(shi)(shi)溶(rong)(rong)(rong)(rong)液(ye)。正常使用無毒。另外一(yi)種就(jiu)是(shi)(shi)正常的水,插電加溫(wen)(wen)至(zhi)65度(du)(du)自動斷電。
