Description

一种共晶液
本发明涉及一种共晶液，更具体说涉及一种制造蓄冷器用的共晶液。
现有的制蓄冷器用的共晶液由水，尿素和少量氯化铵所组成，其冰点为-12℃，释放冷量小，时间短，不能满足市场的需要。
本发明的目的是提供一种新的共晶液，它能弥补现有共晶液的上述不足。
本发明的共晶液，其特征是由水、尿素、氯化铵和磷酸氢二钠所组成，它们的重量百分数分别是60-70，25-32，3-7和0.000001-0.00001。
本共晶液的冰点为-20--22℃，释放冷量大，用它制成的蓄冷器放在保温箱或其它容器里，能保持冷饮、冰糕等长时间不融化，也可用于长途运输，以满足用户的需求，本共晶液没有腐蚀性，使用方便，价格低廉。
下面通过实施例说明本发明。
在配制槽中，放入640Kg水，调温至25℃，将296Kg尿素，39Kg氯化铵和0.08g磷酸氢二钠倒入槽中，搅拌均匀即为本发明的共晶液；将此分装在塑料壳中密封，即为蓄冷器。
为了与现有的共晶液对比，将两种共晶液各取100ml放入同一冰柜中，分别插入数字测温仪。当温度降到-33℃完全冷冻后，断电，温度开始回升，7小时后，现有共晶液的温度回升到-16.4℃，而本发明的共晶液的温度只回升到-20.0℃，两种晶体都开始熔化。据此可见，本发明的共晶液冰点低，释放冷量大。
