Winter is coming. In such a cold weather, especially for customers in the north, what problems should customers using double glass reaction kettle pay attention to? Yaote instrument will analyze and answer for you!
Northern customers should first pay attention to the fact that if the heat conducting medium used in the interlayer of the glass reactor and the condensing tube you use is water, you must pay attention to the low-temperature icing. In a static state, the water will expand after freezing, which will explode the glass reactor body or the condensing tube. Therefore, the water in the interlayer and condensing pipe should be drained after the experiment to avoid freezing at low temperature.
Another problem is that the temperature rise of the double-layer glass reactor is slow in winter, and the higher the capacity of the reactor, the slower the temperature rise. To solve this problem, Yaote made the following solutions:
1、 Select special insulation cotton to wrap the double-layer glass reactor, which has the effect of insulation, can effectively prevent excessive temperature loss, and provide heating speed. If you choose Yaote double glass reactor, we will give you insulation cotton to solve your winter troubles.
2、 Appropriately increase the set temperature of the high-temperature oil bath (high-temperature circulator) to make the double-layer glass reactor accept higher temperature and shorten the heating time. When the reactivity of the double glass is close to the operating temperature, the temperature of the high-temperature oil bath (high-temperature circulator) is reduced to the actual operating temperature.
For example, the actual use temperature is 100 ℃, and the temperature of the high-temperature oil bath (high-temperature circulator) can be set to 120 ℃. When the temperature of the double-layer glass reactor rises to about 90 ℃, the temperature of the high-temperature oil bath (high-temperature circulator) can be set to the required: 100 ℃. It can effectively improve the heating rate and shorten the waiting time.
3、 The solution in the double-layer glass reactor should not be filled at one time, which will affect the heating rate. You can choose the batch feeding method. The initial feeding is about half of the capacity. After the temperature rises to close to the set temperature, add materials to the reactor. According to the above method, adding liquid in batches can also effectively provide the heating rate.
The above three methods to improve the heating rate and work efficiency can be selected by users according to their actual situation. Yaote instrument is looking forward to cooperating with you. The hotline is 4000-111-217
