[0039] Embodiment 1: The heating bath 1 is an open-top structure, and the interior of the electric heating layer 2 includes an electric heating wire. This device is specifically used for heating and boiling polypropylene injection molded samples. Specifically, the polypropylene injection molded samples are boiled in the heating bath 1, and the boiling temperature is constant at 98-99 degrees Celsius. The boiling time is more than 100 hours. The boiling water is heated by electric heating. The principle of keeping the boiling temperature constant is that the temperature sensor monitors the water temperature in real time and feeds the data back to the thermostat. When the water temperature is lower than the set value, the thermostat will start the heating element, such as the electric heating wire, to generate heat and heat the water. On the contrary, when the water temperature exceeds the set value, the thermostat will turn off the heating element to prevent the water temperature from continuing to rise.

[0043] The boiling temperature is constant at 98-99 degrees Celsius, the boiling time is more than 100 hours, and the boiling water is heated by electric heating. The principle of keeping the boiling temperature constant is that the temperature sensor monitors the water temperature in real time and feeds the data back to the thermostat. When the water temperature is lower than the set value, the thermostat will start the heating element, such as the heating wire, to generate heat and heat the water. On the contrary, when the water temperature exceeds the set value, the thermostat will turn off the heating element to prevent the water temperature from continuing to rise. Through this cycle control, the water temperature can be kept stable and fluctuate within the range of 98 to 99 degrees, so that the polypropylene sample can be boiled at a constant temperature;

The samples are not directly put into the device, but are loaded into the sample cage 8. Under the control of the cylinder 7, the sample cage 8 can be lowered into the device with the samples to heat the samples. The side of the sample cage 8 is provided with a cage door 10 that can be opened and closed automatically. When taking the samples, there is no need to manually pick them up. Since the samples are located in the sample cage 8, it is only necessary to retract the cylinder 7, raise the sample cage 8, retract the output end of the electric cylinder 14, and open the cage door 10. At this time, the samples can be easily taken out. Therefore, the device is convenient for taking and putting polypropylene samples.

[0047] 2. The constant temperature heating equipment for the polypropylene sample that is easy to take and place adopts the form of electric heating and boiling water. The principle of keeping the boiling temperature constant is that the temperature sensor monitors the water temperature in real time and feeds the data back to the thermostat.
