For everyone to answer the air heat aging test chamber in daily use need to pay attention to the matters

The principle of action of the air heat aging test chamber: the performance of the specimen is determined after aging in the air at high temperature and atmospheric pressure, and the performance of the unaging specimen is compared
.

The physical properties related to the right of use are used to determine the degree of aging, and in the absence of a precise identification of these properties, it is recommended to determine tensile strength, constant tensile stress, tensile elongation and hardness
.

This product is suitable for heat resistance test of non-metallic materials, ventilation aging test test of electronic parts and plasticized products
.

To assess and judge its adaptability for storage and use under high temperature environmental conditions, the specimen is measured and compared
with the performance of the unaged sample after simulating air aging at high temperature and atmospheric pressure.

Air heat aging test chamber operating skills: 1, in the operation, unless absolutely necessary, please do not open the box door, otherwise it may lead to the following adverse consequences
.

2.
Circuit breaker and over-temperature protector are to provide local test products and operator safety protection, so please check
regularly.

3.
If the heat sample is placed in the box, please use the external power supply for the power control of the sample, and do not directly use the local power supply
.

4.
In any cross-section perpendicular to the dominant wind direction, the sum of the cross-sectional areas of the test load should not be greater than one-third
of the working sections at that place.

5, the test chamber in the installation of the box shell must be grounded, if the test chamber is not grounded, once the leakage of electricity will have the risk of
electric shock.

Air heat aging test chamber in daily use need to pay attention to the matters: 1, hot air aging test chamber placement position before and after the left and right of 80 cm can not put things; 2.
Long-term shutdown is not applicable, and the aging test chamber should be energized regularly every half a month, and the power-on time is not less than one hour; 3.
Clean the condenser every three months, decontaminate and remove dust to ensure its good ventilation performance; 4.
Clean the evaporator every three months; 5, waterway, humidifier cleaning: if the waterway is not smooth, humidifier scaling, easy to cause the humidifier to dry burning, may damage the humidifier, so it must be regularly cleaned on the waterway, humidifier; 6.
The ventilation type aging test chamber insists that after each experiment is completed, the temperature is set near the ambient temperature, working for about thirty minutes, and then cut off the power supply and wipe the wall
of the studio.
