Main points of operation of ozone aging test box

The ozone aging test box can be used for rubber products such as vulcanized rubber, thermoplastic rubber, cable insulation jackets, etc., under static tensile deformation, exposed to closed and non-illuminated air containing constant ozone concentration and a constant temperature test box, as scheduled Time to test the sample, the degree of cracks or other performance changes from the surface of the sample to evaluate the resistance of the rubber to ozone aging.

During the usual test operation, we should pay attention to the following points:

1. The power supply should be equipped with an overload fuse device in the power supply line, which is dedicated to this equipment to ensure that the equipment has a good grounding device, which not only ensures the safety of the test personnel, but also ensures the service life of the equipment.

2. After numbering the test samples one by one, place the test samples on the test sample turntable, without contacting or colliding with each other, to ensure that ozone is tested on each sample at a uniform concentration during the test.

3. Close the door after completing the above points. Turn off all switches of the control system, plug in the power plug, turn the power switch turntable to turn automatically, and at the same time the power indicator light of the control system lights up, if the temperature needs to be increased, the switch (that is, the high temperature switch and the low temperature switch) must be turned on, and then adjust the automatic control system .

4. The ozone aging test box should be placed in a well-ventilated indoor horizontal position, and flammable and explosive materials should not be placed around it.

5. An iron-clad knife switch should be installed in the power supply line for this box. Please check the electrical performance of the box before the shell is grounded, and pay attention to whether there is a circuit break or leakage. This instrument is not explosion-proof The device shall not be put in flammable and explosive materials to dry.

6. Do not over-squeeze the items in the box, and leave space to facilitate the circulation of hot air.
