Cautions for operation of ozone aging test chamber
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 overloaded fuse device in the power supply line. This box is special 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 so that they do not contact or collide with each other to ensure that the ozone is tested on each sample with a uniform concentration during the test.
3. Close the door after completing the above points. Turn off each switch of the control system, insert the power plug, turn on the power switch, and turn the dial to turn automatically 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 blade switch should be installed in the power supply line for this box. Please check the electrical performance of this box before the shell is grounded, and pay attention to whether there is a circuit break or leakage. This instrument has no explosion-proof devices , Do not put 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.
