Structure Overview of Thermal Aging Test Chamber
It is a series of products after the modification of the original series of products. After the modification of this product, it is energy-saving, beautiful and practical, with two volumes of 100 liters and 140 liters. Non-specifications can be specially processed according to user requirements. The outer casing of all specifications of the aging test box is welded with high-quality steel plates and the surface is baked. The inner steel plate is sprayed with temperature-resistant silver powder paint or stainless steel. 50% of the shelves. A support turntable is installed in the middle, and the insulation layer is insulated with ultra-fine glass wool. The box door is equipped with double-glazed observation windows, and the joint between the studio and the box door is equipped with a heat-resistant asbestos rope to ensure the seal between the studio and the box door. The operating parts such as the power switch and temperature controller of the aging test box are concentrated in the control place on the left side of the front of the box, and operate according to the indicator.
The heating and constant temperature system in the box is equipped with a fan, an electric heater, a suitable air duct structure and a temperature controller. When the power is turned on, the fan runs at the same time. The heat generated by the electric heating directly placed in the back of the box passes through the air duct. Circulating air is formed, and the dried articles are drawn into the fan through the working room, so that the temperature is evenly circulated.
The temperature controller is an intelligent digital display, with high temperature control accuracy, a set temperature with a protective device and a timing function.
1. Put the dried items into the aging test box, and close the door and then turn on the power.
2. Turn the power switch to 'On'. At this time, the power indicator lights up and the digital temperature controller has a digital display.
3. See Appendix 1 for the setting of the temperature controller. The temperature controller shows that there is temperature in the box. Generally, the temperature control enters a constant temperature state after heating for 90 minutes. (Note: Refer to the 'Operation Method' below for intelligent temperature controller)
4. When the required working temperature is relatively low, the secondary setting method can be used. If the working temperature is 80 ° C, the first setting can be 70 ° C. When the temperature overshoot falls, set the second time to 80. ℃, which can reduce or even eliminate the temperature overshoot, so that the temperature in the box enters the constant temperature state as soon as possible.
5. Choose different drying temperature and time according to different items and different humidity levels.
6. After drying, turn the power switch to "OFF", but you cannot open the box door immediately to take out the items. Be careful of burns, you can open the box door to reduce the temperature inside the box before taking out the items.
Fourth, matters needing attention
1. The box enclosure must be effectively grounded to ensure safe use.
2. Turn off the power after use.
3. There is no explosion-proof device in the aging test box. Do not put flammable and explosive items.
4. The aging test box should be placed in a room with good ventilation, and no flammable and explosive items should be placed around it.
5. Do not overcrowd the items in the box. You must leave space to facilitate the circulation of hot air.
6, inside and outside the box should always be kept clean.
7. When the operating temperature is between 150 ℃ ~ 300 ℃, the box door should be opened to reduce the temperature inside the box after shutdown.

GB / T7762-2003 Vulcanized rubber or thermoplastic rubber resistance to ozone cracking static tensile test method
GB / T2951.21-2008 General test method for cable insulation and sheath materials,
GB / T 11206-2009 Surface cracking method for rubber aging test;
And other relevant test methods.
National standard profile: Vulcanized rubber or thermoplastic rubber resistance to ozone cracking static tensile test GB / T 7762-2003
This standard specifies test methods for resistance to ozone cracking when vulcanized rubber or thermoplastic rubber is exposed to air with a certain concentration of ozone under static tensile strain conditions and in an environment at a specified temperature without direct effects of light.
The ozone resistance of different rubber materials varies significantly with ozone concentration and temperature. The ozone strain test of tensile strain samples and the degree of damage caused by ozone during the use of products are very different due to the difference in size, type and strain.
Notes on ozone cracking properties can be found in Appendix A
