Several tips for choosing ozone aging test box:
In order to solve the cracking of rubber products, we have developed an ozone aging test box. It can simulate and strengthen the ozone conditions in the atmosphere, study the rule of ozone on rubber, quickly identify and evaluate the anti-ozone aging performance of rubber and the protective effect of anti-ozone agent, and then take effective anti-aging measures to improve the rubber products Service life.
When we choose the ozone aging test box, don't just buy one and go back to use it, but buy it according to your needs. Here are some buying tips for you:
1. From the aspect of ambient temperature, choose according to your needs. Some products need to be tested for ozone resistance at minus zero degrees Celsius, some at room temperature (23 degrees Celsius), and some in high temperature environments, as long as you know the common testing temperature of your products. It should be noted that the room temperature test state is more commonly used. If the laboratory where the ozone aging test box is placed does not have an air conditioning system, it is recommended to choose a refrigeration system when purchasing an ozone box to avoid the high room temperature and inaccurate test during the summer test.
2. In terms of manufacturer qualifications, choose a manufacturer with strength and experience. It is also very important that experienced manufacturers provide not only instruments but also follow-up technical support.
3. In terms of the volume of the cabinet, the smaller the better. As long as the tested product can be accommodated, a box that is too large will only needlessly increase the cost of purchase. Because the material cost of ozone aging test chamber and the difficulty of ozone concentration control accuracy will increase accordingly.
4. From the perspective of sample fixtures, some need to do static testing, stretch the sample to a certain ratio, and place it in an ozone aging test box to see if there are cracks, etc .; some need to do dynamic testing, try The sample is clamped on the dynamic fixture of the ozone aging test box to see the aging situation under the dual action of mechanical fatigue and ozone accelerated aging; there are only the samples placed in the ozone box to aging.
5. In terms of ozone concentration, the general rubber test concentration is 50 pphm or 100 pphm. For rubber parts used in wire and cable or military products, the test concentration will be higher. When choosing an ozone aging test machine, it is necessary to choose the adjustable range of the concentration of the test box, and selecting the appropriate range can also improve the test accuracy.

Basalt is a volcanic stone that has been used in architecture for centuries. Although basalts boast the durability of a granite, they tend to have the consistent coloration, markings and subtlety of a limestone. Since the material is neutral in color and doesn`t etch when exposed to acidic foods, basalt is a popular kitchen countertop material.
