应用

The content of ozone in the atmosphere is very small but it is the main factor of rubber cracking. This product simulates and strengthens the ozone conditions in the atmosphere, studies the law of the effect of ozone on rubber, and quickly identifies and evaluates the ozone resistance and aging resistance of rubber. The method of anti-ozonant protection efficiency. Reference standard: GB/T7762-2003 vulcanized rubber or thermoplastic rubber anti-ozone cracking static tensile test method, GB/T2951.21-2008 cable insulation and sheath material general test method, GB/T 11206-2009 Rubber aging test surface cracking method, and other test methods specified in related standards.

1.2。原理和方法

根据测试方法和标准，可以将测试方法分为“静态”和“动态”。静态意味着将样品拉伸并放置在测试框中进行测试，而动态表示样品放在测试框中。在固定装置上，在拉伸时进行测试，拉伸的波动约为测试样品本身的5％-45％

3.4. Requirements of the sample rack

a）（动态实验；可选）样品的两端，夹在所需的伸长率下。当与臭氧空气接触时，样品的长度应基本平行于气流方向

b）固定装置应由不容易分解臭氧的材料（例如铝）制成。

c）使样品旋转速度在（20^-25）mm/s之间，在垂直干燥空气平面中，每个样品沿着相同的路径连续移动

d) The time for one rotation of the same sample is (8^-12) min. The scanning area of the sample is at least 40% of the effective area of the test box.

e)应该满足从样品制备ents of GB/T 9865.1. The sample is best cut from the newly molded test piece, if necessary, it can be cut from the finished product. The sample should be at least 3 samples per test condition. The width of the long standard sample is not less than 10mm, the thickness is 2.0mm±0.2mm, and the length of the sample between the two ends of the clamp before stretching is not less than 40mm.
