3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Frosting blooming
The phenomenon in which the liquid or solid compounding agent in the compound migrates from the inside to the surface.
4 Principle
4.1 Ozone aging method
Under the ozone environment, the surface of the rubber sole will accelerate the aging, so that unstable substances in the rubber with potential blooming phenomenon will accelerate the tour.
Leaving (migration) precipitates and blooming occurs.
4.2 Temperature-resistant salt water immersion method
Soak the rubber sole in salt water for a certain period of time, then place it in high and low temperature for a certain period of time, and change it by temperature change.
Stabilize the solubility of the substance and observe whether or not the blooming phenomenon and the degree of blooming are evaluated to evaluate the blooming performance.
5 Instruments and materials
5.1 Ozone aging test chamber
5.1.1 Ozone generator
According to 5.2, 5.3, and 5.4 of GB/T 7762-2014, equipped with ozone generating and adjusting and measuring ozone concentration, from ozone
The ozone-containing air from the generator is heated in a heat exchanger and then input into the test chamber.
5.1.2 Test chamber
The test chamber should be sealed, the temperature control range is 20 ° C ~ 100 ° C, the relative humidity control range is 30% ~ 95%, and can be constant
