In the process of producing cables, manufacturers are trying to avoid the aging of cables and increase the service life of cables. The use of rubber wires and cables is becoming more and more extensive. The specifications and models are becoming more and more complete. Rubber cables are anti-aging cables and rubber cables. With acid and alkali resistance, oil resistance, moisture, mold and other characteristics. What are the key factors that cause cable aging?
What are the key factors that cause cable aging? Several aspects affect cable aging: 1 Oxidation, 2 Ozone 3 Thermal Oxygen 4 Light Wave 5 Mechanical Stress 6 Moisture Oxidation Details how the cable starts to age under several influences: A) Oxygen, Oxygen Free radical chain-locking reaction occurs with the rubber molecules in the rubber, and the molecular chain breaks or excessively crosslinks, causing changes in rubber properties. Oxidation is one of the important causes of rubber aging. B) The chemically-active oxygen of ozone and ozone is much higher and more destructive. It also breaks the molecular chain, but the effect of ozone on the rubber varies with the deformation of the rubber. When used as rubber for deformation (mainly unsaturated rubber), cracks appear straight in the direction of stress action, so-called "ozone cracking," and when acting on deformed rubber, only an oxide film forms on the surface without cracking. C) Heat: Increasing the temperature can cause thermal cracking or thermal crosslinking of the rubber. However, the basic role of heat is still activating. Increasing the oxygen diffusion rate and activating the oxidation reaction, thereby accelerating the rubber oxidation reaction rate, is a common aging phenomenon - thermal oxygen aging. D) Light: The shorter the light wave, the greater the energy. Destructive effects on rubber are higher energy UV light. In addition to ultraviolet light can directly cause the breakage and cross-linking of the rubber molecular chain, the rubber generates free radicals due to the absorption of light energy, and initiates and accelerates the oxidation chain reaction process. External light plays a role of heating. The other feature of light (other than heat effect) is that it mainly grows on the surface of the rubber. For specimens with high gel content, reticular cracks appear on both sides, the so-called "outer spallation." E) Mechanical stress: Under the repeated action of mechanical stress, it will break the molecular chain of rubber to generate free helium, initiate the oxidation chain reaction, and form a force chemical process. Mechanical fracture molecular chain and mechanical activation oxidation process. How can one prevail, depending on the conditions in which it is located. In addition, ozone cracking is easily caused under stress. F) Moisture: There are two aspects of the effect of moisture: When rubber is exposed to rain or immersed in water, it is easy to damage. This is because the water-soluble substances in the rubber and the components in the water are removed by water. Caused by hydrolysis or absorption. Especially in the alternating effect of water immersion and atmospheric exposure, it will accelerate the destruction of rubber. However, under certain conditions, water does not damage the rubber, and it may even delay aging.
