g of molecular chains caused by ultraviolet rays, calcium oxide generates free radicals due to the absorption of light energy, which initiates and accelerates the oxidation chain reaction process. The outside light plays a heating role.

5. Microbial influence

In different environments, there will be many different microorganisms in the air. Different microorganisms and different substances will react differently. If calcium oxide is exposed to the air for a long time, it may interact with each other. The microorganisms in the air react with each other, resulting in aging or deterioration.

6, the influence of chemical medium

Calcium oxide is an alkaline substance and will react with acidic substances, so it is isolated from acidic substances, and it will also undergo deterioration or aging when reacting with other chemical substances. Therefore, you must pay attention to the calcium oxide in the process of storage, take good care of it, keep it away from water sources and some chemicals, and prevent chemical media from affecting calcium oxide and causing aging.

7, stress effect

Calcium oxide will break the molecular chain of calcium oxide under repeated mechanical stress to generate free radicals, trigger the oxidation chain reaction, form mechanochemical process, mechanically break the molecular chain and mechanically activate the oxidation process, resulting in deterioration or aging.ax
