What are the reasons for the aging of Calcium Oxide CaO
1. The influence of temperature
The effect of temperature on Calcium Oxide CaO occurs only at high temperature, because increasing the temperature can cause thermal cracking or thermal cross-linking of Calcium Oxide CaO. And the basic effect of heat is activation. This will increase the oxygen diffusion rate and activate the oxidation reaction, thereby accelerating the oxidation reaction rate of Calcium Oxide CaO, which will cause the aging phenomenon of Calcium Oxide CaO, which is also called thermo-oxidative aging.
2. Water impact
There are many phenomena that can occur between water and Calcium Oxide CaO, a solid powdery substance. One is that it may be eroded by water to cause moisture deterioration and aging; the other is to chemically react with water to cause limewater. The phenomenon of hardening, discoloration or loss of effect occurs, so the influence of water on Calcium Oxide CaO is great.
