With the growing population, human production activities increased, resulting in the increase in garbage.
There are two ways to dispose of rubbish, one is to use the deep burial of land and the other is to burn.
Garbage incineration process, difficult enough to appear a large number of fly ash, in order to deal with these fly ash, there is a process, called fly ash curing.
So, what is fly ash curing? What kinds of additives are there in the process? One, what is fly ash curing? Fly ash curing refers to the use of a variety of curing agents, fly ash wrapped up, so that it can be centralized treatment, but also to facilitate transport without being affected by external factors such as wind and rain spread.
In short, it is to use the chemical properties of curing agent, these fly ash suction adsorption and settled in the crystal lattice.
Second, fly ash curing process of the type of additives? 1. In the process of fly ash curing, the main role is chelation, that is, chelating agent at work.
The chelating agent is divided into metal chelating agent and Non-metallic chelating agent.
But whether it is metal or non-metallic, they play the same principle.
Chelating agents and fly ash in the combination of harmful substances to form a stable chelate, this chelate is more stable than the general structure of the complex, not easy to decompose.
2. Then there is another kind of fly ash curing additive, cement.
Cement, together with water, can produce chemical reactions that produce many colloids.
And over time, the surface of the colloid also grows cilia.
In the process of curing fly ash, cement has a powerful suction adsorption function, which can tightly adhere to heavy metal deposits.
This also shows that fly ash can be cured by cement.
3. Lime.
This material is also the fly ash curing process can also play an important adsorption, fixed role.
If lime is added in the curing process of fly ash, the curing ability can be increased, so that the effect of package is better.
and lime can be combined with the acid in fly ash, forming a neutralization reaction, so that the concentration of acid in fly ash drops.
In the process of curing fly ash, in addition to adding the above mentioned curing agent, the best can also be activated carbon.
We all know that activated carbon has a strong adsorption, and its porous structure allows small molecules outside the world to be sucked adsorption.
According to Professional said, add the right amount of activated carbon, can also reduce the potential brick machine for sale the natural environment and harmful substances.
