Composition of fly ash solidification chelating agent

Fly ash solidification chelator is a chemical substance used to treat and solidify fly ash (i.e. residual ash after coal combustion) from coal-fired power plants. Its main components include the following:

Silicate: Silicate is one of the main components of fly ash solidification chelating agent. Common silicates include calcium silicate, sodium aluminum silicate, etc. They can react with oxides and metal ions in fly ash to form stable compounds and promote the solidification process.

Active minerals: Active minerals such as fly ash, cement clinker, etc. are widely used in fly ash solidification chelating agents. They have highly fine particles and good activity, which can combine with particles in fly ash to provide mechanical strength and stability.

Chelating agent: A chelating agent is a compound that can form a complex with metal ions. In fly ash, there are some harmful metal ions, such as heavy metals. The addition of chelating agents can combine these metal ions with chelating agents to form insoluble or inactive compounds, reducing their harm to the environment.

Auxiliary additives: The fly ash solidification chelating agent may also include some auxiliary additives, such as flowability regulators, thickeners, binders, etc. These additives can improve the process performance of the curing process and the performance of the product.

It should be noted that different manufacturers and products may use different ingredients and formulas. When using fly ash solidification chelating agent, appropriate products should be selected based on the specific situation, and the correct dosage and operation should be carried out according to the product instructions. In addition, solidified fly ash products should also comply with relevant standards and regulations to ensure their safety and environmental friendliness.
