Guigang Lime Plant: Setting Time of Lime Powder in Cement Production

Guigang Lime Plant: The impact of different properties of free calcium oxide varies. Generally speaking, a higher content of free calcium oxide will shorten the setting time of cement. Pure quicklime, when calcined separately and added to cement, has high hydration properties due to the absence of impurities and oxides. Therefore, whether it is initial or final setting, the time will be shortened with the addition of free calcium oxide content.

Guigang Lime Plant: Industrial limestone undergoes high-temperature calcination and is finely structured under the influence of substances such as silicon dioxide, iron oxide, and aluminum oxide. Its hydration properties are higher than pure quicklime, and its hydration activity is disclosed. The higher the calcination temperature, the lower the hydration activity.

Guigang Lime Plant: The above is the content about calcium oxide introduced to you today, hoping to bring some help to you.

Precautions for using calcium hydroxide from Guangxi:

As is well known, calcium hydroxide belongs to the chemical category, and there are certain precautions when using it. Today, the editor will introduce it to you. Let's take a look at the following article together.

1. When working, attention should be paid to protecting respiratory organs, wearing work clothes made of dust-proof fibers, gloves, sealed dust-proof glasses, and applying ointment containing oil to prevent dust inhalation.

2. The storage temperature should not exceed room temperature. The compactness of solid and liquid phases in the base material accelerates with increasing temperature. If stored in a refrigerator at a temperature lower than room temperature, it can prolong the storage time. Before use, it should be allowed to return to normal room temperature in advance.

3. When in use, adjust and avoid prolonged exposure to air. When exposed to carbon dioxide in the air, it can generate calcium carbonate and lose its effectiveness.

4. Calcium hydroxide is stored in a cool and ventilated warehouse. Stay away from sources of fire and heat. It should be stored separately from acids and avoid mixing storage. The storage area should be equipped with suitable materials to contain leaked materials.
