Production Method of Meltblown Chrome Oxide Granules Cr2O3 Pulp:

Chemical method

The chemical method is a common method for producing melt-blown grade chromium oxide. The method uses chromium salt solution as raw material to produce melt-blown grade chromium oxide by chemical reaction. The specific steps are as follows:

The chrome salt solution (such as chromium nitrate, chromium chloride, etc.) is added to the reactor and stirred evenly.

Add an appropriate amount of alkali (such as sodium hydroxide, potassium hydroxide, etc.) to the reactor and adjust the pH value of the solution to a predetermined range.

An appropriate amount of oxidizing agent (such as hydrogen peroxide, sodium nitrate, etc.) is added to the reactor to trigger the oxidation reaction.

After the reaction is completed, the resulting melt-blown grade chromium oxide powder is filtered, washed, and dried to obtain the required melt-blown grade chromium oxide product.

The chemical method has the advantages of a mature process, simple operation, and low cost, so it is widely used in industry. However, the chemical method also has some disadvantages, such as difficulty in controlling the reaction conditions and low product purity.

Second, physical law

The physical process is another common method for producing melt-blown grade chromium oxide. The process is based on chromium metal as raw material, through a high-temperature oxidation reaction to produce melt-blown grade chromium oxide. The specific steps are as follows:

Grind metal chromium into powder and add an appropriate amount of accelerant (such as magnesium powder, aluminum powder, etc.).

The mixture is loaded into a crucible and sent to a high-temperature furnace for oxidation treatment.

At high temperatures, chromium metal oxidizes with oxygen to produce melt-blown grade chromium oxide powder.

After the reaction is completed, the resulting melt-blown grade chromium oxide powder is removed, cooled, and dried to obtain the required melt-blown grade chromium oxide product.

The physical method has the advantages of high product purity and controllable particle size, but it also has some disadvantages, such as high production cost and high energy consumption.

For the needs of different application fields, melt-blown grade chromium oxide products with specific properties and uses can also be prepared by adjusting production process parameters and adding other elements. For example, adding zinc, cobalt, and other elements can be prepared with excellent magnetic properties of magnetic materials. The particle size and morphology of chromium oxide powder can be controlled by adjusting oxidation time and temperature.
