This article will ** the reasons for the insufficient strength of columnar activated carbon. First, let's understand the basic concept of columnar activated carbon and its importance in the application.
Columnar activated carbon is an efficient and environmentally friendly purification material, which is widely used in water treatment, air purification, desulfurization and denitrification and other fields. Its unique pore structure and physicochemical properties make it have excellent adsorption performance and filtration effect. However, sometimes we will find that the strength of columnar activated carbon is not enough, resulting in problems such as crushing and pulverization during its use, which will adversely affect the purification effect and service life.
So, what is the reason why the strength of columnar activated carbon is not enough?
1.Poor quality of raw materials.
The raw materials of columnar activated carbon are mainly woody, coal and other carbon-containing substances. If the raw material quality is poor, such as low carbon content, more impurities, etc., it will directly affect the physical and chemical properties of activated carbon, including strength. Therefore, the selection of high-quality raw materials is the basis for the production of high-strength columnar activated carbon.
2.The preparation process is unreasonable.
The preparation process of columnar activated carbon mainly includes activation, rinsing, drying and other links. If the preparation process is unreasonable, such as improper control of activation temperature and time, incomplete rinsing and drying, etc., it will affect the pore structure and physical properties of activated carbon, thereby reducing its strength. Therefore, optimizing the preparation process is the key to improving the strength of columnar activated carbon.
3.Improper storage and use environment.
The storage and use environment also has a certain effect on the strength of columnar activated carbon. If the storage and use environment is humid and dusty, it will cause the activated carbon to become damp and absorb a large number of impurities, thereby reducing its strength. Therefore, the correct storage and use environment is a necessary condition to ensure the strength of columnar activated carbon.
