The scope of application of columnar activated carbon is expanding, and there are more and more studies on adsorption. As a hot product of hydrate, people have paid great attention to it. Through research, it is found that there are many factors affecting the adsorption performance of columnar activated carbon.coconut activated carbon In order to make it better used in our production and life, it is inevitable to change the pore structure and surface groups of carbon. Today, I would like to introduce to you the methods of physical modification.

The material is modified by physical methods, the volatile components are removed by carbonization, and then the carbide is activated with a suitable oxidizing gas, and the formed pore structure is formed by opening, expanding, and creating new holes. Generally speaking, there are three ways to modify columnar activated carbon by physical methods:

The main results are as follows:

(1) Heat treatment method: By changing the initial pore size, pore volume and surface chemical structure at high temperature, this method is easy to operate.

(2) Microwave method: Modification is achieved by changing the pore size, pore volume and surface functional groups by microwave, which has the advantages of fast speed, high efficiency, energy saving, strong selectivity, less pollution, and simple control.
(3) Low-temperature plasma method: By breaking the chemical bond on the surface of the material at low temperature, a new chemical bond is formed to modify the surface of the material. This method has been widely used.

The above is a physical modification method of columnar activated carbon. The adsorption performance of activated carbon is related to the pore structure and surface properties. carbon pellets manufacturer With the development of science and technology, some products produced by simple carbonization activation can no longer meet the needs of users. Especially the current development and application of activated carbon in some high, fine and sharp fields, the requirements for it are getting higher and higher, so The modification of columnar carbon is imperative.
