What is activated carbon? Is it the same as ordinary carbon? What does activated carbon mean by its activity?
The most basic understanding of these activated carbons is that it is necessary to make an understanding when we reuse them.
What does the activity of activated carbon mean?
What is activated carbon? Activated carbon is a kind of adsorptive material with abundant scale, which is prepared by physical or chemical methods, using oxidizing gases or chemicals to react and pore at high temperature.
Is activated carbon the same as ordinary carbon? It must be different. Let's take a look at the process of activated carbon.
Activated carbon is refined from high quality coal, sawdust, fruit shell, coconut shell and other materials with advanced technology and equipment. Activated carbon production process is roughly divided into: carbonization cooling activation washing and a series of refined processes.
We all know that ordinary carbon is made of wood and other materials heated to a certain temperature under hypoxic conditions, through drying, pyrolysis, melting, bonding, curing, shrinkage and other stages.
Actually, the biggest difference between ordinary carbon and activated carbon lies in the word "activity" in front of it.
Activated carbon will become the highly developed microporous microcrystalline structure after activation process, which can produce an adsorption force on the filtered substance molecules through Van der Waals force, and adsorb these substances into its own interior. This is a function that ordinary carbon does not have. This is the activity of activated carbon.
