產品描述

All charcoal structures are based on graphite lattices and in some respects differ from graphite. The
structure of graphite is a hexagonal network structure of large
aromatic planar molecules, which is composed of layers stacked in
three-dimensional order. Activated carbon, charcoal, coke and carbon black, forming a family called "amorphous carbon" carbonaceous material. The
structure of these materials is more or less similar to the graphite
structure, but compared with the graphite lattice, there are four
aspects of the size of the ply, the degree of perfection of the
hexagonal array of carbon atoms in the layer, the degree of
planarization and the layer spacing Different degrees of difference.

On
the nature of activated carbon adsorption capacity, early research
understanding is: activated carbon, such as decolorization, adsorption
capacity is chemical or heat treatment after the "activation" has the
nature, it is called "activated carbon" (activated carbon), it turns out
that this is A misunderstanding Modern practice and theoretical studies have shown that: Activated
carbon has a strong adsorption capacity, mainly because it has a special
microcrystalline structure, and highly developed microporous and huge
surface area.


 


Activated
carbon adsorption not only shows the ability of physical adsorption,
but also often shows the characteristics of chemical adsorption, which
has a close relationship with the chemical composition of activated
carbon surface. In
practice, it is often found that activated carbons with similar pore
size distribution and the same specific surface area show distinctly
different adsorption properties due to different manufacturing methods.
The main reason for this is that activated carbons prepared by different
methods have different surface chemical compositions: water vapor
prepared Activated
carbon, oxygen mainly in the form of hydroxyl and carboxyl groups; zinc
chloride production of activated carbon, carbonyl oxygen and ether
oxygen accounted for a large proportion. Activated carbon surface polarity, acid-base and wettability directly
affect the adsorption of the selectivity and catalytic properties.

Activated carbon amorphous carbon structure is composed of several
layers parallel to the carbon network plane composed of microcrystals
and other non-parallel layer composed of a single network plane and no
planning of carbon three components. 
Activated carbon adsorption occurs mainly because of surface energy. Adsorption (adsorption) is the material in the two-phase interface concentration phenomenon. Matter is made of molecules, and molecules are made of atoms or ions. Since
the atoms or groups of atoms that make up the molecule bear the
opposite charges, the molecules are electrically neutral to the outside. Since
the atomic layer (surface, interface) constituting the outermost layer
of a material is unbalanced due to the absence of atoms of the opposite
outer layer, it has the effect of grasping other molecules in the
outside world to balance their own electrical properties Trend
--- Surface energy or surface potential; Due to the free flow of gases
and liquids (collectively referred to as fluids), they are easily
trapped by large surface solids. When
a fluid is in contact with a porous solid, one or more components of
the fluid accumulate (solidify) at the solid surface, a phenomenon known
as "adsorption." The larger the surface, the stronger the electrical
properties of the material. The tendency and ability to grasp other components to reduce their own surface potential energy is stronger. Because activated carbon has a large specific surface area, so that the most significant feature is the adsorption.

In
the water quality pretreatment system, the activated carbon filter can
adsorb residual chlorine that can not be removed in the pre-filtration
to prevent the reverse-osmosis membrane of the subsequent stage from
being oxidatively degraded. At the same time, it also adsorbs pollutants
such as small molecule organic substances leaking from the previous
stage. Odor in water, colloids and pigments, heavy metal ions, COD and other more obvious adsorption and removal. Can further reduce the SDI value of RO water, to ensure SDI <5, TOC <2.Oppm.
