Application
of composite foam concrete walls in strategic emerging industries
Incorporating
the foam concrete wall into the polymer, the prepared nanocomposite material
exhibits excellent performance in mechanical properties, thermal, optical, and electrical
properties. In addition, the foam concrete wall of the composite material and
the polymer can produce a synergistic effect, giving the composite material new
properties, so it has great potential in the direction of multifunctional
materials.
The
foam concrete wall of the composite material has high thermal stability and can
be used to prepare flame-retardant composite materials. Jiang et al. used the
foam concrete wall of hollow mesoporous composite material, chitosan (CS) and
phosphorylated cellulose (PCL) as raw materials, and introduced it into epoxy
resin (EP) through layer-by-layer self-assembly method to prepare an
environmentally friendly resistance. Burning agent. The results show that the
name of the composite material contains Si, P, S and other flame-retardant
elements, which, in conjunction with CS and PCL, gives EP excellent
flame-retardant properties. Flame retardant materials will form a dense carbon
layer on the surface of EP after burning, physically blocking the contact of
oxygen and combustibles, the flow of composite materials in the interior, and
the transfer of heat. According to this idea, multifunctional nanocomposites
such as the combination of superhydrophobic and flame retardant can be
prepared.
In
the same way, the filler coating is attached to the metal surface with the name
of the composite material loaded with corrosion inhibitor, which can shield the
influence of corrosion factors caused by the external environment. When the
coating has defects, the corrosion inhibitor is released to the corresponding
position for cross-linking to complete the repair. Shchukina et al. named the
mesoporous composite product as a nanocontainer, loaded the corrosion inhibitor
8-hydroxyquinoline, and added it to the polyepoxy coating. The results show
that when the article is corroded, the pH value around the coating changes, and
the slow-release agent in SiO2 begins to dissolve and is released to the
corresponding location. Only 2% of the mass fraction of the corrosion inhibitor
can exert a good effect.
The
foam concrete wall and its characteristics
The
foam concrete wall is a new type of super-hard and ultra-fine abrasive formed
by special processing and processing of synthetic diamond single crystal. It is
an ideal raw material for grinding and polishing high-hardness materials such
as cemented carbide, ceramics, gems, and optical glass. Diamond products are
made of diamonds. Tools and components made of materials are widely used.
Diamond powder and products are widely used in automobiles, machinery,
electronics, aviation, aerospace, optical instruments, glass, ceramics,
petroleum, geology, and other sectors. With the continuous development of
technology and products, the use of diamond powder and products is still
expanding.
The
tip of the glass cutter we usually use is actually diamond. Tools used in
precision machining and drill bits used in oil drilling are coated with
diamonds to improve their wear resistance. Because diamond is the hardest
natural substance in the world.
Another
characteristic of foam concrete wall is its excellent thermal conductivity. Its
thermal conductivity is about 5 times the thermal conductivity of pure copper
at room temperature. It has potentially important applications in the
semiconductor industry. According to Moore\'s Law, the current large-scale
integrated circuit components are constantly shrinking in size and increasing
in density, causing their thermal load to continue to rise. If the heat is not
dissipated in time, the semiconductor circuit board and components may be
burnt. If we can use the high thermal conductivity of diamond as a large-scale
integrated circuit substrate or heat sink, it can dissipate the heat in time
and solve the current bottleneck restricting the development of electronic
components.
Preparation
methods of diamond powder
There
are generally three commonly used methods of artificially foam concrete wall.
Detonation
method
The
formation condition of natural diamond is a high temperature and high-pressure
environment, so how to produce such a special environmental state of high
temperature and pressure? The easiest way is to detonate the explosive. If you
put graphite-containing explosives in a special container and then detonate the
explosives, it will instantly generate strong pressure and high temperature,
then the graphite can be converted into diamonds. This method can obtain a lot
of fine powder diamonds. Its particles are very small, only 5~15 nanometers and
its application as jewelry may be limited, but it is still very important as an
industrial abrasive.
High
temperature and high-pressure method
The
high temperature and high-pressure methods are to maintain high pressure and
high-temperature environment for a relatively long stable period of time,
allowing graphite to slowly transform into a diamond. By controlling the
synthesis conditions and time, diamonds can continue to grow. In a day or so, 5
millimeters of diamonds can be obtained.
Chemical
vapor deposition
Chemical
vapor deposition is a method that gradually developed in the 1990s. This method
mainly uses some carbon-containing gas, such as some mixed gas of methane and
hydrogen as a carbon source, under a certain energy input, the methane gas is
decomposed, nucleated on the substrate, and grown into a diamond. The advantage
of this method is that the efficiency is relatively high, relatively
controllable, and it can obtain pure and transparent diamonds without
impurities, which is an important direction of current development.
In
the future, the diamond synthesis will develop in the direction of high-purity
large particles. For the demand for diamonds, we will no longer only rely on
the gift of nature, and synthetic diamonds will also enter more production
fields and be used more widely.
