Graphene Spray Dryer
Detailed description
Graphene Spray Dryer
project description:
Jiangsu Yutong Drying Engineering Co., Ltd. has been
dedicated to the research and practice of drying technology and new
materials, and provide technical support for many new drying material
manufacturer. Not long ago, a domestic manufacturer of graphene contact
with me on issues of graphene drying equipment with our company for a
number of in-depth discussion. Our sample workshop with a spray drying
equipment can be used for drying graphene simulation test. The final
conclusion is: using a spray can graphene dried to meet the technical
requirements of graphene dry goods.
Item Description:
Graphene (Graphene) is stripped out from the graphite
material, composed of carbon atoms only one atom thick two-dimensional
crystal. In 2004, the University of Manchester physicist Andrei lid Farm
and Konstantin Novoselov, successfully isolated graphene from graphite,
it confirmed that it can stand alone, and therefore they also shared
the 2010 Connaught Nobel Prize in Physics. Graphene not only the
thinnest material, is the most robust materials, fracture strength is
even higher than the best steel 200 times. At the same time it have good
flexibility, tensile amplitude can reach 20% of its own size. It is the
nature of the thinnest, highest strength material, if made hammock with
an area of 1 square meter of graphene, its own weight less than 1
milligram can withstand a one kilogram cat. Graphene is currently the
most promising applications is becoming a substitute for silicon
manufacturing ultra-miniature transistors, for the production of future
supercomputers. Replacing silicon with graphene, the operating speed of
the computer processor will be hundreds of times faster. In addition,
graphene is almost completely transparent, absorbed only 2.3 percent of
the light. On the other hand, it is very compact, even the smallest gas
atom (helium atoms) can not penetrate. These characteristics make it
very suitable as a raw material transparent electronic products, such as
a transparent touch screen, light board and solar panels.
As the discovery of the thinnest, highest intensity, the
strongest thermal conductivity properties of a new type of
nano-materials, graphene is known as "black gold" and "King of new
materials," scientists have even predicted that graphene will
"revolutionize the 21st Century . " It is likely to lead to a disruptive
new technology sweeping new global industrial revolution.
China Telecom held in Guangzhou Trade Fair 2016 Tianyi
intelligent terminal, unveiled a graphene Luoma Shi Bao charging 10
minutes can be filled 6000mAh, claims to "open up a new era of energy
storage."
Engineering principles:
Graphene drying has been involved. As a new type of lithium
battery materials, it has a very broad market prospects lithium
dryer. Currently in graphene production process, common mainly: slight
rubbing method or tear tape method (paste H0PG), SiC heating method, a
metal substrate by chemical vapor deposition, oxidation-reduction
method. Since the first three methods yield is low or the equipment is
expensive, tedious process and other reasons not suitable for mass
production of graphene. Redox method because of its advantages of higher
yield relatively more suitable for mass production. It is prepared by
oxidation of customers reducing graphene method. Wherein the redox along
with advances in technology, the traditional redox prepared graphene
using hydrazine hydrate as reducing agent is prepared, because of their
highly toxic nature, it has been gradually phased out Reduction Act
replaced. That the use of 1000 ℃ high temperature in the reduction
reaction, leading equipment microwave oven. Using this microwave
irradiation Preparation of graphene a very short cycle, low cost, simple
operation, but must request a powder state into a microwave
furnace. Water graphite oxide to be dehydrated into a powder, then
microwave heating and, ultimately, graphene dry goods. My company after
full understanding of the process, and ultimately the use of a spray
drying graphene.
