What do you rely on to keep warm in winter?
The northern region mainly relies on water heating, which is divided into two types: water floor heating and radiator;What about the southern region? Basically rely on shaking!
Many people only know that the winter in the south is wet and cold, but they don’t understand how cold it really is. Meteorology generally believes that for every 10% increase in humidity, the temperature felt by the human body decreases by 1°C. To put it figuratively and directly, in an environment of 0℃ in the south, it feels like -10℃ in the north.
Of course, relying on shivering for warmth is just a joke. Southerners can still rely on air conditioners or electric heaters during the winter. But to be honest, is it really dry and uncomfortable to turn on the heating and air conditioning in winter? Mom and wife, don’t you really feel worried about the electricity bill?
In northern areas, water heating is much more comfortable than heating and air conditioning in winter. However, this is very expensive for individuals and families; it also consumes a lot of energy and pollutes the country. Because, from an environmental protection point of view, water heating mostly uses coal and oil as heating raw materials. They will emit a large amount of harmful gases and dust during the combustion process, which is the main component of air pollution. This is also the case in the north during the heating season. Reasons for frequent smog.
Some readers may be thinking after seeing this: Having said so much, does it have anything to do with graphene?
Of course.
Graphene is a two-dimensional carbon nanomaterial with a hexagonal honeycomb lattice composed of carbon atoms with sp² hybrid orbitals.
Don’t understand? That's right. The editor also seems to understand this awkward professional definition, and pretends to understand it.
In fact, you don’t need to pay attention to this boring definition, you just need to know: Graphene is a material with very good thermal conductivity.
Its thermal conductivity reaches 5300W/mK, and its thermal conductivity is 13 times that of copper and 1.51 times that of carbon nanotubes. It is the best thermal conductive material at room temperature.
So does this have anything to do with ceramic tiles?
This is where the point comes.
Graphene + tiles = graphene tiles
Graphene ceramic tile is a ceramic tile with graphene embedded inside the ceramic tile, which can quickly generate heat and provide effective heating after being powered on.
As a kind of functional ceramic tile, heating ceramic tiles are favored by some ceramic companies. As far as the author knows, the brands currently producing heating tiles include Fenfang (Fragrance negative ion graphene heating tiles), Mark Martin (Mark Martin graphene tiles), Mingguan (Mingguan graphene heating floor tiles), etc.
Compared with ordinary heating tiles that use electric heating tubes (wires) for heating, what is the difference between graphene heating tiles?
On the opening day of the Tanzhou Exhibition on April 19, the author got the answer when interviewing Dr. Chen Ran, the head of the New Pearl Group’s doctoral workstation, before the launch ceremony of Grace’s graphene smart heating tiles.
Dr. Chen Ran said that the graphene used in Grace graphene smart heating tiles is a two-dimensional planar structure membrane material, while the electric heating tubes (wires) or conductive fibers used in other heating tiles are Ring-shaped ones, and of course some heating tiles use granular carbon black and carbon crystals. However, whether it is annular electric heating tubes (wires) and conductive fibers, or granular carbon black and carbon crystals, they do not have the flexural strength of two-dimensional planar graphene and can be bent at will, so their service life is far less than that of graphite. The lifespan of graphene can be as long as decades.
As for the problems that the author is worried about for southern compatriots when laying graphene heating tiles at home, such as moisture and leakage, Dr. Chen Ran also answered them one by one.
There is a 150 degree high temperature resistant vacuum membrane above and below the Grace graphene smart heating tile heating source. You can pierce it with a nail, cut a slit with scissors, or even leave it in a fish tank to soak for a few days. The fever is still there and the fish is fine. In terms of electrical safety, Grace graphene smart heating tiles have three layers of protection: first, a power overheating protection device is set at the power switch; second, graphene itself has an automatic protection function, no matter how it is powered on, it will not exceed 50 degrees; third, it is also set at the controllerTemperature control system. In addition, the wires are made from aviation wires and cannot be ignited by fire.

Graphene is incredibly durable and safe.
But is there really a market for graphene heating tiles?
This concern is not unreasonable. Because there is heating in the north in winter, the demand for heating tiles is not great; but in the south, the use of heating tiles is very rare. Haven't people been relying on "shaking" to survive the winter for so many years?
In order to solve the problem of air pollution in winter, on December 21, 2016, the 14th meeting of the Central Financial and Economic Leading Group issued Requirements for promoting clean heating in northern regions in winter .
The so-called clean heating refers to the use of natural gas, electricity (including various heat pumps), geothermal, biomass, solar energy , industrial waste heat, clean coal (ultra-low emission), nuclear energy and other clean energy sources, through high-efficiency energy-use systems to achieve low-emission, low-energy consumption heating methods. Electric heating is obviously one of the main methods.
As a new material tile with good heating effect, high safety performance, long service life, energy saving and environmental protection, graphene heating tiles should be one of the best products for clean heating.
my country’s electric heating area was only 400 million square meters in 2016. According to the national electric heating strategy, this figure will reach 1.5 billion square meters by 2021, almost four times the original! In the author’s opinion, southern compatriots are also likely to gradually accept heating tiles because of graphene’s durability and safety.
With such a huge market potential, graphene heating tiles have a bright future.
An industry veteran who did not allow the author to reveal his name once complained that the development of China's ceramic industry is becoming increasingly sluggish, and even product specifications can be used as a means of technological innovation to promote and hype. The implication is obvious, big slabs and rock slabsSpecification innovation cannot be called innovation in the true sense.
As I write this, I suddenly think of this guy’s argument. I wonder what he thinks of graphene heating tiles?
