Graphene is a two-dimensional crystal composed of carbon atoms with only one atomic thickness. It is the thinnest, strongest, and most electrically and thermally conductive new nanomaterial discovered so far. It is called "black gold."

  Graphene's high strength, superconducting thermal and superconducting properties determine the graphene material's outstanding properties such as rapid heating, high thermal conversion rate, stable properties, long service life, and uniform heating. Graphene material is the most ideal electric heating material today and represents the future of electric heating materials.

Graphene heating film principle

The heating principle is that after the electric heating film is energized, the carbon atoms and trace rare earth elements in the heating element produce Brownian motion under the action of the electric field, rub each other at high speed, and release far-infrared rays, which are absorbed by the human body and resonate with cells and water molecules in the body to generate heat. Thereby playing the role of heating and health care.

With unique preparation technology, graphene is evenly dispersed in high-temperature resistant molecular materials and prepared through water-phase film-forming technology. Graphene electric heating film can withstand working environments up to 180°C, with typical operating temperatures up to 120°C, and has excellent high temperature resistance and high voltage resistance (1500V). The electrothermal conversion rate is as high as over 99%, and it can emit far-infrared waves, the "light of life" that directly affects the human body.

For actual application scenarios, the stable operating temperature and power of the electric heating film can be freely designed to fully meet the needs of various application scenarios for home heating. Compared with the traditional (air convection type with relatively low heating efficiency) heating method, the graphene heating film can achieve rapid heating in 10 seconds, has higher heating efficiency, better body feeling, and is more energy-saving.

After testing by the national authoritative department, the working life can reach more than 300,000 hours in extreme environments, and it has extremely strong working stability. It fills the gap in the application of graphene in home heating, has excellent properties such as energy saving, stability, safety, and environmental protection, and raises the technical level of home heating building materials to an unprecedented level.

6 advantages of choosing graphene heating

First, save money

Take an individual household with a building area of 100m² as an example:

Graphene heating: heating area: 100*75% (removing wall area and pool area) - 4 (one bathroom) = 71m²

The building is calculated based on 135W/m², which is: 71m²*135W/m²=9585W=9.585KW,

It takes 40 minutes to raise the temperature from 10-18, and it takes 30 minutes to raise the temperature by 1 degree every 5 minutes. It takes 30 minutes to lower the temperature by 1 degree. One cycle is 35 minutes.

If it is turned on only once a day: 24 hours - 40 minutes = 1400 minutes.

Calculating the rising and falling temperature as 1 degree, the number of cycles per day is: 1400 minutes/35 minutes = 40 times,

Pure heating time per day: 40 times * 5 minutes + 40 minutes = 240 minutes / 60 minutes = 4 hours,

At 0.5 yuan per kilowatt hour, electricity consumption per day: 9.585KW*4 hours*0.5 yuan=19.17 yuan. 19.17*30 days in a month=575 yuan.

Heating in Shenyang area lasts for five months in winter, and the operating electricity cost is 2,875 yuan.

During this period, 10-50% of us have no one at home, and 10-50% of the sun shines during this May. We calculate based on the minimum:

2875*80%=2300 yuan, and central heating will not reduce heating costs because there is no one at home or whether the weather is good or bad.

Central heating: Heating fees are charged according to the building area: 100m²*23.3 yuan/m²=2330 yuan

Second, safety

Thermal products have a service life of up to 50 years. Once installed, they have the same lifespan as the building and have a 10-year warranty.

The normal working temperature of graphene electric heating film is 40-50 degrees, and the maximum working temperature is 60°C.

The graphene electric heating film is tested for IPX7 waterproofing before leaving the factory, which is IPX7: anti-immersion type. Even if it is immersed in water under specified conditions, water will not enter the interior.

The graphene electric heating film connection line adopts a super-sealed aviation connector to ensure that it will not be corroded by water and is safe and worry-free.

Third, you can control it freely and do whatever you want.

After the graphene floor heating is installed, the only thing exposed is the thermostat. You can program it as you like, arrange the room temperature every day, and set your favorite comfortable temperature in each room. When you leave the room, you can also use your mobile phone to remotely control and enjoy a new experience in smart home life. No more hassle from heating companies, hot and cold autonomy.

No matter it is the heating season or the non-heating season, no matter what happens, I have a warm home that feels like spring all year round.

Fourth, comfort and health

The heating method of "heating the feet and cooling the head" from bottom to top, with even heat starting from the soles of the feet, is more suitable for the heating needs of the human body.

The heating principle of graphene electric heating film: Under the action of the electric field, the carbon atom groups in the heating element produce "Brownian motion", and violent friction and collision occur between the carbon atoms, and the generated heat energy is transferred to the outside in the form of far-infrared radiation and convection. , its electrical energy and thermal energy conversion rate is as high as over 99%

It has been measured that the human body is a heating body, and the peak value of the far-infrared band released is concentrated at around 9.5 microns, which is consistent with the far-infrared wavelength released by our products when they are working, which causes the resonance of human cells and water molecules to generate heat, making it as warm and comfortable as basking in the sun. . Far-infrared rays are also called the "light of life" because they have health-care and physical therapy effects.

Fifth, fast, convenient and noiseless

 It heats up instantly, quickly warms the room, and heats up quickly. After 5 to 15 minutes of powering on, the floor surface can reach a comfortable temperature that the human body can feel. Graphene electric floor heating operates noiselessly and quietly and slowly. you provide heat

Sixth, in line with the national environmental protection strategy and energy strategy

Gradually cancel the burning of coal for heating, significantly reduce the scattered burning of coal, implement and promote coal-to-electricity projects, and transform into clean energy. On September 28, 2016, the Liaoning Provincial Price Bureau, the Liaoning Provincial Industry and Information Technology Commission, and the Liaoning Provincial Department of Finance jointly issued the "Notice on Household Electricity Prices for Coal-to-Electric Heating Projects", pointing out that the household electricity prices for coal-to-electric heating projects will be implemented The peak and valley time-of-use electricity price policy will extend the peak period of electricity consumption from the original 7 hours (22:00-5:00) to 10 hours (21:00-7:00). The door-to-door electricity prices for electric heating projects are divided into residential electric heating prices and non-residential electric heating prices. Calculated based on the current on-grid transaction price of nuclear power: the household electricity price for residential heating is: 0.2798 yuan/kWh in the valley section; 0.4898 yuan/kWh in the flat section. For the electricity consumption of coal-to-electricity heating projects, the financial departments of each city must provide a price subsidy of no less than 0.011 yuan per kilowatt-hour. Electricity price policies vary from place to place, but stable subsidies and preferential treatment are the trend.
