1. It is easy to heat up locally, and the heating ground cannot be covered. Once covered, the temperature of the covered area will continue to rise until it exceeds the safe temperature, damaging the wire, or even causing a fire.
2. The wire rod has poor fire resistance, and the wire rod is in a state of alternating cold and hot when working, and the anti-aging of the surface fireproof material of the commonly used wire system and the aging after long-term work have a certain impact on its fire resistance. Specific aging experiments have not been done, and there is no credible data. The fire resistance of the wire is limited, and the core material is generally flammable and has a fire point.
Once the wire is short-circuited or the local heating is uneven, it is easy to cause serious accidents.
3. High radiation due to the electromagnetic principle, whether it is a double core or a single core, there is a high radiation when working, although it can be reduced to a certain extent by technical means, but it still has a certain amount of harm to the human body, and the specific degree of damage has not been studied by organizations and institutions for the time being. Therefore, it is not suitable for families with pregnant women and children. It also has a certain impact on electronics.
4. Thermostat fault: The thermostat controls the heating rate and switch of the cable. Generally, a single wire can be about 20kw, and a few are even higher. For the sake of versatility, the thermostat is generally designed to be installed in a standard 86-wire box, which limits the size of the thermostat, and it is quite complicated to arrange high-power appliances in such a small space.
When the temperature control works for a long time, the ambient temperature is higher, which aggravates the aging degree of electronic components, and the wire generally has a metal shielding layer in order to prevent radiation, and this structure happens to form a primitive capacitance, at the moment of switching, the large current is easy to hurt the fragile electronic components, causing damage, and even accidents. This is caused by the structure of the system and cannot be effectively solved.

Carbon fiber is made by carbonization of natural fibers or man-made organic chemical fibers. Its main component is composed of carbon atoms. Another striking structure of carbon fiber is its well-developed specific surface area and abundant micropore size.
What is the principle of carbon fiber underfloor heating.
Carbon fiber underfloor heating uses electricity to obtain heat through the oscillation of carbon fiber molecule activity and Brownian motion. This type of heating makes full use of the three modes of heat propagation, namely: heat conduction, heat convection, and heat emission.
Carbon crystal floor heatingCarbon crystal floor heating system is a new type of ground low-temperature radiant heating system developed with carbon crystal heating plate as the main heating component. The carbon crystal floor heating system makes full use of the excellent plane heating characteristics of the carbon crystal plate, and the whole ground (flat) surface is heated synchronously during heating, continuous heating, and the ground heat balance effect is good. It overcomes the disadvantages of discontinuous heating and poor thermal balance effect of traditional floor heating products.
It is the best alternative to air conditioning and heating equipment and traditional boiler floor heating equipment, environmental protection and energy saving, low cost, convenient and fast installation and construction. It is an outstanding application of high-tech in the field of civil products, and it is an upgraded product in the floor heating industry.
Heating principle: The heating principle of carbon crystal floor heating is to lay the flat carbon crystal plate below the ground trim. Under the action of the electric field, the carbon crystal molecules move and friction to generate heat, which increases the temperature of the carbon crystal plate surface, and continuously transfers heat evenly to the floor or floor tile surface through the ground material close to the carbon crystal plate.
At the same time, the carbon crystal plate will generate a large amount of upward far-infrared waves to heat indoor objects.
The reason why the carbon crystal plate can quickly heat up the object is that 100% of its electrical energy input is effectively converted into more than 60% of the conductive heat energy and more than 30% of the infrared radiation energy. This dual heating principle makes the heated object: the first heats up faster, and the second absorbs more heat energy.
Heat conduction heating.
The flat carbon crystal plate is laid below the ground decoration material, and the carbon crystal plate generates heat energy through the movement of carbon crystal molecules and friction under the action of the electric field, so that the temperature of the carbon crystal plate surface increases, and continuously passes the covering of the carbon crystal plate and the thermal insulation material on the back of the carbon crystal electric heating material, and the thermal insulation material continuously reflects the heat energy to the covering on the surface of the heating element, so that the surface temperature rises. Qianyi carbon crystal floor heating has developed a 600*2800mm three-meter slab, which solves the problem that the carbon crystal board is too small in the past.
After only 2 to 4 minutes, the thermal equilibrium between the heating element and the thermal insulation material is reached, and the heat radiates at a constant temperature. The heated ground then slowly transfers heat energy to the air close to the ground in the room. Under the influence of the thermal engineering principle of "hot air is light, cold air is heavy", the air close to the ground rises rapidly after heating, and the cold air is constantly replenished to the ground to be heated and heated, and so on.
Finally, the vertical convection of the air up and down drives the increase of the indoor ambient temperature.

Carbon fiber and metal wire heat generation are mainly different in conduction mode, heating efficiency and service life.
1. Different conduction methods: carbon fiber is conducted to the human body through infrared rays, and heat energy is directly delivered to the tissues and organs of the human body. The heating of the metal wire is transmitted to the human body through heat conduction through a certain medium through the heating of the metal wire.
In contrast, the transfer of heat radiation is more comfortable for the human body.
2. Different heating efficiency: the biggest feature of carbon fiber heating is that it heats up quickly, and the electromagnetic radiation is very small, and the radiation amount of metal wire is relatively large. In comparison, the energy conversion efficiency of carbon fiber heating is much higher than that of metal wire heating, about 60% higher.
Therefore, carbon fiber heating is relatively more energy-saving.
3. The difference in service life: due to the innate characteristics of carbon fiber, its durability and corrosion resistance are more excellent. Comparatively speaking, metal heating wires are easy to age, corrode, and have a short service life.
Therefore, the service life of general carbon fiber is about 3-5 years, and the metal wire is only about 1-3 years.

1.Carbon fiber heat energy is not conducted through the medium, but far-infrared light waves are radiated to the inside of the human body, and the heat energy is directly delivered to the tissues and organs of the human body.
2.The biggest feature of carbon fiber heating is that the amount of electromagnetic radiation is extremely small, which is smaller than that of metal wire after electromagnetic wave shielding, which is harmless to the human body.
3.The heat conversion rate is about 60% higher.
4.Long life: Because of the characteristics of carbon fiber, it is corrosion-resistant and durable. The metal heating wire is easy to age, corrode, and has a short service life.
I have a friend who bought a warm carbon fiber far-infrared electric heater last year, the effect is different, I will also buy a few for the elderly at home this year!

It's really upstairs.。。。 People want to make heating stickers, what kind of heating tube do you advertise... fainted...
What does carbon fiber mean by fibrosis of carbon atoms? That is to say, carbon atoms have better plasticity after fibrosis and can be arbitrarily processed into various shapes.
Carbon fiber heating sheet, is a kind of sheet structure formed by carbon fiber after processing, can be quickly heated in a short time, with the effect of rapid heating, similar to "carbon fiber heating tube, carbon fiber heating cable, carbon fiber heating wire, etc.", but it should be noted that its heating principle is in short, it is the principle of quickly converting electrical energy into heat energy under the condition of electricity. So if the heating paste you want to develop is similar to a warm water handle that some children take in winter, and it is very hot when the electricity is turned on, you can base it on this material. But there is also a kind of heating paste is bagged, a thin piece, rubbed by hand and heated, the substrate of the heating paste is not carbon fiber, but a mixed chemical, depending on what kind of heating paste you want to develop, and what questions can you give me a speech.

Differences: 1. Carbon fiber specifications: 24K is composed of 24,000 carbon fiber filaments to form 1 bundle, 12K is composed of 12,000 carbon fiber filaments to form 1 bundle, 12K resistance value is between 33-36 ohms, and 24K resistance value is about half of 12K, because the resistance value is different, 24K will heat up faster.
2. Carbon fiber heating element is a pure blackbody material, so it has the characteristics of rapid heating, small thermal hysteresis, uniform heating, long heat radiation transmission distance, fast heat exchange speed, etc., carbon fiber heating is widely used in floor heating, heaters, heaters, bath bombs.
3. Carbon fiber is made of organic parent fibers (such as viscose wire, polyacrylonitrile or asphalt) to be removed by high temperature all elements, carbon fiber is black, hard, with high strength, light weight and other characteristics, is a new material with excellent mechanical properties.

The principle of carbon fiber heating: the same as the metal energized heating, carbon brazing can conduct electricity, there is resistance, then the electricity through the carbon brazing when it encounters resistance will heat up, the higher the resistance, the faster the heating.
Difference: A 12k carbon fiber bundle has less resistance than a 24k carbon fiber bundle, so it doesn't heat up as fast as a 24k one.
-
Principle: Carbon fiber is a conductor, and the heating principle is the same as that of aluminum wire and copper wire. The difference is that carbon fiber can emit far infrared rays during the heating process, which is very beneficial to human health (far infrared is called the light of life of the human body by the medical community).
Difference Between 24k and 12k Carbon Fiber:
1. The heating principle of carbon fiber: when the voltage is applied at both ends of the filament carbon fiber, the carbon molecules in the filament carbon fiber do hot Brownian motion under the action of electromotive force, and the carbon molecules generate heat when they collide with each other during the movement, and when there are many carbon molecules in the heating element, the more intense the hot Brownian motion produces more heat; Therefore, the electrothermal conversion capacity of 24k is better than that of the lower k number.
2. The tensile strength of carbon fiber is 8 times that of the same steel, and its tensile strength increases geometrically when the carbon fiber bundle increases. In this way, it can be a good damage to the carbon fiber caused by pulling during on-site construction.
3. The increase of carbon fiber bundle also increases the heat dissipation area of the heating element, and dissipates more heat generated to achieve the purpose of energy-saving heating.
4. The increase of carbon fiber bundle makes it possible to make the line length longer and the power larger under the same line power (12k generally uses meters 150w, 24k generally uses meters 230w); This reduces the amount of carbon fiber joints in the same power in the room, and also reduces safety hazards.
Carbon fiber electric floor heating, according to the inherent characteristics of its carbon material, but also has the porous and capricious nature of textile materials, multi-faceted, pressurized and conductive at both ends, so that the electric energy is quickly converted into heat energy, and the heat is dissipated through far infrared radiation to achieve the heating effect, which is the working principle of carbon fiber electric floor heating. Because its heating effect is very good, so more and more people use it, in Beijing, there is a Hengsheng Xingyuan is the production of carbon fiber electric floor heating.
