What's the difference between carbon crystal and carbon fiber?

Carbon is a widely used element, which has the advantage of high conversion efficiency (above 96%) when applied to heating materials. Therefore, it has developed rapidly and produced a lot of products, which is dazzling. This paper focuses on the differences, advantages and disadvantages between carbon crystal and carbon fiber. \x0d\ Let's look at carbon crystals first. The word carbon crystal only appeared in recent five or six years. The word carbon crystal is not found in national publications and industrial technical documents, which is mainly created by manufacturers for publicity needs. What the hell is this? Carbon crystals, in the form of carbon crystal bricks and carbon crystal plates, are used in the floor heating layer as a heating source. Its structure is also very simple, that is, carbon particles and adhesive are evenly stirred, pressed into a plate or brick shape, electrodes are led out at both ends, and the outside is encapsulated with plastic. It is precisely because of the simple structure and low technical threshold that more than 100 carbon crystal manufacturers emerged overnight in China. Because it is carbon particles, the board or brick is generally thicker, more than 5 cm (thin heat is not enough); The service life is determined by the adhesive, and the aging of the adhesive causes the carbon particles to fall off and the circuit does not heat up; Without compression, compression will accelerate the shedding of carbon particles. Warm continental carbon crystal wall \x0d\ Advantages: 99% high efficiency, mainly far infrared heating; \x0d\ Disadvantages: not compressive, easy to fall off inside, causing local overheating. \x0d\ \x0d\ Look at carbon fiber. Carbon fiber is a new type of electrical, thermal and mechanical material. Its strength is higher than that of steel, its density is lower than that of aluminum, its corrosion resistance is higher than that of stainless steel, its heat resistance is higher than that of heat-resistant steel, and its electrical conductivity is similar to that of copper. Products are widely used in aerospace, national defense and military industry. \x0d\ Carbon fiber was only used in the military field before, which belongs to the technical sensitive category of state secrets. After the lifting of the ban, it has made rapid development in the civil field. Scientists synthesize carbon fiber into two kinds of insulating materials by hot pressing, and electrodes are led out at both ends to make carbon fiber heating chips, which mainly produce far infrared heat. The chip has the advantages of high thermal conversion rate of 98.68%, ultra-thin, thickness less than 1mm, good flexibility and long service life. \x0d\ At present, there are no more than ten kinds of carbon fiber heating chips in the world, but none in China, which is a real high-tech product. Most domestic heating chips are imported and then applied to floor heating. \x0d\ Advantages: high efficiency of 98%, mainly far infrared heating, long service life, small size and light weight; \x0d\ Disadvantages: Higher price. Carbon fiber electrothermal floor heating material \ x0d \ x0d \ carbon fiber heating floor is a kind of floor (or tile) with two functions of floor (or tile) and floor heating, which breaks through the shortcomings of traditional floor heating layer and floor layer separation, large heat loss from heat conduction distance, high occupied area and inconvenient maintenance. The advocator of heating floor-Nuanyile Thermal Energy Technology has applied for the national patent of this technology, and has taken the lead in developing ceramic heating floor series, solid wood heating floor series and polymer fiber PVC floor series in the world. The living room is paved with tiles and the bedroom with wooden floors, which is more in line with the decoration style of southerners. Because the heat source is built in the floor, it saves many intermediate links, saves the height of the floor, reduces the heat conduction distance and reduces the heat loss, so it is more energy-saving; Modular installation, more convenient and simple construction, floor heating and floor laying can be completed directly; Convenient maintenance, just replace the corresponding floor. \x0d\ Advantages: 1. Plane heating, uniform temperature, that is, heating at once; \x0d\ 2。 Floor heating/floor two in one, a product has two functions; \x0d\ 3。 The pavement is simple, does not occupy the floor height, and does not damage the ground; \x0d\ 4。 Intelligent, sub-regional, sub-room control, automatic constant temperature; \x0d\ 5。 Health, far infrared radiation, health, comfort, not dry; \x0d\ 6。 Energy saving, 0.0 16kWh/m2/ hour, 1/2 for air conditioning and1/3 for water heating; \x0d\ 7。 Safety, built-in 50-degree temperature limit switch on the floor, fully sealed waterproof and leak-proof design; \x0d\ 8。 Worry-free, maintenance-free, moisture-proof and bacteriostatic design, no deformation; \x0d\ 9。 Durable, carbon fiber heating chip life up to hundreds of thousands of hours, can be used for more than 35 years.
