1. Different heating materials. The heating element of carbon fiber electrothermal film is made of carbon fiber as conductor material. It is a new electrical, thermal and mechanical material with higher strength than steel, lower density than aluminum, more corrosion resistance than stainless steel, higher temperature resistance than heat-resistant steel, and can conduct electricity like copper.
Products are widely used in aerospace, sports equipment and medical equipment. Carbon crystal, in short, carbon crystal product is a kind of plate made of carbon particles as conductive materials and adhesives. The production of this product does not need any high-end technology and patents, and it is precisely for this reason that more than a dozen domestic manufacturers will emerge overnight.
2. The materials are different, so the production process is different, and the shape and thickness of the product are also different. Due to the fundamental differences in materials of heating elements, carbon crystals cannot produce products as light as carbon fiber electrothermal films. Carbon crystal is a plate-like product. What is the thickness of the plate? 8mm？ , its volume is large (40 * 90, 60 * 90, 60 * 280 ㎝) and its weight is heavy, which is not convenient for carrying and construction, and even more invisibly increases the load on the floor of users' homes.
And the thickness of carbon fiber electrothermal film is less than 1mm? As thin as a piece of paper. Convenient transportation and installation. At present, carbon fiber electric heating film products can not be produced in China, and only South Korea can produce them internationally. Carbon fiber electric heating film occupies about 70% market share in Korea. Although the carbon fiber electric heating film is light and thin, it has high technical content and high safety and stability. Products sell well 16 countries and regions.
3. The length of time for the product to go on the market and the length of warranty. Carbon fiber electric heating film products have a long history of several decades, occupying about 70% of the market in Korea. Products sell well in the United States, Japan, Russia and other countries and regions, and have passed many international certifications.
Carbon crystal products are by-products produced in the process of manufacturing carbon fibers, with low technical content and short use history. And because there is no technical content, over the past year or so, dozens of factories, large and small, have sprung up in China.
4. There is a big difference between price and price: carbon crystals are sold by pieces, ranging from 280-320 yuan per piece, but selling carbon powder and binder at this price is profiteering.
Although the process of carbon fiber electrothermal film is complicated, the price per square meter of heating area is lower than that of carbon crystal, and it is a product with high cost performance.
5. Different heating principles lead to different life spans. The most intuitive contrast between carbon crystal plate and carbon fiber plate is obvious.
The best way to distinguish is to look directly at the light and see the carbon fiber with network structure, which is granular carbon crystal floor heating.
Carbon crystal electric heating plate:
Carbon crystal electric heating plate is a "carbon crystal electric heating low temperature radiation heating system". It is a new type of low-temperature radiant heating system with carbon crystal heating plate as the core component, which has the advantages of long service life, high thermal efficiency, uniform heat dissipation and rapid temperature rise.
The heating principle of carbon crystal electric heating plate is that under the action of alternating electric field, carbon atoms in carbon crystal electric heating plate collide and rub violently, producing a lot of heat energy, which is transmitted to the outside in the form of far infrared radiation, and the conversion rate of electric energy and heat energy is over 98%.
Carbon fiber:
Carbon fiber (carbon? Fiber is a new fiber material with high strength and high modulus, and its carbon content is above 95%. It is a microcrystalline graphite material made of organic fibers such as flaky graphite microcrystals piled up along the fiber axis and carbonized and graphitized.
Carbon fiber is "soft outside and rigid inside", which is lighter than aluminum, but stronger than steel, and has the characteristics of corrosion resistance and high modulus. It is an important material for national defense, military industry and civil use. It not only has the inherent characteristics of carbon materials, but also has the softness and machinability of textile fibers, and is a new generation of reinforced fibers.
Carbon fiber can be divided into polyacrylonitrile-based carbon fiber, pitch-based carbon fiber, viscose-based carbon fiber, phenolic-based carbon fiber and vapor-grown carbon fiber according to the source of raw materials. According to the performance, it can be divided into ordinary carbon fiber, high strength carbon fiber, medium strength carbon fiber, high modulus carbon fiber and ultra-high modulus carbon fiber. According to the state, it is divided into filament, short fiber and short fiber; According to mechanical properties, it can be divided into general type and high performance type.
