The two characteristics of true carbon crystals are as follows: First, microcrystalline particle heating element of carbon element, not carbon ink and carbon fiber heating element, and secondly, rigid epoxy resin PCB board is used as a temperature-resistant insulation package, and is not a soft PET. Films or other packaging materials.
Pseudocarbon crystals: More than 90% of so-called "carbon crystals" on the market are counterfeit. One is the electrothermal film known as carbon crystal, regardless of the internal heating material is helium, as long as it is a soft heating element is absolutely not a carbon crystal; one is a carbon fiber board packaged with a rigid insulation board, the appearance is similar to the carbon crystal plate, there is The intention is to cover up the surface by pressing a layer of black paper or floor pattern paper. The internal heating material of the heating plate is carbon fiber paper (using short carbon fiber yarn and pulp to make heat conductive paper). The identification method is: The light has a hairline-like substance that is visually detected. The defect is that the surface is not evenly heated, and the high-temperature spots in the densely-dispersed portion (easily burned for prolonged use) are difficult to meet the national standards for the infrared heater surface temperature difference below 7 degrees, although it is known as 50 Annual life, it is practically difficult to run without fault for more than 10 years; there is also a direct use of carbon fiber paper, without the use of insulating packaging materials, it is done inside the composite product, this false home of the so-called carbon crystal is completely insulated and not waterproof, It is easily damaged by moisture and its service life is less than 3 years. As long as there is a product that has burned or leaked, it can be judged that it is not carbon crystal.
