Introduction to new materials of vape atomizing core ceramics: What are the advantages of SiC atomizing core?
Most of the pod vape atomizing cores on the market are made of corundum, diatomite or quartz mixed low-temperature glass powder, which is sintered at low temperature and has a white appearance. There are also black or gray atomization cores on the market. In fact, most of the white atomization cores are formed by adding color, coating or reduction firing, which is not the nature of ceramic raw materials.
It is understood that Smoore’s FEELM atomization core is made of corundum composite material. Corundum, the main component is alumina (Al2O3), and corundum atomization core can be obtained by low-temperature sintering of clay and glass powder. The manufacturing process is simple, but clay is not completely burnt at low temperature, and it will have an earthy smell, which will affect the taste. Although these problems can be solved by technological research and development, they also bring about problems such as high production cost and complex process, and the difficulty of mass production is relatively high.
In order to make up for the above difficulties of corundum material, some manufacturers in the industry have developed a silicon carbide material. Let’s take a look at this material.
Compared with corundum atomization core material, silicon carbide atomization core material has the following characteristics:
1. High temperature made ceramics
Compared with most low-temperature ceramic atomization cores on the market, it needs to be fired at 1300 degrees high temperature to produce higher degree of ceramics. When used in electronic cigarettes, burnt cores will not appear. And because the high-temperature burning is more thorough, the vapor atomization flavor is pure, and there will be no earthy smell or other odor, which will improve the experience of vape users.
2. The stomatal rate is higher and the taste is better.
The important characteristics of porous silicon carbide ceramics are more controllable pore size, micron pore size, high open porosity and uniformity of pore size distribution, which can make the vape emit more vapor, the flavor is delicate and the flavor fidelity is high.
3. High hardness
Silicon carbide atomization core is made of high-quality silicon carbide as main material, mixed with perlite, diatomite and other high-temperature sintering materials. Silicon carbide itself has very high hardness. During the calcination process, the boundary of raw material particles melts and bonds, forming a new type of porous ceramics with high strength and integrity, which is conducive to automatic assembly of mechanized materials. Moreover, through vibration and throwing treatment, the finished product will not have dust falling off, which effectively improves the safety and reliability of vapes.
4. More stable chemical feature
Silicon carbide porous ceramic material is acid-resistant, corrosion-resistant, can withstand high temperature, its own clean state is good, will not cause secondary pollution, is an environmental protection functional material. When used in electronic cigarette, it will not produce harmful substances to human body.
5. Good thermal conductivity
The low thermal conductivity of ceramic core is not conducive to the atomization of vape juice, resulting in inadequate atomization. The high thermal conductivity will lead to the boiling pot and vape juice explosion. If placed in vape, the high thermal conductivity will lead to the poor performance of the first two ports. The new silicon carbide atomization technology solves this problem well. Through special formulation, the product can achieve a good balance in thermal conductivity. It will work extremely fast when it enters the working state. Even in the cold state, the first two times of vaping will perform very well, and will not affect the user’s experience.
6. Vape juice lockability
The first second is to enjoy the pleasure of vaping and dancing, but the second is to inhale hot e-liquids. Nothing can destroy vapers ‘experience more than e-liquid leakage, which has always been the pain point in pod systems. Silicon carbide atomization technology makes use of its unique formula to lock the vape juice tightly, which can effectively control and reduce the occurrence of this situation and increase the reliability of products.
Ceramic Atomizing Core Made of Silicon Carbide Composite Material
Silicon carbide is a typical covalent bond material with high strength, high hardness, high thermal conductivity, low expansion, specific low weight and other features. It has good thermal strike resistance and corrosion resistance. Silicon carbide has been widely used in mechanical, chemical, energy, military and other fields due to its series of features. It has become the preferred material in many new fields including high-temperature applications and the focus of material scientists.
Selecting high-quality silicon carbide as the main material, then adding perlite, diatomite and other ingredients as the auxiliary material. Sintering at 1300 degrees temperature, a porous ceramic material with micron pore size and high open porosity can be obtained. At the same time, it has the characteristics of high temperature, high pressure, acid and alkali resistance, non-peculiar smell and corrosion resistance, and has good biological inertia.
At present, silicon carbide ceramics also have many technical bottlenecks, such as high energy consumption, poor thick film printing, and low proportion of silicon carbide. So how to achieve a balance in atomization, leakage proof and flavor fidelity? By high temperature sintering, the odor of ceramic core can be completely avoided with relatively simple production process, and it has certain advantages in controlling production cost, improving automation degree of mass production and reducing device investment cost.
