Large space disinfection and sterilization, medical beauty, consumer electronic atomizers... With more and more use scenarios, the electronic atomization industry is gradually becoming a new 100 billion level market.

As the core component of electronic atomizers, the atomizer core has always been a battleground in China's electronic atomization industry, driving round after round of technological innovation and industry transformation.

Iteration has been occurring in the atomization core technology. From the earliest fiberglass core to resistance cotton core to ceramic atomization core, the atomization core has undergone several changes, and the requirements for heating uniformity, ceramic strength, and ceramic atomization energy efficiency continue to increase. However, currently mainstream ceramic atomization cores on the market generally face a series of problems:

Firstly, sufficient oil conductivity requires a larger porosity and smaller ceramic fiber aperture, but it will affect the strength of the ceramic atomization core; On the other hand, in order to ensure taste, a sufficiently small ceramic fiber aperture is required, and existing ceramic materials are difficult to achieve this balance. In addition, ceramic sintering and surface metallization methods also face many technical challenges in the implementation process

Faced with these pain points, newly entered enterprises are constantly striving for innovation and exploring breakthroughs.

The reporter noticed that Bauhinia Future Technology Co., Ltd. (hereinafter referred to as "Bauhinia Future Technology"), located in "Fog Valley" Shenzhen, proposed the latest technological concept - SiC aerogel ceramic atomizing core (hereinafter referred to as "aerogel ceramic atomizing core"), and is becoming the next enterprise worthy of attention in the field of atomization with its strong scientific research strength.

Preparation of aerogel ceramics+core material sintering

Create the first international aerogel ceramic atomizing core

At present, Zijing Future Technology is focusing on in-depth research on cutting-edge new materials and atomization technologies, and applying new materials and technologies to various atomization scenarios. Among them, aerogel ceramic functional materials are the important achievements of the company in recent years.

The first SiC aerogel ceramic atomizing core in the world

"The world's first aerogel ceramic atomizing core developed by us will bring a new technical concept to the atomizing core product. This atomizing core can use the whole surface coating electrode technology to eliminate the printing electrode, with uniform and stable heating and fogging droplet D90 diameter<1.65 μ m. " Wu Haiming, founder of Zijing Future Technology, said.

Why does the aerogel ceramic atomizing core become the next highland of atomizing core and lead the industry to a new stage of development? With such questions, the reporter came to the Zijing Future Science and Technology Office in Longgang District, Shenzhen, and told Wu Haiming about the five core technologies behind the Jieqi gel ceramic atomization core in detail:

"At this stage, the revolutionary breakthrough of aerogel ceramic core largely depends on the preparation technology of aerogel ceramic core," he said, "The traditional atomization technology needs wax for pore forming. The pores of the traditional ceramic core after sintering are like worms, which leads to inconsistent pores and powder loss problems, poor taste reduction, oil leakage and powder precipitation. The air gel functional ceramic technology mastered by Bauhinia in the future, the pores after sintering are all in line, and the porosity can be as high as 85%. It is like three lanes have become eight lanes, and the circulation of smoke oil is large Increase in amplitude. At the same time, we can also reduce the circulation of tobacco oil by closing some of the pores, which means we can adjust flexibly as needed

Secondly, it is the core material sintering reinforcement technology. At present, the pore structure of ceramic cores on the market reaches 65% to the extreme. No matter how high the pore rate is, it becomes brittle and unformed, and is prone to burning and collapse. The airflow is like the throttle of an atomizer. The larger the airflow, the faster the instantaneous temperature rise, while the smaller the airflow, the slower the temperature rise. The aerogel ceramic atomization core of Bauhinia Future Technology has different boiling points and atomization points for different industries and different smoke oils. "In terms of air to mist ratio, for example, the smoke that is pushed in and then atomized at high temperature can control the airflow and mist volume, resulting in a better taste and experience. It will not be too strong to be choking or too light to be tasteless," said Wu Haiming.

The first SiC aerogel ceramic atomizing core in the world

At present, the most common mesh shaped heating wire on the market is prone to scabbing and blockage during use. Zijing Future Technology adopts liquid metal printing technology to change the shape of the heating wire and pour liquid metal onto the ceramic atomization core, making it block shaped. The liquid metal can be firmly embedded in the fiber in high temperature environments, solving the problem of precise temperature control of ceramics.

Wu Haiming explained, "If the ceramic pores are not enough, the ceramic poured with metal is like an ant nest filled with water, and the structure is pulled down into particles. We need the metal to penetrate into the fiber pores of the ceramic while adhering to it without falling off blocks. Due to the different densities of metal and ceramic, their ability to withstand high temperatures during integrated sintering is also different, which is a difficult technology to master."

The packaging and cutting technology of Bauhinia Future Technology is precisely a clever way to respond to customer needs in a timely manner. Wu Haiming said, "With strong design capabilities, we can quickly customize the thin thickness of grooves according to customer specific needs, and flexibly adjust them through packaging and cutting. For example, the atomization core oil groove can be personalized and matched, and the size of smoke volume can be adjusted according to customer needs."

It is worth mentioning that Zijing Future Technology adopts a simulation structure design on the atomization core. By testing and calculating the respiratory capacity of different states and age groups, simulating digital simulation results, and optimizing the structural parameters of the atomization core, it is applied in the sensor part to precisely control the number of large and small air holes and various data, in order to improve atomization efficiency, reduce harmful substance generation, and improve taste.

Micropore Morphology of Aerogel Ceramic Atomizing Core

Through mature and perfect process, the air gel ceramic atomization core of Bauhinia Future Technology has reached the international leading level, and has achieved subversive results in the atomizer industry: the air gel brittleness has been reduced, and the problem of "powder loss" has been solved; The maximum use temperature is 1500 ℃, which is much higher than the upper limit of the use temperature of conventional aerogel, 650 ℃; Has significantly higher mechanical strength while still maintaining excellent compressibility/resilience; Under the condition of high strength, the porosity is increased by 30% compared with the existing market products, and the taste is more delicate than the existing products... The pain points of the five key links of the "air, fog, oil, temperature, and electricity" atomization core are solved in one step. The aerogel ceramic atomization core further strengthens the dominant position of Bauhinia chinensis in the future technology of atomization core.
