What is the porous ceramic atomizing core of the electronic cigarette? In recent years, new materials whose surface and interface play a prominent role have been paid more and more attention. Porous ceramic material is a new type of material that utilizes the physical surface. It is a ceramic body with a three-dimensional network skeleton structure that is fired at high temperature and has a large number of three-dimensional interconnected channels. This new type of porous ceramic material plays an extremely important role in the atomization process of electronic cigarettes.
RELX is the first pod vape in China that uses the Smoore FEELM heating element. The atomizing core used by RELX is a ceramic atomizing heating element, which has the characteristics of stable high temperature resistance, safety and easy oil conduction, and can bring a more delicate taste and the advantages of oil leakage prevention. At present, the microporous ceramic atomizing core is the standard configuration of e-liquid e-cigarettes, in addition to MK e-cigarettes, NRX Niwei, MT and other e-cigarettes. How is this porous ceramic with three-dimensional network skeleton structure produced? There are many types of porous ceramic materials. Due to the different purposes of use, the properties of the materials are also different. Therefore, many different preparation technologies have been gradually developed in recent years. The general preparation process of porous ceramics is granulation, mixing, molding, sintering, etc.
The pore-forming method of porous ceramics mainly lies in the formation of pores during the sintering process. The pore-forming methods include adding pore-forming agents, foaming processes, organic foam impregnation processes, and sol-gel processes. 1. The process of adding pore-forming agent is to add a pore-forming agent to the ceramic ingredients, and use the pore-forming agent to occupy a certain space in the green body. During the sintering process, the pore-forming agent leaves the matrix to form pores to obtain porous ceramics. Molding methods mainly include molding, extrusion, rolling, isostatic pressing, injection and slip casting. Products are generally referred to as cellular porous ceramics. 2. Organic foam impregnation The ceramic slurry is impregnated with organic foam, and the organic foam is burned off after drying to obtain porous ceramics. This method is suitable for preparing porous ceramics with high porosity and open pores. Products are generally referred to as mesh porous ceramics. 3. Foaming method The foaming agent is mixed with the clay material, and the clay particles are bonded to each other under pressure. When enough heat is transferred to the inside of the clay particles, the material expands and fills the entire mold, and becomes porous after cooling. Ceramic material. Porous ceramics with various pore sizes and shapes can be prepared, which are generally called foamed porous ceramics. 4. Sol-gel process Ceramic particles and organic gel are mixed, cleaned and ion-exchanged, and sintered into a porous ceramic material. The structure, porosity and pore size of porous SiO2 materials can be changed by adjusting the sintering temperature. The sol-gel method is mainly used to prepare microporous ceramic materials, especially microporous ceramic films. Comparison of Several Processes
Among them, the application is more successful, and the more active research is to add volatile or combustible pore-forming agents to the ceramic ingredients, and use these pore-forming agents to volatilize or burn out at high temperatures to leave pores in the ceramic body. According to the pore size, ceramics can be divided into 1000μCoarse porous products from m to tens of microns, 0.2~20μm microporous products and 0.2μUltra-microporous products from m to several nanometers. According to the pore-forming method and void, porous ceramics can be divided into: foam ceramics, honeycomb ceramics, and granular ceramics. The corresponding porosity is as follows:
The precise control of the preparation technology on the porous ceramic structure, including the size, shape and distribution of the affected pores, has different effects. The connection strength between aggregate particles determines the strength of porous ceramics, and the relationship between porosity and strength needs to be reasonably coordinated. Due to high porosity, low density and low thermal conductivity, porous ceramics have huge thermal resistance and small volumetric heat capacity. Porous ceramic materials have been used in various fields such as metallurgy, chemical industry, environmental protection, energy, and biology. In addition to the space shuttle shell insulation, missile heads, filters, etc. that we generally know, they are also playing a huge role in the field of electronic cigarettes. Ceramic atomizing core is the standard configuration of high-quality e-cigarette pods at present. It adopts a porous ceramic structure, and its pore size is generally micron or submicron. It is generally called a microporous ceramic atomizing core. In addition to the atomizing core, there is another type of ceramic oil guide tube, which also uses porous ceramics.
