Novel porous ceramic atomizing core production process

Abstract

The invention relates to the technical field of porous ceramic atomization core production, and discloses a novel porous ceramic atomization core production process, which comprises the following steps: mixing SiO2, Al2O3, Na2CO3 and CaCO3 powder, pore-forming powder and water, adding a binder, stirring, in the stirring process, the pore-forming powder comprises graphite, starch and plastic particles, the addition amount of the pore-forming powder is 10-50% of the total mass of the powder, and the binder is a binder; taking out the stirred mixed slurry, uniformly drying to obtain a ceramic dry body, uniformly crushing the dried ceramic dry body, uniformly dispersing the crushed ceramic dry body to obtain ceramic granulation powder, and then performing dry pressing on the ceramic granulation powder obtained after crushing. The invention relates to a novel porous ceramic atomization core production process, provides a design thought of a ceramic atomization core, and greatly simplifies the development period of ceramic and stabilizes the atomization performance of the ceramic by controlling the porosity and aperture of the ceramic and matching with the oil seepage distance of the corresponding atomization core.

Description

technical field [0001] The invention relates to the technical field of production of porous ceramic atomizing cores, in particular to a novel production process of porous ceramic atomizing cores. Background technique [0002] The electronic cigarette ceramic atomizing core is the core component of the electronic cigarette. The main components of the ceramic atomizing core are derived from nature. After high-temperature firing, many small holes are formed inside, and the average pore size is equivalent to one-fifth of a hair. , These tiny micropores are the key to the stable liquid guiding and liquid locking function of the ceramic atomizing core. Due to surface tension and capillary action, the liquid can evenly penetrate into the atomizing core and adsorb on the surface of the atomizing core, and the porous ceramic material has strong adsorption and very good biocompatibility. The atomization performance of the electronic cigarette is improved, and the ceramic matrix of th...

Problems solved by technology

[0003] In the current existing system, the porosity and pore size of ceramics are the key to material design. If the porosity is too low, the oil seepage is insufficient, and the core will easily burn. If the porosity is too high, the ceramics will easily have insufficient oil-holding capacity. ; There are similar problems in the size of the aperture, that is, the problem of small aperture and insufficient fugue speed, and the atomization cores currently on the market, according to different ceramic designs, especially the difference in the oil seepage distance of ceramics, adjust the porosity and aperture of ceramics To match the corresponding atomizing core structure, but in this process, the lack of corresponding design ideas often results in a mismatch between the designed ceramic porosity and pore size, which not only greatly increases the ceramic development cycle, but also affects product yield and Prepare the stability of the pod vaping experience
