Porous corundum ceramics used for heating atomizer and production method of porous corundum ceramics used for heating atomizer

Abstract

The invention discloses a production method of porous corundum ceramics used for a heating atomizer. The production method of the porous corundum ceramics used for the heating atomizer comprises the following steps: (1) weighing the raw materials according to the following proportions: 40-70 wt% of corundum, 10-30 wt% of adhesive, 10-30 wt% of sintering aids and 10-30 wt% of pore-forming agents; (2) putting the raw materials into mixing equipment to obtain slurry; (3) conducting spray drying granulation on the ceramic slurry; (4) placing granulated ceramics into a mould, and conducting dry pressing to obtain a green body; (5) placing the green body into a sintering furnace for sintering; and (6) soaking porous ceramics by adopting an edible acid solution, and conducting drying after cleaning is conducted. According to the method, carbon powder and an organic pore-forming agent are adopted for controlling the pore size and the porosity, clay and glass powder are used as the sintering aids for sintering a corundum main body, the porous ceramics have a super-hydrophilic effect on water-based liquid and alcohol-based liquid, and the porous corundum ceramics which have high porosity andhigh strength and absorb liquid fast are produced.

Description

technical field [0001] The invention relates to the field of ceramics, in particular to a porous corundum ceramic for a heating atomizer and a preparation method thereof. Background technique [0002] The atomizer is a device for atomizing liquid, which requires stable atomization effect, small, uniform and high atomization efficiency. The field of nebulizer is very wide. For example, it is used in medical treatment to atomize medicinal liquid and directly apply medicine to the patient's respiratory tract and lungs. It is a treatment method with outstanding advantages in the treatment of respiratory diseases; , to humidify the air and improve air quality; applied to aromatherapy and liquid mosquito-repellent incense, atomize water-based essential oil or mosquito-repellent liquid, and spread it to the indoor space to adjust the atmosphere and repel mosquitoes; It can replace traditional tobacco and reduce harm; it is also used in other fields: such as hairspray equipment for...

Problems solved by technology

[0004] The current porous ceramics for heating atomizers are mainly processed and produced by hot die-casting technology. It uses silicon bath soil, quartz sand, etc. It is sintered at 900°C. However, the porous ceramics produced by this method have low compressive strength, are easy to damage and drop slag, and the speed of absorbing liquid medicine or other atomized liquids is slow, and the atomization effect is insufficient.
