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.

Abstract

The invention discloses a preparation method of porous corundum ceramics for a heating atomizer. The preparation method comprises the following steps: (1) weighing raw materials according to the following proportions: corundum 40-70wt%, adhesive 10-30wt%, and sintering 10-30wt% auxiliary agent, 10-30wt% pore-forming agent; (2) put the above-mentioned raw materials into the mixing equipment to obtain a slurry; (3) spray-dry the ceramic slurry to granulate; (4) granulate the ceramic (5) put the green body into a sintering furnace for sintering; (6) soak the porous ceramics with edible acid solution, wash and dry. The method uses carbon powder and organic pore-forming agent to control pore size and porosity. Clay and glass powder are used as sintering aids to sinter the corundum body. Porous ceramics have a super-affinity effect on water-based and alcohol-based liquids, and high porosity is prepared. , High-strength, fast-absorbing porous corundum ceramics.

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...
