The atomizer 51 can adopt a suction-type atomization structure, and the jet air pressure and the outlet of the light-cured material can be manually adjusted or the flow rate can be controlled by controlling the aperture of the air flow through a micro motor, so that atomization inspection can be conveniently carried out before work, and the spray atomization effect can be regulated and controlled. The thickness of the primary spraying can be 0.04-0.06 mm, and preferably 0.05 mm.
The photosensitive nano raw material is prepared from 30-60% of vinyl-containing polymer (such as unsaturated polyester, acrylic polymer and the like) as a base material, 40-60% of active monomer as a cross-linking agent (active diluent), 1-5% of easily photodegradable compound as a photosensitizer and 0.2-0.5% of other auxiliary materials. Curing by ultraviolet light irradiation to cause generation of a traveling radical reaction. The mixing of 0.5% cellulose as an auxiliary material increases the elasticity and flexibility of the shell, and the mixing of 0.2% titanium powder as an auxiliary material increases the corrosion resistance and crack resistance of the shell, making the shell thinner.
S3, enabling the atomizing nozzle 51 to leave the ear-like female die 3 and the closed chamber 1, starting the ultraviolet lamp 4 to irradiate the photosensitive nano raw material in the ear-like female die 3 and curing the photosensitive nano raw material to obtain a thin-wall shell;
s4, repeating the steps S2 and S3 until the shell reaches the preset thickness, cutting the gypsum and taking out the shell to obtain the finished product. The number of spraying times can be selected to be 3-6 times according to needs. The final thickness of the shell is 0.2-0.3 mm, and the thickness of the shell on the market is generally 0.4-0.5 mm.
The outer wall of the shell manufactured by the ear canal shape modeling manufacturing method completely conforms to the shape of a male die, and is smooth and not bad; the photocuring material can be mixed with other pigments to customize the color, so that the aesthetic and individual requirements are increased; has good fitting property with human ears. And the shell cavity is used for placing components, the total time of each atomization and photocuring which does not require good fault tolerance on the inner wall surface is not more than 2 minutes, and the shell manufacturing time is greatly reduced.
