The structure of the UV curing machine is relatively simple, with the key functions being LED lights and light guide rods, followed by the quality of the electronic controller.
A good light curing machine's LED light must have a narrow wavelength error range, preferably between 450nm-480nm of cold light (blue light); The LED light source specially designed for dental light curing machines developed by Silver Moonlight Technology has a peak wavelength of 460nm, paired with a 395nm wavelength band, allowing dental repair resin materials to quickly solidify under the action of light waves, making it the best LED light source choice; Secondly, LED lights can maintain their original light intensity during prolonged operation; Once again, there is a strong light intensity when the color temperature is low.
Research has shown that the mechanical strength of photo cured photosensitive resins is related to the number of cross linked long chain macromolecules in the resin. The more the number, the better the mechanical properties.
The recommended method is to use weak light guidance. Initially, lower light intensity is beneficial for the movement of molecules in the resin and the formation of long chain macromolecules. Later, high light intensity is used for rapid curing to achieve the best curing effect.
