[UVLED point Light source] Curing machine is a small and flexible device, compared with line and surface light sources, smaller volume, suitable for smaller devices and small area glue curing applications, such as mobile phone camera modules. Auvcure has many mobile device customers who are using UVLED electric light curing machines.
UVLED point light source curing machine selection needs to consider these factors
In choosing a suitable UVLED point light source curing machine, in addition to the usual photoinitiator activity and concentration, monomer reactivity (reactive group structure, functionality, monomer structure) and the reactivity of the photocuring resin and radiation curing conditions (including light intensity, the distribution intensity of the main output wavelength of the light source, resistance oxygen inhibition measures, etc.), we also need to consider the following factors:
1. Influence of concentration and type of photoinitiator
The photoinitiator is the more critical part of the UV glue formulation. Too low concentration is not enough to produce a high curing speed, which is not conducive to resistance to oxygen inhibition; However, too high initiator concentration will lead to too much residual amount after photocuring, which will make the anti-yellowing and anti-aging properties of the cured film deteriorate, and the residual initiator is easier to precipitate from the cured film, affecting the appearance quality.
2. The role of diluent
Active diluents are used to reduce the viscosity of UV glue, thereby improving the performance of cured coatings. At the same time, the active diluent also has a significant effect on the photocuring process.
3.UV glue layer thickness
The thickness of the UV glue layer is very important for UVLED curing, which is limited by the viscosity of the paint and the painting process conditions. When the adhesive layer is thick, due to the photoinitiator itself, its broken fragments and the light absorption and shading of the resin, the underlying curing may be incomplete, thus affecting the overall performance of the bond.
4. Temperature effect
Appropriately increasing the temperature of the place where the UVLED curing machine is located helps to improve the curing speed of UV glue.
