2results about How to "Improve light curing efficiency" patented technology

The utility model belongs to the technical field of optical fiber processing equipment, in particular to optical fiber connector curing equipment, which comprises a workbench and a UVLED (Ultraviolet Light Emitting Diode) light source arranged above the workbench, and further comprises a clamping mechanism which comprises a movable seat movably connected to the workbench; the fixed vertical plate is fixed on the top surface of the movable seat; the multiple pneumatic clamping jaws are distributed in the horizontal direction at equal intervals and rotationally connected to the fixed vertical plate; the rotary power assembly is used for driving the pneumatic clamping jaw to rotate; the translation power assembly is used for driving the clamping mechanism to move horizontally; according to the utility model, through the rotation of the pneumatic clamping jaw and the translation of the clamping mechanism, the optical fiber connector is exposed under the UVLED light source in all directions, the irradiation blind area is eliminated, and the photocuring efficiency is obviously improved.

This invention belongs to the field of photocurable polymer materials technology, specifically relating to a high-strength, wear-resistant resin composition and artificial nails. The composition comprises the following components in the indicated proportions: 100 parts by weight of modified polyurethane acrylate, 50-150 parts by weight of reactive diluent monomer, and 1-10 parts by weight of photoinitiator. The modified polyurethane acrylate is obtained by first-step carbamate reaction of cyclohexanehexyl alcohol with alicyclic or aromatic diisocyanate to obtain an isocyanate-terminated oligomer, followed by a second-step carbamate reaction with (meth)acrylate hydroxyl ester, resulting in a hexafunctional polyurethane acrylate with a clustered dispersion structure. Compared to conventional multifunctional polyurethane acrylates, the resulting composition exhibits higher photocuring efficiency, and the artificial nails prepared after curing have higher strength and wear resistance.
