为了提高复合贴面材料的后固化性能，研制了一种高强度的实验室光固化装置。本研究介绍了固化单元的结构，并检查了具有代表性的复合材料的性能。固化单元配备有两个金属卤化物灯，辐射紫外线和可见光。与用于工业用途的常规金属卤化物灯不同，这些金属卤化物灯辐射增加强度的可见辐射。确定了用新的金属卤化物单元固化的微填充复合贴面材料的性能。氙光固化单元也用作对照。与氙单元固化的样品相比，用金属卤化物单元固化的样品表现出更大的努普硬度值和弯曲模量，并且还表现出降低的水溶性值。这些结果表明，金属卤化物光源在较短的时间内固化复合材料是有效的，并且具有改善的转化率。
A high-intensity laboratory photo-curing unit has been developed with the aim of improving the post-curing properties of composite veneering materials. This study introduces the structure of the curing unit and examines the resulting properties of a representative composite material. The curing unit is equipped with two metal halide lamps that radiate both ultraviolet and visible light. Unlike conventional metal halide lamps for industrial use, these metal halide lamps radiate an increased intensity of visible radiation. Properties of a microfilled composite veneering material cured with the new metal halide unit were ascertained. A xenon photo-curing unit was also used as a control. The specimens cured with the metal halide unit exhibited greater Knoop hardness numbers and flexural moduli as compared with those cured with the xenon unit, and also showed reduced water solubility values. These results suggest that the metal halide light source is effective in curing composite materials within a shorter period of time and with improved conversion.
