    • An apparatus is presented for the rapid curing of resinous materials by application of energy from an external source to excite polymerization in a polymerizable system under controlled temperature and pressure. The apparatus comprises a chamber and at least one inert gas flash lamp light source arranged at a predetermined distance from the chamber to irradiate an object positioned on the sample holder. Preferably, the inert gas light source is at least one inert gas linear flash lamp positioned to effectively irradiate an object positioned in the chamber. In accordance with the present invention, the inert gas flash lamp emits pulse radiation of very high energy and power peaks. Preferably, the spectral output of the inert gas flash lamp is in the range between about 350 nm and about 550 nm. The radiant energy emitted by the present apparatus is diffused or flooded to produce an even distribution of light intensity over the entire base of a chamber. The apparatus of the present invention achieves very fast cure rates, high degrees of cure, greater depths of penetration, low heat buildup and instant on-off capability and is particularly suitable for the curing of dental materials comprising filled or unfilled resin(s) having at least one ethylenically unsaturated group, in particular acrylate, methacrylate or vinyl groups.
    • 提出了一种用于通过施加来自外部源的能量在可控温度和压力下在可聚合系统中激发聚合来快速固化树脂材料的装置。 该装置包括一个室和至少一个惰性气体闪光灯光源,该惰性气体闪光灯光源布置在离室的预定距离处以照射位于样品架上的物体。 优选地,惰性气体光源是至少一个惰性气体线性闪光灯,其被定位成有效照射位于腔室中的物体。 根据本发明,惰性气体闪光灯发射具有非常高能量和功率峰值的脉冲辐射。 优选地,惰性气体闪光灯的光谱输出在约350nm和约550nm之间的范围内。 由本装置发射的辐射能量被扩散或淹没以在室的整个基底上产生均匀的光强分布。 本发明的装置实现了非常快的固化速率,高固化度,更大的渗透深度,低的热积聚和瞬时开启能力,并且特别适用于包含填充或未填充的树脂的牙科材料的固化,所述填充或未填充的树脂具有 至少一个烯键式不饱和基团,特别是丙烯酸酯,甲基丙烯酸酯或乙烯基。
