在大量DVD的技术难点中,粘合技术仍是争论和发展的热点。在DVD生产中粘合剂原材料的重要的作用不可忽视,选用新的DVD-9镀层材料还需顾及粘合剂的选择。在DVD发展初期粘合过程就是比较棘手的工艺之一,DVD的产品要求两个半片粘合后不容许引起变形,激光束能够透过多层薄膜到达两个信息层,DVD由于面临这些问题需要开展一系列的研究。粘合技术在不断地发展和优化,与粘合技术相应的各种粘合剂也必须不断开发出来,以满足各种DVD格式及其技术标准。单张DVD是由两张0.6mm半片粘合而成,厚度为1.2mm。DVD粘合的方法主要有热熔法和紫外固化法两
In a large number of DVD’s technical difficulties, bonding technology is still a hot debate and development. The important role of binder raw materials in DVD production can not be ignored. The choice of new DVD-9 coating materials also requires the choice of adhesives. In the early stage of DVD development, the bonding process was one of the more difficult processes. The DVD product required two halves to be bonded and not allowed to deform. The laser beam was able to reach two information layers through a multi-layer film. DVDs were faced with these problems Conduct a series of studies. Adhesive technology is continually evolving and optimized, and a wide range of adhesives are required that are continually developed to meet various DVD formats and their technical standards. A single DVD is made of two sheets of 0.6mm half-glued, a thickness of 1.2mm. DVD bonding methods are mainly hot-melt method and UV curing method two
