Cutting-edge Environmental Technology for Manufacturing Processes 竹内文代 野口道子 尾崎光男 木村浩一 あらまし VOC VOC ICT ICT 80VOC2- DEHP RoHS FT-IR 11 wt Abstract Manufacturing capabilities (monozukuri ) today cannot be considered without environmental awareness. Fujitsu Laboratories Ltd. engages in developing innovative environmental technology used for manufacturing processes. To conserve the global environment, the use of volatile organic compounds (VOC), usually contained in paints, is expected to be reduced. Application of water-based paint with no VOC content on information and communications technology (ICT) equipment has been technically challenging so far. This is because it requires high drying temperature which plastics cannot stand, while the paint must achieve high coating performance. Addressing this challenge, we have developed a coating emulsion in a core shell structure to satisfy both low drying temperature and coating performance. As a result, we succeeded in reducing the VOC content by approximately 80%. Bis (2-ethylhexyl) phthalate (DEHP), another potentially toxic substance, is being regulated in Japan, the US and the EU; and is now being considered as a candidate for next-round regulation under the EU s Restriction of Hazardous Substances Directive. Identification of the presence of a phthalate has been an issue in a factory s acceptance testing operations since simple detection methods available today are influenced by other additives in test samples, and are not sensitive enough to meet regulatory requirements. We have developed a vapor collection method, a simple pre-processing method. With this method, it is possible to detect phthalate esters using FT-IR with a sensitivity to identify less than 1 wt% contained in pre-processed samples. This is a tenfold improvement in sensitivity over the existing method, and the method is implementable in acceptance testing operations. 54 FUJITSU. 65, 2, p. 54-59 03, 2014
