PVC封边条的制备及其光泽度衰减趋势研究

Preparation of PVC Edge Sealing Bar and Study on Its Glossiness Attenuation Trend

介绍了板式家具常用封边条分类,阐述了哑光、平光和高亮光封边条分类以及封边条的主要功能,并对PVC封边条从混料、挤出造粒、挤出成型和印刷整个生产加工过程做了说明。对光泽度仪和光泽度测试原理做了论述,根据光泽度仪测试方法,跟踪测试封边条光泽度变化,分析探讨哑光、平光和高亮光封边条光泽度衰减变化趋势,分析了衰减原因。结果表明:哑光、平光最大衰减度为3 Gs,高亮光光泽度衰减无明显趋势。

The classification of common edge-sealing strips for panel furniture was introduced,the main functions of matt,flat and high-brightness edge-sealing strips were expounded,and the production process of PVC edge-sealing strips was explained,including mixing,extrusion granulation,extrusion moulding and printing.The glossiness tester and the principle of glossiness measurement were discussed in detail.According to the use method of glossimeter,the glossiness changes were tracked and tested.The glossiness decay trends of sub-gloss,flat gloss and high gloss seals were analyzed,and the reasons for the decay were discussed.The results showed that the greatest glossiness attenuation of sub-gloss and flat-gloss seals was 3 Gs,while that of high-gloss seals had no obvious trend of glossiness attenuation.
