　　1低模量单组分聚氨酯密封胶: 通常所说的低模量单组分聚氨酯密封胶是按 ＩＳＯ１１６００所定义的，以１００％拉伸模量在２３℃时小 于０．４ＭＰａ或－２０℃时小于０．６ＭＰａ为低模量密封胶。在产品设计上，它与通常所说的高模量单组分聚氨酯密封胶有很大不同，在国外也只有少数公司能生产。在混凝土等多孔性材料中，水分可以通过孔隙迁移。

　　1 low modulus of single component polyurethane sealant: usually the low modulus of single component polyurethane sealant is according to the definition of ISO11600, with 100% tensile modulus of less than 0.6MPa for low modulus sealant at 23 DEG C or less than 0.4MPa from-20 deg. In product design, it is quite different from what is commonly known as high modulus one component polyurethane sealant, and only a few companies abroad can produce it. In porous materials such as concrete, moisture can migrate through pores.

　　在水分向界面迁移的过程中，碱性物质在界面聚集，后在混凝土接缝等界面处形成相对疏松的石灰质层。密封胶如果模量过高，在混凝土接缝变形过程中，密封胶容易在混凝土接缝界面上发生粘结破坏，因为界面的强度低，而密封胶本体拉伸强度高。如果密封胶本身拉伸强度很低，其在接缝扩张、密封胶被拉伸过程中，本身强度低于界面粘结强度，则不会在界面发生粘结破坏。因此，在混凝土接缝密封中，适宜采用低模量单组分聚氨酯密封胶。另外，低模量单组分聚氨酯密封胶在混凝土和其他建材如石材、矿棉板、保温、石膏板、铝板等的接缝密封上也具有良好的应用前景。韩立没有避讳的承认道。

　　In the process of migrating to the interface of water and alkaline substances in the interface together, finally the formation of calcareous layer is relatively loose in concrete joints at the interface. If the modulus of sealant is too high, in the process of concrete joint deformation, sealant is easy to bond failure on the interface of concrete, because the strength of the interface is low, and the tensile strength of the sealant body is high. If the tensile strength of the sealant itself is very low, it will not bond failure at the interface when the joint expansion and sealant are stretched, and the strength is lower than the interfacial bond strength. Therefore, the low modulus one component polyurethane sealant is suitable for the sealing of concrete joints. In addition, low modulus of single component polyurethane sealant in concrete and other building materials such as stone, mineral wool board, insulation, gypsum board, aluminum joint sealing also has a good application prospect.

　　11月22日，南安迎来了国家知识产权局专利局专利审查协作京外中心带教导师屠怡范一行人，在本次专题讲座上现场发布了《泉州水暖卫浴产业专利导航分析报告》，现场屠怡范指出当下泉州马桶**急需提升的现状，并给出了马桶**具体发展的建议。其实在今年的**调查数据中可以发现，在智能马桶方面的**还存在多方空白，而科勒在我国的相关**数量低于松下和TOTO，但无论从申请总量还是发明专利数量、有效**数量上看，其都比我国卫浴公司在该领域提交的专利申请总量还要高。表明国产马桶目前**欠缺的现状。据了解，泉州马桶领域专利申请数量明显偏少。报告称，针对上述问题，屠怡范认为，当前的工作重心仍应放在专利培育，实现水暖产业技术创新能力、**数量及质量的整体提升。**发展建议一：靠专利布局打入海外新兴市场泉州作为海上丝绸之路的起点，水暖卫浴产业的海外布局非常重要。屠怡范说，西欧、北美这几个传统卫浴消费市场，仍被欧、美、日的几大跨国企业所占据。
