　　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。以防有心怀不轨的，夹带私藏了灵药。

　　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.

　　据统计，近10年来我国各类水污染事件频发，虽然净水器能够一定程度上消除一些杂质，但家用净水器对水资源却浪费严重。据了解，一杯纯净水会产生三杯尾水，因此净水器也有另外一个恶名废水器。而且，在下这种有缺陷浪费水的问题已二十余年，至今未能解决！边净化边浪费，净水器成水老虎规模超千亿，水资源浪费严重我国净水器市场处于起步发展阶段，据**预测未来市场空间将超过千亿。其中，净水设备主要分微滤、超滤和反渗透三大技术，而反渗透技术是目前主流的净水技术，虽然一定程度上可以净化污染严重及复杂的水质。不过业内人士提醒，消费者在选购反渗透净水机时，也要咨询一下废水比。尽管反渗透（RO）净水器以净化而得名，但也存在着水浪费的问题。一般的反渗透（RO）净水器废水比为1:3。形象一点儿说，就是每出1杯纯净水、就要丢掉3杯废水。以家庭为例：我们通过净水器对自来水进行饮用净化，每喝掉100升净化水，背后却隐藏的是300升水被当成废水丢掉了。
