　　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。要知道，只有筑基期以上的修士，才会神识充足，可支撑起分神地痛苦。

　　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.

　　春节过后，多建陶产区厂家发出瓷砖涨价通知，其中泛高安和夹江两产区抛光砖涨幅为明显，甚至有陶企声称出现了产品供不应求、库存告急的火爆场面。以800 ×800mm规格抛光砖为例，节后多产区抛光砖销售旺盛，图为排队等待拉货的车队。江西泛高安产区同样因为产能减少和生产成本的提升，让前两年一度滞销的抛光砖华丽转身变成了脱销的产品。的消息显示，继开年后轮涨价后，3月该产区又有一部分厂家再次发出涨价通知。高安产区继开春开启首轮涨价后，部分企业3月再度涨价。回顾2016年泛高安产区的抛光砖价格，却是一路滑落，800倍800mm规格的普通抛光砖价格曾跌落至12元片以下而目前，该类产品的价格已经开始回涨，对于抛光砖价格再度上涨的原因，业内人士分析到：尽管抛釉砖已成为市场的主流，但市场对抛光砖仍有需求，但近两年抛光砖生产线急剧减少后，产品开始趋于供求平衡。随着环保整治要求严苛，厂家长时间停产限产导致供应不足，价格也就随之上涨。
