　　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。看来一些人说的没错，这毒虫类妖兽果然极为的难缠。

　　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.

　　壁纸有别于其他室内装饰材料，其日常使用和保养非常方便，可洗可擦，没有其它的特殊要求。房天下透露，精心保养是延长壁纸寿命的关键，保养又包括了铺贴前、后期的保养。施工前：检查平整度铺贴壁纸应选择空气相对湿度在85%以下，温度也不应有剧烈变化，一定要避免在潮湿季节和在潮湿墙面上施工。

要想壁纸铺得美观耐用、不易起泡翘曲，施工前墙面的处理十分重要。准备贴壁纸的墙面须平整干燥、无污垢浮尘在铺装壁纸之前，我们建议在墙上先涂一层聚酯油漆以便防潮防霉。施工时：保持高度清洁粘贴壁纸时会溢出胶粘剂液，应随时用干净的毛巾擦干净，尤其是接缝处的胶痕要处理干净。

要求施工人员将手和工具保持高度的清洁，如沾有污迹，应及时用肥皂水或清洁剂清洗干净。施工后：保持通风铺贴后，白天应打开门窗，保持通风晚上要关闭门窗，防止潮气进入，同时也防止刚贴上墙面的壁纸被风吹得松动，从而影响粘贴的牢固程度。施工后：定期清洁还要定期对墙纸、壁布进行吸尘清洁，注意要将吸尘器换吸头。

日常发现特殊脏迹要及时擦除，对耐水壁纸可用水擦洗，洗后用干毛巾吸干即可对于不耐水壁纸则要用橡皮等擦拭，或用毛巾蘸些清洁液拧干后轻擦。此外，还要去正规的建材市场或者房天下装修公司购买壁纸，切勿去小商小贩手中购买，以免上当受骗。平时要注意防止硬物撞击、摩擦墙纸和壁布。倘若有的地方接缝开裂，要及时予以补贴，不能任其发展。
