　　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。韩立非常随意的开口问道。

　　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.

　　资金对木门企业而言，无疑是企业运行的血脉，没有血液流畅，木门企业如濒死的植物，奄奄一息。如履薄冰。资金对木门企业的重要性不言而喻。资金不足，所以才坚持。资金是个难题，很多木门企业就是资金流的阴影下，艰难生存资金是企业发展关键，但不是决定企业成败的主因。一、小木门企业的活着从供给侧**之声传出以后，不少企业都在说供给侧**，大木门企业说供给侧**，说得好听是响应国家号召，不好听就是因为穷，大木门企业尚且如此，小木门企业能怎么办？
