    一.环氧地坪漆漆膜返碱的原因
        Epoxy floor paint film back to base reasons
    1.水泥基材未干透即进行施工,地坪基面含水率高,碱性大;
      cement base that is not dry for construction, floor base with high moisture content, alkaline big;
    2.地坪基面没有很好地进行涂刷抗碱封闭底漆,使基材中(例如抹灰材料中的水泥、石灰或石膏等)的可溶性盐类容易迁移到涂膜表面;
      floor base surface is not well for brushing alkali sealer so that the base material (such as cement plastering materials, lime or gypsum, etc.) easily soluble salts migrate to the surface of the coating;
    3.地坪进行批刮腻子处理时,使用的腻子耐水性差,碱性强,且腻子未干透即开始涂装地坪漆涂料;
      floor treatment for putty, putty used poor water resistance, strong alkaline, and began painting putty does not dry floor paint coatings;
    4.使用的地坪漆涂料档次低,性能差,可溶性盐类容易透过地坪漆涂膜而迁移至表面。
       floor paint coatings used low-grade, performance is poor, soluble salts easily through floor paint coating and migrate to the surface.
    二.环氧地坪漆漆膜返碱的解决办法
       Epoxy floor paint film back to base solutions
    1.待济南自流平 http://www.jndmzp.com/地坪基面干透再施工,地坪漆涂装涂料时基层条件应符合施工规范要求;
      Subject to Jinan leveling floor base surface dry and then construction, floor paint coating paint grass conditions should be consistent construction specifications;
    2.使用性能好、封闭性强的耐碱封闭型地坪漆底漆对基层进行封闭处理;
       use of good performance, closed strong alkali closed floor paint primer will be closed on primary processing;
    3.使用高性能的腻子,例如,强度高、抗渗、防裂的弹性腻子涂料等;
      Use the putty performance, such as high strength, impermeability, flexibility cracking putty paint;
