避免环氧地坪形成缩孔，该怎么解决
1.增加湿地坪漆漆膜厚度1. Increasing the Thickness of Wetland Lacquer Film 湿地坪漆的漆膜容易被表面张力低的尘粒污染，如果地坪漆的漆膜够厚，就不会有明显的缩孔形成；如果地坪漆漆膜较薄，底部没有地坪漆涂料补充就会形成缩孔。 Wetland floor paint film is easy to be polluted by dust particles with low surface tension. If the film is thick enough, there will be no obvious shrinkage. If the film is thin, there will be shrinkage at the bottom without the supplement of floor paint. 2.增大湿漆膜的黏度 2. Increasing the Viscosity of Wet Paint Film 如果湿地坪漆漆膜的黏度增加到能够阻止涂料的流动时，即使涂料有缩孔的可能，也不会产生缩孔，所以添加触变剂能提高湿漆膜的黏度，也能防止缩孔。 If the viscosity of wetland floor paint film increases to prevent the flow of paint, even if the paint has the possibility of shrinkage, it will not produce shrinkage, so adding thixotropic agent can improve the viscosity of wet paint film, but also prevent shrinkage. 3.表面张力低的地坪漆涂料不容易形成缩孔 3. Low surface tension floor paint is not easy to form shrinkage 因为比这种涂料表面张力更低的杂物较少。醇酸涂料的表面张力很低。聚醋涂料比丙烯酸类涂料的表面张力高，缩孔问题比较多。 Because there are fewer impurities with lower surface tension than this kind of paint. The surface tension of alkyd coatings is very low. Polyvinegar coatings have higher surface tension and more shrinkage problems than acrylic coatings. 4.地坪漆涂料的配方要合理 4. The formulation of floor paint should be reasonable. 不能出现地坪漆涂料中各个组分之间相互溶解性能不好，干燥过程中因溶剂挥发造成某些树脂溶解性不良而析出的现象。 It can't occur that the solubility of each component in the floor paint is not good, and the solvent volatilization during drying causes the precipitation of some resin which is not good in solubility |
