粘固剂层厚度对铸件就位、预防菌斑沉积等有重要作用,它受多种因素,如材料粘滞度、粒度、环境温度、湿度影响,此外还包括粘固剂与金属表面的理化反应,例如可湿性或表面活化能,但是表面理化性能尚未引起足够的重视。故作者做了以下实验。 The thickness of the cement layer plays an important role in casting in place and preventing plaque deposition. It is affected by many factors such as material viscosity, particle size, ambient temperature and humidity, as well as the physical and chemical properties of cement and metal surface Reaction, such as wettability or surface activation energy, but the surface physical and chemical properties have not attracted enough attention. So the author did the following experiment.
