中文摘要 | 鑄模表面塗層的主要功能是用以隔離金屬液與鑄模,避免兩者在高溫下發生化學或物理反應,並且提升鑄件的表面品質。塗模層的性能是否適用的重要因素包含:厚度、附著性、均勻性、透氣性、熱傳導性和高溫性質等。塗模層的性能與選用的塗模劑材料組成有密切關連。採用自硬性砂模澆鑄鑄件時,其鑄模表面往往需要使用塗模層。由於評估自硬性砂模透氣性與塗模層透氣性的方法有所不同,本研究將分析透氣性量測的相關理論、公式與方法,利用自行建立的設備研究全模鑄造法時塗層的透氣行為,而用傳統砂模透氣性的方法研究自硬性砂模的透氣性,並將討論兩者之間的關連性。 |
英文摘要 | The surface coating layer applied on the casting mold serves as to separate the metal liquid from sand mold, to prevent the chemical or physical reactions in high temperature situation. Performance of surface coating layer dependents on several factors: thickness, adhesive, uniformity, permeability, heat conductivity and high temperature properties. These factors of coating layer is closely relate to the composition of coating materials. When a resin bonded sand mold is used for casting, coating is necessary to be applied on mold surface to increase the quality of casting. But the evaluation methods for resin bonded mold and coating layer are somehow different. In this paper, the theories and equations for measuring permeability have been reviewed, and then a self constructed equipment was used to measure the permeability of surface coatings for full mold casting, and the traditional method was used to measure the permeability of resin bonded sand mold. The permeability measured by these two methods will be discussed. |
