| 摘 要： | 新研制的水基锆英粉涂料包括底涂料和面涂料。底涂料具有较好的涂渗性，涂渗深度达到2．6mm，它既有填隙作用，又可减缓砂型的激热膨胀，面涂料具有较好的厚涂性，单次刷涂的干厚度达到1．1mm，具有较好的抗金属液冲刷和侵蚀特点，新开发的Z－1砂是1种粒形圆整，表面光洁的铝硅系耐火材料，具有热膨胀率小，树脂耗量低和能适度烧结的特点，生产试验表明，配合使用上述Z－1砂和新型双层涂料，能有效防止呋喃树脂砂厚大铸钢件的金属渗透。

| Abstract: | The developed water based zircon powder coatings include base coating and surface coating. The coating possesses a good permeability of 2.6 mm with a desirable filling and anti thermo expansion of sand mold. The surface coating has a thick coating character of 1.1 mm with a good anti erosion character on liquid metal. The above double coatings combined with newly developed Z 1 sand can effectively prevent metal penetration in large size steel castings by no bake furan resin sand process. |
