水基涂料对树脂自硬砂强度影响的研究

Study on the Effect of Water-Based Coating Material upon the Strength of the Resinn Self-Hardening Saud

给出了树脂自硬砂用新型水基涂料的特点及涂敷工艺规范，生产实践表明，采用新型水基涂料和正确的涂敷工艺规范，可强化型（芯）表面，防止铸造缺陷，获得优质铸件．

Presents the features and technology criteria of a new type water-based coating materialused in resin self-hardening sand. Experiments show that the application of the new type wat-er-based coating material and correct coating technology criteria can strengthen the surfaces of themolds and cores to prevent casting defects and obtain high quality castings。
