本文介绍一种用真空和空气压力的包埋方法。这种方法尽可能的减少了渗入到磷酸盐结合剂包埋料中的空气泡。三种常用的包埋方法如下: 1.用机能搅拌器搅拌包埋料以保证搅拌物的光滑和没有大的空气泡。将这些搅拌物振动,然后涂刷于蜡模上,继后再将蜡模沉 This article describes a vacuum and air pressure embedding method. This method minimizes air bubbles infiltrated into the binder of the phosphate binder. Three commonly used methods of embedding are as follows: 1. Stir the embedded material with a mechanical stirrer to ensure a smooth and free air bubble. Vibrations of these kneaded materials are then applied to the wax mold, followed by deposition of the wax mold
