| 配制方法： |
In each case the concentration of "Baymal" in the water is sufficient to develop thixotropy and prevent the alpha alumina from settling.
To 194 ml. of water in a one-quart blender is added 27.5 g of "Baymal", and the mixture is stirred at high speed for one minute. then three drops of a silicone antifoam agent are added and stirring continued until a uniform, very thixotropic semi-fluid mass is obtained. Then 278 g of tabular alumina (Alcoa T-61, through 325 mesh) is added, and stirring continued until homogeneous. |
