Time flies forward, and I have been working in the metallographic laboratory for twenty years. Every day, I earnestly anticipate and experience new births and surprises in the sound of sample grinding. Every sample bathed in milk like aluminum oxide polishing solution has extraordinary significance. The next step in sample preparation is to use alumina polishing solution for polishing. Whether it is 1 micrometer, 0.3 micrometer, or 0.05 micrometer, it is as delicate as milk, but hidden in this soft power, it can be invincible. I call this power" Calm down;.


Yes, after being stationary for a period of time, the aluminum oxide polishing solution will separate from the solvent into two layers. The fine and small particles of aluminum oxide settle to the bottom, telling us that they can exist independently, only suspended in the solvent. Before use, it is necessary to gently shake the packaging bottle to evenly distribute the alumina particles in the solvent. At this time, it is more suitable to spray onto the rotating polishing cloth, so that the surface of the sample can be finely polished until it reaches the desired shape.

    This is the personality of alumina polishing fluid&# 8217& Flash; Calm, without fancy colors or pleasant sounds, just unleashing its power in silence and stillness. Whether it's steel, ceramics, glass, or even any other material, it can be polished to the extreme in a slightly trembling rotation, wrapped in a velvet metallographic polishing cloth, to remove all damage and scratches, and restore the true nature of your organizational structure.

    What kind of power is this! In a slightly trembling rotation, they remained calm and melted into each other. Similarly, it made me realize that calmness, like this milk like soft and flowing aluminum oxide polishing liquid, is gentle and inclusive, with no gains or losses, and everything follows the laws of nature. For example, a fallen leaf fluttering in the autumn wind, when it falls into the field and turns into soil, it will surely nourish spring. Placing oneself in the present, without recalling the past that has passed, nor fantasizing about the future that has not yet arrived, only wandering in nature, enjoying and striving for the present, what a joy and beauty! No matter where you live, you can handle the unknown calmly, regardless of darkness, storms, famine, or difficulties. This is what the milky and soft alumina polishing solution taught me, but the external softness hides a more calm power.
