如何檢測白剛玉磨料粒度

優質白剛玉微粉的具有哪些特點？白剛玉微粉的物理性能介紹及應用

    白剛玉磨料是一種人造磨料，是行業中使用最為廣泛的一種，它的制作方法非常的復雜，采用特殊的冶煉工藝制成，白剛玉再經過粉碎整形，磁選去鐵等工藝處理，有白剛玉號砂、白剛玉段砂、白剛玉細粉、白剛玉微粉之分，篩分成多種粒度，白剛玉-拋光研磨之首，適用于各種形式的研磨加工等等，那白剛玉粒度如何檢測呢？

    主要有以下三種方法：

    1、篩分法。優點：簡單、直觀、設備造價低，常用于大于40um的樣品。缺點：結果受人為因素和篩孔變形影響較大。

    2、沉降法（包括重力沉降和李新沉降）。優點：操作漸變，儀器可以連續運行，價格低，準確性和重復性較好，測試范圍較廣。缺點：測試時間較長，操作比較繁瑣。

    3、顯微鏡（圖像）法。優點：簡單、直觀，可進行形貌分析，適合分布窄（最大和最小粒徑的比值小于10：1）的樣品。缺點：代表性差，分析分布范圍寬的樣品比較麻煩，無法分析小于1um的樣品。
