維卡軟化點測試的簡單介紹

維卡軟化點測試的詳細信息

安裝與操作說明：

試驗前的準備工作。 根據試驗類型選擇試驗壓頭，熱變形為圓角壓頭，維卡為針型壓頭。將所需的壓頭與負載桿固定好。 根據試驗類型和試樣的尺寸計算載荷： a、熱變形試驗：根據試樣的尺寸，選取載荷b、維卡試驗：只有兩種規定的負荷A法9.81N 即1000g B法 49.05N即5000g 砝碼的選配見（9）砝碼質量表 打開攪拌電機電源，指示燈亮，攪拌電機工作，攪拌速度可以通過攪拌電機控制盒上的旋鈕調節（溫度高時用慢速，溫度低時用快速），按照以上指定的程序檢查電氣，無誤后繼續做下面的工作。維卡軟化點測試 安裝試樣 將試樣架抬（升）出油面，將熱變形試樣放在支撐架上（維卡試樣放在平面上），放下負載桿，將試樣壓緊。 將試樣架放（降）回油池內，將相應質量的砝碼放在托盤上。要求砝碼放正。 將千分表固定在砝碼上方，使千分表內芯懸于砝碼之上，內芯上端有2-5mm的空間。 升溫速率設定：共有兩檔升溫速率，120℃/h，50℃/h。 每次試驗時需要對千分表進行調零，方可進行試驗，調零時輕輕旋動旋鈕，使千分表置于零區，預置3-5分鐘。 啟動工作：當一切準備工作就緒后，試驗開始。 試驗結束，記錄下溫度；移開千分表及砝碼，抬（升）起試驗架，取下試樣。注意不要把試樣誤入油池。 降溫采用氣冷或水冷，也可自然冷卻。維卡軟化點測試冷卻時，可抬起或將試樣架潛入油池。 關閉主機電源、攪拌電機電源。
