活性α氧化鋁微粉在不定型耐火澆注料的性能

 

    以剛玉質澆注料為主題,白剛玉或者是致密剛玉為主要原料,實驗觀察了活性α氧化鋁微粉超级彩票助手對不定型耐火澆注料的施工性能(振動流動度)、強度及抗渣性能的影響。實驗的數據表明:在澆注料中添加適量的活性α氧化鋁微粉能提高不定型耐火澆注料在高、中、低溫下處理后的強度、并且能夠有效地提高澆注料的抗渣性能。但活性α氧化鋁微粉對澆注料的施工性能不利,且施工溫度越高,其影響越顯著。

    在干燥后的抗渣試樣中加入70g爐渣,于1600℃3h條件下進行抗渣試驗,冷卻后用切割機沿坩堝軸線將其切開,分析坩堝試樣侵蝕和滲透的程度,并進行巖相分析。可以看出,在施工環境溫度較高的環境下,活性氧化鋁加入量對浸漬管澆注料施工性能的影響比較顯著,活性氧化鋁微粉加入量對澆注料施工性能的影響比較顯著,活性α氧化鋁微粉加入量越多,澆注料的振動流動值越小,當活性氧化鋁超级彩票助手微粉的加入量超過一定量后,澆注料的流動性能將會全部喪失,而在較低環境溫度下施工時,活性氧化鋁微粉加入量對澆注料振動值流動值影響較小,并且有波折。

    這是因為α氧化鋁微粉超级彩票助手活性大,比表面積高,與水接觸是生生如下反應。此反應的速度隨著溫度的提高而加快,當在澆注料中加入含Na+的減水劑后,Na+被泥漿蠱的Al3+交換,使泥漿中的電位下降,粘度提高,從而使澆注料的流動性能相應下降。
