                                                 氧化鋁空心球制品圖

        本制品采用純氧化鋁空心球,氧化鋁微粉為主要原料,添加適量高溫結合劑,經1750℃高溫燒成。制品具有體積密度小、熱容量小、強度高、封閉氣孔多、抗剝落和熱穩定性好等特點。用作高溫窖爐保溫材料和高溫窖爐內襯。
        Alumina Bubble Produvtis sintered at high temperature of 1750℃ and made maily feom pure Alumina Bubble,Alnmina micropowder definife high temprature cement. It has thecharacrers of low bulk density and thermal capacity,high strength, lots of invisible porosit, spalling resistance and good thermal steadiness. Lt is used as the high temperature insulaton material kikn inner liners.
