The porous ceramics is composed of lots of bridge arch - shaped microspores that connected and well - distributed inside the material . when the fluid passes through these pores , the suspended matters , colloid particles and big molecular organic substances are withheld or absorbed to the inner surface of the pore , and result in filtration , purification adn even - dispersion , high strength , good resistance to abrasion , high temperature and corrosion , no pollution , long workinglife , and easy to regenerate , the porous ceramics are available for filtration and fluidization of variou gas and liquid 微孔陶瓷過濾介質由許多大小分布均勻,相互連通的橋拱狀開口氣孔組成.當流體從這些氣孔中通過時,流體中的懸浮物質,膠體顆粒,大分子有機物等被截留,吸附在微孔道內,從而達到了凈化和過濾均勻化的效果.微孔陶瓷強度高,耐磨損,耐高溫,耐腐蝕,無污染,氣孔分布均勻,使用壽命長且再生簡便,特別適用于各種氣,液過濾和流態化過程
