開孔瓷球是在惰性瓷球基礎上開發的新產品，它以球體直徑為軸心進行開孔，既具有惰性瓷球的高機械強度、化學穩定性和熱穩定性，又增加了比表面積和空隙率，從而增加了物料的分散性和通量，降低了系統的阻力。該產品自投放市場以來，已廣泛應用于石油、化工和天然氣等行業，替代惰性瓷球作催化劑的支撐覆蓋填料，深受用戶好評。

Openings in the intert balls balls based on the development of new products,it is the axis of the hole diameter sphere,both inter balls with high mechanical strength,chemical stability and thermal stabilitiy,increased more than surface area and porosity,which inceases the dispersion of the materrial and flux,reducing the system's resistance.The product on the market since,has been widely used in petroleum,petrochemical and natural gas industries,alternative inter ceramic balls for catalyst sipport covered packing,praised by users.
