The porous Ceramic Filtering Agents are commposed of many even-distributed and inter-blended arch-shaped pores.When the fluid passes through theses pores,the suspended substances and the glued particles and large molecule organic substances will be stopped and absorbed to the pores,which results in purification and filtering.They have the properties of high intensity,high corrosion resistance and heat resistance,collision resistance,pollutant-free,even-distribution of the pores,making longer service years and easier to be recycled,espencially applicable of filtering the gas,fluids and liquides.
