polyhedral hollow ball
| Brief introduction | |||||
| NAIKE Plastic polyhedral hollow ball is a kind of plastic random packing made of two hemispheres. Each hemisphere is made of many flabellate vanes. Its specific surface area is larger than any other spherical packings. It is the typical representative of plastic random packing.Plastic polyhedral hollow ball is extensively used for the packing towers in petroleum industry, chemical industry, alkalichloride industry, coal gas industry and environmental protection, etc. | |||||
