What is the development trend of perlite?
Perlite raw ore has become a mineral filler with certain functions by fine grinding, superfine grinding and surface chemical treatment. It can be widely used in rubber, plastics, cable, paint, ink and other industries.
In order to improve the properties of expanded perlite products, it is necessary to develop spherical non-porous expanded perlite as soon as possible. First of all, the perlite ore into the furnace should be as close as possible to the spherical shape rather than the irregular shape of the appropriate size before; second, the structure of the kiln should be improved and the strength of expanded perlite should be increased.
Perlite has been used as animal feed additive, padding material in chicken cage, filler, anti-caking and fluidity improving additive, veterinary preparation, insecticide, fertilizer, carrier of trace elements, absorbent or adsorbent, or for separating culture matrix and other purposes.
In a word, the further utilization of filter paper and filter aids, horticulture and fillers will make the perlite industry of our country leap to a new stage. China's perlite industry has a bright future.
