Use
In China it is mostly used in these fields:
one.Building:all-natural concrete ligEPT aggregate. Like warmth insulation and preservation resources ,flooring,wallboard,energetic addition and so on.
two. Chemical Market: filtering medium,desiccant,catalyst,molecular sieve carrier.
3. Plastics and Padding Industry
four. Other people: pesticides carrier,ferEPTzer management agent.
In foreign international locations it is primarily utilised in pursuing fields:
one.Creating Resources: as padding can reduce weigEPT and enhance refract ability.
two.Abrasive Market: largely as abrasive and poXiHu (West Lake) Dis.Hu (West Lake) Dis.ng composition.
three.Everyday-Use Chemical Market: splendor supplies,padding of cosmetics,toothpaste,soap and so on.
four.Petrochemical Sector: as padding of rubber,asphalt,paper creating,paint and so on.
five.Heat Insulator: pumice is the primary substance, we can get mineral wool item after large soften which is utilized as ceiling seem insulation.
