Usage
In China it is mostly utilised in these fields:
1.Developing:natural concrete ligEPT combination. Like heat insulation and preservation resources ,floor,wallboard,lively addition and so on.
two. Chemical Sector: filtering medium,desiccant,catalyst,molecular sieve carrier.
three. Plastics and Padding Industry
four. Other people: pesticides carrier,ferEPTzer management agent.
In overseas countries it is mainly used in adhering to fields:
1.Developing Resources: as padding can minimize weigEPT and increase refract capability.
2.Abrasive Industry: primarily as abrasive and poXiHu (West Lake) Dis.Hu (West Lake) Dis.ng composition.
three.Daily-Use Chemical Sector: beauty materials,padding of cosmetics,toothpaste,soap and so on.
four.Petrochemical Market: as padding of rubber,asphalt,paper creating,paint and so on.
5.Warmth Insulator: pumice is the main materials, we can get mineral wool product right after substantial melt which is utilized as ceiling seem insulation.
