Application
In China it is mainly used in these fields:
1.Building:natural concrete light aggregate. Like heat insulation and preservation materials ,floor,wallboard,active addition and so on. 2. Chemical Industry: filtering medium,desiccant,catalyst,molecular sieve carrier. 3. Plastics and Padding Industry 4. Others: pesticides carrier,fertilizer control agent. In foreign countries it is mainly used in following fields: 1.Building Materials: as padding can reduce weight and increase refract ability. 2.Abrasive Industry: mainly as abrasive and polishing composition. 3.Daily-Use Chemical Industry: beauty materials,padding of cosmetics,toothpaste,soap and so on. 4.Petrochemical Industry: as padding of rubber,asphalt,paper making,paint and so on. 5.Heat Insulator: pumice is the main material, we can get mineral wool product after high melt which is used as ceiling sound insulation.Detailed Photos
