Activated alumina spheres are porous and highly dispersed spherical adsorbents. Activated alumina spheres are widely used as catalysts and catalyst carriers for chemical reactions because of their large specific surface area and their microporous surfaces have the characteristics required for catalysis, such as adsorption performance, surface activity, excellent thermal stability, etc. High-performance activated alumina can bring the following benefits in the batch of unshaped refractory materials: increasing the density, fluidity and strength of the blank, increasing the amount of secondary mullite formation, etc., and reducing the amount of water added and porosity. In addition, activated alumina can also be used as desiccant, with large water absorption, fast drying speed and regeneration (baking at 400 -500K).
1.Chlorine can be used on swimming.pool and drinking water treatment ,clean the industrial circulating water. 2.Chlorine can sterilize tableware,and be used as preventive disinfection of house,hotel,hospital public place. 3.Chlorine can be used on the environmental sterilization of raising fish ,silkworm,livestock,poultry,and so on. 4.Chlorine can be used to bleach the textile,to prevent wool from shrinkage ,to stop eating paper by moth,and act as rubber chlorination.
Disinfection with Chlorine | Public Water Systems | Drinking
Chlorination is the process of adding chlorine to drinking water to disinfect it and kill germs. Different processes can be used to achieve safe levels of chlorine in drinking water. Chlorine is available as compressed elemental gas, sodium hypochlorite solution (NaOCl) or solid calcium hypochlorite (Ca(OCl)2 1
