Bamboo is a very good health household items, bamboo fiber insoles made pillows are good products. The focus of each product is different, there are some charcoal for moisture adsorption capacity has conditioned space humidity. But charcoal sparse aperture low iodine value, not as a harmful gas purification products. Its aperture to capture harmful gases is weak, unable to live capture strong adsorption of formaldehyde molecules. Activated carbon pore by pore size can be divided into three categories. Big hole: Radius 1000 - 1000000 A. Transition pore: Radius 20 - 1000 A. Microporous: Radius - 20 A. Activated carbon made from different materials having different pore sizes. From the coconut shell activated carbon has a minimum pore radius. Wood activated carbon has a maximum pore radius generally, they are used for adsorption of larger molecules, and almost exclusively in the liquid phase. Water treatment in urban areas used in the first type of granular activated carbon that is made of wood, called charcoal. Coal activated carbon pore size in between. Activated carbon in coal, lignite anthracite, activated carbon has more transition pore and larger average pore size, it can effectively remove organic molecules in water. Generally activated carbon used in water treatment, the surface area not too large, but should have a higher transition pore and a larger average pore size. Japan Market Complex liquid phase activated carbon sold some of the following characteristics: specific surface area of ??850 to 1000m2 / g, a pore volume of 0.88 to 1.5ml / g, an average pore radius of 40 to 50A. Carbon Features: Activated carbon has a high efficiency air purification, activated carbon can create a comfortable and clean environment, health care is more activated carbon, activated carbon is invisible air filters, activated carbon is a physical adsorption and chemical decomposition of combining functions, decomposition of formaldehyde in the air, ammonia, benzene, cigarette smoke and other harmful gases and odors, especially carcinogenic aromatic substances, activated carbon has a strong adsorption capacity, is a commonly used adsorbents, catalysts or catalyst carrier easily with the air of harmful gases full contact, activated carbon adsorption pore will use its harmful gas molecules inhalation hole, blow clean and fresh air. Therefore, the family partners without activated carbon.
