Noise is usually expressed in decibels activated wall materials prices, the noise level is 30 to 40 db is normally relatively quiet environment; over 50 db can affect sleep and rest. 70 dB interference conversation, causing distracted, inattentive. Long-term work or live in more than 90 db noise environment, will seriously affect hearing and cause digestive, cardiovascular or neurological disease cycle. MATERIALS activated porous honeycomb structure has the effect of absorbing noise. In addition to the physical adsorption of activated carbon adsorption activated carbon wall materials, and chemicals. Activated carbon adsorption depends both on the pore structure, but also depends on the chemical composition. What is not activated carbonaceous MATERIALS activated clay and diatom is, and containing small amounts of chemically bound oxygen functional groups and hydrogen started, such as carbonyl, carboxyl, phenols, lactones, quinones, ethers. MATERIALS price oxides and complexes with activated carbon on the surface of the diatom mud containing these derivatives from some of the raw materials, while some are activated by the action of the air or water vapor generated after activation. Activated carbon wall materials will be listed in the country. Bring "Wall came, eco natural house" as a new concept for consumers around the world presents a more healthy, stylish, simple, fast and environmentally friendly household space. Activated carbon price of wall materials, wall materials MINHOU activated, the wall came, ecological housing provided by cabo Leicester natural environmental technology.
