How to use activated carbon to filter liquor
Look at the components of activated carbon depends on the pore size of the adsorption of harmful gases, harmful gas molecules with different amount of different particle size are different, the activated carbon gap in 0.45-2 nm can absorb formaldehyde and other toxic gases, the coconut shell charcoal is the first choice of activated carbon adsorption odor and stupid pollution gas, spherical microporous activated carbon is the ideal carbon adsorption of formaldehyde. Recommend the purchase of coconut shell activated carbon and gas phase spherical microporous activated carbon mixed into a comprehensive adsorption products. Not necessarily coconut shell is the best, and harmful gas molecules to match the aperture.
Look at the size of the smaller carbon particles and air contact area is larger, the specific surface area is larger, the adsorption performance is better, but the smaller the particle crushing loss, the production process is more and more dust, the higher the costs, so many manufacturers to reduce costs, the use of large granular activated carbon of course, the performance is not good, active carbon in about 0.5 mm average particle size so as to achieve the best performance, and make sure it's not powder, no pollution. Recommended to choose the particle diameter between 0.42-0.85 mm of activated carbon products.
Look at the density of activated carbon pore number, the adsorption performance of activated carbon is higher, more crisp, the relative density is low, will feel lighter in weight in the case of packaging, the volume is also bigger. The proposed purchase of small density, light touch, such as the weight of large volume of activated carbon products.
Activated carbon in our life is mainly used to absorb harmful gases and substances, especially in the home decoration used more. Shijiazhuang in addition to formaldehyde fixed enterprise better than good Shijiazhuang Environmental Protection Engineering Co. Ltd. senior engineer Zhang Gong said: the market there are many brands of activated carbon, but the quality is uneven, there are a lot of ordinary carbon as active carbon. So, how to identify and select activated carbon?.
Look at the production of activated carbon dust in the process, must crush the material to remove dust, or dust too much, cleanliness is poor, it will cause pollution to the human body and the goods on the market, in order to reduce the cost of poor quality of activated carbon, no postprocessing, large dust, multi use dark bags, small hands up for carbon the use of dirty, dirty things cause two pollution. Recommend the selection of small carbon bag is a white breathable non-woven bag, feel no dust is not dirty products.
