How to choose a selection method of activated carbon charcoal hand Weigh Weight: To improve the adsorption properties of activated carbon, only as much as possible in the manufacture of activated carbon pore structure, the more porous, charcoal www.hee-carbon.com/ more crisp, the relative density also will be more light, so it would be more on a good charcoal lighter feel, in the case of the same weight packaging, good performance of activated carbon will be larger than the volume of a lot of low-quality charcoal. Iodine value: iodine number is a performance difference between the number of activated carbon, shell, charcoal, coal iodine value of all the hundreds, iodine value of activated carbon material from 800,850,900,950,1000,1100mg / g variety, adsorption capacity is different! cost price is different! with an iodine value of coconut shell charcoal and only the best. Look Bubble: A small active carbon into the water, because the water of osmosis, the water will gradually immersed activated carbon pore structure, forcing the air out of the pores, resulting in a series of very small bubbles in the water pulled out a small bubble line, and it will emit the slightest sound of bubbles, very interesting. This phenomenon occurs the more intense the longer the duration, activated carbon adsorption, the better. Look bleaching ability: Another performance of activated carbon adsorption capacity is decolorization, activated carbon can become light colored or colorless liquid magical ability, which is actually the reason is because the activated carbon adsorption colored liquid in the pigment molecules caused. Because of this feature activated carbon is widely used in the sugar industry in the field of brown sugar production process becomes. Take two transparent glass, in a cup of water into pure, then dropped a drop of red ink (where you can use any kind of easy to observe, but do not change the properties of water pigment can be, for example, blue ink, color ink printers, but you can not use the ink and the carbon ink), stir after half colored water poured another cup reserved control sample. The water samples were compared with the comparative activated carbon into the colored water, and the number should reach half of water or more, this effect will be more obvious, to stand for 10-20 minutes under the same conditions, the stronger the effect described bleaching activated carbon adsorption the better. http://www.hee-carbon.com/news/68.html
