Biqing offer free samples, technical support, Tracking service, your satisfaction, my pleasure ......... efficient coconut shell activated carbon adsorbent can fully remove formaldehyde, benzene, TVOC and other harmful gases, but also you fresh, healthy space. Tips: (1) look at the packaging: professional home with activated carbon can be divided into many small carbon package, directly on the cupboard, drawer can be, we all know that charcoal will fail if exposed to air, so regular charcoal outside packaging, must be sealed, if it is packed in plastic bags, must be sealed, and can not be loaded with the kind of bread that ziplock or glued together by a sealed package, because these are not sealed package, a long time you fail do not know, the effect of course is not good. If the carton packaging, it must then have a carton outer shrink film for the job, and some manufacturers directly with carton packaging, which use a ziplock bag, seal or bad results. (2) look at the size of the bag of coconut shell activated carbon: Activated carbon is passive absorption of harmful gases, so the larger the contact surface and the air, the more uniform the better placed in the actual application process are generally made of 30g-50g / bag small, those who can not disperse hundreds of grams of placing small bag packing their less effective. (3) See coconut shell activated carbon particle size: the particles are not more than 1.5mm: national standards specified inside the activated carbon particles to be in the 20-40 mesh, particle conversion came about is 0.42 ~ 0.85mm, 1.5mm above those granular activated carbon in the the effect is no small particles of activated carbon with good effects. In general, the smaller the particles of activated carbon, the greater the surface area, which is adsorbed better, but the smaller the particle, the loss will be greater, the dust will be greater, so many manufacturers to reduce costs, the use of large particles activated carbon, the effect will be greatly reduced. (4) coconut shell activated carbon sales currently on the market many brands of charcoal; charcoal is simply baked, and coconut shell charcoal is made after deoxygenation and activation, so charcoal adsorption effect will be greatly reduced. Here are a few tips for you: a, charcoal cross-section of a shiny, smooth surface with no cracks, wrinkles or holes. b, quality bamboo structure is very dense and therefore less likely to break or fall when the beat and difficult to break. c, will issue a sonorous ringing metallic sound when the beat, rather than blunt tone pound. d, high-quality charcoal can be conductive, available multimeter to measure the conductivity of charcoal whether a coconut shell activated carbon, coconut shell activated charcoal category belong, its main feature is the density of small, light touch in his hand weight significantly higher than coal Light activated carbon. The same weight of activated carbon, coconut shell activated carbon is generally greater than the volume of activated carbon from coal. 2, the general shape of the broken coconut shell activated carbon granules, flakes, and molding carbon, such as cylindrical, spherical activated carbon, mostly from coal char. 3, because of the small coconut shell activated carbon density, feel light, so if you put the water activated carbon, coal carbon sink to the bottom faster in general, and coconut shell activated carbon floating in the water for longer time, with coconut shell activated carbon adsorption of water molecules saturated, increasing their weight will gradually sink to the bottom of all, when the charcoal all sink to the bottom, you'll see every single charcoal outside wrapped with a small bubble, crystal Ti thoroughly, very interesting. 4, coconut shell activated carbon pore structure of small molecules, activated carbon into the water, when it absorbed water molecules will produce many rows of very small air bubble (just the naked eye can see), dense kept floating to the surface. The bubble phase activated carbon from coal is generally macromolecular pore structure, also produced larger. Coconut shell activated carbon is high-quality coconut shell as raw materials, production process from finishing the series. Appearance is black, granular, with a gap developed good adsorption properties, high strength, easy regeneration, economic and durable and so on.
