China Indoor Environment Test Center recently survey: every year caused by formaldehyde and other harmful indoor air pollution deaths of as many as 11 million people in the country 40,000 leukemia patients every year, 50% of children aged 2-7, and indoor air pollution It is considered to be the main cause of childhood leukemia. Industry experts believe that to solve the problem of indoor air pollution has become essential, and the use of high quality activated carbon with high adsorption capacity of the product as well as reduce the impact of the elimination of formaldehyde and other harmful gases are becoming the first choice of more and more residents.

   What is the real charcoal?

   Activated carbon black particles prototype components, the volume is small, but has a large surface area, plus covered with small holes - capillary, the capillary strong adsorption capacity for gas (impurity) has thus purify the air effect, which is the basis of the principle of charcoal can effectively adsorb formaldehyde and other harmful gases.

   But all is not activated carbon can be truly effective in improving the home environment. China Forestry Industry Association branch of public documents show charcoal, activated carbon adsorption of carbon tetrachloride adsorption index reached 60%, iodine adsorption reaches belong to the activated carbon finished when 822mg / g. Only activated carbon products in line with these indicators it could really help eliminate harmful gases, and a lot of three products on the market are often under the banner name of activated charcoal, but really just selling the raw coke, and can not really work. Association called, the majority of consumers in the choice of activated carbon products must be careful, try to choose a certain brand influence and quality certification, complete testing methods of products.

   Hypobaric high quality activated carbon iodine value is true

   According to the survey, the market in the sale of a number of activated carbon products, the quality is good and bad, on including Taobao, including electronic business platform, and even some unscrupulous businessmen posing as the raw coke charcoal to sell, deceive consumers, harm the people. In fact, the raw coke is not really activated carbon, carbon materials such no activity, strictly speaking, is activated carbon semi-finished products: 1 ton to 5 tons of activated carbon raw coke to be produced, the raw coke because there is no high-temperature activation before, so the specific gravity (about In 0.7-0.85ml / g), iodine value is low (about 100-400ml / g).

   Foxwoods is the home of activated carbon industry leading brand, is also China's production of high quality activated carbon model. Their brand executives believe that quality activated carbon to improve the home environment in the production and manufacturing processes tend to have higher than normal activated carbon, more stringent requirements, only those hypobaric high iodine value of activated carbon to be able to in a modern home environment Pesticides play an effective role of the real product. To Foxwoods for example, the finished activated carbon tetrachloride (CTC) adsorption value of 100-120%, iodine adsorption 1000-1500mg / g, methylene blue 10-16ml, activated carbon is a typical high-end products. The reach of this index is based on their own strength and strong production technology reached. According to reports, Foxwoods household activated carbon production technology is based on national patents special spherical activated carbon as the carrier, using high-tech means, press A + B bicompositional scientific formula developed parts. At the same time according to the ASTM standard, JIS, GBT our strict standards for product measurement, monitoring, scientific management, the use of wood activated carbon granules unique patented formula and chemical oxidation and physical activation of combining innovative technology produced. This makes Foxwoods activated carbon pore developed, strong absorption and high activity - in terms of the elimination of formaldehyde and other harmful gases, stronger than ordinary carbon products 5-10 times, the effective absorption of up to 10 months to completely remove the home, office , hotels, public places, inside a car benzene, toluene, formaldehyde, TVOC, ammonia and other toxic gases, to really air purification purposes, is internationally recognized drug "expert."

Industry experts say, ordinary activated carbon, although with certain physical adsorption capacity, but the organization of these adsorbed substances have not been effective due to decomposition, still fully or partially to retain the original shape after a period of time will be released into the air, It makes its clean air restrictions. After quality activated carbon often through advanced technological means and formula processing, such as adding the activated carbon catalyst, to proactively capture and adsorption of harmful gases in the air, with the help of a catalyst to be firmly locked after then by chemical oxidation and physical activation There was a break down the harmful gases into harmless components, and ultimately the real purpose of purifying the air. "Normal or Activated carbon is a possible failure of the switch box, harmful gases stay in the box for some time ran out and the quality of activated carbon is the switch, harmful gases out into the fresh air - these products is the consumer most in need of real activated carbon products can purify the air. "

   Ordinary consumers how to identify and select activated charcoal?

   For ordinary consumers to identify genuine merits of the activated carbon is actually not difficult. According to reports, one of the easiest way to determine the true and false is activated carbon with blisters. Authentic carbon particles into the slurry water will not, no matter how immersed particles still exists; and water particles gone into activated carbon slurry is false activated carbon. Experts said the fake charcoal do not buy, because at home over time, absorb moisture from the air into water immediately, everywhere flow, pollution, not to mention the addition of formaldehyde.

   Experts further suggested that judge the merits of activated carbon can proceed from the following aspects:

   First, determine from the appearance of the naked eye. Typically the smaller the particles of activated carbon, the greater the surface area, good adsorption effect. For the same weight of two packets of activated carbon, a large volume of relatively better quality charcoal. Because of the large volume of instructions developed internal porosity of activated carbon, hollow channels, therefore the strong adsorption. In addition, the general effect of activated charcoal purification of poor single formulation. West is currently the practice of the single market 99% of the domestic activated carbon (using the physical production of coconut shell charcoal referred to a single recipe), this type of activated carbon is alkaline PH value, can only deal with acidic gases, alkaline gases for other powerless .

   Second, judging from the testing means. For example, an iodine value measured for the liquid phase activated carbon; activated carbon for measuring carbon tetrachloride vapor (referred to CTC, also known as gas adsorption value) or measured strength. The higher value indicates CTC eliminate harmful gas effect is relatively good, the strength of generally less than 80%, preferably 70% - described high strength low carbon solid pore volume, adsorption sent. Another method is to measure PH value. If PH> 7, or even 9 - 10 words, so an alkaline activated carbon charcoal against harmful alkaline gas is not ideal, such as toxic gas odor odor.

   Third, judging from the production of means of detection equipment. For example, manufacturers of comprehensive strength and brand influence. Some of activated carbon companies registered assets of only 100 million yuan, the scale of investment of less than 3 million, so that enterprises can not equipped with advanced activation furnace, product quality naturally can not be guaranteed. Moreover, even the production equipment and testing instruments are not, by the hands of packaging, activated carbon trading business, how to control the quality.
