Dalian coconut shell activated carbon (you know) - Sales Manager: Li Qi __FXT: _18301509601 company web site: _ Business QQ_631979131__ Material Factory of Beijing Beike green clean water quality to [the first], [] the credibility of the first principle of service to win the majority of the praise of customers. http://www.bjgkhxt.com/ykgk/ykhxt.html professional sewage treatment _ the environmental services of water _ Professional _ so professional! 
 Water Treatment Material Co., Ltd. of Beijing Beike Green cleaning with major institutions and research institutes in close cooperation with, and constantly develop new products, to accelerate the upgrading of products to meet market demand. In marketing, always follow the "science and technology as guide, quality and development" business philosophy, and sincerely listen to the opinions of the users, for users need, like users would like the tree of good corporate style, quality and credibility dominate the market, pioneering market to quality service has won the majority of users. Products has been the monitoring of water treatment media of the Ministry of Construction Quality Supervision and Monitoring Center and the National Drainage Standards Committee and other units identified, the indicators have reached the ministerial standard varieties of activated carbon, for your purchase. 

 Husk, coconut shell, there are coal activated carbon activated carbon, we are doing what? 
 Water Treatment Co., Ltd. of Beijing Beike green cleaning give you a satisfactory answer: the best quality coconut shell activated carbon, and of course the price is the highest. Family with a small package, each corner of the corner off the release are to move to the former test, you will find good results, especially in summer fast release of formaldehyde, the effect is obvious, the best move in the furniture and then activated carbon, formaldehyde in furniture ! 


 How to identify the activated carbon is good or bad? 

 1, the density of a look: activated carbon pore is more, the higher the adsorption properties of activated carbon the more crisp, the relative density is lower, the feel will be the lighter weight packaging case, the volume is greater. Proposed purchase of the density, light touch, such as weight and volume of activated carbon products. 
 2, second look at particle size: the smaller the carbon particles, the greater the area exposed to air, the greater the specific surface area, adsorption properties, the better, but the smaller the particle, the greater the loss crushed in the production process, dust is also more the higher the cost, many manufacturers to reduce costs, the use of large granular activated carbon, the performance is of course not, the general particle size of about 0.5 mm activated carbon not only achieve the best performance, but also to ensure that not a powder, and no pollution. Recommended to choose a particle diameter of activated carbon products in the range of 0.42-0.85 mm. 
 3, to see three components: the activated carbon absorption of harmful gases depend on the pore size, different harmful gases of different molecular weight, particle size, the activated carbon gap to 0.45-2 nm in order to absorb formaldehyde and other toxic gases, the international coconut The shell charcoal is the preferred activated carbon for odor absorption and stupid pollution, gas spherical microporous activated carbon is the best formaldehyde adsorbed carbon. The proposed purchase by the coconut shell activated carbon and gas spherical microporous activated carbon mixed into the adsorption products. 
 Four, four to see dust: the production of activated carbon process, you must crush the raw materials to remove dust handling, otherwise too much dust, cleanliness and sent, it will on the human body and objects pollution, low-quality activated carbon on the market to reduce costs, there is no post-processing, dust, and more dark bags, small carbon package by hand feels dirty, soiled items used to cause secondary pollution. Recommended to choose a small carbon package is a white breathable non-woven bags, feels there is no dust is not dirty. 
 5, five Enterprise: Professional activated carbon manufacturers, factory-direct products, technical quality was excellent, the cost was not cost-effective go, the market of low-quality activated carbon manufacturers, mostly trading companies, and more building materials City production of activated carbon there is no production capacity, the manufacturers of these brands, and no product standards and enterprise standards, the quality can be imagined. Recommended to choose the products of the professional production of activated carbon production. 
 Six, six to see the packaging: the packaging of the activated carbon must be sealed air will fail, otherwise contact the Director of the point of sale time, and yet would have expired. Recommended to choose a completely sealed product packaging. 
 7, the size of the package of the seven Small carbon: Activated carbon is the passive absorption of harmful gases, small carbon package to be dispersed placed near to sources of pollution, the adsorption will be more direct, more effective, the effect was better. Recommended to choose the products of small carbon package weight of 30 to 50 g / bag. 
 Eight to see bubbles: a small activated carbon into the water, the water molecules is small, the water will gradually into the pore structure of activated carbon, forcing air out of the pore, resulting in a series of very small bubbles in the water, pulled out a small the bubble line, and will issue a trace of bubbles sound, the better the performance of activated carbon this phenomenon is more severe. The proposed purchase of this phenomenon is intense and long duration of the activated carbon. 
 Nine, nine to see ingredients: the market inferior products, multi-sampling industrial cylindrical activated carbon from coal, or the particle diameter greater than 2mm of large granular fruit shell carbon or granular charcoal, these are not civilian gas adsorption activated carbon. The proposed purchase of small particles (particle diameter 0.5 mm) professional gas adsorption of coconut shell charcoal and spherical microporous activated carbon. 
 10, ten is not charcoal: charcoal only after the carbonization process, not through the activation process of carbon, is not really the activated carbon, while the activation process is the most important manufacturing process of the pore structure in activated carbon manufacturing process, the lack of this process of carbonization The material is almost no adsorption performance. Charcoal because there is no activation of the pore-forming process, so the surface than the activated carbon is smooth, and the color white, slightly metallic luster than the activated carbon hard feel, and the weight is also a lot of weight, no activation of coconut shell charcoal one kilogram. about 2.5 yuan, which is useful low activated carbon on the market posing as the motive of the activated carbon sales. Recommended to choose a real regular manufacturers of activated carbon, do not select the trading company of shoddy products.
