Environmental Science and Technology Co., Ltd. Fuzhou cabo Leicester (www.cblst.com) is located in Jinshan Industrial Zone, Fuzhou, Fujian, 34, Contact: Ms. Chen is the first issue of activated carbon masks, in the 1920s in the first World War applications. Activated carbon can be sub-divided into application history as the first phase and the second phase boundaries. The main application is in the early stages of activated carbon powder, carbon in the sugar gradually replaced the original bone char. Particles appearing in the 1920s, widely used in the First World War gas masks. This is a glorious page in the history of industrial chemicals. At that time the Dutch Norit and manufacturers and wholesalers Czechoslovakia, Germany, France, Switzerland and other countries have set up a joint company, described in the European bud activated carbon also been widely promising new industries. By promoting the use of gas masks, entered the second phase of the history of activated carbon air purification Masters MATERIALS activated, activated carbon market continues to expand, activated carbon adsorption and catalytic function in many industries refining, recycling, on the application of synthetic continue to develop, the United States and other activated carbon plant opened in succession. In the middle of the 20th century, expanding the application of activated carbon surface, are considered "universal sorbent." Although the use of activated carbon in terms of shape and can have many varieties, but there is a common characteristic of the activated carbon, that is, "adsorbent." Activated carbon adsorption generated reason is because it has a well-developed pore structure, as we have seen activated carbon sponge product innovation wall materials, activated carbon China green building materials wall materials, sponge than the weight of other objects in the same conditions can absorb more water, the reason is because it has a well-developed pore structure. But this is the pore structure of activated carbon charcoal wall materials naked eye can not see, because they only have between 1 × 10-12mm-10-5mm, much better than a big deal molecule. The degree of pore development of activated carbon is difficult to imagine that if taking one gram of activated carbon, the inside walls of the hole are all expanded into a plane, the area will reach 1000 m2 (both specific surface area of ??1000m2 / g)!
