This glue is made of PVC in Japan, and the effect is not very good, because it blocks the pores of activated carbon; The kind of rubber we use at present seems to be a technical secret!
Since they say that "glue" can be converted into "activated carbon" after high temperature treatment, according to my chemical experience, I think it may be made of soybean protein, natto resin and so on. (or simply ordinary starch glue, in order to create a certain mystery, deliberately add the word "special", so that foreigners who are proficient in synthesis get into a dead end). Firstly, carbon particles are bonded, and then sent to a muffle furnace for anaerobic heating to about 700 degrees.
If you want to develop, I suggest you use starch glue. I trust my perception. The more mysterious things are, the cheaper they are. It's worthless to understand. Give it a try! I have two inventions, so I will never be superstitious about the advertisements discussed below. What are "uniqueness" and "N patents"? To put it bluntly, that's it. No big deal. Even if I dig deeper, the products I make are better than the performance.

"Black diamond and black carbon" is a newly listed indoor air pollution control product. It is said that this product not only has a good control effect on harmful gases such as formaldehyde and benzene commonly found in indoor decoration, but also has a good control effect on other indoor odors.
Black diamond and black carbon were developed by a company in Changsha. Its investor is a graduate of Guangzhou Academy of Fine Arts, and its inventor is a physics professor. Regarding 1992, the inventors of black diamond and black carbon accidentally learned that indoor air pollution is serious, and experts gave three solutions, one is ventilation, the other is activated carbon, and the third is molecular sieve.
Due to the limitation of technology, activated carbon has always appeared in powder or granular form, and the formed activated carbon has many impurities and low adsorption value. After years of research, the inventor of "black diamond and black carbon" finally solved this worldwide problem. According to the test results of relevant testing departments, the removal rates of benzene and formaldehyde in charcoal carving crafts made of "active solar charcoal" were 76.2% and 66. 1% respectively within 6 hours, and they were recommended as' indoor environmental pollution control products'. "
Activated carbon is internationally recognized as the best material for adsorbing pollutants. Activated carbon itself also has some unsolved mysteries, such as why it absorbs gases harmful to human body but not gases beneficial to human body? Many people know the uses of activated carbon, such as gas masks, but these things are powder or granular, and they can't be used after a while. The formed activated carbon retains the high adsorption value of powder or particles, as well as its long-term and reproducibility. Now the activity value of' black diamond, gold and black carbon' has exceeded the military standard. "
"It is not difficult to form activated carbon itself, but it is difficult to maintain high adsorption after forming. Because activated carbon is a small hole, any slime agent will block the hole, and the effect will definitely drop greatly. Now there is a method in Japan, that is, mixing PVC powder with activated carbon, and then molding at high temperature, but the activity has been greatly reduced. The advantage of' black diamond and dark carbon' is that carbon is shaped with special glue in a specific environment, and then this glue is converted into activated carbon through an activation process, so that the whole body is an activated carbon without other impurities. Activation is actually the most important process of activated carbon, and the quality of activation determines whether the activated carbon has good adsorption performance in the future. Black diamond and dark carbon have many obvious advantages: first, it does not need electricity, and it is completely absorbed by the flow of molecules; Second, pure physical adsorption will not produce chemical pollution. In addition, the life cycle of' black diamond and black carbon' is relatively infinite, because it can be regenerated. Because powdered activated carbon is a split and independent individual, when they are all fused, it becomes a network, and its adsorption capacity will be greatly increased. When it becomes a space, we can use recycled equipment to clean the adsorbent, which is equivalent to emptying the trash can and reusing it. A charcoal carving handicraft can generally be used for 10 to 15 years, of which the best use period is 3 years, and consumers can send it to us for reactivation after 3 years to realize recycling. "
Activated carbon is a microcrystalline material made of carbon, with black appearance, developed internal pore structure, large surface area and strong adsorption capacity. There are a large number of invisible micropores in activated carbon materials, and the total internal surface area of micropores in 1 g activated carbon materials can be as high as 700 square meters to 2300 square meters. That is to say, in a grain-sized activated carbon particle, the inner surface area of micropores is equivalent to the size of the inner wall of a large living room. It is these micropores that enable activated carbon to "capture" all kinds of toxic and harmful gases and impurities.
