Does the charcoal of bamboo suck formaldehyde? Except that corrupt may turn into pollution
Put the charcoal of bamboo in formaldehyde steam almost saturated, the absorbing amount of formaldehyde of the bamboo charcoal of each gram is up to 68 milligrams. Put the bamboo charcoal which sucks all over formaldehyde into the clean room, formaldehyde will volatilize rapidly, the formaldehyde content in the bamboo charcoal of each gram can drop to 1.6 milligrams in 3 hours. Look for and cut at home Right, when doctor's new family has just finished fitting up botany of Ins of plant,Academia Sinica, the wife has bought several big pack of bamboos charcoal to put indoor to purify the air, it is said, the not merely all right peculiar smell of absorption of thing, still can absorb invisible formaldehyde, especially have specially good effect to formaldehyde. Finally, have also seen that upgrades the edition, the charcoal of bamboo can also be made into the handicraft, while meeting you and appreciating art, they " sweep " the air silently Clean. Is the ability of the charcoal of bamboo really magical like propagating in the advertisement? Claim in some advertisements, the charcoal of bamboo has very strong absorption ability on formaldehyde, and there are experiment evidences. But the condition of these experiment can allow doubting in life, they all put the charcoal of bamboo in formaldehyde steam that is almost saturated and carry on, each gram and absorbing amount of formaldehyde of up to 68 milligram of bamboo charcoal is measured in this state, such an environment, throwing into a piece of wood at will can be smoked into formaldehyde flavor too. The key problem is whether the charcoal of bamboo can lock the formaldehyde, the experimental result is disappointing, put to once these full bamboo charcoal which suck formaldehyde does not have in spare room that formaldehyde pollutes, formaldehyde above will be released rapidly, the formaldehyde content in the bamboo charcoal of each gram can drop to 1.6 milligrams in 3 hours - --Getting rid of the corrupt products turns into pollution sources quickly. What is called the intersection of bamboo and the intersection of charcoal and the intersection of absorption and ability, the the intersection of indefinible form and carbon (different from diamond those kind of crystal carbon mainly, though chemical composition is the same) China has much size with one micron of capillary structure calculated. Just as oozing in the sand in hydroenergy. These compositions can be oozed into these inside of narrow passage of the charcoal of bamboo on the formaldehyde, water. However, just as experiment revealed, except accommodate formaldehyde in the narrow passage, the charcoal of bamboo does not have a special mechanism to limit their freedom, just as that water can be evaporated from the sand clean, formaldehyde can volatilize from the charcoal of bamboo out too. The scientific research personnel carrying on the charcoal of bamboo and absorbing formaldehyde experiment point out too, the active charcoal is not stable in absorption of formaldehyde, do not even combine closely as with the moisture son. To put it briefly even if, if the indoor vapor is numerous, can also crowd formaldehyde adsorbed onto charcoal of bamboo. Certainly, if add some materials that can react with formaldehyde in the narrow passage of the charcoal of bamboo, can make into the real absorption material, but unable to do as for present technology. A lot of advertisements intend to cover these questions, declare the special " absorption efficiency " of active charcoal material such as the charcoal of bamboo generally ,Quoting a remark out of its context more, preten to be ignorant. As for formaldehyde, can deal with some for green plants such as the Chlorophytum comosum,etc., these plants can use formaldehyde absorbed as formating raw materials of organic acid, candy and amino acid, store in the body, it is the real absorption. Certainly, the ornament materials preventing the formaldehyde content from being high as much as possible is the safest tactics.
