Activated carbon is a kind of black porous solid carbon, which is produced by pulverizing, forming or carbonizing and activating coal with uniform coal particles. The main component is carbon, and contains a small amount of oxygen, hydrogen, sulfur, nitrogen, chlorine and other elements. The specific surface area of ordinary activated carbon is between 500 and 1700m2/g. It has strong adsorption performance and is a widely used industrial adsorbent.

How to make activated carbon adsorb formaldehyde effectively? To use ventilation and ventilation, in addition to stacking activated carbon at the source of the release, it is also necessary to measure its concentration frequently, and it is necessary to replace it if it is found to be saturated. One point first. The formaldehyde in the renovated home is a process of continuous release. This shows that the control of formaldehyde pollution is also a continuous process.

Where does formaldehyde in home decoration mainly come from? A large part of it comes from the cheap glue in the artificial board – urea formaldehyde resin (as long as it is not a raw wood, it can be considered as artificial board, composite floor,) In addition, gypsum board, paint, plastic products, adhesives are also in It is possible that it contains formaldehyde, just to say that it is much lower compared to the amount of artificial boards. Therefore, activated carbon needs to be placed for a long time and adsorbed for a long time in order to have good purification results.
