1. Air Purifying Activated Carbon is good, but it cannot be over-reliant
Indoor air purification, activated carbon can play a certain effect, but can not be completely dependent. As a treatment of the dead zone, it is more appropriate to consider: the use of environmentally friendly materials, indoor air circulation and exchange, etc.
2. Although activated carbon can be regenerated, ordinary people should not consider saving money.
There are many methods for regenerating Powder Coal Activated Carbon, but they all belong to the industrial category, such as heating regeneration method (800 to 900 ° C), biological regeneration method, wet oxidation method, solvent regeneration method, electrochemical regeneration method, catalytic wet oxidation method, and the like. Regarding the problem of activated carbon regeneration, ordinary people have no way to regenerate their own activated carbon. Sun drying, washing and even baking in the oven will not help, the price of activated carbon is not expensive, or buy new ones in time.
3. The adsorption capacity of activated carbon is large, but it is not suitable for long-term use.
Some friends buy activated carbon and often use it in a drawer for a long time. On the one hand, it is believed that activated carbon has strong adsorption capacity and potential for digging; on the other hand, it is considered that the taste has not been eliminated and needs to be continued.
In fact, there is an important parameter index of activated carbon--the saturation adsorption amount, that is, the adsorption is no longer effective when it is full; at the same time, the adsorption of activated carbon is mostly physical adsorption, which is reversible, that is, the adsorption will be full of harmful substances. come out. Studies have indicated that the use time of adsorbed activated carbon after home decoration should be controlled within 30 days. For the health of you and your family, the activated carbon should be replaced in time.
