In addition to formaldehyde, the most important thing for formaldehyde is prevention, not governance.
That is to say, in the process of decoration, Chengdu formaldehyde should be used as little as possible with formaldehyde containing building materials to release hidden dangers. For example, all kinds of glue, artificial board, composite floor, panel furniture, putty, paint, latex paint and so on must choose products with better environmental protection indicators within the scope of economic capacity.
Where does Chengdu Norformaldehyde Formaldehyde come from? Why ten years? Formaldehyde comes from phenolic or urea-formaldehyde resin, which is the glue we use in board furniture or thick wood boards. It will decompose into free formaldehyde at room temperature.
Partial Formaldehyde Removal Formaldehyde: You may have heard of the following ways to remove formaldehyde: water, vinegar, black tea, tea stalks, grapefruit peel, pineapple, etc. The basic effectiveness of these methods is close to zero, and there is nothing.
Adsorption of formaldehyde by bamboo charcoal, activated carbon and diatom mud: adsorption? Yes, but there are two conditions. One requires air flow to allow formaldehyde to reach these adsorption carriers. Second, the contact area should be large. But the problem with adsorption is that it is released after saturation. So if you buy enough charcoal every day to replace it, it's theoretically possible.
Green plants absorb formaldehyde: Some green plants absorb formaldehyde. For example, ceiling orchids. Studies show that if 100 square meters, the bedroom inside is 3 meters high, and the concentration of formaldehyde is 0.5 mg/cubic meters, ceiling orchids need to work for one year to absorb formaldehyde free of charge. This is not the continuous release without calculating the number of boards. That is to say, there are dozens or hundreds of orchids hanging in your house.
Photocatalysts decompose formaldehyde: If adsorption does not work, can formaldehyde always be decomposed? Photocatalysts (usually nano-titanium dioxide) can decompose formaldehyde into water and carbon dioxide. The working condition of photocatalyst is to receive ultraviolet radiation, that is, the room must turn on ultraviolet light or have strong direct sunlight when photocatalyst is treated. Formaldehyde treatment institutions mainly use this.
In fact, the most useful method is dilution method. Formaldehyde concentration is low and safe, dilution is the most commonly used method, it is ventilated. In fact, there are many kinds of ventilation, such as opening windows, using fresh air system, using exhaust fans and so on.
Under the conditions of high temperature, high humidity and negative pressure, the decomposition rate of formaldehyde will increase.
The amount of glue water in wood-based panels is also limited, so there is a total amount of formaldehyde that can be released. How can we speed up the release? High temperature, such as summer or indoor air conditioning and heating; high humidity, open humidifier; negative pressure, in addition to window ventilation, you can spend about 300 yuan to buy an exhaust fan for ventilation.
Netizens suck air outdoors with exhaust fans
Someone tested in their new home, turned on the air conditioner, humidifier, 520 m?/h exhaust fan ventilation, 24 hours uninterrupted, after 10 consecutive days formaldehyde concentration reduced by half.
Some people say that it's not a lampblack that can smoke? Yes, but unfortunately, the lampblack can only blow the kitchen wind away.
Personal Suggestion: We should also focus on prevention and reduce the introduction of pollution sources. Later ventilation control is the most effective, conditional can install new ventilation system, so that the conditions without windows can also achieve the effect of partial ventilation. If you don't have a budget, you may want to try an enhanced version of indoor heating, humidification and ventilation.
