Jinan professional formaldehyde detection: the key to indoor formaldehyde is prevention, not renovation. In other words, in the whole process of indoor decoration, we should use less decorative building materials which have potential safety hazards of formaldehyde emission. For example, various kinds of strong glue, composite board, solid wood composite floor, custom furniture, putty powder, paint, wall paint and so on, we must choose environmental protection within the scope of economic development. Commodities with stronger indicators.
Where did the indoor formaldehyde come from? Why did it release for nearly 10 years? The source of formaldehyde is urea formaldehyde resin or melamine formaldehyde resin, that is to say, the strong glue that people use to customize furniture or boards. It will gradually dissolve the indoor formaldehyde in mineral acid at room temperature.
Folk formulas for removing formaldehyde: You may have heard of the following methods for removing formaldehyde: water, vinegar, black tea, tea stalks, grapefruit peel, pineapple and so on. The basic effectiveness of these methods is close to 0, which is of little use.
Bamboo Carbon, Activated Carbon and Silicon Bath Adsorb Indoor Formaldehyde: Can you? Yes, but there are two standards. One must be gas flow to allow indoor formaldehyde to touch this adsorbing plasmid carrier; the second is the total area of contact. But the shortcomings of adsorbing are that it will release after saturation. In other words, you can buy enough activated carbon every day, which may be a little useful in theory.
Green plants absorb formaldehyde: some green plants have absorption function for formaldehyde, such as Chlorophytum. Some studies have shown that if the formaldehyde concentration is 0.5mg/m3 in a room with 100m2 and 3M storey height, one Chlorophytum needs to work for one year to absorb free formaldehyde, which is not counting the amount of continuous release of plates. That is to say, you can raise dozens or hundreds of Chlorophytum at home, which may be a little useful in theory.
Photocatalyst decomposes formaldehyde: if adsorption is not good, it can decompose formaldehyde? Photocatalyst (generally represented by nano-sized titanium dioxide) can decompose formaldehyde into water and carbon dioxide. The working conditions of photocatalyst are ultraviolet radiation, that is to say, when using photocatalyst to treat the house, it needs to turn on ultraviolet light or have strong direct sunlight. This is basically used by formaldehyde treatment institutions.
In fact, the most useful method is dilution. When the formaldehyde concentration is low, it is safe. The most commonly used method of dilution is ventilation. 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 and emission of formaldehyde will be accelerated.
The amount of glue in wood-based panels is also limited, so there is a total amount of formaldehyde released. How can we speed up the release? High temperature, such as summer or indoor air conditioning heating; high humidity, humidifier; negative pressure, in addition to window ventilation, you can spend about 300 yuan to buy an exhaust fan for outdoor ventilation.
Some people have tested it in their new home. The air conditioner, humidifier and exhaust fan with 520 m3/h air flow are turned on for 24 hours without stopping. After ten consecutive days, the concentration of formaldehyde is reduced by half.
Some people say that it is not lampblack machine can smoke? Yes, but unfortunately lampblack machine can only smoke kitchen wind.
How to reduce formaldehyde pollution? Personal suggestions: or prevention-oriented, reduce the introduction of pollution sources. Later ventilation control is the most effective, conditional can be installed fresh air system, so that part of the ventilation effect can be achieved without windows. Without this budget, perhaps you can try this indoor heating, humidification and exhaust enhanced version ventilation method.
