Anonymous users2024-01-23Plywood is made of three layers of veneer of different materials bonded, adhesives are used in the production, and formaldehyde exists in the adhesive, so there will be formaldehyde in the furniture made of plywood, do not take it lightly, formaldehyde can cause respiratory and nervous system diseases such as cough, sore throat, chest tightness, dizziness and nausea, weakness of limbs, difficulty breathing, drowsiness and other symptoms. More severe cancers such as nose cancer, throat cancer, skin cancer and leukemia are induced. Generally, the cycle of toxic gas activity is 1-10 years, especially in the first year, during which the toxic gas volatilizes quickly and releases a high amount, so the harm to the human body is more serious.
Excessive formaldehyde in the room is quite harmful to the human body, so it is necessary to take appropriate measures to reduce the content of formaldehyde.
1. Ventilation method.
The best thing to do is to ventilate.
2. Plant absorption method.
Plants have a strong ability to absorb formaldehyde, such as cacti, spider plant, reed, ivy, iron tree, chrysanthemum, etc. Generally speaking, plants with large leaves and vanilla have a better effect on absorbing formaldehyde, such as spider plant, tiger tail orchid, etc.
3. Methods of folk circulation.
Place tea pomace, grapefruit peel, onion slices, pineapple chunks, etc. in the newly renovated room or fumigate the whole room with white vinegar.
4. Activated carbon adsorption method.
Solid activated carbon has the characteristics of many pores, and has a strong adsorption and decomposition effect on harmful substances such as formaldehyde, and the smaller the particles of activated carbon, the better the adsorption effect.
5. Photocatalyst decomposition method.
Under the stimulation of light, the catalyst in the photocatalyst generates negative ions and hydrogen and oxygen radicals with oxygen and water in the air, which can oxidize and decompose various organic pollutants and inorganic pollutants, and finally degrade into harmless substances such as carbon dioxide, water and corresponding acids, so as to decompose pollutants and purify the air.
6. Chemical purification method.
At present, there are two types of formaldehyde scavengers on the market, one is to purify the air by neutralizing formaldehyde and generating harmless substances; The other is to purify the air by sealing formaldehyde and preventing the volatilization of formaldehyde.
You can try all of the above methods.

Anonymous users2024-01-22Plywood generally contains formaldehyde.
1.You can use decorative paper, which is cheap and easy to construct, but it looks cheaper, and it is easy to leave wrinkles and bubbles if it is not pasted well. >>>More
Comparison between the two: taking wardrobes and tables as examples, solid wood and plywood of the same material at the same level of production process (such as ash solid wood and ash plywood, only comparable), of course, solid wood is better than plywood in terms of price, value, durability and ornamentality.
The production method of multi-layer board is generally made by the inner layer pattern first, and then the printing etching method is made into a single-sided or double-sided substrate, which is incorporated into the designated layer, and then heated, pressurized and bonded, and the subsequent drilling is the same as the double-sided through-hole plating method. >>>More
That's right, the three-layer board is the three-layer board, and now it has been improved into a nine-layer board.
After the plywood ceiling is suspended, use diluted paint, brush it thinly, lay the primer, and then scrape the putty, the putty cannot be mixed with water, it must be mixed with paint. The scraped mirror putty will not fall off.
