First, formaldehyde is mainly derived from adhesives and related products, such as artificial boards (plywood, fiberboard, blockboard, large core board, medium density board, particleboard, etc.), furniture, wallpaper (cloth), chemical fiber carpets, paints, coatings , Some clothing, bags and footwear, chemical smog, etc. Urea formaldehyde resin, phenolic resin or melamine formaldehyde resin are mostly used as adhesives. To prevent formaldehyde, it is the most critical one to pay attention to environmental protection when using these materials.

Second, in order to eliminate formaldehyde, dozens of products have appeared in the market recently. It should be said that these products can play a role in varying degrees, but also pay attention to when purchasing:

1, it depends on whether there is environmental protection, quality inspection, consumer associations or other qualified authoritative agencies to monitor and monitor the adoption.

2, to see if there may be secondary pollution.

3. Attention should be paid to such exaggerated propaganda as "a sweep of light", "a treatment, a lifetime benefit," and "into the wood to catch formaldehyde." Because according to the current level of science and technology, the use of these equipment (agents) to prevent and control formaldehyde pollution can only be short-term, and radically unlikely.

4. Devices of the same brand function in some places but not in others. Businesses must not only have a warranty period, but also have a useful shelf life, to track the continuous improvement of services.

5, according to the product description to use the correct removal of formaldehyde "agent".

Third, during the renovation process, even environmentally-friendly products cannot be used excessively. For example, environmentally-friendly large core boards do not exceed 20 square meters for a room size of 20 square meters.

Fourth, do a good job in six aspects of green decoration: scientific design, environmental protection building materials, standard construction, quality supervision, green supervision (testing) and appropriate flowers, of which the key is environmentally friendly building materials. For this reason, when signing a contract with a decoration company, it is necessary to order a qualified and authoritative unit to monitor the instructions after the decoration is completed, and confirm that the harmful substances in the indoor environment meet the corresponding international standards.

5. Do not use formaldehyde-exceeded core boards as liners for composite wood flooring. There have been many formaldehyde pollutions caused by this, and the pollution degree is proportional to the formaldehyde content in large core boards, and the release period is generally also relatively low. long.

Sixth, the "release period of formaldehyde from 3 to 15 years" is not scientific. The release time of formaldehyde is closely related to its required standards, content and conditions, such as temperature, humidity, air pressure, wind force, depth, hermeticity, density, and applied force. According to this, the release time of formaldehyde should be twenty to thirty days to several years. For example, one gram of formaldehyde-containing adhesive is placed on a bare glass plate and another gram is placed in a bottle and covered. Obviously, under ventilation, the former may be reduced to allowable standards within a few days. The latter may take several years under the same conditions.

7. To purchase composite wood floors and furniture, it is necessary to smell and see the safety certificate first. For example, when purchasing a composite wood floor, you should immediately take a piece of smell in the newly opened box. Exciting smells are excessive; when buying furniture, you must first read the instruction manual, and then open the door. When smelling irritating, it is Excessive standards.

VIII. After the interior decoration is completed, it takes about three weeks to ventilate and ventilate. If no odor or other abnormalities can be accommodated, otherwise a qualified and authoritative company is required to carry out inspection and treatment. If there are not many exceptions, some measures can be taken. Can continue to ventilate, ventilation, ventilation can reduce formaldehyde 50% to 70%; correct use of the above-mentioned do not produce secondary pollution to the formaldehyde meter or dosage form; due to formaldehyde dissolved in water, it can also assist the use of humidifier or use Wet rags are used to scrub formaldehyde-releasing sites to reduce formaldehyde; appropriate amounts of flowers can absorb formaldehyde and other harmful substances such as spider plants, cycads, asparagus, aloe vera and cactus. When the test confirms that the formaldehyde exceeds the standard, and the above measures are still not improved, it is recommended that the formaldehyde release location should be thoroughly treated and the test should be carried out after the treatment.
