The four major sources of formaldehyde lurking in home decoration
Formaldehyde has been identified by the World Health Organization as a carcinogenic and teratogenic substance. It not only has irritating effects on skin, eyes, mouth, pharynx, esophagus and stomach, but also causes low-temperature exposure, chronic respiratory diseases, nasopharyngeal cancer, menstrual disorders, pregnancy syndrome, neonatal chromosomal abnormalities and memory of adolescents. A decrease in intelligence, etc., can also cause death at high doses.
Among all the contacts, children, pregnant women, and the elderly are particularly sensitive to formaldehyde and are more harmful. Can such dangerous elements not be able to hide? too naive! The great thing about it is that in life, you want to hide and hide, and it has invaded the corners of the family.
The four sources of latent formaldehyde, whoever is indispensable
Source 1: Glues and raw materials in artificial boards
The artificial board is made of natural wood and its corner scraps, and is made of a urea-formaldehyde resin adhesive. The adhesive itself contains toxic substances such as formaldehyde, and formaldehyde in the furniture using the sheet is inevitable.
The frightening thing is that the release of formaldehyde is a long-term process that lasts for fifteen years.
In addition to the "glue" used to contain formaldehyde, the raw materials used in the production of wood-based panels will also release formaldehyde. Such as masson pine, ash, fir, willow and other solid wood itself have different levels of formaldehyde emission.
Moreover, environmental conditions such as temperature, humidity, acid and alkali, weathering, and illumination may cause degradation of the resin that is not completely cured in the plate to release formaldehyde; and the fully cured resin may also release formaldehyde unstably due to changes in external environmental conditions. .

Reasonable use. Try not to use wooden composite panels in a large area, and consider a variety of materials for interior decoration. If too much is used, the indoor formaldehyde will exceed the standard.
Composite wood flooring is more dangerous. Common floor materials include floor tiles, natural stone, wood floors, laminate flooring, etc. Among them, floor tiles are generally not polluted, but products containing no radioactive elements should be used.
Composite wood flooring usually uses formaldehyde-containing adhesives. When purchasing, carefully check the product description and select products with low organic emission rate.
Source 2: Additives added in the production of paints, wallpapers, etc.
Interior wall paint has become one of the main materials for the renovation of thousands of homes. However, paints, paints, etc. will add various additives to improve performance in production, which becomes an important source of harmful substances such as volatile organic compounds, free formaldehyde, benzene and toluene.

Waterborne coatings are better and minimize the use of wallpaper. Especially don't brush the paint and then paste the wallpaper to avoid superimposed pollution (this is simply looking for this ). If you need to use wallpaper, you should try to use natural fabric products, such as wallpaper made of cotton, hemp, silk, etc., and use environmentally friendly adhesives.
Choose the paint to see the test report. When purchasing, look at the paint labels, instructions and test reports, and pay attention to the number of scrubs, VOC and formaldehyde content. The higher the number of scrubbing resistances, the lower the VOC, the better; in addition, the smaller the taste, the better the coating.
Source 3: more plate furniture, solid wood furniture also has
Furniture is also one of the sources of indoor pollution, especially the formaldehyde release of various sheet furniture, it can not be ignored; solid wood furniture is relatively environmentally friendly, but does not rule out the release of formaldehyde.

When purchasing panel furniture, first check the environmental performance of the board; secondly, the newly purchased furniture should open the door, pull out the drawer, ventilate on the spot, and then stay in the best after a period of time.
If you have the conditions, it is best to put the furniture in the sun before you go to the sun.
Source 4: Formaldehyde additives in textiles such as carpets
In textile production, in order to improve its anti-wrinkle and waterproof properties, or to make printing and dyeing more durable, merchants generally use some additives containing formaldehyde. Such as curtains, bedspreads, pillowcases, sofa fabrics, mattresses, carpets, etc., these are all possible sources of formaldehyde.

When selecting, it is best to buy a fabric with a high cotton and linen composition and pay attention to the smell.
If you don't want to be harmed by formaldehyde, you have to do this.
Avoid blind pursuit of luxury decoration. Also pay attention to health, try not to use large-area use of plates, large-scale ceilings, wall skirts and other decoration methods.
Choose a regular product, don't be cheap. When purchasing decoration materials or furniture, try to purchase it in the formal decorative materials market and furniture market. Ask the dealer for a test report and ask for instructions on the amount of formaldehyde and other harmful substances in the furniture.
Choose a good decoration company. During the decoration process, the construction company's construction personnel are not allowed to deal with the garbage generated by the decoration at will. If the paint is poured into the sewer, the behavior is not environmentally friendly; the remaining decorative materials should be disposed of in time after the completion of the decoration.
Do not rush to stay after renovation. Ventilation of doors and windows is a more effective way to reduce the concentration of indoor air pollution. Even if you are staying, you should always ventilate and keep enough air in the room. In addition, to maintain proper indoor temperature and humidity, the release of formaldehyde increases with increasing humidity and temperature.
