Does the carpet contain formaldehyde?
Yes, when the carpet is used, it will release formaldehyde and other organic chemicals such as acrylonitrile and propylene into the air. Another hazard of carpet is its strong adsorption capacity, which can adsorb formaldehyde, dust, pathogenic microorganisms and other harmful gases. Especially the pure wool carpet is an ideal breeding and hiding place for dust mites.
Backing materials used in carpet manufacturing are made of water-soluble rubber, such as styrene-butadiene latex and natural latex, which have strong adhesion. These adhesives will volatilize a lot of organic pollutants when used, mainly including phenol, cresol, formaldehyde, acetaldehyde, styrene, toluene, ethylbenzene, acetone, diisocyanate, vinyl acetate and epichlorohydrin, among which benzene and benzene series are the main pollutants.
Harm of carpet to indoor air
Carpet is a kind of interior decoration with a long history. Traditional carpets are made by hand from animal hair. At present, the commonly used carpets are all made of chemical fiber. Chemical fibers used to weave carpets include polyacrylamide fiber (nylon), polyester fiber (polyester), polypropylene fiber (polypropylene fiber), polyacrylonitrile fiber (acrylic fiber) and viscose fiber. When carpet is used, it will have adverse effects on indoor air:
( 1)? Release and breed harmful gases and substances. Chemical fiber carpets will release formaldehyde and other organic chemicals such as acrylonitrile and propylene into the air. Another hazard of carpet is its strong adsorption capacity, which can absorb formaldehyde, dust, pathogenic microorganisms and other harmful gases, especially pure wool carpet is an ideal breeding and hiding place for dust mites. A foreign scholar found that indoor carpet laying has a certain relationship with the occurrence of cancer in residents, which was later proved to be mainly related to the absorption of carcinogenic polycyclic aromatic hydrocarbons in rubber-soled shoelaces by carpets.
(2)? Water-soluble rubber, such as styrene-butadiene latex and natural latex, is used as the carpet backing material, which has strong adhesion and the synthetic rubber pollutes the surrounding air seriously. These adhesives will volatilize a large number of organic pollutants, mainly including phenol, cresol, formaldehyde, acetaldehyde, styrene, toluene, ethylbenzene, acetone, diisocyanate, vinyl acetate, epichlorohydrin and so on. Benzene and benzene series are the main pollutants.
(3)? Carpets can cause skin allergies. The fine wool of pure wool carpet is an allergen, which will be damaged to some extent due to constant friction during use. The released fine wool can cause skin allergy and even asthma.
The advantages and disadvantages of indoor carpets, good and bad, readers will have a preliminary understanding by reading the above articles. Carpet materials contain organic chemicals, which will continuously release harmful gases if left indoors for a long time. Therefore, if you place a carpet at home, you must pay attention to cleaning and ventilation, kill the germs of the carpet, and maintain good indoor ventilation. In addition, if you are allergic to carpet materials such as pure wool at home, it is best not to use indoor carpets to avoid harm to your body.
