Adhesives must be used when bonding woodwork, wallpapering, and wall coverings in home renovations. Although different adhesive compositions are different, due to the presence of halogenated hydrocarbons, formaldehyde and benzene, improper use or use of substandard products will have an impact on the indoor environment.

Adhesive is indoor

Primary source of formaldehyde

It is understood that the release of formaldehyde in the adhesive lasts for 3 to 15 years. Once the adhesive with poor environmental performance is used, it will bring long-term harmful pollution to the room. Song Guangsheng, director of the National Indoor Environment and Indoor Environmental Product Quality Supervision and Inspection Center, told reporters that there are many types of adhesives used in home decoration, such as polyvinyl acetate adhesive, namely white latex, which is mainly used for wood bonding; 801 glue is mainly used for Wallpaper, wall covering. Polyurethane adhesives are mainly used for bonding plastic flooring, but also for bonding steel, aluminum, glass and ceramics. Rubber adhesives are mainly used for bonding rubber products. From the physical point of view, the adhesive can be divided into two types: solvent-based and water-based adhesives. Among them, solvent-based adhesives are widely used in interior decoration because of their good initial adhesion and bonding properties, flexible and simple operation process, and easy control of production process. Polyurethane adhesives and rubber adhesives are all water-based adhesives.

When laying wallpapers and attaching cracked walls, there are many adhesives used, so it is necessary to pay special attention to its environmental performance. Toluene evaporating from the adhesive is more irritating to the skin and mucous membranes. The formaldehyde volatilization is slower, causing nausea after inhalation, causing bronchitis and even pulmonary edema; halogenated hydrocarbons are carcinogenic substances, and long-term inhalation can damage organs such as the liver.

Self-purchase adhesive

Must check the content of harmful substances

If the decoration is carried out by the home improvement company, the adhesive will generally be distributed by the home improvement company, and the owner does not have to worry about the quality and environmental protection of the adhesive. However, if you buy it yourself or purchase it from a worker, you must pay attention to whether the adhesive is environmentally friendly. It is best to buy in large building materials stores or formal building materials market.

At present, the state has clearly defined the content of harmful substances in the adhesive. In GB 18583-2001 "Limits of Hazardous Substances in Interior Decoration Materials Adhesives", consumers can find relevant regulations. At the same time, the standard also stipulates that “all adhesive products used for interior decoration materials must be marked with the name and content of the hazardous substances specified in this standard on the packaging.” Therefore, pay attention to the outer packaging of the product when purchasing, and compare the standards. Limited.

When purchasing a product, it is best for the consumer to know as much as possible about the product information of the adhesive and request a test report containing the standard name and number, sample name, production unit, batch number and sampling method applicable to the product; Use the instrument name and model, test results, and abnormal conditions that occur during the inspection.

In addition, the owner should also strengthen the supervision of the construction workers during the decoration process, paying attention to whether the adhesive they use releases a pungent odor.
