After the house is decorated, many people choose to move in after half a year to let the harmful gases, especially formaldehyde, evaporate. As everyone knows, the volatilization time of formaldehyde is as long as 15 to 20 years. If the decoration is improper, no matter how the volatilization is completed, it is difficult to ensure that formaldehyde does not exceed the standard. So, how to prevent indoor formaldehyde pollution? ◆ control pollution sources: when selecting qualified environmental protection building materials, indoor air pollution in the process of home decoration should be prevented. First, it should be controlled from the source. Using decoration materials that meet national standards and have less pollution is an effective measure to reduce the content of indoor toxic and harmful gases. For example, selecting coatings and adhesives that meet the requirements of environmental indicators, and materials that are pollution-free or less polluting can greatly reduce the content of benzene in indoor air; Purchasing and using wood products that have been specially baked can effectively reduce the release of formaldehyde. Why did ancient furniture not have the problem of formaldehyde exceeding the standard? Because wood is generally transported by water, water will absorb a large amount of formaldehyde, and it will be fully baked, which is conducive to the volatilization of harmful gases. And modern (modern decoration effect drawing) furniture? All logs are transported in closed containers. After being transported to the furniture factory, the manufacturer generally considers the output of furniture and will not bake the wood specially. In order to leave the factory quickly, a large amount of adhesives will be used, which makes formaldehyde difficult to volatilize, and it is easy to cause air pollution after consumers buy it home. If you buy furniture that meets national standards, ask for the "furniture instructions" to see if the formaldehyde content is indicated. At the same time, pay attention to the materials of furniture, and it is best to choose furniture with high sealing degree of wood materials; Don't rush to put the newly bought furniture into the room. If possible, it's best to release the harmful gas in the furniture as soon as possible for a period of time; Try not to put underwear, pajamas and children's clothes in the newly bought wardrobe made of artificial wood; If the furniture purchased or made of large core board is found to have irritating smell and spicy eyes during use, and it is found that family members, especially children, often have skin allergy, emotional anxiety, poor diet, continuous cough and other symptoms, it should be considered that formaldehyde may be the cause of the disaster, and effective treatment methods should be taken as soon as possible. ◆ simple home decoration: to avoid the superposition of pollution, home decoration should be practical and simple, and excessive decoration is easy to lead to the superposition effect of pollution. For example, when some consumers pave solid wood floors for their new houses, they also need to pave a layer of blockboard below, in order to make the floor more flat and feel better when stepping on it. From the perspective of environmental protection, this over decoration is actually unnecessary. Once the blockboard laid on the lower layer has quality problems, formaldehyde and other toxic and harmful gases will spread and release outward through the upper solid wood floor. At that time, whether it is replaced or removed, the cost of consumers will be very high. Some families also like to stick various wall cloths and wallpaper on the wall to make the room more beautiful, but in fact, it is also easy to cause excessive formaldehyde. Why? Because sticking wall cloths and wallpaper requires a lot of glue, which is not conducive to the volatilization of toxic and harmful gases in coatings and paints, but will absorb some toxic and harmful gases. Moreover, when decorating, some decoration companies will send some glue to customers. Some consumers think it is cheap, but in fact, some glue is of poor quality, which will cause greater harm after use. In particular, the bearing capacity and ventilation capacity of indoor space should be fully considered in the design; Try to use non-toxic, less toxic, non polluting and less polluting construction technology. For example, the sawedge of wood-based panel should be coated with paint to fully solidify it and prevent formaldehyde emission in the panel; Qualified interior decoration materials are selected in strict accordance with national standards. At present, the state has formulated ten mandatory standards for the limit of harmful substances in interior decoration materials. ◆ ventilation and humidification: it can effectively absorb indoor formaldehyde, strengthen ventilation, dilute indoor air pollutants with outdoor fresh air, reduce the concentration of toxic and harmful gases, and improve indoor air quality. It is the simplest and fastest way to prevent and control home decoration pollution. If possible, consumers can also buy a humidifier and put it at home to improve the indoor air humidity and absorb formaldehyde. If there is no condition, putting more pots of water at home can also adsorb formaldehyde, but change the water in a few hours, otherwise the formaldehyde concentration in the water is too high and no new formaldehyde will be adsorbed. Just after the decoration, you can also shop some hydrated lime on the ground, or buy some activated carbon to put at home, which can also absorb formaldehyde well
