In many decorative materials, more or less chemical substances harmful to the human body are contained. At present, many consumers are concerned about the content of harmful substances in materials. In fact, this idea is biased. Because as long as the harmful substances in the decorative materials are sealed in the materials and are not emitted into the indoor air, they generally do not cause harm to the human body. Therefore, consumers should pay attention to the amount of air released by harmful substances in decorative materials.
The true concept of environmentally friendly materials
At present, the environmentally friendly decorative materials on the market are not without harmful substances, but the content or release of such substances is lower than the national standard. Environmentally friendly materials are indeed safer than normal materials if they are used normally or if they are used in small areas. However, if the consumer uses it improperly or exceeds the standard, environmentally friendly materials will also pollute the indoor air, thus affecting human health.
Many factors affecting indoor air
In fact, in the home, temperature, humidity and air flow rate will affect the release of harmful substances in the decorative materials. For example, the higher the temperature and humidity in the living room, the faster the harmful substances in the material can be emitted; and the good ventilation conditions in the room can take harmful substances away and reduce the damage to the human body.
Limited environmental protection
For home improvement, environmental protection can only be limited to environmental protection, and there is no absolute environmental protection. First, the decorative materials on the market are difficult to achieve absolute environmental protection. For example, chemical products like paints cannot achieve absolute environmental protection. Second, materials that can achieve environmental protection are not complete.
Environmentally friendly materials and environmentally friendly materials
Environmentally friendly materials and environmentally friendly materials are two concepts. Environmentally-friendly materials refer to materials that have passed the certification of national authoritative testing institutions and meet environmental protection standards. Environmentally-friendly materials refer to materials with improved environmental performance and relatively high environmental protection indicators for similar products of the same brand. Like the exhaust emissions of a car, different emissions determine its different environmental indicators.
How big is the harm of non-environmental products to the human body?
The harm of home decoration to the human body is mainly air pollution. The main sources of pollution are formaldehyde, ammonia, benzene and radioactive elements of natural stone. The most harmful to the human body is formaldehyde and radioactive elements.
The emission of formaldehyde is slow, and it will not be volatilized in the room for a long time. The radioactive elements are not only invisible, intangible, but also smellless and odorless, so once the excessive release causes damage to the human body, I figured it out. Formaldehyde is mainly found in materials such as sheet metal and adhesives; radioactive elements are mainly found in various natural stone materials; as for harmful gases such as benzene present in paint materials, they can be emitted in a short time because of their rapid evaporation. When the owner stays, the harmful gas has been emitted almost, so the harm to the human body is correspondingly small.
As for the coatings, according to relevant experts, the current imported and joint venture products on the market are generally more environmentally friendly, but the key is that there are too many fakes on the market. General brand products designated stores have product certification documents, and have corresponding professional services, the price of their products also have a certain standard, you should pay attention to the above points when buying paint, to avoid the harm caused by buying fakes As long as the home decoration materials are qualified products, the content of these harmful substances is up to standard, and it will not cause too much damage to the human body.
Environmental testing
From the current point of view, the state still lacks a specialized authoritative testing organization, and there is still no uniform standard for environmental protection. At present, environmentally friendly products on the market are actually tested by some service agencies, and their environmental protection claims are not authoritative.
Environmental protection requires cost
From the current market point of view, the price of environmentally friendly products is often higher than that of similar non-environmental products. Therefore, if environmental protection is to be pursued, consumers will have to pay a higher economic cost. Nowadays, many consumers are used to visiting the refurbishment of the acquaintances during the renovation, to see the effects of the experience, and then go to the decoration city to find the decoration company design. Because it is mostly free design, it is better to be more good, and choose a few homes to design at the same time, and then take advantage of the long-term short-term plan, and finally decide which one to decorate by price.
Simply put, it is the combination of style + price, the price factor plays a decisive role here. In fact, home decoration workers and materials are sloppy, cheap and good, and environmentally friendly home decoration can only be the wishful thinking of consumers. In particular, the environmental protection in the home improvement not only requires the main material to be good, but also the fine details of the glue, putty and so on.
