Identify the authentic of environmentally friendly building materials

“Green Decoration” has been used for many years and has been abused by many businesses for many years. Even so, there are still many owners who were deceived by some bells and whistles during the renovation, and waited for them to wake up and regret it.
Below, we will use the theme of “fake environmental protection” building materials to count the “environmental protection” gimmicks that are easily overlooked.
Interior wall paint can not absorb formaldehyde
When the reporter visited Taiyuan's large-scale home store, many merchants said that their own wall coatings are environmentally friendly, which can effectively absorb formaldehyde, benzene and even bacteria in the air to purify indoor air. Most of these products are much more expensive than similar general products.
The reporter learned that in recent years, many well-known paint brands have successively launched "anti-formaldehyde" and "purified air" coating products. Consumers who are plagued by various types of decoration pollution recognize these "new" products and use this promotional point as a major factor in considering purchases.
However, the reporter consulted the sales staff "What is the principle of anti-formaldehyde? How much can the indoor formaldehyde absorb?" When almost the specific problem, almost all the merchants did not clearly answer, indicating the specific analysis of the specific situation, no specific test data to support.
The relevant staff of the Shanxi Interior Decoration Association said that the China Coatings Industry Association had reminded such products. As a building interior wall paint, “anti-formaldehyde” is only an auxiliary function, and consumers should never be fooled by it. It’s not an important concern, and it’s not appropriate for businesses to focus on promoting this feature.
The reporter learned that after the coating was applied, the wall surface formed a thin coating film, and the amount of formaldehyde adsorbed or degraded by this film was limited. When the film is dried to form a solid surface coating film, the formaldehyde purification agent inside the coating can not combine with the formaldehyde in the air, that is, only the formaldehyde purification aid on the surface of the coating can be in contact with formaldehyde. Play a role. Secondly, the formaldehyde in the home is released for life. Whether the formaldehyde purification in the coating can last for a long time is still inconclusive, but the formaldehyde purification aid on the surface of the coating will be ineffective for a long time. Without the addition of new additives, it can no longer be played. Anti-formaldehyde function.
“Multi-functional” tiles are mostly just publicity
In the decoration of building materials, all wood products may emit formaldehyde, in contrast, the environmental performance of tiles is higher. Therefore, in the ceramic tile market, “environmentally friendly” ceramic tiles have become popular among star products. In the category of “environmentally friendly” ceramic tiles, the names of various new materials are dazzling: microcrystalline stone, ultrafine powder, polycrystalline micropowder... All these tiles are labeled with environmental health and health, such as fatigue relief, health care , antibacterial and no radiation.
“The sales staff can’t figure out what the principles of these complex functions are and how they can be achieved.” Industry insiders said, “In fact, the so-called various environmental functions are promotional gimmicks. If these functions are true, then the products are in mass production. Before the rigorous multiple inspections, it is determined that there are data changes before and after the installation of the tiles, and a reliable test report is formed to prove the effectiveness and reliability of its environmental protection function."
Plate furniture beware of contaminated wooden boards
In recent years, panel furniture with various styles, complete functions and low prices has occupied a large part of the market share. It should be noted that the “board” of panel furniture often becomes the “culprit” of home interior decoration pollution.
It is reported that the wood boards commonly used in panel furniture are MDF, particle board, etc. Most of these boards are made of wood. Due to the use of a large number of adhesives, environmental hazards are created. Some small manufacturers use medium-density boards and particle boards produced from raw materials that do not meet environmental protection standards, which is the most inferior board furniture.
Some consumers who are more environmentally conscious will usually notice this when purchasing panel furniture. However, some merchants have also proposed particle boards and particle boards for “environmental protection panels”. In fact, this type of sheet is another name for medium density board and particle board. If the standard does not meet the standards in the production process, such furniture will not only achieve the effect of environmental protection, but may cause the user to have a reassuring mentality, so that the window ventilation is not performed, resulting in more serious consequences.
When purchasing wooden floors and wooden furniture, it is necessary to see whether the product has a test report of an authority above the provincial level, and the test report must be the quality inspection department at the place of sale. Wood lacquer must comply with GB18581-2001 "Residential materials in interior decoration materials, solvent-based wood coatings". In addition, the furniture must provide a product specification, which is mandatory. The formaldehyde emission of wood is the national standard E1 grade, that is, the formaldehyde emission is 0.5mg/I-1.5mg/I; the E1 environmental protection standard is the national mandatory health standard, and the wood below the E1 grade is illegal production.
No taste is not the same as environmental protection
In the large-scale home store, many sales people will promote their products with environmental protection standards by “no taste, absolutely environmental protection”. However, industry insiders pointed out that it is not rigorous to judge whether furniture and materials in the home are environmentally friendly simply because of the strong smell. Among the main toxic and harmful gases that cause indoor pollution, some have odors, while others have no odor.
When purchasing products, consumers should pay attention to any product name, execution standard number, production location, model, specifications, and instructions for use. Well-known brands should be accompanied by a national exemption certificate, a famous brand certificate and a Chinese well-known trademark mark. On the basis of taking these measures well, let’s take a closer look at whether the home is environmentally friendly.
