Pursuing home improvement and environmental protection is a good wish of the decoration households, but it is also a gimmick made by many manufacturers for profit. Some companies are researching and developing environmentally-friendly building materials on the ground, but there are also “pseudo-environmental†companies that only pay attention to the eyes of consumers. This week, the reporter listed the untrue propaganda of the furniture and building materials on the environmental protection effect for consumers, and reminded the decoration households.
Plate "zero formaldehyde" is just a concept
Formaldehyde is the main pollutant in interior decoration. The hazard of formaldehyde is also well known and has become a major factor in the decoration of consumers. In recent years, the concept of “zero formaldehyde†has become popular in the home furnishing industry. Many brand sales people will say that they use green materials, and even some furniture and building materials are marked with the "zero formaldehyde" banner. However, industry insiders said that the so-called "zero formaldehyde" of the merchants only does not use formaldehyde-containing glue or artificial formaldehyde in the production process, but the products produced cannot guarantee that they do not contain formaldehyde. The higher the environmental protection level of the board used for furniture, the less the formaldehyde content, but the amount of furniture will also affect the amount of formaldehyde released. Too much quantity may also lead to excessive formaldehyde emission. It is understood that the formaldehyde volatilization cycle is more than five years, but some of the poor quality materials will have a formaldehyde evaporation period of more than 15 years. Therefore, not only when buying furniture, but also pay attention to whether the environmental protection of the product is up to standard, do not rush to stay after the decoration, but also let the formaldehyde release through ventilation.
Scrub-resistant wallpaper is not environmentally friendly
Nowadays, many home decoration choices are wallpapered. The cleaning problem of wallpaper has always plagued consumers. Some merchants have used scouring to attract purchases. But in fact, the most scrub resistant is PVC wallpaper, which is the most environmentally friendly, and has a distinct plastic taste, while non-woven, pure paper wallpaper is relatively safe and environmentally friendly, but not scrub resistant. The degree of scrubbing of wallpaper depends first on the material, and secondly on the craft, so choosing an environmentally friendly wallpaper requires compromise in scrubbing.
VOC-free coating affects viscosity
VOC is a volatile organic compound. The definition in the environmental sense refers to a kind of volatile organic compounds, that is, the kind of volatile organic compounds that cause harm. Some merchants will use VOCs to promote the environmental protection of paints. VOC is an important component of coating film formation. If the content is reduced, the viscosity of the coating will be relatively reduced, and powder, blistering, cracking, etc. will occur after painting. In fact, the state has mandatory standards for VOC content of coatings, and coatings that meet the standards can be marketed, and this content is harmless to the human body. So don't blindly buy so-called VOC-free coatings.
Antibacterial health effects of tiles are not credible
The raw materials of ceramic tiles are mineral powders such as stone powder, quartz powder, long sand powder and zircon powder. These raw materials emit a special kind of radiation during the metamorphosis process, which in turn generates radiation. In order to make the tiles more beautiful, various materials are added in the processing, such as glazed tiles, which are applied with a layer of glaze on the tile base. Most of these glazes are derived from potassium-containing minerals such as feldspar and mica. Minerals contain certain radioactive materials such as uranium and potassium. Generally, there are traces of radioactive radiation in ceramic tiles, but the radiation of qualified ceramic products is controllable and has no harm to human health. However, for some manufacturers, the antibacterial and health-care ceramic tiles are mostly gimmicks. Consumers should also be cautious when purchasing. When purchasing home-made ceramic tiles, they should pay attention to the selection of Class A standard products. Install the position, pay attention to ventilation and ventilation.
The purification effect of diatom mud is related to thickness
Diatom mud is an interior wall environmental protection decoration material with diatomaceous earth as the main raw material. It has functions of eliminating formaldehyde, purifying air, regulating humidity, releasing negative oxygen ions, fire retarding, self-cleaning of walls, sterilization and deodorization. Many companies have introduced diatom mud wallpaper, diatom mud sheet, diatom mud purifier and other products. Some merchants will tell consumers that diatom mud is added to the diatom mud wallpaper to absorb and decompose formaldehyde. But in fact, diatom mud needs to reach a certain thickness, can effectively absorb formaldehyde, add diatom mud in the wallpaper, the effect is basically minimal, similarly, for the so-called diatom mud purifier spray on the ground wall The idea that it can purify the air has yet to be verified. Some manufacturers said that the diatom mud plate produced not only replaces wooden furniture, but also absorbs formaldehyde and purifies the air. However, in fact, diatom mud must be exposed to the air to absorb harmful substances. After the furniture is made, the surface cannot cover other materials. Direct contact with air does not purify.
The adsorption effect of the air purifier filter is drastically decreased after saturation
In the past two years, air purifiers have become popular among consumers' homes. The initial air purifier was mainly targeted at PM2.5, dust, animal hair, pollen, secondhand smoke, bacteria and so on. Later, with the emphasis on formaldehyde hazards, many air purifiers have sold the selling point of formaldehyde purification. But is the air purifier really effective in purifying formaldehyde? It is understood that the filter is ineffective for formaldehyde, and the air purifier equipped with activated carbon filter has adsorption effect on formaldehyde, but once the filter reaches saturation, it loses the adsorption of formaldehyde, and may not replace the filter in time. Lead to secondary decontamination of formaldehyde, so use the air purifier to replace the filter and filter.
