Last Thursday, Wenzhou Metropolis Daily's home version launched the "2012 home environmental quality line" activity, many people who are preparing to decorate or just finished renovation have passed this version of the hotline to consult whether their home decoration is environmentally friendly. From the hotline, we found that the decoration industry is a professional industry. The general public said that they can't understand the decoration. How to identify whether the decoration materials on the market meet the environmental protection standards, how can the new home be less polluted by the home improvement materials? The public generally said that it was not clear.
To this end, we took the questions of the general public concern of the citizens, and specially asked the person in charge of the indoor air testing room of the Wenzhou Institute of Building Quality Supervision. Professionals remind consumers to reduce the pollution of interior decoration from the source, to add environmental protection knowledge of building materials before purchasing materials, and strictly control the quality of building materials. After the renovation, it is best to do environmental monitoring for the new house. At the same time, pay attention to ventilation for the newly renovated house and speed up the scattering of pollutants.
Radioactive detection eliminates invisible killers
Many people in the hotline said that they have doubts about whether or not their home decoration is preserved. It is judged by whether the smell is strong or not. In fact, this method is very unscientific. Among the main toxic and harmful gases that cause indoor pollution, some are odorous, some are odorless, especially radiation pollution, the human body is completely imperceptible, but the harm to the human body cannot be ignored, because this pollution is lifelong. It will not reduce the amount of release over time. This kind of pollution exists in addition to natural stone such as marble and granite. Some tiles may also have radiation pollution, mainly because some tile manufacturers are pursuing decorative effects for one-sided pursuit, improving the whiteness of the base color of the brick and the contrast of decorative colors, and adding some radioactive minerals excessively in the raw materials of the tiles, resulting in The radioactive dose level of the product exceeded the standard.
For the radiation pollution problem of ceramic tiles and stone, the best way to eliminate the problem is to ask the merchant to provide relevant test reports when purchasing. However, considering the batch problem, the most insured way is to take the sample from the sample before sending it to the local. The qualified department conducts tests on radiation, and the test content is divided into two parts: the internal exposure index and the external exposure index.
Auxiliary materials can not be ignored
In the decoration, all-purpose glue, white glue, sheet and so on are indispensable, but whoever thought that the main cause of indoor environmental pollution is sometimes not the main material of the surface, but the auxiliary materials hidden underneath. Consumers generally know that formaldehyde is present in unqualified laminate flooring. This is mainly because adhesives are used in the production of flooring. If the formaldehyde in the adhesive exceeds the standard, the formaldehyde in the floor will exceed the standard. Formaldehyde may also be present on artificial boards such as fine wood boards, medium density fiberboard and particleboard used in ceilings, walls, etc., as well as curtains and chemical fiber carpets. In addition, some furniture made of wood-based panels will release harmful substances such as formaldehyde, xylene and TVOC into indoor air due to the use of unqualified plates and inferior glue. What needs to be reminded here is that many decoration companies or engineering teams use gypsum powder and glue to level and fill the wall before applying latex paint. It is easy to use pollution when using glue on a large area. Use environmentally friendly putty because this material only needs to be mixed with water.
Environmental testing should start from the source
Many newly renovated citizens call and hope to participate in indoor environmental testing so that they can stay at ease. At the same time, it is said that if the test fails, what material is caused by it, or because of the superimposed pollution of the material, how to judge. For this problem, environmental testing experts said that the responsibility is not well-recognized, so the best way is to prevent in advance, buy products with environmental testing certificate, the safest way is to send the products you purchased to the local testing department for testing, in case If the test fails, you can directly request the merchant to return the goods or even claim the loss. Experts also reminded that for houses that have been renovated and failed to pass the test, they can only adopt some methods to repair the dead. For example, do not rush to stay, leave as much ventilation as possible, especially in summer, and maintain good ventilation to facilitate the discharge of harmful gases. In addition, there are various methods for indoor environmental management in the market, and there are many types of air purification machines. The real effect is not long-term tracking and testing. It may only be a short-term suppression of harmful gas release. The public should carefully purchase.
