Today, "indoor environmental pollution" has become a topic that is attracting more and more people's attention. How can consumers get a correct understanding of "indoor pollution" and can effectively control and avoid indoor pollution, and create environmentally-friendly homes and healthy lives? The initiative is in your own hands. Before the arrival of the golden season, relevant experts reminded everyone to pay attention to the following points:
First of all, choosing a formal home decoration company is the first step in ensuring the quality of the project and the quality of air after the renovation of the new home. As we all know, formal home improvement companies should have business licenses issued by the Trade and Industry Bureau, certificates of decoration companies issued by the Municipal Construction Committee, or certificates of approval for home improvement enterprises. Enterprise behavior is subject to the management and supervision of the administrative department, and consumers will not encounter any problems. Evaporation. In order to seek long-term development, formal enterprises have a systematic and careful management system. From quality supervision to after-sales service, construction quality can be effectively controlled. Scientific management is the most powerful guarantee for construction quality. At the same time, in the decoration material selection, most of the formal decoration companies use integrated decoration. The company purchases the main material accessories and distributes them to the construction site, instead of handing over the material procurement rights to the construction team, thereby avoiding name-causing materials due to human factors. Failing to eliminate indoor environmental pollution from raw materials, supplemented by mature design methods for pre-evaluation and standardization of environmental protection, lay a solid foundation for environmental protection and healthy home improvement projects.
Second, sign a unified home improvement contract to protect the environmental protection project. Nanjing now uses the contract texts of the Municipal Bureau of Industry and Commerce and the Municipal Construction Commission. The contract text clearly states: "If indoor air quality fails to meet the standard and is indeed the responsibility of Party B (construction party), Party B shall return the project to Party A. "When indoor air pollution occurs after renovation, consumers can safeguard their legal rights according to the terms of the contract.
Third, the use of scientific methods to pre-evaluate the content of harmful substances in indoor air. Before the construction, the designer will make a “preparation calculation book for home improvement environmental protection†based on the home design drawings and the bill of materials. This method is to use the various types of building materials (such as sheets, adhesives, paints, coatings, etc.) The amount of hazardous substances released, using scientific calculation methods, calculate the content of harmful substances in the indoor air after completion; if the results exceed the national standards, we must adjust the design scheme reasonably, reduce the amount of materials used, or use more environmentally friendly properties. The materials prevent the possibility of exceeding the environmental standards during the design phase, and also avoid the rework caused by the environmental protection of the indoor air.
Finally, experts remind consumers to pay attention to the fact that some people think that indoor air pollution is the cause of renovation. This is only a one-sided statement. When the building’s own structure, decoration, materials, and furniture are improperly selected, it may become a cause of pollution. Therefore, when there are possible indoor pollution problems, it is necessary to find the root cause and solve the problem as soon as possible. problem. Therefore, under the premise of ensuring the decoration process, consumers must purchase the building materials and furniture, they must go to the formal market or supermarket to buy; look for products with a health certification mark at the time of purchase, and ask the dealer to meet the standards of testing The report reads the names of products, limits of harmful substances, grades, etc., and then purchases them so as to avoid environmental pollution caused by the environmental quality of the furniture or the main materials, which will cause late-stage indoor environmental pollution.
Decoration overall design should have indoor environmental awareness
Why do some consumers decorate all the selected environmental protection materials, indoor air pollution after decoration? There is a question of a design scheme that should be properly selected for decoration. Of course, the design mentioned here refers to the design of the overall structural materials and layout of the room. For example, what kind of materials on the ground floor, the wall is painted or wallpaper, the size of the furniture and the selection of materials and so on. Therefore, in determining the home decoration design program, we must pay attention to the space bearing capacity, the use of materials, indoor fresh air volume and keep a good advance in four aspects:
1. A reasonable calculation of housing space carrying capacity. Due to the fact that various decorative materials on the market will release some harmful gases, even if it meets the national standards for hazardous materials for interior decoration materials, a certain amount of indoor space will also cause harmful substances in indoor air to exceed the standard.
2. With a variety of decorative materials used. The ground material is best not to use a single material, because the ground material is used in a large proportion of interior decoration materials. If you choose a single material, it will cause some harmful substances in the indoor air to exceed the standard.
3. Ensure that there is a certain amount of fresh air in the room. According to the "indoor air quality standards" indoor fresh air should be guaranteed at no less than 30 cubic meters per person per hour. For example, the ventilation of the kitchen and bathroom, not artificially blocking the ventilation of the room, the conditional family can install indoor air blowers and ventilation air conditioners, and some residential buildings with poor ventilation should pay more attention.
4. Keep a good amount of pollution for indoor purchases of furniture and other decorative items. Because indoor air pollution is the accumulation of various pollutants in indoor air, if you buy furniture and other decorative articles, these articles will also release harmful gases, which will cause indoor pollutants to exceed the standard.
â– Pay attention to two links in the construction process: floor and wall
In the interior decoration, it is necessary to pay attention to the selection of construction techniques that will not cause indoor environmental pollution in accordance with indoor environmental requirements. This is also an important aspect to prevent indoor environmental pollution. The indoor environment testing center has detected in recent years that the problem of indoor environmental pollution caused by unreasonable construction processes is also outstanding. The current major problems of the process are mainly two aspects:
1. Flooring problems. Pavement lining under solid wood flooring and composite flooring is a traditional construction process. However, due to this process, indoor environmental pollution is very common. The main reason is that large core boards and other wood-based panels underneath the floor all contain Formaldehyde cannot be closed and ventilated, and the area of ​​use is relatively large. Others use low-grade materials, which further exacerbates indoor hazardous substances and causes indoor formaldehyde pollution that is not easily removed.
2. Problems with wall finishes. According to the requirements of national regulations, in the case of wall finishing projects, primary treatment and brushing of interface agents shall be carried out to prevent wall peeling or cracks. However, some construction workers use brushed varnish to perform the primary treatment, and most of them use low-grade varnish. In addition, a large amount of thinner was added to the brushing process. This inadvertently caused serious indoor benzene contamination. Since it was enclosed in putty and wall paint, it would volatilize in the room for a long time and it was difficult to remove.
â– Choose three types of interior decoration materials
Although home decoration is not a large-scale construction project, there are also many materials in all aspects. How to choose non-polluting materials has become a headache for home decoration. The state has introduced ten kinds of control standards for hazardous substances in interior decoration materials for protection. The interests of consumers regulate the interior decoration materials market provides a basis. Everyone must choose strictly according to national standards when purchasing. From the current general home decoration, the focus should pay attention to the following three types of decorative materials:
One is stone tiles. Such materials should pay attention to their radioactive contamination, especially some natural stone such as granite. The content of radioactive material is relatively high and should be selected strictly in accordance with national standards. If the dealer does not have a test report or the consumer does not trust, he can also take a piece of it. Samples to the indoor environment detection unit for radioactive detection.
The second is paint coatings. Such as furniture lacquer, wall lacquer and various adhesives used in decoration. This kind of material is the main source of benzene pollution in indoor air. There are many problems on the market. The majority of consumers are not easy to choose. Consumers should pay attention to selecting products produced by regular manufacturers. It is best to go to the store established by the manufacturer to purchase.
The third is wood panels. For example, all kinds of laminate flooring, large core boards, plywood, and density boards are the main sources of indoor formaldehyde pollution. Everyone should pay attention to the choice of brand and the choice of external quality when choosing. They can also compare prices.
â– To ensure indoor air quality, you have to be a confident person
1. Add a sentence when signing the contract. When signing contracts for the purchase of homes, decoration and purchase of furniture, consumers must add the sentence “must meet the national indoor air quality standards†if there is no indoor environment in the original contract.
2. Leave a sample after purchasing the material. When purchasing interior decoration materials or decorating companies to purchase materials, it is best for consumers to leave a sample, and once the project is over, the problem of indoor environment pollution can be found, which can be used as the basis for judging the responsibility.
3. An indoor environment test report is required for acceptance of the project. According to the standard, civil construction projects newly built, expanded and reconstructed must be tested for indoor environmental pollution. Otherwise, project delivery and acceptance cannot be carried out. In this way, on the one hand, it is the restriction on businesses and enterprises that provide consumers with housing, furniture, and interior decoration services. At the same time, once the indoor environment pollution occurs, it can effectively protect the legitimate rights and interests of consumers.
