It is understood that, according to the national "indoor air quality" and "civil building indoor environmental pollution control norms," ​​the formaldehyde emission per cubic meter of indoor air shall not exceed 0.1 and 0.08 mg standard. The results of the spot inspection conducted by the China Indoor Decoration Association's Indoor Environmental Monitoring Working Committee in 2004 in a newly renovated family of 1000 households in Beijing showed that formaldehyde exceeded 60%. Judging from the inspection data of relevant departments in Qingdao, Nanjing, Yinchuan, Chongqing, Shenzhen, and Urumqi in other regions, the unqualified rate of formaldehyde in newly-renovated homes is above 60%. Shenzhen Metrology and Quality Inspection Institute 1 to 7 In the month, a total of more than 400 houses in the city were tested for indoor environments, and 90% of formaldehyde exceeded the standard. Newly renovated room

Four sources of formaldehyde

Director Song Guangsheng said that the main sources of formaldehyde in households: First, from the artificial plates used for interior decoration such as plywood, blockboard, medium density fiberboard and particle board. The second is from indoor furniture. Including wood-based panel furniture, fabric furniture, kitchen furniture. Third, it comes from other types of decorative materials containing formaldehyde, especially unqualified white latex and paints. Fourth, from the interior decoration textiles, including bedding, wall coverings, wallpapers, carpets and curtains.

Three links to control formaldehyde pollution

Song Guangsheng reminded consumers that the formaldehyde pollution caused by the decoration should be prevented in three links: First, the interior and exterior elements should be taken into consideration in the decoration and decoration design, and the decoration materials should be properly matched to fully take into account the carrying capacity and ventilation of the indoor space. Secondly, in the construction process of interior decoration, it is necessary to use non-toxic, less toxic, non-polluting and less polluting construction techniques. The use of the sawn cut of the artificial board should be coated with paint to fully cure it, which can form a stable Protective layer to prevent the formaldehyde emission inside the sheet. Thirdly, we must select qualified interior decoration materials in strict accordance with national standards. At present, the state has formulated ten mandatory standards for “restrictions on hazardous materials for interior decoration and decoration materials”. Consumers must choose to comply with national standards for pollution-free or decoration when they decorate and decorate. Less polluted product.

N ways of formaldehyde treatment

For the house that has produced formaldehyde pollution, Director Song Guangsheng proposed the following treatment plan: If a product such as formaldehyde elimination agent is used, it is better to use it in the decoration project, which can effectively reduce the free formaldehyde in the wood-based panel. You can also choose air purifiers that have a certain adsorption effect on indoor pollutants such as formaldehyde. At the same time, plants can be used for purification. For example, planting plants such as spider plants, aloe vera, and green radish indoors can also reduce indoor formaldehyde concentrations. Home Decoration Prevent Ten Indoor Misconceptions

Industry experts have reminded consumers to keep their eyes open. According to reports, disputes over home furnishings have become hot spots for complaints. Some home improvement companies make use of the characteristics that people are trusting and unfamiliar with the format contract and set a "trap" in advance. Mainly in:

Confusing material general quote

At the time of signing, some home improvement companies calculated the general quotation of a certain material, but changed the individual materials during construction. Therefore, the brand, model, color, and price of the material must be clearly stated in the contract.

Terms are not self explanatory

Some home improvement companies concoct some terms that are not specific or ambiguous. Once a dispute arises, it will be helpful to interpret and reduce the liability for avoidance. If a consumer reports that the use of a certain brand of paint is stipulated in the home improvement contract, the quality of the paint is found to be poor after renovation. The home improvement company argued that although the contract stipulated the paint brand, it did not agree on the grade of the brand paint.

Underreport budget deception contract

Some decoration companies understated their budgets and intentionally concealed or underreported the amount of work during the design of the renovation project, making consumers feel that they are cheap and happy signing contracts. When the settlement is made on a real basis, consumers are found to be fooled and greatly overspend.

Change the materials to earn the difference

The contract stipulates that high-grade decorative materials are actually used but low-priced ordinary materials. After being disguised, it is difficult to be found.

Material quality of the same name

Some home improvement companies deliberately buried inferior “good fortune” when signing contracts. For example, “If the original brand material in the decoration is out of stock, Party B? Point decoration company? Snow can temporarily replace the same type of material”.

Confusion concept more than the cost <br><br><br><br><br><br Experts suggest that signing a contract requires four principles: First, the specific requirements for the decoration and the completion date must be specified in the contract; secondly, the specific brand or model of the decorative material must be specified in the contract to prevent the decoration company from Thirdly, during the project, if consumers increase or decrease the number of renovation projects, they must fill out the relevant "engineering change orders", as an annex to the contract, into the decoration contract; Fourth, the contract The warranty provisions should be complete and the responsibilities should be clear.
