One: There are standards for decoration and environmental protection?

There are standards for decoration and environmental protection. The Ministry of Construction promulgated the "Regulations on Indoor Environmental Pollution Control for Civil Construction Projects" (GB50352-2001). The State Administration of Quality Supervision, Inspection and Quarantine issued the "National Standard for the Limits of Indoor Decorations and Harmful Substances". These are the basis for the environmental protection in the decoration.

II: What does it mean to say "indoor decoration pollution"?

Usually refers to the materials used in interior decoration and decoration to emit harmful toxic pollutants and pollute the indoor environment. This indoor pollution from the decoration itself is called "interior decoration pollution." If the content of contaminants in homes is too high, and if it is not resolved for a long time, it will cause discomfort to people, affect health, and even cause serious illness.

Three: What are the major pollutants in home improvement?

According to the use of construction, decoration and decorative materials in China, indoor decoration pollutants mainly include the following types: formaldehyde; benzene series (such as: benzene, toluene, xylene); total volatile organics (TVOC); free toluene diisocyanate (TDI); Soluble lead, cadmium, mercury, arsenic and other heavy metals.

Four: In the decoration, the pollutant is the root cause of the disease?

Decoration pollution can cause people to be sick, but there are many reasons for people to develop diseases. If the decoration pollutants are too high in the newly renovated premises and they cannot meet the national environmental protection standards and will not be solved in the long term, it will obviously affect their health. However, experts pointed out that there is still no scientific evidence that a certain disease is caused by indoor air pollution. Therefore, prevention of excessive air pollution is more important and effective than accountability after the fact.

V: What is the problem of the false environmental protection and conceptual environmental protection?

The fundamentals of false environmental protection and concept environmental protection are fraudulent acts of unfair competition in the market competition, irresponsible behaviors against the integrity of consumers and enterprises themselves, and should be resisted by the industry and consumers. The condemnation of public opinion. To achieve true environmental protection decoration, only by starting with the most basic materials, ensure that all decorative materials meet the national environmental protection standards (or higher environmental standards), and construction in strict accordance with the environmental protection construction standards, is the fundamental way to solve.

VI: What materials are the main sources of indoor decoration pollution?

(1) Formaldehyde mainly comes from man-made materials, adhesives and coatings

(2) Benzene series mainly comes from paint thinner, waterproof coating, emulsion paint, etc.

(3) Total volatile organic compounds contained in (TVOC) are mainly derived from paints, latex paints, etc.

(4) (TDI) toluene diisocyanate mainly derived from polyurethane coatings

(5) Heavy metal pollution materials mainly come from paints, adhesives, etc.

Seven: Is it safe to use a decorative material that has just reached the mark?

People usually think that using all the testing materials that meet the standards is equal to the standard and it is not. For a decoration material that has just reached the standard, if the amount of the above-mentioned decorative materials containing home-use contaminants is excessive within a certain unit area, it will also cause excessive pollutants. Therefore, only by using a higher standard of environmental protection decoration materials can indoor pollution be avoided. Accumulated items exceeded.

Eight: How to ensure that the decoration meets the requirements of environmental protection?

First of all, environmental protection materials are fundamental. As the harmful substances in the indoor air are mainly released from the decoration materials, there is no environmental protection for the materials and there is no environmental protection after the decoration. Second, environmental design training is the key. With environmental protection decoration materials, there is not necessarily environmental air quality, because the release of harmful substances has a "superimposed effect." Through the training of designers in this area, designers have mastered "theory of pre-assessment of air quality" and changed post-event control of environmental protection decoration into prior control. Third, environmental protection construction is very important. With scientific and rational environmental protection design and environmental protection materials, there must also be environmental protection construction. Because the non-standard and non-standard construction has a crucial influence on the air quality after the renovation, such as not sealing the inside and outside of the wood products, the outer edges do not close the mouth, and the ventilation and ventilation are not maintained in the construction. Can cause or aggravate air pollution. Therefore, the training of the director of engineering and construction team leader, and the careful implementation of relevant national policies and regulations are another important guarantee for environmental protection renovation.

Nine: Where are the sources of decoration pollution, and what are the solutions to poisoning?

(1) The main sources of indoor pollution sources are: Aldehydes - mainly from plates and binders; Benzene, xylene - mainly from paints; Phosphorus, mercury - mainly from interior paints.

(B) related recommendations:

Try to avoid the use of large core boards such as plywood with high glue content, use trimeramine trim panels; try to avoid paint production at the scene, use paint-free technology; use environmentally-friendly materials to reduce the emission of harmful gases; try to use environmentally friendly trimeramine plates as the basis. Material, due to the more stable physical and chemical properties of triamine, it is not easy to produce deformation. In addition, the trimeramine trim panel does not require finishing treatment such as later painting, and also reduces the possibility of surface cracking.

In addition, do a good job of comprehensive planning before the renovation, determine the style and style of good furniture to ensure the smooth progress of home improvement projects.
