With growing awareness of environmental protection, consumers are increasingly concerned about the environmental performance of home decoration materials. In recent years, many traditional decorative materials have been criticized as major contributors to indoor air pollution due to excessive levels of formaldehyde, benzene, TVOCs (total volatile organic compounds), and other harmful substances. To better understand what makes a decorative material environmentally friendly, this article will provide a detailed analysis of harmful substances in decoration materials, the reasons for their excess levels, and explore the standards for environmentally friendly materials, as well as examples of materials that meet these standards.
Harmful Substances in Decorative Materials and the Reasons for Their Excess Levels
Decorative materials, during production and use, may release harmful substances, with the most common being formaldehyde, benzene, TVOCs, etc. These substances can seriously impact human health, especially with prolonged exposure, potentially causing respiratory diseases, skin allergies, dizziness, and even cancer. Below are some common harmful substances and the reasons for their excess levels:
1.Formaldehyde
Formaldehyde is a common harmful gas found in many decorative materials, especially in wood-based products like plywood and particleboard. The primary source of formaldehyde release comes from the adhesives and binders used in production. Formaldehyde is a carcinogen classified by the International Agency for Research on Cancer (IARC), and long-term exposure can cause respiratory issues, allergic reactions, and even cancer.
Reasons for Excess Levels:
Many decorative materials, such as MDF (Medium Density Fiberboard), particleboard, and plywood, use adhesives that contain high levels of formaldehyde. Manufacturers may use lower-cost adhesives with higher formaldehyde release to cut costs, leading to significant emissions of formaldehyde during use.
2.Benzene and Toluene
Benzene and toluene are organic solvents commonly found in paints, coatings, and adhesives. These compounds evaporate during application and construction, and prolonged exposure may cause headaches, drowsiness, memory loss, and even increase the risk of cancer.
Reasons for Excess Levels:
Some low-quality paints and coatings may contain high levels of benzene and toluene, especially cheaper products where non-compliant raw materials are used during production.
3.TVOCs (Total Volatile Organic Compounds)
TVOCs are a group of volatile organic compounds, including benzene, toluene, and xylene. These compounds are commonly found in paints, varnishes, coatings, adhesives, and other materials. TVOCs vaporize into the indoor air and may cause eye, nose, and throat irritation. Prolonged exposure can lead to nervous system and immune system diseases.
Reasons for Excess Levels:
TVOC excess typically occurs due to the use of low-quality paints, coatings, and adhesives. Manufacturers may use non-compliant solvents or raw materials with high concentrations of volatile organic compounds to reduce costs.
4.Asbestos
Asbestos was once widely used in construction materials, particularly for fireproofing, insulation, and soundproofing. However, prolonged exposure to asbestos dust can lead to lung cancer, asbestosis, and other serious diseases, leading to its ban in many countries.
Reasons for Excess Levels:
Some inferior or outdated construction materials may still contain asbestos. Due to its hazardous nature, the presence of asbestos must be strictly controlled in construction and decoration materials.
5.Ammonia
Ammonia is present in certain decorative materials, especially wood-based products, and can irritate the respiratory system and skin. It can also cause discomfort for individuals with allergies. The presence of ammonia is typically a result of chemical reactions in untreated wood or the use of chemical additives.
Reasons for Excess Levels:
The use of untreated wood or additives containing ammonia in the production process can lead to ammonia emissions.
Standards for Choosing Environmentally Friendly Decorative Materials
To determine whether a decorative material is environmentally friendly, we need to consider several key standards:
1.Formaldehyde Emission Levels
Environmentally friendly materials should comply with national or international environmental standards for formaldehyde emission levels. For instance, wood products that meet E0, E1, or E2 standards should release formaldehyde at or below the permissible levels specified by regulations.
2.Low VOC Emissions
Low VOC (volatile organic compounds) emission materials help reduce the concentration of harmful gases in indoor air, maintaining air quality. Modern environmentally friendly materials should use raw materials with low or zero VOC content, thus minimizing harmful emissions.
3.Free from Harmful Chemical Additives
Environmentally friendly decorative materials should avoid the use of harmful chemicals such as benzene, toluene, formaldehyde, ammonia, etc. Moreover, the materials should not contain solvents or additives that are hazardous to human health.
4.Recyclability and Renewability
Environmentally friendly materials should be highly recyclable and renewable. The production and usage processes should minimize environmental impact, and waste materials should be recyclable and reusable.
5.Durability and Pollution Resistance
Environmentally friendly materials should be durable and resistant to pollution, reducing the need for frequent replacement and repairs. This helps reduce resource waste and environmental burden.
Examples of Environmentally Friendly Decorative Materials
Below are some examples of decorative materials that meet environmental standards. These materials not only reduce the use of harmful substances during production but also ensure low emissions of harmful substances during use.
