What are green building materials?
Green building materials are also called ecological building materials, environmental protection building materials and healthy building materials. Green building materials refer to the use of clean and hygienic production technology, less natural resources and energy, a large number of industrial or urban solid waste, non-toxic, pollution-free, non-radioactive, conducive to environmental protection and human health.
What environmental protection materials are there?
1, basically non-toxic and harmless. It refers to natural decorative materials with no or little toxic substances, only simple processing and no pollution. Such as gypsum, talcum powder, sandstone, wood and some natural stones.
2. Low toxicity and low emission. Refers to the decorative materials that control the accumulation and slow release of toxic and harmful substances through processing, synthesis and other technical means. Because of their slight toxicity, they do not pose a danger to human health. Such as large core board, plywood and fiberboard with low formaldehyde emission and meeting national standards.
3, the current science and technology and detection methods can not determine and evaluate the materials affected by toxic substances. Such as environmental protection latex paint, environmental protection paint and other chemical synthetic materials. These materials are harmless at present, but with the development of science and technology, there may be new identification in the future.
What are green building materials?
1. Green building materials: Grass-planted pavement brick is one of various porous paving products, made of recycled high-density polyethylene. It can reduce storm runoff, reduce surface pollution and discharge surface water. Used for public facilities.
2. Green wall material: The newly developed aerated concrete block can be cut and shaped with woodworking tools, built with a thin layer of mortar and covered with special mortar powder, which has the effect of heat resistance and energy storage.
3. Green wall decoration: grass wallpaper, hemp wallpaper, gauze thick-walled cloth and other products, with moisturizing, insect repellent, health care and other functions. Mildew-proof wallpaper is chemically treated to eliminate mildew, foaming and mildew when the air is humid or the indoor and outdoor temperature is high. Moreover, the surface is soft and breathable, the color is natural, and it has the effect of oil painting, revealing a quaint and elegant artistic atmosphere.
4. Green pipeline: Plastic-metal composite pipe is a high-tech product to replace metal pipe. Its inner and outer layers are made of high-density polyethylene material, with aluminum in the middle, which has excellent properties of plastic and metal, no rust and no pollution.
What kinds of environmental protection materials and green decorative materials are there?
5, green paint: biological latex paint, in addition to simple construction, there are various colors, which can bring colorful colors to the home. After brushing, it will give off fragrance, and it can also be cleaned or treated with detergent, which can inhibit mold in the wall.
6. Green carpet: a new type of environmentally-friendly carpet, which has many functions such as anti-corrosion, moth-proofing, anti-static and flame retardant. There is "anti-block craft carpet" on the style, which can be spliced at will according to the block pattern.
7. Green lighting: This is a lighting system aimed at saving electricity and protecting the environment. Create a comfortable, economical and beneficial lighting environment through scientific lighting design and the use of efficient, safe and high-quality lighting electrical products.
Identification of green building materials products
First, the most intuitive way is to check the environmental protection signs in China. Its figure consists of green hills, green waters, the sun and ten rings around it. The central structure of the figure represents the environment on which human beings depend, and the ten outer rings are closely combined and connected, indicating public participation and environmental protection; At the same time, the word "ring" in ten ring is the same as the word "ring" in the environment, which means "the whole people are connected and * * * protects the environment on which human beings depend".
Second, "looking, smelling, asking and cutting" identification materials.
Look, just look at the appearance, see if the instructions indicate the ingredients and whether they contain toxic substances;
Second, smell, that is, smell, smell whether it is irritating;
Three questions, that is, ask whether its products have been tested by relevant authorities and whether they are safe;
Four cuts, that is, touch it with your hands, touch it, whether there is a burning sensation, and whether there is erythema in the touched part.
