1. What are green building materials?
1. 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.
2. Green building materials refer to functional building materials that have little load on the global environment and are beneficial to human health in raw material selection, product manufacturing, use and waste disposal. Building materials industry is one of the industries that consume a lot of resources, destroy green space and cause serious air pollution. Green building materials is to explore the way to change the serious environmental burden into an industry that has less burden on the earth's environment or even contributed to it.
What are green building materials?
1, environmental protection wall material: the newly developed aerated concrete brick 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.
2, environmental protection wall decoration: grass wallpaper, hemp wallpaper, yarn wallpaper and other products, with moisturizing, insect repellent, health care and other functions. After chemical treatment, the mildew-proof wallpaper eliminates mildew, foaming and mildew when the air is humid or the temperature difference between indoor and outdoor is large, and the surface is soft and breathable.
3, 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.
4. 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.
5, 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.
All of the above are about what green building materials are and what green building materials are. I hope I can help you understand the knowledge about green building materials. Please continue to pay attention to more decoration knowledge, decoration company evaluation and decoration cases.
