environmental protection materials industry Re Lyon Mobile Internet efforts to open up markets

1990s, sustainable development become the choice of many countries. In this context, the green building concept has been widely accepted. With environmentally friendly products gradually become the protagonist in the market, consumers of building materials made safe, healthy, low-carbon requirements. Promote the use of green technology, the use of pollution-free, non-polluting, non-radioactive environment-friendly building materials, the construction industry is the inevitable trend of development.

  Pollution Causes traditional building materials produced
With the continuous improvement of living standards, people are more and more attention to the built environment. However, some traditional building materials by chemical material, containing toxic substances. Such materials continue to release toxic gases into the room, harmful to human health. According to media reports, the US Environmental Protection Agency experts have for 10 new housing for sampling. Test results showed that the indoor air in buildings more than 500 kinds of chemical substances, many times higher than outdoor.
The results showed that 2% to 3% of the house has asbestos and radon, about 10% of the house there are viruses, bacteria and other microorganisms. Interior with these harmful substances in buildings called "sick building." These "sick" building will own "disease" spread to the house user. It turns out that the poor quality of building materials release harmful substances to human health is very negative. Building closed higher temperature, providing a favorable environment for bacteria breeding, greater harm to human body.
Application of environmentally friendly building materials
For a long time, we have always thought that China is a country of vast land that the Chinese people have the natural resources are very rich. In fact, per capita natural resources of our country is far below the world average. How to get more Chinese entrepreneurs and ordinary residents recognize the importance of energy conservation, everyone is worth thinking about.
Development of environmentally friendly construction materials
Green building is the building of efficient use of resources, namely energy conservation, environmental protection, comfortable and healthy building. Choose green building materials should follow the following two principles: one is to make use of 3R (Reduce, Reuse, Recycle, can be reused, can be recycled, the use of renewable) material; the other is the choice of non-toxic, harmless, not pollute the environment, human health materials and products, preferably with the State environmental Protection logo materials and products.
Compared with the traditional building materials, new building materials can not only reduce energy consumption, but also the rational use of industrial waste. New building will not only pollute the indoor environment, but also beneficial to human health, help to improve the built environment can play a mold, noise insulation, sterilization, temperature control, humidity control, dimming, flame retardant, deodorant effect. New environmentally friendly building materials production process does not pollute the environment, does not generate new waste, and most can be recycled.
From our market situation, most companies do not know their production or sale of building materials compliance with national standards, not to mention accordance with national standards of production or sales of building materials.
Modern social and economic development, infrastructure and housing construction scale is growing. Mass production and use of building materials to improve the human living environment provides material security, but also paid excessive energy consumption and serious environmental pollution and other costs. Therefore, in order to protect the environment and achieve sustainable building design, raw materials must be included in the environmental impact of the standards system to measure the value of the building. Building is derived from nature and return to nature, the use of materials should not cause harm to humans and the surrounding environment. In clay brick for example, the production process would damage the soil environment.
From the perspective of sustainable development, the use of wood should be more prudent in the building. Cut down trees can cause a series of problems, such as increase in transportation energy, environmental and economic damage to the local ecological environment. Environment-friendly building should have superior durability, easy maintenance and management, with little or no release of release of hazardous substances. To achieve the goals of sustainable development, the negative impact of building materials on the environment is minimized, and the technology required to develop pollution-free construction of environmentally friendly building materials. For example, the use of industrial waste (fly ash, slag, coal gangue, etc.) production of cement, brick and other building materials, the use of waste production and wall insulation foam board, utilizing waste glass production veneer materials. This approach can be used both industrial waste, reduce environmental pollution, but also save natural resources.
Energy saving material future will become the mainstream
Energy saving materials in the construction sector has been widely used in the future will become the mainstream market. It is understood that Europe has set off a wave of architectural revolution. People look forward to future housing will not only achieve energy self-sufficiency, but also the remaining power supply network. This is a new requirement for people to put forward the construction industry.
Use of environmentally friendly building materials for the construction industry into the "fresh blood." Environmentally friendly building materials not only solve the environmental problems of general interest, but also to achieve a rational use of resources and recycling, make the building in the design and construction tends to be more perfect.
Based green building is environmentally friendly materials. By vigorously promote the use of environmentally friendly building materials, use of modern high-tech tools for the design, construction, use pollution-free production technology, construction and sustainable development will gradually become a reality. Green building is in line with the concept of sustainable development in building the human and the natural harmony of the product as a symbol of human civilization. We must consciously protect the living environment, and create a good living environment, to create a harmonious green homes.
