Explanation on the environmental protection of building materials used in Hongyuan Building
The Hongyuan Building project of w88 casino has entered the completion acceptance stage. Now we would like to explain the indoor air quality issues that everyone is concerned about as follows:
There are five testing indicators for indoor environmental quality: mainly formaldehyde,TVOC(radioactive), benzene, ammonia, radon, in order to achieveGB50325-2001The "Code for Control of Indoor Environmental Pollution in Civil Construction Projects" Category I requires that all environmentally friendly materials be used in the construction of the Hongyuan Building project and the material entry inspection system is strictly implemented to control material quality from the source.
1.About ammonia pollution: Ammonia mainly exists in concrete. It is due to the use of ammonia-containing admixtures in concrete that causes ammonia to exceed the standard. The Hongyuan Building project uses commercial concrete. It is strictly prohibited to use admixtures containing ammonia in commercial concrete. Commercial concrete must have an inspection report before leaving the factory. Unqualified concrete will not be allowed to leave the factory.
2.About radon pollution: Radon mainly exists in the soil. The Hongyuan Building project had been tested for radon before the start of construction, and the test results were qualified.
3. About formaldehyde pollution: Formaldehyde mainly exists in the chemical binders of decorative materials. The Hongyuan Building uses Tiantan brand solid wood paint-free doors, and the tables, chairs, and beds in the room are all made of steel and wood furniture to avoid paint pollution to the greatest extent.
4. AboutTVOCPollution:TVOC(Radioactivity) mainly exists in stone decorative materials. The floors and corridor walls of Hongyuan Building are all made of tiles, so there is no radioactivity problem.
5. About benzene pollution: benzene mainly exists in chemical materials, the wall selected for Hongyuan BuildingThe top coating is environmentally friendly coating.
According to relevant national and Beijing regulations, the indoor environment must be tested by a nationally recognized building materials testing unit before the project is completed and accepted. Hongyuan Building must also be tested by relevant testing agencies. All projects must be qualified before it can be put into use. Please rest assured.
