The selection of coatings for Olympic projects follows three principles

the relevant person in charge of the Beijing Building Materials Industry Management Office introduced at the 2002 coating industry work conference that in the construction of the 2008 Beijing Olympic Games, the selection of coatings will be strict. On the other hand, it can be used as one of the reference data for the running speed of active packaging machinery, tension conditioning, film running wear and tear. It can abide by the three basic principles of "green, science and technology, humanities"

green principle - the limit of harmful substances in interior wall paint should meet the national standard. Only after knowing each part (gb18582-2001): VOC (g/L) ≤ 200; Free formaldehyde (g/kg) ≤ 0.1; Heavy metal soluble lead (mg/kg) ≤ 90; Heavy metal soluble cadmium (mg/kg) ≤ 75; Heavy metal soluble chromium (mg/kg) ≤ 60; Heavy metal soluble mercury (mg/kg) ≤ 60. Strictly regulate the operation from raw materials to employees. The exterior wall coating shall have the functions of low toxicity, mildew resistance, safety and environmental protection

principle of science and technology -- Beijing is an inland city with less rainfall and heavy sandstorms. Therefore, the requirements for exterior wall coatings should not only meet the technical requirements and service life requirements, but also have high stain resistance, high color retention, and weather resistance should be maintained for more than 15 years. In addition, more than 90% of the Olympic venues are steel structures, which puts forward higher requirements for coatings in terms of corrosion prevention, rust prevention, fire prevention, waterproof, antibacterial and thermal insulation

humanistic principle - in the next few years, Beijing will restore some ancient buildings, and renovate some historic sites and paint their facades. At the same time, considering the cultural landscape of Beijing, we should also carry out landscape design for the external facade of buildings, some roads, passages, parking lots, etc., and use the color of paint to realize the effect extension of landscape design. The meter is connected to the expander, and the expander is connected to the experimental machine to measure the deformation results
