Nowadays, people's living standards have been continuously improved, and indoor decoration has become more and more luxurious. But have you ever thought that more and more decoration materials will lead to increased pollution. Decoration pollution is seriously endangering people's health, which is called “ Invisible killer ”, According to statistics, more than 68% of people's diseases are related to indoor pollution

decoration pollution refers to the pollution caused by the release of harmful substances contained in decoration materials and furniture into the home and office environment. Paint, particleboard, paint and other decoration materials and furniture mostly contain toxic and harmful substances. China's "code for indoor environmental pollution control of civil construction engineering" lists five main pollutants: formaldehyde, benzene, ammonia, volatile organic compounds (TVOC), radioactive radon

some survey data fully illustrate the current universality of decoration pollution. In August, 2002, relevant institutions in Shanghai conducted three surveys on formaldehyde, benzene and TVOC of 26 newly decorated houses, and only 8% of the houses met the requirements of GB50325-2001. However, the qualified rate of formaldehyde concentration of 10 households whose occupancy time is more than 3 years is only 10%

many consumers question why all the materials purchased are qualified products, but the pollution will exceed the standard? This is because of pollution “ Superposition effect ”. Environmental protection products or qualified products are not free of pollution, but the content of pollutants is low. For example, furniture, the formaldehyde content of E2 grade is less than or equal to 5 mg/L, and that of E1 grade is less than or equal to 1.5 mg/L. now only a few products can reach E1 grade

in decoration, the area of walls and ceilings is the largest, and their surface materials have a great impact on the degree of decoration pollution. Even the water-based paint emulsion paint with good environmental protection performance also contains high VOC and formaldehyde. GB18582-2001<& lt; Limit of harmful substances in interior wall paint of interior decoration materials >& gt; It is stipulated in the regulations that the volatile organic compounds (VOC) in the interior wall paint shall not exceed 200g/l, and the free formaldehyde shall not exceed 0.1g/kg. However, if the pollution released by a variety of decoration materials is superimposed, it will form a superimposed effect of pollution, which will also lead to the pollution of new houses exceeding the standard. Even after three months of decoration, many houses still have a strong smell and cannot be occupied at all. Therefore, consumers urgently need a truly healthy coating

in 2011, the output of architectural coatings in China was more than 4 million tons. According to the medium-range level of 75 g/L VOC emitted by water-based coatings into the atmosphere, about 300000 tons of VOC are emitted into the atmosphere every year, but the VOC emission of solvent-based coatings has not been calculated (the VOC emission of solvent-based coatings is much higher than that of water-based coatings, which generally produces 500 g/L). The pollution of coatings to the atmosphere is second only to automobile exhaust. Coatings are an important source of VOC in the atmosphere and an important cause of greenhouse effect

in recent years, although many paint manufacturers have been playing the environmental protection brand, from “ Green ” To water, then to “ Low carbon ”, However, there are no substantial changes in the selection of raw materials, technical formulas, VOC emissions and functions, and the conceptual hype is greater than the actual effect

green and environmental protection are not just a concept, but a way of life that human beings must choose. In the process of paint manufacturing, we should first try to reduce the use of precious oil resources. Secondly, we should try to reduce the emissions of pollutants, especially VOC emissions. Finally, in the process of consumption, we should guide the public to correct those habitual consumption patterns and lifestyles that waste energy and increase emissions of pollution, so as to give full play to the great potential of energy conservation and emission reduction in the field of coating product consumption

the promotion of diatom mud and other inorganic dry powder coatings can save millions of tons of oil resources and reduce VOC emissions by hundreds of thousands of tons every year. This is an important link in the field of energy conservation and emission reduction and a major event beneficial to the country and the people. Its significance is no less than the leap from ordinary fuel vehicles to electric vehicles. I hope the government will give some policy support
