Nowadays, the household building materials industry, such as the wardrobe, is being tested by a new round of market in the increasingly heated topic of environmental protection and health. At the PM2.5 sub forum of the 2013 annual meeting of the Guiyang International Forum on ecological civilization held recently, experts from the Chinese Academy of engineering, the Chinese Academy of Environmental Sciences and other experts said that China has become the region with the most serious PM2.5 pollution in the world. But in fact, the pollution caused by indoor decoration is far more serious than outdoor pollution such as PM2.5

nowadays, in the household building materials industry such as wardrobe, where the topic of environmental protection and health is increasingly heated, it is being tested by a new round of market. At the PM2.5 sub forum of the 2013 annual meeting of the Guiyang International Forum on ecological civilization held recently, experts from the Chinese Academy of engineering, the Chinese Academy of Environmental Sciences and other experts said that China has become the region with the most serious PM2.5 pollution in the world. But in fact, the pollution caused by indoor decoration is far more serious than outdoor pollution such as PM2.5

in May last year, according to the survey and statistics of the environmental testing center of the China Interior Decoration Association, the number of deaths caused by indoor air pollution in China reached 111000 every year, with an average of about 304 deaths per day, equivalent to the number of deaths caused by car accidents in the country every day. In fact, indoor air pollution is often 2-3 times more serious than outdoor air pollution, and in some cases, it can even reach more than 100 times. About 300 kinds of pollutants can be detected indoors, and 68% of human diseases are related to indoor air pollution. These pollutants mainly come from activities such as building decoration

Zhou Chunliang, head of the indoor air and decorative materials monitoring department of Hunan CDC, analyzed that at present, the main sources of indoor air pollution are indoor decorative materials and furniture. Paint, plywood, particleboard, foam filler, interior wall coating, plastic veneer, adhesive and other materials contain Organic volatiles such as formaldehyde, benzene, ammonia, toluene and so on. These organic volatiles will release a large number of toxic gases, which are released continuously. The continuous volatilization cycle of formaldehyde generally lasts for 3 to 8 years. The carcinogenic effect of formaldehyde mainly depends on its concentration. High concentration formaldehyde is toxic to the nervous system, immune system, liver, etc., and has teratogenic and carcinogenic effects

then why are formaldehyde, benzene and other pollutants exceeding the standard repeatedly banned in the industry? The main reason is that most of China's building materials market is occupied by some small enterprises, and small enterprises have weak control ability in product standards such as raw materials and finished product inspection for the purpose of reducing costs, so that a large number of unqualified decoration materials fill the market, resulting in decoration pollution. In addition, there are certain loopholes in the testing process of relevant departments in China, which is also one of the reasons for enterprises to take risks. A staff member of the Beijing Municipal Bureau of quality and Technical Supervision said that a large number of unqualified products have entered the market, which is seriously related to the local protection ideology of the local government. Many unqualified building materials have entered the market under the eyes of the regulatory authorities

a survey shows that 80% of the surveyed owners only pay attention to the purchase of main materials, and auxiliary materials are often purchased by decoration companies themselves. Decoration companies know more about the building materials market. Although they know what materials meet environmental protection standards, they often choose materials based on profits, so they try to buy cheap and unqualified auxiliary materials. Although the owner agreed with the decoration company on the brand and model of the main materials when signing the contract, the standards were reduced to varying degrees in the procurement. Finally, indoor pollution exceeded the standard

as the indoor environment has attracted more and more attention, after home decoration, some owners who advocate rights protection will also find relevant institutions to test the indoor air quality. However, some unqualified non-governmental environmental testing centers took the opportunity to make money and make reports in order to fool the owners. For example, there are two kinds of indoor testing, namely, basic testing and authoritative testing. Most testing companies without testing qualifications and equipment can only carry out basic testing, but issued the so-called “ Authoritative report ”. To a certain extent, this erroneously guided people's judgment on the quality of decoration. Living in a house full of formaldehyde, they thought they were very healthy

through efforts, China's indoor air quality standard system has basically taken shape. However, in the process of formulating IAQ standards, there is a lack of certain basic data, which is mainly reflected in: the release amount of harmful substances in buildings, decoration materials, release years, and the relationship between them and other parameters; Basic toxicological data of pollutants, large-scale investigation of pollution status, content of harmful substances in products and process level, etc. At present, there is no relevant standard specially formulated for residential ventilation in China. Only the basic requirements related to ventilation, such as the minimum area of doors and windows and the setting of vertical air ducts in kitchens and toilets that can be connected with local exhaust devices, are included in the code for design of residential buildings (gb50096-1999). Therefore, from architectural design, ventilation product development to residents' reasonable organization of room ventilation, there is a lack of specific guidance

as a “ The last piece of cake ”, The wardrobe industry should also be improved in time to integrate with the ecological environment construction as much as possible and become a real industry “ Cake &rdquo
