Just after the white dew's solar terms last week, it means that the weather is starting to cool down, but like Beijing and Shanghai, the highest temperature is still in the '3' prefix. Many families waiting for the autumn to start renovations can't wait to start work. When the autumn tiger has not left, the renovation of the new house or the renovation of the old house, then prevention of formaldehyde pollution will become a top priority.
Why does the decoration necessarily produce formaldehyde?
As we all know, the decoration will produce a lot of formaldehyde, and the high temperature, strong sunshine will increase the emission of formaldehyde from the plate, accelerate the frequency of formaldehyde emission, resulting in more serious pollution than other seasons.
First of all, you need to know why formaldehyde is 'sacred' and it is easy to smell. Formaldehyde is a highly irritating gas. It is a volatile organic compound. Its effects on human health are irritating to the eyes and respiratory tract, causing the lungs. Liver, abnormal immune function.
The harm caused by formaldehyde is closely related to its concentration in the air. When formaldehyde reaches 0.1mg/m3, it will have odor and discomfort; when it reaches 0.5mg/m3, it will irritate the eyes and cause tearing; reaching 0.6mg/m3, it can cause throat Discomfort or pain. High concentration, which may endanger life safety.
As for the source of formaldehyde, some research indicates that formaldehyde in indoor air mainly comes from indoor decorative materials such as artificial panels. 80% of the decoration materials on the market contain a large amount of organic harmful substances. Once these materials enter the room, they are in a ventilated environment. In a bad environment, the concentration will be high, which will endanger people's health. Among them, the blockboard used for interior decoration, plywood, medium density fiberboard and particleboard all contain formaldehyde.
Since formaldehyde is located in the deep layer of the artificial board rather than on the surface, the release of formaldehyde is a slow, continuous, uninterrupted process. Director of the Beijing Indoor Air Quality Key Laboratory, Zhang Yiping, director of the Building Environmental Testing Center of Tsinghua University, once said: 'After more than a decade, the situation that formaldehyde is still not volatile is very common.'
Solving formaldehyde pollution requires a two-pronged approach
To prevent formaldehyde pollution, it is necessary to eliminate or reduce the production of formaldehyde from the source. It is also necessary to eliminate the existing formaldehyde through the later methods and means, and the two-pronged approach can cure the standard.
How to control formaldehyde pollution from the source, the key is to avoid the introduction of pollution sources, control the materials that can bring formaldehyde to the environment into the room. In the interior decoration and decoration should use the low formaldehyde content decoration, decoration materials, selection in line with national standards, high quality Health and environmental protection building materials. Government departments at all levels should also force the elimination of outdated products and processes in due course.
Nowadays, many developed countries in the world use formaldehyde-based civil chemical products to be baked in special ovens and exhausted formaldehyde outside the oven with a blower to promote the full release of formaldehyde before it is put into the market. With these conditions, the current prevention of formaldehyde pollution can be based on the characteristics of the relationship between formaldehyde and microclimate, the choice of air purifiers and other products for artificial discharge, which is the method of later management.
Of course, there are more than one kind of post-treatment methods, such as window ventilation, such as activated carbon adsorption, etc. There are also some widely used remedies for a wide range of people, such as plant adsorption methods. Are these really reliable? Deputy Chief Engineer of China Household Electric Appliance Research Institute Lu Jianguo, director of the Institute of Testing Technology, first blamed the aldehyde removal effect of green plants: 'I have not seen reports on the absorption of chemicals by plants, some plants that are labeled as 'Shencao', and Does not have the ability to remove formaldehyde. 'And activated carbon can really absorb formaldehyde, but the effect is not immediate.
In terms of effect and input-output ratio, air purifiers have become the most effective and efficient means of removing formaldehyde at the moment. For families in the renovation stage, buying one or more air purifiers is far more exhausting. Try to try a variety of 'singular tricks' with unclear effects.
At present, people's awareness of air purifiers is also improving, but there are many types of air purifiers, each with different functions, some are for particulate matter, some are for benzene, some are for formaldehyde, and where are indoor decoration pollution? 1. Consumers need to select the air purifier with corresponding purification function.
As the leading brand of healthy home appliances, Philips' 5000 series air purifier AC5656 is called formaldehyde trapper, which can reduce the indoor formaldehyde content to 0.01mg/m3. The actual effective application area can reach 42~72m2, for families with general area. Say enough to completely purify your home air.
The new national standard measures the formaldehyde CCM (cumulative purification) value and formaldehyde CADR (clean air output) value of the air purifier in addition to formaldehyde. The formaldehyde CCM value of the Philips 5000 series air purifier AC5656 is the highest P4 grade, the actual value. Breaking through the highest standard of the new national standard, it ensures that the formaldehyde filter is less saturated and the filter has a longer service life. The formaldehyde CADR value is up to 300 m3/h, and the formaldehyde concentration can be reduced to 0.01 mg/m3 in 28 minutes.
At the same time, the nano-scale filter mesh is equipped with an ultra-wide contact area. The built-in coconut shell activated carbon has stronger adsorption capacity than ordinary activated carbon. The special porous substrate is combined with the aldehyde-removing formula to actively capture and remove formaldehyde molecules.
The Philips 5000 Series Air Purifier AC5656 also features cutting-edge Vitashield IPS micro-shield purification technology, which has been proven to remove ultra-fine particles of at least 0.003 micron (800 times smaller than PM2.5), allowing you to keep all kinds of contaminants out of your home. It can filter including PM2.5, pollen, dust, animal dander and viruses, bacteria such as H1N1, EV71 (HFMD), etc. It is also certified by ECARF (European Allergy Research Foundation) for the purification of allergens. Both clean air and a healthy home environment have a comprehensive care for the respiratory health of you and your family.
The Philips 5000 Series Air Purifier AC5656 is equipped with AeraSense Inductive Technology, which can detect particles, harmful gases and allergens in real time through four-color LED lights, and provide timely feedback on the body to keep the air in your home. At a glance, to achieve the true 'visible' peace of mind.
Renovating the house is undoubtedly a happy thing, but with the autumn tiger decoration, you should pay special attention to the protection of formaldehyde. Even after ventilation, the continuous formaldehyde volatilization still needs to be equipped with one or more air purifiers. The family is not affected by formaldehyde pollution.
