Recently, a company employee died of leukemia, and the event of renting a formaldehyde room during his lifetime was screened on the Internet. This is not the first time that a long-term rental apartment has exposed formaldehyde. The dispute last year has not subsided. A bigger accident. So some people say that the formaldehyde problem has become the original sin of the 'long-term rental apartment'. So the formaldehyde problem really has no solution? How much do you know about formaldehyde?
After the renovation, the formaldehyde will be fatal.
According to the article, Mr. Wang had a comprehensive physical examination when he joined the company in January this year. The physical examination report showed that the physical indicators were normal. After his death, his wife came to Hangzhou to test the house rented by Mr. Wang in Hangzhou. Display: Formaldehyde exceeds the standard. The wife said that when her husband is in Hangzhou, most of the time is summer, hot, air-conditioned, I am afraid it is difficult to open and ventilate.
According to the "Code for Indoor Environmental Pollution Control of Civil Building Engineering", there are five main types of pollutants generated in home decoration: formaldehyde, benzene, ammonia, radioactive cesium, TVOC (total volatile organic compounds). Among them, formaldehyde and benzene are the most Common, the two most harmful types of pollutants.
According to industry sources, in general, apartment operators receive a formaldehyde removal treatment after receiving a project, but they also know that formaldehyde can't rely on a governance to 'destroy'. It is impossible to leave the room empty in the face of interest. Ventilation and ventilation to remove formaldehyde, so a large number of listings are rented out soon after the renovation.
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 abnormalities in the lungs, liver and immune function.
According to the World Health Organization (WHO) survey, indoor air is found to be harmful to health in 30% of new and rebuilt buildings in the world.
The newly renovated house is easy to produce formaldehyde because formaldehyde mainly comes from the glue in the composite wood building materials. The old house that has been in residence for more than ten years does not mean that there is no worry about formaldehyde. The glue in the composite wood building materials is generally used in the deep man-made boards. The place, and the volatilization rate of formaldehyde is slow. After more than ten years, the situation that formaldehyde is still not volatile is very common.
Summer is the high incidence of formaldehyde. There is data showing that for every 1 degree increase in temperature, the concentration of formaldehyde increases by 0.15-0.37 times, the boiling point of formaldehyde is 19 °C, and when the indoor temperature is 30 °C, the release of formaldehyde is the highest, while 20- 30 ° C is the common temperature in summer.
When formaldehyde reaches 0.1mg/m3, it will have odor and discomfort; when it reaches 0.5mg/m3, it can irritate the eyes and cause tearing; reaching 0.6mg/m3, it can cause throat discomfort or pain. High concentration, which may be life-threatening It’s safe.
All kinds of methods go into battle, how to solve the problem of formaldehyde?
So, how to solve indoor formaldehyde pollution? We often hear some small-scale, small-scale demolition of formaldehyde, such as window ventilation, plant adsorption, etc. Are these really reliable?
Tsinghua University School of Environment once conducted an experiment in which aloe vera, green radish, grapefruit peel, dried tea and activated carbon were placed in a 40-liter experimental chamber. The formaldehyde value decreased in the first few minutes, but then it will rise again. Therefore, it does not have the effect of completely removing formaldehyde.
Even if it has certain effects, according to the experimental conditions, it is necessary to place 150 grapefruit peels, 12 kilograms of leftover tea, 31.2 kilograms of activated carbon or 625 pots of small green plants in the home environment of 10 square meters. Obviously it is not Practical.
Formaldehyde is no small matter, empty net should become a must for home
The most authoritative and effective method for removing formaldehyde is to have a qualified professional organization to carry out formaldehyde detection and treatment on the house, but the general cost is more expensive and not convenient. In recent years, with the popularization of air purifiers, many have excellent The empty net product of formaldehyde capacity is welcomed by consumers. Compared with passive green plants that remove formaldehyde, active adsorption air purifiers are obviously more efficient, more effective, and suitable for long-term use.
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 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.
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 harmfulness of formaldehyde has been known all the time, even to the extent of the smell of 'aldehyde'. But because it can't be seen, it is still unknown even in the polluted environment of formaldehyde. In real life, there is almost no zero. The environment of formaldehyde exists, and the event of formaldehyde in the long-term rental apartment undoubtedly sounded the alarm to everyone: Compared with the visible smog, it should be more vigilant against the invisible formaldehyde pollution, except for the air purifier with remarkable effect of 'aldehyde'. Become the standard for every modern family.
