What is the price of formaldehyde detection and treatment? Three misunderstandings in in addition to formaldehyde should be clearly understood.
Regarding the necessity of formaldehyde control, first of all, let's talk about the national standard of formaldehyde. In 200 1 year, China issued the code for indoor environmental pollution control of civil construction projects (GB50325-200 1), which defined the limits of indoor environmental pollution concentration of various construction sites. Taking formaldehyde as an example, the limit value of formaldehyde in this specification (version 20 10) is: Class II civil construction projects (office buildings, shops, hotels, cultural and entertainment places, bookstores, libraries, gymnasiums, public transport waiting rooms, barbershops and other civil construction projects) formaldehyde ≤0. 10mg/m3.

1, formaldehyde hazard: Why do people care so much about this problem? Because around us or in the news, we often hear "which child has leukemia because of the new clothes at home" and "Do you know who it is?" What cancer was found a few days ago? It is estimated that formaldehyde exceeded the standard when his home was decorated ... formaldehyde is irritating to people's eyes and upper respiratory mucosa, and its harm to human health is mainly manifested in abnormal sense of smell, allergies, abnormal lung function, abnormal liver function and abnormal immune function. Acute formaldehyde poisoning can cause tears, severe eye pain, itchy throat, cough, dyspnea and suffocation, accompanied by general weakness, sweating and headache; Chronic poisoning can lead to digestive system disorder, excitement, visual impairment and even nerve paralysis.

2. Sources of formaldehyde: There are too many sources of indoor formaldehyde. Besides the well-known wooden furniture, floor and latex paint, there are many things that are easily overlooked, such as curtains, carpets, doors, wallpapers, books, decorations, electronic products and so on. Basically, all the goods you can see at home will release formaldehyde, and not just volatile substances. Take a closer look at the instructions for home appliances. There are also various harmful substances in household appliances. So to put it simply, buying some high-grade decorative materials in order to reduce formaldehyde may not necessarily reduce the overall formaldehyde emission of the whole house. Because maybe the formaldehyde emission of an inferior carpet you bought exceeded the standard. On the contrary, because people attach great importance to these in general decorative materials, there will be no excessive formaldehyde content. Generally speaking, most of your products are produced by regular manufacturers and meet the national quality inspection report standards, but even so, when a large number of products that meet the national standards gather in a relatively closed space and continue to volatilize, the formaldehyde in the house will still exceed the standard. This is why you bought all the products that meet the requirements of environmental protection, but when you enter the house, you will still feel that there is a problem, and it will still exceed the standard if you find a professional testing institution. Here, neither the furniture seller nor the testing agency lied to you.

3. How to deal with formaldehyde: First introduce the release cycle of formaldehyde. Generally speaking, the larger the volatilization area, the faster the volatilization speed; The higher the temperature, the faster the volatilization rate. Then, because most of the decoration materials are ventilated in summer, most of the formaldehyde will evaporate in three months. There are also some cabinets with good edge sealing. Formaldehyde is sealed inside the board, and it is extremely difficult to volatilize into the air, so the volatilization is very slow, which may take 15 years or even longer. But this kind of board is very good, because its volatile concentration is extremely low, so it is basically harmless to people.

4. How to deal with the residual formaldehyde in the room before check-in? The most economical and reliable thing is: open the window for ventilation! And it is ventilated in the case of high temperature in summer! If the temperature is not high enough, the ventilation time should be extended. It is recommended to buy some formaldehyde detection reagents after renovation, which are very cheap, with a few boxes of more than ten yuan, and each room is arranged with detection boxes for testing. Before the test, read the instructions of the test steps in detail, and each step should be carried out in accordance with the guidelines to avoid excessive deviation of the test results. In order to ensure that the test results are true and reliable, wait for two or three days before testing. If the test results of these points are good and close to the national standard value, then there is no problem. If there is no problem in testing again after opening the window for three months, rest assured. If the test results exceed the national standards, it is not too much, and there is not much problem. Open the window for a long time to strengthen air convection. Test once a month until it is lower than the national standard. It usually takes half a year. If it exceeds a lot, it is strongly recommended to ask a professional testing institution to test it, issue a professional testing report, and then find the manufacturer with the testing report. If a claim is made, it should be returned. If it is decorative materials, go to the decoration company. It is difficult to defend rights, or the formaldehyde content is relatively high. What should I do if I don't have time to ventilate and need to live immediately? You can seek the help of professional formaldehyde treatment institutions, and it is more reliable to find professional institutions to deal with it than DIY. For people with high or sensitive quality of life requirements, as well as people with pregnant women at home, it is still recommended to directly find professional testing institutions and governance institutions.

5. How to deal with it after check-in: All the above are the treatment methods before check-in. After staying, we need to keep the air quality for a long time. As mentioned earlier, in some cases, formaldehyde will continue to volatilize for a long time. Although the content is not high, it is still cautious for susceptible people, infants and pregnant women. Because it has been treated by professional testing and treatment institutions before, you can put some activated carbon bags. Although the adsorption treatment method is comprehensive, it will not continue to adsorb formaldehyde, and the adsorbent needs to be replaced frequently (the cost is not low). Secondly, you can buy some chlorophytum, which has a certain absorption effect, but if you want to use chlorophytum to control formaldehyde, it is not enough to use chlorophytum to turn the whole house into a virgin forest, but these plants look good. The other is to buy a professional in addition to formaldehyde filter air purifier. It is recommended to buy energy-saving and environmental protection professional high-efficiency and low-noise air purifier products to keep the air at home for 24 hours. Recently, there is a brand-new product called Kongjing, which is designed and developed by professional filter experts and has a good face value. You can pay attention. You can see it by searching for "Jiruo" in Jiruo, but the decoration of their store is too technical, so science and engineering men can make some comparisons if they are interested. By the way, Wei Dad, who was evaluated by Hangzhou Dad, was full of praise for George's in addition to formaldehyde ability of air purifier.

6. Finally, to sum up: after the renovation of the new house, before moving in, we still recommend professional formaldehyde and TVOC testing if possible, and then make a treatment plan according to the test results. After moving in, we should also pay attention to long-term maintenance. We can put some activated carbon bags and chlorophytum appropriately, and it is best to use a professional air purifier with in addition to formaldehyde capability.
