Where is the formaldehyde in the new house hidden and where you can buy air purifierGuangzhou Olansi Healthcare Co.,Ltd
I thinnk everyone knows that formaldehyde is very harmful to the human body. Excessive inhalation of formaldehyde, usually caused by olfactory abnormalities, irritation (pungent, tearing), abnormal lung function, long-term exposure can cause a variety of chronic respiratory diseases, causing nasopharyngeal cancer, colon cancer, infant chromosome Abnormalities can also cause memory and mental decline in adolescents, and can even cause leukemia.
When it comes to formaldehyde, many people think that it is related to the decoration and building materials of the new house. Often the topics we see are “How long will the new house be renovated”, “How to remove formaldehyde after decoration”, “Formaldehyde carcinogenicity”, etc. This gave us a misunderstanding and a one-sided understanding of the relationship between formaldehyde and decoration.
Let me talk about the formaldehyde in the decoration process. When it comes to decoration and formaldehyde, everyone’s reaction is often synthetic wood and synthetic building materials. Therefore, when we saw the “zero formaldehyde” in the decoration selection, it was easy to take a high look. I felt that the business dare to promise that it can withstand the test. If the “zero formaldehyde” board and furniture are used, at least to some extent, formaldehyde can be inhibited. It’s harmful. This is a misunderstanding!
In fact, formaldehyde is not something that must be used in decoration. It is only hidden in the coatings and adhesives used in the construction process. It is not for anyone who wants to add formaldehyde in it. In fact, formaldehyde itself is not useful for decoration, but Formaldehyde-containing urea-formaldehyde resin is an essential adhesive for decoration.
This means that even if all the materials you buy are “zero formaldehyde”, as long as you use the adhesive, you are already exposed to the “host” of formaldehyde. The commonly used adhesive is urea-formaldehyde resin. There is a large amount of formaldehyde residue in the production process of urea-formaldehyde resin. It is called free formaldehyde. This part of free formaldehyde will be released when the coating is leveled and solidified. This is the direct danger of formaldehyde decoration. source.
In the process of decoration, there are really too many places to use the adhesive! Putty, paint, glue, wallpaper, laminate flooring, particle board, MDF, even solid wood sheet… Almost everything used in home decoration contains formaldehyde, so I don’t want formaldehyde in the home improvement process. Sorry, this world Not so beautiful yet!
Since we can’t avoid it, all we can do is to minimize the formaldehyde content of each item! For example, wood flooring, try not to be composite, or as few layers as possible! The paint for solid wood furniture is as good as possible, the formaldehyde content is lower… As long as the formaldehyde content is within a certain range, it is not as terrible as imagined!
As mentioned earlier, formaldehyde is acceptable within a certain range of indicators, but in a situation that occurs in our daily lives, it accelerates the volatilization of formaldehyde – that is, high temperatures.
According to research, the volatilization point of formaldehyde is 19 ° C, and the temperature rises by 0.4 times for every degree of temperature rise, especially in the spring and summer, the temperature rises more severely and the concentration will exceed 3 times of normal.
Originally, the temperature dropped in winter, and the amount of formaldehyde released was also reduced. However, because people need to turn on heating equipment at home, such as floor heating in the north and air conditioning in the south, the indoor temperature rises and the formaldehyde hidden in paint, floor and furniture is released in large quantities. Toxicity is 10 times higher than normal
In fact, formaldehyde can’t be completely eliminated. We can only use all means to control it in the range of no harm. The method of formaldehyde removal on the network can be divided into several types: the ventilation green plant purifier activated carbon… The public and the public husband said that the woman is reasonable, then let’s take a look together, what is the truth of them…
Green plant: The effect of green plant purifying air to release oxygen is unquestionable, but the specific purification effect of formaldehyde has not been proved by relevant institutions. In fact, the role of plant formaldehyde is very small, the formaldehyde we breathe every day is much stronger than its effect!
Activated carbon: The principle of activated carbon purifying air relies on its well-developed pore structure and surface area, which can contact the surrounding air to a large extent, and “passively adsorb” some pollutants into its own pores.
According to relevant experiments, after the activated carbon was placed in the environmental chamber for 3 hours, the formaldehyde concentration in the cabin was reduced by 24%. This value is 19% relative to the natural attenuation, indicating that the effect of activated carbon on formaldehyde removal is very weak.
After the adsorption of activated carbon is saturated, if the temperature rises, the adsorbed formaldehyde will be released again, which makes the indoor formaldehyde concentration higher, and this secondary pollution is very serious.
Therefore, the activated carbon needs to be taken indoors regularly, so that the absorbed formaldehyde is released to the outside and then taken back to the indoor use. The time and the degree of adsorption are difficult to grasp.
Ventilation: The so-called ventilation to remove formaldehyde is to release the volatilization of formaldehyde faster by the indoor air flow rate. In fact, it takes only a few minutes to blow the formaldehyde in the air, but the release of formaldehyde is constant, so the ventilation time cannot be Too short, and long-term ventilation is theoretically ok, but for the cold winter, this feasibility is not great.
Now is the air purifier. Indoors, you can use the air purifier’s circulation purification function to accelerate indoor air flow, so you can breathe without opening the window!
