I. Is the formaldehyde in the geothermal floor exceeding the standard?
(I) The formaldehyde emission standard for the geothermal floor
The formaldehyde emission of the geothermal floor is less than or equal to 1.5mg/L, which means it meets the new national standard and meets the requirements of indoor environmental protection and health.
(2) Geothermal floor formaldehyde self-test method
1. Animal and plant test method
Animal or plant detection can be used. By observing the reactions of animals and plants, formaldehyde can also be detected to a certain extent. If the plants wither and die, it happens right after moving into the new house. Raised pets are sick, do not eat food, have low resistance, and have decreased vitality. They always like to stay quietly. If this happens, and your family also has a similar reaction with low resistance, it can basically be determined that the content of formaldehyde in the house is unqualified.
2. Self-experience testing method
Judging according to one’s own feelings, after the whole family moved into a new house, they would catch a cold collectively, their immunity would be low, and they would be prone to headaches and dizziness. Decreased energy and fatigue. Feeling irritating odor, especially when close to a piece of furniture, the eyes feel watery, etc. At this time, it is necessary to do a more precise inspection as soon as possible, and keep the room well ventilated.
3. Formaldehyde self-test box
The formaldehyde self-test box can be tested at home by itself. It was developed by the National Institute of Quarantine Sciences and conforms to the The chemical inspection method stipulated by the national standard, the inspection effect is guaranteed. It is suitable for ordinary residential houses, generally operate according to the instructions, and the concentration range of formaldehyde can be measured in about half an hour.
(3) Geothermal floor formaldehyde can be released in a few years
The time for formaldehyde release from geothermal floor varies, some are two or three months, Some can even reach several years or decades, mainly depends on what substrate you choose for the floor.
If you choose a slightly better quality solid wood floor, it will release less formaldehyde, and the release time will be shortened, which may only take a few months. As long as the formaldehyde does not exceed the standard, the harm to the human body is not particularly large.
And if you choose a composite geothermal floor, according to its structure, it is divided into four layers, and one layer is the substrate layer. In order to ensure the bonding effect, some businesses will use inferior glue, so formaldehyde The release time will be relatively long, which can reach several decades. If you choose environmentally friendly glue, the release time will be shorter.
Second, what should I do if the formaldehyde exceeds the standard under floor heating
(1) The relationship between the release of formaldehyde from geothermal floors and temperature
The amount of formaldehyde released in the board is directly related to the temperature. If the temperature increases, the amount of formaldehyde released will gradually increase. The volatilization point of formaldehyde is 19°C, and the concentration increases by 0.4 times for each degree of temperature increase. And if the indoor temperature reaches above 25 ℃, the amount of formaldehyde released will be greatly increased. Generally speaking, the temperature of underfloor heating cannot exceed 25°C, which will have less impact on the release of formaldehyde.
(2) What should I do if the formaldehyde exceeds the standard when the floor heating is turned on?
1. When the floor heating is turned on, the windows can be properly ventilated to speed up the volatilization and release of formaldehyde in the floor , so as not to enter the indoor formaldehyde and then be absorbed by the human body and harm the human body.
2. Chlorophytum and aloe vera among plants are experts at purifying the air and adsorbing harmful substances, and at the same time have a strong ornamental value and also play a decorative role.
3. If the budget is limited, some substances with good adsorption properties such as activated carbon and nano-active ore can be placed in those places to absorb the remaining harmful substances such as formaldehyde that may appear for a long time.
4. Buying a high-quality, energy-efficient air purifier is the best way to remove aldehydes.
