Formaldehyde is present in paints. Some additives will be added in the production of paint, formaldehyde is one of them, but the content of formaldehyde in good paint is very small, within the safe range, can be used normally, but if the quality is not good, there is more formaldehyde. When using paint in decoration, it is necessary to open windows for ventilation in time to accelerate indoor air circulation, which will also accelerate the volatilization of formaldehyde.
Inhalation of high concentrations of formaldehyde can cause respiratory diseases, sneezing, coughing.
It is accompanied by a burning sensation in the nasopharynx, nosebleeds, and so on. Long-term exposure to formaldehyde also has effects on the respiratory system, nervous system, cardiovascular system, endocrine system, and digestive system.
There are toxic effects on the reproductive system and kidneys. Constitutional symptoms include headache.
Fatigue, loss of appetite, palpitations.
Insomnia, weight loss, and autonomic disorders. After the vaporized formaldehyde air sample is brought into the column by carrier gas, the components are separated from each other due to the different molecular forces between the stationary phase in the column and the components in the sample, as well as the different times for each component to flow out of the column.
With a proper identification and documentation system, the staff can mark the time and concentration of each component flowing out of the column chromatography. After that, a qualitative analysis of the aldehyde-containing air can be performed based on the timing and sequence of peaks shown in the figure;Depending on the height and area of the peak, aldehyde-containing air can also be quantitatively analyzed. The physical adsorption method is also effective in removing the smell of indoor paint, such as leaf mud and activated carbon.
etc., can adsorb and decompose harmful substances such as paint smell. We should pay attention when using activated carbon, because activated carbon is easily saturated, so it needs to be in contact for a long time before it can continue to be used.
If you find activated charcoal too troublesome, it is recommended to consider using long fermented wide mud. Flavor. Formaldehyde has a pungent smell.
If you smell a pungent smell in the room, it means that formaldehyde is seriously exceeded. If the smell is not very strong, but it lasts indoors for more than 1 hour, and you feel uncomfortable in your throat, it means that the formaldehyde exceeds the standard and is not suitable for living. Find a professional third-party testing agency.
Identification. Generally speaking, the test is more expensive, so you can decide according to your actual situation.
-
Yes, so the detection of formaldehyde requires special tools, such tools, that is, the molecules of formaldehyde can be found very well.
-
There is also formaldehyde in the paint, you can close the doors and windows, and then use a special formaldehyde measurement ceremony to measure, you can detect the formaldehyde content.
-
There is also formaldehyde in the decoration instrument, if you want to detect the formaldehyde content, we can measure it through the test strip that specializes in detecting formaldehyde, and in the subsequent decoration process, it is best to choose the decoration material with less formaldehyde content or no pollution.
-
I think of course there is formaldehyde, which can be measured with professional instruments.
-
Formaldehyde is contained, but very little. The harmful substances in the paint mainly include: formaldehyde, VOC (toxic volatile gas), heavy metals (mercury, chromium, lead, etc.), toluene compounds, etc.
Generally speaking, the content of these substances in brand paint is relatively low, and the environmental performance is relatively good. It is recommended that if the formaldehyde exceeds the standard, please treat it in time.
1. Improve indoor ventilation equipment: install indoor fresh air ventilation system.
2. Fruit deodorization method: place pineapple, orange peel, pepper, onion, etc.: divide them into small portions and place them in all corners of the room, as well as the place where the decoration smell is the strongest, and the decoration taste is generally greatly reduced within a week.
3. Use tea: make tea with boiling water, tea should be put more to ensure that the concentration of tea is enough, when the tea vapor volatilizes, use a plastic poke to divide it into each room for fumigation. After the water cools, reheat the water, and repeat this several times, and the taste of the interior decoration is greatly reduced.
4. Plants: orchids, cacti, aloe vera and other plants are suitable for indoor placement, which is inexpensive and beautifying. In the case of occupancy, 1 pot of 2 square meters can be placed in the bedroom and living room.
Within a month, the smell of decoration will be lowered. Aloe vera can also act as a monitor for indoor environmental pollution, and when the indoor air quality is poor, many small spots will grow on the leaf surface, and vice versa, the indoor air quality is good.
5. Ventilation: Try to keep the indoor window open for ventilation for a long time, and you can also use an electric fan to assist in accelerating the indoor and outdoor air convection flow, and forced ventilation for a month, the decoration smell will be greatly reduced.
6. Physical adsorption method: materials such as Mayan blue and activated carbon are good formaldehyde adsorbents, and there are many tiny pores in their materials, so they can absorb a lot of unsaturated particles in a free state, and the effect of activated carbon will be worse.
7. Catalytic decomposition reaction: most of the methods of air purification only remove the decoration smell, but have no practical effect. Professional formaldehyde removal products can directly control pollution sources, and use oxidation to decompose volatile organic compounds and microorganisms in the air, with the most efficient and fast effect.

It is a paint that contains chemical agents, and the paint containing formaldehyde is mostly used for waterproofing and anti-corrosion, marine paint, and wood and iron primer are more common, but the content is not high, the release is faster, and it is not easy to cause too much formaldehyde harm to the interior.
-
This is not necessarily, general paints are contained, but some latex paints have a higher formaldehyde content than paints.
-
Generally, there is, but now most of the technology is developing in the direction of no formaldehyde....There are also some that are not included in the market, so you'd better consult more when buying! Let's take a look at its ingredients!
-
The paint is formaldehyde-free, it contains benzene, and the plate cylinder and glue are formaldehyde-contained.
-
Paint is now a generalization.
Bai read, there are many kinds of du, such as latex paint for family homes, wall dao skirts are generally Puhuitong blending paint, polyester paint for woodware, anti-rust paint for industrial steel structures, and so on. I am a painter, and I know that many types contain formaldehyde, which is related to a cost and use. Like the steel structure with a good 17 kg of pentium paint, it will cost about 150, which is good in the steel structure.
If you talk about latex paint, a bucket of 20 kilograms, hundreds or thousands of pieces are normal, depending on customer needs. For example, a paint does not contain formaldehyde, which is very environmentally friendly and healthy, but indicators such as construction industry, brightness, color, can last for several years, and the surface is dry and hard, and other indicators can not be used. Like general industrial paints, there is no consideration of formaldehyde.
Off topic, most paints contain formaldehyde, and if you don't have formaldehyde, you need to find a painter to get it.
-
Most of them do not contain formaldehyde, so I asked for reuse when I bought them.
-
When decorating the house, it is inevitable to use paint, the paint contains formaldehyde, even if it is environmentally friendly paint, it is not possible to guarantee zero formaldehyde, in the case of uncertainty, you can do a formaldehyde test to detect whether the indoor formaldehyde content exceeds the standard, once it exceeds the standard, it is necessary to immediately carry out aldehyde removal measures, the following is for you to introduce several methods of removing formaldehyde, hoping to help you efficiently control formaldehyde.
1. Putting some green plants at home can also effectively remove odors, especially like pothos, spider plant, aloe vera, monstera, cactus, ivy, etc., which can effectively absorb harmful gases. In addition, large plants such as the Ping An tree and the camphor tree, which are more popular on the market, can release a fresh gas on their own, which makes people feel happy, and is also more suitable for removing the smell of new furniture.
2. If you want to remove the formaldehyde and odor in the interior as soon as possible, the first thing to do is to open the window for ventilation, open the cabinet doors and drawers at the same time, and dilute and discharge the formaldehyde to the outside through air convection. Although this step is simple, it is also necessary to pay attention to the weather conditions, so as not to break the newly renovated home environment with strong wind and rain.
3. There are a large number of irregular pores inside the activated carbon, among which the pores similar to the formaldehyde molecule will adsorb formaldehyde, which can achieve the purpose of purifying the air, but the number of internal pores is limited, and it may cause secondary pollution when the adsorption is saturated
5. We all know that formaldehyde is volatile at high temperature, and we can use some heating equipment to increase the temperature at home a lot, so that a large amount of formaldehyde gas can be volatilized, and then formaldehyde can be removed by opening windows for ventilation. Repeated operation a few times, you can remove most of the formaldehyde in the home, but we must pay attention to safety when using heating equipment to avoid fire.
6. The fan can assist in opening the window for ventilation, many houses are not necessarily transparent, and the effect is not very good when the window is opened, so the fan can be used to accelerate the air flow in the room and quickly discharge the free formaldehyde in the air.
In the process of decoration, we often have a headache is to choose the paint and coating at home, a lot of brands, are boasting that they are good, not people in the industry do not understand, to summarize my views on several more famous brand products, I hope to help you when choosing products. >>>More
1. Open windows for ventilation.
The most important thing after the decoration is to open the windows for ventilation, open all the windows, preferably convection wind, you can blow away the smell of the house, it is recommended that it is best to ventilate for half a year before living. >>>More
Hello! Newly renovated houses, taking into account the health of the occupants, in the case of paint and coatings on the walls and furniture at home, there will be a certain amount of formaldehyde content volatilization, you can use a formaldehyde detector to detect whether it exceeds the standard, or ask a professional indoor environmental assessment testing agency to test it is more appropriate!
Natural wood should be used as much as possible for decoration. >>>More
1. Open window ventilation: window ventilation is the simplest and most direct way to remove formaldehyde, but removing formaldehyde is a long-term work, and the effect of window ventilation is slow, so it can only be used as an auxiliary method. >>>More
