How fast does paint volatilize outdoors, and how long is it not harmful to the body? Is there anythi

Paints contain solvents and contain a lot of benzene, ketones, etc. In contrast, ester solvents are a little less toxic. But as long as it is a chemical thing, it is more or less harmful to the human body.

Solvent evaporation can be fast or slow, but no matter how fast, there is still residue in the paint film, and it may be detected after a few years. At present, many solvents are strictly controlled in some developed countries, such as toluene, xylene, acetone, butanone and so on. But the country may not pay much attention to how cheap and how to use.

Perhaps, sometimes solvent poisoning is only one aspect. In the case of some paints, the formulation system may contain plasticizers and other additives, (plastic products also contain plasticizers).Some plasticizers are a little less toxic, but they are very expensive, and cheap plasticizers are also very damaging to people (especially men).

There may also be other additives. Some of these will not volatilize or will be difficult to volatile.

The inside of the house is painted, so it's better to do it free. At least, it has to be used"coatings"Right?

Nowadays a lot of water-based paint products. Comparatively speaking, such a product will be less toxic. However, it is still possible to choose regular brand water-based paint products.

Can't say yes"Water-based paints"I thought it was made of water, it just contained a lot of water to make a solvent. Inside, it still requires a lot of additives and solvents, but it is just a water-based solvent. As long as there are additives, there are solvents, then there is a big difference.

I think that maybe the regular, brand manufacturers, because their products will be sold at a higher price, so in the selection of ingredients, they will take into account a little environmental protection and health, rather than the pursuit of low cost. In this way, there will be less damage to us.

Whether it is paint or coating, long-term ventilation is a must when used in the interior. Don't blindly believe in advertising, what low-smell paint, low taste does not mean that there is no harm to people.

I don't know what kind of paint you use, ordinary paint still has an impact on the human body, in fact, we all live in the world of paint.

As for the magnitude of the impact, ordinary people generally determine its danger to people based on smell.

But for the insider, you can generally understand its toxicity from the name of the paint!

Under normal circumstances, it takes half a month for the toxic smell to slowly disappear. The orientation of doors and windows in the house is important. If the smell is very pungent and uncomfortable, it must be harmful to the body.

There must be formaldehyde in paint, but it's just a matter of how much, the formaldehyde content of well-known brands is less, and there must be more miscellaneous paints. Generally, after the construction of the paint, the benzene can basically be emitted more than 90% in 24 hours, and the rest is relatively slow, it takes several months, and the benzene distribution period in the paint is basically about six months, of course, it depends on the quality of the paint and the ventilation of the house. Paint is a kind of adhesive, as long as it is used in construction, furniture manufacturing and daily life have a wide range of applications, these adhesives will volatilize a large number of organic pollutants when used, the main types are:

Phenol, formaldehyde, acetaldehyde, benzene, ethylbenzene, acetone, diisocyanate and other harmful substances, so we must pay attention to the volatilization of these substances when decorating, so as not to harm our health.

Answer: It can be volatilized in about 3 to 6 months. The volatile point of formaldehyde is 19 degrees Celsius, and when the room temperature is lower than 19 degrees Celsius, formaldehyde does not volatilize in large quantities. For every 1 degree Celsius increase in temperature, formaldehyde concentrations multiple.

You can turn on equipment such as floor heating or air conditioning to accelerate the release of formaldehyde, raise the indoor temperature, and open the window for ventilation before the temperature drops. Activated carbon can rely on its pore structure to passively adsorb some pollutants into its own pores by coming into contact with the surrounding air.

If the interior is decorated with paint, resulting in a pungent smell, it is likely that the formaldehyde content has exceeded the standard, at this time do not rush to move in, find a professional to test it, once the formaldehyde is found to be exceeded, it is necessary to start to do some aldehyde removal measures, the following is for you to introduce several aldehyde removal tips, for you to choose.

1.As long as the local air quality meets the standard, other pollutants will not be introduced, and it is easy to use and low cost, but it needs to be insisted on for a long time, because the release life of formaldehyde is long, and it is easy to repeat the situation when the ventilation is not smooth.

2.Plants can remove formaldehyde, although formaldehyde can be removed, but the amount of formaldehyde it absorbs is very limited, and when the indoor concentration is high, if the plant alone relies on formaldehyde adsorption, the amount is very large.

3.Activated carbon has a large number of irregular pores, in which the pores similar to formaldehyde molecules will adsorb formaldehyde, which can achieve the purpose of purifying the air, but the number of internal pores is limited, when the adsorption is saturated, it may cause secondary pollution, and it must be replaced regularly when used.

4.The air purifier has a good filtering effect on odors and indoor pollutants, and can achieve the purification effect relatively quickly, but it needs to be continuously turned on 24 hours a day, and the purification range of each machine is limited, and each room needs to be configured, so the cost of using it will be relatively high, and the cost of using the whole house is a bit high, and families with enough budget can give it a try.

5.In addition to formaldehyde companies there are many, the methods used are not the same, the commonly used is the plugging method, oxidation method, catalytic method, if it is a reliable company, the effect is obviously slightly higher.

When removing formaldehyde, it is recommended to use a combination of multiple methods to play their respective roles, so as to better stabilize formaldehyde in a safe range!

Generally speaking, the volatile substances of paint mainly refer to VOCs, and the so-called VOCs refer to the substances volatilized by liquid paint after being brushed on the wall and completely drying to form a film.

VOCs have many components and are more complex, among which the main substances harmful to the human body are formaldehyde, heavy metals, benzene, xylene and other substances. It also depends on the type of emulsion, which can be divided into acrylic acid and silicone acrylic emulsion.

Under normal circumstances, the paint will dry in about 8 hours and dry after 24-48 hours. Most VOCs will volatilize during this time, but heavy metals and other harmful substances will volatilize for a longer time, the longest can be more than two or three years.

The basic emitting substances of oily paints are: toluene, xylene, butanol, methanol, propanol, butyl acetate, ethyl acetate, amyl acetate, ethylene glycol, methyl ketone, 200 gasoline, and the basic volatile substances are these;

The volatiles of paint are basically solvent volatiles, and the volatilization of curing agents and paints is also these, but the formulas are different.

In addition to these, other substances in the paint are general, the yellow pigment and red pigment in the pigment are very toxic, because most of the pigments in the paint need red, yellow, blue and white as the basic color toning, so theoretically speaking, the more colorful the paint, the greater the toxicity.

Others such as: titanium dioxide, heavy calcium, pearl powder, zinc powder, carbon black, resin additives, kaolin, precipitated barium sulfate, bentonite are all general.

1. Under normal circumstances, the smell of paint will be almost dispersed in two or three months, but although there is no smell, there will still be some harmful substances such as formaldehyde and benzene. If you want to completely remove these harmful gases, it is best to put the newly renovated room for more than half a year, and you need to open the windows frequently for ventilation during this half year.

2. There will still be formaldehyde, benzene and other harmful gases left in the newly renovated house, it is recommended to buy green plants, grapefruit peel, bamboo charcoal, etc. to absorb the liquid of these harmful gases, the smell of paint in the newly renovated house needs to volatilize for about three months to volatilize, and the ventilation of the window can speed up the volatilization of the paint smell.

The paint contains some harmful substances, which can generally be volatilized in 7 to 45 days, so if the interior decoration is painted, it cannot be moved in immediately. After painting indoors, you can properly open the windows for ventilation to let formaldehyde and other harmful gases emit out. You can also place green plants and activated carbon in the room, which can effectively absorb formaldehyde, and only when the indoor harmful substances are volatilized can you move in.

How to choose paint.

1. Look. When buying paint, the first thing to look at is the packaging information, to see the product composition and whether it is a qualified product. You can also take a look at the test report of the product, pay attention to its environmental protection indicators, heavy metal content, etc., and be sure to choose products that meet national standards.

2. Smell. Be sure to smell the smell when buying paint, if it is an environmentally friendly paint, it smells light and elegant, and there is no pungent smell. So, be sure to ask the merchant to open the lid of the paint can and smell the paint.

After opening the can, you should carefully see whether the paint is delicate and whether it is in a flowing state, if so, it means that the quality is better.

3. Touch. If you feel that the paint is very delicate and silky, then the base lead indicates that the paint quality is good. If you touch the paint surface with your hands, the surface gives people a grainy feeling, indicating that the paint is of poor quality and contains impurities.

4. Use area.

Now there are many types of paint, different functions of paint use occasions, if it is a kitchen, you should use waterproof, mildew-proof paint milk, living room and bedroom to choose safe and environmentally friendly paint.

5. Matching. It is best to choose a matching paint when installing and repairing, such as: you should try to buy the same brand of primer and topcoat, and it also depends on how long the shelf life of the product, the longer the shelf life, the better.

Summary: The above is about how long it takes for paint to volatilize, I believe everyone understands! Paint is a commonly used material in decoration, but the paint smell is more, and now the decoration is used less, you can choose other environmentally friendly materials.

It depends on what kind of paint you're using. If it is an oily blended paint, the environmental protection is relatively poor, the smell is larger, and it will smell for 3 weeks. If it is an oily exterior paint, then the smell is very small, and it is basically empty for one to two months, because after all, it is outdoors.

If it's a water-based exterior paint, congratulations, it's okay for 3 weeks. Because it has no odor, the solvent is water, which is very environmentally friendly. Remember to use something from a well-known brand.
