How long does it take for the paint of a new house to dry without people being harmed by formaldehyd

Generally, the paint on the market needs 1-2 months of long-term ventilation to reduce formaldehyde damage in the amount of ordinary home decoration.

It depends on what kind of paint you are using, how much paint you use, and the quality of the paint and the ventilation of the house.

In the choice of paint, it is recommended to use water-based paint, which is to use water as a dilution, which avoids the toxicity of banana water of oil-based paint and greatly reduces harmful substances such as formaldehyde and benzene. Water-based paint can be moved in about a week.

Interior paints also try to use first-line brands in the choice of brands, because health is priceless.

Before moving in, buy a formaldehyde test box, which is sold online, about 20 yuan apiece, and then check in after the test.

1. Plant elimination method (spider plant, aloe vera).

Spider plant, aloe vera, and tiger tail orchid can absorb a large amount of indoor formaldehyde and other pollutants to eliminate and prevent indoor air pollution;

The fungicides secreted by jasmine, cloves, honeysuckle, morning glory and other flowers can kill certain bacteria in the air, inhibit the growth of tuberculosis, dysentery and typhoid bacteria, and make the indoor air clean and hygienic.

Most plants photosynthesize during the day, absorbing carbon dioxide and releasing oxygen; It breathes at night, absorbs oxygen and releases carbon dioxide.

Some plants are the opposite, such as cacti release carbon dioxide during the day, and absorb carbon dioxide at night to release oxygen, so that at night there is a cactus in the room, which can replenish oxygen and facilitate sleep.

2. Adsorption method (activated carbon).

Adsorption is a solid surface phenomenon. It is the use of porous solid adsorbents to treat gaseous pollutants, so that one or several of its components are adsorbed on the surface of the solid adsorbent under the action of molecular gravity or chemical bonding force, so as to achieve the purpose of separation.

Commonly used solid adsorbents are coke and activated carbon, among which activated carbon is the most widely used.

Activated carbon has adsorption function for benzene, toluene, xylene, ethanol, ether, kerosene, gasoline, styrene, vinyl chloride and other substances.

Smell of paint: Freshly painted walls or homes have a strong smell of paint, and to get rid of the smell of paint, you only need to put two basins of cold salt water indoors for a day or two to get rid of the smell of paint, or soak the onion in a pot, which is also effective.

Most of the paint is benzene, there is not much formaldehyde, and 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.

1. The formaldehyde of the paint is emitted in about three months.

2. The smell of paint is very unpleasant, in order to solve the smell of paint after decoration, some green plants, grapefruit peel, bamboo charcoal and other substances will be selected to absorb the smell of paint at home, and the smell of formaldehyde in paint will be emitted after two or three months.

3. Physical and chemical properties of paint: paint is a viscous oily pigment, flammable and insoluble in water when it is not dry, slightly soluble in fat, soluble in alcohol, aldehyde, ether, benzene and alkane, soluble in gasoline, kerosene and diesel.

4. Regardless of the variety or form, the paint is composed of three basic substances: film-forming substances, secondary film-forming substances and auxiliary film-forming substances: film-forming substances Xiaofeng: also known as binders, most of the film-forming substances are organic polymer compounds such as natural resins (rosin, lacquer), coatings (tung oil, linseed oil, soybean oil, fish oil, etc.), synthetic resins and other mixed ingredients, which are formed by high-temperature reactions, and there are also inorganic combinations of paints.

The formaldehyde in the paint can be volatilized in about three months.

Strengthen ventilation to remove formaldehyde: opening windows for ventilation to strengthen air circulation and accelerate the release rate of formaldehyde is the most important means to remove formaldehyde. Under normal circumstances, the new house will be renovated after the window will be opened for ventilation for a period of time, it is best to open all the windows in the opposite direction of the house, so that the air convection can be strengthened, in some times when there is no wind and less wind, if the formaldehyde concentration is too large, you can also use an electric fan to strengthen the flow.

If you use an electric fan, the floor fan works better.

Generally speaking, the formaldehyde in paint has an evaporation period of about 2-3 months, and if the indoor air circulation is good, it can be volatilized more quickly. However, the rate of formaldehyde evaporation may vary depending on the temperature, humidity and air flow in the room, and it is not possible to determine the exact time.

The evaporation time of formaldehyde in paint depends on a variety of factors, such as temperature, humidity, ventilation, type and thickness of the paint, etc. In general, formaldehyde in paint will evaporate and slip out within a few days to a few weeks. After applying paint, you should keep the indoor group resistant ventilation and try to avoid staying indoors for a long time to reduce the health effects.

Formaldehyde is continuously released, the release period can reach 3 to 15 years, the release source is relatively wide, and it is difficult to be completely removed in a short period of time, so how should we deal with it, the current more mature is to stabilize the concentration of formaldehyde in a safe range, recommend several useful methods to everyone.

1.Open all doors and windows to promote air circulation, so that harmful gases can be discharged to the outside through the flow of air, which is simple and effective. However, this method should be used to maintain ventilation for a long time, and a large fan can also be used to enhance the wind and assist in ventilation.

In this cycle, forced ventilation for a month, the odor in the room will be greatly reduced. For some movable furniture, try to place vents so that odors can be discharged directly to the outside.

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 to remove formaldehyde is the most commonly used way to remove formaldehyde in life, and the cost is low, but activated carbon is prone to adsorption saturation in a short period of time, and it needs to be replaced or dried after saturation. Another point to note is that if the amount of activated carbon is not enough, it will not play much role in removing formaldehyde indoors.

4.The blades of the fan can cut the air to promote the airflow in the process of rotating, so as to realize the displacement of indoor and outdoor air, accelerate the discharge of formaldehyde-containing air, and effectively reduce the concentration of indoor pollutants, but it can only treat the symptoms but not the root cause, and this method may not be practical in the warm season.

In summary, after the decoration of the new house, the release of formaldehyde is large, the release time is long, and the treatment of formaldehyde by a single method will inevitably be a little difficult.

After the paint film is completely cured, the evaporation is basically over - different types and brands of paint have different drying and curing times, and there is no way to explain them at one time. Alkyd paint cures slowly, generally high-quality brands, curing at room temperature, it takes a day or two, if the light and ventilation, the curing time will be shortened a lot!

After the general paint construction, the benzene can basically be emitted more than 90% in 24 hours, and the rest is relatively slow, it takes a few months, and the benzene distribution period in the paint is basically about six months, which actually depends on the paint quality and the ventilation of the house.

--Air purification in Shenzhen.

There are many harmful substances in the paint composition, such as formaldehyde, VOC (toxic volatile gas), heavy metals, etc., so most paints contain formaldehyde, and inferior paints will have a pungent smell. Generally speaking, the content of these substances in brand paint is relatively low, and the environmental performance is better, for the sake of your own health, it is recommended that you buy brand paint more safely. For the formaldehyde in the paint, it must be treated in time, and after the paint is used in the decoration of the new house, we must pay attention to the smooth ventilation of the room and let the formaldehyde volatilize as soon as possible.

Or if you have conditions at home, you can use an air conditioner or buy an air purifier, although the cost is high, but it is better for removing formaldehyde, you can try.

About three months.

The formaldehyde of the paint is emitted in about three months. The smell of paint is very unpleasant, in order to solve the smell of paint after decoration, some green plants, grapefruit peel, bamboo charcoal and other substances will be selected to absorb the smell of paint at home, and the smell of formaldehyde in paint will be emitted after two or three months.

If high-quality latex paint is used, the content of harmful components itself is not large, and the volatilization is accelerated through some solutions, so the indoor formaldehyde will be almost volatilized in a month, so at this time, after the test is done, the air quality can also be moved in.

Formaldehyde in the paint must be there, but the question of how much, most of the paint construction, 24 hours of benzene can basically emit more than 90%, the rest of the volatilization will be very slow, the emission period of benzene in the paint is basically about six months.

Two or three months can be, the paint contains less formaldehyde, mainly containing benzene, benzene is also a harmful substance, to remove it in time, you can raise some spider plants, pothos and other plants indoors, the most important thing is to open the window every day for ventilation.

Formaldehyde in paint will generally volatilize for more than three months, and the paint smell can be removed by ventilation, mainly the formaldehyde contained in the material, the release cycle is longer, and it should be ventilated for a month before moving in.

Latex paint contains less VOC content, and some products are zero VOC and generally brush and live. Generally, the release cycle of latex paint is about two weeks to two months. The formaldehyde content in putty and plates is very high, and it cannot be completely released for several years.

Because some chemicals used in latex paint are toxic, it does not mean that latex paint is very toxic to people or that people are poisoned after touching or smelling it. Rather, it is said that the latex paint has done the best in environmental performance, and it is already within the national environmental protection standards, as long as the ventilation is maintained for about a month after the decoration is completed, it will basically not cause harm to the human body.

Latex paint should be said to be a green environmental protection product, but the solvent also contains a small amount of formaldehyde, formaldehyde is a toxic gas, the human body inhales too much will cause allergies and throat problems. The solvent also contains other organic solvents, which are benzene, toluene, etc., which are harmful to the human body.

It depends on the environment, if the painted items are placed in the yard in the shade to dry, after two or three days, there will be no taste. If you are in a closed environment, you can't disperse for half a year!

It is best to ventilate the house for more than half a month before starting to move in, and you can also put green plants in the house to help formaldehyde dissipate.

It will take about 3 years to volatilize, and if you want to buy a famous brand at home, you still need to ventilate and turn on more fans

The formaldehyde smell in the paint can disappear in about 2 months if it is ventilated normally.

Follow the 2 methods below to make it disappear in as little as 1 month.

1. Strengthen ventilation.

Open window ventilation is one of the more commonly used methods at present, and keeping open windows for ventilation every day can strengthen indoor and outdoor air circulation and alleviate the content of formaldehyde to a certain extent. In case of inconvenient ventilation weather or other situations, you can also use a fan to assist in blowing.

2. Physical decomposition.

This is a deodorization material recommended by the aldehyde remover, Baizao Na not only purifies faster, but also adds a double group of decomposition components, which can automatically decompose the paint smell, and three years of sun-free, put it at home and don't worry about the problem of secondary pollution, and can continue to ensure that the formaldehyde in the new house is not **.

At present, the content of formaldehyde in paint is very small, under normal circumstances, the formaldehyde content of regular latex paint brands is less than 10mg kg, which is basically in line with the country, so the formaldehyde in the paint has little impact on the human body.

And the current latex paint basically contains formaldehyde is free formaldehyde, and the content is very small, but there is very little formaldehyde in the paint, but it will contain TVOC organic volatile gases, as well as benzene or xylene and other harmful substances, but the regular latex paint that meets the national environmental protection standards, these components can be used normally. It's just that I can't move in time, and I generally need to disperse the smell of latex paint.

Precautions for the use of paint1. To maintain air circulation, there can be no fire on the construction site, no welding construction, and smoking is strictly prohibited.

2. Avoid contact with eyes, and use protective equipment such as protective goggles, masks, and gloves when using.

3. If you accidentally get it, rinse it with neutral detergent and warm water.

4. If the can is not used up after opening, it should be sealed to avoid water pollution.

5. Construction can not be carried out in rainy or windy weather, and the wet wall can only be constructed after drying.

After a few days, it will be evaporated. Except for those who are not qualified.

Latex paint. Formaldehyde needs to be dried for more than three months before most of the formaldehyde can be removed before it is suitable for occupancy.

Formaldehyde is abundant in a variety of coatings and sheets.

The adhesive is slowly released by the diffusion effect of the molecules. In these three months, the owner should try to open the windows in the house for ventilation, when the formaldehyde in the indoor air is emitted, the formaldehyde concentration will be reduced, and the formaldehyde in the new furniture and building materials will continue to be released into the air, and the speed will be accelerated.

In addition, activated carbon can be utilized.

etc. to remove formaldehyde. Formaldehyde has obvious reducibility.

Therefore, all kinds of oxidizing properties.

can remove formaldehyde.
