Does the wooden floor produce formaldehyde when soaked in water?

No, on the contrary, it will reduce the release of formaldehyde, because formaldehyde is easily soluble in water. But it's likely that the blistered floor has been damaged and can't be used properly.

1. If the wooden floor is soaked in water, the surface water on the wooden floor should be sucked dry in the shortest possible time. At the same time, use a vacuum cleaner to absorb water vapor in the splicing gaps of the soaked wooden floor, or use a hair dryer to dry it with cold air, but never use hot air.

Blowing to prevent the surface from drying and deforming due to heat and drying.

2. If it is a small area soaked in water, it is recommended not to pry up the laminate floor to dry, which is easy to cause hard damage to the laminate floor, and it is likely to cause serious consequences that cannot be restored. It is better to quickly remove the baseboard of the floor.

Expansion joints are exposed.

The water vapor is dissipated by the expansion joint, and it usually takes about 3 to 10 days to dry according to the amount of seepage water.

1. On-site inspection.

Sports wood floor maintenance staff, or stadium staff, when they find that the sports wood floor is soaked in water after work, don't panic first, be calm. Inspect the soaking site at the first time to eliminate potential safety hazards, such as whether there are wires, electrical appliances, flammable and explosive materials on the soaking floor, etc.

Then according to the degree of water immersion of the sports wood floor, a solution is formulated.

2. Soak in water lightly.

If the sports wood floor is lightly soaked, the lightly soaked and damp floor can be wiped dry and ventilated. If necessary, disassemble the sports wood floor to observe whether there is water on the ground and observe whether the floor is obviously deformed. If so, it needs to be removed and dried, and reinstalled.

3. Heavy soaking.

Sports wood flooring that is seriously damp or soaked in water for 30 minutes will be deformed, expanded, and lost its luster. Such sports wood flooring is basically scrapped and should be replaced, and attention should be paid to removing the moisture under the floor and drying it.

4. Precautions.

After the sports wood floor is soaked in water, it is important to pay attention to the fact that it cannot be blown by hair dryer, exposed to sunlight, or dried, which will accelerate the serious deformation and damage to the surface of the sports wood floor of the basketball hall.

No, the amount of free formaldehyde emitted in laminate flooring is an important environmental indicator of laminate flooring.

Laminate flooring is composed of four layers of material compounds, namely a wear-resistant layer, a decorative layer, a high-density substrate layer, and a balanced (moisture-proof) layer. Laminate flooring is also known as impregnated paper laminated wood flooring, laminate flooring, qualified laminate flooring is a layer or more of special impregnated hot setting amino resin.

Impregnated paper laminated wood flooring is a floor made of one or more layers of special paper impregnated with thermosetting amino resin, paved on the surface of wood-based board substrates such as particleboard and high-density fiberboard, with a balanced moisture-proof layer on the back, a wear-resistant layer and a decorative layer on the front, and a hot-pressed and formed floor.

Solid wood flooring does not contain formaldehyde, but has a lower formaldehyde content than other types of wood flooring.

According to the relevant test data, the formaldehyde content of naturally growing trees is, that is to say, the raw material for the production of solid wood flooring - wood itself contains formaldehyde.

In addition, the paint used in the paint surface of the solid wood floor also contains a certain amount of formaldehyde, which determines that the solid wood floor contains formaldehyde. In fact, formaldehyde has always existed in nature.

In addition to the wood itself, the formaldehyde in the floor may also come from the surface paint of the solid wood floor, and the paint contains formaldehyde is well known, which is the main formaldehyde of the solid wood floor. At the same time, it may also come from the flooring glue used in the laying process of the real brother wood flooring.

Removal of paraaldehyde method

1. Keep ventilation and ventilation: open windows for ventilation mainly use the circulating air to discharge free formaldehyde, which is the most economical and practical way, but it cannot pollute the source of formaldehyde.

2. Chemical purification method: At present, there are two types of formaldehyde scavengers on the market, one is to purify the air by neutralizing formaldehyde and generating harmless substances; The other is to purify the air by sealing formaldehyde and preventing the volatilization of formaldehyde. Formaldehyde scavengers are also an effective way to absorb formaldehyde.

3. Use activated carbon to adsorb formaldehyde: solid activated carbon has the characteristics of many pores, and has a strong adsorption and decomposition effect on formaldehyde and other harmful substances. The adsorption effect of activated carbon on formaldehyde is obvious, but the amount of activated carbon placed varies according to the size of the space.

In addition, activated carbon needs to be replaced after adsorption to a certain extent.

Solid wood parquet is mainly made of three or more layers of solid wood chips, after multiple processes pasted, the surface is then pressed with high-quality pattern of wood veneer, because the adhesive used in the solid wood parquet is mostly urea-formaldehyde resin glue, containing formaldehyde components, and the release period of formaldehyde can reach 15 years.

Laminate flooring is mainly made of high-density board fiberboard, the surface is a decorative layer and a wear-resistant layer, and a balance layer is added on the back, which is manufactured at high temperature, and urea-aldehyde resin glue is also added in the manufacturing process, which is also the reason for the release of formaldehyde.

How much does the wood floor contain formaldehyde, but the formaldehyde content of the solid wood floor is smaller, and the other content is higher.

The formaldehyde of laminate flooring is not serious. The formaldehyde emission of laminate flooring is less than milligrams, which cannot be counted as serious.

The reason why composite wood flooring contains formaldehyde is that adhesive will be used in the production process of composite wood flooring, and the composition of adhesive and ordinary glue is almost the same, and the glue contains a certain amount of formaldehyde, and will be released step by step to the surrounding environment in the form of gaseous, and the formaldehyde contained in the environment will cause certain harm to the human body, but within a certain limit it is in line with national safety standards.

That is, similar to the ingredients contained in the usual glue, the glue contains a certain amount of formaldehyde, and it will be released step by step to the surrounding natural environment in a vapor state, and the formaldehyde contained in the natural environment will cause certain damage to the body, but the amount of formaldehyde released from the composite wood floor is less than mg, which is not considered to be more serious.

Wooden floors are formaldehyde. The raw materials of wood flooring itself do not contain formaldehyde, but the wood floor uses glue in the production, and the glue contains a certain amount of formaldehyde, so the wood floor will contain formaldehyde. Therefore, when decorating and laying wooden floors, it should be ventilated for at least 3 months to dilute harmful gases in the room and reduce harm to the human body.

In addition to ventilation, other items can be used to reduce the concentration of formaldehyde, such as green plants, activated carbon, etc.

What are the common types of wood flooring.

1. Solid wood flooring.

It is usually made from a single plank of wood and does not require glue, so it is environmentally friendly and has the fragrance of wood. However, the disadvantage is that it is more expensive, and it is usually used in high-end decoration, which can improve the taste of decoration.

2. Three-layer parquet.

This kind of flooring is made of solid wood, and through a special process, three layers of solid wood flooring are staggered and pressed. The bottom layer is made of material with good density, which is pressed layer by layer by a special process, so it is rarely deformed.

3. Multi-layer parquet.

The surface of this kind of flooring is treated with lacquer, and the good things are usually not very environmentally friendly. But because they are all composed of relatively thin wood chips, they are cheaper and have good stability.

4. Laminate flooring.

The biggest feature of this type of flooring is that it is very cheap, and it is very durable, wear-resistant, and very beautiful in appearance. However, a lot of glue is used in production, which is easy to cause pollution.

What to pay attention to when buying wooden flooring.

1. Pay attention to the notch and thickness of the floor.

Usually the notch and thickness are the key to the purchase of the floor, now the standard thickness of the floor is 18mm, if the choice is small or the notch is short, there will be a floor arch or Li Qi, corrugated or walk up with a squeaky phenomenon.

2. Pay attention to the quality of the paint.

The quality of the paint directly determines the color, grade and service life of the floor, and some manufacturers will add color essence to the paint in order to make the floor look more beautiful.

3. Pay attention to package products.

Now a lot of some floors are processed by small factories, after the packaging to make him a self-created brand, this is basically for the purpose of making money, quality and service are not guaranteed, so when purchasing, we must see whether there is a factory address on the packaging box.

4. Pay attention to the moisture content of the floor.

The moisture content of wood flooring is crucial, and the moisture content of the purchased flooring must be equal to the local equilibrium moisture content. When buying a floor, be sure to measure the moisture content, if you don't have a moisture content tester, don't buy its board. The method of balancing the moisture content determination is very simple, first determine the moisture content of the purchased varieties in the exhibition hall, and then open the box to test the moisture content of the purchased varieties of wood floors, if the moisture content of the two is 1%-2% different, it is a qualified product.

5. Pay attention to after-sales service.

After-sales service is a very important part of buying flooring, if you find the floor problem after installation or in the process of installation, the service friend liquid is not good, you can only secretly suffer by yourself.
