Where does formaldehyde in furniture come from

The new home has a smell to distinguish whether it is a wood smell or a chemical smell, the chemical smell can be ventilated first, and the wood odor does not need to be treated. Generally, after decoration, it is necessary to ventilate for more than half a year before you can move in, and if you have a baby at home, you need to ventilate for a period of time before you can move in. You can put some plants indoors that can absorb formaldehyde.

1. You can open the doors and windows for ventilation first, and after a period of time, wait for the formaldehyde to be released for a period of time, and then use Ye Guangni to absorb and decompose formaldehyde.

2. Use a steam engine, close the doors and windows, increase the temperature and humidity of the home, turn on the air conditioner, sprinkle water, etc.

3. Use the plant's herbal formaldehyde scavenger, aloe vera, and moso bamboo extract.

4. In addition, placing orange peels, lemon peels and other items in the room will not have a very quick effect.

Formaldehyde is an indispensable main component of woodworking boards, paints and other materials, as long as these materials are used in the production process of your furniture, the furniture must contain formaldehyde after it is done.

Formaldehyde is the adhesive that comes from the production of furniture panels, and it is the main raw material of the adhesive.

Lumber (not solid wood).

Paint (solvent-based paint full of pungent odor, water paint does not contain formaldehyde) wallpaper (free formaldehyde in the pulp, or choose good quality, do not require good quality and low price) glue (adhesive).

The subject got a wrong concept, not "furniture" contains formaldehyde, but furniture contains formaldehyde, formaldehyde is a colorless, odorless volatile gas, it mainly exists in paint, glue, composite board inside, and most furniture is not made of logs, are made of composite wood boards, so it will contain a lot of formaldehyde.

In order to make these composite boards bonded together, some glue will be used, and these glues will contain a large amount of formaldehyde, and when the indoor temperature and ventilation degree change, formaldehyde will be gradually released. In addition to furniture, such as ceramic tiles, paints, glues, and furniture paints contain a certain amount of formaldehyde, if some other special materials are used in the home, if these materials are not natural, they will also contain a certain amount of formaldehyde.

Like the early years of the home cabinet, the use of natural wood, not synthetic composite wood boards, which contains almost zero formaldehyde, unless it is painted with some paint containing formaldehyde, otherwise it does not contain formaldehyde. But because of the prohibition of deforestation, there are very few logs, even if there is, the cost is several times that of composite wood boards, more than ten times, even if it is a custom cabinet from some famous brand manufacturers, it also contains a certain amount of formaldehyde, but the amount of formaldehyde does not exceed the standard.

If it is formaldehyde contained in composite wood boards, volatilization requires a process, if some cleaning methods are used regularly, it will take at least 30 days, and if the normal rate of volatilization is followed, it may take more than three or six months. The speed of formaldehyde volatilization has a lot to do with the ventilation environment and indoor temperature. Activated carbon, pothos, diatom mud and other substances can be used to assist in the removal of formaldehyde, or you can contact the company that removes formaldehyde to help remove it.

However, I personally suggest that you should ventilate more, and then find a way to increase the temperature in the lower room to help the volatilization and emission of formaldehyde.

According to the national regulations on the formaldehyde emission of interior decoration materials, wood-based panels and their products, the formaldehyde emission of wood-based panels that meet the E1 standard shall not exceed mg m3, and the glue that continuously releases formaldehyde from wood-based panels is an adhesive, generally known as formaldehyde adhesive. The cost of resin glue is low, it is relatively easy to make, and it can be produced in large quantities, so it has become a must-choose manufacturing material for major furniture manufacturers. Once furniture of such material is installed in the home, formaldehyde is continuously released.

At the same time, the production threshold of formaldehyde-free board is very high, so in the furniture industry, the production capacity of formaldehyde-free board brands is not much, some brands claim to use solid wood particle board, in the production of formaldehyde-free adhesives, formaldehyde emission is better than the national standard, but the enterprise standards it adheres to are recognized by the industry, and it is difficult for ordinary consumers to verify; Some brands use MDF, the formaldehyde emission is lower, and the corresponding reference standard is unknown; Some brands claim to use additive-free wood boards and solid wood boards, and these data are subject to the judgment of consumers.

I believe that we are no stranger to formaldehyde as a harmful gas, in recent years, due to the list of bad cases caused by excessive formaldehyde, as early as 2016, a number of college students in Jilin University were found to be poisoned by formaldehyde. In the same year, in a newly renovated primary school in Shanghai, students experienced vomiting and rashes, resulting in the installation of a large number of composite panels in the classroom, resulting in excessive formaldehyde concentrations. So many staggering cases have been a reminder to pay attention to the serious problem of formaldehyde.

Compared with the removal of formaldehyde after decoration, the prevention of formaldehyde is also extremely important! Why this set of data should be set out to correct the idea that many consumers are not buying properly, do not put too much energy on the price comparison of furniture, which has reached the national environmental protection standards should be clarified by the parameters of the furniture, and then compare the size and style of the furniture.

Up to fifteen years, especially after the decoration is completed within six months, the formaldehyde incubation period, the formaldehyde concentration is likely to reach the highest point, why there are so many formaldehyde gathered in the room The reason is mainly due to the introduction of various building materials and furniture, because the quality was not strictly controlled before, resulting in the furniture containing formaldehyde filling the whole room, we can see that the improved screening standard furniture is necessary. Fortunately, the number of environmentally conscious furniture consumers is slowly increasing, and to avoid formaldehyde, you should know how to control the source, focusing on prevention, combining prevention and control.

GBT 19941-2005 Leather and fur chemical tests Determination of formaldehyde content.

GB 18401-2001 Limitation of formaldehyde content in textiles.

GB 18584-2001 Interior decoration materials - Limits of harmful substances in wood furniture.

1. Formaldehyde in leather and fur: due to its versatility and excellent cost performance, formaldehyde has been applied in many industrial fields. In leather, formaldehyde is an effective cross-linking agent, its effect is beyond the reach of other aldehydes, formaldehyde as a major raw material for the synthesis of leather chemicals, it is difficult to be replaced in a short time.

In fur, in addition to the synthesis of special fur chemicals, formaldehyde is still sometimes used as a tanning agent due to its low price and high quality of the resulting fur. This has also led to higher levels of formaldehyde in some fur products.

2. Textile fabrics: formaldehyde has lively reactivity and low price, and can be combined with cellulose fiber hydroxyl through hydroxymethyl, which has the functions of preventing fabric shrinkage and making the product wrinkle-resistant, flat and dry, anti-static, and improving the durability of printing and dyeing auxiliaries on textiles. Therefore, it is widely used in fiber production and printing and dyeing finishing.

Upstream formaldehyde in textiles mainly comes from preservatives, stiffening agents, resin finishing agents, artificial resin crosslinking agents, electrostatic flocking adhesives, printing and dyeing pigments or reactive dye fixing agents. Most of the chemicals such as finishing agents, cross-linking agents, fixing agents, flame retardants, softeners, and waterproofing agents are synthesized with formaldehyde as raw materials or release formaldehyde at the same time of use, and the formaldehyde content produced is high, resulting in the formaldehyde content on textiles exceeding the specified minimum limit value.

3. Wood-based panels: wood-based panels need to use a large number of adhesives in the manufacturing process to bond between wood and wood, the adhesives are mainly urea-formaldehyde resin glue or phenolic resin glue, these glues are viscous and cheap, and are widely used in the field of wood-based panel manufacturing.

To quickly remove formaldehyde, you can choose to find professional formaldehyde removal products such as Shenguang aldehyde removal enzyme, and the formaldehyde content can be reduced to the national standard in about 7 days after the treatment is completed.

Formaldehyde is on furniture, generally because the furniture is a man-made synthetic material. It will be more noticeable on new furniture, but after dilution for a while, it will dissipate.

Formaldehyde on furniture is mainly because in the furniture manufacturing process, the plates are mainly bonded together through glue, the glue itself contains formaldehyde, the surface of the furniture is still painted, and the paint also contains a large amount of formaldehyde.

First, glue is mostly used in furniture production, and glue contains formaldehyde. Second, the furniture is painted with paint, and there is a large amount of formaldehyde in the paint. Some furniture also has preservatives, which also contain formaldehyde.

The panels of furniture are generally composite boards, mostly particleboard and MDF, which need to be treated with glue adhesive in the process of pressing into shape, so there is formaldehyde in the glue.

Of course, it is a plate, the paint has a large molecular structure and is easy to volatile. The sheet can be volatilized for more than 15 years after being wrapped. In order to reduce the cost, the MDF inside is very inferior, and the surface cover is very beautiful!

Formaldehyde in furniture mainly comes from the adhesive in the board, and almost all of the panel furniture or custom furniture on the market contain formaldehyde, but you don't need to panic about it, the formaldehyde release within a certain standard will not threaten people's health. Consumers can choose a big brand with a good reputation before purchasing, require merchants to show relevant environmental protection certificates during the purchase process, and invite professional institutions to help detect and remove formaldehyde after purchase.

Many people may not be familiar with formaldehyde pollution when it comes to it, because not everyone is exposed to such a problem in our lives. But as far as formaldehyde pollution is concerned, we must not remove it lightly, why do we say this? In fact, formaldehyde is a harmful substance, if it receives our human skin, it will definitely cause damage to the skin, and it will be necessary to stay indoors for a long time with formaldehyde seriously exceeding the standard, people will feel dizzy and vomit.

It is recommended to use plant-derived Quanshibang to remove formaldehyde, and decompose formaldehyde by adsorbing formaldehyde and chemically reacting with it. In normal times, open doors and windows to ventilate more, so that the air can be convection, and the formaldehyde can be removed and placed at home with Quanshibang, which is convenient and fast. Therefore, we must not be careless when solving the formaldehyde problem.

However, if it is found that there is excessive formaldehyde in the room, then it must be solved and removed in time. In this way, we can ensure that formaldehyde does not affect our health. Because only in this way can we move into the new house with peace of mind.

Safe and reliable, and more reassuring for our family.
