In recent years, as consumers have higher and higher requirements for home furnishing quality, solid wood furniture has gradually become a popular furniture material for its solidity, durability, beauty, and environmental protection. However, during the purchase and use process, consumers will also have doubts about the smell of solid wood furniture: many people know that furniture contains formaldehyde, but does solid wood furniture also contain formaldehyde? Does the smell of solid wood furniture exceed the formaldehyde standard?

How does the smell of solid wood furniture come about?

To understand the issue of "smell" and "excessive formaldehyde" in solid wood furniture, we must first talk about the source of the "smell" of solid wood furniture.

One is the smell of the solid wood itself. According to a senior person who has been engaged in the home furnishing industry for many years, "as long as it is log, it will definitely have a smell." At present, there are many types of logs used in solid wood furniture on the market, including North American oak, black walnut, cherry, ash, etc., which are all popular mid-to-high-end hardwoods on the market and are highly recognized.

Each type of wood has its own unique smell. For example, redwood has a fragrant, sandalwood smell; pine has a resinous smell; cypress has a cypress aroma; poplar has a grassy smell; red oak has a sour smell, etc. Take North American oak, which is used in large quantities, for example. Because it contains tannins, it has a sour smell. This smell will exist as long as the logs are processed. After ventilation for a period of time, the surface smell will gradually fade.

The second is the smell of coating and glue. The logs need to be processed into furniture, and the surface needs to be beautified with coating. The most commonly used oil-based paint has a smell mainly from volatile organic compounds (VOCs) in organic solvents, such as benzene, toluene, xylene, styrene, trichloroethylene, trichloromethane, trichloroethane, diisocyanate (TDI), diisocyanatotoluene, etc. When the concentration reaches a certain level, there will be a noticeable smell.

The smell of water-based paint mainly comes from water-soluble resin, which is the smell of acrylic acid. The wood wax oil applied on the surface of solid wood furniture is a coating method that uses plant wax such as palm wax as a film-forming material and plant oil such as linseed oil as a solvent, and there will also be some smell. However, no matter what kind of coating, as long as it is a product purchased from a regular big brand, there is no need to worry too much about environmental issues. The solvent will gradually evaporate and the smell will weaken.

Glue itself also has a smell, which also comes from volatile organic compounds. Solid wood furniture generally uses a small amount of glue in several places, such as mortise and tenon joints, wood bites when using large board direct splicing technology, veneer of veneered solid wood, wood joints of finger-jointed boards, etc. Now, except for some small furniture workshops that use urea-formaldehyde resin adhesives with formaldehyde as raw material to reduce costs, regular large factories and brand companies have generally adopted MDI glue without formaldehyde addition, which meets the standards and does not need to worry about formaldehyde exceeding the standard.

Generally speaking, VOCs have a volatilization cycle, and most VOCs have been volatilized during the production process. If there is still an odor after you buy it home, as long as you keep it ventilated, it will evaporate and the odor will be significantly reduced.

Does the presence of smell mean that formaldehyde exceeds the standard?

After understanding the source of the smell of solid wood furniture, let’s talk about "formaldehyde".

First of all, "formaldehyde" cannot be identified by "smell". Formaldehyde is a colorless, irritating gas. It has no characteristic smell, so it is difficult to judge whether there is formaldehyde by smell. The intuitive feeling of high concentration of formaldehyde is stinging eyes, sore throat, nausea and headache.

Secondly, "formaldehyde" is everywhere, and formaldehyde controlled within certain parameters is harmless to the human body. In this sense, the logs used to process solid wood furniture also contain trace amounts of formaldehyde, but there is no need to worry, because it does not reach a certain concentration. As long as the "formaldehyde" does not exceed the standard and meets the national standards, it is relatively harmless to the human body. In the national standard "Grading of Formaldehyde Emissions of Artificial Boards and Their Products", the ENF grade (≤0.025mg/m³) is currently a relatively strict standard in China.

When buying household products, you should first understand the brand and environmental parameters

Compared with the price, solid wood furniture is indeed more expensive than furniture made of composite boards, plywood, spliced ​​boards and other boards. Many consumers choose solid wood furniture from the perspective of environmental protection with the mentality of "spending money to buy health". However, it is not ruled out that there are sales under the guise of solid wood furniture. Therefore, it is recommended that consumers first understand the product brand and environmental protection parameters before purchasing home furnishing products, and check the product inspection and testing reports, and try to choose those brand companies with strong strength and good reputation to avoid being deceived.

In recent years, many brands have emerged, and they are deeply trusted and favored by the public in terms of product quality, price, and after-sales service. For example, Genji Wood Language, a representative enterprise in the solid wood furniture industry, always insists on 100% pure solid wood in terms of raw material quality, and chooses safe, environmentally friendly, and vital North American and European FAS-grade hardwood.

Secondly, in terms of safety and environmental protection, the paint used by Genji Wood Language is also an odorless paint developed by the Hezhanchen Environmental Paint Laboratory, which is very environmentally friendly.

In addition, in terms of customer service, Genji Muyu promises "90-day return and exchange, 8-year warranty, and lifetime service", and improves consumers' shopping experience from the entire chain of "pre-sales", "sales" and "after-sales", and optimizes the after-sales service system.

Household products are related to daily health. When purchasing, you can look for big brands with quality and after-sales guarantee, so that you can buy with confidence and use comfortably.
