How to judge whether furniture contains formaldehyde? Where does formaldehyde usually exist in furniture?

We all know that furniture is an indispensable part of the home. Almost everyone will buy furniture when decorating their house. There are many types of furniture on the market, and the quality is also different. Some are of better quality, some are of worse quality, and they contain more formaldehyde. So how do you determine whether furniture contains formaldehyde? Let's take a closer look!

How to determine whether furniture contains formaldehyde

1. Mortise and tenon structure

It is difficult to directly detect whether furniture contains formaldehyde, but it can be judged by the places where formaldehyde exists mentioned above. If the mortise and tenon structure adopted by the furniture does not use glue, then at least the glue is more environmentally friendly.

2. Materials

If the furniture you buy is made of artificial boards, it will inevitably contain formaldehyde. Therefore, when buying furniture, you must confirm the material of the furniture you buy. Solid wood furniture is more environmentally friendly in terms of materials.

3. Paint

In today's furniture production, oil-based paints generally contain formaldehyde, so now, many furniture uses water-based paints, which are more environmentally friendly.

Does furniture generally contain formaldehyde?

In fact, for the general public, we do not have any professional testing methods to detect whether furniture contains formaldehyde, or it is difficult to determine the exact value of its release. We can only judge whether formaldehyde exists based on some basic characteristics of formaldehyde.

1. There is no doubt that all furniture uses substances containing formaldehyde in the production process to a greater or lesser extent. So there is no need to guess or judge. New furniture that has just been manufactured or just purchased will contain formaldehyde.

2. The dumbest method. It is well known that formaldehyde has a strong irritating smell. When purchasing furniture, if you open the door or drawer of the wardrobe and feel a pungent smell, it means that this piece of furniture not only contains formaldehyde but also the release amount must exceed the standard.

3. For soft furniture, put your nose close to the surface of the furniture. If you can sense an odor, it means there is formaldehyde present.

Recommendation: When consumers are shopping for furniture, it is best to go to the furniture store in the afternoon. This time period is the best time to determine whether the formaldehyde content of the furniture exceeds the standard, because all furniture stores will open all the door panels, drawers, boxes, etc. of the furniture when they get off work in the evening. If you go in the morning, you won't smell anything. If you go in the afternoon, the interior space of the furniture that has been stuffy all day will give you an answer.

Where formaldehyde exists in furniture

To determine whether furniture contains formaldehyde, we first need to understand where the formaldehyde is in the furniture.

glue

Nowadays, glue is used for bonding in the production of furniture. The name of the glue is urea-formaldehyde resin, which is mainly produced by urea and formaldehyde under the action of a catalyst. Therefore, the glue contains a large amount of formaldehyde, and the formaldehyde is hidden deep in the furniture and has a long volatilization period.

Artificial board

Artificial boards are used in furniture production today. The most common ones are density boards and particle boards. Urea-formaldehyde resin glue is used in the production of both types of boards, and there is also a large amount of glue.

paint

The paint on the surface of furniture also contains formaldehyde, but the formaldehyde on the surface of furniture evaporates very quickly. The formaldehyde in the paint can be evaporated away by ventilation for a period of time.

Textile

In order to prevent wrinkles and fading, adhesives are added to sofa cushions and sofa covers during production, and the adhesives contain a large amount of formaldehyde.
