[ Chinese wardrobe net ] The volatilization of formaldehyde is closely related to temperature. In general, the higher the temperature, the more likely the formaldehyde in the furniture will evaporate. According to experts, the hot summer season is the most “manic” season for formaldehyde volatilization: for every 1 °C rise in room temperature, formaldehyde volatilized at wooden furniture and flooring will increase the concentration of formaldehyde in indoor air by 0.15-0.37 times. If the formaldehyde content of the furniture set by the consumer is not up to standard, it is easy to release formaldehyde in the summer.

I believe that many owners of decoration have long been aware of the dangers of formaldehyde. The main hazard of formaldehyde is the stimulating effect on the skin and mucous membranes. As a colorless and irritating gas, formaldehyde is very harmful to the human body. Excessive levels of formaldehyde in the air can cause dizziness, nausea, vomiting, and red spots on the skin. Living in such an environment for a long time may cause various chronic diseases and even cancer.

Secret 1: The source of formaldehyde in the bedroom

The wardrobe is the largest piece of furniture in the bedroom. In the bedroom, the main source of formaldehyde is the wardrobe. This is because the air pollutants such as formaldehyde in the living room are mainly derived from various furniture, plates and various adhesives using composite wood as a base material. Therefore, the amount of formaldehyde in the wardrobe sheet is directly related to air pollution in the bedroom.

Plate is the main component of furniture products, its quality directly determines the quality of the product and the price of the product. The plates are divided into solid wood panels and artificial panels. The solid wood board is sturdy and durable, with natural lines and low formaldehyde emission. Most of them have the unique aroma of natural wood. The wood-based panel is inevitably released with a certain amount of formaldehyde because it is a molded product obtained by using wood or other non-wood plants as a raw material by using an adhesive or an additive.

However, under normal circumstances, due to the high cost of solid wood panels, ordinary custom-made wardrobes are basically made of wood-based panels, so formaldehyde is basically more or less present in the home space.

Plate knowledge: According to China's environmental protection standards, according to the concept of formaldehyde emission limit, the formaldehyde limit level in the board is divided into three levels, E2≤5.0mg/L, E1≤1.5mg/L, E0≤0.5mg/L. In China, plates can reach the E2 standard, and E2, E1 and E0 plates can be called environmentally friendly plates.

Secret 2: The barrier of formaldehyde - the edge of the wardrobe sheet

Due to the relatively high cost of solid wood panels, in general, most consumers choose wood-based panels for the manufacture of substrates, then the environmental protection of the wardrobe is particularly important.

The function of the edge of the wardrobe is to seal the cutting section and prevent the sheet from releasing formaldehyde. In order to save production costs, many manufacturers of wardrobe production have not sealed all the edges of the panels, resulting in more formaldehyde pollution.

Currently on the market there are 0.4mm, 1mm, 1.5mm and 2mm. A too thin edge banding has a poor hand feel, and a thick edge banding and a gap at the edge banding are large. In general, the optimum thickness of the edge band is 1.5 mm. At the same time, edge sealing glue is also a factor that affects the overall beauty and environmental protection of the wardrobe. Many brands in the market will stamp their own brand logo on the edge of the seal as a sign to ensure the quality of the brand.

The edge sealing process of the wardrobe is good or bad, and the quality and service life of the wardrobe itself are the key to affecting the environmental performance of the wardrobe. The key to the edge-sealing process is the three points of edge banding machine, edge banding and edge banding. However, it is difficult for us to know whether the wardrobe is good or bad by observing the edge banding machine and the edge banding glue. Then, how to identify the wardrobe edge banding?

The high-quality edge banding must be firm enough, it is aging, not easy to crack. Nowadays, in many wardrobe manufacturers, the same color edge banding is often used, that is, the color of the edge banding is consistent with the color of the cabinet. The edge banding must be polished and rounded to make the touch feel better. At this time we can know that the edge band is good or bad.

Inferior edge banding, the color of the cut surface after polishing is white, and it can not maintain the color consistent with the surface of the edge banding. This edge band is easy to age and crack. For high-quality edge banding, the polished face is often consistent with the surface color.

Secret 3: Beware of four major details of formaldehyde release

The emission of formaldehyde in the closet is a very slow process. The melting of a new home is 3 to 4 years after the renovation. The formaldehyde pollution is the most serious during the 4 to 6 months of the renovated house, and the time of formaldehyde damage The length is determined by the objective conditions, that is, according to how much wooden furniture is in the house and what kind of paint is used.

Choose a strong brand wardrobe

The furniture wardrobe industry is booming and the market is not mature enough, so there are still many problems in the industry. For example, the plate is sub-filled, the plate formaldehyde is seriously exceeded, and the quality is poor.

The period of formaldehyde volatilization can reach 3-15 years. If the custom furniture exceeds the standard, the situation is very serious. The effects of ventilation and adsorption are limited, and the problem cannot be solved fundamentally. Except that formaldehyde is only a temporary solution. The best way is to choose the large, well-known whole wardrobe manufacturers custom furniture, product quality is guaranteed, relatively healthy and environmentally friendly.

Carefully purchase wardrobe surface decoration materials

The sealing effect of the surface of the wardrobe on formaldehyde is very obvious. In the specific implementation process, attention should be paid to the use of low formaldehyde release adhesives, various decorative materials and coatings, and reasonable processes to ensure that no new formaldehyde is released after decoration.

Reduce the number of furniture placed indoors

The higher the load factor, the higher the formaldehyde concentration. The so-called load ratio refers to the ratio of the surface area exposed to the air in the indoor furniture closet to the indoor volume. Therefore, in the case that the function is basically satisfied, the number of pieces of furniture in the indoor space should be minimized, thereby reducing the emission of formaldehyde in the furniture.

Release furniture formaldehyde in advance

Temperature, humidity, and ventilation all affect formaldehyde emissions. Under normal climatic conditions, the temperature will increase by 8 ° C, the concentration of formaldehyde in the air will double; the humidity will increase by 12%, and the amount of formaldehyde will increase by about 15%. Therefore, under the premise of conditions, air conditioning and fresh air system devices can be used to adjust the indoor temperature and humidity and fresh air volume, so that formaldehyde emission is moderately controlled.

The formaldehyde emission concentration of the furniture is proportional to the post-production release time. It should be placed for a period of time before use, and placed in a high temperature and high humidity environment during the discharge, to accelerate the emission of formaldehyde to reduce the pollution in the future use.
