How to get formaldehyde in the wardrobe formaldehyde volatilization secret?
[ Chinese wardrobe net ] The volatilization of formaldehyde is closely related to temperature. According to Xiaohuan of China Wardrobe Network , in general, the higher the temperature, the more likely the formaldehyde in the furniture will evaporate. If the formaldehyde content of the furniture is not up to standard, it is easy to release formaldehyde in the summer.
The relationship between the volatilization of formaldehyde and the temperature is generally close. Generally speaking, the higher the temperature, the more likely the formaldehyde in the furniture will volatilize.
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.
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. It is worth mentioning that E2 will be cancelled in the new standard of 2018.
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.
