Why formaldehyde in solid wood cabinets exceeds the standard?

The raw material of solid wood wardrobe is wood. In modern society, with the improvement of the quality of life, people gradually began to pursue a "green" home environment, so did furniture, and its "healthy and environmentally friendly" performance gradually became the focus of attention. Solid wood furniture is more and more loved and sought after by people, and when buying solid wood furniture, buying solid wood wardrobe is the most important thing. To know how to build a solid wood wardrobe, we must first figure out where we need it. Do you want to build a wardrobe in the porch to make your beautiful cloakroom? Or you need a big shoe cabinet, or you want to build a row of closet for your bedroom. You need to build a wardrobe according to the size of the wardrobe and the actual use you need. At the same time, you need to consider the whole space to determine the internal framework of the wardrobe. At the same time, if you put it on the porch, you'd better choose a sliding door to reduce the obstacles caused by opening the door. Only by carefully considering these things can we begin to prepare the wardrobe and provide it to us. ?

Formaldehyde, also known as ant aldehyde (HCHO molecular weight 30), is a colorless toxic substance with a particularly strong pungent smell, and is a low-grade aliphatic aldehyde. It is a gas at room temperature. Because there is no hydrogen bond association between formaldehyde molecules, the carbon atom SP2 in carbonyl group is hybridized, and the oxygen atom is not hybridized. The π-bond electron cloud in the carbon-oxygen double bond in the carbonyl group is biased towards the oxygen atom, and the carbon atom is positively charged, so the carbonyl group is easily soluble in water, and the highest solubility in water is 55%. 40% aqueous formaldehyde solution, also called formalin, has the property of solidifying protein, and is usually used to soak corpses and fix organ specimens. The boiling point of formaldehyde is very low, which is-19.5 degrees. It is volatile at room temperature, and the volatilization speed increases with the increase of temperature. If formaldehyde in the air exceeds the standard, the first organs to be violated are the eyes, mouth and nasal cavity with more water. The epithelial cell proteins of these organs are coagulated, denatured and necrotic, so there will be some symptoms of mucosal puncture. If exposed to formaldehyde for a long time, the epithelial cells of these rake-like organs will continue to necrosis and fall off, and the basal mucosa is prone to gene mutation and cancer in the process of hair growth supplement. Formaldehyde seriously damages the liver, kidney, nervous system and immune system in the process of metabolic elimination in vivo, causing some corresponding symptoms and signs.
