Formaldehyde has been identified as a class of carcinogens by the World Health Organization, which has great harm. The main sources of indoor formaldehyde pollution are furniture and fabrics, wood products fillers, detergents and personal products, among which the main ones are man-made panels, and the use of man-made panels in the bathroom belongs to the bathroom cabinet. At present, bathroom cabinets on the market are mainly divided into three kinds of substrates, including PVC (plastic), stainless steel and wood. Formaldehyde emission mainly occurs in wooden bathroom cabinets. Formaldehyde crisis is caused by the use of inferior adhesives or paints that do not meet the national testing standards, which seriously affects the health and safety of family members

formaldehyde has been identified as a class of carcinogens by the World Health Organization, which is harmful. The main sources of indoor formaldehyde pollution are furniture and fabrics, wood products fillers, detergents and personal products, among which the main ones are man-made panels, and the use of man-made panels in the bathroom belongs to the bathroom cabinet

at present, bathroom cabinets on the market are mainly divided into three kinds of substrates, including PVC (plastic), stainless steel and wood. Formaldehyde emission problems also mainly occur in wood bathroom cabinets. Formaldehyde crisis is caused by the use of inferior adhesives or paints that do not meet the national testing standards, which seriously affects the health and safety of family members. However, there are some misunderstandings in the evaluation of bathroom cabinet materials and the treatment of formaldehyde

myth 1: there is no great difference in the appearance between the bathroom cabinet made of MDF and multilayer plywood. It has high cost performance. It is the first material to buy the bathroom cabinet

correction: from the perspective of China's territory, there are places from south to north, from very wet to very dry, so we must choose robust plates. First, it should be able to withstand humidity and not easy to mildew. Second, it is hard enough to be damaged. The wood with the worst quality is particleboard, which is pressed from wood bran in the middle and adhered with log colored skin on the outside. In fact, this kind of material expands and breaks when it meets water and tide, and inferior glue volatilizes a large amount of fatal formaldehyde, which is seriously harmful to health. Better than particleboard is MDF, also known as high-density board. Because of its low cost, many manufacturers will choose it as the base material. But the final sequela is also water absorption and mildew, and even Auricularia. Another problem is that the hinge can't be tightened after being removed and reinstalled after being installed askew. The better one is solid wood, but solid wood will also have many problems. There is also a multi-layer plywood. The price of plywood ranges from 70-300 yuan, and those with a speed of more than 200 yuan will be more practical. During the compression process, the stress is reduced due to the crisscross between the boards, which is not easy to deform and crack

Myth 2: solid wood bathroom cabinets are high-end and easy to use. They are the best choice among so many varieties of bathroom cabinets

correction: generally, logs become solid wood after cooking. The wood enters the oven for drying, from 18 o'clock water of the log to below 8 o'clock. However, due to the humid climate in Guangdong, there is usually a humidity of 60-70 points. If the wood comes out of the drying room and is not immediately cooled by the wind and painted, it is easy to absorb water. Many small-scale factories can't paint the wood in time, and soon absorb water to 12-13 o'clock. In addition, the boards are spliced in the form of gears. If water enters the splice, it is easy to swell and burst

myth 3: we can rely on green plants, odor pills and activated carbon to adsorb formaldehyde

correction: if you want to adsorb formaldehyde, tea residue is actually the most effective, and the rest are clouds. However, it only absorbs formaldehyde instead of human body and cannot be diluted. The right way to drive away formaldehyde is to open windows to let the air circulate and take away formaldehyde. Generally, formaldehyde that slightly exceeds the standard can be released in about three months to a year under ventilation

myth 4: ordinary people have no way to detect formaldehyde content, only through formal national testing institutions or testing experts

correction: although ordinary consumers have no way to know the exact content of formaldehyde in the bathroom cabinet, they can smell formaldehyde through their nose. Open the closed cabinet and smell it closely. If there is a pungent smell, there must be formaldehyde, and the content is not low

myth 5: ordinary consumers don't need to know the formaldehyde emission level. Just open it and smell it without any pungent taste

correction: at present, some bathroom cabinets are marked: “ Zero formaldehyde ”, It's E0 grade, but it's difficult to achieve this, and it costs a high cost. Generally, it's good if the bathroom cabinet on the market can reach E1 grade. The formaldehyde content is very small, and the emission is almost negligible. Those exceeding E1 level can dissipate in three months to one year. Consumers had better ask the merchants to show the quality inspection certificate, because some unscrupulous merchants will use all kinds of scented products, such as perfume, candles, etc., and put them in the cabinet. Once opened, they will be covered by this smell
