The main source of indoor formaldehyde is urea-formaldehyde resin, which is a kind of adhesive and is limited by the current industrial level and material cost. This is the most widely used adhesive component in home decoration and furniture manufacturing. Urea-formaldehyde resin will age and decompose under certain temperature and humidity conditions, producing formaldehyde and releasing it into the air, thus causing indoor formaldehyde pollution, which will often continue to be released for many years. Rumor 1: Plants in in addition to formaldehyde: Under the action of sunlight, green plants can absorb carbon dioxide and produce oxygen in the air, thus achieving the effect of refreshing the air. This leads people to mistakenly think that plants can also remove formaldehyde. Green plants can absorb carbon dioxide in the air under the action of sunlight, produce oxygen, and achieve the effect of fresh air. This will also lead people to mistake plants for removing formaldehyde. In fact, formaldehyde reacts with plant protein, nucleic acids and lipids, damaging plant cells and causing serious plant death. In an environment containing a lot of formaldehyde, it is still difficult for plants to protect themselves, let alone help humans remove formaldehyde. Proverbs 2: Removing formaldehyde with aged vinegar is a popular method to remove formaldehyde with vinegar: It is said that vinegar can react with formaldehyde. Is this true? Whether it is vinegar or white vinegar, their main component is acetic acid. Unfortunately, acetic acid does not react with formaldehyde, because vinegar has a strong pungent sour taste, which can hide the taste of formaldehyde, so people mistakenly think it is vinegar. Formaldehyde removal, in fact, formaldehyde has not decreased, still exists in indoor air, but its taste is hidden and more difficult to find. Proverbs 3: Pomelo skin and pineapple skin in addition to formaldehyde: In addition to grapefruit skin and pineapple skin, they all have their own unique fruit aroma, which is rich and lasting and refreshing. In fact, folk rumors say that they can eliminate formaldehyde just like vinegar. Grapefruit peel and pineapple peel do not remove formaldehyde. They only use their own smell to hide the smell of formaldehyde. However, although grapefruit peel can&;t remove formaldehyde, it has the effect of fresh air and mosquito prevention, so it is good to put a piece of grapefruit peel at ordinary times. Rumor 4 Activated Carbon in addition to formaldehyde In May 2014, CCTV Finance tested seven popular activated carbon products and found that the main components of seven brand products were carbonized materials, not activated carbon. The seven kinds of activated carbon products tested are all purchased through online purchase channels, and they are all top brands in sales. After testing these products, it is found that they are all unqualified, and the so-called &”;activated carbon&”; by the seller is mostly carbonized materials, which is not called activated carbon at all. Because the adsorption capacity of activated carbon itself is limited, and the seller uses activated carbon to simulate activated carbon, the consumption after using a lot of activated carbon cannot feel this effect, which is the reason. It seems that consumers who want to live in a new house early can&;t rely on activated carbon to solve the problem. Myth 5: Outside in addition to formaldehyde, decoration pollution is almost everywhere after six months of ventilation. In order to avoid it as much as possible, the general residential decoration will be reserved for about half a year before entering, and the workshop is spreading various tips to prevent decoration pollution. Are these rumors true? Although the number is small, some people still think that there is no smell and pollution in the room. In fact, some pollutants are colorless.Odorless, such as radon. Although formaldehyde has an irritating smell, generally speaking, if the content exceeds 2-3 times, people will not smell the obvious smell, or some other smells in life can easily cover it up. When formaldehyde is rampant, most people will choose to go out for a while after renovation, and then move in. However, ordinary family windows are designed at a place more than one meter above the ground, and the concentration of formaldehyde is higher than that of air, which is easy to precipitate. Even if the windows are ventilated, it is still difficult to completely remove formaldehyde. In addition, the release of most harmful substances is slow, as long as 3 to 15 years, and it is not solved by ventilation within a few months. High temperature weather in summer and heating period in winter are the peak periods of formaldehyde release, which is 20% ~ 30% higher than usual. Therefore, if the formaldehyde in the house exceeds the standard, it is useless to ventilate for several months. The key is to ensure that pollutants do not exceed the standard and indoor air quality is qualified. Before moving in, we must find a professional formaldehyde removal company for formaldehyde detection and treatment. Only when formaldehyde reaches the national standard value can we settle down.
