Self-test case
Online shopping furniture exceeds the standard, serious shopping mall brand furniture is relatively normal
On June 22nd, Mr. Li, who lives in Xi'an Qujiang Ziwei Yijing Community, stayed in the new house for a few months. Recently, he felt that the scorpion always had a slight pain. He guessed whether it had a relationship with the formaldehyde content of the new house. So he purchased a gas detection alarm to test the various spaces in the home. He closed the door of the furniture for more than 2 hours and then tested it. The specification of the detector says that the formaldehyde concentration exceeds 0.1ppm, which is beyond the standard. After testing, the internal space detection value of the coffee table showed 1.79, the value of the bed was 1.6, the wardrobe and TV cabinet were all around 0.03, and the value of the shoe was 0.16. The coffee table and the bed are all bought online. The wardrobe, TV cabinet and shoe cabinet are all well-known brands customized in the mall. â€
The highest data is 17 times higher than the set standard! If you want to follow the national standard (0.06ppm), exceed the standard by nearly 30 times!
The data is terrible. So how do you remove aldehydes?
Source of formaldehyde
In addition to wood products and paint, there are curtains and bedding
According to Shang Jun, Minister of Complaints Department of Xi'an Residential Decoration Association, in order to protect the health of occupants, many countries have strict regulations on the concentration of formaldehyde in indoor air, for example, the United States: 0.10ppm; Germany: 0.10ppm Sweden: 0.13ppm. China also stipulates that the maximum allowable concentration of formaldehyde in indoor air shall not exceed 0.08 mg/m3 (approximately equal to 0.06 ppm).
Indoor formaldehyde mainly exists in wooden furniture, wooden building materials, paints, wallpapers, textiles, and the like.
Prevention
After the charcoal bag is full, it will release formaldehyde ventilation.
â—The window is often ventilated, and the formaldehyde is not recommended. ☆☆☆☆☆
Formaldehyde is released from the furniture and building materials into the air, which may cause harm to people's health. Avoiding it hurting people is to drive it outside, and the window ventilation is simple and fast.
It is recommended to open the doors and windows frequently when weather conditions permit, to achieve uninterrupted air convection. If there is no one in the house or the weather is bad, it is recommended to open the home's fresh air system, change the fan or change the fan, and also achieve air convection.
◠Charcoal package, after the full, will release the formaldehyde recommendation index ☆ ☆ ☆ ☆
Charcoal, bamboo charcoal, and activated carbon cannot remove or decompose formaldehyde, and only adsorb formaldehyde. The pores inside these carbon products can effectively adsorb free formaldehyde molecules in the air, and cannot be driven away, and the adsorption is temporary.
Tsinghua University's Building Environmental Testing Center has conducted an experiment to prove that bamboo charcoal even releases formaldehyde after it is filled with formaldehyde. Experts explained that this is a kind of dynamic balance, and the adsorption and desorption reach equilibrium when the concentration temperature is determined. When the concentration is lowered outside, the balance is broken and the adsorbed matter is released. It is recommended that after placing the charcoal bag placed in the room for a period of time, it should be placed in the outdoor air to release the formaldehyde and then used.
â—Green plant, slow formaldehyde absorption recommendation index ☆☆☆
Many green plants can absorb formaldehyde, but this is only a self-defense reaction of plants (because formaldehyde is also harmful to plants, plants can be "detoxified"), and only a small amount of formaldehyde around the leaves can be removed. It is recommended to place more broad-leaved green plants to increase the "combat" area of ​​the plants.
â—In addition to aldehyde products, it is difficult to judge the recommended index ☆☆
Everyone saw "formaldehyde decomposition liquid", "formaldehyde scavenger" and other products on the Internet. The main propaganda function of this type of product is that the surface of the furniture can be used to decompose formaldehyde or accelerate the release of formaldehyde from the furniture. However, there is no industry-mandated standard for such products in the country, and the quality and efficacy of specific products are difficult to determine.
Consumers can use it in combination with other methods of removing formaldehyde. Huashang Daily reporter Li Zhenyong
Custom cabinet
90% of people will make mistakes
Before custom cabinets, everyone usually goes to the exhibition hall to see the sample cabinet.
It is estimated that many people will focus on the style, color and hardware of the cabinet. And whether the cabinet is environmentally friendly, functional, and after-sales service... these key issues are always ignored.
Huashang Daily reporter visited Duplo Dizzini, Ou Pai, Haier cabinets and so on to learn that 90% of consumer custom cabinets will make some mistakes.
Error 1
Simply pursuing style neglects the functionality of the cabinet
Case: Ms. Jin's custom cabinets are mainly to see if the color of the cabinet matches the overall style. She believes that the color of the cabinet affects the mood of the cook, and the style highlights the owner's taste. Later, I found that the cabinet did not have a basket, there were few hanging cabinets, and the storage space was not enough.
Reminder: Ms. Zhang, the sales of Duplo Dizany, said that the purchase of cabinets needs to be a perfect combination of practical, beautiful and functional. Designers need to design cabinet styles based on the size and space of the room, and consider whether to match the home improvement style, but also consider the number of family members, age and height to ensure the safety of the cabinet.
Consumers should not blindly pursue aesthetics when purchasing. If there are more kitchen utensils in their homes, they can suggest that designers add more cabinets or drawers when customizing. The functionality is an important consideration for cabinet customization.
Error 2
Moisture proof is waterproof sheet, environmental protection is cabinet environmental protection
Case: Mr. Lin, who lives in Huayuanhai Blue City, bought a moisture-proof environmentally friendly cabinet at the store two years ago. In March of this year, Mr. Lin’s kitchen sink leaked, and when it was discovered, the wooden boards behind the sink were deformed. How is the moisture-proof sheet not waterproof?
Reminder: The reporter visited the Beiming Ming Palace cabinet area and learned that many shopping guides introduced the cabinet materials to prevent moisture, environmental protection and fire prevention. Many consumers think that moisture is waterproof.
Wang Jiantao, chairman of Boao Card cabinets, said that the moisture-proof performance of the board means that the board can be specially treated to prevent moisture intrusion in the air. However, any sheet is not waterproof. The environmental protection of the sheet reduces the formaldehyde content in the sheet to a level acceptable to the human body, and the body can be immune to no damage. However, the cabinet is a whole. In addition to the panels, cabinets, countertops, door panels, etc., the environmental protection of the panels is not equal to the environmental protection of the whole cabinet.
Error 3
The whole cabinet will not be damaged for a short time.
Case: Mr. Zhou, who lives in the northern suburbs, said: "When you buy a cabinet, you feel that such a solid thing can't be used for ten or eight years. I didn't expect it to be used for more than three years."
Reminder: Many consumers will not ask for the warranty period when customizing the cabinet, and will not ask for the warranty range in detail. Many merchants will generally inform consumers of “warranty for ten or five yearsâ€. Consumers should inquire about the warranty period of each part when purchasing, such as countertops, hardware, cabinets, hoods and so on.
Warranty maintenance reflects the credibility of the brand to a certain extent. When consumers choose, they should try to inspect the powerful cabinet brands. These brands have certain reputation and management strength, and they also have a complete system in after-sales service. At the same time, in the formal store to buy furniture, building materials, pay attention to retain the store shopping invoices and receipts.
