After the renovation of home, the addition of aldehyde has become an indispensable part of the stay. In addition to the different aldehyde methods, which is the most effective, what kind of materials or appliances can be selected to solve indoor formaldehyde problems at the fastest? Let's come today Compare one by one.

How much is the formaldehyde hazard?

National standard content 0.08mg/m3

The critical value of indoor formaldehyde content in the national standard is 0.08 mg/m3, that is, the indoor formaldehyde concentration before the completion of the renovation needs to fall below 0.08. The indoor formaldehyde content exceeding the standard will cause respiratory discomfort, persistent cough and even bronchitis, and physical injury. great.

Nearly 60% of new homes have excess formaldehyde

According to the survey data, among the newly renovated houses, 60% of the families had problems with unqualified air quality, among which the formaldehyde content exceeded the maximum, followed by ammonia exceeding the standard, TVOC exceeding the standard, and exceeding the benzene content. The unqualified household formaldehyde content generally exceeds 0.1 mg/m3.

Choose formaldehyde to detect less than 30% of households

Although the problem of formaldehyde content exceeding the standard after the renovation was widespread, there were less than 30% of households that chose to ask professionals to check or purchase simple instruments for inspection. Most people had some neglect of formaldehyde hazards and believed that there was no odor at home. No formaldehyde.

Formaldehyde residue can reach 8-10 years

The volatilization of formaldehyde is a slow process. The interior decoration just after the end of the ventilation can evaporate most of the indoor formaldehyde. However, the interior of the building materials such as floors and cabinets is slow to volatilize, and sometimes it can last for more than 10 years. Helps volatilize through other external forces.

Common aldehyde analysis

Natural ventilation promotes volatilization

Ventilation and planting green plants is the simplest method of removing aldehydes. It is especially suitable for the early stage of renovation. This method generally takes a long time. The room needs to be vacant for 1-2 months before it can be basically removed. At the same time, the formaldehyde in building materials cannot Intensive removal, plants rely mainly on adsorption method to clear, but the slowest.

Deep porous material adsorption

Many families choose to place activated carbon at home is a typical natural adsorption method, through the adsorption of porous substances, the free formaldehyde molecules in the air fixed to the adsorbent, in addition to activated carbon, grapefruit skin, plants and so have adsorption, but This type of adsorption is generally inefficient and requires a large amount.

Strong oxidative decomposition of formaldehyde

Photocatalyst is the most common class of formaldehyde decomposing substances. It was used in cars in the past. Many families now choose to spray photocatalysts directly on the walls. It can produce strong catalytic degradation under light and effectively decompose formaldehyde and other harmful gases. At the same time also has anti-fouling, deodorant, air purification and other functions.

In addition to the aldehyde machine to quickly clean the air

In addition to the aldehyde machine is a class of home appliances developed specifically for indoor formaldehyde purification, similar to the purifier, but the key role of different principles, such as Haier aldehyde removal machine, through the nano-aldehyde lock particles and cold catalyst decomposition principle, in the purification of air and efficient adsorption of formaldehyde At the same time, it will be rapidly decomposed and quickly complete indoor formaldehyde purification.

Indoor common formaldehyde source

Wall paint

Formaldehyde is an essential component of the coating. To avoid strong formaldehyde stimuli, it is best to choose a regular brand of odorless paint or a low-VOC product.

Cabinet furniture

The material of solid wood panels is natural, and the content of formaldehyde is the lowest, while the panels of density boards, medium-density fibre boards, etc., use more glue, and the content of formaldehyde is high.

Flooring timber

The formaldehyde content of the flat composite floor is much higher than that of the solid wood floor.

Decoration Accessories

In addition to building materials, there are also a large amount of formaldehyde in the decoration accessories, such as glass glue, white latex, and floor glue.

Soft cloth

For fabrics such as curtains and sofa covers, there is a certain amount of residual formaldehyde in the newly made fabric, so it can also smell a noticeable odor.
