What is the best way to detect formaldehyde in new house decoration?

We all know that decorating a new house is a complicated matter, and there are many things to pay attention to. You can't move in immediately after the house is decorated, because it will contain a lot of formaldehyde, and it needs to be left for a while. So how do you judge whether the formaldehyde in the new house decoration exceeds the standard? Let's take a closer look!

Methods for detecting formaldehyde

Formaldehyde self-test kit

The formaldehyde self-test kit uses the principle that formaldehyde is easily soluble in water for detection. It is simple to operate and low-priced. However, the formaldehyde self-test kit is easily interfered by various external factors, resulting in inaccurate detection results.

Formaldehyde detector

The price of formaldehyde detectors ranges from a few hundred yuan to a few thousand yuan. They can not only detect formaldehyde content, but also detect other harmful gases. They are more convenient to operate, but the test results are mostly inaccurate and are for reference only.

Professional agency testing

You can find a company with CMA certification to conduct the testing. The testing is more professional and the results are accurate, but the price is relatively expensive. Moreover, many companies not only have formaldehyde testing services, but also formaldehyde removal services. Be sure to find a formal company to avoid being deceived.

Formaldehyde characteristics

If we want to remove formaldehyde, we must first understand the characteristics of formaldehyde and know the enemy directly, so that we can win every battle.

Formaldehyde smell

Formaldehyde is a gas without any odor, so you cannot judge whether the formaldehyde level exceeds the standard by smelling it. However, formaldehyde is irritating to a certain extent. When the formaldehyde level exceeds the standard seriously, it will irritate the human respiratory tract and eyes.

The relationship between formaldehyde and water

Formaldehyde is a gas that is easily soluble in water. The liquid formed by formaldehyde dissolved in water is the anti-corrosion paint formalin. However, formaldehyde will not actively react with water, so putting a basin of water in the room will not have the effect of removing formaldehyde.

The relationship between formaldehyde volatilization and temperature

There is a direct relationship between the volatilization rate of formaldehyde and temperature. The higher the temperature, the faster the formaldehyde evaporates, so summer is the season with the fastest formaldehyde volatilization in the year.

Methods for removing formaldehyde

Washing textiles

The raw materials used for curtains and sofa covers in the new house are generally cotton and linen. In order to prevent wrinkles and fading, adhesives are added, which contain a large amount of formaldehyde. You can use the relationship between formaldehyde and water to iron and wash all the textiles in the new house to remove the formaldehyde in one go.

ventilation

Ventilation is a convenient and reliable way to remove formaldehyde. Formaldehyde will only cause harm to the human body when it exceeds the standard. Opening windows for ventilation can reduce the formaldehyde content in the room, but it cannot speed up the volatilization rate of formaldehyde.

Green plants

All green plants need to carry out photosynthesis to grow, so green plants have a certain function of removing formaldehyde and releasing oxygen. However, the effect of removing formaldehyde is not very obvious, but it is better than nothing.

Activated carbon bag

Activated carbon bags have relatively strong adsorption capacity. They can not only absorb formaldehyde, but also remove odors. Activated carbon bags are generally placed in drawers and wardrobes that are not easily ventilated, and should be replaced regularly to prevent secondary pollution.
