How to tell if there is formaldehyde in a newly renovated room

At present, there are formaldehyde detection boxes on major shopping malls, there are two kinds of instruments and test strips, test strips are only twenty or thirty yuan, and the instrument is about two or three hundred yuan. Although it cannot be said to be very accurate, it also has a certain reference role.

Hello! Newly renovated houses, taking into account the health of the occupants, in the case of paint and coatings on the walls and furniture at home, there will be a certain amount of formaldehyde content volatilization, you can use a formaldehyde detector to detect whether it exceeds the standard, or ask a professional indoor environmental assessment testing agency to test it is more appropriate!

If you want to accurately judge whether formaldehyde exceeds the standard, it is recommended to find a professional third-party testing agency for on-site testing.

You can hire a professional indoor air treatment company to test the formaldehyde content in the new house.

Indoor air treatment companies generally have more accurate instruments and effective detection methods, which can accurately detect the content of formaldehyde in the room.

Use formaldehyde detection instruments to determine whether the indoor formaldehyde content exceeds the standard.

First, the method of detecting formaldehyde in the collapsibility faction.

1. Formaldehyde self-test box.

Formaldehyde self-test box is the easiest and most objective formaldehyde detection method, and you can detect it without asking someone to do it yourself.

The formaldehyde self-test box is developed by the Chinese Academy of Inspection and Quarantine and developed according to the "phenol reagent colorimetric method" for formaldehyde detection and sampling according to the national standard. Therefore, from the principle of the formaldehyde self-test box, it not only has a scientific basis, but also conforms to the chemical inspection methods specified in the national standards.

Advantages of formaldehyde self-test box:

1. Cheap, simple to operate and easy to buy.

2. It can detect pollution release sources, which is more practical and scientific, and can accurately find indoor formaldehyde pollution release sources.

3. You can use the formaldehyde self-test box to verify the effect of formaldehyde removal products and monitor them for a long time to ensure the safety of the indoor air environment.

2. Professional testing unit.

There are two main types of professional Duanhe testing institutions: one is professional research institutions or business units under the management of **; The other type is private testing companies. Professional testing is multiple-point, multi-point testing.

Entrusting a professional testing agency needs to make an appointment in advance, take the air on site, bring it back to the laboratory for testing, and wait at least 2-3 working days for the results, which is relatively high. Theoretically, the test results are the most accurate, and only human factors such as on-site operation errors will affect the accuracy of the test results.

In addition, there is a type of formaldehyde detection instrument on the market - formaldehyde detector (formaldehyde speed tester), as long as you can buy it on a treasure, the first span is larger, but the current detection principle of formaldehyde speed tester is not in the national standard.

You can know whether there is formaldehyde in the new house through testing, use a test box or detector, or ask a special agency. Of course, the presence or absence of formaldehyde can also be judged by the body's reaction. Once symptoms such as chest tightness and headache appear, if the indoor plants quickly turn yellow and wilt, it can indicate that there is formaldehyde in the room, and the concentration is very high.

Among them, the most accurate method of detecting formaldehyde is a non-professional organization. Through accurate instruments, the indoor air is sampled and tested, so as to give a report on whether the space contains formaldehyde. This kind of detection can not only provide effective detection data, but also determine the treatment measures according to the situation, which is more efficient, but more costly.

If you have a limited budget, you can choose to purchase a test box or detector, where the test box is more commonly used. This method is quick and easy to operate, and the formaldehyde test results are given by different colors. Its main principle is to use the internal reagent to react with formaldehyde, thereby changing the color of the paper, and then judge the formaldehyde content according to the color card.

If the detection color is blue, it must not be occupied, and Zhixian Tangerine needs to immediately control the formaldehyde in the space. In addition, whether there is formaldehyde in the space can be judged by our body reactions. When we walked into the space, we suddenly felt dizzy, felt nauseous, and smelled a strong pungent smell, indicating that the space contained formaldehyde, and the concentration was still very high.

If this happens, the owner should leave the new home immediately and have it tested for formaldehyde. At the same time, if the owner places plants in the new house, it can also be used to determine whether formaldehyde exists, that is, if the plants quickly turn yellow and wilt within a period of time, it can indicate that the group space contains formaldehyde, which needs to be tested and treated to avoid affecting the human body.
