What should I do if the formaldehyde is detected indoors?

Greini's air catalyst removes formaldehyde and has a good effect.

Dear, hello, you can detect whether indoor formaldehyde exceeds the standard by the following two methods:1Formaldehyde detector:

It is possible to detect indoor formaldehyde concentration by renting or purchasing formaldehyde detection instruments, which is a more direct and accurate method. You can place the formaldehyde detection instrument in the indoor environment that needs to be detected, wait for a period of time to get the formaldehyde concentration value, and judge whether it exceeds the standard according to the national standard. 2.

Chemical reagent method: This method requires sampling in a room to detect formaldehyde concentrations by using chemical reagents. Posture grinding usually needs to be sampled in room air, and after the reaction with the reagent, the formaldehyde concentration is judged according to the degree of discoloration.

It is important to note that regardless of the method used, the environment should be kept closed during the test to avoid air circulation affecting the test results. If formaldehyde is found to be exceeded, corresponding measures should be taken to treat it, such as opening windows for ventilation, using formaldehyde scavengers, etc.

The method of detecting indoor formaldehyde is as follows:

1. Use a formaldehyde detector.

Formal qualified formaldehyde meter** is very expensive, and it is not cost-effective to buy a house for testing. At this time, you can hire a professional testing company, and there is also a professional management company, which is also more expensive, and you can choose according to your actual economic situation.

2. Smell the smell.

Indoor formaldehyde is smelly, the concentration of the Hui to a certain extent, can be smelled, if you can clearly smell the room banquet answer there is a peculiar smell of decoration, indicating that formaldehyde is exceeded, this is a serious exceedance.

3. Observe the growth of plants.

After the decoration of the new house, I believe that many friends will prepare a lot of plants to remove formaldehyde, such as spider plant, pothos, tiger piran and so on. This is when we can observe the growth of these plants. If there is a large area of withering, yellowing or sickness, etc., it means that the indoor formaldehyde has exceeded the standard.

4. Chemical testing.

It is relatively simple to use a portable formaldehyde self-test box, which is still a reference in measurement. With this simple method, the results will be biased greatly, so it is best to prepare more checkboxes and find the average.

5. Human reaction.

After moving into the new house, if the human body has obvious sensations in a short period of time, such as harsh eyes, coughing, etc., we should consider excessive formaldehyde.

Kiss, to detect whether indoor formaldehyde exceeds the standard, you can use the following methods:1Purchase air quality testing instruments for testing.

There are many detection instruments on the market that can locate and measure indoor CO2, TVOC and other air indicators with the help of highly sensitive cracking sensors, which can be used to detect whether formaldehyde exceeds the standard. 2.An air sample is collected and sent to a professional laboratory for testing.

Some air samples can be collected for further testing and detection by industrial-grade laboratory equipment, which usually requires high-precision analysis of the concentration of formaldehyde in the air, which is relatively complex and laborious and time-consuming.

Indoor formaldehyde is one of the common pollutants in home decoration, and if it exceeds the standard, it will have adverse effects on human health. The following are several ways to detect indoor formaldehyde exceeding the standard:1

Air detection method: Indoor air samples are collected through an air sampler, and the indoor formaldehyde concentration is detected by a professional laboratory. 2.

Test strip method: After exposing the test strip to indoor air for a period of time, judge whether the indoor formaldehyde exceeds the standard according to the color change of the paper. The dipstick test results are not accurate but can be used as initial screening.

3.Electrochemical sensor method: install electrochemical sensor equipment to monitor the formaldehyde content in the indoor air, if it exceeds the standard value, it will send out an alarm sound or display a digital prompt, so as to deal with it in time.

4.Light absorption method: the use of spectroscopic instruments to measure the concentration of formaldehyde in indoor air, this method has high accuracy, but requires professional operation.

It should be noted that different countries and regions have different standards for indoor formaldehyde, and the specific formaldehyde concentration standards should be tested and evaluated according to relevant local regulations. If the test results show that the standard is exceeded, measures should be taken in time, such as increasing ventilation, cleaning, etc., or using professional formaldehyde treatment equipment for treatment.

Dear, hello, to detect whether indoor formaldehyde exceeds the standard, you can generally guess the structure of a professional air detector or buy an air detector by yourself. Method 1: Ask a professional organization to conduct the test 1

3.Before testing, the room's doors and windows, air purifiers, and other equipment should be closed, and the use of any volatile substances should be stopped. 4.

The inspector will place the testing instrument in the room and measure the formaldehyde and other pollutants in the air for a certain period of time. 5.After the institution issues a test report, judge whether the indoor formaldehyde exceeds the standard according to the report data.

Method 2: Buy your own air detection instrument 1Purchase a professional air detection instrument and install and debug it according to the instructions.

2.Before testing, the room's doors and windows, air purifiers, and other equipment should be closed, and the use of any volatile substances should be stopped. 3.

Place the test instrument in the room** position and perform stabilization operation. 4.After a certain period of time, the detection instrument will automatically measure formaldehyde and other pollutants in the air.

5.After the test is completed, judge whether the indoor formaldehyde exceeds the standard according to the data displayed by the instrument. Whether it is method 1 or method 2, it is necessary to carefully review the relevant instructions and precautions before measuring, and carry out the preparation and testing operation according to the requirements.
