How do you all test the formaldehyde content in the house?

For the newly renovated house, the formaldehyde content is relatively high, so if we want to move into the new house after the renovation of the new house, it is easy to cause great harm to the body. So how do we detect formaldehyde in our newly renovated houses? And how to remove formaldehyde correctly?

It is estimated that many people are in the stage of confusion and don't know how to start!

There are several methods for detecting formaldehyde, what methods do you use to detect indoor formaldehyde?

The first is the self-test method: if the family members move into the new house and find that they are always dizzy and uncomfortable, or the children are always unenergetic and have a sense of powerlessness. And it will be better after opening the window for ventilation, so it must be a phenomenon of excessive formaldehyde.

In this case, it is necessary not only to send the hospital for examination, but also to open the windows for ventilation. In fact, the first method is also the stupidest method.

Secondly, formaldehyde meter detection, formaldehyde meter has a lot, including a treasure There are also many products, but there are many, buy back a machine, what to do if you can't test the desired results for half a day. If there is no formaldehyde measured at home, it is okay, at most it takes a little trouble, but if there is a formaldehyde measurement that is qualified, it will be difficult to do. Therefore, you must be cautious when choosing a formaldehyde meter.

For formaldehyde, many people will use items to absorb formaldehyde, including activated carbon, diatom mud, green plants, etc. It is more suitable for removing formaldehyde on the wall or ground, but because the amount is relatively small and the density is not high, the effect of removing formaldehyde is not very strong.

And it should be noted that when using the physical adsorption method, we need to replace them regularly, because they have no adsorption effect for a long time, and even some formaldehyde gas will be released after saturation.

However, no matter how powerful formaldehyde is, it is still a gas after all, and the best way to volatilize the gas as soon as possible is to open the window for ventilation. As a result, many people now move in after ventilating their houses for a while. In terms of ventilation time, of course, the longer the better.

Of course, if you are not in a hurry to move in, you can ventilate it for a while longer. In principle, the longer the ventilation time, the better the formaldehyde removal effect, especially for the winter when the indoor temperature is relatively high. Because formaldehyde also has a characteristic, the higher the temperature, the greater the air humidity, the faster it will volatilize!

The concentration of formaldehyde in indoor air is related to the following four factors: 1 indoor temperature, 2 indoor relative humidity, 3 indoor material loading degree (i.e., the surface area of formaldehyde emitting materials per cubic meter of indoor space), 4 indoor air exchange (i.e., indoor air circulation). Under the conditions of high temperature, high humidity, negative pressure and high load, the intensity of emission will be exacerbated.

The measured data show that under certain conditions, the concentration of formaldehyde in the air in the small environment of the living room can be gathered above the standard allowable level, and the release period is relatively long, and the release period of indoor formaldehyde is 3-15 years.

Therefore, for the sake of health, you should still take more precautions and preparations:

1. More ventilation, which is the most fundamental way to purify indoor air.

2. Place green plants to purify the air and beautify the environment and mood.

3. Placing activated carbon can effectively adsorb the five major pollution culprits in the air.

4. Use formaldehyde repellents and the like, such as having a pure natural "real and healthy wind". "

1.The chemical method is generally to use formaldehyde in the air to react with phenol reagents to generate azine, which is oxidized into blue-green compounds by ** iron ions in an acidic solution, and is quantified according to the color shade and colorimetry. Pick a test box and generally look at these three points:

1.It is better to add an anti-jamming agent.

2.Be sure to buy the glass bottles.

3.Mechanical filling. Qingyi test box.

2.The physical calculation method is generally a multi-purpose test tester now, but the sensor in the tester is very demanding, and now the general cheap ** is not credible, it is recommended to buy some ** relatively high testers. Hope it helps.

Ask a question, the new house is occupied, and it feels tasteful.

The smell of new furniture.

Answer yourself at home can use the formaldehyde test box for testing, this is the easiest way, the release of formaldehyde in the new house is relatively large, and the release of the life is relatively long, it is not easy to completely remove it in a short time, so how should we deal with it, recommend several long-term treatment methods of formaldehyde to everyone.

Question: Does formaldehyde work for testing?

Answer: Opening doors and windows to allow air to circulate naturally, venting harmful gases to the outside through air flow, is simple and effective. Try to keep the windows open for ventilation indoors for a long time, and you can also use electric fans to assist in accelerating indoor and outdoor air convection flow, forced ventilation for a month, and the decoration taste will be greatly reduced. It is best to place the newly purchased furniture at the ventilated outlet, so that the odor is directly excluded outside.

Ask the question to find the formaldehyde testing company.

It's winter, it's been three months since the renovation, and I moved in today.

Asking questions smells good.

3. After color development, please compare the test strip with the colorimetric card within 10-15 minutes, the color is darker than the critical value for formaldehyde exceedance, and the color is lighter than the critical value for formaldehyde is not exceeded.

It's dangerous to have a smell, and even if you don't smell at all, you can still exceed the limit, not to mention that you will smell it now.

You can directly buy a household smart formaldehyde detector on e-commerce**, such as JD, which is easy to operate and has accurate data.

I am also using it at home, so I recommend the next paragraph.

You can buy test strips online and test them yourself, or you can find a professional testing agency to test with professional instruments.

1. You can judge according to your own or your family's physical condition. If you feel unwell, dizzy, weakened immunity, or your family members are sick collectively and feel that your eyes love to cry after moving into a new house, it is normal for the indoor formaldehyde to exceed the standard.

2. You can choose a professional formaldehyde removal company to come to the door for testing, they will use the formaldehyde detector to detect, the results of the detection will be more accurate, and the formaldehyde treatment can also be carried out directly. However, it is more expensive to hire a professional company, so you can consider it if the economic conditions are better.

3. The simple way to detect whether formaldehyde exceeds the standard is to use a formaldehyde detection box, which is also simple and easy to operate. The test cassette is similar to a pH test strip, and can be used to identify whether formaldehyde exceeds the standard by color.

4. Observe the reaction of animals and plants, if you find that a large number of plants have withered and died after moving into a new house, if you have pets at home, pets are sick, do not like to eat or even die, etc., it also means that the formaldehyde at home exceeds the standard.

<>1. Please ask a professional testing institution to test indoor formaldehyde. Choose a professional testing agency to protect your legitimate rights and interests. 2. Use the formaldehyde detection box to detect indoor formaldehyde.

It can quickly detect the formaldehyde content in the room, which is easy to operate and suitable for individual testing. 3. Use sensors to detect indoor formaldehyde content. There are electrochemical sensors, optical sensors, etc., professional and systematic.

4. Detect indoor formaldehyde by electrochemical analysis. The changes of current, electricity and potential in the chemical reaction are quantitatively analyzed to determine the content of formaldehyde. 5. Chromatography is used to detect indoor formaldehyde.

The separation function can be directly used for the detection of formaldehyde.

There are many ways to detect formaldehyde exceedance, as follows:

1. Formaldehyde testing instrument: When using, it is necessary to open the house for ventilation for half an hour, and then close the doors and windows. There can not be many people indoors, and it is controlled to about 2 or 3 people.

After calibration, turn it on, and after a certain period of time, we will take a look at the data on it, if it does not match the qualified data, an alarm will sound. The advantage of this method is that it is more accurate, but it will be higher than the number of hailstorms.

2. The test strip for formaldehyde test is relatively cheap, but there is a certain error. Only according to the evaluation of color difference, a rough range can be given, and some of the range deviation is very large.

3. You can ask professional personnel to come to the door for testing, which will be charged according to the size of the indoor area, which is still more professional, and the data read out is usually more accurate.

Formaldehyde removal tips: activated carbon adsorption method, put two to three dishes per house, 72 hours can be based on potato sails to remove indoor odors. Ventilation method, through the circulation of indoor air and external air, thereby reducing the harmful substances in the indoor air and reducing the harm of such substances to the human body.

Plant deodorization method, the general indoor environment in the case of mild and moderate pollution, the pollution value is less than 3 times the national standard, the use of plant purification has better results, according to the different functions of the room, the size of the area to select and place plants. Usually, in a room of about 10 square meters, two pots of plants with a height of one meter are sufficient.

To measure whether the formaldehyde in your house exceeds the standard, you can use the formaldehyde self-test box.

The formaldehyde self-test box is a self-test product that reflects the formaldehyde content through color reaction, mainly for a rapid semi-quantitative experience of formaldehyde that may be affected by the living environment, and can determine the degree of formaldehyde and canine pollution.

Main features: easy and fast operation; Low lower limit of sensitive detection; No special instruments are required; Single-use packaging without secondary pollution; It can be operated by itself on site.

Name: Formaldehyde self-test box detection range (standard): minimum resolution: mg m3 Sampling method: turn off the detection point for 1 hour Display mode: produce color change.

Detection scope: rapid detection of formaldehyde content in the internal air of homes, offices, hotels, hospitals, schools, furniture, automobiles, etc.
