Which company is the new house to detect indoor formaldehyde?

Now there are many ways to remove formaldehyde on the market, and the best way is actually to open windows for ventilation, but the release time of formaldehyde is 3-15 years, which takes a long time, and formaldehyde can be removed in the following ways.

1. Activated carbon adsorption. Activated carbon to remove formaldehyde is a relatively simple, cheap and practical method, physical adsorption, not easy to cause secondary pollution, no chemical additives, no impact on the human body. If you want to recycle, you must take it to a sunny and ventilated place outdoors for a day before taking it back.

It's useless to just leave the charcoal bag there.

2. Photocatalyst decomposition. Photocatalyst is a catalyst that can decompose harmful organic compounds such as formaldehyde, toluene, and TVOC into harmless gases under the action of light, so as to achieve the purpose of removing formaldehyde. You can appropriately use some photocatalyst wood essential oil, leather formaldehyde removal care solution and other products, remember that the photocatalyst needs to react under the condition of light, and the more light the better.

3. Chemical purification method. The chemical purification method is a method that uses chemical reagents to neutralize formaldehyde or seal formaldehyde through chemical agents to prevent formaldehyde from volatilizing. Generally speaking, it is difficult to implement the method of neutralization by chemical reagents, and it is easy to produce secondary pollution; The way to prevent the volatilization of formaldehyde is to treat the symptoms rather than the root cause.

Users who urgently need to remove formaldehyde should be operated and used by professionals.

4. Formaldehyde air purifier. The air purifier method is a method of using an air purifier to remove harmful substances such as formaldehyde in the air. This method of removing formaldehyde is somewhat similar to the activated carbon adsorption method, because the general air purifier is adsorbed and filtered by the activated carbon filter to adsorb and filter toxic substances such as formaldehyde.

For example, the Langkong aldehyde energy king air purifier is very worth buying.

This can also be tested by yourself, depending on the actual situation of the decoration, if it is simple, you can test it with a formaldehyde detection box, and you need to report something to be tested by the institution.

1. Shenzhen deep testing and testing technology. Founded in 2015, the company is an independent and professional third-party environmental testing organization. We are committed to providing customers with scientific, accurate, efficient and fair inspection and testing services.

In accordance with the standards, the deep measurement environmental testing has obtained the CMA measurement certification qualification.

2. Tianjin Lipeng Sanitizing CompanyTianjin Lipeng Sanitizing Company. It is a subsidiary of Tianjin Lipeng Technology, and a company specializing in formaldehyde removal and formaldehyde testing in Tanggu area, Tianjin, with rich experience.

3. SGS formaldehyde testing company. With professional equipment and high-quality personnel, the products are reliable and the test results are very accurate.

There are 2 types of testing institutions on the market:

1. There is a testing agency for formaldehyde removal business, which is generally cheap, and there will be moisture in the later data, the purpose is to promote the formaldehyde removal business later.

2. Qualified testing institutions will be more expensive, but the test results will definitely be no problem, and there will be no other business to be promoted later.

It is best to find a qualified testing company to do formaldehyde testing, so as to improve the testing efficiency and service quality and ensure the accuracy of the test results.

Decoration air testing process: In strict accordance with GB T18883-2002 and GB50325-2010 standards, the testing personnel will come to collect air samples, laboratory testing and analysis, senior engineers will review and sign, and issue test reports; The cycle is about 3-4 working days.

1. The importance of laboratory testing for formaldehyde and other pollutants: Formaldehyde testing in new houses is related to the life and health of you and your family, and you must experience a rigorous and complex experimental process in order to get scientific test results; The instrument that can measure formaldehyde on the spot is not scientific, the instrument cannot pass the CMA measurement certification, and its cost and reagents are relatively low, so it is mostly free or low-cost testing, and formaldehyde is detected for treatment; It cannot support the protection of life and health.

2. What to do if the formaldehyde detection exceeds the standard: our center will tailor it according to your detection value and decoration situation; While doing a good job of component analysis, trace back to the source of pollution, and give you a scientific solution and recommended use time.

3. What kind of suggestions will the industry authorities give about the removal of formaldehyde: the traditional formaldehyde treatment process is mostly high-temperature fumigation, spraying aldehyde remover, spraying photocatalyst, releasing ozone, etc.; Such processes can produce secondary pollutants as well as corrosive furniture. Formaldehyde is generally used as an adhesive, mostly existing in the inside of the board, so it cannot be used; Moreover, indoor pollutants are not only formaldehyde.

1.Professional testing institutions: Now there are many testing institutions and companies, as for which one is more professional and formal, the online statements are different, this still needs friends to choose carefully, here we recommend gold standard testing, is a testing and evaluation agency approved by the state, with CMA qualifications.

2.Formaldehyde detection box: easy and fast operation;Low lower limit of sensitive detection;It can be operated on site and other characteristics, so many people choose to use this, but although it is convenient, the detection effect is not ideal, and the error is very large.

3.Formaldehyde detection method sensor - the sensor used to detect formaldehyde includes electrochemical sensor, optical sensor and photobiochemical sensor.

Summary: After the interior decoration test, if you still feel that the newly renovated house is uncomfortable, or the air quality is not good, you can ventilate it frequently, and use it with lotting stone or activated carbon to remove formaldehyde.

Indoor environmental testing must find a third-party authority to be credible, and there must be an independent laboratory for analysis. In addition, the testing standard should be considered, the 50325 standard can only be used for the acceptance of decoration projects, the requirements are relatively low, and it is not suitable for the indoor environment after the furniture enters the siteThe 18883 standard belongs to the environmental category, and the requirements are more stringent, requiring constant current atmospheric sampler and secondary thermal analyzer, Nanjing has 18883 qualification, and Nanjing Yicheng environmental testing and CMA qualification certification meet the 18883 standard.

There is a mixture of these institutions in the country, and one of them is SGS

It is very important to choose a reliable formaldehyde testing company, mainly pay attention to the following points:

1.Whether the qualifications are complete:

Before choosing a governance body, you should do some research about the institution to see if it is a regular company, whether it has complete qualifications, and whether it has a business license.

2.Detection Steps:

The formal treatment company will do a comprehensive and detailed test of indoor pollution before and after treatment, taking Shenyang Jiajing Technology as an example, the testing equipment used is synchronized with the testing equipment of the Municipal Quality Supervision Bureau, and the test results have legal effect, and special instruments will be used to obtain indoor pollution values in accordance with strict testing procedures.

3. Service quality and professionalism

In some companies, the staff is recruited casually and has not been trained before taking up the post, which lacks professionalism and is highly mobile. In fact, pollution control requires strong professional skills, which still requires professionals from formal companies.

Qualified laboratories can do formaldehyde testing if they have been approved by the department and issued a qualification certificate after review.

Yes, if you want to know whether formaldehyde exceeds the standard, this is not difficult, there are formaldehyde detectors, as well as professional formaldehyde testing companies, you can choose, once you find that formaldehyde exceeds the standard, you should immediately do a good job of removing aldehyde, the following is recommended for you several widely acclaimed aldehyde removal methods, you can choose the best, I hope to help you.

1. Formaldehyde in the new house exceeds the standard, the smell is serious, the first thing to do is to open the window for ventilation, open the wardrobe and drawers at the same time, so that the formaldehyde can be fully released, and then release the formaldehyde to the outdoors through air convection, although this step is simple to operate, but also pay attention to the weather conditions, this method is not suitable for the rainy season and winter.

2. Activated carbon is a more effective method to purify the air, it has a strong adsorption effect on formaldehyde and other harmful substances, and the smaller the particles, the better the adsorption effect. It should be noted that most activated carbons have certain adsorption limits, and once saturated, they will no longer be absorbed, but will appear desorption, releasing absorbed harmful substances.

5. The blades of the fan can cut the air to promote the airflow in the process of rotating, so as to realize the replacement of indoor and outdoor air, accelerate the discharge of formaldehyde-containing air, and effectively reduce the concentration of indoor pollutants, but it can only treat the symptoms but not the root cause, and this method may not be practical in the warm season.

Now there are some departments on the Internet that detect formaldehyde, but in fact, this kind of thing is useless. Formaldehyde removal is only a matter of time, because formaldehyde and other toxic gases are released for more than 10 years, how can it be removed at one time. The best way is to ventilate the room more, and it is good to raise some green plants that adsorb harmful gases in oil.

1. The large-scale units of the Quality Supervision Bureau and the Environmental Protection Bureau have accurate measurement and high cost.

2. Personal air treatment company, on-site testing, and data from time to time.

3. Household formaldehyde monitor, 24h monitoring, automatic alarm when exceeding the standard.

4. Most of them are charged according to the number and size of the room.

5. In addition to the above parts, you can also use the formaldehyde detection box, which has the characteristics of convenient and fast operation, low lower limit of sensitive detection, and on-site self-operation, so many people choose to use this, but although it is convenient, the detection effect is not ideal, and the error is very large.

Each region has a special agency for testing formaldehyde in houses, which can be found on the official website of the local market supervision and administration bureau. Testing institutions with CMA qualification can do formaldehyde testing for houses. Generally, the distribution detection is carried out by room.

**Differences exist on the subject. Generally, it is around a few hundred yuan to thousands of yuan. The test items are based on the standard of GB-50325-2020 or the standard of GB T18883-2002.

It depends on the choice of the owner.

Summary. At present, there are generally three types of institutions that can carry out formaldehyde testing: the most authoritative of which is the Environmental Protection Bureau, the Center for Disease Control and Prevention or the Bureau of Quality and Technical Supervision, which are the most important institutions, and the laboratory hardware and technical personnel are relatively strong and standardized, but this kind of formaldehyde detection institutions generally do not provide formaldehyde testing services privately.

Another kind of third-party CMA formaldehyde testing company in the society, this formaldehyde testing department specializes in providing commercial testing services to the society, and this kind of organization has been certified by the provincial or national metrology agency as a qualified professional testing institution.

It can provide testing services for water quality, atmosphere or other performance to ordinary families or enterprises, and its testing capabilities and test reports issued are fair and legally effective, and can be used for disputes and lawsuits to protect rights. At present, most cities in our country have similar third-party CMA formaldehyde testing institutions.
