Many people will be afraid of formaldehyde in newly renovated houses, but formaldehyde is colorless and odorless, and it is generally difficult to judge whether the house has formaldehyde, so how can we accurately judge that the house has formaldehyde?
The following are the more common ways to determine whether there is formaldehyde in the room.
1.Use professional formaldehyde detection instruments to detect, professional instruments will produce a certain chemical reaction to formaldehyde, so you can intuitively judge whether there is formaldehyde in the air.
2.When there is no professional instrument, you can use the formaldehyde detection box for detection, which is a convenient and rapid one-time formaldehyde detection product for detecting formaldehyde content in the living space.
3.Smell the smell, formaldehyde is colorless and irritating gas, if you smell a pungent smell in the room, the formaldehyde content is relatively high.
4.Observation reflects that the reactions of animals and plants can be observed, such as plant wilting and dying, pets are prone to illness, low resistance, do not eat food, decreased vitality, etc., and can basically determine that there is formaldehyde in the room.
5.Observe the indoor air quality, if the indoor air quality is poor, and there are symptoms such as cough, sore throat, headache, and stinging eyes, it may indicate that there are harmful substances such as formaldehyde in the room.
Of course, in order to more accurately understand the formaldehyde content value in the house, you have to ask a professional testing agency or company to use professional instruments for more accurate detection, and the above methods can only determine whether there is formaldehyde.
In order to understand the specific detection, we must pay attention to the following matters, so as to understand the formaldehyde content in our own room more accurately and reasonably, so as to formulate a reasonable formaldehyde removal method.
1. Choose the appropriate detection method: At present, the main methods of formaldehyde detection are gas detection instruments, formaldehyde detection boxes, etc
professional testing institutions, etc. Choosing the right assay can improve the accuracy of the assay.
2.Timing of detection: Formaldehyde emissions are higher at night and early in the morning, so these two time periods can be considered when choosing the timing of testing. In addition, formaldehyde levels may also be higher during the hot and humid summer season.
3.Detection environment: When conducting formaldehyde detection, it is necessary to ensure that the detection environment meets the requirements. For example, the test should be performed 12 hours after the doors and windows are closed to ensure air circulation in the room.
4.Testing standards: The formaldehyde testing standards implemented in China include "Indoor Air Quality" GBT18883-2002, "Code for Indoor Environmental Pollution Control of Civil Construction Projects" GB50325-2001, etc. Choosing the right test standard can improve the accuracy of the test.
5.Selection of testing instruments: When carrying out formaldehyde detection, it is necessary to pay attention to the selection of formal testing instruments and operate in accordance with the instructions of the instrument.
6.Processing of test results According to the test results, if the formaldehyde content exceeds the standard limit, it is recommended to take timely measures to treat it to ensure indoor air quality.
7.Detection frequencyAfter decoration or furniture enters the site, it is recommended to conduct regular formaldehyde testing to ensure that the indoor environment meets the requirements.
For indoor formaldehyde in the home, we should first roughly judge whether it contains formaldehyde through the above methods, and more accurate detection can be carried out after judging that there is formaldehyde, and accurate detection can be used as the basis for indoor treatment of formaldehyde.
