For living places, we all hope that we can have a perfect layout. As we all know, house decoration is a vast project, and the customization of ceilings, floors, furniture, and the purchase of screws are very complicated things. However, for new houses, there are often a large number of pollutants produced during the process of dressing up. In particular, harmful gases that are volatilized from some decoration materials are harmful to us, such as formaldehyde. How do you detect indoor formaldehyde ? Let's take a look with Xiao Bian below and hope to help you.
How to detect indoor formaldehyde
First, the basic method of detection
1. After getting up early in the morning, you feel bored, nauseous or dizzy. At the same time, someone at home has frequent colds. Children often cough, sneeze, and have decreased immunity. In addition, even if they do not smoke, they often feel uncomfortable. Foreign body sensation, poor breathing, etc. These symptoms all indicate that the formaldehyde in the home has exceeded the standard.
2. People in the family all suffer from a common condition. After being away from this situation, the symptoms have obviously improved and improved. Newly-married couples are not pregnant for a long time and no reason can be found. Pregnant women find fetal malformations under normal pregnancy conditions. In addition, in the new home, the plants are not easy to survive, the leaves are yellow and withered, and the furniture is pungent and odorless and does not disperse for a long time.
Second, the professional method of detecting formaldehyde
1, can issue an authoritative inspection agency CMA report
This is currently a more professional detection method, but the charges will be relatively more expensive, for some ordinary users, most of them can not afford this method, but this detection requirements are also very high, only to obtain a certificate of measurement certification Third-party testing agencies are allowed to use the CMA chapter on inspection reports, and inspection reports covered with CMA chapters can be used for product quality evaluation, results and forensic verification, and have legal effect.
2, in addition to formaldehyde company
If you want to test this way, try to find companies that use imported equipment, so that the credibility is higher, and domestic "four-in-one" "6-in-1" testing equipment, you can manually adjust the data, the result is very unreliable .
3, formaldehyde self-test box
This method is currently used in many people's homes, but Xiao Bian thinks that its accuracy is not high, due to the relatively low volume of formaldehyde self-test box gas production, and in the process of operation without temperature and humidity correction, the error is extremely large Therefore, Xiao Bian does not recommend using formaldehyde self-test cartridges for testing.
How to effectively remove indoor formaldehyde
The first thing to do is to pay attention to the ventilation of the windows so that the air flow in the room can reach a sufficient degree of patency. If this kind of method cannot completely discharge such harmful substances, it should be removed with physical methods. Of course, the method of deodorization of plants is also quite good, not only economical At the same time it is very beautiful.
Summary: The above is about how to detect indoor formaldehyde content explanation, I believe that users have a better understanding of how to detect indoor formaldehyde , of course, if you have better suggestions and ideas, please feel free to consult Xiao Bian.
Formaldehyde detection
Swing Bearing Also named Swing Circle, Slewing Ring, The slewing bearing of excavator realizes the rotation of the device by the action of friction and lubrication, which can drive the mechanical rotation and provide support capability in excavator.
A slewing bearing or slew[ing] ring is a rotational rolling-element bearing that typically supports a heavy but slow-turning or slow-oscillating load, often a horizontal platform such as a conventional crane, a swing yarder, or the wind-facing platform of a horizontal-axis windmill. (To "slew" means to turn without change of place.)
