| Is the formaldehyde self-test box really useful? | |
| 2021-05-31 | |
| Formaldehyde, something that everyone can't be familiar with, has long become the enemy of the whole people in today's society. Although many friends will take various methods to remove formaldehyde before moving in to the new house, they will eventually test the indoor formaldehyde. Only when you have a bottom line can you rest assured. However, many people do not know how to professionally detect formaldehyde. Especially many unscrupulous businesses on the Internet sell their so-called professional testing equipment for profit. Today, the editor will focus on the commonly used test boxes to see if they are accurate. The principle of the formaldehyde self-test box is a test product to find the formaldehyde content through the color card. The test result can only be used as a simple reference, and it can even be said that the reference value is very low. Because the test results are easily affected by factors such as air flow rate, indoor temperature and humidity, such as the content of indoor particulate matter, the smell of life, etc., the test results will have large errors. This is the reason why many consumers who use this product will ask why I have been living in a house for more than 5 years and it is detected that it has exceeded the standard. Having said so much, how should indoor formaldehyde be professionally tested? If conditions permit, a formal and professional formaldehyde testing agency can be entrusted to conduct indoor formaldehyde and other pollutants testing. For decorated families who are going to move in or have already moved in, according to the "Indoor Air Quality Standard" GB/T18883-2002, the room needs to be closed in advance The indoor air is sampled and tested by spectrophotometer or meteorological chromatography for 12 hours with doors and windows. The indoor formaldehyde concentration is not higher than 0.1mg/m3. This standard refers to the World Health Organization's limit standard for indoor formaldehyde concentration, which is a human living environment. The minimum standard of health. It is hoped that for the small partners who are decorating new houses, they will not be deceived by those simple testing equipment. Professional testing should still be entrusted to professional organizations. |
