Formaldehyde mainly comes from fibers, paints, various synthetic woods, furniture, etc. used in interior decoration. It is hidden in various places, causing headaches and insomnia, and it will lead to fetal malformation and cancer. Therefore, we are best to carry out formaldehyde testing when we stay in a new home. The following small series will introduce you to some specific testing methods.
1. Formaldehyde self-test box for formaldehyde detection method:
Formaldehyde has a destructive effect on biological cell proteins and is a highly toxic protoplasmic substance listed as one of the carcinogens in international cancer research. The formaldehyde self-test box is a self-test product that reflects the formaldehyde content through color reaction. The general test range is within 10-12 square meters. The box function is similar to a ph test paper, and a formaldehyde score can be obtained by color comparison. If the test liquid appears blue is an indication of exceeding the standard, you should consult a professional company as soon as possible. However, the indoor formaldehyde content standard is not higher than 0.08 mg / cubic meter, the self-test box error is large, the test data is not accurate, can only be used as a reference.
The self-test box is a simple and easy method, but there are also defects in the error of the test results. Under normal circumstances, the test liquid is blue, you should contact a professional testing agency for scientific professional testing as soon as possible.
2. Physical and chemical methods for formaldehyde detection methods:
The detection of formaldehyde is mostly the use of physical and chemical methods, which is the most sophisticated method, and is also used by third-party testing companies, the average person is incapable of using. The detection methods mainly include: AHMT spectrophotometry, phenol reagent spectrophotometry, gas chromatography electrochemistry, and sensor method.
3. The reaction of plants and animals with formaldehyde detection method:
Observing the response of animals and plants can also detect formaldehyde to a certain extent, such as the death of plants, which happens just after moving into a new home. Raised pets are sick, do not eat food, have low resistance, decline in vitality, and always like to stay quiet. If this happens, and your family has a similarly low resistance response, you can basically be sure that your new home is problematic.
4. Self-test method for formaldehyde detection method:
Judging according to your own feelings, for example, after the family moved into a new home, they have a common cold, low immunity, and easy to get dizzy. The energy drop is easy to get tired. I feel a pungent smell, especially when I am close to a certain piece of furniture. At this time, do more precise inspections as soon as possible, and keep the room well ventilated.
5. Third-party testing institutions for formaldehyde detection methods:
Generally, individuals cannot directly detect formaldehyde. This invisible thing can only be detected by some physical and chemical methods. We will introduce these methods below, but if you dismiss these methods or do not understand them at all, you can find them. Third-party testing companies, they will issue relevant test certificates.
