Today's dry goods knowledge is an important topic that has been repeatedly mentioned by people, repeatedly mentioned and repeatedly mentioned - formaldehyde.
Is there no formaldehyde in solid wood?
Formaldehyde: I am here!
1. There is no smell in the inner chamber, it does not mean no formaldehyde. When you smell the smell, it means that the formaldehyde has been seriously exceeded.
2. 40% formaldehyde solution is what we often call "formalin".
3. Formaldehyde is a pure natural product. It is ubiquitous in nature, including formaldehyde in trees, animals and humans.
4. It is normal for the wood itself to contain formaldehyde. Even solid wood, there is no formaldehyde at all.
5. Formaldehyde in floors or in various cabinets, mainly from glue used in wood processing.
6. In addition, not only wood, but also some fabrics may contain formaldehyde.
The toxicity of formaldehyde is particularly large, and it must be severely cracked!
Formaldehyde: What about it... (whisper bb)
7. Formaldehyde is listed as a Class 1 carcinogen along with benzene, caffeine, alcohol, and tobacco on the IARC list of carcinogens.
8. When the concentration in the indoor air reaches 0.1 mg/m?, there is odor and discomfort.
9. When the concentration in the indoor air reaches 30mg/m?, it can immediately cause death.
Completely remove formaldehyde?
Formaldehyde: I really want you to see how I look up!
10. Formaldehyde will be continuously released and can be discharged for approximately 3 to 15 years.
11. Don't blindly believe in “drying the houseâ€, the test results shall prevail.
12. We can't completely remove formaldehyde. All we can do is to control the formaldehyde content in the standard line to reduce its harm.
Vinegar smoked formaldehyde? Green plants absorb formaldehyde?
Formaldehyde: You are too funny to be a human being...
13. The higher the temperature, the faster the separation of formaldehyde from the adhesive.
14. Vinegar fumigation method, because heating increases the release of formaldehyde, and vinegar can only cover up the smell of formaldehyde, no treatment effect.
15. The method of removing formaldehyde from green plants has had little effect. Even if you give the whole room to the green radish, the effect is not necessarily ideal.
16. Green plants cannot survive for a long time in indoors with high formaldehyde concentrations.
17. The absorption of formaldehyde by basin water is not reliable. The basin has a limited area and a small absorption, and the formaldehyde will volatilize after being dissolved in water.
18. Lemon and grapefruit skin can only cover up the smell of formaldehyde without any effect of removing formaldehyde.
19. The charcoal package can only passively adsorb the formaldehyde around it. If the charcoal that adsorbs formaldehyde is not replaced in time, the absorbed formaldehyde will be released again.
20. The diatom mud wall surface has the same principle as the charcoal package. It has no purification ability and will only continuously absorb formaldehyde.
Strong ventilation, fresh air system, air purifier...
Formaldehyde: I am leaving!
21. Select materials that meet the standards and start to prevent formaldehyde from the selection of materials.
22. E1 grade wood-based panels = can be used directly indoors; E2 grade wood-based panels = must be allowed to be used indoors after finishing treatment.
23. The national standard E1 is safe enough and easy to buy. For a more budget, consider the California F4 star standard for CARB standards in California.
24. Determine whether the quality of the board meets the grade standard. Look at the CNAS accreditation certificate, which is authoritative and easy to understand.
25. When the outdoor air is good, opening the cabinet and opening the window to force ventilation and convection is the most effective method of removing formaldehyde.
26. Fresh air systems are less efficient than window ventilation and can be used as an aid in the event that windows cannot be opened.
27. There is no “puraldehyde CADR value†air purifier in the indicator, which has no purification capacity.
28. The higher the “formaldehyde CADR value†of the air purifier, the faster the purification rate.
29. The “CCM value†of an air purifier represents its “purification enduranceâ€. The higher the value, the longer the purification.
30. In addition to formaldehyde, new homes also contain pollutant gases such as benzene and TVOC. Please rely on the formaldehyde treatment company to treat them together.
to sum up
It is important to prevent home improvement materials that meet the standards. Then, please remember that vinegar can't be done, green plants can't be done, lemons, grapefruits, oranges (persimmons, plums, pears...) can't do it...
The most useful method of formaldehyde is to open the window to force ventilation and convection. If the window cannot be ventilated, use the fresh air system for ventilation. In addition, some green plants, charcoal bags, air purifiers and other auxiliary treatment.
If you are rich and anxious, please ask a special, reliable formaldehyde management company to come to your door.
