As we all know, the formaldehyde in the room after the renovation of the new house will exceed the standard. However, the harm caused by formaldehyde to the human body is very large. We can only select environmentally friendly decoration materials to reduce indoor formaldehyde. Therefore, after a new house is renovated, it will not be immediately admitted and the new house will be cooled for several months to remove indoor harmful substances. Formaldehyde is a human health killer confessed to, living in an environment with excessive levels of formaldehyde for a long time, and it can cause people to suffer from various diseases. So, what are the specific hazards of formaldehyde in new homes? How do you remove the formaldehyde in new homes?
The harm of formaldehyde:
Formaldehyde is a colorless, pungent flammable gas that is soluble in water, alcohols, and ethers. Formaldehyde is particularly harmful to the human body. If people inhale 60-120mg per cubic meter of formaldehyde, they can cause bronchitis and serious damage to the human lungs; if people stay in the 20-70mg per cubic meter of formaldehyde for a long time In the process, people will experience headaches, weakness, insomnia and loss of appetite.
If we directly inhaled 12 ~ 24mg per cubic meter of formaldehyde, there will be severe nasal, pharyngeal mucosal burns, tears, cough and other symptoms; if the direct oral 10 ~ 20ml of formaldehyde will directly lead to human poisoning death. If people are in the environment of 12mg per cubic meter of formaldehyde for a long period of time, symptoms such as drowsiness, weakness, headache, finger tremors, and vision loss will occur. The maximum allowable concentration of toxic substances in the air of workplaces and workplaces is 0.5 mg per cubic meter, including formaldehyde.
Removal of formaldehyde:
1. Ventilation method to remove formaldehyde: Through the circulation of indoor air, the content of harmful substances in indoor air can be reduced, thereby reducing the harm of such substances to human body.
2. Activated Carbon Adsorption Process Activated Carbon: Activated Carbon Adsorption Process Activated carbon is an internationally recognized drug addict. Activated carbon technology is relatively mature, without any chemical additives, has no effect on the human body, and does not cause secondary pollution through physical adsorption. Place several tens of grams per square meter, 72 hours can basically eliminate indoor odor. Medium and low pollution can be selected this method, also choose this method combined with other chemical methods.
Three. Tuzu: 300 grams of hot tea bubble tea two basins of water, into the room, and open the window ventilation, formaldehyde content within 48 hours will drop more than 90%, the basic elimination of irritating odor.
IV. Plant deodorization method in the low-level pollution can choose plant decontamination: general indoor environmental pollution in the mild and moderate pollution, pollution value in the national standard 3 times the following environment, the use of plant purification can achieve better results. According to the different functions of the room, the size of the area is selected and placed on the plant.
Editor's summary: The harm of formaldehyde in new house decoration and how to remove formaldehyde are introduced. I hope I can help you. For more information, please pay attention to this site.
In addition to formaldehyde formaldehyde
Multi-spectral grade of zinc sulfide has low absorption and scatter properties over its broad transmission range of 0.4 - 12μm. Zinc Sulfide Multispectral is a chemically vapor deposited material which is commonly used in thermal imaging. With its excellent transmission properties in the visible and infrared, Zinc Sulfide Multispectral is the material of choice for systems that have both visible and mid-wave or long-wave infrared sensors. It is slightly harder and more chemically resistant than zinc selenide.
We consistently offer various high quality optical components according to the customer's requirements use other infrared materials. Such as prisms,Spherical Lens, aspherial lens,Ball lens,Optical Windows,Achromatic Lens,cylinder lens etc.
