"Formaldehyde" is related to the safety of people's lives, and "excessive formaldehyde" has always been one of the hot issues that the general public is concerned about, and most of them will also link formaldehyde with "leukemia".
Leukemia, also known as blood cancer, is a physical disease that seriously threatens human life and health.
When it comes to leukemia, everyone may unconsciously think of children, and yes, children are the group with a high incidence of leukemia.
The reason for this is that the physical function of children and adolescents is not fully developed, and some children are easily troubled by leukemia because of their low immunity and immunity.
Formaldehyde is a colorless gas with a pungent odor, formaldehyde is relatively soluble in water and ethanol, 40% of the aqueous solution does not become formalin, formaldehyde also has the ability to reduce,
It can form an explosive mixture in vapor and air, so it is very dangerous. In 2017, formaldehyde was included in the list of carcinogens by the World Health Organization's International Cancer Research Institute.
When the indoor formaldehyde concentration exceeds 0.1, it is an excess of the standard, which is abnormal. Formaldehyde is recognized by the World Health Organization as a class of carcinogens, when indoor formaldehyde is seriously exceeded, it will increase the risk of cancer in the human body, so when the new home is renovated, do not rush to move in.
Formaldehyde has become one of the mandatory indicators in the health standards of public places in mainland China.
Formaldehyde is highly volatile at room temperature at minus 19 °C, soluble in water, and the volatilization rate accelerates as the temperature rises.
The background value of formaldehyde in nature is very low, and the annual average concentration of formaldehyde in urban air is 0.005-0. 01 mg/ m3 。
"Formaldehyde big households" have been exposed: don't buy these 4 daily necessities, all of them are "formaldehyde sources"
1. Oil-based latex paint
Oil-based latex paint contains a large amount of formaldehyde, and if oil-based paint is used during decoration, formaldehyde will be difficult to volatilize in the new home.
Therefore, do not use oil-based paint to paint the wall, try to use water-based topcoat and primer.
2. Complex wallpapers
We all know that when decorating, many of us will not choose simple paint, but will choose a variety of patterns, very complex wallpaper, wallpaper patterns are more, and it looks magnificent, in line with many people's aesthetics.
But complex wallpaper, in the process of making there are also some plants and trees, glued together, these glues also contain formaldehyde, wallpaper also needs to be watered to smear, pasted on the wall, in order to gradually firm and smeared These glues also contain a lot of formaldehyde, so you must be cautious when choosing wallpaper and watering.
3. Colorful curtains
When making curtains, in order to make it colorful and look good, a large number of dyes will be added during the printing and dyeing process, and these dyes usually contain formaldehyde, therefore, the curtains of the finished product are prone to formaldehyde residues.
It is recommended that the newly bought curtains should be soaked in water and cleaned to dissolve and release formaldehyde, which can greatly reduce the risk of formaldehyde.
In addition, when buying curtains, try to avoid colorful styles, and it is best to choose cotton, linen, silk and other pure natural materials, which are safe and hygienic.
4. Auxiliary materials such as sewing agents
Sometimes people are easy to fall into the misunderstanding, thinking that only some large materials will produce formaldehyde, in fact, some small or auxiliary decoration materials or accessories also contain a large number of harmful gases, such as auxiliary materials such as sewing agents.
In fact, those who have used the beauty sewing agent know that he has a pungent smell, because it also has harmful substances such as V o C and formaldehyde, which is no less dangerous / harmful to the body/health/than latex paint, so be careful when using, if you do not pay attention, it will also constitute a threat / threat / threat to our / health / health.
Furniture using environmentally friendly materials, is formaldehyde not exceeded?
When decorating, in order to save the economic cost and time cost of removing aldehyde, many owners will deliberately buy furniture that uses environmentally friendly materials, and can move into a new house in the shortest possible time.
But this has also allowed many businesses to pick up business opportunities and introduce eco-friendly furniture to the market. The principle is to reduce the formaldehyde concentration from the source and minimize the pollution.
So the question is: does the formaldehyde really not exceed the standard for furniture using environmentally friendly materials?
In response to this problem, the results of the network survey are: 36% of people think that the selection of environmentally friendly decoration materials formaldehyde will not exceed the standard, and 64% of people think that the choice of environmentally friendly decoration materials does not mean that formaldehyde does not exceed the standard!
How to judge the indoor formaldehyde in which you live exceeds the standard? These 3 signs on the child's body are obvious, and you must move out
1. The child has headache, diarrhea and throat inflammation
If the child has a headache, diarrhea and throat inflammation, many parents will use ordinary methods to treat the fever to see the child, but if the child has a fever that does not go away, then the parents are in a hurry and will send the child to the hospital for examination.
Therefore, parents should pay attention to the fact that one of the symptoms of leukemia is fever, and it is a repeated high fever.
2. Children always cry out in pain inexplicably
If the child cries out of pain for no reason, but there is no injury in the body, don't be careless, it may hurt in the bones.
joints and other places. Pain in the bones and joints and bones is a common symptom of leukemia in children, so it is important to see a doctor.
3. The child has nosebleeds and bleeding gums
If the child has nosebleeds or bleeding gums when brushing his teeth, and there are blood spots on his body, and sometimes vomiting, this is also one of the precursors of leukemia, and parents should pay attention.
In the above situations, whether it is formaldehyde poisoning or not, it should be dealt with in time, and do not be careless!
Formaldehyde removal is not a project that can be completed in a short period of time, the formaldehyde emission time is generally 3-6 months, it is necessary for us to continue to remove formaldehyde, the following Xiaobian will share with you a few effective formaldehyde removal products, the first of which is Xiaobian himself used one, the effect is very good.
1: Olvway formaldehyde scavenger:
Allova formaldehyde scavenger adopts a new "amino acid + photocatalyst" formaldehyde removal technology, which combines the characteristics of physical removal and chemical decomposition, and provides an innovative solution for the rapid and efficient degradation of formaldehyde molecules. The core is the fusion of amino acid technology and photocatalyst technology, which reacts with air to produce carbon dioxide and water, and does not produce harmful components to the human body. Through adsorption and chelation, amino acid technology effectively adsorbs and fixes harmful gas atoms and molecules such as formaldehyde on the surface of the material, improves the degradation and removal efficiency, avoids its re-release into the indoor air, and ensures the improvement of indoor air quality.
Olvway Formaldehyde Scavenger: The ingredients are safe and reliable, free of oxidants, alcohol and fragrance, and very safe for home use. Tested by professional testing institutions, the efficiency of this product to remove formaldehyde is as high as 91%, which is a favorable player for removing formaldehyde.
2: Activated carbon:
Activated carbon itself has a certain effect on the adsorption of harmful substances and volatile harmful gases, so it can be used to effectively adsorb formaldehyde, especially in the newly renovated indoor environment or in the case of excessive formaldehyde, it is an effective choice.
Three: Yiya formaldehyde deep scavenger: The composition of this formaldehyde scavenger is mild, which effectively improves the free state and the formaldehyde inside the plate, and the decomposition products are pollution-free.
