"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 in decoration comes from the accumulation of various materials and products, blockboard, MDF and particleboard and other man-made boards, coatings, wall coverings, wallpaper and other wall materials, as well as home fabrics are the source of formaldehyde.
Qualified environmental protection building materials do not mean that there is no pollution at all, the formaldehyde content of a single product is up to standard, and a variety of household materials are used in the same space, which will still cause the possibility of excessive pollution.
Do you know about the two characteristics of formaldehyde?
Formaldehyde is one of the most common pollutants in interior decoration. Many times, when people talk about formaldehyde, they can't help but talk about "aldehyde" discoloration? So, why is formaldehyde so terrible?
First, it has a wide range of existence
The problem of decoration pollution has appeared as early as 20 years ago, although in recent years the public's awareness of prevention and control has been increasing, but because the material pollution still exists, the problem can not be fundamentally solved. "The most common source of formaldehyde pollution in households is urea-formaldehyde glue contained in boards, especially wood-based panels. ”
Second, the evaporation time is long
As we all know, the volatilization time of formaldehyde will be very long, especially the formaldehyde contained in decoration materials such as wood-based panels, and the release time can be as long as 3-15 years.
Why does formaldehyde not disappear in the short term, but continues to volatilize? In order to pursue a better degree of adhesion, today's decoration materials usually mix formaldehyde and urea at high temperatures.
In the subsequent use process, the free formaldehyde in the material will be released continuously and slowly.
Formaldehyde "big households" have exploded: these four daily necessities are less moved home!
1. Synthetic plates and glues
Formaldehyde in new house decoration materials mainly exists in boards, generally wardrobes, shoe cabinets, lockers, ecological boards used in tatami mats, paint-free boards, plywood, blockboards, MDF and particleboard contain higher concentrations of formaldehyde.
At present, the adhesive used in the production of wood-based panels is urea-formaldehyde resin with formaldehyde as the main component. All the plates that can be glued have formaldehyde.
In addition, there are some latex adhesives used for wall treatment, which are enclosed in the wall, and the formaldehyde in this part of the latex is difficult to remove and the evaporation time is longer.
2. Brightly colored textiles
The prerequisite for the presence of formaldehyde in textiles here is that its color is very bright and bright.
For example, like some red or purple curtain covers, etc. These will contain some formaldehyde, as well as some brightly colored textiles that are often seen in the market. There are a lot of formaldehyde components in it, and the brighter the color, the more formaldehyde it has.
3. "Unqualified" mattresses
Latex mattresses are loved by a wide range of consumers because of their comfort and lightness. But no matter how good things are, they will always be accidentally destroyed by the black hands of unscrupulous merchants.
In the production of some latex mattresses, unscrupulous merchants will replace them with defective materials in order to save costs, and these defective materials are likely to contain some fabrics, sponges and so on that contain excessive formaldehyde.
If people sleep on such a mattress for a long time, they will often feel dizzy.
4. Wallpaper with complex patterns
Many people have the idea of sticking wallpaper when decorating the house, and it is true that sticking some attractive wallpaper can enhance the overall home decoration style, but the same wallpaper also contains formaldehyde.
Because the construction of wallpaper requires the use of glue, and these glues usually contain a lot of formaldehyde content, so we can use latex paint and other items when decorating the wall, or a lot of ventilation to the wallpaper, so as not to cause formaldehyde pollution.
It is said that formaldehyde is harmful to human health and safety, and what aspects will the impact be reflected in?
Excessive formaldehyde will affect the human respiratory system, nervous system, skin and other parts, and the most important thing is that formaldehyde can cause cancer.
1. Inhalation of formaldehyde will directly affect the human respiratory system
Formaldehyde is relatively soluble in water, because the upper respiratory tract of the human body is relatively moist, most of the formaldehyde inhaled into the human body is absorbed in the upper respiratory tract, and a small part will enter the human lungs, causing lung discomfort.
As a result, symptoms of upper respiratory tract infections appear: such as sneezing, coughing, etc. This is also the first manifestation of formaldehyde inhalation in the human body, and the most direct manifestation of long-term exposure to formaldehyde residue in the room is to cause rhinitis and asthma.
2. Formaldehyde can cause degeneration and necrosis of the nervous system
According to studies, formaldehyde can cause degeneration and necrosis of the nervous system, and people who are exposed to formaldehyde for a long time (such as anatomists) may have different degrees of headache, memory loss, reduced sensitivity, reduced coordination function, sleep disorders and other symptoms.
This is also the reason why the hospital dissection room focuses on the treatment of formaldehyde, and the hospital dissection room seals the pathological test samples with "formalin", which is a diluted solution of formaldehyde, and the formaldehyde in the dissection room exceeds the standard by nearly 1,000 times under normal circumstances.
3. It can cause skin lesions and allergic symptoms
According to research, direct skin contact with formaldehyde will cause skin itching, slight rash and other allergic symptoms, especially for patients with dermatitis or eczema, and it is easy to aggravate the condition in an environment where formaldehyde concentrations exceed the standard.
If you have moved to a new house or changed rental housing, and the above three problems occur for no reason, please do not be careless. It may not be a cold, it is very likely that the formaldehyde in the room exceeds the standard.
For the health of ourselves and our families, we must not ignore formaldehyde, if we want to remove formaldehyde safely and efficiently, in addition to daily ventilation, it is best to match a professional player!
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.
