Decoration pollution has always attracted people's attention, many people only know that formaldehyde is very harmful, but many people do not know that the release period of formaldehyde can be up to 15 years.
Formaldehyde is the main pollution in the decoration of new houses, and is recognized by the World Health Organization as a class of carcinogens, and it is generally a high volatile period within 3 years.
The toxicity of formaldehyde is not immediately reactive when inhaled, and it will be fatal unless a large amount of formaldehyde is inhaled. The decoration formaldehyde in life generally changes our respiratory system and blood system slowly over time. In particular, people with weakened immunity, such as the elderly, children, and pregnant women, are most vulnerable to harm.
1. Several abnormal manifestations of excessive formaldehyde at home
Abnormality 1: Skin allergies
Formaldehyde is highly sensitized, and if the formaldehyde at home exceeds the standard, it is likely to cause skin allergies. If you can't find the allergen, you can test whether the formaldehyde at home exceeds the standard.
Anomaly 2: Frequent coughing
If after moving into a new house, the child often sneezes, coughs, and has poor immunity, it may be because of excessive formaldehyde.
Abnormality 3: Throat discomfort
If no one smokes at home, the family will still have throat discomfort and poor breathing, which is likely to be a manifestation of excessive formaldehyde.
Abnormality 4: Prone to colds
Formaldehyde can reduce people's resistance, which can affect physical health. If you live in an environment with excessive formaldehyde for a long time, it is easy to catch a cold.
Second, latex paint is a "big formaldehyde"?
The answer is no.
Paints are divided into water-based paints and oil-based paints, and if they are oil-based paints, they contain a lot of harmful substances: formaldehyde, VOCs, heavy metals (mercury, chromium, lead, etc.), class A compounds, and so on.
Although latex paint is also a kind of paint, most of the latex paint is water-soluble, that is, water-based paint, and the formaldehyde content is not large. As long as you choose a regular brand of latex paint, you basically don't have to worry about formaldehyde.
The real "formaldehyde big household" has been found out, these 5 materials are the real "invisible assassins", don't move to your home when decorating.
1. Inferior construction accessories
In the process of decoration construction, some construction accessories need to be used. If the quality of these excipients is too poor, it is likely to contain excessive formaldehyde. For example: beauty sewing agent, putty powder and so on.
When we use the sewing agent, we can smell a pungent smell. That shows that it not only contains formaldehyde, but even some harmful volatiles. Generally speaking, the pungent smell will cause harm to the human body.
The inferior putty powder, which uses a lot of glue, will naturally have a high formaldehyde content. Moreover, putty powder is smeared on the wall, and the formaldehyde released will naturally not be less.
Therefore, when we choose accessories such as sewing agents and putty powders, we should try to choose big brands and don't be cheap. Especially putty powder, be sure to see if there is a "Ten Ring Certification" logo!
2. Unqualified mattresses
For the same mattress, some cost hundreds of yuan, while others cost thousands, with a price difference of more than ten or twenty times. Many expensive mattresses, in addition to the brand premium, there are some details of the design, that is, the materials used are assured.
There are some people who prefer to sleep on a hard bed, so they choose a palm mattress. Some cheap palm mattresses use a lot of glue to bond, and there is a lot of formaldehyde.
Generally speaking, the harder the palm mattress, the more glue is used and the higher the formaldehyde content. If you can't tell, you can pick up the ingredients. If there is delamination, it means that it is a compression process, and there is no large amount of glue. If it can't be picked up and there is no delamination, it means that it is glue bonded and has a high formaldehyde content.
In addition, there are some black-hearted manufacturers, in order to make the mattress look full and elastic, and in order to reduce costs. The sponge or padded fabric will be chemically treated, and even if it is separated by several layers of quilts, it will still seep out. It makes people feel dizzy and have poor sleep quality.
3. Brightly colored curtains
Curtains are soft decoration materials that must be used in decoration, which can not only shade the light, protect privacy, but also play a good decorative role. Many people think that the curtain is just a piece of cloth, where will it be related to formaldehyde.
This idea is wrong, the formaldehyde content of inferior curtains will not be less than other decoration materials.
Some black-hearted curtain manufacturers, in order to maximize profits, will use some chemical dyes to dye curtains. Especially those brightly colored curtains contain a lot of formaldehyde. Curtains hanging at home will naturally release formaldehyde all the time.
If you have curtains that are too brightly colored at home, it is best to soak them in water after buying them. Because formaldehyde can be dissolved in water, brushing it several times can effectively reduce the formaldehyde content.
And, when buying curtains, try to choose cotton, linen and other materials, and the color is mainly plain.
4. Man-made panels
Wooden floors, wooden furniture, storage cabinets, etc., all need to be made of boards. In order to save money, some people will choose man-made panels with excessive formaldehyde content.
Man-made panels are one of the main sources of formaldehyde pollution at home.
Because in the production process of man-made panels, a large amount of adhesive is required. Because the raw materials contain a large amount of formaldehyde, this leads to the continuous release of formaldehyde in the production and application of man-made panels.
When we use such man-made panels to lay floors, create furniture and storage cabinets, formaldehyde will always be free in the home.
Even if the man-made panels are tested, the release rate of harmful substances meets the standard. However, too much furniture and building materials at home, too little space, increased furniture density, etc., will make the concentration of formaldehyde exceed the standard.
Therefore, if there are conditions, the floor will choose solid wood flooring, and if the conditions are not enough, use tiles to pave the floor. Choose a good type of furniture and cabinet panels, and you can't save money on it.
5. Plastic furniture
Many people like to add plastic furniture to their homes, plastic furniture is not only durable, but also cheap, and the key is that it can be stacked and stored without taking up too much space.
However, the raw materials of plastic furniture are likely to contain formaldehyde, which will be slowly released when placed at home. Especially when the indoor heating is turned on, the temperature rises, which will accelerate the release of formaldehyde.
In this way, the formaldehyde content in the home will exceed the standard, and living in this environment for a long time is easy to have a negative impact on the body.
Summary at the end of the article
If you have the above 5 materials or items with high formaldehyde content at home, it is best to test the formaldehyde content at home. If the formaldehyde exceeds the standard, dispose of it as soon as possible, physical health is the most important thing, don't joke with life.
