Xuchang Imperial Chestnut Emperor is mainly chestnut (scientific name: chestnut BL. ), also known as chestnut, chestnut and anemone chestnut. It is a chestnut plant of Fagaceae, which originated in China and distributed in Viet Nam, Taiwan Province Province and Chinese mainland. It grows at an altitude of 370-2,800 meters, mostly in mountainous areas, and is widely cultivated. Chestnuts are rich in nutrition, and the content of vitamin C is higher than that of tomatoes and more than ten times that of apples. The minerals in chestnuts are also comprehensive, containing potassium, zinc and iron. Although the content is not as high as hazelnut, it is still much higher than that of ordinary fruits such as apples, especially the potassium content is three times higher than that of apples.

Where does the formaldehyde content in home decoration mainly come from? You have just finished decorating your new house, and you will certainly hear people say that it contains a lot of toxic substances-formaldehyde, benzene and so on. And it is best not to live in it right away. As we all know, formaldehyde is a protoplasm poison, which can combine with protein to produce formaldehyde poisons with different concentrations, and it will do harm to human body to varying degrees. The newly renovated new house just contains a lot of high-concentration formaldehyde, which can give off a smell of * * *, mainly from the paint used in the decoration process. At this time, we should pay more attention to the removal of formaldehyde in new houses. What about in addition to formaldehyde after the renovation of the new house? For this reason, Tianjin Capital Decoration has collected and consulted a lot of materials, and found some methods of new house in addition to formaldehyde to share with you.
Let's take a look at the pollution level value and detection method of formaldehyde:
Judging from the senses.
light pollution
Formaldehyde concentration value: less than 0.26mg/m3, feeling: it smells * * *.
Moderate pollution
Formaldehyde concentration: 0.26~0.5 mg/ m3, feeling: eyes, throat and nasal cavity feel slightly dry.
Serious pollution
Formaldehyde concentration value: above 0.5 mg/ m3, feeling: conjunctiva feels dry.
The national detection standard of formaldehyde is 0.08MG/m3/m2. You can use the following methods to remove formaldehyde according to the approximate degree of your feelings. Another thing is to buy a formaldehyde test box and test it yourself. The detection standard is one at each point, or one in a room, to detect the concentration of formaldehyde. Professional testing company is also a little testing (one room = one point). Generally, the charge for a point ranges from 50- 100, mainly depending on the price of testing reagents.
How to use in addition to formaldehyde's tools/materials after the renovation of the new house?
Activated carbon, grapefruit peel, etc.
How to in addition to formaldehyde after the renovation of new houses?
1, put salt water in the new house.
Based on the solubility of formaldehyde in water, we can put a few pots of salt water in each room, which can initially absorb a lot of pungent smell in the room.
2. Indoor ventilation
As we all know, formaldehyde is a volatile substance. We can use this to open the doors and windows of the room and keep the air convection inside and outside the house. This effect will last for about 2 months. However, this method should pay attention to closing the doors and windows at night to avoid being stolen.
3. Increase the indoor temperature.
Generally, formaldehyde volatilizes very slowly. If you want it to evaporate as soon as possible, you must find ways to increase the indoor temperature. You can turn on the air conditioner at an appropriate time to increase the indoor temperature and speed up the volatilization of formaldehyde.
4. Adsorption of activated carbon, etc
We can use some things with strong odor adsorption function to improve indoor air quality. At present, activated carbon is the most popular in the market. Putting about 50g of activated carbon per square meter can play a good adsorption role on formaldehyde, but at the same time, we should pay attention to the replacement of activated carbon, usually once every 7-8 months. Here, I also listed other things with this formaldehyde adsorption function. You can choose according to your needs: tea, salt water, grapefruit peel, onion slices, pineapple pieces, white vinegar aromatherapy and so on. Coal ash can also remove formaldehyde gas, so you can choose to use it yourself.
5. Green plants
Plant adsorption method is also a good choice. A large number of investigations and studies by scientists show that many green plants, such as chlorophytum, cactus, Brahma, cycad, chrysanthemum, etc., have strong absorption capacity for formaldehyde. These plants can effectively absorb formaldehyde and decorate the room at the same time, which is one of the in addition to formaldehyde methods commonly used in new houses.
6. Emerging formaldehyde removal methods
You can also use some emerging scientific preparations and research products to remove formaldehyde, such as the popular formaldehyde scavenger and the emerging photocatalytic decomposition method, which are effective methods to solve the harm of formaldehyde in new houses.
Matters needing attention in in addition to formaldehyde after the renovation of the new house
After the renovation of the new house, the key removal object of formaldehyde should be the bedroom. As a bedroom where people rest and sleep, the prevention and control of formaldehyde is particularly important.
Even if the odor is eliminated, it does not mean that the house is safe. Everyone can use the renovated house and still produce some odorless and harmful gases. Therefore, it is more appropriate to live after 3 months of renovation. The above content is about how to in addition to formaldehyde after the renovation of the new house, which was introduced by Tianjin Pioneer Decoration. I hope I can help you.
Formaldehyde mainly exists in chemical glue and mainly comes from the following channels:
1, decoration will use a lot of plates, such as cabinets, wine cabinets, wooden doors, tables and chairs.
2, sofa cushions and other furniture, and even some fabric toys have formaldehyde.
3. Wallpaper or latex paint.
Therefore, we must choose environmentally-friendly and formal factory products. Don't think that we will move in immediately after renovation. We think that the high-speed volatilization period of formaldehyde is half a year, and sometimes it will take several years to finally evaporate.
