Everyone knows that we want to stay as soon as possible after the renovation. We must consider how to deal with the problem of formaldehyde in the newly renovated house. Why is the newly renovated house going to formaldehyde? Some friends may not know this new decoration. The reason for the house to go to formaldehyde is that some formaldehyde will be harmful to the body after staying indoors. So what are the good ways to get formaldehyde from our newly renovated house?
First, the need to remove formaldehyde
1. First of all, the formaldehyde in the living room mainly comes from the use of various artificial boards, including artificial boards such as plywood, blockboard, medium density fiberboard and particle board used for interior decoration, furniture made of artificial board, artificial board floor and wooden floor. Secondly, there are other kinds of decorative materials, such as curtains, wall coverings, wallpapers, chemical fiber carpets, and foams, which contain formaldehyde and are likely to be emitted to the outside world. Third, various coatings, including solvent-based coatings (ie, paints) and water-based coatings (commonly known as coatings).
2. Formaldehyde is a colorless, highly irritating gas. Soluble in water, alcohol and ether. Formaldehyde is gaseous at normal temperature and usually appears as an aqueous solution. 35 to 40% of the aqueous formaldehyde solution is called formalin. There is an aldehyde group polycondensation reaction in the formaldehyde molecule, and a phenol resin (bakelite) can be obtained. The main hazard of formaldehyde is the stimulation of the skin and mucous membranes. When formaldehyde reaches a certain concentration in the room, people have discomfort. The concentration of formaldehyde greater than 0.08m3 can cause redness, itchy eyes, sore throat or pain, hoarseness, sneezing, chest tightness, asthma, dermatitis, etc.
Second, the method of removing formaldehyde
1. Put salt water in the new house
Using the solubility of formaldehyde in water, we can put a few pots of salt water in each room, so that we can initially absorb a lot of pungent smell in the room.
2, indoor ventilation
Everyone knows that formaldehyde is a volatile substance, so we can use this to open the doors and windows of the room to keep the air convection inside and outside the house, so it will be almost two months or so. But this method must be Be careful to remember to close the doors and windows at night to avoid being stolen.
3, indoor temperature is raised
The rate of volatilization of formaldehyde is generally very slow. If we want to make it volatilize as soon as possible, we should try to increase the temperature of the room as much as possible. We can turn on the air conditioner to raise the room temperature to accelerate the volatilization rate of formaldehyde.
4. Adsorption of activated carbon, etc.
We can use some things that can have a strong odor adsorption function to improve indoor air quality. At present, the most popular activated carbon on the market is available. About 50g of activated carbon per square meter can promote formaldehyde. However, it should also pay attention to the replacement of activated carbon, generally 7-8 months is appropriate.
