The materials used for interior decoration are harmful to toxic pollutants and pollute the indoor environment. This kind of indoor pollution from the decoration itself is called home decoration pollution. If the content of pollutants in the home decoration is too high, and it will not be solved for a long time, it will cause physical discomfort and affect health. How to get rid of the pollution in the home decoration? Xiaobian to teach you a few tricks.
Part1: Commonly contaminated formaldehyde in home decoration
With the development of the economy and the improvement of people's living standards, various raw materials have been built into the family. The representative of indoor air pollution is recognized as the chemical substance formaldehyde.
Home environmental protection knowledge to get rid of pollution
Introduction of formaldehyde
The main hazard of formaldehyde is the stimulating effect on the skin and mucous membranes. Formaldehyde is a protoplasmic toxic substance, which can bind to proteins and cause severe respiratory irritation and edema, eye irritation and headache when inhaled at high concentrations.
Household formaldehyde pollution index
The decoration of family rooms should be based on practicality and simplicity, and over-decoration may lead to the superposition effect of pollution. Over-renovation is not necessary. Once there is a quality problem in the lower blockboard, formaldehyde and other toxic and harmful gases will spread and release through the upper solid wood floor. The limit of free formaldehyde in the room: the maximum allowable concentration in the public place is 0.12mg/m2; in the living room is 0.08mg/m2.
Choose building materials to get rid of formaldehyde pollution
Some insulation materials, foam insulation materials, wood plywood, fiberboard, floor glue, carpet, wallpaper, paint, plastic wall skirt, floral decoration, floor and paving, and connecting adhesive all contain formaldehyde, which should be carefully selected.
How to remove formaldehyde from new homes
1. Activated carbon adsorption method: put three to five discs of enough activated carbon in each corner of the house.
2, ventilation removal method: open the doors and windows to allow the air to naturally circulate.
3. Plant method: It is appropriate to place 2-3 pots of 1.5-meter-high plants in the room.
4, professional team governance: professional team uses a variety of professional instruments and methods to remove formaldehyde from household residues
Part2: Commonly contaminated diphenyl in home decoration
In addition to formaldehyde pollution, the second biggest killer of household pollution is benzene pollution. When a person inhales a high concentration of toluene or xylene in a short period of time, symptoms of central nervous anesthesia may occur, and severe respiratory failure may occur.
Introduction of benzene
Benzene is mainly used in interior decoration coatings, wood lacquers, adhesives and various organic solvents. Benzene can cause leukemia and aplastic anemia is also recognized by the medical community. Patients who inhale excessive benzene may have dizziness, nausea, chest tightness, fatigue, severe coma and even death due to respiratory and circulatory failure. Chronic benzene poisoning may have irritating effects on the skin, eyes and upper respiratory tract.
Household benzene pollution indicators
The benzene in households and office buildings mainly comes from the use of a large number of chemical raw materials in architectural decoration, such as paints, fillers and various essential solvents, which contain a large amount of organic compounds, which are sent to the interior after renovation. Some of the raw materials can make the indoor air benzene content more than 14.7 times the highest allowable concentration in the country. The indoor air benzene content should not exceed 0.09/m2.
Choose building materials to get rid of benzene pollution
Choosing some water-based wood lacquer is the fundamental way to prevent and reduce benzene pollution in home interior decoration. Be careful not to seal the bottom of the wall with paint. This is a process that seriously pollutes the indoor environment and causes long-term benzene pollution problems. Do not use furniture made of inferior large core or MDF. It releases formaldehyde or benzene in large quantities over a long period of time.
How to remove benzene from new homes
After the renovation of the living room, keep the house in a good ventilation environment, such as the use of an effective indoor air purifier and air ventilator, or open the window when the outdoor air is good, which is beneficial to the indoor benzene emission and discharge Wait until the benzene is released for a while before living. If you find that indoor air pollution is serious, you can also ask the experts of the indoor environmental testing center to conduct indoor air quality testing on the renovated houses in order to take appropriate measures.
