  • Detail

Decoration requires the use of various paints, which will bring toxic substances harmful to the health of residents. Just don't use paint? The wallpaper you use and the furniture you buy may contain formaldehyde and other substances. In addition to strictly controlling the environmental protection performance of building materials and furniture during decoration, decoration pollution control cannot be relaxed. The following editor introduces the simple methods of decoration pollution control

I. sources and hazards of decoration pollution

decoration pollution gases mainly include formaldehyde, benzene, ammonia and TVOC, among which formaldehyde has been identified as carcinogenic and teratogenic substances by the World Health Organization

1. Formaldehyde

formaldehyde mainly comes from indoor building materials and furniture, such as plywood, particleboard, foam filler, wood floor, wallpaper, paint and coating. The main harm of formaldehyde is to stimulate the skin and mucous membranes. Formaldehyde is a protoplasmic poison, which can combine with protein. When inhaled in high concentration, it will cause serious irritation and edema of respiratory tract, eye irritation and headache. Among all contacts, children, pregnant women and the elderly are particularly sensitive to formaldehyde, and the harm is even greater

2. Benzene, TVOC and other substances

benzene, TVOC and other substances mainly come from the adhesives used in paint, paint and furniture, which affect the central nervous system and cause dizziness, headache, weakness, chest tightness and other symptoms; Sensory irritation, uncomfortable smell, irritation of upper respiratory tract and skin

3. Ammonia

ammonia mainly comes from the antifreeze, urea, etc. added to the concrete during the construction process. In a short time, absorbing a large amount of ammonia can cause tears, sore throat, hoarseness, cough, dizziness, nausea and other symptoms. In severe cases, there will be pulmonary edema or respiratory distress syndrome, and respiratory tract irritation symptoms

II. Decoration pollution control methods

1. Simple methods

long-term ventilation (more than six months)

analysis: this kind of decoration pollution control is applicable to the decorated room with light odor, good ventilation conditions and long-term ventilation. For rooms with heavy pollution and poor ventilation conditions, it is difficult to achieve the effect of removing odor

cost: almost zero

effect: the effect of decoration pollution control is 10%~30%

2. The traditional method

uses air aromatics, bagged aromatic plants, tea, pineapple and other anti odor

analysis: air aromatics and bagged aromatic plants basically play a covering role or a psychological role, and cannot play a role in fundamentally eliminating pollution. Cost: low. Effect: no effect, just cheat the nose. Tea and pineapple have a weak effect on odor, and can be used as auxiliary products

cost: the cost of decoration pollution control is low

effect: weak

3. Plant methods

place green plants (such as Chlorophytum comosum, aloe, etc.) in the room. Some plants can absorb harmful gases

analysis: it has a certain absorption effect, and has the effect of beautifying the room, but it takes a long time to take effect

cost: decoration pollution control cost is low

effect: 10% - 30%

4. Chemical method

uses the principle of chemical decomposition reaction, and uses products such as formaldehyde capture agents on the market to remove peculiar smell. This method is applicable to the treatment of materials such as plates in the process of decoration, so as to prevent decoration pollution

analysis: if used in the decoration process, it can fundamentally solve the problem of continuous formaldehyde release, but it is easy to cause damage to human body and object surface after decoration

cost: relatively high

effect: more than 95%

recommended when economic conditions permit

5. Physical methods

use the principle of activated carbon adsorption and purification (such as air purification system) to adsorb macromolecular gas suspended particles in the air, and achieve the purpose of filtering and purifying the air through forced air circulation

analysis: the action time is long and there is energy loss. The disadvantage is that the pollution source is slowly released, and only after contacting it can it have a certain effect

cost: medium

effect: about 15%-35%, recommended as auxiliary products
