What are the methods for pollution control of interior decoration?
1 , simple method 　　
Long-term ventilation (more than six months). 　　
Analysis: It is suitable for the renovated living room with light odor, good ventilation and long-term ventilation. For a house with a heavy pollution level and poor ventilation conditions, it is difficult to achieve the effect of removing odor.       Cost: almost zero effect: decoration pollution control effect 10%~30% 　　
2 , the traditional method 　　
Use tea, pineapple, etc. to fight off odors. 　　
Analysis: It is basically a cover-up effect or a psychological effect at all, and it cannot achieve the effect of radically eliminating pollution.
Cost: Low effect: no effect, deceive the nose.
　　 3 , plant methods 　　
Green plants (such as spider plants, aloe vera, etc.) are placed in the living room, and some plants have the effect of absorbing harmful gases. 　　
Analysis: There is a certain absorption effect, and there is also the effect of beautifying the living room, but the onset time is longer. 　　
low cost Effect: 10 % to 30 % 　　
4 , chemical methods 　　
Using the principle of chemical decomposition reaction, a product such as a formaldehyde trapping agent on the market is used to remove odor. This method is applicable to the treatment of materials such as plates during the decoration process to prevent decoration pollution. 　　 Analysis: If used in the decoration process, it can fundamentally solve the problem of continuous release of formaldehyde, but it is easy to damage the human body and the surface of the object after decoration. 　　
Cost: relatively high Effect: 85 % or more 　　
5 , physical methods 　　
The principle of activated carbon adsorption purification (such as air purification system) is used to adsorb macromolecular gas suspended particles in the air, and the purpose of filtering and purifying air is achieved by forced air circulation. 　　
Analysis: Long acting time and energy loss. 　　
Cost: Medium effect: 95 % or so
What daily measures should be taken to govern the pollution control of interior decoration?
1. Newly built houses or newly renovated rooms should not be rushed to move. They should be ventilated for a period of time to eliminate odor. Even if you live in, you still need to open the window every day to ventilate the air to ensure that there is enough fresh air in the room, and winter is no exception.
　　 2 , indoor decoration, should carefully choose the construction, decoration materials, should not over-renovation.
　　 3. When purchasing furniture, you should choose solid wood furniture as much as possible. If you choose materials such as MDF and fiberboard, you must choose the products that have been checked and accepted by the relevant departments.
　　 4 , try to avoid fried foods when cooking, stir fry or fry should also try to shorten the time. When cooking, you should turn on the hood or open the window to change the air to reduce indoor air pollution caused by burning and cooking.
　　 5 , try not to smoke indoors to reduce indoor air pollution caused by smoke.
　　 6 , try not to keep pets indoors, bedding, blankets and carpets should always be dried in the sun to avoid the rise of dust mites.
　　 7. Planting some green plants indoors can play a role in purifying air quality. For example, vines, iron trees and other absorbable benzene and organic matter, plants such as spider plants and aloe can absorb formaldehyde.
The method of indoor decoration pollution control - photocatalyst, what are the advantages and disadvantages?
Advantages: strong permeability, good adhesion, after forming an ecological film, it needs high pressure steam to destroy. When harmful gases pass through this layer of ecological film, they are decomposed, so that the air does not contain harmful air and has a bactericidal effect. Since the photocatalyst acts as a catalyst and does not decompose itself, it is effective for a long time. Combined with scavengers and decomposers to remove harmful gases that have evaporated into the air, the effect is fast and long-lasting.
Disadvantages: It is a photocatalyst, so a room without light such as KTV is invalid. There are many kinds of photocatalysts, and the results are not uniform. The research results in Japan are the most prominent. The Chinese varieties are mixed and even use oxidants instead of real photocatalysts. It is difficult to distinguish true photocatalyst products.
Interior decoration pollution of main pollutants - formaldehyde, at different concentrations What is the difference on the human body?
The national standard for formaldehyde is 0.08/m3 per cubic meter.
When the formaldehyde content in the indoor air reaches 0.06 - 0.07 mg / m3 , children will experience mild asthma.
When the formaldehyde content in the indoor air is 0.1 mg/m3 , there is odor and discomfort;
When the concentration reaches 0.5 mg/m3 per cubic meter of air , it can irritate the eyes and cause tearing;
Concentrations of 0.6 mg/m3 per cubic meter of air can cause discomfort or pain in the throat.
Higher concentrations can cause nausea and vomiting, cough and chest tightness, asthma, and even pulmonary edema;
When the concentration reaches 30 mg/m3 per cubic meter of air , it immediately kills people.
What is the effect of coconut shell activated carbon, one of the means of indoor decoration pollution control?
1 detoxification
The polymer contained in the coconut shell activated carbon can quickly distinguish TVOC and harmful gases such as formaldehyde, benzene, ammonia and hydrazine in the air, and use the combination of physical and chemical properties of activated carbon to specifically adsorb it. It releases the beneficial oxygen factor beneficial to the human body, and achieves the function of detoxifying and deodorizing and purifying the indoor air.
2 mold and radiation protection
The production of mold is closely related to the humidity of the air, and the coconut shell activated carbon under high-tech technology is just a bridge between mold and air humidity. It regulates the humidity in the air and inhibits the proliferation of mold and microorganisms. In addition, a large number of superphoton particles produced by coconut shell activated carbon can block electromagnetic waves and effectively prevent electromagnetic radiation from household appliances such as televisions, computers, mobile phones and interior appliances from harming the human body.
3 improve the overall environmental quality
Formaldehyde, benzene, ammonia, hydrazine and TVOC (volatile organic compounds) are the main sources of indoor environmental pollution, which affect the overall air quality of the indoor environment. At the same time of sterilization and deodorization, coconut shell activated carbon emits activating factor continuously, regulates indoor air quality and humidity index for 24 hours, maintains the best room temperature suitable for the human body, and creates a healthy and environmentally friendly living space.
What are the advantages of activated carbon as one of the treatment methods for indoor decoration pollution?
1. Activated carbon is an internationally recognized drug addict, activated carbon masks, and gas masks using activated carbon. This product uses the physical action of activated carbon to deodorize and detoxify; without any chemical additives, it has no effect on the human body.
2. Drug treatment such as spray is easy to cause secondary pollution, and may damage the furniture. Activated carbon is physically adsorbed, safe, harmless to the human body, and has anti-mold and anti-corrosion effects on the home.
3. Some products advocate one-time removal ( experts question, untrustworthy), and the release of poison gas in the home is a slow process, so it was removed today, and it tasted in a few days, and the price is not low. The effective adsorption period of activated carbon is 5-8 months just matching it.
4. Breathable packaging, easy to use, low price of activated carbon, can be used repeatedly under the scorching sun, easy to save, not deteriorated under sealed conditions for 5-10 years.
