Anonymous users2024-02-06Indoor air pollution is not only formaldehyde, but also benzene, toluene, xylene, ammonia and TVOC, but formaldehyde is more familiar because it is a class I carcinogens.
There are only two effective ways to remove decoration pollution: ventilation and professional treatment.
No matter what method is used to remove decoration pollution, the first thing to understand is the degree of pollution. Because the quality of the decoration materials used in the decoration process is uneven, even if all the decoration is made of environmentally friendly materials, it should be tested before moving in. Understand the degree of pollution in your home and then choose a reasonable removal method.
It must be said here that you must find a formal testing agency to do decoration pollution testing, the data error of the test box and handheld detector is very large, **News has also been reported, you can search on Tencent**: Is self-testing formaldehyde reliable? ）
Let's talk about ventilation first, this method is only suitable for houses that are not seriously polluted, if the multiple of the excess is too high, don't ventilate, and it may not be able to meet the living standard for two years. Although ventilation does not cost money, it is more time-consuming and laborious, and the house is vacant for a long time, so it is not recommended to use this method if you are in a hurry to move in. Moreover, it must be ventilated for a long time to have an effect, and the formaldehyde release cycle in furniture is as long as 3-15 years.
We must be prepared for a long-term battle with formaldehyde.
There is also a way is professional governance, indoor home environmental protection has matured after years of development, but there are fish in troubled waters in every industry. The following will introduce you to the commonly used treatment technologies of formaldehyde treatment companies in the market.
The first generation of formaldehyde removal technology: high-temperature fumigation.
Using the volatile characteristics of formaldehyde, benzene and other pollutants, the furniture is fumigated to increase the surface temperature of the furniture to 100-200 degrees Celsius, so that the formaldehyde is released faster. This method can only accelerate the volatilization of formaldehyde on the surface of furniture, but cannot volatilize the formaldehyde in the inner layer of furniture. The effect is okay in the short term, but the formaldehyde inside the furniture will be slowly released over time.
The second generation of formaldehyde removal technology: photocatalyst.
Photocatalyst is a catalyst that can decompose harmful organic compounds such as formaldehyde, toluene, and TVOC into harmless gases under the action of ultraviolet light, so as to achieve the purpose of removing formaldehyde. It is important to remember that the photocatalyst needs to react in the presence of light, and the more light it is, the better. However, in poor lighting or shady corners, the effect of this method in removing formaldehyde becomes limited.
The third generation of formaldehyde removal technology: air catalyst.
Like a photocatalyst, it is also a catalyst, but the difference is that the reaction medium of this catalyst is air. As long as it is in contact with the air, it can decompose harmful pollutants such as formaldehyde, benzene, toluene, xylene, ammonia, and TVOC. This solves some of the limitations of photocatalysts, and it can be said that the effect of governance is more thorough.
Moreover, the air catalyst agent will form a protective film on the surface of the furniture, which can prevent the continuous release of formaldehyde in the deep layers of the furniture.
Effective.
Photocatalysts are really useful in removing formaldehyde. Photocatalysts, also known as photocatalysts, originated in Japan at the earliest. When the photocatalyst absorbs ultraviolet and visible light, the pollutants in the air are adsorbed to the surface of the photocatalyst and will be oxidized into carbon dioxide and water to purify the air. >>>More
First of all, photocatalyst formaldehyde removal is indeed highly recognized in the industry and is the most widely used, but its disadvantages cannot be denied. It is understood that photocatalyst materials originated from Japan, but Japan was not used at home at that time, only used outdoors, that is, there was a fear that there would be secondary pollution, the reaction was not sufficient, and sufficient ultraviolet light was needed. >>>More
Photocatalyst is actually a kind of photosemiconductor technology with a certain photocatalytic effect through titanium dioxide-based nanomaterials, and its principle is to produce a photocatalytic reaction similar to photosynthesis under the illumination of light. In this way, it produces highly oxidizing substances, such as reactive oxygen species, and oxidizes and writes organic pollutant gases such as formaldehyde through redox reactions to generate carbon dioxide and water, thereby reducing indoor decoration pollution. This technology is recognized by the World Health Organization, not only lasts for a long time, has no taste, and does not need to worry about the secondary generation of decoration pollution.
Photocatalyst is commonly used to remove formaldehyde materials, under light conditions, it will produce a photocatalytic reaction similar to photosynthesis, produce free hydroxide groups and reactive oxygen species with strong oxidation ability, have a strong photoredox function, can oxidize and decompose various organic compounds and some inorganic substances, can destroy the cell membrane of bacteria and solidify the protein of the virus, can kill bacteria and decompose organic pollutants, and decompose organic pollutants into non-polluted water and carbon dioxide, so it has strong antibacterial, deodorant, mildew, antifouling and self-cleaning, The function of purifying air and water. >>>More
