▲ “If you want to remove aldehydes, please re-recognize formaldehyde”~
Formaldehyde is the “roommate” of each of us. Formaldehyde is a colorless, irritating gas that is carcinogenic and teratogenic. Since formaldehyde is a raw material for the manufacture of synthetic resins, paints, plastics, etc., the materials used in interior decoration or furniture will inevitably use formaldehyde. What many people don’t know is that formaldehyde poisoning usually lasts for 3-15 years. Even if our house is decorated for a long time, it is very likely that there is a danger of formaldehyde. In 2013, Tsinghua University investigated the formaldehyde status of 40 households in Beijing. These families have not been renovated in 2 years, and 12.5% of households still have excessive formaldehyde. Moreover, the volatilization rate of formaldehyde is greatly affected by temperature, and the volatilization rate of formaldehyde is faster when the temperature is high.
If it is in the environment with excessive formaldehyde for a long time, it will cause fatal chronic damage to the human body. Especially, children have different blood characteristics from adults, hematopoietic function is unstable, and hematopoietic reserve is poor, which is more likely to cause organ infection. Lack of nutrition and other conditions. Formaldehyde has a strong stimulating effect on the skin and mucous membranes. When inhaled at high concentrations, the human body may have severe respiratory irritation and edema, eye irritation, headache, allergic dermatitis, bronchial asthma and even cancer.
In particular, many people still rely on the nose to judge whether the formaldehyde exceeds the standard, and when we can smell the obvious formaldehyde smell, the formaldehyde has exceeded the standard by at least 2 times! Therefore, judging formaldehyde by the nose is like judging smog by the eyes, and it is already very serious.
▲ What is the formaldehyde detection method?
We can easily find a lot of formaldehyde detection props on the Internet, ranging from a few dollars to tens of thousands. The detection principle of the civil formaldehyde detector is mostly detected by a semiconductor gas sensor and an electrochemical method, and the detection accuracy is easily disturbed by organic volatile substances (such as water vapor, cosmetics, etc.) in the environment.
At present, the more accurate formaldehyde detection method on the market is the spectrophotometric and meteorological chromatographic detection methods. We can conduct on-site inspection through a professional formaldehyde detection mechanism that can issue CMA test reports. The detection method is to report the detection data of formaldehyde, benzene, toluene, xylene and TVOC at a certain “point” in the room.
▲ How is the aldehyde removal method reliable?
In summary, the most convenient and effective 5-point aldehyde removal method under the current technical means is only one–long-term ventilation.
The unobstructed indoor air can effectively reduce the content of harmful substances in the air, which is the most direct and effective way to reduce air pollution. The longer the ventilation time, the better. The ventilation area is set according to the indoor space area. The circulation of indoor air is relatively straight and the path of air in and out is relatively straight. The long-term ventilation methods include [long-term window opening] and [installing fresh air].
However, in the case of air pollution, air conditioning or outdoor noise in summer, and large dust, we cannot guarantee continuous window ventilation. Therefore, the installation of fresh air system has become a passive and active aldehyde removal method.
When choosing a fresh air system or a new wind turbine, you need to consider the actual building area of your home and choose a new wind turbine with the right air volume. According to the “Residential Design Code” (GB50096-2001) 8.6.4, the number of residential air changes should be guaranteed once / h. You can judge whether the selected fresh air is appropriate according to the formula W>S·h. Where W is the fresh air volume per hour of the fresh air system, S is the floor area, and h is the floor height. For newly renovated houses, it is recommended to increase the frequency of ventilation and accelerate the dilution and discharge of formaldehyde.
Choose the fresh air with the lowest noise possible under the right air volume. If you have anti-fog, anti-allergic sources, outdoor ozone removal, etc., you need to choose high-efficiency HEPA filter, ozone filter and multi-unit filter structure according to your needs. New fan.
▲ Vtronic fan Fresh air series
The high-efficiency three-layer filter system is divided into three layers of filters, the first layer is the initial effect, which can filter mosquitoes, hair, large particles of dust and other substances; the second layer is activated carbon filtration, mainly to filter various odors in the air; The third layer is HEPA mesh filtration, which can filter PM2.5 and other micro-particles; Vtronic wall mounted fan adopts multi-layer folding composite filter, its internal small micro-holes have strong ability to capture particles, long-term purification, greatly reduce wind resistance and increase fresh air. The output will bring you more fresh and oxygen-rich air.
