Formaldehyde, also known as anthranilic aldehyde. The colorless gas has a special irritating odor, and has an irritating effect on human eyes and nose. Formaldehyde's main hazard is to irritate the skin and mucous membranes. Formaldehyde when the indoor concentration reaches a certain level, people will feel uncomfortable. Concentrations greater than 0.08m3 can cause flushing, itching, sore throat, hoarseness, sneezing, chest tightness, asthma, etc. High levels of formaldehyde in newly renovated rooms are the main cause of many diseases. Long-term exposure increases the risk of specific cancers, such as Hodgkin's lymph, multiple myeloma and myeloid leukemia.
Each of us spends roughly 85% of our day working indoors, so if the indoor air quality is poor, it may affect our quality of life as well as our work efficiency, so we can live indoors with confidence if we can effectively do the monitoring of the indoor air quality, and the assessment of the risk of harm and take responsive and proactive measures.
For example, many people will use the air quality detector to monitor the air quality situation, comprehensively protect the home of pregnant women, children, the elderly and coworkers health. For example, Shenzhen Xenawei's formaldehyde detector HAL-HFX105 can accurately detect the presence of formaldehyde, PM2.5, temperature and humidity data in indoor air in real time, and the internal is the use of professional detection sensors, detection data is more accurate, and the appearance of the design also encompasses a stylish simplicity of the concept of guarding every breath of freedom for us.
1, with activated carbon adsorptionActivated carbon is very effective in removing formaldehyde, but its adsorption capacity is very limited. Activated carbon generally has a certain adsorption effect on benzene. But compared with formaldehyde, the adsorption effect is less obvious, and the capacity of activated carbon will become weaker and weaker in a month.
2, ventilation methodVentilation is the easiest way to eliminate formaldehyde. This is the simplest and most effective way to discharge harmful gases directly through the air flow outdoors. But this method also has its drawbacks, that is, formaldehyde release cycle is relatively long, usually takes about 3 to 15 years. After the refurbishment and let the new house vacant for more than three years is not realistic, so rely solely on ventilation methods to eliminate formaldehyde does not meet the requirements.
3, with formaldehyde removerWith formaldehyde clean disinfectant, the method relies on a chemical reaction that basically reduces the toxicity of the target substance or transforms it into a non-toxic substance. Formaldehyde can be oxidized to formic acid or reduced to methanol. Both of these substances are less toxic and irritating than formaldehyde, but the toxicity still exists. For example, some strong oxidizing formaldehyde cleaners can oxidize formaldehyde, but they break down easily. Not to mention, spraying them on wood panels will directly damage the wood, and they will be ineffective within a few hours.
4, Eliminate formaldehyde with an air purifierAir purifiers are only an auxiliary and remedial function. In the case of indoor air pollution, the use of air purifiers can reduce pollution to a certain extent, but it does not mean that the residual pollutants in the air can be eliminated fundamentally. So it is difficult to eliminate formaldehyde with one method. According to the actual situation, it is best to choose several methods to eliminate formaldehyde at the same time, in order to maximize the reduction of harmful gases in the room.
