Ant aldehyde test
Formaldehyde detection is the process of detecting formaldehyde concentration in indoor air. There are two common detection methods:
1. Instrument detection method
Instrument detection method refers to the use of professional formaldehyde detection instruments to determine whether there is formaldehyde pollution in the room by measuring the concentration of formaldehyde in the air. This method has high accuracy, but it needs professional operation and the detection cost is high.
2.DIY detection method
DIY detection method refers to the use of self-purchased formaldehyde detection box to judge whether there is formaldehyde pollution in the room through the discoloration of reagents in the box. This method is simple in operation, low in cost, but low in accuracy.
Formaldehyde treatment
If the test results show that there is formaldehyde pollution in the room, formaldehyde treatment is needed. Common governance methods are as follows:
1. Ventilation method
Ventilation means to exchange indoor air with outdoor fresh air by opening windows and installing fresh air systems, so as to reduce indoor formaldehyde concentration. This method is simple, but we need to pay attention to the weather and the temperature difference between indoor and outdoor.
2. Activated carbon adsorption method
Activated carbon adsorption method refers to the use of activated carbon and other adsorbents to adsorb indoor formaldehyde and reduce indoor formaldehyde concentration. This method is simple and effective, but the adsorbent needs to be replaced regularly.
3. Ultraviolet photolysis
Ultraviolet photolysis refers to the photolysis of indoor formaldehyde with ultraviolet lamp and its decomposition into harmless substances. This method has obvious effect, but we should pay attention to the safe use of ultraviolet lamp.
