In winter, the doors and windows of the room are often closed. The indoor air is dirty because it cannot be fully exchanged with outdoor fresh air, and contains more microorganisms. In addition, it can also increase the content of indoor flue gas, carbon dioxide, carbon monoxide, radon, ozone, etc., which will harm the baby's health to varying degrees. Therefore, the disinfection of the room should be strengthened frequently.
Indoor disinfection in winter can start from the following four aspects:
【1】Open the windows in the living room every day for ventilation
If you wake up in the morning and before going to bed late, open the doors and windows for half an hour to ventilate the indoor air. The survey shows that every breathing time, 60% of the original microorganisms in the air can be removed.
【2】Indoor installation of ultraviolet lamps
If 26mdash per 10%; 1 30W low-ozone ultraviolet lamp is installed in 15 square meters. If irradiation is more than 1 hour, it can kill about 90% of the microorganisms in the indoor air.
【3】Indoor disinfection by chemical fumigation
Can be fumigated with peracetic acid and vinegar. During disinfection, inject the medicine liquid into a heat-resistant and corrosion-resistant container as needed, and heat it on an electric furnace, coal furnace or alcohol furnace to make it vaporized, and the liquid evaporates, and calculate the disinfection time. When the temperature is above 15°C and the relative humidity is above 60%, use 1 gram of the medicinal solution per cubic meter and fumigation for 1 hour to disinfect the air. When disinfecting, be careful to cover items that are afraid of corrosion to avoid damage. Ventilate for half an hour before entering.
【4】Indoor ignite disinfection and sanitary incense
The main ingredients of this type of disinfection incense are Chinese herbal medicines such as pyrethra, Atractylodes, and mugwort. When using it, light incense and 1 plate in one room.
