Spring familyAir sterilizationLate spring and early summer, the temperature is cold, bacteria, virus propagation time. Therefore, family air disinfection is particularly important. Here are some disinfection methods.1. peracetic acid fumigationPeracetic acid is a fast, effective and broad-spectrum disinfectant. Its dosage is calculated by 1 grams per cubic meter volume. Room closed, room temperature above 18 degrees is appropriate. Place the liquid in the enamel container. Be careful not to splash on metal objects or terrazzo surfaces to prevent corrosion.2. Mugwort FumigationLeaves also called mugwort, it contains 0.02% volatile oil, the main ingredients of eucalyptol. The test proved that the antibacterial effect of eucalyptol were anthrax, hemolytic streptococcus, bacillus, Streptococcus pneumoniae, Staphylococcus aureus and Bacillus subtilis. According to the volume of the room, every 1 cubic meters need 1 grams of dried mugwort leaf, calculate the amount of moxa leaf needed, put it into the iron container to ignite, and let the smoke in the room diffuse, until the mugwort leaves burnt out into ashes. This method is easy to operate, and cheap and good, basically no irritation to the human body.
Source IP:Indoor air testing is generally carried out 7 days after the housing renovation, and furniture has not moved into housing. This is because when the house has just been decorated, it is the most serious time for indoor air pollution. When the air test, furniture can not move into the housing, the reason is that if the furniture itself contains formaldehyde gas, it is not clear whether the decoration caused by indoor air pollution, or furniture release of air pollution. Before conducting indoor air testing, close doors and windows according to different requirements of the inspection items. For example, formaldehyde, benzene, ammonia, TVOC testing, to close doors and windows 1 hours; radon detection, to close windows and doors 24 hours. When the air sampling, there is a centralized air conditioning system (that is, central air conditioning) to be opened, the civil air conditioning to be closed, the system remains the same as normal.Indoor air testing must find third parties, impartial, authoritative testing department, because the air test technical requirements are very high, without professional training personnel, is unable to detect standards. If necessary, the local quality inspection or environmental protection departments can be consulted and tested.
Testing,,,I've got some materials. I wonder if I can help youI hope I can help youWhat is asbestos?Asbestos is a mineral fiber. It is certain that only a special microscope has been identified. There are several types of asbestos fibers.

Inhalation of asbestos fibers is greater, if you smoke. People usually get highly asbestosis asbestos by a long time. The symptoms of the disease usually does not appear first contact with asbestos is about 20 to 30 years.Most people come into contact with a small amount of asbestos, everyone in our daily life, will not have these health problems. However, if the interference, can release the asbestos fiber asbestos material, it can be inhaled into the lungs. This fiber can be dangerous to stay there long illness.
