What is the harm of ammonia gas polluted by decoration
When ammonia is inhaled into the lungs, it is easy to enter the blood through the alveoli and combine with hemoglobin to destroy the delivery of oxygen. The solubility of ammonia is very high, so the upper respiratory tract of animals or people is mainly irritating and corrosive, which weakens the resistance of human body to diseases.
Forms of ammonia pollution in decoration
Ammonia irritant is a reliable alarm signal of harmful concentration. However, due to olfactory fatigue, long-term exposure to low concentrations of ammonia is difficult to detect. Inhalation is the main mode of contact, and the manifestations of inhalation ammonia poisoning mainly include the following aspects. The symptoms of slight inhalation ammonia poisoning are rhinitis, pharyngitis, sore throat and hoarseness. Ammonia into the trachea, bronchi can cause coughing, expectoration, sputum with blood. Severe hemoptysis and pulmonary edema, dyspnea, cough white or bloody sputum, two lungs full of big, middle bubble sound.
As mentioned before, the use of concrete admixtures containing ammonia will cause ammonia pollution to the indoor air and affect human health. After knowing the source, harm and manifestation of ammonia, the following Dongguan decoration network will share the prevention and control of ammonia pollution:
1. Effective detection: after the decoration of the room, when there is strong odor after ventilation for a period of time, please ask a professional testing company to detect, and take corresponding measures in time according to the test results.
2 frequent ventilation - when it is detected that the ammonia in the room does exceed the standard, the general room will adopt the method of window ventilation to reduce pollution, which is an economic and practical method. However, in the closed design of the top-grade office building, the ventilation condition is very poor. There are no windows for the large area glass curtain wall to open, even if the windows are limited, it is difficult to achieve the purpose of ventilation. At this time, air heat exchanger can be installed to ventilate frequently.
3. Source control: strictly control the ammonia content released by the concrete admixture during the construction to make it meet the standard requirements, and control from the source is the best prevention and control measure for ammonia pollution.
Selection of purification device - anion purifier
The principle of anion air purification is neutralization and precipitation. Ecological level (small particle anion) can actively capture the small particle dust, make it coagulate and precipitate, and effectively remove the air dust of particles below 2.5 μ m, even 1 μ M. The negative ions produced by the technology of ecological negative ion generation chip are small in size and high in activity, which can automatically spread to all corners of the room without external fan purging, without noise and dead angle purification.
