What are the hazards of aluminum powder to the human body
The main hazard of aluminum dust to the human body is damage to the respiratory system, generally the loss of the trachea and lungs, and long-term exposure will generally cause symptoms such as bronchitis and asthma. In severe cases, it can lead to aluminum pneumoconiosis. Aluminum pneumoconiosis is a long-term inhalation of aluminum powder or aluminum oxide-containing dust, which stays in the body for a long time and deposits in the lung tissue to cause lung fibrosis. Inhalation of aluminum powder into the lungs can cause aluminum pneumoconiosis, which is manifested as weight loss, fatigue and difficulty breathing. If aluminum is absorbed by the human body, it may be bad for the human brain for a long time, and it is easy to reduce the human intelligence.
Metal aluminum, alumina, aluminum-containing ore and other dust are deposited in the lungs to form dust foci, dust foci fuse, tissue cells infiltrate and form dust cell nodules, surrounded by collagen fibers and tissue cells, with a small amount of transparent substance in the center. The structure of lung tissue is destroyed, and emphysema appears. The onset of aluminum pneumoconiosis is generally slow, and the onset of service life is more than 10 years. Therefore, it is recommended that you choose to cut outdoors or ventilate. You can also protect yourself from metal dust by using a dust mask. Once the aluminum salt enters the human body, it is first deposited in the brain, which may cause brain damage and cause severe memory loss, which is a unique symptom of Alzheimer's disease.
Measures to prevent dust:
1. Technological innovation, reforming process equipment and process operation methods, and adopting new technology is a technical measure to completely eliminate dust pollution and do a good job in dust prevention. In the process reform, the first thing to do is to prevent the production process from generating dust hazards, and secondly, the measures to eliminate or reduce the hazards after the dust is generated.
2. Wet dust prevention This is a simple, economical and effective dust prevention measure. When dust meets water, it is easy to absorb, condense, and gain weight, which can greatly reduce the generation and diffusion of dust and improve the air quality of the working environment.
3. Airtight dust source The effective sealing of the dust source is an effective technical measure to prevent dust from escaping. It is often used in conjunction with ventilation and dust removal technical measures.
