Dust mask machine manufacturers tell the dust damage to the human body
Pneumoconiosis refers to a disease characterized by pulmonary fibrosis caused by inhalation of productive dust during the production process. A different degree of damage occurs because the quality and amount of inhaled dust are different. There are many varieties of pneumoconiosis, among which 12 are classified as occupational diseases. They are: silicosis, coal worker's pneumoconiosis, graphite pneumoconiosis, carbon black pneumoconiosis, asbestosis lung, talc lung, cement lung, mica lung, potter's pneumoconiosis, aluminum pneumoconiosis, electric welding. Mixed pneumoconiosis, castor pneumoconiosis.
The dust mask machine manufacturer mentioned that the chemical composition of dust is one of the main factors in selecting the size of the human body damage. To understand the damage of dust, the dust mask machine should know whether the dust is rich in toxic substances, radioactive substances and free. What is the silica content? Because the higher the content of free silica in the dust, the more the human body inhales, the faster the development of the lesion, and the more severe the degree of fibrosis. Therefore, it is particularly important to know the amount of dust free silica. Damage to the human body caused by different types of dust:
(1) Dust, a dust rich in free silica, such as quartz, can cause pulmonary fibrosis after inhalation.
(2) Asbestos dust can occur asbestos lung and induce lung cancer and stromal tumor.
(3) Radioactive dust, such as uranium ore dust, can cause radiation damage and induce lung cancer.
(4) Toxic dust, such as lead dust, cadmium, manganese, chromium and other metal dust, can occur in a variety of poisoning performance.
(5) Harmful dust, such as coal dust, cement dust, etc., can cause pulmonary fibrosis.
2. Dust stagnation
Some metals (iron, bismuth, tin, etc.) can be reacted with foreign matter in the lung arrangement and continue to be fibrillated, but the damage to the human body is small. After the dust operation, the lesions can gradually decline.
3. Pulmonary lesions caused by organic dust
Organic dusts include vegetal, animal and artificial organic dust. More common are cotton, tobacco, flour, sawdust, feathers, skin, fuel, plastic, asphalt and so on. Different organic dusts have different biological effects, such as bronchial asthma, cotton dust, occupational allergic pneumonia, and mixed pneumoconiosis.
4. Respiratory system
Part of the effect of dust refers to the effect of dust on the respiratory mucosa causing atrophic lesions; in addition, it can also constitute pharyngitis, laryngitis, bronchitis, etc.; the effect on the skin can constitute acne, folliculitis, pyoderma, etc.; metal and abrasive dust can be Causes damage to the cornea, causing corneal contact relaxation and corneal opacity; asphalt smoke can cause photo-induced dermatitis under sunlight.
