What are the dangers of sound insulation cotton?

In our daily life, everything has its advantages and disadvantages, and sound insulation cotton is no exception. Sound insulation cotton is not uncommon in our lives. For example, using heat insulation cotton in the car can achieve a good insulation effect, reduce the temperature inside the car, protect the car paint, etc. But, doesn’t it have certain hazards of its own? So, let us learn about the dangers of sound insulation cotton.

Whether in the process of home decoration or in car noise prevention measures, many people use sound insulation cotton. If the sound insulation cotton can be well enclosed in a space separated from people, then the sound insulation cotton can play a good sound insulation effect and will not cause any harm to people. However, if the sound insulation cotton is accidentally exposed and we do not understand the harm of the sound insulation cotton, we will suffer a great loss. Today, I will tell you about the harm of sound insulation cotton.

Affects lung function

People who have long-term contact with glass wool, rock wool, and mineral wool will find foreign objects in their breasts when taking chest X-rays in the hospital. This is generally known as pneumoconiosis. The FVC (forced expiratory volume) in spirometry was lower than normal, but far less severe than that of asbestos workers. Pathological examination of lung biopsy of workers exposed to fiberglass showed that there were fiberglass dust cell foci, mild collagen hyperplasia, lung cancer and lung abscess in the lung tissue. When exposed to lower concentrations (2.5 atoms/ml), there was little change in workers' lung function even for 20 years. Workers exposed to high concentrations of fiberglass dust have experienced upper respiratory tract symptoms and asthma. Glass fibers with a thickness of 0.5 and 0.7 μm can be detected in the patient's lung lavage fluid.

An owner told the editor about her concerns. Because she was planning to decorate her newly bought house recently, she was hesitant about whether to use bricks or gypsum boards for the distance walls. Later I found that someone mentioned that the sound insulation cotton used in the middle of the gypsum board was harmful, so I paid attention to it. This really scared her, because sound insulation cotton is made of asbestos, which is also the material used in general sound insulation cotton.

The damage of sound insulation cotton is classified as dust

The editor tells you that the harm of asbestos used in sound insulation cotton to the human body belongs to the category of dust. It attaches to the human respiratory system, which will cause damage to the human respiratory immune system over time, and eventually a large number of asbestos particles will accumulate in the lungs, causing pneumoconiosis.

Asbestos is extremely harmful to the human body because its fibers are very fine and can be easily inhaled, directly causing lung diseases, lung calcification and the like. Moreover, its impact does not appear in a short period of time, but generally accumulates gradually over a long period of ten to twenty years.

Such a long-term ambush will make many people who know about the harm of asbestos relax their vigilance, but if we do not pay attention to prevention, then in ten or twenty years, I am afraid that a large number of people will become ill or even die in a relatively concentrated manner. This may be more obvious among workers who often come into contact with such materials.

Of course, the editor has said so much not to tell you to prohibit the use of sound insulation cotton. In fact, as long as we use appropriate methods to completely separate the sound insulation cotton from people, so that the asbestos particles are enclosed in a certain space, we can also enjoy a healthy home life while ensuring the sound insulation effect. Having said so much, the editor still hopes that everyone can recognize the harm of sound insulation cotton and take preventive measures as soon as possible.
