Length and width ratio of fibrous minerals is more than 3. That means their length is at least 3 times longer than their width. Asbestos minerals are also called “fibrous minerals” because of their fibrous structural properties. These minerals are resistant to heat and friction because of their structure and their fibrous structure gives them excellent insulation ability. Thanks to these properties asbestos has found widespread use in the industry in approximately 3,000 business sectors. The main fields of application are:
Asbestos in Cement Industry
- Sheet Production
- Pipe manufacturing
- Gasket manufacturing
Asbestos in Textile Industry
- Yarn production
- Fabric production
Asbestos in Paper Industry
- Paper production
- Cardboard making
Asbestos in Automotive Industry
- Clutch pad
Due to health risks the production of asbestos and its use in industry has been banned in many countries. In many countries serious restrictions have been imposed. However, asbestos produced and used until this date still takes place in every moment of our lives.
Asbestos products are used in insulating, non-flammable products productions and in cheap properties in recent years. Small asbestos fibers are mixed into the air with wear of asbestos substances. The presence of asbestos in free air a great danger to health.
The minerals considered as substitutes for asbestos are:
Research has focused on the properties to make these substances as potential substitutes. Most of these minerals are cheaper than asbestos and are easily available and have no carcinogenic effect. Minerals that can cause lung diseases are quartz, diatomite and perlite.
In some applications synthetic-inorganic substitutes containing glass fibers, mineral wool and ceramic fibers are used instead of asbestos. Glass fiber and mineral wool are more expensive than asbestos. Commercial production of these substances is common and easy to find. Some cases have shown that glass fiber and mineral wool can have carcinogenic effects.
