Asbestos is a silicate mineral that is generated from the mining / natural materials. Asbestos awalnyadisebut well as Mineral Magic because of its heat resistance, either as an electrically insulating, resistant to chemicals and oil.
The advantage of this material is economical and also cheap.
The use of asbestos in building materials. The use of asbestos in building materials are often used in fiber cement sheets, ceilings, roofing, partitioning, cladding, GRC,
(Glassfibre Reinforced Cement).
Insulation material or other refractory mix containing asbestos, fuse / other electrical equipment, etc.
Based on mineralogical composition, asbestos can be classified into two parts. Serpentine group, namely mineralkrisotil which is magnesium silicate hydroxide with the composition Mg6 (OH) 6 (Si4O11) H2O, amphibole, is mineral krosidolit, antofilit, amosit, actinolite and tremolit. Although it was clear mineral asbestos Consist complex silicates, but in writing asbestos mineral composition differences. Originally considered that its silicon composed of molecules Si11O12. However, based on the investigation results of X-rays, in fact, silicates consists of molecules Si4O11.
Asbestos in the automotive world is also used as ingredients in the manufacture of brake linings, clutch linings and gaskets. But we must be careful in the use of asbestos, because darihasil study mentioned that asbestos negative effect on the health of them cause asbestosis, mesothelioma and lung cancer. Asbestosis occurs when asbestos fibers are inhaled and trapped in the lung tissue. With the body’s defense mechanism, the body will produce a kind of acid to dissolve the asbestos fibers. Due to the nature of asbestos is resistant to chemicals so that the asbestos fibers are only partly dissolved and instead will make the tissue surrounding the wound. This injury which makes the lungs are not functioning properly. Mesothelioma is a cancer that occurs in the outer lining of the lung or in the outer layers of the abdominal wall. The disease is more common in the industry that many employees use asbestos raw materials, also of the people around the factory, people who often work on the street as the police and highways, mechanical and users as car repair Seeing such a huge impact on health, then the international community responded by issuing the Rotterdam Convention in September 2004 that essentially regulates the international trade of toxic pesticides and Hazardous Chemicals.
