mineraalikuitujen

Mineraalikuitujen, or mineral fibers, are a group of fibrous inorganic materials derived from naturally occurring minerals. They are characterized by their elongated, thread-like structure, which imparts unique physical and chemical properties. Common examples of mineral fibers include asbestos, glass wool, rock wool, and ceramic fibers.

Historically, asbestos was widely used due to its excellent heat resistance, electrical insulation, and tensile strength. However, concerns over its health risks, particularly its carcinogenicity when inhaled, have led to significant restrictions and bans on its use in many countries.

Modern mineral fibers, such as glass wool and rock wool, are produced by melting minerals like sand, limestone, and basalt at high temperatures and then spinning them into fine fibers. These materials are extensively used as thermal and acoustic insulation in buildings and industrial applications. They are generally considered safe when handled properly and have low flammability.

Ceramic fibers, made from refractory materials like alumina and silica, are engineered to withstand extremely high temperatures. They are employed in high-temperature insulation for furnaces, kilns, and in aerospace applications.

The production and application of mineral fibers are subject to regulations aimed at minimizing potential health and environmental impacts. Research continues to focus on developing safer and more sustainable mineral fiber alternatives.
