설명

일반 설명

Glass wool is a fibrous inorganic substance (silicates) made primarily from rock, slag, glass, or other processed minerals. It is widely used as a thermal insulation material.
Glass wool plugs are often used in GC inlet liners to improve sample vaporization and to keep non-volatile material from entering the column. They can also be used in packed GC columns, solvent desorption tubes, thermal desorption tubes, and purge traps to retain adsorbent beds.

애플리케이션

• Assessment of different factors on the influence of glass wool concentration for detection of main swine viruses in water samples: This research demonstrates the use of glass wool in the filtration and concentration of viruses from environmental samples, contributing significantly to public health safety and environmental monitoring (Fan et al., 2023).


• The Evolution of Insulation Performance of Fiber-Reinforced Silica Aerogel after High-Temperature Treatment: Research on glass wool′s effectiveness in thermal insulation and its durability under high temperatures is essential for its application in high-performance building envelopes and industrial installations (Gao et al., 2023).
