MINERAL FIBRE PRODUCTS

The properties of mineral fibres comprising silicon, magnesium, calcium, iron, aluminium and oxygen atoms are improved by exposure to a heat treatment under oxidising conditions which causes migration of MgO, thereby creating an outer layer with increased concentrations of MgO.

More Information
Summary:The properties of mineral fibres comprising silicon, magnesium, calcium, iron, aluminium and oxygen atoms are improved by exposure to a heat treatment under oxidising conditions which causes migration of MgO, thereby creating an outer layer with increased concentrations of MgO. Batts and other fibrous products containing the fibres have increased resistance to shrinkage and sintering. On améliore les propriétés de fibres minérales comprenant du silicium, du magnésium, du calcium, du fer, de l'aluminium et des atomes d'oxygène, en les exposant à un traitement thermique dans des conditions d'oxydation, ce qui induit la migration de MgO et la création d'une couche extérieure à concentrations accrues de MgO. Les plaques et autres produits fibreux contenant ces fibres possèdent une résistance accrue au retrait et au frittage.
