Carbonization processes in wood-magnesia composites
Santrauka
The investigations carried out [1] revealed the changes in microstructure of magnesia compositions, including in addition anhydrite and filler such as wood shavings. In the process of hydration of magnesium oxide in the combination with fluoride-anhydrite and magnesium chloride in composition, magnesium oxychlorides with different morphology depending initial components are formed. The structure examination after 9 years of products exploitation showed the intensive carbonization of magnesite hydration products with the formation of magnesium hydrooxicarbonates that facilitated the material water-resistance.
