Ecological structure: production of organic impregnation material from mussel shell and combustion

Abstract

In the research, sea mussel shell (Chamelea gallina) powders were impregnated on the samples of Eastern spruce (Picea orientalis (L.) Link.) and Anatolian chestnut (Castanea sativa Mill.) by dipping method at different concentrations (1%, 5%, 10%, 15%). To investigate the level of use in the wood industry and especially its effects against fire; adhesion, thermogravimetric analysis (TGA), limiting oxygen index (LOI) test measurements were carried out. According to the TGA results, while the residue quantity in the spruce wood sample was the highest at 5%, the residue amount in the chestnut wood sample was the highest at 15%. With increasing amounts of mussel shell powder, the limiting oxygen index values in both wood species samples increased. As a result, it was discovered that impregnating wood samples with mussel shell powder improved the wood's fire resistance.

Enhancing Surface Characteristics and Combustion Behavior of Black Poplar Wood through Varied Impregnation Techniques

“…The choice of fire-retardant chemicals is a critical determinant of the efficacy of wood impregnation. Fire retardants can be categorized into several classes, including inorganic compounds, organic compounds, and intumescent agents [35][36][37][38]. Inorganic fire retardants, such as ammonium phosphate and aluminum hydroxide, work by releasing water vapor when exposed to heat, thereby reducing the wood's temperature and retarding combustion.…”
