Porosity analysis of three types of balsa (Ochroma pyramidale) wood depending on density

Balsa (Ochroma pyramidale), which is the lowest density wood, is a useful species in various industries. In general, balsa can be divided into three types (low density: LD, middle density: MD, high density: HD). In this study, we classified the porosities of the three balsa types into through-pore porosity, blind-pore porosity, and closed-pore porosity. As a result, the total porosity of balsa showed a high positive (+) correlation with closed-pore porosity, but total porosity of balsa showed negative (-) correlations with blind-pore porosity and through-pore porosity. Such information can be useful when using balsa as a natural porous material.

Automated summary

The study classified the porosities of balsa into three types and found that total porosity of balsa is positively correlated with closed-pore porosity and negatively correlated with blind-pore porosity and through-pore porosity. This information is useful in utilizing balsa as a natural porous material.
