retention correlate well with resistance to acid degradation as measured by strength retention. the relationship between these two pentosan values and alkaline degradation is weaker, but still significant. hemicellulose retention is a better indicator of the behavior of wood with respect to alkaline attack. the most useful, Free Sample

exterior glue lines are more chemically resistant to most acids and bases, solvents and petroleum than the wood. plywood does, however, accept pressure , dilute alkaline solutions: dilute solutions will weaken wood, the rate being dependent upon temperature and alkalinity. cold dilute alkali solutions will weaken wood, Free Sample

the ph scale measures how acidic or alkaline a substance is. substances with a ph of 7 are neutral, substances with a ph greater than 7 are alkaline (or 'basic') and substances with a ph lower than 7 are acidic. alkalis are 'bases' that are soluble in water. (all alkalis are bases but not all bases are alkalis.), Free Sample
