These three milling conditions all affected the B2O3 activity more or less, as evidenced by the changes of B2O3 activity with these milling factors.
In addition to those influencing factors, the mass ratio of balls to sample, the diameter of milling balls, and filling ratio of samples also have significant effects on the physicochemical properties and activity of the products [8,11].

In general, the mechanical properties decrease with amount of water absorption.
Also, the mechanical properties of parts can be changed accordingly.
Also, as the aging temperature increased, the amount of water absorption increased and so the mechanical properties decreased.
Also, the amount of crystallinity which is affected by the fibers will be a another factor affecting moisture absorption.
