▁contact ▁is ▁achieved . ▁The ▁inter fa cial ▁t ensions ▁can ▁be ▁measured ▁using ▁common ▁experimental ▁techniques ▁such ▁as ▁a ▁Wil hel my ▁plate ▁or ▁the ▁Du ▁No ü y ▁ring ▁method ▁to ▁predict ▁if ▁the ▁ad hes ive ▁will ▁make ▁good ▁contact ▁with ▁the ▁memb rane . ▁ ▁Cons olid ation ▁stage ▁ ▁Str ong ▁and ▁prolong ed ▁ad hes ion ▁▁ ▁The ▁cons olid ation ▁stage ▁of ▁mu co ad hes ion ▁involves ▁the ▁establishment ▁of ▁ad hes ive ▁interactions ▁to ▁rein force ▁strong ▁or ▁prolong ed ▁ad hes ion . ▁When ▁mo ist ure ▁is ▁present , ▁mu co ad hes ive ▁materials ▁become ▁activ ated ▁and ▁the ▁system ▁becomes ▁pl astic ized . ▁This ▁stim ulus ▁allows ▁the ▁mu co ad hes ive ▁mole cules ▁to ▁separate ▁and ▁break ▁free ▁while ▁proceed ing ▁to ▁link ▁up ▁by ▁weak ▁van ▁der ▁Wa als ▁and ▁hydro gen ▁b onds . ▁Cons olid ation ▁factors ▁are ▁essential ▁for ▁the ▁surface ▁when ▁exposed ▁to ▁significant ▁dis l od ging ▁str esses . ▁Multiple ▁mu co ad hes ion ▁theories ▁exist ▁that ▁explain ▁the ▁cons olid ation ▁stage , ▁the ▁main ▁two ▁which ▁focus ▁on ▁mac rom ole cular ▁inter pen etr ation ▁and ▁de h yd r ation . ▁ ▁Mac rom ole cular ▁inter pen etr ation ▁theory ▁▁ ▁The ▁Mac rom ole cular ▁Inter pen etr ation ▁theory , ▁also ▁known ▁as ▁the ▁diffusion ▁theory , ▁states ▁that ▁the ▁mu co ad hes ive ▁mole cules ▁and ▁m uc us ▁g
