Umgubo we-latex we-polymer ophinda unyibilikeIimveliso ziipowder ezinyibilikayo emanzini, ezahlulwe zibe zii-ethylene/vinyl acetate copolymers, ii-vinyl acetate/tertiary ethylene carbonate copolymers, ii-acrylic acid copolymers, njl.njl., kunye ne-polyvinyl alcohol njenge-colloid ekhuselayo. Ngenxa yomthamo ophezulu wokubopha kunye neempawu ezizodwa zeepowders zepolymer ezisasazekayo.
Ukongeza umgubo wepolymer osasazekayo kwi-mortar egcwalisa amalungu kunokuphucula ukuhambelana kwayo kunye nokuguquguquka kwayo.
I-bonding mortar kufuneka inamathele kakuhle kwizinto ezisisiseko ukuze ibotshelelwe nokuba isetyenziswa kancinci kakhulu. Ii-samente mortars ezingatshintshwanga ngokubanzi azibotshelelwa kakuhle ngaphandle kokulungiswa kwangaphambili kwesiseko.
Ukongezwa kwepowder yelatex ephinda inyibilike kunokuphucula ukunamathela. Ukumelana kwesaponification kwepowder yelatex ephinda inyibilike kunokulawula inqanaba lokunamathela kwemortar emva kokudibana namanzi kunye neqabaka. Ipolymer enganyangekiyo yesaponification inokufumaneka ngokucopolymerisa i-vinyl acetate kunye nezinye ii-monomers ezifanelekileyo. . Ukusebenzisa i-ethylene njenge-comonomer engenakunyibilika ukwenza iipowder zelatex eziphinda inyibilike ezine-ethylene kunokuhlangabezana nazo zonke iimfuno zeepowder zelatex ngokubhekiselele ekumelaneni nokwaluphala kunye nokumelana ne-hydrolysis.
