Abstract

Úprava geopolymerního materiálu pro zvýšení smáčivosti vodou spočívá v tom, že povrch geopolymerního kompozitu se podrobí působení nízkoteplotního plazmatu po dobu alespoň jedné vteřiny a toto působení nízkoteplotního plazmatu na geopolymerní kompozit po dobu alespoň jedné vteřiny se jednou či vícekrát zopakuje, přičemž se použije atmosférické plazma o teplotě nejvýše do 80 °C. Aplikací atmosférického plazmatu se dosáhne modifikace povrchové vrstvy geopolymerního kompozitu nanášením reaktivních a hydrofilních hydroxylových částic a povrch geopolymerního kompozitu se současně nitriduje.The modification of the geopolymer material to increase water wettability consists in subjecting the surface of the geopolymer composite to the action of a low-temperature plasma for at least one second, and this action of the low-temperature plasma to the geopolymer composite for at least one second is repeated one or more times, using an atmospheric plasma of temperature up to 80 °C. By applying atmospheric plasma, modification of the surface layer of the geopolymer composite is achieved by applying reactive and hydrophilic hydroxyl particles, and the surface of the geopolymer composite is simultaneously nitrided.
