Abstract

Przedmiotem zgłoszenia jest sposób wytwarzania nanocząsteczkowego węglanu wapnia charakteryzujący się tym, że: przygotowuje się kąpiel zawierającą wodny roztwór wodorotlenku wapnia (Ca(OH)2); nad powierzchnią kąpieli wielokrotnie wytwarza się z kąpieli film, który kontaktuje się z gazowym dwutlenkiem węgla przez czas niezbędny do absorbcji dwutlenku węgla w filmie, do uzyskania stężenia zapewniającego wytrącenie węglanu wapnia (CaCO3) w filmie, po czym wprowadza się film do kąpieli, przy czym proces wielokrotnego wytwarzania filmu prowadzi się do momentu obniżenia pH kąpieli do zakresu od 7 do 7,5, uzyskując w kąpieli zawiesinę nanocząsteczkowego węglanu wapnia (nanoCaCO3). Przedmiotem zgłoszenia jest także nanocząsteczkowy węglan wapnia uzyskany powyższym sposobem oraz układ do jego wytwarzania.The subject of the application is a method of producing nanoparticle calcium carbonate characterized in that: a bath is prepared containing an aqueous solution of calcium hydroxide (Ca (OH) 2); above the surface of the bath a film is repeatedly made from the bath, which is contacted with carbon dioxide gas for the time necessary to absorb carbon dioxide in the film, to obtain a concentration ensuring precipitation of calcium carbonate (CaCO3) in the film, after which the film is introduced into the bath, the process of repeated film production is carried out until the pH of the bath is lowered to a range of 7 to 7.5, resulting in a suspension of nanoparticle calcium carbonate (nanoCaCO3) in the bath. The subject of the application is also nanoparticle calcium carbonate obtained by the above method and a system for its production.
