| titleOfInvention | Sintering-free inorganic film and preparation method and application thereof |
| abstract | The invention provides a sintering-free inorganic film and a preparation method and application thereof, wherein the preparation method of the sintering-free inorganic film comprises the following steps: providing a porous support body; carrying out sand blasting treatment on the surface of the support body by a sand blasting machine to achieve certain roughness; cleaning the surface of the porous support body by using industrial sodium water glass or industrial potassium water glass; preparing geopolymer slurry; and coating the geopolymer slurry on the surface of the cleaned porous support to form a geopolymer coating, and curing to obtain the sintering-free inorganic membrane. According to the invention, the combination between the porous support body after the water glass cleaning treatment and the geopolymer coating is better, and the prepared inorganic membrane is not easy to crack. The sintering-free inorganic membrane prepared by the invention has the pore size distribution of 2-100 nm, and can be used for filtering drinking water and sewage; experiments show that the inorganic membrane prepared by the method can reduce the turbidity of sewage and can remove suspended matters, heavy metal ions and coliform bacteria in the wastewater. |
