| 21-يناير-25 | US18/436,895 | US12204279B1 | Toner and method of formation using fly ash-rich carbon | A toner based on fly-ash rich carbon and method of producing are disclosed. The process includes preparing a latex and preparing a pigment including fly ash, where the fly ash has been ground to nanoparticle size. The latex, pigment including fly ash, and polyethylene wax are combined in an emulsion aggregation process. The latex is formed by a mixing process including combining ammonium bicarbonate, sodium dodecylbenzene sulfonate, styrene, acrylic acid, and methyl methacrylate. The emulsion aggregation process includes steps of dispersing a mixture of the polyethylene wax, pigment including fly ash, and latex in water, adding zinc oxide, nitric acid, adding Ethylenediaminetetraacetic acid (EDTA), elevating the temperature, neutralizing the product mixture with NaOH solution and cooling the mixture, Centrifuging, washing and drying are performed to achieve a finished toner which includes fly ash pigment, polyethylene wax, poly(styrene-methyl methacrylate-acrylic acid) latex, zinc oxide and a chelating agent. | Seham Soliman AlteraryAthar Mohamed Elhadi | Chemistry/Nanoparticles | G03G9/0817 |
