| titleOfInvention | A kind of high temperature and high pressure acid and alkali resistant enamel and preparation method thereof |
| abstract | The invention discloses a high temperature and high pressure acid and alkali resistant enamel and a preparation method thereof. The formulation of the enamel is: SiO 2 : 69-77%; Na 2 O: 8-12%; ZrO 2 : 6-8%; Li 2 O: 2-4%; K 2 O: 1-3%; Al 2 O 3 : 1.8-3%; CaO: 1-3%; CoO: 0.5-0.7%; Fe 2 O 3 : 0.3-0.5% . The enamel has excellent performance, the corrosion resistance of 20% boiling hydrochloric acid for 48h can reach 0.25～0.35g/m 2 ·d, and the corrosion resistance of 0.1mol/L 80℃ sodium hydroxide for 24h can reach 0.9～1.2g/m 2 ·d. The mechanical impact resistance performance index of the glass layer can reach 290×10 3 ～340×10 3 J, and the temperature difference resistance performance index can reach 260～270℃. The invention can maintain good acid and alkali resistance under high temperature and high pressure conditions. |
