| 英文摘要 | Potassium silicate coating foams seriously at high temperature. SiO 2 , TiO 2 and Ti particles were added to solve this problem. Micro -morphologies, phase composition, mass change kinetics were analyzed, porosity and volatilizable water contents ( x0 ) of coatings were calculated to reveal the effects of adding SiO 2 , TiO 2 , and Ti particles on the foaming behavior of potassium silicate coatings at 500 degrees C. The higher the x0 , the more severe the foaming becomes. Results shows that addition of fillers improved the anti -foaming resistance due to volume occupier effect. Among them, SiO 2 particles did not alter x0 of the as -prepared coatings due to similar tetrahedral structure with silica, addition of TiO 2 particles increased x0 because titania can form more -Ti-OH groups than silica, Ti particles decrease x0 because dissolved Ti 4+ ions can decrease the number of the pending -Si-OH bonds. Combined with the volume expansion occurred due to the oxidation of Ti particles during heat treatment, potassium silicate coating modified by 30 wt% Ti exhibited the best anti -foaming performance with the lowest porosity, at 1.8%. |
