    摘要: An irreversible temperature indicating paint comprises 25 wt % to 50 wt % cobalt silicate, 0 wt % to 20 wt % alumino silicate, 0.5 wt % to 5 wt % toluidine red, 25 wt % to 40 wt % acrylic resin and 10 wt % to 20 wt % silicone resin excluding solvent. The solvent comprises a mixture of 80% 1-methoxy-2-propanol and 20% dipropylene glycol monomethyl ether. The irreversible temperature indicating paint has at least five colour changes in the temperature range 1050° C. to 1350° C. A particular irreversible temperature indicating paint comprises 33.8 wt % cobalt silicate, 16.9 wt % alumino silicate, 2 wt % toluidine red, 30.8 wt % acrylic resin and 16.5 wt % silicone resin excluding solvent. The irreversible temperature indicating paint is used to determine the temperatures to which various parts of turbine blades, turbine vanes or other components are subjected in operation of the gas turbine engine.
