Embodiment 1
[0036] A preparation method of irradiation indicating ink, comprising the following steps,
[0037] (1) Mix 0.01% methyl orange, 0.5% chloral hydrate, 17% acrylic resin with water to form an indicator ink and inject it into the stamp, (2) stamp the indicator ink on the surface of the object to be irradiated, (3) absorb 25kGy Imprint changed from orange color to red after dose irradiation.
Embodiment 2
[0039] A preparation method of irradiation indicating ink, comprising the following steps,
[0040] (1) Mix 0.01% methyl orange, 0.5% chloral hydrate, 5% acrylic resin with water to form the indicator ink and inject it into the stamp, (2) stamp the indicator ink on the surface of the object to be irradiated, (3) absorb 25kGy Dose irradiation, due to the instability of the emulsion, causes unevenness in the stamping process, and the color change after irradiation is chromatic aberration.
Embodiment 3
[0042] A preparation method of irradiation indicating ink, comprising the following steps,
[0043] (1) Mix 0.01% methyl orange, 1% chloral hydrate, 20% acrylic resin with water to form the indicator ink and inject it into the stamp, (2) Put the indicator ink on the surface of the object to be irradiated, because the viscosity of the emulsion is too high , resulting in uneven stamping process, (3) 25kGy absorbed dose irradiation, uneven color change after irradiation.
