TECHNICAL FIELD

[0001] The utility model relates to the field of solidification photosensitive material production, in particular to a kind of rotary viscometer for UV solidification photosensitive material detection. BACKGROUND

[0002] UV solidification photosensitive material will cause polymerization under the irradiation of certain wavelength UV light, change from liquid to solid.Viscosity and fluidity of UV solidification photosensitive material will affect its adhesion, affect whether UV solidification photosensitive material can fully penetrate the surface of the material to be bonded. Therefore, viscosity detection needs to be carried out on UV solidification photosensitive material after production. Rotary viscometer is composed of viscometer body with rotor and measuring cup. During testing, the liquid to be detected is located inside the measuring cup, and the rotor is immersed in the liquid to be detected. The rotor rotates in the measuring cup at a certain speed, thereby driving the liquid in the cup to rotate. When the rotor rotates, it will be subject to viscous resistance of the liquid, and this resistance will cause the rotational speed of the rotor to drop. By measuring the rotational speed of the rotor, the viscosity of the liquid can be calculated. When the viscometer rotor is put into the sample, air bubbles should be avoided, otherwise the measured viscosity value will be reduced, and the rotor cannot touch the bottom and wall of the cup during detection.
