Description
Technical Field
The utility model belongs to the technical field of the coating technique and specifically relates to a measure instrument of coating viscosity, the viscosity of high viscosity coating such as specially adapted polyurethane putty is measured.
Background
A stormer viscometer is a test instrument mainly used for measuring the viscosity of paint and other coatings, under the condition that the temperature of a sample is 25 ℃, a stirring blade (also called a rotor) is driven by a constant-speed motor to rotate at the speed of 200r/min, and the resisting moment of the stirring blade rotating in the tested sample is converted by a computer into a KU value (a logarithmic function of load required by Krebs (Krebs) unit (KU) to generate the rotating speed of 200r/min is generally used for representing the viscosity for brushing and rolling). The KU value or the load value related to the KU value of the sample can be directly read from the instrument by an operator only by putting the stirring blade into the tested sample to a specified depth, and the KU value or the load value is widely applied due to the convenience of use.
However, when the current stormer viscometer is used for viscosity test of high-viscosity coatings such as polyurethane putty, the following problems are caused, and the result is inaccurate:
(1) in the prior art, the sample cup filled with the coating sample to be measured is simply placed on the object placing table, and for polyurethane putty with high viscosity, the stirring paddle blade frequently drives the sample cup to shake in the stirring process, so that the measurement result is inaccurate, and the sample cup can be overturned even under severe conditions. Although some sample cups are fixed by using a locking device composed of symmetrically arranged bolts (for example, chinese patent CN207197987U), the operation is very complicated.
(2) The temperature of the coating sample at the time of the test is not 25 ℃ as specified by the relevant standard.

The infrared temperature sensor adopts a non-contact mode during temperature measurement, so that the coating is prevented from polluting the sensor, and the trouble of repeated scrubbing is reduced. The elevator mechanism 23 is connected between the rod 22 and the housing 31, and may be connected as in the prior art, as shown in fig. 1.
In this embodiment, a cooling loop and a heating loop are connected in parallel between the heat exchange medium inlet 41 and the heat exchange medium outlet 42, a cold water tank and a cooling water pump are arranged on the cooling loop, a hot water tank and a heating water pump are arranged on the heating loop, and the infrared temperature sensor, the cooling water pump and the heating water pump are all connected with the control module.
