An Outflow Cup Viscometer

Abstract

The invention relates to an outflow cup viscometer, which includes a height-adjustable funnel support, a base, a temperature controller, a pipette and an inner tube, and the vertical rod of the funnel support is arranged on the base, and the base is arranged to place Groove; a temperature control device is set on the horizontal bar of the funnel support; the inner tube is fixed inside the pipette; the inner tube includes a tube part and a funnel cone arranged below the tube part, and the funnel cone part and the tube part An anti-slip groove is provided on the outer wall of the contact position; an anti-slip ring is provided between the inner tube and the pipette; the section of the anti-slip ring is shaped, including an anti-slip part and an inlay part; the inlay part is hidden on the inner wall of the pipette, so The inlay part is stuck in the anti-slip groove. The invention has a novel design, and since the heater and the temperature measuring device are provided, it can ensure that the temperature of the tested fireproof coating is consistent during measurement, and reduce the influence of temperature on the viscosity during measurement. The bracket can ensure the stability of the measuring cup and avoid measurement errors caused by shaking.

Description

technical field [0001] The invention relates to an outflow cup viscometer. Background technique [0002] Among the many instruments for detecting viscosity, the most economical, practical and convenient to operate is the outflow viscometer-outflow cup. The design principle of the outflow cup is to restructure and enlarge it on the basis of capillary tubes. There are many models in various countries, such as the Ford cup in the United States, the DIN cup in Germany, the BS cup in the United Kingdom, the Tu 21 cup and Tu 24 cup in my country, etc. The outflow cup viscometer uses the gravity of the sample itself to generate flow, and it is usually expressed by the time for a certain amount of sample to flow out of the viscosity cup at a certain temperature, in seconds.

AI Technical Summary

Problems solved by technology

When measuring, temperature is an important factor affecting the viscosity of the sample, so the viscosity measurement must be carried out in a constant temperature room, but when the existing viscometer measures, it cannot guarantee a constant temperature environment during the measurement process, resulting in an increase in the error of the measurement result

In addition, all coating viscometers do not have a fixing device for the bucket or cup during the measurement; thus, in the actual measurement, the work difficulty of the tester is increased, the operation is inconvenient, and the test efficiency is reduced
