This measured kinematic viscosity is generally expressed in seconds of flow time which can be converted into centistokes using a viscosity disc calculator.
Viscosity measurement flow cup.
Excess fluid is collected in the gutter channel.
Whether your spraying wood finishes industrial enamels or anything in between a paint viscosity cup allows you to know just how thin your paint is.
However the conditions in a simple flow.
Mxbaoheng nk 2 viscosity cup 50ml viscometer flow cup mixing thinning tool 70 370cst for paint industry viscosity measurement 3 0 out of 5 stars 1 31 56 31.
Viscosity flow cups are very easy to use instruments of anodized aluminum with a stainless steel orifice for measuring the consistency of paints varnishes and similar products.
For example syrup has a higher viscosity than water.
A flow cup is a cup of a specified size and volume with an overflow channel at the top and a hole of a defined size in the bottom.
The process of flow through an orifice can often be used as a relative measurement and classification of viscosity.
Different cups have different shapes and hole sizes and because times too short or too long are unsuitable for any given viscosity there is an optimum cup with times.
The unit of measurement is centipoise a universally used metric unit of viscosity.
The viscosity of a fluid is a measure of its resistance to deformation at a given rate.
For liquids it corresponds to the informal concept of thickness.
And they are available in a range of designs in accordance with national and international standards with various orifice diameters to suit different viscosities.
The measured kinematic viscosity is generally expressed in seconds s flow time.
Viscosity cups consist of a hollow cylinder which terminate in a nozzle in the bottom.
Under ideal conditions this rate of flow would be proportional to the kinematic viscosity expressed in stokes and centistokes that is dependent upon the specific gravity of the draining liquid.
Efflux cups flow cups based on different design types zahn shell gardco ez zahn gardco signature zahn and din the unit of measurement is seconds or the time it takes to drain the test cup all cups hold a standard amount of fluid.
The ford viscosity cup is a simple gravity device that permits the timed flow of a known volume of liquid passing through an orifice located at the bottom.
Many printers coaters measure their viscosity using cups with holes in the bottom by finding how many seconds it takes to empty the full cup or rather for the flow to break.
Additionally knowing the viscosity of your paint allows you to have a reference range so you can select equipment settings that will let you achieve a.
