Origin : Mainland ChinaCup body material : stainless steelNumber of cups : 1, 2, 3, 4, 5Cup size : about 44mlTotal length : about 345mmCup inner diameter : about 33mmCup height : about 57mmProduct Usage:The immersion Caien cup viscosity cup, also known as the Chai's cup, is manufactured according to the relevant regulations of the American Society for Testing and Materials, Standards and Standards for Paint and Raw Materials, ASTM No. D4212-93, Standard Test Method for Immersion Viscosity Cups. This viscosity cup is used to test the viscosity of Newtonian or approximately Newtonian liquids.Caien Cup is widely used in coatings; ink gravure, letterpress, lithographic, flexo, silk and other printing industries; viscosity measurement before or during product application. Mainly to maintain the stability of viscosity during product use, so that viscosity is always maintained In the setting range, to ensure the color value of the product effect.The Cairn Cup is a common tool for measuring the viscosity of liquids.The dynamic viscosity obtained by this common measurement method is often expressed in seconds.It can be converted to centipoise by viscosity conversion (note: kinematic viscosity unit: centipoise).Standard Test Method for Determination of Viscosity in accordance with ASTM D 4212 Impregnated Viscosity Cup.The temperature of the liquid to be tested is 25 degrees Celsius, and it is necessary to ensure that the temperature fluctuation is minimum during the test and cannot exceed +/- 0.2 degrees Celsius.Select the appropriate aperture of the Tyan Cup according to the spec sheet and the expected viscosity range of the liquid to be tested.Immerse the viscosity cup in the test solution and the cup must be completely immersed in the liquid.The temperature of the liquid in the viscosity cup was measured with a thermometer and recorded. Remove the thermometer.Use the indexs finger to lift the ring on the handle so that the viscosity cup is vertical and lift the viscosity cup quickly and stably.Press the stopwatch when the viscosity cup leaves the level. During the outflow, the height of the holding cup should not be higher than 15 cm above the liquid level.When it is observed that the first exact flow of the stream occurs, the timing is stopped.Maintenance:If properly maintained, the Cai En Cup can still be used for many years.To clean the Zahn cup, use a soft cloth and do not use tools such as wire brushes, sandpaper or other abrasive tools.It is especially important to clean the outflow holes to remove residue and to avoid scratching the inside surface.It is recommended to clean the Zahn Cup properly after each use (except for repeated tests)Model and technical parameters:Features: round head stainless steel cup, precision drilling nozzle, exquisite workmanship, accurate measurement, durableModel: Cai En No. 1, No. 2, No. 3, No. 4, No. 5 (No. 8 is a special liquid measuring cup)Measuring range: 5-1840 PCT StokesCalculation: PCT Stokes specific gravity = centipoiseThe specific parameters of the Zahn Cai En Cup are as follows:Model No. 1Measuring range (mm2/s) approx. 5 -- 56Nozzle diameter 2mmApplication very dilute liquidFlow time (s) 35-80Model No. 2Measuring range (mm2/s) approx. 21 ---- 231Nozzle diameter 2.74mmApplication Thinner, mixed paint, varnishRun time (s) 20-80Model No. 3Measuring range (mm2/s) approx. 146 --- 848Nozzle diameter 3.76mmApplication Medium viscosity, mixed coating, varnishRun time (s) 20-80Model No. 4Measuring range (mm2/s) approx. 222----1110Nozzle diameter 4.26mmApply thicker liquids and mixturesRun time (s) 20-80Model No. 5Measuring range (mm2/s) approx. 460--- 1840Nozzle diameter 5.28mmApplication Very thick liquids and mixturesRun time (s) 20-80note:1.
