Ink viscosity cup


TOYO ink viscosity cup, RIGO ink viscosity cup.
Ink viscosity cup also known as observing grace cup, mainly used in printing ink, coating agent, adhesive and so on viscosity determination, test results are correct, easy to use.
Principle: the measured liquid Sheng into the viscosity cup cup body, determination of liquid flowing from the lower part of the cup body hole of the time (in seconds) to measure the viscosity of the liquid.
General specifications are: 2, 3, 4... 7, commonly used models: 3, 4
Characteristic
1, the use of the ink viscosity cup can accurately measure the viscosity of ink.
2, ink viscosity cup service life is 3 times the domestic.
3, small size, easy to operate.
Use:
Widely used in gravure, letterpress, flat plate, flexographic printing, silk edition printing ink industry application before or use among viscosity measurements.
Matters needing attention:
Gravure printing ink drying is completed by solvent evaporation, heat and wind through the role of ink drying. Ink drying rate and the printing speed and drying device matched with its based regulation, when the drying too slow, in ink add quick drying solvents or dry weights and release agent, drying too quickly in the printing ink joined the slow solvent or slow thousands of diluent. Ink viscosity of the master in order to ensure the ink in the storage process does not precipitate, viscosity generally are larger, when printing using should appropriate dilution, in order to achieve the required viscosity and liquidity, depending on the structure of the machine and the printing speed, generally with the No. 4 viscosity measuring cup ink sticky degree, the machine to print speed in 20-80m / mm between the. Viscosity between 22-28 seconds. The viscosity of the ink, when with a dilute agent, should stir the methodof release agent is uniformly distributed in trimming ink. Because the indoor temperature and humidity affecting the concentration of ink, the best use of ink concentration detector to determine the solvent is added to the amount of, according to the change of temperature and humidity, at regular intervals test concentration of ink.
The company's distribution of the viscosity cup Japan clutch, TOYO, Japan, etc.
