The volatility of the solvent in the paint viscometer determines the color of the ink
At present, in the printing industry, the viscosity adjustment and control of the ink are mostly controlled by manual dilution and monitoring. Due to the volatility of the solvent, the color of the ink will change with time. It is very difficult to monitor the viscosity of the ink only by manual methods. It is difficult to keep the color of the ink consistent from beginning to end, especially when printing products, which affects the quality of the product. This instrument is based on this idea. As long as the colorist adjusts the color and viscosity of the ink according to the quality requirements of the product, It can automatically monitor ink viscosity and control accuracy
The paint viscometer is suitable for measuring the viscosity of paint products with a viscosity of less than 150 seconds. The paint viscometer is manufactured according to the requirements of the national standard "GB/T1723 Paint Viscosity Measurement Method". It is a portable instrument for conditional measurement of paint viscosity, namely The viscosity of the liquid is calibrated by the time required for the measured liquid to flow out of the standard tube hole after it is filled with a specific container. in seconds
The viscosity of the paint is also called the consistency of the paint. The paint viscometer refers to a characteristic that the fluid itself has an adhesive force that hinders its relative flow inside the fluid. This indicator mainly controls the consistency of the paint, which meets the requirements of use, and directly affects the construction performance, leveling and sagging of the paint film. By measuring the viscosity, you can observe the degree of polymerization of the paint after storage for a period of time, and adjust the viscosity with a suitable diluent according to different construction requirements, so as to achieve different viscosity indicators required for brushing, air spraying, and airless spraying.
Viscosity is an important index reflecting the physical properties of the fluid, and its size directly reflects the frictional resistance between the various flow layers when the fluid flows.
According to Newton's law of viscosity, viscosity can be defined by the following formula:
η viscosity = ShearStress shear stress / ShearRate shear rate.
