Resin as an important part of water-based plastic gravure ink which directly affect the performance of ink.
Glossiness is an important index of printing quality. resin determines the surface properties of ink film, so it has a significant influence on ink glossiness.
Therefore, to obtain high gloss ink should use the resin with small particle size, well dispersion properties.

In this paper, the operating principle and properties of MFDMs are briefly presented based on our previous work [5-7].
When subjected to a magnetic field, the suspended particles affect the flow properties of the carrier fluid.
The varying magnetic field in turn affects the equipotential surface thus providing means to control the shape of the magnetic fluid surface.
The susceptibility of the magnetic fluid volume to mechanical vibrations is one of the most obvious concerns associated with use of MFDMs.
For applications that require the AO setup to be positioned on a moving platform, the mechanical vibrations as well the strict requirement of keeping the MFDM surface horizontal remain the prohibiting factors.

It was found that the holed-inserts contributed both positive and negative affects to the tool life extension under JC method at Vc = 100m/min, ap = 0.3mm and f = 0.1mm/rev.
However, it should be noted that the effect of coolant disturbance caused by the contraction is not a decisively negative factor, but rather necessary to be evaluated with other factors such as substrate material and cutting parameters.

Each offset scenario is analyzed independently to isolate the effects of spatial displacement on stress intensity factors and local stress fields.
Material Selection and Their Properties Three different material definitions are employed to accurately represent the components of the assembly: · The cylindrical shell is modeled using SA-516 Grade 70 carbon steel, a material widely used in pressure vessel construction.
The weld region between the nozzle and shell is assumed to share the same material properties as the nozzle to simplify the interface modeling and maintain numerical consistency
