Description

Water-based connecting material filtering device

Technical Field

The utility model belongs to the field of binder production equipment, and particularly relates to a water-based binder filtering device.

Background

The aqueous vehicle determines the type of drying, drying speed, ink gloss, abrasion resistance, fastness, etc. of the ink. In aqueous inks, the water-soluble resin and the emulsion polymer mainly function as binders. Viscosity is the most important control indicator in aqueous ink vehicle applications. During the printing process, the low viscosity of the water-based ink can cause the defects of light color, expanded mesh points, uneven ink transmission and the like; on the other hand, if the viscosity of the aqueous ink is too high, the ink transfer performance is relatively poor, and defects such as scumming and plate pasting are likely to occur. In addition, the binder should have good solubility, good dispersibility for the pigment, excellent color developability, and good adhesion to the substrate. In general, the vehicle determines the rheology, viscosity, and printability of the ink. And is therefore critical to the production of the binder.

In the process of producing the water-based binder, the water-based binder needs to be filtered to remove impurities contained in the water-based binder, so that the phenomenon of thread cutting of later-stage printing ink is avoided. The existing water-based connecting material filtering equipment has more problems, such as complex structure, easy blockage of filtering screen by filtered impurities, short use time for removing filter residues and inconvenient slag discharge.

In summary, in order to solve the technical problems in the prior art, the utility model designs the water-based connecting material filtering device which is simple in structure, can automatically remove filter residues on the filtering screen and conveniently and quickly discharges the residues.
