Vertical masterbatch screening plant

Technical Field

The invention relates to the technical field of color master batch screening, in particular to a vertical color master batch screening device.

Background

The color master batch is a special colorant for a novel high polymer material, and is also called a pigment preparation. The color master is mainly used for plastics. The color concentrate is composed of three basic elements of pigment or dye, carrier and additive, and is an aggregate obtained by uniformly supporting an excessive amount of pigment in a resin, and can be called pigment concentrate, so that its coloring power is higher than that of the pigment itself. During processing, a small amount of color master batch is mixed with uncolored resin, and colored resin or products with designed pigment concentration can be obtained.

At present, the color master batch process produced in China is that molecular wax, plastic particles or plastic powder and toner or filler are put into an extruder for extrusion and granulation after being stirred at high speed, the granulation raw materials are mixed and plasticized by the extruder to form plastic melt, plastic strips are extruded by a die head of the extruder, and the plastic strips are cut into plastic particles with certain length by a plastic strip cutting machine after being cooled. In addition pigment is when grinding processing, a series of masterbatch technical detection still should be carried out, like the fineness of survey sanding thick liquid, survey sanding thick liquid's diffusion performance, survey sanding thick liquid's solid content and survey projects such as mill base fineness, now, adopt the screening case to sieve the masterbatch of fashioned size difference mostly, however current screening case area is big, and masterbatch screening effect is poor, lead to the masterbatch finished product of size difference to mix together very easily, work efficiency has been seriously influenced.
