The following is the test of the BaSO4 Filler Masterbatch color
Usually BaSO4 Filler Masterbatch technology wet process. Color of the particles of water and water phase mother grinding, phase, cleaning, dry, granular, the quality assurance of this product can be. In addition, a series of inspections of BaSO4 Filler Masterbatch technology, such as measuring the thickness of the sand slurry, measuring the performance of the abrasive slurry dispersion, measuring the solid and color paste of the sand slurry, and the like.
BaSO4 Filler Masterbatch generally consists of three parts, no color occupational dispersant, after mixing through high-speed mixing machine, cracking, promotion granulation, BaSO4 Filler Masterbatch plastic processing process, is a high concentration, good dispersion, cleaning and other significant advantage.
Plastic color, that is, high content of pigment (or dye homogeneous) to pay the plastic resin in the granular toner. BaSO4 Filler Masterbatch is added to a wide range of colors such as Dilution Resins or Extrusion Technologies for wire and cable, food and cosmetic packaging, automotive and home appliance parts, etc., logo, landscaping and replacement As a manufacturer of professional BaSO4 Filler Masterbatch, it is not only the color required by the guests, but also to ensure that the color of each product is reproduced in the same way, if the color control is within a certain range of tolerance. This is an extremely important quality control indicator for the manufacturer.
The following is the test of the BaSO4 Filler Masterbatch color, the cause of the improvement and the improvement of the measures, (CIELAB), after mixing, the extruded particles are taken in the same way, after the resin and mixed dilution, the injection molding machine and the double- Sample. If the sample and the standard sample between the test results of the color difference, the product within the specified range of color, the product that is qualified products, or adjust the masterbatch formula.
The usual BaSO4 Filler Masterbatch color difference test is combined with a computer with a spectrophotometer. Apparatus with the naked eye sensitivity is only a different generator deviation, the combination of the two must be tested. Sometimes the machine test qualified unqualified visual inspection, is in. I have visualized a few quantifications that do not limit the amount of effective display of the device. Part of the color only, measuring equipment visual. In general, the color of the various colors, the test method shows.
Different grades of resin its density and melt index will be different, so the performance of the resin will be different, and BaSO4 Filler Masterbatch compatibility will be different, resulting in color changes, in general, as long as its density and melt index difference Not big, then the color difference will not be too much, you can adjust the amount of color master to correct the color.
Some BaSO4 Filler Masterbatch pigment content is very high, in this case, the migration phenomenon is normal. In particular, the addition of dye color masterbatch, will occur serious migration phenomenon. But this does not affect the quality of the product, because BaSO4 Filler Masterbatch injection into the product, the pigment in the product in the normal color concentration.
The first is the rinse method, that is, by the paint, dispersant and water through the sanding, so that our pigment particles are less than a micron, and then through the phase transfer method makes this pigment into this Fuel tank, and then make the case in the dry BaSO4 Filler Masterbatch, in the box when we need to use some organic solvents and the corresponding solvent to do the recovery device;
The second point is the ink method: As the name suggests, is in our BaSO4 Filler Masterbatch in the production of ink paste when the production method, that is, can be three roller grinding, in the surface of the pigment layer covered with a low The protective layer of the molecule, so that after the grinding of the fine paste and then the carrier of the resin to do the mix, and then go through the bachelor of the mill, the plastic, and finally go through this single screw or Is the twin-screw extruder on the granulation。
