Stability should be common.
In today's international economy, international customers on the quality of masterbatch, raw material stability and other high demand is certainly necessary, color masterbatch which is the resolution of the black masterbatch quality of the fifth element. One of the primary manifestations of stability is the steady carbon black share.
Second, the brightness to be clear.
Resolve the black masterbatch quality at the end of an element is the color of the brightness. There are various types of carbon black can be used for masterbatch color, but all kinds of colors and quotes are also very different. The large particles of carbon black have a lower chroma and a different background than the small particles of carbon black.
3. The classification and use of carbon black usually.
SRF carbon black is usually used for those who do not need strong color strength, high cover or UV maintenance of garbage bags produced. The color tends to be gray and blue, offer cheap, and relatively easy to disperse, color masterbatch so those who are equipped with single or double screw extruder master grain manufacturers will choose this carbon black. HAF carbon black particle size is SRF carbon black particles in half, but the color strength is 2 times.
Fourth, the activity is better.
The third element of the resolution of the black masterbatch quality is rheology and activity. If a masterbatch itself has outstanding dispersion, but it can not move into the mold to be molded, then the role of production is not aspiring. color masterbatch In general, the backing resin used to produce the masterbatch has a high rheology. In order to save capital, some masterbatch producers use the repeated use of information, waste or renewable materials as a resin carrier.
V. Compatibility is big.
Compatibility of the resolution of the black masterbatch quality of the fourth element. If the masterbatch is produced from chips or recycled materials, it can be rich in contaminants or other non-melted polymers. This will lead to some unexpected, difficult to bind the trouble, a waste of the end of the consumer's time and material. At this time, can use the backing resin to produce high-quality masterbatch, masterbatch in the melting process have outstanding compatibility.
Six times the dispersion is high.
Black masterbatch is produced using carbon black. Raw carbon black is very difficult to deal with and dirty mix, it is full of dust, light weight, color masterbatch was loose. Unless the use of large-scale disposal methods, or it will dirty machines and workers, so that the working environment becomes dirty. Because of this, casting workers all over the selection of a resin carrier, that is, black masterbatch, the end of carbon black pre-dispersion.
Seven. Cover the power to be strong.
The second element of the resolution of the quality of the black masterbatch is the cover force, which is particularly important for the masterbatch used for waste or recycled polymers. In these cases, the black effect is to conceal the Other colors. color masterbatch Large particles of carbon black color can be poor, not easy to cover all the other at the grassroots level, the results of the end of the product only get away from the color.
