Black Masterbatch is composed of carbon black, the carrier and additives such as injection molding processes link the production of masterbatch materials. In recent years, it has a very important role in many industries. Black gives a mysterious, high-end color perception, thus black masterbatch can add a cutting-edge fashion label with its products. But in some cases, for some reasons that cause black masterbatch can not be well dispersed, resulting in uneven dispersion effect, thus affecting the appearance of the article. Today, Ozawa would mainly tell you about, unequal treatment of black masterbatch dispersed in several ways, for your reference Oh!

Method One:

The dried material to do, if with wet material, it first will spout melted, but not completely melted, it will be crowded in there does not go into the dried material more easily than wet material.

Method two:

The spout temperature is reduced, or even drop very low, such as 100 degrees, so. Feed not only into the first melt, but directly pushed into, by the power of the screw, rather than heat. This downside is expected for a long time to do so, to screw damage is relatively large.

Method three:

Pick up with a broken screw do, put in front of that cut diameter, slightly later than the exchange of small dots. The gap is large, but also easy to feed.

Four:

The feed inlet increase, if you are expected to do so long, you can cut the feed inlet bigger. Of course, the light does not mean that you can cut a large multi-feed mixing equipment can be installed, refer to the end of PS foam material production equipment.

Five:

Change the motor plate. The rotating disc diameter for large, so the screw speed is fast, disguised in the dissolved material not put it stir inside. Downside is accidentally broken screw stir. After faster heating zone to be in the back of the temperature increase, otherwise the screw too much force to bear.

RAJ Tip: use black masterbatch have different proportions in different products. You do not use the wrong Oh!

1: 100: Unless mixing equipment is very good, or prone to the phenomenon of uneven pigment dispersion is generally not recommended to use this scale.

However, some customers because of the price pressure, especially wish to use the percentage of masterbatch, for the customer, but also more to produce such a low proportion of concentrated masterbatch, and pigment dispersion in general can meet the requirements.

1:50: general requirements for the coloring of plastics, PE, PP masterbatch more use of this ratio.

1: 33--1: 25: requirements for high tinting PO class products, coloring or less demanding general ABS products.

1:20: For high-grade plastic products, including PO, ABS, can be used in injection molding, blow molding, spinning and other processes. Above 1:20 is generally used for high-quality cosmetics containers coloring, more land for small injection molding machine.
