Masterbatch people will know the 11 points commonly used questions

What is the difference between granulation and color masterbatch?

Color Masterbatch coloring and granulation compared to color has the following advantages:

1, coloring and processing of finished products to complete, to avoid granulation coloring of the plastic heating process, to protect the quality of plastic products is good.
2, so that the most simple production process of plastic products.
3, can save a lot of power.

Will the product coloring with the masterbatch fade?

There is no fade products, the use of color masterbatch products are still possible to fade, but for different grades of different products only, some more obvious, and some are difficult to detect.

How do I use a masterbatch?

The use of color masterbatch is very simple, just according to the provisions of the ratio of resin particles mixed with the manual mix can be. In the operation of the equipment should pay attention to the following questions:

1, injection molding machine or extruder mixing chamber generally have a number of temperature areas, which close to the blanking mouth that part of the temperature should be slightly higher, which is to make the masterbatch into the mixing chamber after the rapid melting, with plastic resin as soon as possible Mixed evenly, which is conducive to color masterbatch in the products in a good dispersion.

2, the appropriate application of the injection molding machine back pressure, which can improve the mixing effect of the screw, favorable dispersion of the pigment, the side effect of the back pressure is to make the injection rate has slowed down.

3, the extruder die temperature appropriate to improve, can increase the brightness of products.
 

How to determine the use of color masterbatch?

Determine the basis of the use of color masterbatch is to obtain a satisfactory coloring effect. As long as the product surface color tone, no stripes and spots, you can recognize.
The use of color masterbatch can be selected as follows:
1: 100 unless the equipment is very good mixing, or prone to uneven pigment dispersion phenomenon, generally do not recommend customers to use this ratio. However, some customers due to price pressure, especially want to use this proportion of the masterbatch, for the sake of customers, masterbatch manufacturers are also more production of such a low proportion of concentrated masterbatch, and the dispersion of the pigment can generally meet the requirements.
1:50 for coloring requirements of the general plastic products, PE, PP masterbatch more use of this ratio.
1: 33-1: 25 for coloring requirements of higher PO products, coloring requirements of lower or general ABS products.
1:20 for advanced plastic products, including PO, ABS, can be widely used in injection molding, blow molding, spinning and other processes.
1:20 or more generally used for high-level cosmetic container coloring, more for small injection molding machine.

How to calculate the use of color masterbatch?

Calculate the cost of color masterbatch should be deducted the weight of the masterbatch itself, for example as follows: 100 kg plastic resin by adding 2 kg color masterbatch, this time the total weight has been 102 kg, assuming the resin price of 10 yuan / kg, For 20 yuan / kg, the 102 kg plastic products due to the use of Color Master and increase the cost: 2 kg × (20 yuan / kg -10 yuan / kg) = 20 yuan converted into 100 kg of plastic products due to the use of color Mother and increase the cost: 20 yuan / 102 kg × 100 kg = 19.61 yuan.

Will the use of a masterbatch increase the cost of the product?

In most cases this is the case. But in some cases, the use of color masterbatch color than the use of coloring color economy, because the color division can be a combination of several lower prices to achieve a higher price pigment pigment coloring effect. Also consider the following two phenomena:
1, in many cases, the plastic products manufacturers in the use of color when the pigment is not the most economical, and because the pigment is not familiar with, color repeated trial, resulting in human and material waste is very common. The use of color masterbatch does not exist this problem.
2, with color masterbatch products and coloring products with the color of its grade is completely different, and its price should be higher, higher than the price is often higher than the cost of using the color masterbatch, so the color But the mother can create a "profit." From this perspective, in some cases, the use of color masterbatch coloring than the use of toner to be "economic".

Does the masterbatch need to be dried before use?

Color Masterbatch generally do not need to be dried, can be used directly, but, except ABS and NY Colors, they should be dried according to conventional processes.

How long is the shelf life of the masterbatch?

Color Masterbatch can be stored for long periods of time. Colorants in the color of the pigment dispersed in the carrier resin, in a closed state, even if the quality of long-term storage will not change. But should be stored in a dry, cool environment.

Is it possible to formulate colors with several different colorants?

The general company often use several masterbatch for the small amount of customers to prepare a specific color, but without the guidance of the company's technical staff, the customer can not be self-assertion of several masterbatch with the use of different companies can not be mixed with the use of color masterbatch , So as to avoid incompatibility and cause losses.

Is it possible to use other products that affect the performance of the product?

Some pigments have an effect on the flame retardant effect of the product. Used in flame retardant products, should be made to the masterbatch manufacturers.

Does the mold have any effect on the use of the masterbatch?

In order to fully show the coloring effect of the masterbatch, the mold must have the appropriate quality, especially the surface must be very smooth.
