Masterbatch production process and advantages

Masterbatch production process:

Masterbatch is a must-use colorant in plastic products, and the principle of masterbatch granulator is to change the application of masterbatch in plastic products through the complex structure inside the plastic, so that the gravitational interaction between molecules Become a tough plastic. The masterbatch granulator screw adopts the principle of building blocks, and its length-diameter ratio, barrel structure, screw arrangement, network replacement structure, exhaust quantity and position, feeding method, electrical control can be required according to the processing material system and process admiration requirements. Methods, etc., can be optimized rational configuration.

The masterbatch granulator production process can be divided into 7 steps:

1. Weighing: Toners, carriers, lubricants, dispersants and other additives are weighed according to the requirements of the process, and the higher the precision, the better.

2. Stirring: The auxiliaries are put into the high-mixer in order according to the process flow.

3. Extruder: According to the carrier temperature of the masterbatch, it can be turned on after a certain period of time, and the speed can be increased from slow to fast.

4. Pull the bar: After the die discharge, hold the bar evenly and move it to the pelletizer at a uniform speed, passing through the blow dryer or the suction dryer.

5. Chela: Slowly increase the speed of the pelletizer when the strand reaches the feed inlet of the pelletizer.

6. Packaging: Packaging according to customer needs.

7. Subsequent adjustments: The full set of equipment is operating normally for a period of time, and the speed is adjusted to the normal production speed.

Masterbatch advantages:

1. Make pigments have better dispersibility in the product.

In the production process of masterbatch, the pigment must be refined to improve the dispersibility and coloring power of the pigment. The carrier of the special color masterbatch is the same as the plastic type of the product and has a good match. The pigment particles can be well dispersed in the plastic of the product after heating and melting.

2. It helps to maintain the chemical stability of the pigment. When the pigment is used directly, the pigment will absorb water and oxidize due to the direct contact of the pigment with air during storage and use. After the color masterbatch is formed, the resin carrier will mix the pigment and air. Moisture isolation, can make the quality of pigments long-term unchanged.

3. Ensure the stability of the color of the product.

The masterbatch particles are similar to the resin particles, and are more convenient and accurate in metering. When the mixture is mixed, it does not adhere to the container, and the mixture with the resin is also uniform. Therefore, the amount of the additive can be stabilized, thereby ensuring the stability of the color of the product.

4. Protect the health of operators.

Pigments are generally powdery, easy to fly when added and mixed, and will affect the operator's health when inhaled by the body.

5. Keep the environment clean.

6. Easy to use.
