How to solve the uneven dispersion of blown film color masterbatch?

The color master batch is formed by water phase grinding, turning, washing, drying, and granulation, only in this way can the product quality be guaranteed. Uneven dispersion is the most stable and critical reason for the quality of color masterbatch products not being guaranteed. The role of pe wax in blown film production is that it still has good dispersion performance when mixed at high temperatures, thereby improving the uneven dispersion of color masterbatch.

The problem and solution of uneven dispersion of blown film masterbatch:
The appearance of color spots on the surface of blown film products is due to uneven dispersion of the color masterbatch and poor plasticization of the raw materials. The manufacturer of Qingdao Sainuo polyethylene wax suggests replacing the filter screen to improve the fineness of the mesh, increasing the temperature of the material barrel, and adding dispersants to improve dispersion. The common method is to add polyethylene wax (PE wax) to improve the dispersion performance of the color masterbatch and improve flowability.

Advantages of polyethylene wax in color masterbatch blown film production:
1. Improve dispersion
2. Increased shear force
3. Improved pigment wetting and dispersion performance
4. Has good compatibility and fluidity
Qingdao Sainuo polyethylene wax SN118 has high molecular weight, high viscosity, and balance between lubrication and dispersion. Its dispersion performance is equivalent to BASF A wax and Honeywell AC-6A, and is widely used in industries such as high concentration pigment masterbatch, PVC soft adhesive granulation, and metallurgical injection.

According to different application systems, it is recommended to add color masterbatch at a ratio of 3-5% and PVC0.3-0.5% for this product; Usually, it can be directly added and pre dispersed through high-speed mixing and stirring, with appropriate temperature and time controlled to achieve the best pre dispersion effect;
