How to solve the slipper black line during production

The slipper black line in the production may be caused by various factors.

Here are some possible reasons and corresponding solutions:

Material degradation:

Under high temperature and shear force, the material may degrade, leading to the formation of slipper black line. This may be related to insufficient stabilizer content in the formula.

Insufficient lubricant:

During the plasticization process, if the lubricant is insufficient, the friction between the material and the barrel may increase, which may cause the attached substances in the barrel to mix with the material and form slipper black line.

Unreasonable process settings:

Improper setting of parameters such as temperature, pressure, and speed in the production process may also lead to problems with the material during processing, resulting in slipper black line.

Equipment issues:

The temperature of certain parts of the mold or machine is too high, causing the material to burn and form slipper black line.

Improper maintenance of equipment, such as impurities or attachments inside the barrel that have not been cleaned thoroughly, may also affect product quality.

Raw material quality:

The raw materials themselves have quality issues, such as impurities or unstable components, which may also lead to slipper black line in the production process.

How to solve the slipper black line during production?

Silicone masterbatch may indeed help solve the slipper black line problem in production, mainly based on the characteristics and mechanism of action of silicone masterbatch. The following is a detailed analysis of how silicone masterbatch can potentially solve the problem of slipper black line:

Merkmale von Silikon-Masterbatch

Silicone masterbatch, as a lubricant and wear-resistant modifier in plastic processing, typically contains high or ultra-high molecular weight siloxanes that are pre dispersed in polymer carriers such as polyolefins. Silicone masterbatch can blend with almost all types of thermoplastic and significantly improve its processing performance and surface quality of the final product.

Mechanism for solving the slipper black line.

Improve lubricity:

Silicone masterbatch can significantly reduce the friction coefficient between plastic melt and equipment (such as barrels and molds), reducing the heat and wear generated by friction. This helps prevent material degradation during processing due to overheating or excessive wear, which may reduce the formation of slipper black lines.

Improve liquidity:

Silicone masterbatch can improve the fluidity of plastic melt, making it easier for materials to flow and fill molds during processing. This helps to reduce the time spent in the mold due to poor material flow, thereby reducing the possibility of degradation and impurity mixing, and reducing the problem of slipper black line.

Improve surface quality:

Silicone masterbatch can improve the surface gloss and smoothness of plastic products, making the product surface smoother and more even. This helps reduce visual defects caused by rough or uneven surfaces, including black lines and other issues.
