How to solve the issues of filter clogging and white spots caused during processing in the rubber and plastic industry?

Mesh clogging and the appearance of white spots on the surface are two common yet challenging issues in the production of rubber and plastic products. These problems not only affect product quality but also significantly reduce production efficiency. To tackle these challenges, this article provides a range of solutions from equipment adjustments to material management.
 

1. Equipment Adjustments

1.1. Enhancing Physical Dispersion

Adjusting parameters of processing machinery such as temperature, pressure, and screw speed can improve the physical dispersion of raw materials. Good dispersion helps reduce the accumulation of raw materials on the mesh, thereby alleviating mesh clogging issues.
 

2. Powder Management

2.1. Moisture Control

Controlling the moisture content of powders during transportation and storage is crucial. High humidity can cause powder agglomeration, increasing processing difficulty and potentially leading to the appearance of white spots. Therefore, ensuring powder transportation and storage under dry conditions is key to addressing this issue.
 

2.2. Particle Size Selection

Choosing the appropriate particle size of powders is essential to prevent mesh clogging and enhance product quality. Powder that is too fine may lead to rapid mesh clogging, while powder that is too coarse may affect product texture and appearance. Selecting the most suitable powder particle size based on equipment characteristics and product requirements is an effective approach to solving this problem.
 

2.3. Surface Treatment of Powders

Surface treatment of powders can increase compatibility with substrates, improve dispersion, and reduce the occurrence of white spots. Such treatment methods promote uniform distribution of powders within plastic or rubber substrates, reducing issues during processing.

By implementing the aforementioned strategies through meticulous equipment adjustments and precise material management, mesh clogging and white spot issues in rubber and plastic processing can be effectively addressed, thus enhancing product quality and production efficiency.
