White Pva Absorbent Sponge Roller With Pvc Tube For Pcb Cleaning Machine
This specialized roller is designed for precision cleaning in printed circuit board (PCB) manufacturing and maintenance processes. Combining a highly absorbent PVA sponge layer with a durable PVC tube core, it ensures efficient removal of contaminants, flux residues, and debris from PCB surfaces without causing damage. Below is a detailed breakdown of its features and applications.
Product Overview of PVA Roller Sponge
Structure:Absorbent Layer: White PVA sponge with open-cell structure for high liquid retention and controlled release.
Core: Rigid PVC tube providing structural stability and seamless integration into automated cleaning systems.
Design: Cylindrical shape with uniform thickness to ensure consistent contact with PCB surfaces.
Key Traits: Non-abrasive, chemically resistant, and lint-free to prevent contamination.
Material Advantages of PVA Roller Sponge
| Component | Material Properties |
| PVA Sponge | - High absorbency (retains water, solvents, or cleaning agents). |
| | - Resistant to oils, acids, and alkalis. |
| | - Reusable and durable under repeated compression. |
| PVC Tube | - Lightweight yet rigid for smooth rotation. |
| | - Corrosion-resistant and compatible with most industrial cleaning fluids. |
Key Applications of PVA Roller Sponge
PCB Cleaning Machines:
Removes flux residues, dust, and ionic contaminants after soldering or etching processes.
