PE Pipe Corona Machine

PE Pipe Corona Machine:

Have you ever wondered why it’s difficult to write or print on plastic – why does the ink smudge when you rub it? The reason is the relative energy between the two surfaces, and the only way to solve this problem is to modify the plastic surface and increase its adhesive ability. The process that can do this is called Corona treatment.
Whether a liquid wets a material well or poorly depends mainly on the chemical properties of the liquid and the substrate. Wettability is the ratio of the surface energy of the liquid to the plastic material, measured in dyne/cm. Corona treatment ensures that the surface energy of the plastic is higher than the surface energy of the liquid by increasing the adhesion of the plastic surface.

As a surface treatment equipment, the PE pipe corona machine has significant advantages in the processing of polyethylene (PE) pipes, which are mainly reflected in the following aspects:

1. Improve Surface Adhesion

Ionized air introduces polar groups on the surface of PE pipes, significantly improving surface energy (up to 40-50 dynes/cm), making subsequent printing, coating or bonding more secure and reducing the risk of falling off.

2. Efficient and Continuous Production

Supports online processing without downtime or independent processes, and the processing speed can reach tens of meters/minute, which is suitable for large-scale assembly line operations and significantly improves production capacity.

The power of the whole set of PE pipe corona equipment is 10KW, and the power size can be adjusted freely.
1. The control cabinet has start-stop control and control display, and the slitting machine operation screen can also realize the same function operation.
2. There is a voltage-stabilized power supply in the control cabinet to prevent power grid fluctuations, and there is an air cooling system to keep the temperature in the chassis constant.
3. The control system in the control cabinet has protection functions such as corona power-on, corona readiness, fan wind pressure, and corona speed, and monitors the peripheral auxiliary working conditions of the corona equipment.
4. The equipment includes a variety of alarm protection functions, such as over-temperature, over-current, over-voltage and overload protection.
5. It can track various parameters such as the working status of the corona equipment, which is convenient for finding the working status record: the working time of the corona equipment can be checked, the fault record of the corona equipment can be checked, the power size of the corona equipment can be checked, and the working parameters of multiple corona equipment can be set.
6. The equipment includes protection alarms, over-current alarms, over-voltage alarms, and over-temperature alarms.
