What Is the Dielectric Strength of Industrial Corona Rollers?

What Is the Dielectric Strength of Industrial Corona Rollers?

According to data from Jinhang Machinery, the dielectric strengths of different coatings are approximately as follows: • Silicone corona roller: Approximately 400 inches/kW • Epoxy-coated corona roller: Approximately 500 inches/kW • Ceramic corona roller: Approximately 300 inches/kW

What should I pay attention to when purchasing a corona roller?

What should I pay attention to when purchasing a corona roller?

Different materials have different performance requirements for corona rollers. For example, plastic films require higher surface energy, while metal foils require higher cleaning effects. Therefore, before purchasing a corona roller, it is necessary to accurately understand the types of materials that are mainly processed on the company's production line.

How does the corona roller work?

How does the corona roller work?

Corona roller is a device that uses high voltage to generate corona discharge on the surface of materials, thereby changing the surface properties of materials to enhance their adhesion. It is one of the key components of the corona treatment system, and together with high-voltage power supply, treatment electrode and other components, it constitutes a complete working system.

What is the role of epoxy-coated corona roller?

What is the role of epoxy-coated corona roller?

The role of epoxy-coated corona roller: 1. Provide excellent electrical insulation performance 2. Protect the surface of the material and prevent damage 3. Improve the efficiency and effect of corona treatment 4. Corrosion resistance and extend equipment life

How to judge whether the coating of corona roller needs to be replaced?

How to judge whether the coating of corona roller needs to be replaced?

If the corona effect is significantly reduced (such as decreased adhesion of materials, poor adhesion of printing inks, etc.), it often means that the function of the coating has declined. In this case, replacing the coating is a necessary step to restore the treatment effect.

How often do industrial corona rollers need to be replaced?

How often do industrial corona rollers need to be replaced?

Ceramic rollers are known for their high wear resistance and good insulation properties and are suitable for high-intensity production lines. Its replacement cycle is usually between 18 months and 36 months, depending on the use environment and maintenance conditions.

Why does the electronics industry need to use Corona Roller?

Why does the electronics industry need to use Corona Roller?

As a highly efficient surface treatment equipment, the corona roller can significantly increase the surface energy of the material and enhance its bonding with other materials, thereby improving the quality and reliability of the product.

Which industries need to use Corona Roller?

Which industries need to use Corona Roller?

Industries that need to use corona rollers: packaging industry, printing industry, electronics industry, automotive industry, medical industry, construction industry, etc.

What is a corona roller? What does it do?

What is a corona roller? What does it do?

A corona roller is a device that treats the surface of a material by corona discharge. Corona discharge is a high-frequency and high-voltage discharge phenomenon. When the air between the high-voltage electrode and the surface of the material is ionized, corona discharge is formed, thereby changing the physical and chemical properties of the surface of the material.
