Brif Intro of PP plastic sheet

Surface corona ورقة البلاستيك PP plays an important role in many applications, especially when it is necessary to improve surface adhesion.

Surface corona treatment of PP plastic sheet is a commonly used surface modification method. By ionizing the air under the action of a high-voltage electric field, active plasma is generated to bombard the surface of the PP sheet, causing chemical reactions such as cross-linking, oxidation, and chain scission on the surface, thereby changing the physical and chemical properties of the surface of the PP sheet. The surface roughness of the PP sheet after corona treatment increases, the surface energy increases, and the wettability improves, making it easier to bond, print, and coat.

Features of surface corona PP plastic sheet

Surface energy improvement:

Polar group formation: Corona treatment forms polar groups (such as hydroxyl and carboxyl) on the surface of the PP sheet through high-frequency and high-voltage discharge to increase the surface energy.

Improved wettability: The surface wettability of the treated PP sheet is significantly improved, which helps the adhesion of inks, coatings, and adhesives.

Physical and mechanical properties:

Maintain original properties: Corona treatment mainly changes the surface characteristics and does not affect the basic physical and mechanical properties of PP sheets, such as strength and toughness.

Slight oxidation: There will be slight oxidation on the surface, but it has little effect on the overall material properties.

Treatment depth:

Limited surface treatment depth: Corona treatment mainly affects the molecular structure of the surface layer of the material, and the treatment depth is usually at the micron level.

Advantages of surface corona PP plastic sheet

Improve adhesion:

Enhance printing effect: Improve the adhesion of ink to the surface of PP sheets to ensure printing quality and durability.

Improve coating adhesion: Enhance the adhesion of various coatings (such as UV coatings, paints, etc.) on PP sheets.

Enhance bonding performance:

Better adhesive adhesion: Corona treatment improves the adhesion of adhesives and is suitable for applications that require bonding, such as labels and packaging.

Diverse applications:

Suitable for various surface treatment needs: Widely used in packaging, printing, coating and other industries.

Environmentally friendly and efficient:

No chemical reagents: Corona treatment does not require the use of chemical reagents and is environmentally friendly.

Efficient and fast: fast processing speed, suitable for large-scale production.

Production process of PP sheets

The production process of PP plastic sheet mainly includes the following steps:

  • Raw material preparation: Mix and stir PP resin, additives and other raw materials.
  • Melting: Send the raw material mixture into the melting machine for melting.
  • Extrusion: Extrude the molten PP material into a film through an extruder.
  • Cooling: Cool and shape the extruded film.
  • Winding: Wind the cooled and shaped film into a coil.

التعليمات

Q1. Why do you need to corona treat PP sheets?

Answer: PP sheets have low surface energy, and corona treatment can significantly increase their surface energy and enhance their adhesion to inks, coatings and adhesives.

Q2. Will corona treatment affect the basic properties of PP sheets?

Answer: Corona treatment mainly changes the surface characteristics of PP sheets and does not significantly affect their basic physical and mechanical properties.

Q3. How long will the effect of corona treatment last?

Answer: The effect of corona treatment will gradually decay over time. It is usually recommended to perform subsequent processing (such as printing, coating or bonding) as soon as possible after treatment.

Q4. Does corona treatment have any impact on the environment?

Answer: Corona treatment does not require chemical reagents and is an environmentally friendly surface treatment method with little impact on the environment.

Q5. Is corona treatment suitable for all types of PP sheets?

Answer: Corona treatment is suitable for most types of PP sheets, but the specific effect depends on the formulation and initial surface characteristics of the PP sheets.

Q6. What is the cost of corona treatment?

A: The cost of corona treatment is relatively low, especially in large-scale production, its high efficiency and fast processing characteristics can reduce unit costs.
