How to prevent static electricity and adhesion of the film during the operation of the plastic film slitter?

Preventing static electricity and adhesion phenomena in plastic film slitters is a crucial aspect to ensure smooth production processes and product quality. Next, let's explore how to effectively address these two issues in an informative manner.

Let's first discuss how to prevent static electricity in the film. Static electricity is mainly caused by the uneven distribution of charges when plastic film rubs or comes into contact with other objects. Static electricity can not only cause the film to attract dust but also affect the cutting efficiency of the film. To address this issue, we can take the following measures:

Humidity control: Maintaining the humidity of the operating environment within an appropriate range, typically around 50%, is ideal. Increasing humidity helps reduce static electricity generation because moisture can help balance charges.

Use of antistatic agents: Coating the surface of the film with an antistatic agent can effectively reduce the film's static electricity. Antistatic agents are usually special surfactants that can absorb moisture from the air, forming a conductive layer to prevent static accumulation.

Use of ionizing blowers: Ionizing blowers can generate a large number of positive and negative ions, which neutralize the static charges on the film surface, thereby eliminating static electricity. Ionizing blowers are typically placed above the film transfer path to ensure thorough static elimination as the film passes through.

Next, let's look at how to prevent film adhesion. Adhesion phenomena are usually caused by excessive adhesive forces between films or by heat generated during the cutting process causing the films to melt and adhere. To address this issue, we can take the following measures:

Selection of suitable film materials: Choosing low-adhesion, easily cuttable film materials can fundamentally reduce the occurrence of adhesion phenomena.

Optimization of cutting parameters: Adjusting parameters such as cutting speed, pressure, and temperature of the slitter to ensure a smooth and rapid cutting process reduces the possibility of heat generation and film melting.

Use of anti-adhesive agents: Coating the film surface with an anti-adhesive agent can effectively reduce the adhesive forces between films and prevent adhesion phenomena.

Cooling system: Slitters are typically equipped with cooling systems to quickly reduce the temperature of the cut film, preventing melting and adhesion.
