1, release film
1,1 Introduction
A release film refers to a film having a separation surface which is not sticky or slightly viscous after contact with a specific material under limited conditions.
Usually, in order to increase the release force of the plastic film, the plastic film is subjected to plasma treatment, or fluorine treatment, or a silicon release agent is applied on the surface of the film material, so that it exhibits for various pressure sensitive adhesives. Extremely light and stable release force. According to the different release force of the release film, the viscosity of the insulation product is different, and the release force is adjusted accordingly, so that it achieves extremely light and stable release force during peeling.

• 1.2 release film classification by substrate:
> PE (polyethylene) release film;
> BOPP (polypropylene) release film;
> PET (polyester) release film.
Classified by release force:
>Ultra-light release liner (<5§)
>Light release release film (5-10g);
> Medium release release film (10-50g);
>Removal release film (50g or more).

Classified by silicone oil coating:
>Ordinary silicone oil release film >Fluorine plastic release film
>Other categories: such as high temperature silicone pressure sensitive adhesive.
Classified by surface color:
A red release film, a yellow release film, a green release film, a blue release film, a white release film, and the like, and a PET release film of various colors.
Classification by substrate surface treatment:
Single-sided release film, double-sided release film, no-free release film.

Coating machine knowledge handout ---

The general process flow for pole piece coating is as follows:
Unwinding → tab → traction → tension control → automatic deviation correction → coating → drying → automatic deviation correction → tension control → automatic deviation correction → winding
The coated substrate (metal foil) is discharged from the unwinding device and supplied to the coater. The first end of the substrate is connected to the tensioning device by the traction device after being connected into a continuous belt, and the tension adjusting device and the automatic correcting device are fed into the coating device after adjusting the tension of the film and the position of the film. The pole piece slurry is applied in sections of the coating apparatus in a predetermined coating amount and a blank length. When double coated, the first side coating and the blank length are automatically tracked for coating. The coated wet sheet is fed to a drying system for drying, and the drying temperature is set according to the coating speed and the coating thickness. After drying, the pole piece is subjected to tension adjustment and automatic correction, and is wound up for processing in the next step.
     The key to the coater is to be stable. After a parameter is adjusted, it may last for a whole day. If there are any variables in the coating process, the impact on the battery performance will be great. Although the stability of the coater is important, the mastery of the operator is particularly critical. A good operator not only operates the equipment, knows how to maintain the equipment, but also knows what causes the problem when there is a problem in the coating process. What is the main reason for this problem? How to solve it. It is both a qualified operator and a good equipment maintenanceman.
