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 ---

In the coating process, the coating gap is poor and the pole piece wrinkles are analyzed:

I. The phenomenon and cause of poor coating gap
1. Trailing
(1) Material: slurry material, viscosity, solid content, slurry (surface) tension
(2) Equipment: coating-back roller distance. speed of coating roller when back roller is opened. diameter of back roller. back roller surface material. back roller deformation. back roller and coating roller parallelism. back roller and oven front Rolls are not parallel. Tension in operation
(3) Operational aspects: parameters for head and tail adjustment 2. Head and tail are not parallel
(1) Material: the gravitational pull on both sides of the substrate
(2) Equipment: The back roller and the coating roller are not parallel. The back roller is not open when it is opened. The back roller surface is coaxial. The back roller and the traction roller are not parallel. The level changes. (3) The tension roller adjustment state.
