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.

PET film--

 

(5) PET antistatic film
The world today has entered the information age. Electromagnetic waves of various frequencies and wavelengths fill the entire earth space. These electromagnetic waves will cause different degrees of interference to unshielded sensitive electronic components, circuit boards, communication equipment, etc., resulting in data distortion. Communication is disordered. The static electricity generated by electromagnetic induction and friction on various sensitive components, instrumentation, certain chemical products, etc., such as high voltage discharge due to static accumulation of packaging film, the consequences will be destructive, so the development of antistatic PET packaging film is also very important. The antistatic film is characterized in that an antistatic agent is added to the PET film to form a very thin conductive layer on the surface of the film, and a continuous phase is formed to improve the surface electrical conductivity and cause the generated electric charge to leak as soon as possible. Generally, the surface specific resistance of the antistatic film is ≤109~11 ohms.

(6) PET heat sealing film
Ordinary PET is a crystalline polymer. When the PET film is stretched and oriented, it will produce a large degree of crystallization. If it is heat-sealed, shrinkage deformation will occur, so the ordinary PET film does not have heat-sealing properties. When PET film is used as a commodity packaging, in order to solve the problem of heat sealing, a method of compounding a BOPET film with a PE film or a CPP film is generally adopted, thereby limiting the application of the BOPET film to a certain extent.
In order to solve the heat sealing problem, a three-layer co-extruded heat-sealed PET film, a heat-sealed PET film, has been developed by modifying a PET resin and using an A/B/C three-layer die. Since one side is heat sealable, it can be directly heat sealed and is very convenient to use. The heat-sealed PET film can be widely used in various commercial packaging and card-protecting films
