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.

BOPP film data --

Advantages of BOPP film:
BOPP film is a very important flexible packaging material. BOPP film is colorless, odorless, tasteless, non-toxic, and has high tensile strength, impact strength, rigidity, toughness and good transparency.
BOPP film has low surface energy and needs corona treatment before coating or printing. After corona treatment, the BOPP film has good printing adaptability, can be printed in color, and has a beautiful appearance effect, and thus is often used as a surface layer material of the composite film.
Insufficient BOPP film:
BOPP films are also insufficient, such as easy accumulation of static electricity, no heat sealability, and the like. In high-speed production lines, BOPP film is prone to static electricity, and an electrostatic remover is required. In order to obtain a heat-sealable BOPP film, a heat-sealable resin glue such as PVDC latex, EVA latex, etc. may be applied after corona treatment on the surface of the BOPP film, or a solvent glue may be applied, or extrusion coating or The co-extruded composite method produces a heat sealable BOPP film. The film is widely used in the packaging of bread, clothes, shoes and socks, as well as the cover of cigarettes and books. The initial tear strength of the BOPP film is improved after stretching, but the secondary tear strength is very low. Therefore, no cuts can be left on both end faces of the BOPP film, otherwise the BOPP film is easily torn during printing and compounding. BOPP can produce sealing tape after coating self-adhesive, which is a market with a large amount of BOPP.
